This is the opinion of some Western thinkers and the Orientalists. We should shed light on this heritage, study and criticize their joints, and refer to the Islamic intellectual assets and sources of confusion in it. The research paying attention to the philosophical study of Islamic architecture (based on intellectual assets) and the root of this study to clarify the difference between (Islamic architecture) and (Architecture of Muslims), so the discovery and identification of critical joints of Islamic architecture will reveal a large part of this difference. Critical studies around the Islamic architecture is not sufficient to solve the problem of critical fact that do not rise to the production of solid intellectual foundation, for the shape of the Iraqi Islamic school, so the provision of critical examination philosophical critique of critical joints in Islamic Architecture (after detection and identification), it will save our societies from the paradoxical situation and the intellectual antagonism experiencing at the present time between trends and theories of Western, and Islamic intellectual needs (which may conflict with these directions).The critical joints in Islamic architecture will also have a critical rule through criticism of Islamic buildings ,and global with it , and to identify "critical joint " is the change that is made on a continuing phase and change it to another phase may be negative or positive, through the themes and architectural studies on the philosophical architecture on Islamic critical joints can be concluded in Islamic architecture and can develop the physical reality, and to give a clear vision about the need for the future " , sources of architectural form , Architecture relationship to man , subject and object and their relationship to architecture, Architecture as an object, Rule and order in Islamic architecture, engineering and mathematical relations in Islamic architecture, criticism of Structural in architecture and criticism of phyenomenology in architecture.The current architecture is not one that attaches to the research priorities and research attention, while attention is the need to shape an idea of the future Islamic Architecture (stemming from the Islamic asset),The study of the Islamic intellectual assets and production techniques architectural forms entrench us information theory to compare them to shape and develop our idea of the Islamic school for the future.The need for actual criticism will appear , in the criticism of Western theories and trends that apply to the Islamic bulildings now (or criticize the buildings) and was founded by intellectual analysis and comparison of what is ours from the Islamic intellectual assets, to distinguish in line with the thought and contrasts with, in essence. These trends are (Phenomenology, Existentialism, Structuralism, and Marxism).The search is now paying attention to (Islamic architecture), the Islamic heritage of intellectual (and spiritual), and the need for Islamic architectural future, Our architectural path need a clear objective aim, and future - oriented stems from the genuine Islamic thought to occupy a position of real Islamic architecture.

Abstract: تعددت الدراسات المتعلقة بالجمال والجماليات المعمارية، كما تنوعت الحقول التي قامت بدراسة كل منهما، مثل الفلسفة وعلم النفس والاجتماع. فقد شغل الكثير من الفلاسفة بموضوع الجمال، واستمر البحث فيه وفي مصادره في مختلف العصور، وقد حاول علماء النفس والاجتماع وضع ت | Many studies were made about beauty and architectural aesthetics, as a variety of fields, which had studied each, such as philosophy, psychology and sociology. Beauty was always philosophers’ concern, and continued research it and it sources in various ages, psychologists and sociologists tried to find interpretations of the aesthetic experience according to their attitudes. The values were still the subject of research and study to this day. They were studied by philosophers, sociologists and psychologists and also by architects to see their influence on architecture. This research is a mere attempt to have a better understanding of the subject of beauty and its sources and its impact on the architecture and how to accept it and deal with it. From which the research’s problem appear which is the attempt to find the influence of the value situation on the architectural aesthetics of the Iraqi contemporary architecture. The research tries to combine the subjects of architectural aesthetics and values, and identifies the rule that values have in the matter of “aesthetic taste” for individuals and societies. Proceeding from the idea that beauty could be in subject or object or both, the research discusses the impact of values or values sequence in society on those two factors (subject and object). Thus the theses suggested to solve the research’s problem included the necessity of the value situation, which depends on not only philosophical bases but also social factors, to understand the architectural aesthetics; the second thesis included the importance of values’ situation to direct the “aesthetic taste”. The third thesis was says that due to the inconsistency of the political, economical and social situations in Iraq, a case of confusion in the aesthetic preference appeared, which requires finding the criteria to solve this problem.Values have different sources, their power and obligation increase according to the power of their sources. So in order to study these values the research went back to their sources to further understand them, then analyze their impact on the subjective and objective factors of architectural aesthetics. Chapter one of this study included the discussion of values, beauty, aesthetics and attitude, with a brief demonstration of their history and sources. While chapter two discussed architecture and it’s significance for society, then found that architecture carries the values of the society and thus it’s aesthetic sense, chapter two also gives a brief description of contemporary Iraqi architecture and the most important events that effected it. As for chapter three, there is a summery for all the information and conclusions made throughout the study and a subtraction of the main terms that form the objective and subjective characters of the architectural aesthetics, then they were put into comparism with the value situation to find their effect on aesthetics, then these relations were applied to examples of Iraqi architecture, the study found in the forth chapter that the relationship between values and aesthetics is strong, for both subjective and objective terms, because values are indicators and rules that society follow, and as long as the architecture follows these rules - values - it would be accepted by society and beautiful, and this is one of things that gives identity of architecture in a certain place and time The study also found that if the society was well connected and had strong and sacred values, its architecture will carry its identity and stands for its as well as all it’s arts.

