Abstract: ان الصفائح المثقوبة تستخدم عالميا في تصنيع الھياكل في التطبيقات الميكانيكية والانشاءات كمثال على ذلك ھياكل الطائرات والتراكيب الطبية ووصلات الربط الخ. ومن المعروف جيدا ان استعمال الثقوب في الھياكل المجھدة تولد اجھادا موقعيا عاليا في منطقة من الثقب تعرف بم | The plates with holes are used in cosmopolitan for manufacturing structures in mechanical and civil engineering applications like aircrafts, medical structures, joint connection applications etc. It is well known that utilizing holes in stressed structures produces highly localized stresses at area of the holes known as the stress concentration area,which leads to reduce the mechanical strength of the structures.The main objective of this study is to investigate the effect of three parameters on the stress concentration factor in plate with two holes having different size holes and subjected to uniaxial tension. The three parameters include firstly, the location of holes when oriented with respect to axis of loading, parallel, transverse and inclined with line of uniaxial tension load at different angles. Secondly, the aspect ratio for the hole size (large to small radius).The last parameter effect is the distance between two holes.Numerical simulation using finite element method for two - dimensional model is developed to determine the maximum value of Von Mises stress with commercial software package ANSYS V.11.The experimental photoelastic technique is carried out on fabricated polycarbonate model loaded in one direction. From the analysis of the results, it is found that the maximum stress concentration factor is at the point tangent to the edge of the hole. The comparison between the finite element method and experimental photoelastic technique results showed the stress concentration factor, which obtained experimentally and with finite element method are congruent, since the maximum variation between the two results is about 7.03% As well as the highest and lowest value of the stress concentration factor equal to 3.1973, 2.0640 at value of angle 60°, 90° respectively.It is recommended from the above conclusions that manipulating the three parameters which effect the stress concentration factor are namely, holes position, size, and distance between two holes on the plate that used in the application will play essential role to reduce the value of stress concentration factor which subsequently crucially minimize or avoid fast failure. This can be translated into saving precious lives preventing money wastage due to structures damage ending into catastrophe.

Abstract: في الوقت الحاضر , تحظى مكائن القطع المبرمجة باھمية كبيرة في المعامل والورش التصنيعية بسبب دقتھا العالية ومرونتھا لكن لسوء الحظ لا تزال ھذه المكائن غير قادرة على التاكد من جودة السطوح المنتجة. الاتجاه نحو اتمتة عمليات القطع سير للحاجة الملحة للحصول على ج | Nowadays, computerized numerically controlled (CNC) machines have high importance in manufacturing factories and workshops due to their high accuracy and flexibility. Unfortunately they still cannot ensure the quality of machined products. The trend towards automation in machining has been driven by the need to maintain high product quality with improving production rate, these improvements can be possible by monitoring and control of machining process. In this research a vision based monitoringsystem was introduced for the on - line direct automated measurement of the cutting tool flank wear width based on a new algorithm on the basis of canny edge detection and morphological operations for the captured images.Twelve specimens were prepared using STARCHIP CNC turning with four cutting speeds (57,98,110 and 125 m/min) and three depths of cut (0.5,1 and 2 mm) and constant feed of (0.04 mm/rev). Maximum and minimum absolute error and error percentage in the maximum flank wear width was (0.058,0.002 mm) (9.7,0.54 %) respectively. The results show the effectiveness of the proposed method in the monitoring of the tool condition.Also, Vision based monitoring system was proposed for the measurement of tool nose wear which have direct interaction with the workpiece during machining. Measurement operation is done by comparing reference and worn tool images; the algorithm is composed of image preprocessing, Otsu thresholding, conforming method for the exact alignment between the two images and image subtraction is performed in order to detect the nose wear area. Morphological opening by reconstruction was used to remove isolated foreground pixels result in due to the quantization errors. The maximum and minimum error percentage in tool nose wear area (6.72,0.48 %) respectively; the experimental results show that nose wear occurs after the flank wear exceeded its maximum standard limit in roughing operations Keywords : tool wear, flank wear, nose wear image processing, automated visual inspection, tool condition monitoring.

