Clinical dose calculations are often performed by scaling distances from a dose distribution measured in one medium to calculate the dose in another. These perturbation calculations have the mathematical form of a mapping. In this paper we identify five conditions required for particle transport to reduce to this form and develop a new mapping for ...

Mapping trasmembrane distribution of sphingomyelin
Emerging Topics in Life Sciences, 2023Our knowledge on the asymmetric distribution of sphingomyelin (SM) in the plasma membrane is largely based on the biochemical analysis of erythrocytes using sphingomyelinase (SMase). However, recent studies showed that the product of SMase, ceramide, disturbs transmembrane lipid distribution.

Distributed probabilistic map service
Proceedings of the 41st IEEE Conference on Decision and Control, 2002., 2003Maps are a good representation of the information state of a network-centric multi-vehicle system that tracks targets. The map service uses information pushed to it by sensors to compute a probabilistic map, i.e., the conditional density of the location of targets given all the past observations. We have designed the map service to be distributed, i.e.

Distributed Multirobot Exploration and Mapping
Proceedings of the IEEE, 2006Efficient exploration of unknown environments is a fundamental problem in mobile robotics. We present an approach to distributed multirobot mapping and exploration. Our system enables teams of robots to efficiently explore environments from different, unknown locations.

Sample distribution shadow maps
Symposium on Interactive 3D Graphics and Games, 2011This paper introduces Sample Distribution Shadow Maps (SDSMs), a new algorithm for hard and soft-edged shadows that greatly reduces undersampling, oversampling, and geometric aliasing errors compared to other shadow map techniques. SDSMs fall into the space between scene-dependent, variable-performance shadow algorithms and scene-independent, fixed ...

A Distributed Virtual Network Mapping Algorithm
2008 IEEE International Conference on Communications, 2008Network visualization is a promising concept to diversify the future Internet architecture into separate virtual networks (VN) that can support simultaneously multiple network experiments, services and architectures over a shared substrate network.

A fast distributed mapping algorithm
1990Generating an efficient program for a parallel computer requires that the distribution of the processes on the processors comprising the parallel computer is most optimal. This paper presents a new method for a load balanced and communication optimized process distribution onto an arbitrary processor (network) topology.

A mapping method for distributed heterogeneous systems
1994We present a method to characterize a distributed program for evaluating processes to processors allocation strategies in a heterogeneous computing system. The method is based on a Generalized Stochastic Petri Net model of the given hardware/software configuration. The model is used to compute various performance indices, depending on the nature of the
