Adaptive Probabilistic Flooding for Multipath Routing

In this work, we develop a distributed source routing algorithm for topology discovery suitable for ISP transport networks, that is however inspired by opportunistic algorithms used in ad hoc wireless networks. We propose a plug-and-play control plane, able to find multiple paths toward the same destination, and introduce a novel algorithm, called adaptive probabilistic flooding, to achieve this goal. By keeping a small amount of state in routers taking part in the discovery process, our technique significantly limits the amount of control messages exchanged with flooding -- and, at the same time, it only minimally affects the quality of the discovered multiple path with respect to the optimal solution. Simple analytical bounds, confirmed by results gathered with extensive simulation on four realistic topologies, show our approach to be of high practical interest.Comment: 6 pages, 6 figure

Piaget for dance educators: A theoretical study

Most individuals who spend serious time with children recognize that children are not simply small versions of adults. Not only are their bodies different, but they also think differently. The dance educator, just like other educators, must attempt to see the world from the child's point of view if the teaching-learning process is to be successful. One framework for conceiving the world from the child's point of view comes from Jean Piaget, a scientist who was interested in the development of cognitive skills used in science — ordering, classifying, inferring, thinking in propositions, and hypothesizing. Such skills are important not only in science, but in any logical use of the intellect. Inasmuch as dance educators claim interest in the child's intellectual as well as emotional and physical self, an understanding of Piaget's theories may generate valuable insight. Yet neither Piaget nor his many followers who have applied his theories to specific areas of education have examined dance education through this lens. The major purpose of this paper is to “translate” Piaget's findings into situations encountered by the dance educator, and to demonstrate the usefulness of this framework in making sense of children's behavior in the dance setting. Sections I-III are designed as much for the practitioner as the researcher in dance education; I submit apologies to those for whom a review of Piaget's theory is tiresome. It will be noted that this is not an empirical study, but I hope it may direct empirically minded researchers into fruitful areas of study in dance education. It must also be noted that many of Piaget's conclusions have been questioned by more recent researchers using different kinds of situations for observation. My own concerns regarding Piagetian theory relate less to the validity of specific observations than to larger limitations of this framework in relation to dance education. A second purpose of this paper is to briefly explore those limitations

Contextual Influences on Associations between Impulsivity and Risk-Taking and Child Delinquency

Previous literature has shown that risk factors for delinquency include individual characteristics of impulsivity and risk-taking as well as contextual influences such as neighborhoods, parenting and engagement in physical activity (e.g., exercise, sports). Theory suggests that individual characteristics interact with contextual factors to influence child development, however evidence is limited. The current study examined the interaction between these individual and contextual risks to influence childhood delinquency in a community sample of 89 children ranging from 9 to 12 years of age (M = 10.4, SD = 1.1). Questionnaire measures showed that both caregiver report of impulsivity and self-reported risk-taking were positively associated with self-reported delinquency, yet no interactions with contextual factors were found. When using computer tasks, neither impulsivity nor risk-taking were significantly associated with delinquency. However, a risk-taking by physical activity interaction was found, such that at low levels of physical activity risk-taking was positively related to delinquency, yet at high levels of physical activity, risk-taking and delinquency were unrelated. Thus, programs that involve physical activity may be useful prevention and intervention strategies for risk-taking children

The exploration of concepts for projectile toys

Includes bibliographical references (p. 199-200).Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, September 2005 (first author); and, (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, June 2006 (second author).(cont.) The second concept, eDarts, involved incorporating a capacitor powered micro-circuit and LED into foam darts similar to those used in the current line of Nerf® products. The eDarts created a tracer shot or laser bullet" effect when used in low light conditions. Safety, projectile mass, and axially symmetric loading were the greatest issues of concern. The final suggested eDart incorporated a standard DC power connection with a simple mechanical switch. The eDarts reached comparable distances to the current foam darts on the market. while maintaining a safe Kinetic Energy Density.The goal of this research has been to develop new concepts for foam projectile toys. The team followed a standard design practice and brought two unique concepts to an alpha-prototype level. Through brainstorming sessions the team generated over 100 concepts of which the sponsor selected twelve high potential concepts for first order prototyping. Of these prototypes, the team chose two concepts worthy of refinement and further development. The operational principles of the highest potential concepts were thoroughly analyzed and developed through a series of prototypes. The first concept, Hopper Popper Activation, involved using a bi-stable rubber spring to propel foam balls. This concept created a simple, space-saving, and effective means of storing energy. The hopper popper was implemented in several devices, the most successful being a small hand held toy called the Hand Popper. The greatest issue of concern with the Hopper Popper Activated concepts was the force required to load the toy. The final design implemented a low friction system with a ball guiding channel to reduce this loading force. The final design required a lower operational force than the comparable product on the market, while capable of propelling foam balls 20% further.by William J. Fienup and Barry M.
