The VuSystem is a software-intensive video environment developed on operating systems without real-time features. In the course of our work with this system, interesting questions have been brought up about how resources on a workstation can be best divided between applications, and what resource management features (if any) are required. This paper’s main purpose is to outline a rationale for ...

In network monitoring, an important issue is the number of tuples the data stream management system (DSMS) can handle for different network loads. In order to gracefully handle overload situations, some DSMSs are equipped with a tuple dropping functionality, also known as load shedding. These DSMSs register and relate the number of received and dropped tuples, i.e., the relative throughput, and...

In this thesis, we are working on the optimized execution of very large number of continuous queries de ned on data streams. Our scope includes both classical query optimization issues adapted to the stream data environment as well as analysis and resolution of overload situations by intelligently discarding data based on applicationdependent quality of service (QoS) information. This paper ser...

This paper discusses the usability needs of mobile applications for basic business management for Micro and Small Scale Enterprises (MSEs) in developing countries. This is based on results from a user study carried out in Uganda on 30 MSEs. The study was carried out on MyShop, an easy to use mobile business management application for cash transactions and book keeping designed for micro-entrepr...

this paper proposes an optimal power flow (opf) algorithm by direct load control (dlc) programs to optimize the operational cost of smart grids considering various scenarios based on different constraints. the cost function includes active power production cost of available power sources and a novel flexible load curtailment cost associated with dlc programs. the load curtailment cost is based ...

A Key component to future smart grids may be a microgrid system capable of integrating generation, load, and storage assets into an autonomous power system entity. A microgrid is intrinsically distributive in nature. In order to improve performance of a microgrid, a distributed and cooperative control is required. Agent technology is one of techniques for achieving the objectives of distributed...

This paper represents the mustard oil is a kind of renewable energy and alternative fuel of the future. In order to cope with the current situation of load shedding, and reduce dependence on imported fuels, the Bangladesh government to encourage the use of renewable energy. Because the diesel engine with multiple functions, including small pumping irrigation system and backup generators, diesel...

Building robust network monitoring applications is hard given the unpredictable nature of network traffic. Complex analysis on streaming network data usually leads to overload situations when presented with anomalous traffic, extreme traffic mixes or highly variable rates. We present an on-line predictive load shedding scheme for monitoring systems that quickly reacts to overload situations by ...

The frequency of power system is very sensitive to load changing when operating in islanded mode. This may causes overloading or loss of generation cases. Under-Frequency Load Shedding (UFLS) Scheme is commonly applied to stabilize the frequency during these cases. Conventional UFLS scheme operates successfully in interconnected grid system and may not work well when applied to DG based system ...

In the past, Battery Energy Storage System (BESS) is used for primary frequency regulation. As developments in batteries progress, advancement in applications of BESS including the implementation in high power penetration is expected. Load shedding is one of frequency control methods during stand-alone operation, and the performance of frequency control improves in combination with BESS. Howeve...
