    The emerging widespread use of real-time multimedia applications over wireless networks makes the support of quality of service (QoS) a key problem. In this paper, we focus on QoS support mechanisms for IEEE 802.11 wireless ad-hoc networks. First, we review limitations of the upcoming IEEE 802.11e enhanced DCF (EDCF) and other enhanced MAC schemes that have been proposed to support QoS for 802.11 ad-hoc networks. Then, we describe a new scheme called adaptive fair EDCF that extends EDCF, by increasing the contention window during deferring periods when the channel is busy, and by using an adaptive fast backoff mechanism when the channel is idle. Our scheme computes an adaptive backoff threshold for each priority level by taking into account the channel load. The new scheme significantly improves the quality of multimedia applications. Moreover, it increases the overall throughput obtained both in medium and high load cases. Simulution results show that our new scheme outperforms EDCF and other enhanced schemes. Finally, we show that the adaptive fair EDCF scheme achieves a high degree of fairness among applications of the same priority level

    Pendidikan adalah suatu proses di mana suatu bangsa atau negara membina dan mengembangkan kesadaran diri di antara individu-individu. Pendidikan adalah latihan fisik, mental dan moral bagi individu-individu, agar mereka menjadi manusia yang berbudaya.

    Stigma in youth with Tourette's syndrome: a systematic review and synthesis

    Tourette's syndrome (TS) is a childhood onset neurodevelopmental disorder, characterised by tics. To our knowledge, no systematic reviews exist which focus on examining the body of literature on stigma in association with children and adolescents with TS. The aim of the article is to provide a review of the existing research on (1) social stigma in relation to children and adolescents with TS, (2) self-stigma and (3) courtesy stigma in family members of youth with TS. Three electronic databases were searched: PsycINFO, PubMed and Web of Science. Seventeen empirical studies met the inclusion criteria. In relation to social stigma in rating their own beliefs and behavioural intentions, youth who did not have TS showed an unfavourable attitude towards individuals with TS in comparison to typically developing peers. Meanwhile, in their own narratives about their lives, young people with TS themselves described some form of devaluation from others as a response to their disorder. Self-degrading comments were denoted in a number of studies in which the children pointed out stereotypical views that they had adopted about themselves. Finally, as regards courtesy stigma, parents expressed guilt in relation to their children's condition and social alienation as a result of the disorder. Surprisingly, however, there is not one study that focuses primarily on stigma in relation to TS and further studies that examine the subject from the perspective of both the 'stigmatiser' and the recipient of stigma are warranted

    But, Whatever The Reason, His Heart or His Shoes, He Stood There on Christmas Eve, Hating the Whos : Dr. Seuss\u27 The Grinch as The Racialized Other in American Culture

    This thesis analyzes Dr. Seuss’ the Grinch as a modern myth in US society that provides an imaginary resolution to the perceived encroachment of racial and cultural heterogeneity in the various time periods in which the text has circulated. Each chapter closely reads three different versions of the story, including Dr. Seuss’ children’s book published in 1957, the 1966 animated TV special directed by Chuck Jones, and the 2000 film directed by Ron Howard and starring Jim Carrey. In each chapter, I consider the racial politics prevalent in each time period in order to elucidate my claim that various media representations of the Grinch reveal American culture’s attitude towards the racialized Other. Ultimately, I argue that the Grinch functions to represent an imagined racialized Other who in each text must become acculturated in the end, thereby paralleling US cultural attitudes toward the “other” who must conform to US dominant culture

Abstraction methods are used ontologies to find clarity about the world of facts all arrive at a fundamental understanding. Fundamental knowledge produced by ontology can be used as a basis for revisiting the basic assumptions that science has assumed are established

    Knowledge Retrieval using Foon

    Flexible task planning is still a significant challenge for robots. The inability of robots to creatively adapt their task plans to new or unforeseen challenges is largely attributable to their limited understanding of their activities and the environment. Cooking, for example, requires a person to occasionally take risks that a robot would find extremely dangerous. We may obtain manipulation sequences by employing knowledge that is drawn from numerous video sources thanks to knowledge retrieval through graph search.Comment: arXiv admin note: text overlap with arXiv:1902.01537 by other authors. text overlap with arXiv:2211.0299