Abstract: من دون شك ان ظهور العمارة ,انما يعود الى زمن بعيد وقديم قدم الانسان , فقد بدا الانسان البحث عن ماوى ومسكن يسكنه ويؤويه,ولهذا يعد السكن من المتطلبات الاساسية وضرورة ملحة في حياة الانسان سواء كان في الماضي او في الحاضر ام في المستقبل.ان توفير السكن يعتمد عل | It's well known, the architecture began in human age by searching for a shelter being the basic necessities depending on housing policy of the and its permittance t community sectors (state, private, co - operative) to cover housing requirement. The progress and development of any state is measured to its sympathy with such requirement and on its capacity to secure affordable house to community's privates.In accordance, the importance of the research being deal according to housing philosophy concept with these serious aspects that related with wide social classes of Iraqis due to certain circumstances.The importance of the research depending on the need of securing the requirements of wide classes of population to suitable housing utilities (new and rehabilitating the excited ones) that cover the requirements of shelters, moreover : to find solutions within development - plan for such lack in short and medium terms.Therefore, the research, complication is to reach to clear image of unify various housing aspects according to the Islamic doctrines, the research assumed that the indications which solve the housing demand problem depend on the sustainable balance in the composition of the housing system. and the Islamic doctrines is the best concept to follow, because it give complete concept taking the real solution with objectivity ,doesn't separate from the incorporeity dimensions, ad take care for the human condition.The research remarked to various conclusions to solve housing crisis by mixed strategies starting by adopting some of the state to Islamic thoughts, using sustained balanced, solve the lack in housing frame, changing the related laws and regulations, legislating social solidarity, activating the role of co - operative societies And the research has some important recommendations, have been extraction from the research indications.

Abstract: العمارة ليست حج ا ر؛ ولكنها الفكر الذي يقبع خلفه والسابق لعملية التصميم؛ فيمكن ايصال ذلك الفكر عن طريق الاشكال والرسوم او الصور او حتى كلاميا؛ ويلخص ذلك كله عن طريق مفهومي النمطية والنمط في التنظير المعما ري من خلال تحولاتهما عبر العصور؛ فالنمطية ه | Architecture is not a stone; It’s the prior thought behind design process; which could got from Forms; sketches or images and even verbally; and all summarizes through the concepts of Type and Typology in Architecture by its time transformations; Typology is architecture itself, it’s represent era imprint and it’s classifying Architectural movements, including its philosophical and theoretical ideas and even the applied. That’s made the Theory of Type in architecture deals with the thoughts and stone. Therefore the research aim is to mention the meaning transformation of the Type and Typology concepts; and clarify specific definitions for each of them; which considered challenge due to the conception transformation for them and their wide uses in the other fields. So, the research aims to examine type and typology importance in architecture, and the importance for the type double nature in the self - formal construction due to the culture fluencies and mixing. The research problem on how the Architecture benefits from the overall type theory, from the overview of preliminary research and chapters.Type is the active autonomous tool in the architectural design, and it’s the idea behind the image transferred to the observer. Although of the types’ prior existence; but it’s discovered according to its position; since the types are classified according to their positions; therefore the Ideal Types are the types in the Ideal world which it’s prior existence and its first physical presentation called the Prototype; after that the repetition of the prototype calls Stereotype; and due to these repetitions of the Stereotype; the type stand in the human mind and be as a human nature; when the type reaches to this position it is calls Archetype. And there are many other types classified according to their essence and formal properties; example : Active Type, Developed Type and Originating Type and others. The need of type and its origins theory research to define and discover the importance of the Type in language and architecture, and discuss its theoretical and continuity concept, as well as in autonomous architectural view with concept like Form, Meaning, Function, and Material.In the other hand, Typology stands in the theory of typology which is filled with meaning and different from the first half. It describes the era properties by the Typology Succession Process; therefore the research aims to define the architectural Typology by discussing its concept and importance in architecture. And explores the elementary and mechanical Typology and their properties, and its legitimacy in architecture.In Architecture which is the research third revolve; the importance of the Type and Typology Concepts in practice; for discussing great cases in architecture like first architecture origin. Although the bid difference between the rationalism and empiricism; they agreed that the type is the origin in first architecture; and it’s extrude all the architectural splendor of luxury. The Type Theory used in understands and analysis all architectural projects; since it’s the real standard in the architectural appreciation; and is giving real picture for the different types benefits in these projects. In spite of possibility project presentation according to many types; but some types are more useful from others in a project. These projects are decided by theory of type or by providing new types to meet the needs of the community. As well as; Theory of Type clarifies the accurate joints between typologies and the architectural revolutions in the history; the classical typology for example; adopted on the theory of complementarily with nature against which earlier in the architecture of the Baroque and Rococo; by its imitation with the Greek or Roman model. Where the theory of Typology tell us by the two typologies (classical and the pre - classical in baroque & rococo) are different, but they are not opposing; as is the case between Modernism and Classicism; they both derives their legitimacy from other sources outside architecture, in the other hand; the unitary holistic view of the modernism typology helped to break architect character and the architectural work in the community. But the city typology different from the previous typologies; it’s take its legitimacy from the architectural field, trying to fix the modernism faults by using the collective memory which stands in the human minds. The Conclusion is reviewing summarizing of previous chapters and put forward recommendations and the beneficiaries of the research.

