Prognozowanie Wpływu Motoryzacji Na Poziom Stężenia Ozonu W Przyziemnej Warstwie Atmosfery, Marek Bogacki, Marian Mazur, Robert Oleniacz

Robert Oleniacz

The paper presents an approach for assessing the impact of road transport on the level of ozone concentrations in the ground layer of the atmosphere. The developed method consists in emission inventory on the analyzed area for road transport and calculations using the model of chemical reactions in the troposphere.

Using this method it is possible to display waveforms daily ozone concentrations in the air, and evaluate the effectiveness of the decisions related to the prevention of occurrence of photochemical smog in urban and industrial agglomerations.

English title: Predicting the impact of motoring on the level of ozone concentration in …

On The Benefit Of Supporting Virtual Channels In Wormhole Routers, Richard Cole, Bruce Maggs, Ramesh Sitaraman

Ramesh Sitaraman

This paper analyzes the impact of virtual channels on the performance of wormhole routing algorithms. We study wormhole routing on network in which each physical channel, i.e., communication link, can support up to B virtual channels. We show that it is possible to route any set of messages with L flits each, whose paths have congestion C and dilation D in O((L+ D) C(D log D)1_B_B) flit steps, where a flit step is the time taken to transmit B flits, i.e., one flit per virtual channel, across a physical channel. We also prove a nearly matching lower bound; i.e., for …

A Control Basis For Multilegged Walking, Manfred Huber, Willard S. Macdonald, Roderic Grupen

Roderic Grupen

This paper presents a distributed control approach to legged locomotion that constructs behavior on-line by activating combinations of reusable feedback control laws drawn from a control basis. Sequences of such controller activations result in flexible aperiodic step sequences based on local sensory information. Different tasks are achieved by varying the composition functions over the same basis controllers, rather than by geometric planning of leg placements or the design of new task-specific behaviors. In addition, the device-independent nature of the control basis allows its generalization not only over task domains, but also over different hardware platforms. To show the applicability of …
