In this paper the skew affecting a multimedia traffic stream when N multimedia streams are mixed in an ATM multiplexer is evaluated. To this purpose a multimedia source is modeled by an arrival process defined as the superposition of heterogeneous correlated arrival processes, each of which models one monomedia source by means of an MMBP process whose transition probabilities are functions of t...

In order to model traffic stream speed resulting from complex interactions among different vehicle types in a heterogeneous/mixed traffic volume, an Artificial Neural Networks (ANN) approach is exploited. Two different categories of ANN model are attempted based on input vectors used. The performance of both categories of ANN model is evaluated using traditional evaluation framework. In additio...

Skeletal deformities seriously relegate the biological performance of fish. The frequency of occurrence of different types of meristic variations and skeletal deformities were shown in population of Mahseer fish, Tor putitora, in two main reservoirs; Korang stream, Islamabad and Dhobi Ghat stream, Hassan Abdal. Total of ninety-five fishes were caught randomly, forty-five from the unpolluted Kor...

The mixed convection heat transfer and fluid flow behaviors in a lid– driven square cavity filled with high Prandtl number fluids at low Reynolds number have been studied using Thermal Lattice Boltzmann Method (TLBM). The LBM has built up on the D2Q9 model called the Lattice-BGK (Bhatnagar–Gross–Krook) model. The Lattice Boltzmann momentum and energy equations are considered simultaneously to s...

Recently virtual reality (VR) systems have been incorporating rich information available in the real world into VR environments in order to improve their reality. This stream has created the field of mixed reality which seamlessly integrates real and virtual worlds. This paper describes a novel approach to the construction of a mixed environment. The approach is based on capturing the dynamic r...

Riparian habitats of boreal forests are considered as hotspots for biochemical processes and biodiversity, varying width riparian buffers have been proposed to protect species diversity the forests. However, evidence role soil moisture variation in shaping biodiversity ecosystem functioning remain scarce particularly regarding belowground diversity. We studied how distance from stream zone affe...

A 50-year coupled atmosphere-ocean model integration is used to study sea surface temperature (SST) and mixed layer depth (h), and the processes which influence them. The model consists of an atmospheric general circulation model coupled to an ocean mixed layer model in ice-free regions. The midlatitude SST variability is simulated fairly well, although the maximum variance is underestimated an...

introductionmany aspect strongly influence regional climate includes localized surface processes, large-scale patterns, especially mid and upper level tropospheric circulation and many factors control precipitation in the west of iran includes location of emigrate westerly winds systems, jet streams location, humidity flux and topography. upper tropospheric jet stream constitutes a significant ...

A quantitative analysis of the effects of variable ®ber properties on the performance of a cross̄ow hollow ®ber gas separation module is presented. The effects of variations in size, permeance, and selectivity are considered. Fiber variability is detrimental to performance. The recovery and ̄ow rate of an enriched retentate stream decrease as variability increases. Some ®bers may actually stop p...

We address the problem of segmentation and recognition of sequences of multimodal human interactions in meetings. These interactions can be seen as a rough structure of a meeting, and can be used either as input for a meeting browser or as a first step towards a higher semantic analysis of the meeting. A common lexicon of multimodal group meeting actions, a shared meeting data set, and a common...
