In this paper, a novel protocol for providing both client and server anonymity in peer-to-peer (P2P) based grids is presented. The protocol assumes individual nodes or users to be utility maximizing agents, and relies on an auction mechanism for trading of resources among them. The resources here can refer to data files, storage capacity, or computation power (i.e., CPU cycles) etc. The protoco...

An assessment of unstructured grids for use in Detached-Eddy Simulation (and more generally in Large-Eddy Simulation) of massively separated ows is presented. The role of the grid, its generation and re nement, are considered via calculation of three high-Reynolds number turbulent ows of aerodynamic interest: the massively separated ow over a forebody in cross ow, the ow over a delta wing at 27...

The intermittency of renewable energy sources makes the use storage systems (ESSs) indispensable in modern power grids for supply-demand balancing and reliability enhancement. Besides pumped-storage hydroelectric stations, deployment worldwide is still quite low. However, status quo might rapidly change as technologies are growing facilitating market regulations being ratified. Battery (BESSs),...

Distribution grids across the world are undergoing profound changes due to advances in energy technologies. Electrification of transportation sector and integration Distributed Energy Resources (DERs), such as photo-voltaic panels storage devices , have gained substantial momentum, especially at grid edge. Transformation technological aspects could directly conflict with existing distribution u...

Two new quasi-linear elliptic systems of partial differential equations to automatically generate twodimensional boundary conforming structured grids are formulated. One of the new systems generates grids with near-uniform cell areas. The other produces meshes with near-uniform coordinate line spacings. In both cases, the resulting grids conform to complex boundaries with severe singularities w...

nowadays multicriteria decision making (mcdm) methods are a useful tool for investigating natural resources and toaddress problems related to hydro systems. the goal of this research was to assess the daliri standardization method(dsm) to prioritize and make selections for application to mcdm. and to compare the dsm method with the utilityadditive (uta) method. the (dsm) method, unlike the (uta...
