The grid square method as used in Japan has been standardized by the government, by use of the lines of the earth's latitude and longitude. The basic unit covers an area of approximately one square kilometer. An evaluation of this method is focused on the geographical distribution of cancer mortality in the city of Tokyo over a period of six years. The results indicated that for stomach and lun...
The quantity of installed photovoltaic (PV) systems in the German distribution grid is still increasing. In some areas the installed PV capacity exceeds 5.0 kWp [1] per house connection (HC). Therefore the load flow changes its characteristics and leads to new requirements for grid dimensioning. Additionally, the feed-in is carried out via inverter systems and a lot of power electronics have to...
The scatter view shows the distribution of items on the high-resolution grid in relation to the trajectory clusters using a dot representation. The density view visualizes the sample distribution density in a color coded heatmap representation. Alternative heatmaps show the quantization error, the U-Matrix, etc. The star view is a connector-based view which indicates for each data sample its ne...
1/4 My research interests are in the areas of power system optimization and control, grid integration of distributed energy resources including renewables and energy storage systems (ESS), distribution system optimal voltage regulation, and power markets and power system economics. I conduct fundamental and applied research on efficient grid integration of distributed energy resources from both...
We present a general framework for constructing and analyzing finite volume methods applied to the mixed formulation of second-order elliptic problems on quadrilateral grids. The control volumes, or covolumes, in the grids overlap. An overlapping finite volume method of this type was first introduced by Russell in [T. F. Russell, Tech. report 3, Reservoir Simulation Research Corp., Tulsa, OK, 1...
The breeder genetic algorithm BGA depends on a set of control parameters and genetic operators. In this paper it is shown that strategy adaptation by competing subpopulations makes the BGA more robust and more eecient. Each subpopulation uses a diierent strategy which competes with other subpopulations. Numerical results are presented for a number of test functions.
We consider the general problem of distributed and fair peer-to-peer (p2p) allocation of a common, refillable resource. This problem recurrs in a number of scenarios, for example grid computing, content distribution, Internet Service Provider service sharing, and file sharing over asymmetric channels. We present several distributed schemes for this allocation problem, and show that these scheme...
The mean value analysis algorithm is used to model a database application that runs over a grid of computers. A bound on the maximum throughput is modeled by assuming a uniform distribution of requests across the grid. Then, a non-uniform distribution of requests was modeled. Also, the number of clients was varied. Then, the model was modified to reflect a proposed change in the application. Fi...
game where agents learn prediction models regarding potential coalition partners and thus, can respond in an agile manner to situations that are occurring in the grid, by means of negotiating and formulating a priori solutions , with respect to the estimated behaviour of the system. To sum up, we are providing a novel framework for managing the grid efficiently by envisioning a game layer on to...
there area lot of mobile computer devices with a variety of applications and users tend to use them more. due to the limitations of mobile devices, running most of the procedures are impossible. to resolve this problem, mobile devices can be connected to the grid, to use the facilities of grid. on the other hand the communication mechanisms are different for each device and they cannot be conne...
