Seemingly overnight, the Internet has gone from an academic experiment to a worldwide information matrix. Along the way, computer scientists have come to realize that understanding the performance of the Internet is a remarkably challenging and subtle problem. This challenge is all the more important because of the increasingly significant role the Internet has come to play in society. To take stock of the field of Internet performance modeling, the authors organized a workshop at Schloß Dagstuhl. This paper summarizes the results of discussions, both plenary and in small groups, that took place during the four-day workshop. It identifies successes, points to areas where more work is needed, and poses “Grand Challenges” for the performance evaluation community with respect to the Internet.

The purpose of this study was to determine how much art activity is taking place within households in Austin, Texas. By way of a questionnaire, the parents or guardians of children attending schools within the Austin Independent School District were surveyed regarding art activity within their homes. The objective of this investigation was to provide answers to questions such as: In what ways do children participate in art making within the context of the family household? To what extent does it appear a parent’s/guardian’s level of schooling, number of children in the family, and amount of electronic entertainment available to the child correspond with the amount of art activity that takes place in the household? Professional and personal motivations led to this investigation. There is an ever increasing amount of electronic entertainment available to children. Has this recent growth of technology had an effect on the amount of time children spend with art activities in the home? Through my own experiences growing up, and through conversations with others, it was brought to my attention that the number of children residing in a household might have an effect on the amount of art activities taking place within the home, as well as the parent’s or guardian’s level of education. Through the data collected by this investigation, I was able to reach a conclusion regarding the relationship found between the amount of art activities taking place in the households surveyed and the three variables studied in this investigation: (a) the parent’s education, (b) the amount of electronic entertainment available to the children in the home, (c) the number of children residing in the home. Support from the data indicated a significant pattern representing that the parent’s/guardian’s education is related to the amount of art activity taking place within the household. However, there was no pattern found regarding the variable of electronic entertainment devices found in a home and the amount of art making within that home. There was also a significant relationship found regarding the numbers of children residing in the household, and the amount of art activity those children are engaged in. The data collected indicated that a household in which fewer children reside is more likely to participate in more art activities. / text

Distributed Mobile Robotics (DMR) is a multidisciplinary research area with many open research questions. This is a survey of the state of the art in Distributed Mobile Robotics research. DMR is sometimes referred to as cooperative robotics or multi-robotic systems. DMR is about how multiple robots can cooperate to achieve goals and complete tasks better than single robot systems. It covers architectures, communication, learning, exploration and many other areas presented in this master thesis. / Uppsatsen är en brett spektrum på vilken forskning som pågår rörande distribuerad mobil robotik, dvs hur många robotar kan samverka för att lösa uppgifter. / Adress: Victor Adolfsson Folkparksvägen 12:24 372 38 Ronneby Telefon: 0457-171 42 Mobil: 0709-441389
