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...

Despite the popularity of BPEL engines to orchestrate complex and executable processes, there are still only few approaches available which help to find the most appropriate engine for individual requirements. One of the more crucial comparison factors for middleware products in industry are the performance characteristics. There exist multiple studies in both industry and academia testing the ...

This study aims to explore the subject of performance evaluation in project management through the selection of relevant articles on the theme and their subsequent bibliometric analysis, in order to build knowledge among researchers on the subject. The research is characterized as exploratory, descriptive, theoretical-illustrative and adopts ProKnow-C (Knowledge Development Process-Constructivi...

This project consisted of performance testing and evaluation of concrete containing high-carbon fly ash and carbon fibers. One of the primary aims of this project was to further determine the effect of using high-carbon fly ash and carbon fibers on the electrical properties of concrete. This is a part of the continuing work performed initially by the UWM Center for By-Products Utilization (UWM-...

In performance testing of ATM switches and network of switches a variety of connection configurations is needed. In most of the cases, these configurations require one traffic generator and/or analyzer for each switch port. Since this equipment is rather expensive, it is desirable to define scalable configurations that can be used with a limited number of generators. In this paper we present a ...

In performing a fuzzy multiple linear regression model, important topics are: to measure the fitting quality of the model and to find the “best” set of input variables that explain the variation in the observed system responses. In this paper, by considering an exploratory approach, to express the quality of fit of a fuzzy linear regression model, a coefficient of multiple determination R2 for ...

This paper proposes the use of a mobile-cloud by combining mobile devices and the cloud together in a biodefense and emerging infectious diseases (BEI) research application scenario. A mobile-cloud framework is developed to facilitate the use of mobile devices to collect data for, and manipulate and interact with the scientific workflows running in the Cloud. In this framework, an independent t...

With the development of auto detection technology, applications of computer control system in automobile comprehensive performance test has developed into a new stage. Also the paper elaborates automobile comprehensive performance testing automatic control system's designing mentality, system composition, test process, and the characteristics of the system and function.

Performance bugs have classically been difficult to identify in high performance programs. The problem arises because there is a broad spectrum of causes of performance degradation, and because it may be necessary to apply specialized diagnostics to search the performance space. The prototype tuning environment we are developing enables one to explore the performance space of a program using cu...

An important part of electronic dance music (EDM) is the so-called beat. It is defined by the drum track of the piece and is a style defining element. While producing EDM, creating the drum track tends to be delicate, yet labor intensive work. In this work we present a touch-interface-based prototype with the goal to simplify this task. The prototype aims at supporting musicians to create rhyth...
