The research addresses the concept of dynamism and movement in architecture; also the role of time, the human's eye, and perception to classify it “latent or movement”. In addition, analyzing international projects about the thought of dynamism, and employing the vocabulary of the formation. Because of the thought of some architects in the static of the building, which gives the feeling of boredom. In addition, fixed forms are no longer able to meet the needs of users, especially with the increasing of climatic changes and advanced activities. Besides, the misconception that dynamism is only to move the building without looking for the architectural thought behind it, which depend on definite rules and the designer's experience and practice. Therefore, the aim of the research is to guide and employ the concept of dynamism in design, what governs it from the architectural thought to be interactive dynamic buildings by concluding and formulating a methodology to link and reconcile among opportunities of movement, technology “systems – materials”, the required performance, and the factors affecting. Moreover, determining any types of movement more properly and suitable for the nature of the project to root the concept of dynamism, and to give the building an architectural character.

The beginning studio sometimes described as the most traumatic period for the architecture students. Many challenges in visualizing, imagining and comprehending spatial relations over the stages of the design process have been observed. Educators confirmed that spatial ability is central to design studio demands. The main goal of this research is reducing beginners’ obstacles and enhancing design education. A total of 353 first-year architecture students were selected via random sample from three universities in Cairo. The students’ spatial ability skill-level were measured using two spatial ability test instruments. Three scores of the first design course were used in determining the students’ design performance. Inferential statistics, as well as correlation analysis and crosstab chi-square test with SPSS were employed to analyze the research data. The outcomes presented strong significant correlation at (< 0.01) points between students’ spatial ability and students’ design course performance. It has proved that spatial ability is a valid predictor of success in the beginning studio. Also, measuring spatial ability helps to identify students who are not ready for studio requirement. Findings suggest enhancing students’ spatial ability among the all preuniversity education levels and during the preparatory year course subjects. This will increase the probability of success.

The continuous growth of motorized vehicles and air pollution caused by them, are among the major reasons in which strategies related to transportation and land uses are being implemented enhancing the built environment. This paper introduces approach leading catalytic effects for urban redevelopment through introducing Mobility hubs. According to academic arguments regarding the relation between urban form, built environment and travel patterns, the more urban development around transit stations referred to as transit oriented development (TOD) is compact, the more it contributes to sustainable metropolitan system. Mobility hubs are types of TOD projects, which strive to create opportunities for development. The current research examines the possible role of mobility hubs as anchors in urban regeneration strategies aiming to formulate a model that evaluates hubs' effects on surrounding contexts‘ regeneration. This research is divided into two parts; the first examines the concept of mobility hubs as catalysts to existing urban areas‘ regeneration, the dimensions and elements responsible for the hubs' success as catalytic projects, the second investigates case study for transit station and its context, in Alexandria city, Egypt. The analysis of this case will be through designed model assessing the catalytic effect of the hub on its immediate contexts of value.

Cairo’s Downtown cinemas were once masterpieces of architecture, screening golden age movies plus witnessing important events. Nowadays, few are still working, while many are ready to be demolished. The best conservation for historic buildings is managing change caused by time. One way to make this happen is smart engaging reuse, thus continue to retain value to current and future generations. Local government and private companies have tried to resuscitate Cairo’s silver screens. This revitalization started with simple face lifting, then developed to rebranding with creative re-use introducing new functions. A key to this creative re-use is across disciplines; new forms of art, music, and media performances. This paper aims to explore four re-use performances bringing the insight of art and media into the field of heritage management. First, “Nassim El Raqs” organized “When dance meets heritage” in Theatre Cinema Eldorado. Second, Radio Theatre re-used to host liveshows; “Al-Bernameg” and “AblaFahita”. Third, Zawya - located in cinema Odeon - launched as the first art-house cinema in Egypt. Last, Teatro Independent Theatre opened their interactive performance “The Metamorphosis” at cinema Elkahira. This paper ends with a framework for rebranding cinemas; comprises both the challenges facing the re-use and proposing community-oriented marketing strategy.

Egypt is facing a huge financial problem reflected on the difficulty of funding public projects either in construction and infrastructure sectors. One of the approaches for such problem is to work cooperatively with private sectors in the form of PublicPrivate Partnership Projects (PPP). This approach, however, is facing a number of challenges. This paper, thus, aims at providing a factor analysis for the establishment of PPP in Egypt through extracting lessons learned in other countries. A literature review has been done to analyze existing factors, followed by a qualitative study of case studies. Finally, a survey questionnaire was conducted on a purposeful sample of 55 stakeholders, either from private or public sectors in order to prioritize and verify factors affecting the success or failure of PPP projects in terms of their severity and impact in Egypt. Results of this paper indicated that bureaucracy, corruption, poor enabling policies and inefficient feasibility studies are among the major barriers that face PPP in Egypt, whereas achieving a reliable contractual structure and political support are the main potentials. Findings of this paper are valuable to stakeholders, decision makers and policy makers in Egypt, as it could guide their thinking towards achieving successful PPP Projects.