Abstract: shall be treasury of knowledge which is a source of ideas and action, The act of human is a reflection , an expression and embodiment of the need, or desire. in the field of architecture, the design action is a result of the need for human safety , and self - realization, and the social and psychological needs, therefore, shelter of the first human needs, express the idea of first body reaction (the product of intellectual and physicist), varied between spontaneous and intentional : the planning and thinking preconditions for his idea, function, and method of installation elements and parts, according to what provided to him by intuitive logic of the board of formality, and the installation of the elements and materials provided by the surrounding environment. The idea was to model the architectural design for a variety of experimental methods of possible alternatives, and became the first structural model, which tried the alternatives and possibilities it is the model (fixed) within a spatial environment. technological first designing act consists of spontaneous Technologyrepresenting the factors of chance and subjectivity, and the process of repeating the form of productive to make it objectively, and traditionally the advancement of technology and its evolution, dominated by aspects of intentionality, guidance utilitarian, and substantive output, but man still seek spontaneous ways of thought embodies the products of creative spontaneity of the self, and the other overlap and coincide with the utilitarian aspects. This formulated the general problem of research as follows : try to reach a clear vision about the relationship between Spontaneity and intentionality in human action, and through the knowledge presented in the first quarter, research has come to formulate a knowledge problem then propose hypothesis as follows : What is the relationship between Spontaneity and intentionality in the designing act? And What is the role of subject of place in that relationship? Were assumptions reflect the main objective of the research and that the classification of the possible relationships between both sides of the spontaneous and intentionality and determine the factors underlying those relations and formulations following : major premise : the relationship between Spontaneity and intentionality in the act of Architectural Design is one of the relations of the three : overlap or match or contrast. The Secondary assumption : The type of the relationship between Spontaneity and technological intentionality in the act of Architectural Design deepened on : self creativity in dealing with the subject and the properties of place.Accordingly, the search mode theoretical framework included the chapters I and II, where the first chapter discusses the vocabulary of human action, and the concepts of Spontaneity and intentionality of technology, according to object and subject, and between ration and experience and referred to the concept of creativity as an act of self - conscious and explained the beginnings of a relationship between the spontaneity and intentionality in the Place. The second chapter dealt with the concept of place and definition of the most important characteristics, givens, on aspects of subjective and objective in the spatial characteristics, and their relationship to the creativity of self in the act of architectural design, and then draw the most important vocabulary and knowledges of the theoretical framework through the third chapter, which ends with two sets of indicators, the first group of indicators helps for analytical overview of the examples of (Chapter IV), which included : first housing in the villages of northern Iraq, and the school of the Baghdad, and the Pyramid of Cheops at Giza - Egypt, and the building of the Louvre Abu Dhabi, and the Centre for arts and music Abu Dhabi, and the building of Chinese television in Beijing, and units of student accommodation in Marseille - France. While the second group of indicators helps to test the validity of the hypothesis of the research, through two ways , first by the analytical tables and charts, and the second by the questionnaire (a comprehensive set questions posed to experts in architectural field).then the research ends with conclusions and recommendations, which revolves around the following points : classification of the relations between Spontaneity and technological intentionality in the act of architectural design, and (creativity of the self in addressing the subject) and subject (place), and dealing with the final conclusions of the points on the relationships of self - characteristics of the place where the designer especially based on the perceptions and experience, an attempt to highlight the impact of self in the act of architectural design and re - focus on their potential creativit.

Abstract: تحقيق التوازن مع الطبيعة هو الهدف الذي تسعى اليه الجهود المبذولة من قبل العلماء والمصممين على حد سواء خصوصا مع المشاال المتزايدة التي تهدد عالمنا اليوم. وقد استغلت قوانين الفيزياء باعتبارها قوانين مستنبطة من الطبيعة من اجل تحقيق هذا الهدف ونتج عن ذلك ظهو | Achieving the balance with nature is the aim that all efforts of architectures and scientists trying to achieve especially with the increasing problems that threatened our world today. The laws of physics have been used as it is a law from nature to achieve that goal. resulting from that , the concept of sustainability that goes through all fields of life emerges to us with architectures like sustainable architecture, green architecture and Gaia architecture.The way to achieve sustainable architecture needs a full description to the relation between architecture and physics and goes in depth of this relationship.So the research general theses problem emerged that” there is few studies in complete vision about the concept of correlation between physical field and architecture from the theoretical concepts and the basic components that the concept embedded”. The minor thesis embedded that ”There is ambiguity in how to specify and act the physical laws by the designer and his interaction with it to give a touched result on the physical level “ , the research theses indicates “There is ambiguity in how to specify and act the physical laws in producing sustainable architecture”.The research aims to spot the light on this relationship between physical laws and architecture and examines its sustainability, and to make full use of natural laws available in our hands to produce sustainable architecture.The research structure has been built through 5 chapters : - First chapter : dealing with the intellectual theses and local studies that deals with the research problem “physics and architecture” to conclude the research problem and specifying the aim and methodology. - Second chapter : build a theoretical informational basis of physics and its relation with architecture, taking in consider the graduation and evolution of this relationship, and the main philosophical characteristics that reflected in architecture. - Third chapter : building the theoretical structure through polarizing the relation of physical laws with architecture so the special theses has been produced, which deals with the relation of physical laws with architecture, to conclude the variables that have beenexamined by applying them on a collected projects which is being agreed on its sustainability , so the research hypothesis has been formed and the final variables have been adopted as a measurable variables in the applied chapter. - Fourth chapter : specifying the way of measurements adopted and the definition of selected projects and making the practical study through applying the theoretical variables on an architectural projects. - First chapter : the final result of the study has been given , represented in : results correlated with theoretical structure , results correlated with practical side ending with the recommendations and future studies that grows from the research.The result of the study that the research has been reached to : is that the sustainable architecture is the architecture that achieves and embodies the physical laws on the theoretical, physical and functional level. Also the research has been reached to the following conclusions.

