المستخلص: يتناول البحث موضوعا مهما وهو التتابع التاريخي للطرز العمرانية العراقية ضمن فترة منتخبة , تم اختيارها وفق اسباب واهداف محددة , يشق البحث طريقه ببناء اطار نظري يعزز قاعدته البحثية والسببية مستدلا منها على المشكلة البحثية مؤسسا بذلك لهدف واضح مهم ومن هذا الم | This research deals with an important subject which is the Historical Succession of Iraqi architectural styles, within a selected period of time. It is is concentrated on establishing a theoretical framework in order to enhance the research and causality base, relying on the problem of the research, which focusses on the un clarity of the architectural styles of this important period.The research moves to explain the most important points and concepts.Starting by analyzing the previous studies which give us a classifies the research in the Succession of the styles for the period that the thesis have chosen, (The Abbasied period and the invasion of Al - Mongols and Othman ) since (280A.D to 1336 A.D).This leads the search to a main goal which is, to discover what is the commons and different and highlighted the effect of each one one the other. In the second part of the first chapter , it highlights the theoretical framework on the most important previous studies that dealt with the history and styles to know the ways that did not deal with the subject of the similar history as well as the most important methods that can be used as means to bring out such research , it also focus on the very clear knowledge gap that is represented as the basic problem of the research. "That the method of Succession could fill the gap of the concept for the study of styles within the different eras".The second chapter starts with a try to understanding the concept of styles and the path that is pursued through time and the changes which happened in its concepts. Assuming that the "Succession "could be a great tool to Investigates the styles for the periods that took place in our research. So, it has been the definition for the essence of the Succession and its potentials in finding architectural styles facts. Third chapter , is concerned with determinating the selected period of the study and the reasons for selecting , this period is characterized with "The late Abbasid which synchronize the Covenant Seljuk and Al - buehi in addition to the occupations of the Mughal and Ottoman".As the research deals with both of the analytical method and the comparative method in analyzing the historical periods with a choice of study samples (install location) with tracking these places across the time. So, the search in analyzing the style must depend and take more specialized direction for the purpose of diagnosing of formalism and precision ties to study the properties of the shape and the key elements of each historical era with the study of the elements of architectural profile in addition to the properties of architectural styles.this third chapter and the fourth chapter are based together on the analysis of examples of indicators that have been inferred in the second quarter for the conclusion of what is continued of styles and what is based on n demonstrating the impact of each one of them for what followed.

المستخلص: الابنية التاريخية … هي نتاج فكر وثقافة الانسان وهي المعبر الحقيقي عن حضارة الامة وتراثها الفكري، وبما ان الشعوب تعرف عن؛ طريق ثقافتها وحضارتها فان العمران هو المعبر عن خصوصية المجتمع والتي تكونت نتيجة تفاعل عوامل مختلفة اجتماعية واقتصادية وبيئية وغيرها , | Historical Buildings … are result of human thoughts and culture, also considered to be the substantial entrance to nation’s culture and its intellectual heritage. Considered that nations have been always known and studied through their culture and civilization, it is reasonable to state that architecture is an important entrance to understand privacy of specific society that have been formed through an interaction among social, economic and other aspects. Today, there is an immense and clear interest in human intellectual and artistic heritage, including those architectural and urban heritage. That is why this heritage - whether it goes back to a near or far time - is getting a special interest among others, because they are considered to be an entrance to study human existence, past, memories from specific time. As a result, it is considered to be his identity that shows human existence. Consequently, to protect that heritage is immensely important for what it is worth. Also, today, it is clear that technology evolved much further than anytime, and it is crucially important to collect all available data, as it plays an essential role and has a crucial effect on our present, and future.Accordingly, It is clear how crucially important to think in a certain way to deal with those building, to protect, revive and work to improve its sustainability and convenience by using advanced techniques and technologies, also to measure how suitable it is to beingpreserved by those techniques. Consequently, reaching to a reasonable and clear method to achieve its preservation and to preserve its historical and various properties. Although, thesis which have dealt with preservation are replicated, those which are general, they have dealt with the problem by using urban filling and renewal or traditional preservation’s methods. Whereas, those other private didn’t consider to adapt a clear method for preservation that achieves