Dramatic enrichment of high speed communication technology at affordable costs enabled the resolution of problems related to the limitations of power supply. Therefore, introduction of Smart Grid for managing highly controllable power grids has become indispensable. Its very important part is Distribution Management System (DMS). These sophisticated systems execute a large number of workflows with very high resource requirements. In this paper dynamic, centralized scheduling strategies for allocating DMS workflows are presented and compared. Also, a distributed scheduling algorithm for DMS calculation engine is developed. It is argued that minor investment in the resources and introduction of a hybrid scheduling algorithm leads to the significant boost of the system performance. The hybrid scheduling algorithm is the result of combining centralized and distributed scheduling strategies. Experimental study shows that considerable improvement of overall system performance is achieved by using developed algorithms for designing effective schedulers when make-span and workload are optimized.
Grid computing could be the future computing paradigm for enterprise applications, one of its benefits being that it can be used for executing large scale applications. Utility Management Systems execute very large numbers of workflows with very high resource requirements. This paper proposes architecture for a new scheduling mechanism that dynamically executes a scheduling algorithm using feedback about the current status Grid nodes. Two Artificial Neural Networks were created in order to solve the scheduling problem. A case study is created for the Meter Data Management system with measurements from the Smart Metering system for the city of Novi Sad, Serbia. Performance tests show that significant improvement of overall execution time can be achieved by Hierarchical Artificial Neural Networks.
The purpose of insurance is to provide security for the clients and its partners, by perfectly and responsibly understand, manage, monitor and carry the risk. As a powerful motor of global industry, insurance also have a potential to contribute enhancement of society, economy and governance, with strong positive influence on the environment. Sustainable insurance is a strong commitment of the insurance sector to recognize the sustainable values and determination to integrate these values in their strategy. In the new way of looking to the future, principals of insurance sector are in the best position to initiate and to assist in resolving complex global challenges-climate change issues and impoverishment of natural resources. In this paper will be discussed about the auto Telematics Usage Based Insurance products. These products are promoted by the insurance sector in accordance with natural progress of society and legal framework, evolution of technology and changes in demands. They can be classified as perspective solutions for sustainable insurance, because they directly affect environmental, safety, energy and resources saving, and overall social improvement issues.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
