It is reported in the literature that a TCP connection with small window size achieves high throughput in wireless multihop networks. In this paper, we claim that TCP can benefit more from delaying ACK rather than limiting the window size. Since the induced delay may result in lengthy transfer time for short connections, we propose an adaptive delayed ACK algorithm at the receiver to enhance TC...

With the continuous attention of modern search engines to retrieve entities and not just documents for any given query, we introduce a new method for enhancing the entity-ranking task. An entity-ranking task is concerned with retrieving a ranked list of entities as a response to a specific query. Some successful models used the idea of association discovery in a window of text, rather than in t...

This paper presents an application of the adaptive median post-filter to improve impedance estimation based on the differential equation algorithm. The main feature of the post-filter is the automatic selection of the optimal window size that balances between fast tracking and filtering performance. For sudden impedance change (fault inception), small window size is selected to make fault detec...

Information sharing has become the basic need of time, and internet supports us to share the information in one of the fastest possible ways. Internet has emerged as the basic need of the time. Internet has influenced every part of our life. Shopping, communication, entertainment, business, information, education all aspects of one’s life are available on internet There has been a tremendous in...

This paper describes a congestion control method for TCP that adjusts the transmission rate of a TCP connection by changing not only the congestion window size as in normal TCP, but also by delaying the transmission of packets at the sender. We refer to this method as TCP with sender-based delay control, or simply SDC. SDC can keep the window size of a TCP connection above a certain threshold e...

Most of the contemporary systems assumes that all the flow of packets are same and requires O(1) buffer size for transferring packets in a network. This leads to more buffer size even for short flow of packets also, which wastes the buffer size. To overcome this problem, this paper proposes a new technique which uses different buffer sizes based on the packet flows. For long packet flows longer...

An efficient algorithm addressing robust disparity estimation based on region information is proposed. In the proposed method, a new adaptive-size window approach is introduced to stereo matching in order to overcome problems with fixed-size window. The reliability of disparity estimation is then measured with a criterion based on uniqueness and smoothness constrains. In occluded areas and imag...

For a binary pseudorandom sequence {Si} with period N , the partial period autocorrelation function AS(τ, k,D) is defined by correlating the portion of the sequence within a window of size D, and start position k, with the portion in another window of the same size but starting τ steps later in the sequence. A distribution of possible partial period autocorrelation values is obtained by allowin...

In geographically weighted regression, one must determine a window size which will be used to subset the data locally. Typically, a cross-validation procedure is used to determine a globally optimal window size. Preliminary investigations indicate that the global cross-validation score is heavily influenced by a small number of observations in the dataset. At present, the ramifications of this ...

Many transcription factor binding sites (TFBSs) involved in gene expression regulation are preferentially located relative to the transcription start site. This property is exploited in in silico prediction approaches, one of which involves studying the local overrepresentation of motifs using a sliding window to scan promoters with considerable accuracy. Nevertheless, the consequences of the c...