coherence and cohesion. As a result, the general axis for the research is identified with : The existence of informative gap in the current method of urban preservation, while the research’s problem is the lack of clarity in the informative knowledge that should be available to achieve the protective preservation (Sustainable) for architectural heritage. Accordingly, that shows the research’s target clearly, that is to identify suitable advanced methods to achieve the protective preservation (Sustainable) for architectural heritage. The research has stated its thesis : Preservation of historical and heritage architectural buildings depends on its capability to suit current and future requirements of society, and to balance the system of forms and values inside the urban scenery and to support it, as well as its capability to success economically and environmentally through using those building functionally.The research depends on analytic and descriptive method, which includes forming an informative theoretical framework about the historical and heritage architectural buildings, preservation, protective preservation (Sustainable) and to brief most important variables and indications for each term. Accordingly, the research has conducted that preservation of historical and heritage buildings is related to design in the first place, and it is possible for creative thoughts and techniques to vary according to the design vision. And analyzing those thoughts within functional variables, as well as temporal and spatial enriching have shown that whenever taking a decision for a functional change, the new function turns up with clarity and purposely, which comes with a clear program and undergoes to the protective preservation’s terms when preserved and directed. In all those buildings who have been preserved, especially the ones designed by famous architects, an advanced reliable techniques have been used, which confirms the protective preservation.When it comes to economic aspects, cost of conduction and sources of investment, the tourism and meaningful attraction as well as how well those preserved building function offer an additional sources of investment as well as the meaningful and iconic aspects which confirms its role in sustaining the building.

Also, thorough studies in the field of material properties, their specifications and inherent technologies, as well as their practical applications, are scarce.Based on these findings, the problematic of this study could be expressed as follow : there’s currently a lack of appropriate directed studies in the field of new construction materials, their use and their integration in architectural vision, based on a sustainable view, as well as the use of contemporary technology.So it has been developing a specific content target : 1 - The provision of general frameworks to solve the problems and challenges faced by the specialists at the use of new building materials.2 - provide a complementary theoretical and practical specifications for new building materials and environmental characteristics, functional and aesthetic effects in sustainable architecture knowledge.In order to address the stated problematic and reach the established goal, one hypothesis have been formulated : To address the problem of the research and achieve its objectives has been the development of research hypothesisas follows : (Technological development of new building materials contributes to draw the path towards sustainable urban environment, as the new and advanced structural materials and techniques used were able to create sustainable architecture achieve environmental, functional and aesthetic requirements) In order to test these hypothesis and assess their veracity, a theoretical framework was established, based on the following methodology steps : - The study of intrinsic relationship between architecture and building materials, starting with mud and stone buildings, then approaching other specific local and temporal architectures such as marshes buildings, the ever‘moving forward’ architectures of the successive industrial revolutions, the modernist movement in the beginning of twentieth century, sustainable architecture, and the new architecture of the third millennium. - The theoretical study of new building materials, their specificity and characteristics in the light of the latest evolution and development of sustainable architecture. The emphasis would be on smart materials and nanoparticles, as well as their potential. - The practical study of these materials and their effects when actually used in construction, while focusing on three aspects : environmental, functional and aesthetic. For that purpose, eight giant buildings which integrated new building materials, located in different environments, and performing different functions, were analyzed. The aim was to finduseful indicators for comparative analysis. - These three aspects (environmental, functional and aesthetic), were applied and studied on modern, local buildings,everyone performing a different function. Questionnaires forms were used, which were distributed to specialists in the field. It appears, after analysis of the answers in regard to the three aforementioned aspects, that the environmental aspect had the most positive impact, immediately followed by the functional aspect, then the aesthetic aspect, which comes last.

