TCP’s congestion window controls the number of packets a TCP flow may have in the network at any time. However, long periods when the sender is idle or application-limited can lead to the invalidation of the congestion window, in that the congestion window no longer reflects current information about the state of the network. In this paper we propose a simple modification to TCP’s congestion co...

A new simple form window with the application of FIR filter design based on the exponential function is proposed in this article. An improved window having a closed simple formula which is symmetric ameliorates ripple ratio in comparison with cosine hyperbolic window. The proposed window has been derived in the same way as Kaiser window, but its advantages have no power series expansion in its ...

The optimal window, the time limited sequence whose energy is most concentrated in a nite frequency interval is related to a particular discrete prolate spheroidal sequence. The optimal window is actually a family of windows with many degrees of freedom. The Kaiser window is an approximation to this optimal window. Kaiser used this approximation because the standard method employed to compute t...

An abstract of the dissertation of Jin Li for the Doctor of Philosophy in Computer Science presented October 17, 2008. Title: Window Queries over Data Streams Evaluating queries over data streams has become an appealing way to support various stream-processing applications. Window queries are commonly used in many stream applications. In a window query, certain query operators, especially block...

The X Window System is introduced with a history of its development and its concepts. Current implementations and uses of the X Window System are discussed, with a survey of the most popular tools that make X easier to work with for the developer and the user alike; followed by a brief survey of what the future might be holding for X.

We propose a robust method for estimating the time-varying spectrum of a non-stationary random process. Our approach extends Thomson's powerful multiple window spectrum estimation scheme to the time-frequency and timescale planes. The method reenes previous extensions of Thomson's method through optimally concentrated window and wavelet functions and a statistical test for extracting chirping l...

This document specifies an optional standard for TCP to increase the permitted initial window from one or two segment(s) to roughly 4K bytes, replacing RFC 2414. It discusses the advantages and disadvantages of the higher initial window, and includes discussion of experiments and simulations showing that the higher initial window does not lead to congestion collapse. Finally, this document prov...

Window inference is a transformational style of reasoning that provides an intuitive framework for managing context during the transformation of subterms under transitive relations. This report describes the design for a prototype window inference tool in Isabelle, and discusses possible directions for the final tool.

This paper introduces a scheme for data stream processing which is robust to batch duration. Streaming frameworks process streams in batches retrieved at fixed time intervals. In a common setting a pattern recognition algorithm is applied independently to each batch. Choosing the right time interval is tough — a pattern may not fit in an interval which is too short, but detection will be delaye...

Abstract The paper illustrates how econometricians practice their subject, using primarily graphical tools. It is based on software which exploits the Windows operating system to show data, results, reports, and graphics simultaneously on screen, and seeks to capture the interactions which were used in the associated lecture to highlight the learning process involved in econometric modelling. T...