Therefore, research take urban design policies and methods with regard to urban renewal for the Future of Urban best of these cities and assimilate the age and its challenges, thus identified the problem of research the future development of cities with traditional historical roots and their attitude towards the immediate challenges of the age and the role of urban renewal policies in that. And define the research aims by providing knowledge on traditional cities with the historical roots by discussion over the physical characteristics and non - physical and put the challenges facing these cities to identify the most important urban renewal strategies best suited to the nature of these cities that represent the origins of Action for the future development of these cities. Assumed that the traditional cities of the historical roots of many of the constants and parameters relating to physical characteristics and non - physical characteristics for such cities as it faces significant challenges in light of the evolution of the times, therefore, the existence of a future vision for how those cities in the near future is a necessity for urban renewal policies and selection Most of which is key to the city's future and be absorbed by the immediate requirements of the age as a Predictive. The research methodology adopted analytical and descriptive in the theoretical framework, and practical framework has been selected five global examples (Arab and Western) that represent the cities of the future rooted historical and civilization heritage, The results showed the effectiveness of urban renewal policies in the future development traditional cities with historical roots and absorb solutions thereby realizing convoyed the age and preserve the cultural heritage and inspire cultural heritage at the level of details or potential sleeper, which is considered some of them as solutions to the challenges of the times, and the varying policies of urban renewal in accordance with the importance of Heritage area in addition to other factors, has focused on preserving areas of high architectural value with a flexible approach to preserving and reviving the architectural heritage and linking it with the whole city, and adopt a principled rehabilitation in areas of moderate architectural value terms allow for modifications and additions - run of the existing buildings to stimulate economic, social and cultural life, and adopt a principled urban infill in urban areas that have been rehabilitated vacant and destroyed spaces, the principles re - development, follows in areas outside the boundaries of traditional areas of inheritance Civilized, and revitalization follows at the level of a whole city, connecting the previous policies.

Base on this problem to be done the primary vision to the aims of this research and its method and framework to be requisite now reaching to method for untying this problem, So the chapter one give the inclusive definition of technology in public and explain foundations of technology, then explain the important sides of technology which is the structure side with all there nature conception, features and classifications. Also the nature of structural material that effect on structures choice and treating with them from functional, aesthetic - expression sides. While the chapter two have the second side of this relation that represented by the architectural product with all there features and the architectural form's nature and it sources and the extraction of important factors that effect on architectural form from functional, aesthetic - expression sides. then display the important items of theoretical framework that extracted from chapter one and chapter two. The theoretical frameworks consist of three levels are : " structural level, formal level and the relation nature between them. Chapter three have two axises, the first contains a public study of Contemporary Architecture to reach the effect of form on structure and other wise, while the second axis contains an application study for untying research problem that had taken by five projects and determine the basis choice of theses projects and that done by applying the theoretical framework's primary and secondary items on these projects ,By that it had explained possible limitation for the theoretical frameworks application and description the cases that actualized the effect of technology on integrated of architectural structure systems that can be got by defining this effect and the how to actualize on the all five projects.finally Chapter four contains a discussion of results and define the finally conclusions of this research with explaining the research recommendations ,future studies and foundations that willbenefit from this research.

Abstract: Civilization Interaction is an everyday life process that affects the city centers and that encourages their continuity in times and discourages them in others, in certainrelation between two : dialogue and conflict. This principle was the basis of study of one of the important phenomena related to the human existence : interaction betweencivilizations, whether dialogue or conflict, and the relation of these two poles on many levels and through many mechanisms, and the effect of this process on city centers positive or negative, according to the relation of these two poles and because that dialogue and conflict represent opposing extremes of the same phenomenon. Thecivilization interaction is changeable, sometimes the dialogue pole dominates, and sometimes the conflict pole. This is reflected on the city centers development. Theabsence of the comprehensive understanding of the co - existence of the two poles within this single phenomenon in architectural and non - architectural theses about thissubject is a reason that initiated this research. Accordingly, the research problem was formulated as " researching for the positive and negative factors in the process ofinteraction among the civilizations which happenes within the circumstances of occupation,and explanation of the degree of the circumstances on the process of interaction between the civilization of invader and the country which below the occupation.. The research theoretical goal is formulated as "to diagnose the change patterns that occur in historical city centers and define their nature, the change effected by the imposition of other civilizations (occupations) on the local ones (within the framework of the dialogue and conflict bipolar equation).On the practical level : the above - mentioned theoretical principles are applied to carefully chosen reallife examples. Using the analytical inductive methodology, the researcher has divided the research into six chapters : chapter one is dedicated to present a general introduction to civilization interaction and its effect on the changeability of historical city centers by listing and criticizing previous relevant researches and theses. Chapter two is devoted to discussing the concept of civilization and civilization interaction through many theses about the civilization interaction within its two poles, the factors that encourage this process and its levels and the alternation of this phenomenon between the poles. Then this relativity is further clarified through shedding light on city and its historical center that witnesses the process of the civilization interaction and the change of this center negatively and positively according to the relative movement between the two poles of the civilization interaction process and its effects on the variables of the center. Chapter four is devoted to build the theoretical framework through understanding one of these factors : occupation factor as one of the civilization interaction factors along with its two poles and the effect of this factor on the changeability of historical city centers within a mechanism of movement between the two poles of the process, through the analysis of chosen historical city centers of occupied civilizations affected by the civilization interaction, be it positive or negative, depending on the movement of the two poles of the process, especially regarding the urban expansion as a result for this factor. The research explain the existence of a gap in the knowledge in terms of relations, such as the relations of the two poles of the civilization interaction, the relativity of relationship between them, through the analysis of historical city centers within the civilization interaction process, affected by occupation factor according to relative criteria to measure this relation, derived from the theoretical framework (that is studied in Chapter four) and explained in chapter five (the practical application). The relation between the two poles of the civilization interaction was studied, along with their effect in the changeability of the historical city centers (of Baghdad, Aleppo, and Jerusalem).Chapter six is divided into two axes; the first was reserved for the conclusions from the research, while the second one is dedicated recommendations of the resear.

