Demand Side Management (DSM) results in energy consumption reduction accompanied by lower cost according to the feasibility study for each project. In Egypt, DSM projects are scarce due to lack of good studies proving their underlining profitability. This paper studies the major types of DSM programs and their availability to be executed in Egypt. Tips to measure feasibility for these projects are given using the Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI), Payback Period (PP) and Discounted Payback Period(DPP). Different factors affecting the projects to study like the inflation factor and the discount rate are studied. This paper also investigates a new sustainable way for natural illumination called the sun tunnel. This method is presented with its different types: rigid and flexible as a case study.

The octane number of gasoline is one of the most important measures of gasoline quality to predict accurately the octane ratings of blending gasolines. This measured on a scale that ranges from that equivalent to isooctane (octane number of 100) to that of n-heptane (octane number of zero) octane no is effected by the saturates, aromatics, and olefins contents of gasoline. We take it as a standard and measure octane number by comparison with this standard. The accurate octane blending method will optimize the blending of gasoline components, when gasoline components are blended together, we will calculate the octane number of the blend with different octane number of the component or if the four components are of equal octane number. The blend octane number may be greater than, equal to or less than that calculated from the volumetric average of the octane numbers of the blend components, which indicates nonlinear blending. Blending would be linear if octane number of a blend was equal to that predicted by summing the octane numbers of the components in proportion to their concentrations. In practices, the discrepancies between the octane numbers of blends and the linearly predicted values have been correlated by specific empirical equations and these have been used to correct the linear predictions.

Upper Bahariya reservoir is one of the big productive reservoirs in the Western Desert (Egypt). It is characterized by high degree of heterogeneity. So, it is very important to characterize it accurately for improving its recoverable oil. Different tools were used to accomplish this task. These tools include Dykstra-Parsons coefficient, Lorenz coefficient, well correlation, hydraulic flow units, relative permeability and capillary pressure. Dykstra-Parsons coefficient (permeability variation factor) and Lorenz coefficient were determined for Upper Bahariya reservoir and found to be 0.86 & 0.92 respectively. This reveals that this reservoir is extremely heterogeneous. These results are proportionated with the pressure readings and the open hole logging format. The hydraulic flow unit’s reservoir technique showed the reservoir can be divided into nine flow units. The relative permeability curves of the reservoir indicated that it is a water wet system while the capillary pressure curve looks like a transition zone due to its high heterogeneity and high connate water saturation.

The Mevlevism order was established in the Seljuk period in Anatolia in the thirteenth century. After the death of Mevlana Celaleddin-i Rumi, his son Sultan Veled systemized his father's thoughts and created his own rules and brought the rituals to a ceremony in the form of sema ceremonies. Sultan Veled gave the name “Mevlevism” to his sect and was called “Mevlevihan” to his Dervish Houses. Nearly 140 Mevlevihane building was established in a wide geography which its east is in Tabriz (Iran), west is in Pecu (Hungary), north is in Gözleve (Ukraine), South is in Cairo (Egypt) and Mecca in Saudi Arabia. Nearly 80 of these Dervish Houses remained in the Republic of Turkey. After the declaration of Turkish Republic, these Dervish Houses were closed in 1925 by the law of “closure Tekkes and Zaviyes”, no. 677. There are two kinds of Mevlevihan, which are “Asitane” and “Zaviye”. Mevlevihan called Asitane are the main Dergahs which are full-fledged and has removing “ordeal” possibilities. The number of Asitane constructions is around 15 in all Mevlevihan buildings. Another Mevlevihan building is Zaviye. Zaviye were ruled by Mevlevi, who has the title of “şeyh” and “dede”. Many of the Mevlevihan become a historical monument because of their architectural style and construction date. However, most of these structures have been ruined over the years. Apart from a small number of Mevlevihan, which was established as "Külliye", "Semahane" parts of these Mevlevihan were used as mosques and remained up to date. When the architectural programs of the Mevlevihans are examined, it is seen that the Mevlevihans, which were settled down in 13th century have an architectural program after the 16th century and they take Konya Mevlana Dergah as an example. However, it is not possible to mention about same sized and specified spaces in all the Mevlevihans. There are similar sections only in the large- scale Mevlevihans which are “Asitane” status. In this study, an evaluation and classification study was carried out on the architectural formation of the Mevlevihans one of the Dervish constructions in Islamic architecture which attracted attention with its wide geography.

