Energy is the basic necessity for the economic development of a country. Many functions necessary to present-day living grind to halt when the supply of energy stops. It is practically impossible to estimate the actual magnitude of the role that energy has played in building up present-day civilization. In this modern world, the dependence on electricity is so much that it has become a PART & P...

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 ...

This paper proposes a new adaptive underfrequency load shedding scheme (UFLS) to avoid frequency instability in electrical power system during abnormal wide area disturbances. The developed is based on online monitoring of the distance relay zone 3 decisions some tie lines using (WAMS) and SCADA/EMS systems, check rapidly reliably uncontrolled islanding conditions and, permit an automatic actio...
