Managing the performance of large, distributed systems requires exible and scalable approaches to automating measurement navigation. Unfortunately, existing approaches achieve scalability by severely limiting exibility. Considered here is an approach that infers navigations from a dimensional representation of the measurement name space. Doing so provides exible navigation and results in dramat...

A new approach to monitoring the runtime behaviour of parallel programs will be presented. Our approach provides a speci cation language to build measurement models which describe formally what to be measured. Driven by a measurement model, performance measurement can be carried out automatically.

Context: Software performance models can be obtained by applying for specific roles, skills and techniques in software life cycle, and it depends on formulating the software problem as well as gathering the performance requirements. This paper presents a preliminary review of the software performance models. This constitutes a reference for the IT companies and personnel that help them select t...

the purpose of this study is to provide a model for performance evaluation of sepah bank branches by using partial indicators through combining controllable and uncontrollable potential variables with performance variables. with description and expansion of performance concepts of branches, a complete list of pre-test variables, including forty nine potential variables and five performance vari...

Performance is a crucial factor in software system. For many software development groups, it remains easier to wait until a system has been built before evaluating its performance. Among the three most used techniques, measurement, simulation and analytic modeling , measurement is believed to be the most accurate method. But it is only feasible after system is implemented. Most organizations re...

CONTEXT Item response theory (IRT) measurement models are discussed in the context of their potential usefulness in various medical education settings such as assessment of achievement and evaluation of clinical performance. PURPOSE The purpose of this article is to compare and contrast IRT measurement with the more familiar classical measurement theory (CMT) and to explore the benefits of IR...

A working paper in the INSEAD Working Paper Series is intended as a means whereby a faculty researcher's thoughts and fmdings may be communicated to interested readers. The paper should be considered preliminary in nature and may require revision. and our Editor and anonymous reviewers for their very helpful comments on this research. Measurement Quality Issues in Dyadic Models of Relationships...

Measurement error is omnipresent in psychological data. However, the vast majority of applications of autoregressive time series analyses in psychology do not take measurement error into account. Disregarding measurement error when it is present in the data results in a bias of the autoregressive parameters. We discuss two models that take measurement error into account: An autoregressive model...

Lambing interval is a relevant reproductive indicator for sheep populations under continuous mating systems, although there is a shortage of selection programs accounting for this trait in the sheep industry. Both the historical assumption of small genetic background and its unorthodox distribution pattern have limited its implementation as a breeding objective. In this manuscript, statistical ...