It has evolved over the years with the stability of its content where it is essential.The evolution of the concept in the contemporary architecture refers to the importance of the recipient and his reading of the text and architectural diversity of various aspects of Appropriateness such as (function, expression, economy... etc.). From this side the importance emerged to study the concept of Appropriateness and to identify its branches and aspects.the general problem of this research was about “Appropriateness in architecture”. The subject has been emerged in the linguistic and scientific studies so as in architecture to branch out several types and aspects which necessitated narrow down the search.Search been reduced to one type of Appropriateness which is expressive Appropriateness in products of architectural and the study identified the contemporary buildings because the importance of the concept in the current buildings.Research problem Identified as “Lack of a comprehensive objective perception about the concept of expressive Appropriateness in contemporary architectural production and the relationship between the designer intentions and the other indicators of special conceptThe study identified a procedural definition of expressive appropriateness as a "compatibility and degree of proportionality between designer intentions (expressionistic ideas to be delivered to the recipient) with what actually verified in the final product where productions vary in their suitability for designer intentions. Hence the aim of the research is to form an objective and comprehensive framework for expressive appropriateness properties and how they are invested to achieve the goals that are supposed expressive presence in the production and measure the achievement of goals expressive on elected projects for practical application.The hypothesis of this research has been Formed as expressive appropriateness actually realized in the architectural production through compatibility between intentional designer in output expressed goals and what Verifier in production, which depends on private recipients readings, as the designer intentions means goals plus the results of indicators to achieve expressive appropriateness ". The research found the existence of diversity in expressive goals for designers with a variety of mechanisms and realized Systems and configurable characteristics used in production. It was also found the presence of expressive appropriateness between the goals of designer and the receiver reading in varying degrees Key words : appropriateness, Expressive appropriateness, the goals of expression, intentions of designer, contemporary architectural production.

The research has aimed to find a mechanism to adapt the methodology of contemporary inputs, as they are considered factors of impact on urban identity , the city's heritage Urban (particularly residential) requirements of modernity down to consistency and balance in the structure and appearance of this urbanization. To accomplish these goals in order to solve the problem, the hypothesis has been put in the research and is represented as follows, ( The main hypothesis : - The traditional urban identity of the Iraqi city it is only the implications of several interaction of combination of factors such as : ideological, religious, cultural, political, social, and economic......, which has : innate presented by the student Rokia Basim Khaza'al durability and deep - rooted heritage). The secondary hypotheses ,they include (The secondary hypothesis (first), Contemporary input into the decisions of urban residential structure which produces the problem of alienation of the identity of the city in general and the identity of the modern urban residential specifically for the Iraqi city. But the Second hypothesis (II) , Urban residential characteristic which is in consisting with consistent balance between stability factors (features and characteristics of the cultural heritage), and change agents (of modern inputs, which include economic, sociodemographic, religious, cultural, political, legislative and technical, which showed a big difference between recent data and the presentinputs, which necessitated the emergence of new indicators that restore the correct status of our sobering heritage with new flavor.The research has approached an analytical method by dealing with fresh ideas and new theoretical concepts so as to reach a practical balance between tradition and modernity in the modern Iraqi city be, on other hand , the study has to crystalize , elaborate and translateit into practical indicators through determining the affecting variable diagnosis affecting on the likelihood of changing Iraqi urban identity in general and the structure of urban housing in particular. So the research has involved chapters, the first one is dealt with the basic concepts of identity and characteristics and the levels of all types and the determining the identity of the city reaching to , the identity of the home and find out the qualities and features of the urban where the Iraqi city received through the old housing and modern one as well as to be so close to the characteristics of each of these concepts , in order to develop and crystalize the research hypothesis, then , the research enters Chapter II beginning to define the changing and influencing input components exclusively on urban residential identity , through mentioning to the social factors - demographic, economic, and religious - cultural and political - legislative and technical, and to mention to each factor of them in general. Then the research enters Chapter III illustrating the mechanism of impact for each factor on the identity of the residential urbanization by taking aspects and details and varieties of each particular factor and how it affectson the details that can be attributed to the urban identity of theresidential city especially through the building materials , techniques, planning and handling of interfaces and finishes and sizes and masses of urban, After that , to reach the Chapter Four , the practical chapter of the research , it includes the application of the theoretical framework of indicators on a residential district within the city of Baghdad, which involves several shops.The practical study has relied on two levels, the analysis of research and study to identify through the distribution of a form on different samples by comparing different periods, in order to reach an order to compare the results between the old urban and its nature of identity with modern construction and clarify the change that happens on the housing to reflect the reality of urban civilization to create the urban identity of the Iraqi city.Finally , for the purpose of finding recent findings and reaching to by studying the theoretical and field results of the questionnaire to the most important recommendations of the research, as well as areas for future research and the beneficiaries of it. Finally , the research has reached to results represented , most notably, in the role of community with its individuals in changing by not attention to the legislation and controlling Urban, which were reflected by the excesses that caused random and in the absence of the identity of the residential urbanization.

