This paper presents an approach we have recently developed for multi robot cooperation It is based on a paradigm where robots incrementally merge their plans into a set of already coordinated plans This is done through exchange of informa tion about their current state and their future actions This leads to a generic framework which can be applied to a variety of tasks and applications The para...

In this paper, estimation and tracking of the propagation delays, also known as code acquisition and tracking, in an asynchronous DS-CDMA system are considered. Of special interest is the performance in a near-far environment and the proposed estimator is shown to be near-far resistant. The suggested technique is subspace based and relies on recursively tracking the signal subspace, followed by...

Performance orientation in the development process of parallel software is motivated by outlining the misconception of current approaches where performance activies come in at the very end of the development mainly in terms of measurement or monitoring after the implementation phase At that time major part of the development work is already done and performance pitfalls are very hard to repair ...

Based on canonical correlation analysis the iteratively re-weighted multivariate alteration detection (MAD) method is used to successfully perform unsupervised change detection in bi-temporal Landsat ETM+ images covering an area with villages, woods, agricultural fields and open pit mines in North RhineWestphalia, Germany. A link to an example with ASTER data to detect change with the same meth...

Nepal has long aspired to graduate from the Least Development Country (LDC) Developing category as defined by United Nations system. had met two of three graduating criteria and could have technically graduated LDC status in 2015. However, based on government’s request defer review, new 2021 assessment Committee for Policy (CDP) recommended that country should 2026. The graduation requires not ...

The adaptive matched filter is one of the most widely used algorithms for target detection in hyperspectral imaging applications [1]. However, due to the linearity of the decision surface, there are certain types of spectra that may lead to false alarms. In this paper, we exploit the geometrical structure of the matched filter and the replacement target model to develop a procedure which, when ...

Abstract : Video streaming demands high data rates and hard de−lay constraints, and it raises several challenges on to−day’s packet−based and best−effort internet. In this paper, we propose a simple multiple−description coding (MDC) technique based on sub−sampling and cubic−spline interpolation to provide spatial diversity, such that no additional buffering delay or storage is required. Analysi...

In this paper we informally explain a new Trellis model that incorporates colored tokens into the previously described timed Petri net based de nition We give ex amples of using Trellis to de ne protocols for Computer Supported Cooperative Work CSCW We then explain an interesting analog to procedure call we have devel oped for subdocument invocation in collaborative hy perdocuments Trellis prot...
