February 2014 Economist Zubair Iqbal explains the daunting economic challenges facing Arab countries in transition following the Arab Awakening and the different trajectories stemming from those nations’ policy responses. Tunisia and Egypt provide an instructive case study: the former made hard fiscal decisions and has embraced sound economic principles and achieved broad support for a reform p...

A bilayer of uniform thickness containing a mixture of long and short lipids is simulated using a parallel hard-rod model to illustrate the effect of transbilayer repulsions between the tails of the long component. Monte Carlo simulations show considerable entropy-driven clustering within each layer. Demixing reaches a maximum at the highest packing fraction of the liquid state and decreases as...

Today, enterprise integration (EI) is still facing many problems and the crucial one is the semantic heterogeneity. This problem is not correctly addressed by today's EI solutions that focus mainly on the technical and syntactical integration. Addressing the semantic aspect will promote EI by providing it more consistency and robustness. Some efforts are suggested to solve the semantic problem ...

Dynamic and complex information security risks facing organizations are forcing them to take a hard look at outsourcing to Managed Security Service Providers (MSSPs). The potential advantage of outsourcing is to improve security levels at lower costs. Potential risks of outsourcing to an MSSP includes service quality uncertainty and the business risk of MSSP bankruptcy. In this paper we present...

The tissue engineering (TE) of dental oral tissue is facing significant changes in clinical treatments in dentistry. TE is based on a stem cell, signaling molecule, and scaffold triad that must be known and calibrated with attention to specific sectors in dentistry. This review article shows a summary of micro- and nanomorphological characteristics of dental tissues, of stem cells available in ...

Web users are facing information overload problems, i.e., it is hard for them to find desired information on the web. Hence the growing interest in named entity recognition (NER) for discovering relevant information on users’ behalf. We present a browser plug-in called ESpotter which adapts lexicons and patterns to a domain hierarchy consisting of domains on the web and user preferences for acc...

Container terminals are facing a set of interrelated problems. Container handling problems at container terminals are NP –hard problems. The docking time of container ships at the port must be optimized. In this paper we have built a simulation model that integrates all the activities of a container terminal. The proposed approach is applied on a real case study data of container terminal at El...

This paper presents a new Solid State Mass Memory (SSMM) suitable for space applications. The memory reliability is increased by using two different approaches. Firstly, memory mass fault-tolerance, with respect to hard failures, is obtained by using a fine-granularity hierarchical structure with a certain level of redundancy. A second strategy used for facing soji errors is based on Error Corr...
