introduction: medical records department (mrd) is important for evaluating, planning and prioritizing health care services. the major aim of this study was to evaluate the performance of the mrds of hospitals using multi-criteria decision-making approach in the selected hospitals of isfahan city, iran. methods: this was an analytical and cross-sectional study that was conducted in spring 2008 i...

clinical training is an important process in residency academic program in different fields. in this cross-sectional descriptive study, we identified the views of clinical residents about clinical training status at yazd university of medical sciences at their second-year of residency or above. we used questionnaire as the instrument for collecting information and select all residents as the sa...

We propose performance profiles — distribution functions for a performance metric — as a tool for benchmarking and comparing optimization software. We show that performance profiles combine the best features of other tools for performance evaluation.

Wireless camera networks provide a unique opportunity for collaborative surveillance. Performance evaluation and optimization of camera networks, however, has seldom been addressed. This chapter fills this gap by detailing an approach by which individual cameras and a whole network of cameras can be simultaneously optimized in terms of Pareto efficiency using multi-objective optimization of per...

We present the BTLA (Base Tree Link Augmentation) multicast routing infrastructure for heterogeneous wireless/wireline networks. BTLA has two goals: (a) to reduce the latency and overhead of joins, leaves, and handoffs in regions that experience high group dynamics and mobility, and (b) to optimize the multicast tree for stable regions that do not experience frequent group dynamics. BTLA consis...

The paper analyses the topic of service system productivity and profitability. Main focus of the research is self-service area, namely, the increase of ATM network productivity. Paper presents performance evaluation of self-service systems and improvement model for its increasing profitability. This model combines internal and external quality criteria and provides detailed understanding of the...

This paper presents a statistical approach for detecting corners from chain encoded digital arcs. An arc point is declared as a corner if the estimated parameters of the two fitted lines of the two arc segments immediately to the right and left of the arc point are statistically significantly different. The corner detection algorithm consists of two steps: corner detection and optimization. Whi...

In this paper, we study a novel type of spatial queries, namely Nearest Window Cluster (NWC) queries. For a given query location q, NWC (q, l,w,n) retrieves n objects within a window of length l and width w, where the distance between the query location q to these n objects is the shortest. To facilitate efficient NWC query processing, we identify several properties and accordingly develop an N...

Path traversals have been recognized as one of the strengths of object-oriented query processing as object retrieval can be carried out through pointer navigation. Apart from path traversals, explicit join between objects is sometimes necessary in Object-Oriented Databases (OODB), due to the absence of pointer connections or the need for value matching between objects. Like in Relational Databa...
