low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. it was thought that the hplc is the best method of the determination of organic acids in the apple juice. in this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for extr...

The ‘buffer zone’ frames the contested space that university researchers must persistently animate and mediate to successfully pursue participatory research with public third sector partners. This article explores this conceptualisation through a consideration of political ethical dilemmas in practice. We contend identify, respond reflect on everyday momentous by combining technical, relational...

In this paper we study two echelon multi-server tandom queueing systems where customers arrive according to a poisson process with two different rates. The service rates at both echelons are independent of each other. The service times of customers is assumed to be completed in two stages. The service times at each stage are exponentially distributed. At the first stage, the customers may balk ...

We find “combinatorially optimal” (guaranteed by the degree-sequence alone) independent sets for graphs and hypergraps in linear space in the semi-streaming model. We also propose a new output-efficient streaming model, that is more restrictive than semi-streaming (n·log n space) but more flexible than classic streaming (log n space). The algorithms in this model work in poly-logarithmic space,...

Real-time traffic in Cellular IP network is considered to be important and therefore given priority over nonreal-time. Buffer is an important but scarce resource and to optimize Quality of Service by managing buffers of the network is an important and complex problem. Evolutionary Algorithms are quite useful in solving such complex optimization problems, and in this regard, a two-tier model for...

In this paper, we consider the problem of boundary fill of a 4 or 8-connected region in a graphic device having a color image frame-buffer memory. We provide an algorithm that solves the problem in a time linear in the number of pixels in the region and requiring only constant memory space in addition to the frame-buffer memory itself. We map this problem to a boundary fill problem in a general...

Optimization via simulation consists in applying iteratively two detached models until an optimality condition is reached: a simulation model for predicting the system performance and an optimization model for finding out the optimal solution. Mathematical programming representation has been recently used to describe the behavior of discrete event systems as well as their formal properties. Thi...

Switch design for interconnection networks plays an important role in the overall performance of multiprocessors and computer networks. In this paper, a new switch design, namely FC-CB, is proposed that offers low average message latency and high throughput over a wide range of input workloads. The FC-CB switch incorporates wormhole routing and virtual channels with a full crossbar connection. ...

We introduce the N-buffer as a tool for multiresolution depth map representation. This neighborhood buffer encodes the value and position of local depth extrema at different scales in an image cube, in contrast to the image pyramid. The resulting increase in storage space is largely compensated by the following benefits: objects of any size can be culled in constant time against an occlusion ma...
