It is well known that three quarters of the world contain saline water. The saline water contains amounts of salt dissolved in water to a concentration of parts in per millions (ppm) includes sodium chloride, Sodium sulfate and magnesium sulfate. Compaction of Base coarse layer is usually done by water which is considered tap water. Cites near shores often need coastal roads to act as service roads parallel to shore lines. For this matter, the use of saline water in compaction is considered a main objective in this situation due to the decrease in transportation cost of Tap water used in hauling and compaction of base coarse layer. This research studies the effect of saline water on the mechanical properties of the unbounded granular material used in base coarse layer. The study compares the results between the use of saline water and standard tap water by subjecting both samples to different lab tests such as California baring ratio (CBR) and modified proctor. The results showed that saline water could be used successfully in the operation of constructing base coarse layer with good results concerning the amount of absorbed water content and maximum dry density of the base coarse layer which will result in good compaction. In addition, the CBR test results showed high evaluation of strength for samples contained saline water. The study used Dolomite material for base coarse layer from Jabal Ataqa as one of the most used aggregate types in Egypt through construction.

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.

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.

Currently, any industries face higher competition in their business pertinent to the customers’ demands and product design requirements. Customer requirements and satisfaction measurement can be achieved through various methods. This paper presents an integrative framework of Kansei engineering (KE) and Kano model, applied to a product (light bulb changer LBC). KE captures and translates the emotional needs of the customer (Kansei), whereas Kano model is inserted into it to investigate the relationship between service quality attribute performance and Kansei. On this research, the integration between KE and KM in product development approach is applied though a daily life product as a case study (LBC product). The results show that the mechanical mechanism consisting of spring fingers with pvc, round grip and plastic telescopic pole is preferred by customers. This study found that the perceived or quality attributes are influenced by the emotional design or Kansei response. It provides the useful spectrum to other researchers to gain more powerful product development in the future, and stay on the customer satisfaction and requirement track.

Fracture in the adjacent levels is one of the consequences to the use of commercial poly methylmethacrylate (PMMA) bone cement. Modified PMMA with a reduced Young’s modulus was found to be safer for cancellous bone augmentation procedures. The aim of this research was to study the effect of adding hydroxyapatite (HA) nano-particles and acetone on different properties of PMMA cement. A commercial PMMA cement was used as a model for bone cement. Three groups of modified PMMA/nano-HA were investigated by adding 2, 4 and 6 wt. % of HA. Acetone as a porogen mixed with distilled water in different amounts (A/W: 1:1, 2:1.5 and 2:1g) was used to produce porous PMMA cement. The residual monomer, polymerization and mechanical properties under tension and compression tests were investigated. Young’s modulus detected from compression test decreased from 826.5±10 to 728±66 MPa by adding 6wt.% HA. Adding acetone to PMMA with 2:1.5g (A/W) has decreased the compressive Young’s modulus to 753±38 MPa. High Performance Liquid Chromatography (HPLC) measurements were carried out with intervals of 2 hours, 6 hours and 24 hours to evaluate the residual monomer for all groups. The amount of residual monomer has decreased after 24 hours of curing by adding acetone and nano-HA. Modifying PMMA by HA and acetone have inconsistent effect on the polymerization temperature. It was concluded that HA and acetone can be used to reduce the stiffness and residual monomer with enhanced biocompatibility of the commercial PMMA bone cement.

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.

Coal mining and washing activities in South Africa often lead to the generation of fine and ultra-fine coal which is in most cases discarded due to high handling and transportation costs. Studies conducted revealed that a large quantity of these fines have market acceptable calorific values and lower ash contents. In order to reduce fines discarded, processes have been developed to re-mine and process the fine coal discards with the aim of improving the calorific value, adding them to coarse washed coal to increase the yield as well as pelletizing the fines so as to meet the market specifications in terms of size. The goal of this study was to evaluate the efficiency of fine coal washing using gravity separation methods and comparing the products thereof to the market specifications with regards to the calorific value and the ash content. Coal fines from the No.4 lower seam of the Witbank coalfield in South Africa resulting from a dry coal sorting plant were subjected to a double-stage spiral test work, heavy liquid separation and reflux classifier test work respectively. The reflux classifier achieved products with low ash content and an increased calorific value, at high mass yields. At higher fluidization water flowrate, the reflux classifier performance was superior to that of the spirals with products of lower ash content and higher calorific value. At low cut point densities, heavy liquid separation yielded the cleanest products with very low ash content but at much lower mass yields. As the density increased, the mass yields increased with the ash content while the calorific value decreased. Most of the products from the different processes met most of the local industries’ specifications but none of them met the export market as well as the gold and uranium industry specifications due to the high ash content.

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.

Due to the exponential growth of E-Business and computing capabilities over the web for a pay-for-use groundwork, the risk factors regarding security issues also increase rapidly. As the usage increases, it becomes very difficult to identify malicious attacks since the attack patterns change. Therefore, host machines in the network must continually be monitored for intrusions since they are the final endpoint of any network. The purpose of this work is to introduce a generalized neural network model that has the ability to detect network intrusions. Two recent heuristic algorithms inspired by the behavior of natural phenomena, namely, the particle swarm optimization (PSO) and gravitational search (GSA) algorithms are introduced. These algorithms are combined together to train a feed forward neural network (FNN) for the purpose of utilizing the effectiveness of these algorithms to reduce the problems of getting stuck in local minima and the time-consuming convergence rate. Dimension reduction focuses on using information obtained from NSL-KDD Cup 99 data set for the selection of some features to discover the type of attacks. Detecting the network attacks and the performance of the proposed model are evaluated under different patterns of network data.