Abstract: تعد سبائك الالمنيوم - سليكون والتي تحتوي على التيتانيوم احدى المواد التي تتميز بمقاومتها للبلى كما بينت الدراسات والابحاث العلمية ذلك.في هذا البحث تم صب سبيكة المنيوم - 7% سليكون وبنسب مختلفة من التيتانيوم (0.5 , 1 , 1.5%) وتحت معدلات تبريد مختلفة في قال | Aluminum - silicon alloys that contain Titanium can be considered one of the wear resistant materials and attract several researchers recently.In this work ,Al - 7%Si alloy with different percentages of Ti ( 0.5 , 1 , 1.5% ) was poured under different solidification conditions into the metal mould.All prepared alloys were dry slided under different bearing pressures ( 5 , 10 , 15 , 20 , 25 N ) on the steel counterface surface using pin on disk wear apparatus. Optical microscope and scanning electron microscope (SEM) were used to study the microstructure and determine wear mechanism of Al - Si alloys respectively. On the other hand , X - ray diffraction technique (XRD) was used to determine the phases that were present in the matrix of Al - Si alloys.Microstructural analysis and X - ray diffraction showed that two phases are presented in the matrix of Al - 7%Si alloys.These phases are ? - aluminum and eutectic and three phases are present in the matrix of Al - Si alloys that contains Ti. These phases are ? - aluminum ,eutectic and titanium aluminide Ti9Al23.Significant refinement occurred for ? - aluminum, eutectic and titanium aluminide Ti9Al23 phases when using metallic mould cooled with cold water in comparison with heated and unheated metallic moulds Hardness was increased with increasing Ti percentage and with increasing the severity of solidification condition used.Remarkable changes in the wear rate occurred for Al - Si alloys during dry sliding in which the magnitude of wear rate was dependent on the Ti percentage ,load and solidification condition used.Design of experiment (DOE) was used to optimize the effect of process variables ( load and Ti percentage) on the wear rate under different solidification conditions using computational statistical software (Mintab 16).

Abstract: في هذا البحث تم تحضير المواد المركبة النانوية اساس معدني (A356/Al2O3) باستخدام تقنية (rheocasting) ومن ثم تم اجراء عملية التشويه على الساخن عند درجة حرارة °250 م.في البداية تم صهر السبيكة A356 في درجة حرارة °730 م بعدها تم تبريدها الى درجة حرارة الشبه ص | In the present work Al2O3/A356 nano composites have been prepared using rheocasting technique, the nano composites were then processed using hot deformation at 250 °C.Firstly A356 matrix alloy was melted at about 730 °C, the superheated molten alloy was allowed to cool to the semi - solid temperature at 600 °C, then Al2O3 nano - particles with different size (10,20) nm and different weight percentages (1 and 2)%wt were added inside the vortex formed due to stirring , hot deformation carried out with different ratio 30% and 40% at the temperatures of 250 °C and strain rates 0.1 s?1. The produced nano composites samples were characterized using optical and scanning electron microscopy ,X - ray diffraction , hardness test and wear test using pin on disc apparatus. The results of microstructural observations showed that the Al2O3 nano particles cluster mostly near the grain boundaries and form a band surrounding the grain boundaries. The dendritic structure of ? - Al phase is fragmented and the ? grains became more uniform and smaller than their corresponding as - cast 356 alloy. On other hand the microstructures of nano - Al2O3/A356 composites after casting and hot deformation at 250°C, showed modification of ? - Al and Si eutectic. The columnar dendrites ? - Al phase changed to the nearly equiaxed grains or globular morphology. The results of hardness test showed that the nano Al2O3/A356 composite were exhibited higher hardness than the as - cast A356 alloy The nano - composites hardness, increase with increases the size and increases in weight percentage of the Al2O3 nano - particles, and with increasing percentage deformation. The result of wear test showed that the hot deformed nano Al2O3 /A356 composites have greater wear resistance compared with hot deformed A356 alloy. Furthermore, with increasing the particle size and the percentage of Al2O3 nano particles, wear rate will decrease. The results also revealed that the optimal results was achieved at the nano - composites containing 20nm Al2O3 particles after hot deformation with 40%. SEM studies of the worn surface of nano composites showed that the main wear mechanism was oxidative in conjunction with metallic wear.