Despite the emergence of a number of theses that tried to explain it in the field of architecture, none of them gave this concept a comprehensive definition or dealt with it in depth, hence the concept of (digital fabrication in architecture) appeared in a general framework that recognizes the concept and its beginnings in the other fields and the stages it went through to reach the field of architecture, for the purpose of reducing the limits of research to the specific frame which is summarized in(the role of digital fabrication as a link between the design process (modeling) and the realized architectural product which is represented by the fabricating of building parts, and by thorough searching of studies which took into consideration the existence of the above - mentioned three - way relationship between (designing, fabrication, and production), the research problem was derived, which states that (Lack of previous knowledge in forming a comprehensive conception describing how to achieve digital fabrication and its impact in contemporary architectural production) and thus to reachthe goal of the research (creating a comprehensive conceptual framework regarding how to achieve digital fabrication in the field of architecture and its impact in contemporary architectural production), and achieving this approach requires the construction of a theoretical framework consisting of four main units; The methods of fabricated digital design generating, Digital fabrication techniques, production strategies and to clarify its impact in contemporary architectural production, and as such is the first phase of solving the research problem. While The second phase deals with application procedures marked by the formulation of hypotheses and consisting of two main assumptions (the realization of digital fabrication depends on the integration of the levels of each of the following, the methods of fabricated digital design generation and digital fabrication techniques and production strategies) The second premise is (the adoption of Digital Fabrication with its three levels affects the contemporary architectural product positively) and then determining the basic requirements for the application by selecting the method of data gathering and the type of measurement used as well as defining the application sample marked by a range of contemporary global projects by some of the best architects who rely on digital fabrication in the production of their buildings and which are executed in the real world and belong to the same era which is the last five years and has a similar functional approach for the purpose of highlighting the formal and structural aspects.The third phase, focuses on discussing the results, analyzing them and determining the validity of the hypotheses and then defining the final conclusions which were raised in two axes, first axis focused to clarifying the effectiveness of the theoretical framework in achieving digital fabrication and its role in bridging the gap between representation and construction and its impact in the product that was achieved within the formal, structural and professional aspects, while the second axis focused on the conclusions drawn from analyzing the results of the application, which indicated the possibilities and special effects that distinguish each one. And so the research has contributed a cognitive addition to the field of architecture and defined recommendations and future horizons forpossible researches keywords Digital fabrication, ,digital design methods, digital techniques, digital.

المستخلص: Since the building envelope represents the main axis for all thermal controlling processes being the insulation of internal environment from the external one, and as a responsive and adaptable with the external changes through its thermal conduct by preventing external effects.In addition, it includes all the external means that ensure comfort for occupants represented by walls, roofs, grounds, and all vents (doors and windows) whereas the external walls represent one of the most important structural elements that have a direct effect on the thermal performance of the building.In order to achieve the aim of the research the experimental approach and style of analytical study were adopted. The current study included two main aspects : first, the theoretical side : Which included the time delay factor calculation and cooling load depending on the Radiant Time Series (RTS) theory that achieve accurate and detailed results and ease of application The theoretical results for each hour were calculated using a new version of Mat lab program. While the second aspect included the practical test and measurement where three test chambers have been constructed as samples for the purpose of study located in the department of the mechanism and productivity of Al - Fao Engineering in Altajiat in Baghdad. The three chambers were constructed with dimensions (3000mm x 2250mm) and (2250mm) height without windows and the ceilings and walls were made the only effective resource in changing the level of thermal comfort inside it. The longest side of the three test chambers was directed towards the east - west. The walls of the first chambers have been made of perforated brick , the second chamber of thermo - stone, the third of double glazing units. The ceilings of rooms were treated by materials of humidity contraindications with thermal insulators are quite similar in order that the comparison would be only confined to the walls, and to identify the effect of the air cavity (100mm,25mm) when using it with the different materials of cladding such as ( white marble, black marble, stone of Ba Athra, composite - panel).Two iron structures were made in order to exchange the termination materials and the thickness of the cavity as well as each chamber has been equipped with (one ton) air conditioning with a same cooling degree for each chamber, the devices were connected by a scale to measure the amount of energy spent in each chamber with a fixed temperature inside, in addition to thermal sensors fixed on the inner and outer surface of the wall and in the inner space, consequently the energy exchange was considered as an evidence and indicator to the differentiation among the materials used and types of cavities in double walls. The theoretical and practical results made a good rapprochement, whereas the first test chamber (in which Brick is the material construction of the walls) has made a contrast ratio between the theoretical calculations and practical application for the electric power about 23.6%, while the second test chamber (in which thermo - stone is the material construction of the walls) has made a contrast ratio for the electric power about 22.3%. Consequently, Results of the study showed that the Exterior cladding material by using perforated brick of 120 mm thickness recorded the highest proportion of the economy in the amount of electric energy which considered to be the best thermally. However, Exterior cladding material (such as black Marble) and cladding materials with fewer block (such as composite - panel) represent the worst thermal performance because they made the lowest economic proportion of the amount of electric power. Besides, the thermo - stone material as a material of walls constructing has made an economic ratio of electric energy higher than the one made by the 240mm thickness perforated brick. The research, As well as, concluded that increasing the thickness of cavities from 25mm to 100mm may reduce the consumed amount of electric power about 6.6% when the construction material for the walls is 240 mm thickness perforated brick and 4.3% when the construction material for walls is thermo - stone.

