Linear and integer programs are considered whose coefficient matrices can be partitioned into K consecutive ones matrices. Mimicking the special case of K = 1 which is well-known to be equivalent to a network flow problem we show that these programs can be transformed to a generalized network flow problem which we call semi-simultaneous (se-sim) network flow problem. Feasibility conditions for ...

Accurate and efficient simulation of large parallel applications can be facilitated with the use of direct execution and parallel discrete-event simulation. This paper describes MPI-SIM, a direct execution-driven parallel simulator designed to predict the performance of existing MPI and MPI-IO application. MPI-SIM can be used to predict the performance of these programs as a function of archite...

This paper presents the stability evaluation of a Simulation–Stimulation (Sim–Stim) interface that integrates hardware to software to perform Hardware-In-the-Loop (HIL) studies for testing and developing electrical equipment. Modeling issues of such an interface are discussed and a practical Sim–Stim interface model whose parameters are sampling rate and time delay is developed for the theoreti...

This study is concerned with the uncertainty principles which are related to the Weyl-Heisenberg, the SIM(2) and the Affine groups. A general theorem which associates an uncertainty principle to a pair of self-adjoint operators was previously used in finding the minimizers of the uncertainty principles related to various groups, e.g., the one and twodimensional Weyl-Heisenberg groups, the one-d...

Electronic Government initiatives, such as seamless public services delivered at one-stop government portals, require establishing collaborative networks among publicand private-sector organizations. However, semantic interoperability problems emerge as these organizations may differ in the terms and meanings they use to communicate, express their needs and describe resources they make availabl...

In this paper we present an architecture based on a Java (J2SE, J2EE, J2ME and Java Card) platform supporting a secure channel from a Mobile Operator to the SIM card. This channel offers the possibility of end to end security for delivery of large data files to a GSM SIM card. Such a secure channel could be used for delivery of high value content that requires a high bandwidth channel – perhaps...

    The solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. Fused dispersions (FDs) of simvastatin (SIM) using PEO-PPO block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. The accumulative s...

Smart cards are fundamental technology in modern life. It is embedded in numerous devices such as GPS devices, ATM cards, Mobile SIM cards and many others. Mobile devices became the evolution of technology. It becomes smaller, faster and supports large storage capabilities. Digital forensics of mobile devices that maybe found in crime scene is becoming inevitable. The purpose of this research i...

Conventional approaches to text analysis and information retrieval which measured document similarity by using considering all of the information in texts are a relatively inefficiency for processing large text collections in heterogeneous subject areas. This paper outlined a new text manipulation system FA-Sim that is useful for retrieving information in large heterogeneous texts and for recog...