The system behavior is simulated using MATALB-SIMULINK.

Creativity has been assigned to the design or drawing, with materials most often being specified as a result of design rather than being considered a driver of it. Designers empowered by new technology now consider form as it is defined by identifiable systems. This evidence based, parametric methodology is a response to two decades of digitally-derived projects, often produced simply for their novelty. The best work results when the architect has combined respect for the old with a skilled progressive command of the new. Material culture is portrayed as the physical confirmation and articulation of a culture in its relics and design. In the time that we comprehend the thought of material culture not just as having importance for investigations of the past. yet in addition getting a projective limit. we may now be at a critical defining moment. As computation starts to significantly change our origination of the material, so in architecture this will defy the set up connection between the procedures of design and the physical fabrication of the constructed medium . Obviously, computation was brought into design & architecture the greater part a century back. furthermore, expanding digitization has since plagued all parts of the field . As though, it has remained emphatically impacted by the theoretical isolation of the procedures of design and making that has overwhelmed structural plan thinking since the Renaissance, and it is just now that creators are starting to deal with the computational void as never again disconnecting from the physical domain.

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 “seyh” 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 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.

Surface textured and DLC coated (hydrogenated amorphous carbon) samples were assessed for their coating performance at 40 oC, 80 oC and 125 oC. As a result, textured a-C:H DLC demonstrated higher but stable coefficient of friction (COF) at high temperatures as compared to un-textured DLC samples. However, textured DLC samples showed higher wear resistance compared to un-textured DLC coating. The enhancement can be elucidated by the lower graphitization of textured DLC samples.

This paper investigates an experimental study on reducing stress acting on buried flexible pipes by using expanded polystyrene (EPS) geofoam techniques. An experimental model was carried out with dimensions depending on pipe diameter (D) and location, the used fill cover material was from sand and EPS blocks either embankment form, or within sand backfill as embedded layer. The pipe flexible is un-plasticized polyvinyl chloride (UPVC). A series of experiments have been carried out by using static surface loading on rectangular steel plate,where the load is distributed over the backfill. The behavior of sand backfill around the pipe was observed, and the displacement and strains of the pipe were measured. The experimental results showed that the embedded layer of EPS geofoam block embedded in sand for different techniques reduced the deformation of flexible buried pipe, with high efficiency and low coast compared with EPS geofoam only. The results reveal that, the most effective methods thatcanreduce the stress on buried flexible pipe with low cost were EPS encasement block with head void method, and EPS block embraces the upper part of pipe method.

New trends of interior architectural design aim to maximize available spatial space for flexible and futuristic interiors. Therefore, the design of a facility structure with its fixed and movable interior components can have a significant impact on human performance leading to efficient interaction with surrounding spatial spaces. Interactive design is constantly proves creating memorable connection and empowering connection with beneficiaries’ participants that can come to life in many forms, one of these many facility structures is implementing the interior architectural design approach of "Kinetic Technology". Interior architecture is the design of a space inside any building that can be fixing. In addition, it can be the initial design and plan for use then later redesign to accommodate a changed purpose, or a significantly revised design for adaptive reuse of the building shell. Generally referred to as the spatial art of environmental design, form and practice, interior architecture is the process through which the interiors of buildings are designed concerned with all aspects of the human uses of structural spatial spaces. Therefore putting simply, Interior Architecture is the design of an interior in architectural terms. The paper presents variety approaches of innovation trends, that utilizing multiple kinetic applications for the scope, benefit of interior design elements. It will give valid benefits to interior planners and designers for efficient enhancement into their practical expertise. That experience will be achieved when implementing this technology of kinetic approach to achieve effective utilization of interior spatial spaces as dynamic quality of the spatial space’s changeable size, continuity and to create a feeling of connectivity through the spatial space, which seems to virtual enlarge the small floor area.

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.

Public authorities and governments in many countries tended to allocate to the private sector the operations management of existing PPP projects and for financing new projects. There are a lot of benefits from following this approach for all parties. These benefits included risk mitigation, cost savings in governmental expendures, service improvement, employment opportunities, and enhancement in economic indices. This approach was called public-private partnership (PPP). This term was defined as “a cooperative venture between the public and private sectors, built on the expertise of each partner that best meets clearly defined public needs through the appropriate allocation of resources, risks and rewards.” (World Bank, 2016) Public-Private Partnerships (PPP) projects become an important methodology for governments of both developed and developing countries, as a result from crucial role and their worldwide use. The PPP methodology enables public authorities and governments to allocate risks to different parties especially the private sector. According to the World Bank report the private financial participation in Egypt has accounted $219,229.82 Million in the period from 1990 to 2000. This figure has increased to $998,667.36 Million in 2015. (World Bank, 2016) PPP projects are usually more difficult to implement than other traditional procurement models because of their complexity and that their nature and their long duration. Previous research studies on several PPP projects showed that a number of problems exist in the project returns. Additionally these researches show that there is a need for an objective, reliable and practical return assessment model for PPP projects. This required model will help decision makers to assess the profitability of PPP projects at their early stages. To apply PPP projects in Egypt successfully, one of the fundamental requirements is to perform and implement a comprehensive analysis of Return on Investment (ROI). To do that analysis, it should include the factors affecting the ROI relating the projects’ influences such as; financial, legal, political ,social, etc.

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.

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.
