entrepreneurship is the process of value setting by providinga unique set of sources for making effective use of opportunities;thus, caring about it seems to be a must. the present paper aims toinvestigate the effect of information technology management on managers’entrepreneurship in tabriz car-parts manufacturing industry. tothis end, four hypotheses were tested in the study. the population o...

the establishment of good process safety management (psm) is widely considered as the most effective means of improving safety levels in process industries. this study was conducted to evaluate the feasibility of establishing and implementing psm requirements based on occupational health and safety assessment series 18001 standards (ohsas 18001) and health, safety and environment management sys...

This paper presents Pirrus, a replica management system that addresses the problem of providing data availability on a wireless sensor network. Pirrus uses probabilistic failure models (e.g., derived from environmental conditions and estimation of available energy) to adaptively create and maintain a number of replicas of the data. The replica management is formulated as an energy optimization ...

Wireless communication is increasingly used to manage large-scale crises (e.g., natural disasters or a large-scale city fire). Communication has traditionally been based on cellular networks. However, real-life experience has proven that the base stations of these networks may collapse or become unreachable during a crisis. An incident commander must also know as much information as possible ab...

telemedicine has changed the way of health care. it is an indispensable tool in the hands of doctors to accelerate and facilitate the process of data interchange. wireless networks consist of small nodes with communications capabilities. development of wireless networks of telemedicine system is highly demanded since these networks promise a wide range of potential applications. in this paper t...

In this paper, we investigate different battery management policies for a wireless node. The goal is to increase the lifetime of a node by exploiting its battery characteristics. We have presented a framework for maximizing the lifetime of a battery by using an optimal management. In this work, we propose and compare the performance of several suboptimal battery management strategies which are ...

The aim of the FAST project is to provide an implementation of a lazy functional language on a transputer array. An important component of this system is a highly optimising compiler and runtime system for a single transputer. Efficient storage management is crucial in such an implementation, and this paper explores the demands placed on the storage manager by our compiled code. Statistics are ...

lean thinking requires certain techniques and tools to support lean processing and to penetrate an organization in which 5s system (sorting, set in order, shining, standardization, sustaining) is to develop value process workflow system. kanban, a card containing a set of manufacturing specifications and requirements used to regulate the supply of components, is one of the most famous and impor...

Three-parameter lognormal distribution has been demonstrated for applications in electromigration data analysis, especially for Cu interconnect structures with insufficient redundancy. Examples are given on estimating parameter values from experimental data using the maximum likelihood method. Detailed analyses are presented on confidence bound estimations of the parameters and their propagatio...

A citations analysis Purpose of this paper This paper addresses the question: should the world s top universities be led by top researchers, and are they? Design / methodology / approach The lifetime citations are counted by hand of the leaders of the world s top 100 universities identified in a global university ranking. These numbers are then normalised by adjusting for the different citation...