Abstract: لسبائك الالمنيوم عالية المقاومة طيف واسع من التطبيقات من صناعة السيا ا رت الى الصناعات الفضائية.ان السبب الرئيسي وراء النمو السريع للطلب على هذة السبائك هو مزيج من الخواص الفريدة التي جعلت منها واحدة من اكثر الت ا ركيب والمواد الهندسية استعمالا، ولذلك ل | High strength AL - alloys have a wide spectrum of applications from automobile to aerospace industries. The demand for these aluminum alloys grows rapidly because of the unique combination of properties which make them the most versatile of engineering and construction materials. Hence, development of high strength Al - alloys continues to be an important area of research.In this work, the influence of different heat treatments on the mechanical properties and fatigue life under low cycles of wrought 7075 aluminum alloy was experimentally investigated. The heat treatments included peak ageing (T6), over ageing (T73) and annealing (O).The effect of heat treatments on the alloy was explained in terms of their influence on the mechanical properties. The results showed that T73 temper has an ultimate strength of 504.7 MPa and elongation of 12.5%. Peak ageing treatment enhanced the strength by 10.9% and reduced the elongation by 7.2%, while in the annealed condition, the strength was reduced and the elongation was improved by 51.33% and 31.2%, respectively. T6 had the highest hardness followed by T73 and O tempers.The flat fatigue specimens were subjected to constant reverse bending load. The tests were performed at the laboratory environment with a frequency of 23.3 Hz and at a stress ratio (R) of - 1. For each temper, strain - life graphs were obtained for specimens with notches in the form of central cylindrical holes made by drilling. The fatigue resistance of specimens with notches was compared to the results for notch - free specimens. It was observed that the presence of a stress raiser, such as a drilled hole, lowers the fatigue life for all tempers. However, the notch sensitivity of the fatigue life was different for each temper.The fatigue crack growth rate of T73 and annealed temper was investigated, the results showed that T73 treated sample exhibits higher crack growth resistance. Paris` equation was derived for each temper Keywords : LCF. precipitation hardening. 7075 aluminum alloy. fatigue crack growth.

Abstract: Under the increased technical advancement occurring to about all of the life aspects and specially architecture, It’s no longer for the traditional facades to be able to keep up with the advanced user’s needs and to meet the functional performance and requirements on the environmental, ecological, social and aesthetical aspects, and here it became a necessity to develop another options that would be more efficient in the provision of those requirements, so a new generation of buildings have appeared called “Smart Buildings” or “Intelligent Buildings” with there sophisticated parts and various details, one of those essential parts is the “Intelligent Façade” for it’s being the essential and primary defensive line for the building against the environmental and climatic variations, in such an advanced high performance manner, and for that importance and essentiality of this specific part the research took it as it’s particular study topic, where it has reviewed and discussed a number of general studies on the façades in smart buildings, and many of a specific studies belonging to organizations and competent casts that have addressed the issue of intelligent façades in their projects, which their discussions produced an identification of a knowledge gaps and thus let to the crystallization of the research problem : “Lack of clear and organized knowledge concerning intelligent facades in buildings, so as they would be effectively adopted by the designer in creating such facades in his designs, or the possibility of developing ordinary existing facades on the Arab and local level”.Thereby determining the aim of the research by : “Present the most organized and clear knowledge concerning the intelligent facades in buildings in a manner that enables the designer to effectively adopting them to design or develop existing facades generally, in order to serve the existing of the Arab and local experience in particular”.To achieve such goal, it has been a necessity to adopt an analytical and descriptive approach for the previous knowledge and take a sequential researching steps, the first step was to build a comprehensive theoretical framework by defining the intelligent façade, down to abstracting three main vocabularies of the theoretical framework represented by : integrated intelligent façade design, intelligent façade techniques, and effective response, and represent them in a graphical form.The next research steps focused on applying the vocabularies of the theoretical framework on the elected Arabic and local projects that have been adopted the matter of intelligent and responsive façades in a matter that servers the research goal, which took over the design of facades where great attention had been paid to constituently try these experiments to achieve sustainability and energy conservation, and introduced virtual perceptions around them and determine the type of measurements, and data collection, and according to that the results would be analyzed and discussed down to put the final conclusions related to the theoretical framework in terms of the importance of the presented knowledge which enables the architect to be aware of the various aspects of designing intelligent facades and enables him to keep up with the technological advancement and development occurring to it in a way that makes it easy to adopt through his various designs, as well as conclusions related to the outcome of the case study on the other hand, which have shown the limited adaptation of the elected local projects to the intelligent façade techniques where active response had been limited to the environmental, visual and aesthetic aspects, in limited interacting capacity compared to the achievements of the elected arab projects, and accordingly have been identified a set of general recommendations related to an investment of the presented theoretical knowledge in development of visions and orientations of academic and professional fields to develop a forward - looking vision of a renewable local architectural ideas of sustainable and in line with the spirit of the age to be accepted and supported by the investors and beneficiaries, as well as specific recommendations of the possibility of developing and modernization of the existing facades of local buildings (represented by the elected projects) exclusively toward intelligent technologies that are effective response.

