    On the Flow-level Dynamics of a Packet-switched Network

    The packet is the fundamental unit of transportation in modern communication networks such as the Internet. Physical layer scheduling decisions are made at the level of packets, and packet-level models with exogenous arrival processes have long been employed to study network performance, as well as design scheduling policies that more efficiently utilize network resources. On the other hand, a user of the network is more concerned with end-to-end bandwidth, which is allocated through congestion control policies such as TCP. Utility-based flow-level models have played an important role in understanding congestion control protocols. In summary, these two classes of models have provided separate insights for flow-level and packet-level dynamics of a network

    Predicting \u27Attention Deficit Hyperactive Disorder\u27 using large scale child data set

    Attention deficit hyperactivity disorder (ADHD) is a disorder found in children affecting about 9.5% of American children aged 13 years or more. Every year, the number of children diagnosed with ADHD is increasing. There is no single test that can diagnose ADHD. In fact, a health practitioner has to analyze the behavior of the child to determine if the child has ADHD. He has to gather information about the child, and his/her behavior and environment. Because of all these problems in diagnosis, I propose to use Machine Learning techniques to predict ADHD by using large scale child data set. Machine learning offers a principled approach for developing sophisticated, automatic, and objective algorithms for analysis of disease. Lot of new approaches have immerged which allows to develop understanding and provides opportunity to do advanced analysis. Use of classification model in detection has made significant impacts in the detection and diagnosis of diseases. I propose to use binary classification techniques for detection and diagnosis of ADHD

    Innovation strategies in central Europe: a corporate perspective

    Get PDF
    This paper seeks to outline the innovations strategies that various corporations have pursued in Central Europe over the last few decades. It will examine from a corporate perspective the scope and definition of innovation, highlighting how this has changed in today's eclectic ever changing environment. Drawing upon cases studies, this paper will highlight best practice in formulating innovation strategies within Central Europe. In conclusion, it will be argued that in spite of living in an environment where the pressure for companies to constantly reinvent some part of themselves is increasing, companies could greatly benefit from taking time to pause and consider how they can capitalise on the key lessons and best practice considerations that have arisen

    Body, Habit, Custom and Labour

    Theories in the modern age in philosophy, as well as in the discourse of the social sciences, are pervaded with the presuppositions of the dualisms of mind and world, theory and practice, private and public. These theoretical dualisms make it impossible to have an account of the interconnected nature of the experience of individuals and societies. The philosophical theoretical vocabulary to take account of the relations between these dualisms has been effaced with the legacy of Cartesian dualism. I argue that through a conceptual analysis of the body, as has been posited by Maurice Merleau-Ponty, and the related concepts of habit, custom and labour, we can reclaim some concepts that allow a mediation of these dualisms. In this article, I make a conceptual analysis of the epistemic, metaphysical and social–political interrelations between these concepts and argue for the relational role they play in our philosophical theoretical discourse

    Inconvenient marriages, or what happens when ethnic minorities marry trans-jurisdictionally according to their self-chosen norms

    The Utrecht Law Review is an open access, peer-reviewed journal. Articles published in the Utrecht Law Review are licensed under a Creative Commons Attribution 3.0 Unported License (http://creativecommons.org/licenses/by/3.0/).Initially published in The Utrecht Law Review: http://www.utrechtlawreview.org/ Volume 6, Issue 2 (June) 2010This article presents evidence of a trend in the practice of British immigration control of denying recognition to marriages which take place trans-jurisdictionally across national and continental boundaries and across different state jurisdictions. The article partly draws on evidence gleaned from the writer’s own experience of being instructed as an expert witness to provide opinions of the validity of such marriages, and partly on evidence from reported cases at different levels of the judicial system. The evidence demonstrates that decision making in this area, whether by officials or judges, often takes place in arbitrary ways, arguably to fulfil wider aims of controlling the immigration of certain population groups whose presence in the UK and Europe is increasingly seen as undesirable. However, and quite apart from the immigration control concerns underlying such actions, the field throws up evidence of the kinds of legal insecurity faced by those whose marriages are solemnized under non-Western legal traditions and calls into question respect for those traditions when they come into contact with Western officialdom

    Plasmodium falciparum has rare correlation properties

    Get PDF
    A plot of the correlation function of a given DNA sequence has certain characteristic features common to almost all organisms. One common feature is that the correlation values at distances that are multiples of three is higher than correlation values at other distances. Because of this such a correlation plot can be divided into two or three curves with different scalings. P. falciparum has a rare correlation property which is probably unique. I have analyzed genomes of many bacteria, fungi and protozoa and found that P. falciparum is the only organism whose DNA sequence correlation plot can be divided into four curves with different scalings. This property is neither shared by other species of the Plasmodium genus nor by other AT rich genomes. This could be a hint that the DNA sequence of P. falciparum has undergone certain rare mutational events.
