An increase in the permissible initial window size of a TCP connection, from one segment to three or four segments, has been under discussion in the tcp-impl working group. This document covers some simulation studies of the effects of increasing the initial window size of TCP. Both long-lived TCP connections (file transfers) and short-lived web-browsing style connections were modeled. The simu...

A new method of kernel density estimation with a varying adaptive window size is proposed. It is based on the socalled intersection of confidence intervals (ICI) rule. Several examples of the proposed method are given for different types of densities and the quality of the adaptive density estimate is assessed by means of numerical simulations. 2002 Elsevier Science B.V.

In this paper we present a method to predict the window size when determining the local granulometry for a structural texture image set. The proposed method is based on the concept of periodicity property of structural texture images. It suggests that one may choose the minimum odd number not less than the maximum periods of texture images as a window size. q 1998 Elsevier Science B.V. All righ...

Event sequences often contain continuous variability at different levels. In other words, their properties and characteristics change at different rates, concurrently. For example, the sales of a product may slowly become more frequent over a period of several weeks, but there may be interesting variation within a week at the same time. To provide an accurate and robust “view” of such multi-lev...

An algorithm for image noise-removal based on local adaptive window size ¿ltering is developed in this paper. Two features to use into local spatial/transform-domain ¿ltering are suggested. First, ¿ltering is performed on images corrupted not only by additive white noise, but also by imagedependent (e.g. ¿lm-grain noise) or multiplicative noise. Second, used transforms are equipped with a varyi...

A design analysis of a telecentric microchannel relay system developed for use with a smart-pixel-based photonic backplane is presented. The interconnect uses a clustered-window geometry in which optoelectronic device windows are grouped together about the axis of each microchannel. A Gaussian-beam propagation model is used to analyze the trade-off between window size, window density, transisto...

Recognizing human activities in a sequence is a challenging area of research in ubiquitous computing. Most approaches use a fixed size sliding window over consecutive samples to extract features— either handcrafted or learned features—and predict a single label for all samples in the window. Two key problems emanate from this approach: i) the samples in one window may not always share the same ...

An investigation of the critical behavior strongly interacting quantum chromodynamics (QCD) matter has been performed by analyzing fluctuation observables on event-by-event (ebe) basis measured in high-energy collision experiments. The analysis is using nuclear interactions at different target sizes and colliding beam energies as a function varying width pseudorapidity interval. For sake compar...

We propose an adaptive random access algorithm for mobile environments with capture. The algorithm has a dynamic window size which is updated according to the tra$c intensity. The packet arrival rate is tracked by employing sequential detection procedures. Simulations indicate that reducing the window size adaptively under heavy load conditions improves the average delay signi"cantly. Copyright...

This paper provides information on extreme value modeling of stream flow extremes from three rivers in the New York City Metropolitan Area using generalized extreme value distribution (GEV). GEV parameters including location, scale, and shape are analyzed to get an appropriate minimum window size for stationary conditions, and then the time series analysis of GEV parameters are performed by usi...