Abstract: تعد المباني التاريخية شاهدا على ذاكرة المدينة وارثها الحضاري، وعنصرا مهما في تشكيل هوية المكان وتميزها الحضري، اذ شهدت الاونة الاخيرة تزايد الاهتمام بهذه الابنية بشكل عام، وبالاخص في التوجهات المعمارية والحضرية المعاصرة بشكل خاص، والتي ركزت على استغ | the historic buildings are witness to city memory and its cultural heritage, and an important component in forming the identity of the place and distinguish the Civilized, As recently has seen growing interest in these buildings in general, and especially in the architectural and Civilized modern trends, Where trends focused on the exploitation of the historical value of the building and ensure their participation effectively in the Civilized and economic development projects, and try to achieve a balance between preservation projects; Whichprovides the continuity of the city's identity and cultural distinguish, and between tourism investment projects, which provides modern requirements of both the place and the community and tourists, in order to convert these buildings to a link provides continuity between the past, present and future. Also subjected such a civilized outcomes in many countries of the world to policies that have investment objectives, economic and cultural through tourism, which has become recently manufacture have goals and the fundamentals and strategies lately. As the most of prior knowledge in the field of architecture on the tourist side focused on the descriptive side of the inherited cultural visits by identifying the nature of the historic building or archaeological terms of design, construction materials, details and many other aspects, and visits by clarifying the guidelines and instructions for dealing with such buildings, according to governmental and international organizations such as UNESCO laws, and once through the tourist promo description that focuses on specific aspects of such sites, shows that the knowledge needed to investigate methods for the manufacture of historical tourist spaces and shape and structure within the overall fabric of the historical center.At this point the importance of research had appeared in the necessity of creating holistic imagine about how to activate the role of the historic Space within the various tourist ranges in cultural tourism manufacture projects in historic buildings in different classification, and through the study of the tourism manufacture in the historical buildings and the role of each other, and how to deal with the historic buildings within the laws international and local legislation and restrictive covenants critique of modern requirements for tourist investment, and how to initialize historical Space function as tourism.Research problem identified in the "lake of a holistic knowledge framework about manufacture historical Space tourism and it integration."Research aims Justifies to "build a model for structuring historic building as a tourist space integrated and effective in general first, and determine the model of the behavior of the tourist catalyst movement in the tourism Space secondly" through research hypothesis which states that the integration of structured domains and the elements of tourism retaining in the historical center increases the effectiveness of tourism Space "hypothesis" the behavior of the tourist movement in the tourism Space depends on the strength of stimulating tourism elements.basis of that, method selected and consisting of several stages, first phase build a comprehensive conceptual framework for manufacture historic tourism space where the developed items derived from prior knowledge and restructuring to be distributed in four main items, that is : (the concept of tourism Space, restructuring of tourism Space, the behavior of the tourist movement in Space of tourism, manufacture the historical tourism space), Second phase, Applied procedures and building the default model for manufacture space tourism in historic buildings after testing active indicators extracted from the conceptual framework of this model represents all levels of manufacture space tourism in historical buildings which are divided among four major ranges, that is : (range A : centered historical tourism, rang B : the historic center of tourism, range C : historical of tourism decade, range D : core historical of tourism).measurement method and it manner has been identified by focusing on 2 main items to be application in (restructuring of historic Space tourism), (tourist movement behavior in the tourism Space) as well as identifying the elected sample that will be applied, that contains two sample, the first is (new Hassan Pasha historical center / Baghdad, Iraq) The second is (Topkapi Palace the historic tourism center and its nearby / Istanbul, Turkey).The third phase, is specialized to discuss the results, analysis and validation of hypotheses, were identified final conclusions presented in two topics, the first topic on the results of the application, while the second topic is particularly the final conclusions of the research, as it focused first topic of the results of the application for restructuring tourist space and elements of tourism ranges in historic buildings and increasing the effectiveness of space tourism at achieving higher integration in the structure of space tourism ranges and the tourist elements that retaining it.As well as the results from the questionnaire about the tourist movement in space tourist who intended to stimulate the tourist movement and expand tourism within historical areas through organizing and designing of the tourism spaces and distributing it to historic buildings and decades activated and invested tourism, The second topic of the results has focused on the role of international conventions to guide tourism intervention in historic buildings levels as well as the conclusions of the property in how to design a tourist spaces within the historic environment and modern approach her to meet tourist requirements of the local community and the place at the same time through an integrated tourist space and activated.