In the present study, high resolution remotely sensed data (<60-m resolution) has been used to locate and track changes in urban land cover in Cairo, Egypt. Landsat (TM) images for July months of the years 1985, 1990, 1995, and 2000 have been analyzed to identify the growth of urban region at Cairo. The population growth in Cairo City during the period 1985 to 2000 and its expected rates up to 2035 have been taken into consideration. The results of the study revealed that, a real extent of urban lands of Cairo City could be monitored accurately by using a high resolution Landsat satellite images. Among the main findings is the increase of urban area of Cairo from 267.38 Km2 to 548.13 Km2 through the period from 1985 to 2000 with percentage annual ratio estimates 7%. A significant correlation between the rate of increase of Cairo urbanized area, ΔUA, and the rate of population growth, ΔPA, has been found in the simple form, ΔUA = 40.85 – 100.6 ΔPA. Therefore, if the rates of population growth and human activities in Cairo City continued, the urban area will reach to be 1193.85 km2 by the year 2035. In addition to serious local climate changes will prevail.

As time passes, the heritage buildings need rehabilitation to meet the needs of current and future generations, while respecting its heritage value. Due to the physical, functional and/ or economic reasons, heritage buildings require architectural additions while adapting them to the contemporary conditions. For this reason, that the research seeks to establish a framework for using new additions to heritage buildings, therefore these additions should be compatible for achieving a harmony with use, construction, appearance of the original building. To achieve our aim, the study divided into two parts, the principles and considerations of conservation for heritage buildings in addition to design strategies for architectural additions and their types in terms of use, construction and appearance have been included in a theoretical study. Following the theoretical an analytical inductive approach has been adopted to analyze the levels of the new additions to heritage building by examining the selected examples that linking different addition types of mass transformation. Same examples have been analytically measured by the opinion of audiences through filling a survey to show the acceptance ratios according to the levels of addition to the original building.

Two criteria of good vehicle suspension performance are typically their ability to provide good road-holding ability and increased passenger comfort. The main disturbance affecting these two criteria is terrain irregularities. Active suspension control systems reduce these undesirable effects by isolating car body motion from vibrations at the wheels. The paper describes an adaptive fuzzy control (AFC) schemes for the automobile active suspension system (ASS). The design objective is to provide smooth vertical motion so as to achieve the road-holding (with as small as possible tire deflection) and riding comfort over a wide range of road profiles. Effectiveness of the proposed control scheme is demonstrated via simulations. With respect to the optimal linear control (LQR), it is shown that superior results have been achieved by the AFC.

One of the most important problems that concern those interested in heritage is the deterioration of urban and architectural heritage in many Egyptian villages and cities. This problem is due to the rapid urbanization in Egypt which causes local and regional changes that have bad impact on the urban heritage. It is necessary to preserve the historical heritage because of its national wealth and its historical, cultural, economic and social values. Dealing with these heritage areas should achieve the balance between preserving the urban and architectural heritage and the developing sustainable tourism in these areas. One of the most important methods of sustainable development of these heritage areas is the community participation in the development projects. Therefore, the study aims to define urban and architectural heritage and conservation. It also aims to identify the role of the community participation in the different stages of conservation. It also aims to define the sustainable tourism development, its strategies and its relation with the heritage areas. The study analysis local and international examples of heritage areas to identify the most important problems and their solutions. The study ends up with conclusions and recommendations and a suggestion on sustainable tourism development of heritage areas.

Local scour around bridge piers and abutments, induced by hydraulic deficiencies, is the major cause of bridge failure. Most of the available empirical formulae have been developed based on experimental laboratory tests using uniform sand. However, the bed sediment in the field is to some extent graded. To develop a more reliable formula, well graded sand was used in the experimental flume of this study. In the present paper, the local scour depth around exposed single pile founded in sandy soil was studied experimentally in the laboratory to predict its maximum value. New scour depth prediction equations were developed and compared with some of the previous published equations, other researcher's data, and field data and they were found in very good agreement with them. For complete definition of the scour hole geometry, new equations were developed to estimate the scour hole width at different locations around the pile, thus helping in introducing protection measures for the scour hole. The developed equations are applicable for both clear-water and live-bed scour cases.