This forces us to depend on other sources than the current ones. The field of architecture is directly associated with the energy issue, the research to study the conditioning of architecture with energy was about the solar architecture by the virtue of the sun being a non - depleted alternative source to be utilized technologically. The research was concerned in the study of all current and future techniques of solar energy. The core of the research was : Give acknowledgment about the role, important and capability at implementation of solar energy as non - depleted source in the sustained environmental design. This query led to emergence of ancillary knowledgeable problems about the implementable technological means in Iraq which depends on merger of the passive and active means and its techniques that suit the climate of our zone. The goal is to provide acknowledgement about the importance of solar energy and identified the modern means, techniques and implementation of this energy in sustainable design compatible with the hot dry climate of Iraq. The research relied on the assumption that merger of passive and active design in the solar design is the optimum guarantee for realization of maximum benefit from such energy. Chapter 1 dealt with energy’s topics, sources and its current problem, it put forward the most important current and future alternatives. Chapter2 focused on solar architecture in the domain of climatic design as an important environmental solution for the problem of energy depletion. Chapter 3 put forward the most important techniques of solar energy. In chapter 4 many local, Arab and global examples were presented for comparison with its solar treatment methods and followed techniques. The purpose is to get the best conclusion and recommendations for dealing with the circumstances and specificity of our region and its hot dry climate and that was by the combination between the two systems of solar design to ensure that the building is self conditioned and then powered it with the energy.

Abstract: Crisis represents one of the most important factors that lead to radical changes in the city systems within a short period of time, and because of the war being one of the most important causes and results of a crisis; therefore war changes the city systems in different aspects.The war mechanism mainly depends on its destructive energy which affects directly the city systems, as well as its physical and symbolic components; nevertheless, the city constantly tries to balance itself by controlling its changing elements in the reconstruction process to form a new balanced state.A comprehensive theoretical framework capable of building integrated basic concepts about reconstruction of cities influenced by war and its effects on urban patternschange was absent in the literature.This have led to the creation of the basic research problem which is "the lack of a professional knowledge concerned with the concepts of city urban patterns and their changes during crises."Therefore, the aim of the research is to clarify the physical relation between war and the patterns of urban fabric. This will be done by studying the effects of the war massive destructive energy on the urban patterns through related literature such as chaos theory and its applications in mathematical field (fractal geometry) which will help in establishing a database concerned with the concepts of crisis, war, pattern, fractal and change. In order to accomplish this aim the research suggests a main hypothesis, which is "the war may demolish the fractal characteristics of the urban fabric by changing its patterns" and a secondary hypothesis "the reconstruction process plays a vital role in controlling the fractal characteristics of the urban fabric".The research structure comprises chapters discussing the research fundamental concepts by implementing a scientific analytical methodology and chaos theory since the war is an unpredictable state with high energy that follows non linear path and a wide range of probabilities.Chapter One comprises introduction and the literature review which is of great importance in determining research problem, aims, hypothesis, and methodology.Chapter Two discusses the nature of crisis and war by studying their types, conducts, mechanisms, and theories to extract the interrelationship between them; ultimately the chapter ends with discussing their damages to the system.Chapter Three discusses the nature of pattern and its changes by studying its components, types, mechanisms, and theories in order to recognize pattern's necessity for the continuity within the urban fabric.Chapter Four discusses the theoretical framework of war and pattern change by investigating how the crisis may deform the fractal properties of the urban fabric through transforming the existing physical patterns.Chapter Five is the practical application of the theoretical framework which tests a number of regional and international examples by applying the research hypothesi on a number of selected samples and finally proves the validity of the research hypothesis in Baghdad reconstruction proposal.Chapter Six finally ends the research with conclusions and recommendations to sustain the fractal characteristics of cities damaged by wars, through reconstructing structure from the beginning with the appropriate trends of reconstruction; otherwise the inevitable patterns that develop as a result will cut across the original fractal properties.

