Pulse shaping is a techniqueused to temporally distribute energywithin a single laser pulse. This provides the user an added degree of control over the heat delivered to the laser material interaction zone. Pulses that induce a gradual heating or a prolonged cooling effect can be generated with peak power/pulse

The method of controlled Lagrangians is a technique for stabilizing relative equilibria of mechanical systems with symmetry. This paper develops a modification of kinetic shaping technique in the theory of controlled Lagrangians. The main idea is that the dynamics associated with the controlled Lagrangian is amended by non-conservative forces that act in the shape directions; this gives additio...

The focus of this paper is the traffic shaping at the access of an network node. We propose a novel algorithm that dynamically shapes the incoming traffic, based on service curves equations, in order to meet the QoS constraints in terms of buffer size or delay. We first estimate arrival parameters within various time intervals in order to make the incoming traffic fit into a token bucket traffi...

We present a geometric formulation for the energy shaping problem. The central objective is the initiation of a more systematic exploration of energy shaping with the aim of determining whether a given system can be stabilized using energy shaping feedback. We investigate the partial differential equations for the kinetic energy shaping problem using the formal theory of partial differential eq...

The theoretic foundation of traditional microphone array postfilters is the signal model in which the noise between sensors is assumed to be uncorrelated. However, this model is inaccurate in real environments since the correlated noise exists. In this paper, a more generalized signal model which considers both the correlated and uncorrelated noise is introduced. A general expression of the mic...

Over the last decade, declining enrollments in Information Systems (IS) discipline has been a major concern for the IS community. Literature suggests that one plausible explanation for the decline in enrollments is the negative stereotypical image students hold about IS professionals. It has also been emphasized that the introductory IS course plays a significant role in busting prevailing myth...

Based on a critical analysis of the literature on the development and adoption of interorganisational information systems (IOIS) we propose a new unit of analysis for IOIS studies, define levels of analysis based on this unit in order to organize a large set of variables pertinent to the study of IOIS, and show how this design will be implemented within an international collaborative research p...

This research evaluates the accuracy of demand forecasts using a sample of recently-completed projects in Minnesota and identifies the factors influencing the inaccuracy in forecasts. Based on recent research on forecast accuracy, the inaccuracy of traffic forecasts is estimated as the difference between forecast traffic and actual traffic, standardized by the actual traffic. The analysis indic...

Congestion costs are emerging as one of the most important challenges faced by metropolitan planners and transport authorities in first world economies. In US these costs were as high as 78 million dollars in 2005 and are growing due to fast increases in travel delays. In order to solve the current and severe levels of congestion the US department of transportation have recently started a progr...
