This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...

Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a sing...

A metafrontier slack-based efficiency measure is presented to measure environmental efficiency for various regions in China. The objective of the new approach is to investigate the change of environmental efficiency while incorporating group heterogeneities and all variable slack and environmental pollutants into environmental efficiency analysis. Global production technology is used to improve...

This work presents a novel slack management technique, the ’Service Rate Proportionate(SRP) Slack Distribution’, for real-time distributed embedded systems to reduce energy consumption. The proposed SRP based Slack Distribution Technique has been considered with EDF and Rate Based scheduling schemes that are most commonly used with embedded systems. A fault tolerance mechanism has also been inc...

In digital forensics, different forms of slack space can be used to hide information from either the operating system or other users, or both. While some forms are easily detectable others are very subtle, and require an experienced forensic investigator to discover the hidden information. The exact amount of information that can be hidden varies with the form of slack space used, as well as en...

A real time implementation for allocating slack to aperiodic processes in MetaH is nearing comple tion The slack scheduling algorithm used is based on the slack stealer originally proposed in with practi cal extensions to allow for support of process criticali ties multiple process streams of di erent criticalities competing for pooled slack and inclusion of run time overheads in the slack func...