Abstract: اهتم الباحثون بمختلف توجهاتهم لدراسة المورفولوجيا الحضرية؛ لاهميتها في صياغة النسيج الحضري للمدن ومنها المدن الدينية بمختلف المراحل الزمنية، والتي تعكس التسلسل الزمني لتكوين البنية الحضرية للمدن، تعاملت الدراسة مع المورفولوجيا الحضرية من خلال متغيراتها، و| Researchers with their various orientations have been interested in studying urban morphology; for its importance in framing urban fabrics for cities including religious cities on various time stages, which reflects time sequence which forms urban formation for cities, the study have dealt with urban morphology through its variants, as well as with urban formation as one complete formation including both physical side and incorporeal side, research confirmed that the effect of religious factor in religious cities shows in religious monuments, for what it has of regulatory role that works on of the urban fabric’s cohesion, and that role stands out from studying regulatory relations of the urban formation, this is very clear when looking closer at the urban appearance, which differentiates from one city to another through the relation between its morphologic variants, depending on the type of creation factor. All that have determined the research problem : that is the lack of informations about the regulatory role of the religious monument through the variant morphologic stages of the urban fabric’s cohesion of Samarra, the research depends on studying the urban formation as a historical morphologic study for its most important time stages those through which the urban fabric had passed, and determining the most important power centers (religious monuments) which regulates the urban formation, and emphasizing the synthetic properties for clarifying the effect of the religious monuments on the urban fabric’s formulation for religious cities including the Arabian Islamic city in its variant morphologic stages, to verify research’s target in showing religious monuments’ role in the regulation of Samarra’s urban morphology according to the impact that they have as regulatory element for the urban fabric, showing a practical definition for the urban morphology have been a must that it is “the structural appearance for cities, whether they were small or big, including plans, fabric, land uses and the ways which depending upon the appearance’s study have been done, which express the appearance of cities on variant historical stages”, as well as a research methodology that includes construction of informative fundament for the urban morphology and its influencing factors, which divided into formation factors of fabric and ideological proposals which represents the new foundations of cities’ regulation, and laying a clear vision for the research problem, as well as showing reviews of previous studies, with determining the most important methods of morphologic analysis, also the informative fundament includes notion studies for the city from the Islamic perspective through determining Arabian Islamic city as one of the religious cities, and studying its urban fabric and its planning elements to access the definition of religious monument’s notion, and determining Samarra city as a (case study), defining it and determining its religious monuments and its morphologic stages (chapter one and chapter two), then research have drawn theoretical framework’s elements for urban morphology and determining measurements of structural properties (regulators) including both global and local ones for the religious monuments to verify research hypothesis that have been formulated as that “religious monuments have a role in morphology regulation of Samarra City and its fabric’s cohesion”, depending upon that, essential planning have been prepared to analyze the chosen sample (Samarra city), as well as applying measurements and drawing the conclusions (chapter three and chapter four), then research have drawn the final conclusions and recommendations (chapter five). Conclusions have shown the role that the religious monuments have been performed as a regulator for the morphology of urban formation through the regulatory properties (structural) including both global and local ones for its spaces in its various morphologic stages, as well as it have afforded values of indicators for the chosen area that are certified for future development projects to maintain the religious monument role in framing and cohesion of Samarra’s urban fabric.

