Botnets have traditionally been seen as a threat to personal computers; however, the recent shift to mobile platforms resulted in a wave of new botnets. Due to its popularity, Android mobile Operating System became the most targeted platform. In spite of rising numbers, there is a significant gap in understanding the nature of mobile botnets and their communication characteristics. In this pape...

Many studies have worked on virtual laboratory for desktop computers, yet the development of virtual laboratories for mobile devices is still at a developing stage because of its interface peculiarities and the assessment for its evaluation is yet to be established. This research has explored the use of Mobile Virtual Laboratory (MVL) for laboratory practicals in institutions of higher learning...

On traditional operating systems only trusted software such as privileged servers or the kernel can manage resources. This thesis proposes a new approach, the exokernel architecture, which makes resource management unprivileged but safe by separating management from protection: an exokernel protects resources, while untrusted application-level software manages them. As a result, in an exokernel...

As the price of CPU chips continues to fall rapidly, it will soon be economically feasible to build computer systems containing a large number of processors. The question of how this computing power should be organized, and what kind of operating system is appropriate then arises. Our research during the past decade has focused on these issues and led to the design of a distributed operating sy...

In operating systems, we usually refer to a running instance of a data structure (data type) as an object. Locating dynamic runtime kernel objects in physical memory is the most difficult step towards enabling implementation of robust operating system security solutions. In this paper, we address the problem of systemically uncovering all operating system dynamic kernel runtime objects, without...

This operating year marks an upgrade to the computer system charged with control and data acquisition for neutral beam injection system’s heating at the DIII-D National Fusion Facility, funded by the US. Department of Energy and operated by General Atomics (GA), This upgrade represents the third and latest major revision to a system which has been in service over twenty years. The first control...

Computer aided design and computer aided modeling tools are becoming increasingly important in the design and performance evaluation of communication systems. In this work, we report on the computer simulation modeling study of terrestrial digital microwave radio transmission, using Block Oriented System Simulator package (BOSS). The work concentrates on semi-analytical error rate evaluation in...

The realtime manipulation of audio with desktop computers has become both possible and popular over the last several years. Perhaps the most important aspect that determines the suitability of a computer operating system for this application is the latency of its audio system. This paper describes the results of an experiment measuring the audio latency of several current desktop operating syst...
