Purpose More than 6,500 megavoltage teletherapy units are needed worldwide, many in low-resource settings. Cobalt-60 units or linear accelerators (linacs) can fill this need. We have evaluated machine performance on the basis of patient throughput to provide insight into machine viability under various conditions in such a way that conclusions can be generalized to a vast array of clinical scen...

The practice of restricting personnel entry to swine farms for extended periods of time following contact with other pigs (downtime) is a highly controversial subject throughout the global swine industry. For many years, downtime periods ranging from 48 to 96 hours have been enforced to reduce the risk of pathogen introduction to farms by personnel, despite a lack of data supporting these perio...

This paper provides a review of the components of disaster tolerant computing and communications and reviews the current state in light of recent man-made terrorist events. The paper examines the relationships between disaster tolerant systems, Information Technology (IT) application availability and executive level management visibility necessary for successful system operations in the event o...

In this paper, we improve some previous definitions of fuzzy-type Turing machines to obtain degrees of accepting and rejecting in a computational manner. We apply a BFS-based search method and some level’s upper bounds to propose a computational process in calculating degrees of accepting and rejecting. Next, we introduce the class of Extended Fuzzy Turing Machines equipped with indeterminacy s...

This paper deals with the transient analysis of K-out-of-N: G system consisting of Noperatingmachines. To improve system reliability, Y cold standby and S warm standbys spares areprovided to replace the failed machines. The machines are assumed to fail in multiple modes. At leastK-out-of-N machines for smooth functioning of the system. Reliability and mean time to failure areestablished in term...

Ensuring the minimum tension during thread processing on technological equipment allows to reduce downtime due elimination or significant reduction of breaks. Minimization is ensured by optimization shape filling line, in which total angle coverage guides will be minimal. This problem solved using Dijkstra’s algorithm finding optimal path a directed graph. The computer program for implementing ...

Induction motors are the most common means of converting electrical power to mechanical power in the industry. Induction machines were typically considered robust machines; however, this perception began to change toward the end of the last decade as low-cost motors became available on the market. Nowadays the most widely used induction motor in the industry is a machine which works at the limi...

Executive Summary The overall concept of Total Cost of Ownership for server clusters has been an important issue within the IT community for many years. Numerous studies and customer experiences have proven that purchase price alone is not an adequate measurement to compare server clusters from various vendors. Other factors, including the costs to manage and maintain the servers, as well as th...