Research seeks to clarify the sustainable urban development, its concepts, its importance and its components by submit it as a general problem for research, Waters' canals represent as one of the development elements, so The specific problem is " the canals don't be considered as an important component of sustainable urban development of the city." if we consider the canals as natural legacy wich inherited from the current generations to the futuristic generations. Previous literature indicated that it didn't include the study of the role of waters' canals in the morphological urban development for the cities ",this represents the main problem of the research.The aim of the research is to study the waters' canals in Basrah city, diagnosis and specify the role of canals which embody the greatest importance in the morphological urban development of this city. The main research hypothesis is "canals vary in their importance or their role in the morphological development of the cities through their spatial organization or lands uses on the both sides of these canals ".The research followed the analytical method, and put a comprehensive theoretical framework for each of sustainable urban development, waters' canals and urban morphology and Sustainable urban design. To test the hypothesis research through study the spatial organization of Basrah city by using the Arc View GIS 3.3 to see the canals that deserve rehabilitation inside the city. The coaxial map was plotted for the network of the main streets of the city which are parallel to the waters' canals and research assumed that the integrated axis is reflected on the water's canal and thus refers the integration of that canal and it has importance in the morphological development of the city , which must rehabilitated later. Study lands uses which align the important waters' canals by field survey. Do aquestionnaire to professionals to measure words of sustainable urban development and sustainable urban design.The research reached in its practical study to diagnose the main waters' canals in the city which have the more importance in the morphological development of Basrah city , where its result come from the integration and the access to those canals by using major ways of transportation.The results of the program are about twelve canals which gained high values, those canals are " Sarraji Canal , Al Khora Canal , Alashar Canal , Alkhandag Canal , Rebat Canal , Jubailah Canal , Shatt al - Turk canal , the vertical canal on the Shatt al - Turk canal , Baghdad's streets' Canals beside Aljameyaaat district , the canals which paralleled Baghdad's street beside Alsma'i and Alaaleya districts ,alsheeaba's drainage canal and the vertical canal between Al - Sarraji and Al - Khora Canal) ,the research diagnoses and concentrates on the main lands' uses on the Both bankes of those Canals and they are (governmental , commercial and residential and mixed).

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.

Abstract: Imprint is considered as a language during the last four decades. contemporary studies had presented this trend through different approaches which delt , primarily ,with identidy as semantic expression in all events, the aim was to create continuity and links with social structures which represent the vessel contains human culture.hence; there was a strong need to verify various methods that extend the space surrounding continuity context. Therefore touch methods are clearly important as an indicator in suggestive and expressive ways.the imprint doesn’t react individualy unless it is used through the logic of dialogue. This meant that touch is atool of semantic ideas which depends on formalistic expressions using interpretive dimension of imaginativevisions to create designer special that imprint specific to him signs that form a constructive texts which meet collective agreement and represent an individualistic quality of its own. This approach requires a presentation of knowledge which is concerned with continuity.By defining the touch and reviewing available of this aspect in order to create a viable approach to it, the research is discreeted towards utilization of touch as one stage of strategies to achievebcontinuity in contemporary architecture.Various studies we've reviewed which delt with social and expressive dimension as well as methodogical approach. the research area was narrowed down to.studies delt with architecturer's persortality throught his touch on his design , as though studies that analys his proudection ccording to his surrounding area. The aim of this research was to reveale theoretical vision that describes.The theoretical content of this research has identified three elements of significance to this problem(imprint form, the characterizes of the imprint, and imprint aim).Unperfectlly understanding to imprint as atheme generally and don’t enable it take important position in architectures specifically.By this we define touch's work as a way to express about the architecture him self alone which depend on two aspect on of is Hypothitical depends on understand touch from the designer , and the other one is shape aspect which try to make connection between the imprint and the designer personality in aime to creat expressional dialogue delt with recipient continuouity from aside and from the other side understanding the hidden messeges that have sent through imprint.Application of the theoretical presentation considered for first one aspect(out of three). Hypothitical consideration suggected singular change for the first one aspects and binary change for the last two aspects. Measurments methods was developed to determine change and applied to selected sample to determine readings intellectual and formal levels. General and specific methods were reviewed with the aim of exploring the stated hypothesis. The first results and findings were presented regaring three fields. The variability of the framework , the results of measurements and finally general consideration of the wholenesof the approach. Recomandation were presented and fields of further reserchs where identified.

Abstract: ادى تطور التكنولوجيا الرقمية الى توسيع القد ا رت التصميمية لدى المصمم المعماري وخاصة في مجال توليد الاشكال المنحنية وذات التعقيد الشكلي والتي اتصفت بعدم امكانية او صعوبة القدرة على تنفيذها بالطرق التقليدية للبناء مما ادى الى ضرورة البحث عن طرق واساليب جدي | The development of the digital technology has led to the expansion of design capabilities of architects, especially in the field of generating curved forms with formal complexity which was unattainable with the traditional methods of construction, thus resulting in the need to research for new executive ways and methods to realize them physically, and so Digital Fabrication has appeared in architecture as a contemporary concept that grew over the past two decades. 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.