Abstract: This work presents an experimental study of the drag - reduction performance of two water - soluble polymers, Polyacrylamide(PAAM) as flexible, linear synthetic polymer and Xanthan Gum(XG) as a rigid polysaccharide from natural resources. The flow loop used consisted of 0.5 O.D. inch straight pipe with a test section of 3 m length. A 0.5 inch O.D. vertical tubing with elbows was also included to compare the drag - reduction behavior between both tubing configurations. Various concentrations of polymeric additive and water flow rates were tested. The results show that the drag - reduction in vertical piping are significantly lower than in straight type for both polymer type. The dragreduction efficiency of Xanthan Gum agent is much lower than polyacrylamide. Higher concentrations of XG about 150 ppm is required to get exactable drag - reduction performance about 12.84% in the straight pipe. While about 40.3% drag - reduction was achieved with about 50 ppm Polyacrylamide with the same conditions. Moreover, the drag - reduction efficiency of XG can be improved by mixing with Polyacrylamide agent at a given conditions.Part of the experimental work was devoted to study the performance of Polyacrylamide as drag - reducing agent with the existence of small amounts of sodium chloride acts as an inhibitor to the ability of the additive, resulting in lower drag - reduction probably due to collapse of PAAM at more compact structure with the addition of sodium chloride as strong ionic salt.Polyacrylamide and Xanthan Gum additive undergo undesirable mechanical degradation with increasing of circulation time, leading to lower drag - reduction performance. The molecular degradation is likely to occur at low additive concentrations and low turbulence flow, in vertical piping, since the polymeric additives are exposed to shear stresses.Further attempt was done in present investigation to find correlations for accurately predicting drag - reduction characteristics of drag - reducing agents, used in published works. A published time scale hypothesis for prediction of drag - reduction values, the friction factor data as a function of the polymer concentration, shear stress, Reynolds number, pipe diameter. The experimental friction factor results were taken from a published work for gas oil with polyisobutylenes. Good agreement between measured and predicted friction factor. Further attempt was made to correlate the mechanical degradation ability by modifying the Kouraush, Williams and Watt (KWW) equation. The experimental data were taken from a published work for Polyethylene Oxide. The modified equation was found to fit experimental data better than the original KWW equation.

An experimental investigation was conducted using 1litter stainless steel autoclave to treat the oily water produced from North Rumaila and Zubair oil fields. The first approach was a pretreatment to remove solid particles using sedimentation with and without flocculation. The second approach included studied the effect of pH, pressure, temperature, salinity, operation time, outlet time and RPM. The third approach was investigate the effect of the surfactants (detergents and alcohol) to reduce surface tension, finally, was addition of some sorbents like polypropylene, polyethylene, used plastic and sawdust.The ranges of salinity, pH, pressure and temperature were selected according to the PW conditions which out from dehydrator and desalter (80000 ppm, 6, 3bar and 60°C respectively), the RPM of mixer was selected to satisfy laminar flow, while the time of operation and outlet product represented the minimum residence time in batch reactor and its discharge to choose the minimum design cost. The results showed that the best conditions were : - Pressure =1 bar, temperature =45°C, mixer speed =300 RPM, treating time =15 min and skim time starting =5 minutes. Best additives to reduce surface tension : ethanol volume = 0.05vol %, powder detergent = 400 mg/litter and liquid detergent volume = 0.03vol%. Best sorbents : Sawdust amount addition = 2.5 gm, polypropylene = 4 gm, polyethylene = 3 gm and used plastic = 2.5 gm The results showed that using polymers made a great change in the oil recovery percent (all the oil was recovered).

The effects of temperature 30, 45, and 60 oC, rotational velocity 200, 600, and 1000 rpm, and salts concentrations (0.005 N, 0.01 N, 0.03 N, 0.05 N) NaCl + 0.0736 N Na2SO4 on corrosion of carbon steel were studied in the absence and presence of mixed inhibiting blend (SN+SHMP). Also, the effects of inhibitors blend concentrations of 600 ppm, and 800 ppm (SN+SHMP), at temperatures of 30, and 60 oC, and rotational velocity of 200 and 1000 rpm, on corrosion rate of carbon steel were studied using Second - order Rotatable Design (Box - Wilson Design) to identify the significant effects and interaction in performing weight loss studies and corrosion potential approach. Electrochemical polarization measurements were used to study the behavior of carbon steel in different salt concentrations of (CWS) with pH of 7.5 in absence and presence of the inhibiting blend. The results showed that increasing the temperature, rotational velocity, and NaCl salts concentration leads to an increase in the corrosion rate for both uninhibited and inhibited solutions. The regression model (Box - Wilson Design) that has been developed using experimental data was used to verify that the interaction term of temperature with inhibitors blend and the square term of inhibitors blend are significant for corrosion rate in 0.05 N NaCl solution while the main variables are not pronounced. Also, it is found that the corrosion rate decreases with increases in inhibitor blend concentration up to 800 ppm in 0.05 N NaCl solution. Inhibitor blend concentration of 600 ppm is highly effective giving a high efficiency in 0.005, 0.01 and 0.03 N NaCl solutions of 98.5%, 97.7%, and 96% respectively. Electrochemical polarization studies show that increasing the inhibitors blend concentration (SN+SHMP) shifts the corrosion potential to more noble value (more positive), indicating the anodic nature of the inhibiting blend used.

All over the world millions of kilometers of gas, water, oil pipelines, communication cables, power cables as well as storage tanks, buildings foundations, and many other structures are buried in the soil, suffering from soil corrosion problems which affect mainly the external surfaces of these structures. In many countries pipelines are by far the most important means of hydrocarbon transportation. This applies to the transport of crude, finished products and natural gas.It is an international problem with more structures and materials buried in the soil. The truly international scope of interest of this subject can be seen by the amount of literature and researches in this field. Attempts have been made to overcome this problem by the use of various types of techniques. The most common and applicable technique is cathodic protection.In this research a carbon steel pipe of length 100 cm buried in a wooden box submerged by soil and impressed current cathodic protection system (ICCP).was applied using power supply and electrical closed circuit, several important factors affecting the pipe protection from corrosion has been studied, like Anode position (distance and depth), soil resistivity (wet and dry), condition the pipe (coated and un - coated), distribution of potential and currents along the pipe(cathode) and the amount of current required to achieve cathodic protection.A correlation was achieved to simulate the ranges of parameters and factors affecting Impressed Current Cathodic Protection. Regression of this model to data and results yielded parameter values vary depending on the effect of the same factor.

