In order to prevent violation of service-level objectives and to guarantee good user experience, detection of symptoms such as slow application response, degraded transaction throughput, and service outages, is crucial. We propose a black-box approach for detecting such symptoms in service performance behaviour without intrusive application instrumentation. In case a known baseline behaviour ex...

Introduction: If the patients are not satisfied with the hospital, this results in switching behavior of patients. In this situation, among different hospitals, the patients choose the hospital with higher level of service quality. So, the main aim of this paper is investigating the effect of hospital's service quality on switching behavior of inpatients in Shahid Sadoughi Hospital of Yazd. Me...

In-service education programs have provided the professional development level of companies' employers, in the high quality form. The applying of in-service education programs has been a key component of professional development process for staff agro-industry Company. The study is utilized experimental Solomon four group designs to determine the impact of in-service education programs on agro-...

Workload characterization is an important and basic step for performance modeling and capacity planning. Traditional approaches for workload characterization often require sophisticated and time-consuming user assistance. In this paper we describe a number of algorithms for automatically classifying workloads and for determining what resources a workload used even when the operating system does...

in the current engineering practices, buildings are commonly designed for an effective lifetime of 50 years. this lifetime can increase the cost of buildings with short lifetimes and can reduce the safety level of buildings with large lifetimes. in this paper, a “service-life factor” has been defined. applying this factor into the nominal values of live, earthquake, wind, and snow loads, the ef...

Research into active networking has provided the incentive to re-visit what has traditionally been classified as distinct properties and characteristics of information transfer such as protocol versus service; at a more fundamental level this paper considers the blending of computation and communication by means of complexity. The specific service examined in this paper is network self-predicti...

An intention to adopt IP protocol for future mobile communication and subsequent extension of Internet services to the air interface calls for advanced performance modeling approaches. To provide a tool for accurate performance evaluation of IP-based applications running over the wireless channels we propose a novel cross-layer wireless channel modeling approach. We extend the small-scale propa...

abstract background: there are several evaluation models that can be used to evaluate the effect of in‑service training; one of them is the kirkpatrick model. the aim of the present study is to assess the in-service training of cardiopulmonary resuscitation (cpr) for nurses based on the kirkpatrick’s model. materials and methods: this study is a cross‑sectional study based on the kirkpatrick’s ...