Abstract: شكلت تغيرات نمط المسكن الحضري في العراق خلال القرن السابق اساسا لاشكالية في قدرة واجهته على توفيرالخصوصية البيئية والاجتماعية والتعبير عن هوية البيئة المحلية.وبنقد التوجهات الاساسية لحل هذه الاشكالية والمحددة بتحليل التكيفات الواقعية للنتاج السكني او درا | The basic changes of urban residence pattern in Iraq during the previous century have formed a foundation for a basic problems in its elevation ability to provide the social and environmental privacy and expressing the distinguished identity of the local environment. Through the criticism of the trends which try to solve this problem and which can be determined in analysis the real adaptations of the residence unit and by extracting data from the real residential production, or the specialized research studies which may prepare the necessary indexes to develop, a reference is made to the weakness of what has been presented by both directions in this aspect due to the change of the balance of the properties of the resident needs in the elevation increasing towards some apparent items of self needs in a way that explain the weakness of the ability of real production affected by these trends to create the suitable adaptability to realize other needs despite of its importance. the study also points out the weakness of these studies which tried to solve these problems by independently focusing its various items from the input of its extracted induces in the residential reality whether because of the disagreement of these items or the contrast of its indices with the priorities of real residential needs or the indices of its realization.On these bases, the study suggested a compromizing mechanism that depends on presenting the indeces that can realize the balance between realizing different needs of residence and the priorities of resident wills in the elevation based on an approach that depends on the use of the potentials of both real and research aspects in presenting its special indices and to examine the ones presented in the second aspect.The suggested mechanism, therefore presented its approach within a group of procedural steps depending first on extracting the indices of the residential reality. Being a representation of the resident wills and his priorities , these indices are compared with those extracted from the realization of different needs of residence.The results of the comparison can express the ability of research aspect on presenting its indices applicable in the residential reality whereas the deference may point out the extent to which the vision varies towards the priorities of residential need of the mechanisms of their realization between the two aspects and the ability of the residential reality to create its own indices by its own realistic mechanism and priorities. It also express the styles that can be adopted to inhance the efficiency of the research aspects in this respect. To practically test the suggested mechanism, it has been applied in the urban residential production in Mosul according to the prepared approach where the extracted practical conclusions showed the efficiency of the mechanism in extracting the realistic indices to realize the different needs in the residential reality and the effecting changes. The study also showed the limits of contribution and the evaluation of the architectural role whether in practical design or in research supporting studies in supplying this production with the additional indices to develop the residential production and the factors of success and failure in their role. The research concludes with some recommendations which focused on activating the cooperation between the two mentioned aspects and the role of architectural design in practice as an active joint capable of inhencing the transfer of indices between the two parties.

Abstract: 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.

Abstract: ان البحث يمثل جزا من المحاولات الجاريه على نطاق القطر لتوظيف بيانات الاقمار الانوائيه في الطقس حيث تم اختيار منطقه الشرق الاوسط لاجراء البحث لانها تمثل منطقه كبيره وواسعه ويظهر فيها العراق.بيانات الاقمار الانوائيه المستخدمه في هذا البحث تشمل صوره فضائيه | This research represents part of the current on country attempts to employ metrological satellite data in weather and change forecasting using contour model. The region that was selected for performing the research is Middle East region because it’s great and wide region and includes Iraq. Remote sensing information that is used in this research includes satellite image data taken from Meteosat satellite. ERDAS package is used to produce the contour model on satellite images.Satellite weather images for three sequence days were taken and operated on, active contour models were classified. These phenomena represent clouds in different types. This type of contour is fast and easy to create as well as discover the clouds edge more accurately. Accordingly contour intervals that are 30 gray level are found to detect accurate features in images.The other part of the research classifies contour models to many classes to discriminate clouds type and clearing the type according to color,that found in image. Where a low cloud represents high color value and refer to dark color. This refers to the contour line classified according to color degree from 0 to 240 gray level, compared the satellite image that was taken from practical experiment with others to find the changes in images and the results are clear.
