In order to compare the impact of passive (like network restructuring) or active (like on-load-tap-changer) grid management measures a novel tool was developed, which performs specific load flow benchmarks tests using synthetic daily load and infeed profiles. In this paper first preliminary results of the analysis of a real urban medium voltage distribution grid with 122 substations using this ...

• All tested blends offer a HC and CO advantage over conventional diesel at low-load. emissions increase with increasing biofuel content medium-load high-EGR LTC. Crevice volume non-negligible for LTC operating points. An experimental study was performed on single-cylinder high-speed direct-injection research engine to determine the effects of biodiesel combustion characteristics during low tem...

A layer of viscoelastic material embedded in an infinite medium also viscoelastic tends to fold through instability when the system is compressed in a direction parallel with the layer. This phenomenon which was treated previously by using an approximate plate theory, [l, 21, is analyzed here by using an exact theory for the deformation of a continuum under prestress [3, 4, 5, 61. The effect of...

The paper presents an analysis of three object replication strategies based on reliable multicast protocols. A multi-class queueing model is used for obtaining performance characteristics of each strategy. The strategies are compared for a wide set of parameters showing the best strategy suitable for a given situation: the parallel update strategy has good performance for medium and high load; ...

When a layer of material embedded in an infinite medium is subject to a comfiression parallel with the layer an instability tends to develofi which manifests itself in the folding of the layer. This phenomenon is examined here for the general case where the layer and the surrounding medium are both viscoelastic. This problem which was examined in preliminary form in an earlier publication [6]t ...

Electrical load forecasting is well-known as one of the most important challenges in the management of electrical supply and demand and has been studied extensively. Electrical load forecasting is conducted at different time scales from short-term, medium-term and long-term load forecasting. Adaptive neuro-fuzzy inference system is a model that combines fuzzy logic and adaptive neuro system and...

Opportunistic routing (OR) has been proposed to improve the performance of wireless networks by exploiting the multi-user diversity and broadcast nature of the wireless medium. It involves multiple candidate forwarders to relay packets every hop. The existing OR doesn’t take account of the traffic load and load balance, therefore some nodes may be overloaded while the others may not, leading to...

The prevalence of dynamic-content web services, exemplified by search and online social networking, has motivated an increasingly wide web-facing front end. Horizontal scaling in the Cloud is favored for its elasticity, and distributed design of load balancers is highly desirable. Existing algorithms with a centralized design, such as Join-the-Shortest-Queue (JSQ), incur high communication over...