Abstract: Nowadays speech processing methods are usually implemented in the time or frequency domain. Filter bank can be considered as a divide and conquer approach within signal processing, since large problems are sub - divided into many smaller problems. While filter banks are essential components of speech processing, and in signal processing in general, they will have the focus in present days. An adaptive filter is a filter that self adjusts its transfer function according to its optimizing algorithms. Least mean square algorithm has slow convergence when used with nonstationary signals like speech and it has high computational cost but normalization of step size (or input signal) leads to a useful variant of the LMS algorithm known as the normalized LMS (NLMS) algorithm, which gives better convergence characteristics than the LMS because it uses a variable step - size with respect to the input signal power.To improve the convergence rate and/or computational complexity and also to overcome the disadvantage of a full band adaptive filtering, a structure is illustrated that is subband adaptive filtering; this will converge faster at a lower computational cost for speech and white noise inputs.This research shows most types of subband decomposition structures and makes comparison among them based on their performance to cancel the noise with minimum computational complexity, maximum convergence speed and maximum noise cancellation with lowest delay.Moreover three new hybrid tree configurations or the tree decom - position are proposed to maximize the overall performance of adaptive noisecancellation system.They are given the abbreviations HTPSAF1,HTPSAF2 and HTPSAF3. These three systems use polyphase filter bank that has showed a noticeable increase in the convergence speed and large reduction in the computational complexity due to the lower number of coefficients that can be achieved for the analysis/synthesis filters, which in turn will result in minimum delay in the reconstructed output speech signal.The algorithm of subband decomposition structures has been described theoretically then modeled under MATLAB simulation program using built - in filters and real input signals.

Abstract: This thesis investigates the performance of some windows on the flow signals that are generated from the planar capacitance spatial filter (PCSF) according to the moving of the solid particle in the channel of the filter. The sensor that operates as non - invasive device for solid flow measurement utilizes the thin wall of a dielectric pipe section as a shielding layer to protect the sensor from erosion, rust and moisture, and to make it more versatile.The finite - difference model equations are solved using successive over relaxation (SOR) methods. The waveforms show that the response of the PCSF is spatially - biased towards particle flowing closer to the plane of sensing electrodes and that the resulting flow signal is non - sinusoidal. The SOR method that is used to compute the PCSF potential fields has been investigated using a mesh of 110 by 32 nodes, and the algorithm was programmed in MATLAB (Release 2013a) using an Intel core ™ i3 PC,CPU processor.To study the effect of the total harmonic distortion (THD) content on the flow signals that are calculated with respect to the fundamental frequency of the power spectrum density through a specific quantitative criterion, this work comprises a comparative study among three types of windows; Hanning, Hamming, and a subOptimal window called the Kaiser window.The effect of particle flying heights, relative permittivity and size on the THD of the flow signal were examined. It was found that theTHD of flow signals at heights closer to the plane of sensing electrodes is high and decreasing gradualy when the particle flying height is far above the sensor. All the three windows used in this work have better suppression of harmonics distortion as compared with unwindowed (raw) flow signal.

Abstract: While the aircraft flying above the earth surface, the signal transmitted from the satellite to the aircraft suffered from changes in it's characteristics at the aircraft receiver's antenna according to many factors affecting the direct and reflected power from the earth surface such as the distance difference, the nature of the earth surface, elevation angle, Doppler shift, etc… This Thesis introduces a proposed algorithm to analyze and simulate the communication link between the Satellite and the aircraft taking into account all the parameters that affect the magnitude of the power and signal characteristics received at the aircraft antenna. The proposed method uses the ray - tracing technique in this simulation to analyze the communication link between the Satellite and aircraft. The simulation developed in this thesis has minimized the error percentage as much as possible taking into account most of the factors that might affect the characteristics of the signal received by the aircraft from the satellite. This simulation considers the free space loss, specular reflection losses, scattering factor, earth curvature effect, etc…,also the simulation takes into account the Doppler effect that caused by the aircraft movements. The simulation measures the received signal strength and fading characteristics of satellite to aircraft communication to determine the effectiveness of communication and to establish parameters which can be useful to the communication system designer in Iraq and the rest of the world. MATLAB® v6.5 used in the simulation as application software, the simulation also applied to MATLAB® v7.0.

Abstract: Multiple - input multiple - output (MIMO) wireless communication systems have received significant attention due to their enormous channel capacity potential in rich scattering environment. Such systems need to consider multiuser transmission / reception in their design. This thesis investigates theoretically the ergodic capacity of multiuser MIMO systems operating with adaptive techniques to enhance their performance. The ergodic capacity of multiuser MIMO system is analyzed and simulated for three types of channels : additive white Gaussian noise (AWGN) channel, uncorrelated Rayleigh fading (URF) channel, and semicorrelated Rayleigh fading (SRF) channel. The downlink SRF channel for each user is modeled by assuming that the fading is correlated at the transmitter but uncorrelated at the receiver side. The simulation results are compared to those related to a single - user system and used as a guideline to present an adaptivetechnique to enhance the capacity of MIMO system operating in SRF channel. The adaptive technique is based on a tradeoff between time division multiple access (TDMA) and block diagonalization (BD).Simulation results are presented using MATLAB environment to address the dependence of ergodic capacity of a MIMO communication on various system and channel parameters. The results indicate clearly that the threshold level of angle between users ? employed in the adaptive system must be chosen carefully to maximize the ergodic capacity. The optimum threshold ?th is equal to 24°, 42° and 47°, for angle spread ? = 5°, 50° and 75°, respectively

