Computer and Information Science , 2009, DOI: 10.5539/cis.v1n4p37
Abstract: This paper discusses about a research with the aim of investigating the potential integration of 3D GIS and virtual technology in designing and developing residential property marketing information system. The method adopted in this research is a standard system development lifecycle; commencing with the user requirements study, followed by the system design, the system development, the system implementation and finally the system evaluation. This research uses an informal method i.e. semi-structured interview, survey questionnaire and review of the existing information system to establish the user requirements. Ten user requirements were outlined alongside with the examination of four 3D integration and three virtual reality methods. Three out four methods of 3D features integration are selected for the system development. The developed system is tested using the black box and white box testing methods. The prototype system can be used by the real estate agents and property developer as the concept, framework and references for future development of a better conducive property marketing information system as well as simplifying the traditional flow of housing selection which gives positive impacts in the marketing transaction.
Analysing Power Consumption Of Different Browsers & Identity Management Systems In Mobile Phones
Md. Sadek Ferdous,Ron Poet
International Journal of Distributed and Parallel Systems , 2012,
Abstract: Currently there are many different Identity Management Systems which differ in their architectures as well as use different protocols and serve different purposes and are extensively used by organisations to provide online services. With the remarkable growth of mobile phones in the last few years, both in number and computational power, more and more users are accessing an array of online services using their mobile phones. One of the major concerns for the user of mobile phones is the battery life which is limited and tends to run out quickly. Hence, efficiency in power consumption is a crucial factor for any system when it is accessed using a mobile phone. In this paper, we analyse the efficiency, in terms ofpower consumption, of different browsers in mobile phones and different Identity Management Systems when the mobile phones are used to access online services protected by those Identity Management Systems.

Case Reports in Pediatrics , 2013, DOI: 10.1155/2013/307205
Abstract: Ultrasonographic (US) evaluation of spinal anomalies is limited. MRI is increasingly being used in the diagnosis of spinal anomalies. MRI has been able to show clearly the detailed anatomy of this rare case of type II diastematomyelia with triple splitting of the cord. 1. Introduction Diastematomyelia, also known as split cord malformation (SCM), is a congenital spinal anomaly in which there is longitudinal splitting of the spinal cord. Females are affected much more commonly than males [1]. This condition occurs in the presence of an osseous (bone), cartilaginous, or fibrous septum in the central portion of the spinal canal which then produces a complete or incomplete sagittal division of the spinal cord into two hemi cords. When the split does not reunite distal to the spur, the condition is referred to as a diplomyelia or true duplication of the spinal cord. MRI is a safe and important tool for confirming the presence of spinal cord abnormalities, when a suspected spinal deformity is detected on US. MRI clearly demonstrated the lesion in this rare case after suspecting spinal abnormality (diastematomyelia) by US [2–10]. 2. Case Report 37-week we have term female delivered by LSCS. APGAR score was 9 and 10 at 1 and 5?min, weight was 1890 grams, length was 43?cm, and head circumference was 31?cm. At birth baby needed no active resuscitation. Ten mins after delivery she developed an episode of apnea which required bagging for 2?min. Baby was shifted to NICU, connected to nasal CPAP for few hours, and then settled. On examination she had a soft midline sacral swelling in the sacral area (Figures 6(a) and 6(b)) with rocker bottom feet (Figure 6(b)), low set ear, and a small PFO with left to right shift diagnosed by echocardiography. Chest X-ray showed abnormal ribs. ultrasonography of the brain and abdomen was normal. Ultrasound spine showed double-spinal cord (diastematomyelia). MRI was done on day 4 of the neonatal period and showed the rare deformity of triple splitting of the cord. Plain skeletal survey (baby gram), US brain, abdomen, spine, and hips, and MRI brain and spines were done for the newborn and demonstrated the followings: (1) partial asymmetrical sacral agenesis with slightly deformed left sacroiliac articulation and partial hypoplasia of the left iliac bone corresponding to the hypoplastic articulating sacral segments. Only the 1st sacral segment is well developed, while the 2nd, 3rd, and 4th segments were poorly developed specially the left aspect, and the 5th segment was absent, this was associated with partially opened posterior sacral
Virtual water: an effective mechanism for integrated water resources management  [PDF]
Alaa El-Sadek
Agricultural Sciences (AS) , 2011, DOI: 10.4236/as.2011.23033
Abstract: In regions, which suffer from water shortage or potential water shortage like the Middle East, water policies and different mitigation measures are formulated. With the increasing population and increasing demand for food and drinking water with the fixed supply of water, the demand management policies have been introduced. Virtual Water has been adopted as an alternative or potential alternative water resource. In the application of the Integrated Water Resources Management (IWRM), virtual water has to be considered as a resource of water. In this paper, the practical value of the virtual water concept as well as the possibility of the application of the concept in the regional and national level are discussed. The paper emphasizes on the application of virtual water in agriculture products and virtual water trade of these products. This research concluded that, there is a possibility for the application of the virtual water concept on the national level taking into account water endowments, and other natural and social economic conditions. The virtual water strategy seeks ways to consciously and efficiently utilize the internal and external water resources to alleviate water scarcity. This, however, by no means implies that importing food is the only response the water scarce countries and regions should and can take. Other measures concerning the supply and demand sides of water management are imperative. The argument here is that the virtual water strategy should be an integral component in the whole package of integrated water resources management.
Experimental Investigation of Granular Activated Carbon/R-134a Pair for Adsorption Cooling System Applications  [PDF]
M. Attalla, S. Sadek
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.22002

