Introduction: In radionuclide imaging, object scatter is one of the major factors leading to image quality degradation. Therefore, the correction of scattered photons might have a great impact on improving the image quality. Regarding this, the present study aimed to determine the main and sub-energy windows for triple energy window (TEW) scatter correction method usin...

The purpose of this study is to indicate several areas of interest within the Yahoo! Messenger application that are of forensic significance. This study will mainly focus on new areas of interest within the file structure of Windows Vista and Windows 7. One of the main issues with this topic is that little research has been previously conducted on the new Windows platforms. The previously condu...

Broadcasting offers a bandwidth-efficient way of delivering popular content in media-on-demand (MoD) systems. Harmonic windows scheduling (HWS) is a mathematical framework that is relevant to bandwidth minimization in MoD broadcasting. Given c channels, the optimal HWS problem tries to schedule as many pages of a video as possible in the c channels. Let κ be the largest integer n satisfying Hn ...

As a systems administrator on call at any time of day, I want to explore ways to manage the environment and handle emergencies remotely. In this paper, I look at a number of options for remote administration using compact devices. While the most obvious form of remote administration is a laptop computer, not every organization has the budget to provide these to their systems administrators. Als...

This paper quantiies the performance of X applications on an Ethernet network. We replicated experiments performed by Basil and Williamson 2] in a single network segment to determine if the results would be similar in a diierent computing environment. Then we extended the work by running similar tests across more than one network segment. In general, results were similar, although network load ...

delivering perishable products to customers as soon as possible and with the minimum cost has been always a challenge for producers and has been emphasized over recent years due to the global market becoming more competitive. in this paper a multi-objective mix integer non-linear programming model is proposed to maximize both profits of a distributer and the total freshness of the several produ...

Windows NT is a 32-bit, preemptive multitasking operating system that includes comprehensive networking capabilities and several levels of security. Microsoft markets two version of Windows NT: one for workstations—appropriately named Windows NT Workstation—and a second for servers—Windows NT Server. This article, which describes the workings of the NT architecture, collectively references both...

The chronicles kept by an explorer as he or she journeys into new territories can be invaluable for those who come later. The writing describe successes and failures, warning and hints to other possible solutions yet unfound. The evolution of a network is not different than the Lewis and Clark expedition of the early 1800’s. Each day we learn something new. Either our proposed solution worked o...