The present research presents an intelligent fuzzy logic controller (FLC) system for control water level of nonlinear systems, whereas the cross-section area of the vertical water is not constant (conical tank). The mathematical model of the conical tank level system was derived and its simulation runs were carried out by considering the FLC. For comparative analysis, a similar test runs were also carried out by means of conventional ZN based PI-mode. Interestingly, the results illustrate that applying the FLC system in the control loop in the conical tank system could provide a good tracking performance than that of conventional PI model.

Kuwait is facing a current construction boom with projects worth of more than USD188bn. The huge infrastructure spending plan of Kuwait is reflected with a growing demand of concrete as concrete is the most commonly used building material in the local construction. At the present, the quarrying of coarse aggregate which is a main concrete constituent material is banned in Kuwait since 1997 and construction industry depends on the imported coarse aggregates from neighbouring sources such as United Arab Emirates and Iran. Kuwait is also interested in challenging the growing concern of an effective environmental management of water, land and atmosphere to achieve a sustainable civilization. The increasingly environmental pressures coupled with the limited available economical resources are causing the decision making authorities to consider the practice of recycling and waste utilization. This paper presents Kuwait Institute for Scientific Research (KISR) efforts to investigate sustainable sources of coarse aggregate for construction industry from waste. The first sustainable source investigated is the production of synthetic lightweight aggregates utilizing combinations of argillaceous indigenous and waste materials, and the second is recycled aggregates from construction and demolition wastes. The potential of the two sustainable sources of construction aggregates are presented and the needed steps for real industrial application are addressed.

The paper concerns the influence of time and strain-rate effects on the clays in one-dimensional consolidation under constant effective stress. An improved creep constitutive model is deduced, by analyzing the stress-strain theory developed by yin and sekiguchi. Treating the sample as a single system and applying the boundary conditions at the system level, differential mathematical equations to the consolidation problem of clays are obtained. The proposed differential mathematical equations have advantages in their ability to (i) not clarify the primary consolidation and secondary consolidation deformation. The error in calculating consolidation deformation which is caused by the argument about end of primary consolidation can be avoided. (ii) obtain the model parameters easily. How to achieve parameters by experiment is described in detail in the paper. (iii) be programmed and solved readily for the finite difference description of the problem. Results from clays have been used to examine the validity of the model. It is shown that the proposed model can describe the consolidation of clays well.

The Arab architectural identity is characterized by the originality of the various Arab cultures. Islamic culture is what makes Arab societies unique and it is what inspired Arab architecture. Consequently, the Arab architecture encounters contemporary challenges. If modern architectural trends influenced Arab civilization, it could then obliterate its identity over the years. Moreover, positively interacting with modern architectural trends must take place rather than negative interactions. The aforementioned reasons leave this phenomenon the subject of discussion and research and thus the lack of update and development of the vocabulary of Arab architecture. The proposed study discusses the problem of the correlation of deconstructive architecture with the architectural and Arabic identity through the end of the 20th century until 2017. In order to arrive at the definition of the philosophy of deconstruction architecture and the appropriate relationship between it and the Arab architectural identity, the study utilizes a qualitative descriptive methodology that tries to give a generic image of philosophy and characteristics. Deconstruction architecture attempts to link the positive aspects of architecture and Arab identity through the analysis of the frameworks of this philosophy of particular architectural works of various architects who adopt this philosophy of architecture. Responding to the above, the current study shows that it is better to strip the modern trends and take what suits the Arab culture.

For transient stability analysis, the rotor dynamics of the induction motor have to be included. These dynamics affect the system stability when severe disturbances hit it and cause frequency deviations. For large systems, frequency deviations are small. However, it may cause loss of synchronism and break the system into smaller areas. Motor loads are sensitive to system frequency deviations. Any change in the grid frequency, changes extremely the slip. This follows by changes of the motor torque and the motor speed. The demanded active and reactive powers change as well. Natural frequencies of induction motors is considered a unique property has a great effect on its behavior during different operation conditions. This work presents the performance of the induction motors through different power systems. Based on time domain simulation models study the natural frequency of induction motors, their response in normal and abnormal operation is analyzed to illustrate the dynamics associated.
