The ability to measure the energy consumed by cloud infrastructure is a crucial step towards the development of energy efficiency policies in the cloud infrastructure. There are hardware-based and software-based methods of measuring energy usage in cloud infrastructure. However, most hardware-based energy measurement methods measure the energy consumed system-wide - including the energy lost in...

  Background: The employees of welfare centers, due to the special conditions of their work, may be exposed to excessive occupational stress and workload . Thus, the aim of this study was to determine the effect of workload and occupational stress on the general health of female employees of public welfare centers.   Materials and Methods: This was a correlational research on 63 fe...

The primary objective of this research project was to investigate models for monitoring and predicting subjective workload in the control of complex systems. Such models would enable systems to use workload levels to distribute tasks optimally in addition to identifying levels of workload which could lead to a serious breakdown in performance. In the aircraft-pilot system, for example, such cap...

This paper presents a comparison of two versions of an Emergency Automated Response System (EARS), a fully manual version and a partially automated version. User evaluations involving both versions of the system were conducted using a low workload task and a high workload task. The results indicate that the automation employed by the partially automated system decreased overall response time an...

The possibilities for measuring workload or driver distraction by means of the Peripheral Detection Task during driving with in-vehicle equipment were investigated in a driving simulator experiment. The results show that the Peripheral Detection Task is a very sensitive method of measuring peaks in workload, induced by either a critical scenario or messages provided by a driver support system. ...

Background: The high workload of nurses in hospitals has been identified as a patient safety and worker stress problem. Psychological empowerment is a motivational concept demonstrated in four dimensions: meaning, competence, self-determination, and impact. Objective: This study investigated the relationship between nurses’ workloads and psychological emp...

Objectives: One of the applications of ergonomics disciplinary is designing driver workstation compatible to users’ characteristics. The aim of this study was evaluation of interior design of Shoka vehicle with respect to the accommodation for Iranian population and proposing suggestions for customizing design of the vehicle. Methods: This study was a descriptive-analytical study conducted a...

Evaluation methods for parallel computers often require the availability of relevant workload information. To this end, workload traces recorded on real installations are frequently used. Alternatively, workload models are applied. However, often not all necessary information are available for a specific workload. In this paper, a model is presented to recover an estimated job execution time wh...

OBJECTIVE To determine if the comparison of acute and chronic workload is associated with increased injury risk in elite cricket fast bowlers. METHODS Data were collected from 28 fast bowlers who completed a total of 43 individual seasons over a 6-year period. Workloads were estimated by summarising the total number of balls bowled per week (external workload), and by multiplying the session ...