ZnO has high breakdown electrical field, also has a much larger saturation velocity. In this work three ultraviolet Metal Semiconductor Metal (MSM) photodetectors were fabricated, based on ZnO and Silver (Ag) doped Zinc Oxide (SZO) with (2% and 4 % doping ratios) thin films. The technique used to prepare the thin films was sol - gel and spin coating technique by using Si (100) p - type. Silver interdigitated (IDT) electrodes were deposited on the films by a vacuum coating deposition technique to form the three devices.The electrical properties for the fabricated photodetectors (PDs) were studied using Semiconductor Characterization System (SCS) at room temperature ( 27 C^o). The applied voltage was in the range of ( - 5 to 5) V.The SEM images showed a non - uniform distribution of the Ag dopants, these dopants formed clusters and these clusters increased as the amount of Ag dopants increased. The mobility, carrier concentration, and roughness for the SZO films increased when compared to undoped film. The optical bandgap and the transmittance are decreased when the doping ratio is increased. The saturation current (I - S) was decreased by a factor of 4, and 12 for the devices based on Ag doped ZnO (with 2% and 4 % doping ratios) thin films, respectively. The sensitivity was significantly increased with increasing the doping ratio. This enhancement attributed to the roughness of the Ag dopants (clusters). The detectivity was increased for the devices based on SZO films. The high detectivity with low saturation current made the devices based on SZO films suitable for optoelectronic applications and integrated circuits. From the experimental data and analysis, it was found that the PD with ZnO : Ag 4 % doping ratio has higher responsivity and gain of 0.523 A/W and 257 , respectively. This is confirmed by thin film and device characterization which makes this PD suitable for UV detection purposes.

In this work, Extended Gate Field - Effect Transistor (EGFET) pHsensors were built using thin films of Zinc Oxide (ZnO) doped with Palladium (Pd) as sensing membranes. The Pd - doped ZnO thin films with different molar concentrations (Pd = 0%, 2% and 4%) were deposited onto p - type Si(111) substrate by sol - gel method. The surface morphology of the prepared films was imaged and studied by Atomic Force Microscopy (AFM) and Scanning Electron Microscopy (SEM). The crystal structure of the fabricated films was examined by X - Ray Diffraction (XRD) test. The optical and electrical characteristics of the films were measured using spectrophotometer and Hall - Effect measurement device, respectively.The EGFET pH - sensor has been prepared by linking the fabricated sensing devices to the gate terminal of a commercial Metal - Oxide - Semiconductor Field - Effect Transistor (MOSFET CD4007UB).The fabricated sensing devices were immersed in buffer solutions with pH range of (pH 3 ? pH 11). The pH sensing characteristics of ZnO and Pd - ZnO/silicon EGFET devices were studied using Semiconductor Characterization System (SCS - Keithley 4200).The ZnO EGFET sensor exhibits voltage sensitivity and linearity of 31.5 mV/pH and 0.9809 (or 98.1%) in linear regime with pH range of (pH 3 - pH 11). The voltage sensitivity and linearity of Pd - doped ZnO (with 4% molar concentration of Pd) EGFET device in the linear regime with pH range of (pH 5 - pH 11) are 27.86 mV/pH and 0.9785 (or 97.85%), respectively. The experimental results show that the Pd - doped sensing films by sol - gel method cannot be adopted for whole pH range. This means that the doped films have fewer amounts of H+ ions sensing sites at its surface than undoped ZnO fims.