The objective of this study is to investigate the adsorption characteristics of granular activated carbon GAC/R-134a pair in the temperature range of 20℃ - 60℃ and pressure up to 10 bars. The Dubinin-Astakhov adsorption equilibrium model is fit to experimental data with acceptable error limit. The pressure-temperature-concentration (P-T-X) diagram of the pair is also presented. The isosteric heat of adsorption of R-134a on activated carbon has been calculated using the Clausius-Clapeyron equation as a function of adsorption capacity. The maximum adsorption capacity was found to be 1.92 kgR134a/kg carbon at 20℃ after 1200 s. The experimental results also show that the increase of heat transfer area improves the adsorption capacity per kg of adsorber, which leads to the design of a finned tubes heat exchanger adsorption unit.

Urban EVs seem to be a good choice for cities and urban centers since their potential drawbacks are few and can be mitigated. This study reveals that having an environmentally friendly vehicle can soon become a reality if collaborative efforts are properly directed.
Urban electric vehicles: a contemporary business case
Transport Problems : an International Scientific Journal , 2012,
Abstract: In a world where energy supply security and environmental protection are major concerns, the development of green vehicles is becoming a necessity. The Electric vehicle (EV) is one of the most promising technologies that will make the “green dream” come true. This paper is a contemporary business case that encourages the immediate deployment of urban EVs. It proposes a model in which we can profit from the benefits of urban EVs namely, high energy efficiency, emissions reduction, small size and noise reduction. The model mitigates the EV potential limitations such as energy source, charging infrastructure, impact on electrical power system and cost issues. It also provides ideas to overcome the barriers of the technology application in order to speed up their commercialization. This study reveals that having an environmentally friendly vehicle can soon become a reality if our collaborative efforts are properly directed.
The Conformal Correction in the Strip Centered Coaxial Line Analysis
V. Sadek
Radioengineering , 2007,
Abstract: The presented work reports on the novel analysis of the strip-centered coaxial line. The conformal mapping method is used. For a narrow central strip a very easy conformal mapping is described that maps this structure onto the rectangular model line, but great distortion for wide strip inhibits application of this mapping in all the extent. The conformal mapping method allows to correct this fault very smartly by extension in auxiliary plane. Two different numerical models are also mentioned as comparative solutions of strip-centered coaxial line analysis. One of them is based on numerical evaluating of the Schwarz Christoffel integral, the other (in two modifications) is based on boundary element method (BEM).

Quasi-geostrophic equations with initial data in Banach spaces of local measures
Sadek Gala
Electronic Journal of Differential Equations , 2005,
Abstract: This paper studies the well posedness of the initial value problem for the quasi-geostrophic type equations $$displaylines{ partial_{t}heta+u ablaheta+( -Delta) ^{gamma}heta =0 quad hbox{on }mathbb{R}^{d}imes] 0,+infty[cr heta( x,0) =heta_{0}(x), quad xinmathbb{R}^{d} }$$ where 0 less than $gammaleq 1$ is a fixed parameter and the velocity field $u=(u_{1},u_{2},dots,u_{d}) $ is divergence free; i.e., $ abla u=0)$. The initial data $heta_{0}$ is taken in Banach spaces of local measures (see text for the definition), such as Multipliers, Lorentz and Morrey-Campanato spaces. We will focus on the subcritical case 1/2 less than $gammaleq1$ and we analyse the well-posedness of the system in three basic spaces: $L^{d/r,infty}$, $dot {X}_{r}$ and $dot {M}^{p,d/r}$, when the solution is global for sufficiently small initial data. Furtheremore, we prove that the solution is actually smooth. Mild solutions are obtained in several spaces with the right homogeneity to allow the existence of self-similar solutions.