Furthermore, there is increasing interest in using high - level modulation to provide enhanced data rate for GSM evolution (EDGE).This thesis investigates the performance of both GSM and GSM/EDGE systems operating in Raleigh fading channel. The results are reported for different models of fading channel in order to describe various environments. A detailed SIMULINK model is developed in MATLAB environment to simulate the GSM system. Furthermore, a MATLAB software package is developed to simulate extensively the EDGE system. Both simulation models are handled to characterize each essential part in these systems. The simulation takes into account channel coding, modulation type, interleaving and burst building, multipath channel effect, channel estimation, and detection process.The simulation results indicate clearly that to achieve a bit error rate (BER) of 1x10P - 5 P in additive white Gaussian noise (AWGN) channel, the signal - to - noise (SNR) ratio should be 5.25, 3.75 and 12.25 dB when GSM, MCS - 1 EDGE (GMSK modulation), and MCS - 7 EDGE (3?/8 - 8PSK modulation) systems are used , respectively. These values are to be compared with R12R.43, R1R0.21 and R2R1.05 dB, respectively, for HT100 - type fading channel. The MSC - 1 system offers the best BER characteristics followed by GSM system. The MCS - 7 offers the worst BER characteristics among the three systems.

Abstract: The implemented existing high capacity optical networks are based on 50 GHz wavelength - division multiplexing (WDM) channel spacing and carry up to 50 Gb/s data rate per channel. In recent years, there is increasing interest in using dual - polarization (DP) technique to enable future systems with at least 100 Gb/s rate per channel to operate over existing optical networks. The performance of these advanced systems can be enhanced further by using coherent optical orthogonal frequency division multiplexing (CO - OFDM) technique which offers high spectral efficiency and outstanding tolerance of fiber dispersion.This thesis addresses the effect of fiber nonlinear optics on the performance of dual polarization CO - OFDM/WDM system operating with 100 Gb/s per channel. Different modulation formats, namely BPSK, QPSK and 16 - QAM, are used. First, the performance of a single - channel system is investigated in the absence and presence of fiber nonlinearity. The results are compared with those of a conventional (single - polarization) system to identify the key role played by the DP technique. The investigation is then extended to WDM systems incorporating DP - OFDM technique. The results reveal that the effect of fiber nonlinearity can be reduced or cancelled by using optimum transmitter laser power Popt. Further, the value of Popt is a function of transmission distance,number of multiplexed channels, and modulation formats. Popt of - 11, - 12, and - 5 dBm is needed for a ten - channel DP system operating with BPSK, QPSK, and 16 - QAM formats, respectively.Simulation results presented in this thesis are obtained using OptiSystem (version 11.1) which is a commercial software package.

Abstract: Bit Error Rate (BER) and Bit Energy to Noise Ratio(?????????) performance of the 1 - D RAKE receiver without , with Space Time Transmit Diversity (STTD) and 2 - D RAKE without , with (STTD) and also without and with beamforming for WCDMA over RayleighChannel in presence of Additive White Gaussian Noise (AWGN) channel is demonstrated with purpose of making simulation of m - files developed in Matlab.Results are evaluated in terms of BER and ????????? considering the number of Base Station (BS) transmit antennas (1 - D RAKE and 2 - D RAKE receivers), and the number of RAKE fingers (1 - D RAKE receiver) and the number of Mobile Station (MS) receive antennas (2 - DRAKE receiver). The performance results of 1 - D RAKE and 2 - D RAKE receivers showed that the receivers have satisfactory BER performance and the performance of RAKE receivers is more improved by increasing the number of RAKE fingers, performance is even better when beamforming was applied.The performance results of the three receive diversity of 2 - D RAKE receiver schemes : Selection Combining (SC), Equal Gain Combining (EGC) or Maximal Ratio Combining (MRC)) of 2 - D RAKE showed that there are significant improvements in BER and ?????????performance over the 1 - D RAKE. BER of 10???? can be obtained at ????????? ? 5 dB performance with four fingers of 2 - D RAKE receiver with STTD and beamforming and MRC scheme for five receive antenna elements.

Abstract: Computed tomography refers to the imaging of slices of an object by exposing them to X - ray in different directions. Measurement of image quality is one of great importance in the field of medical applications. In applications such as CT and MRI scanning, most of the time the quality of reconstructed image is assessed qualitatively by radiologist or domain experts which are purely subjective evaluation.The FBP algorithm produces excellent quality and high performance reconstruction compared with other reconstruction algorithms. This thesis presents different projection types (fan beam geometry, and cone beam geometry) for the image reconstruction, the geometries are calculated analytically by specified 2D head phantom for fan beam and 3D head phantom for single slice spiral cone beam geometry with different ranges covering angle.In the thesis the FBP algorithm was applied with the fan beam and single slice geometries. Different types of filters (Hann, Hamming, Kaiser, Cosine, Ram - Lak, and Gaussian) are used in the algorithm and a new window filter is proposed in the algorithm. Comparisons are made between the new window and different common windows by quality measurement to get a reconstructed image with high quality and high performance suitable for the implementation of the FBP.A computer programs has been designed, written, and implemented in this work using MATLAB 7.1, for fan beam and single slice projections. Good results of quality and performance were obtained for the tomographic reconstructed image from its projection on CT scanner.
