Wireless and mobile networks have experienced a great success in the past few years. However, any single type of wireless and mobile network cannot meet all types of service requirements. For example, no single type of existing wireless and mobile network can provide both wide coverage and high bandwidth services. In order to provide more comprehensive services, an integrated heterogeneous wire...

Exploiting cognition to the cache-enabled deviceto-device (D2D) communication underlaying the multi-channel cellular network is the main focus of this paper. D2D pairs perform direct communications via sensing the available cellular channels, bypassing the base station (BS). Dynamic service is considered and the network performance is evaluated with the stochastic geometry. Node locations are f...

This paper describes a complete system for reading typewritten lexicon words in noisy images in this case museum index cards. The system is conceptually simple, and straightforward to implement. It involves three stages of processing. The first stage extracts row-regions from the image, where each row is a hypothesized line of text. The next stage scans an OCR classifier over each row image, cr...

spurred by intensifying competition in global markets, most companies have been increasingly implementing supply chain management (scm) and information systems (is) practices. as well, globalization policies have created a more intensive competition amongst manufacturers; in additional the priority of supply over demand, market competition and importance of some factor such as quality, accounta...

Excellence Synergic Index (ESI) is a new method for the excellence measurement. This technique is a causal method. ESI method was developed for studying the relations and interaction of excellence criteria and organizational pathology. By “ESI”, it is possible to measure the performance excellence of any service enterprises, to diagnosis organizational pathos and to propose problem-solvin...

In this paper, we present a transient analysis of the system contents in a two-class priority queue with single-slot service times. In particular, we derive an expression for the generating function of the transient system contents of both classes. Performance measures are calculated from this generating function. Finally, by means of a numerical example we investigate the impact of the traffic...

regarding to rapidly changing and highly competitive business environment it will become increasingly important for organizations to measure their performances appropriately. with respect to special characteristics of pharmaceutical industry and lack of reported performance measurement, this study tries to design an integrated performance measurement model for pharmaceutical companies. for gene...

background and objectives: there is a growing tendency in iran’s health sector for adoption of standard excellence models for improving quality in healthcare organizations. the european foundation of quality management (efqm) model is a widely used framework for continuous quality management within healthcare facilities. the purpose of this article is to extend the view of current status of qua...

Real-Time Mach provides real-time thread and real-time synchronization facilities. A real-time thread can be created for a periodic or aperiodic activity with a timing constraint. Threads can be synchronized among them using a real-time version of the monitor based synchronization mechanism with a suitable locking protocol. In Real-Time Mach, we have implemented several locking policies, such a...

Abstract This study aims to examine the importance and performance analysis using a diagonal regression approach. Scale measurement used semantic differential. The of coefficient was map coordinates balance assessments with an estimation data spread standard error at rate 5%. results indicate that there are 5 strategic areas IPA: high priority be improved, (ISO-IPA), low priority, keep up good ...
