[Review of] Sameer Y. Abraham and Nabeel Abraham, eds. Arabs in the New World

This book is a collection of sociological essays on immigrant Arab communities in the United States. It is divided into three sections: the first provides historical background to the flow of immigrants from Arab countries; the second is devoted to case studies of Arab communities in the Detroit area (where the greatest concentration of Arab-Americans in the United States is located); and the third provides a useful bibliography of current scholarship about Arab-Americans

Study of the skin effect in superconducting materials

The skin effect is analyzed to provide the numerous measurements of the penetration depth of the electromagnetic field in superconducting materials with a theoretical basis. Both the normal and anomalous skin effects are accounted for within a single framework. The emphasis is laid on the conditions required for the penetration depth to be equal to London's length, which enables us to validate an assumption widely used in the interpretation of all current experimental results.Comment: 4 pages, 2 figures. arXiv admin note: text overlap with arXiv:1507.0333

Competency Assurance Management System: Enhancement of Assessment and Verification Process

The paper addresses Competency Assurance Management Systems (CAMS): design, developing and implementing of learning programs. Competency Development Framework (DFW) skills profile of a specific job consists of set of components: competencies, levels of proficiency, and Performance Criteria -Behavior Indicators. To implement CAMS DFWs successfully, the learning development programs need to meet the SMART principles. One of which is to be measurable through mapping real work tasks to a specific Key performance Indicator(s) and achievable through mapping them to a specific competence(s). Competencies achievement may be ensured though conducting assessments. The paper explores the quality of assessment and verification (A&V) process that make CAMS DFW implementation more effective and reliable. It focuses on technical coaching as a main stage of the A&V process and how to enhance its quality and the outcome of the CAMS system accordingly

Modeling and control of a dynamic information flow tracking system

This thesis introduces and details the effort of modeling and control design of an information tracking system for computer security purposes. It is called Dynamic Information Flow Tracking (DIFT) system. The DIFT system is developed at the Computer Science Department at the University of New Mexico, works by tagging data and tracking it to measure the information flow throughout the system. DIFT can be used for several security applications such as securing sensor networks and honeypot - which is a trap set to detect, deflect, or counteract attempts at unauthorized use of information systems. Existing DIFT systems cannot track address and control dependencies, therefore, their applicability is currently very limited because important information flow dependencies are not tracked for stability reasons. A new approach is taken, aimed at stabilizing DIFT systems and enabling it to detect control dependencies at the assembly-level, through control theory. Modern control has been used to model several cyber-physical, computing, networking, economical... systems. In an effort to model a computing system using control theory, this thesis introduces a general hybrid systems framework to model the flow of information in DIFT when control dependencies are encountered. Information flow in DIFT is represented by a numeric vector called taint vector . The model suggested benefits from the characteristics of hybrid systems and its ability to represent continuous variables and discrete events occurring. The system is stabilized by making sure that the taint vectors represent the true information flow in control dependencies. This problem is solved by designing a PID and model predictive controller which guarantee that system does not over taint, while allowing information to flow properly. The modeling framework is validated by comparing simulations of the hybrid models against. This research provides a new approach to solve the DIFT over-tainting problems through modeling it as a hybrid system and forcing the constraints to be obeyed by the taint values.\u2

Extended Jacobian Elliptic Function Expansion Method and Its Applications in Mathematical Physics

In this work, an extended Jacobian elliptic function expansion method is proposed for constructing the exact solutions of nonlinear evolution equations. The validity and reliability of the method are tested by its applications to some nonlinear evolution equations which play an important role in mathematical physics
