| In this paper, we propose a fuzzy logic based control scheme for real time MPEG video to avoid long delay or excessive loss at the user-network interface (UNI) in an ATM network. The system consists of a shaper whose role is to smooth the MPEG output traac to reduce the burstiness of the video stream. The input and output rates of the shaper buuer are controlled by two fuzzy logic based contr...

Wireless communication of video, with Bluetooth as an example, represents a compromise between channel conditions, display and decode deadlines, and energy constraints. This paper proposes fuzzy logic control (FLC) of automatic repeat request (ARQ) as a way of reconciling these factors, with a 40% saving in power in the worst channel conditions from economizing on transmissions when channel err...

Intelligent congestion control is vital in encoded video streaming of a clip or film, as network traffic volatility requires constant adjustment of the bit-rate. Equation-based solutions to congestion control are prone to fluctuations in the delivery rate and may respond only when packet loss has already occurred, while both fluctuations and packet loss affect the end-user’s perception of the d...

Future generation wireless networks will demand more intelligent and adaptive handover decision mechanisms to fulfil users’ expectations in terms of seamless mobility over extensive area, min imum price, high data rate, adequate QoS provision and so on. For such a demanding networking environment the handover decision system (HDS) need to be highly intelligent. Fuzzy logic appears to be one of ...

Recently, a new server-less architecture is proposed for building low-cost yet scalable video streaming systems. Compare to conventional client-server-based video streaming systems, this server-less architecture does not need any dedicated video server and yet is highly scalable. Video data are distributed among user hosts and these hosts cooperate to stream video data to one another. Thus as n...

Abstract Persistent homology is a computationally intensive and yet extremely powerful tool for Topological Data Analysis. Applying the on potentially infinite sequence of data objects challenging task. For this reason, persistent stream mining have long been two important but disjoint areas science. The first computational model, that was recently introduced to bridge gap between areas, useful...

banks are one of the most important financial sectors in order to the economic development of each country. certainly, efficiency scores and ranks of banks are significant and effective aspects towards future planning. sometimes the performance of banks must be measured in the presence of undesirable and vague factors. for these reasons in the current paper a procedure based on data envelopment...
