Chunk-based mesh-pull Peer-to-Peer (P2P) streaming is being considered as the most promising approach to deliver real-time video to large scale users over the Internet. Chunk scheduling is one of the key components. Currently the majorities of chunk scheduling approaches focus on receiver side’s chunk/peer selection strategies. And most of previous research works neglect the service order and a...

In this paper we describe several results, built up over the last decade or so, that use twisted sheaves to study questions in algebra, arithmetic, and cohomology. The paper is for the most part expository and aims to collect in one place what is known about these methods, their applications, and some questions about their future. It also hopes to be a guide to a chunk of the literature, where ...

Chunk decomposition is the decomposing of familiar patterns into their component elements so that they can be regrouped in another meaningful manner. Such a regrouping is sometimes critically required in problem solving because during initial encoding the problem elements become automatically grouped into familiar chunks and this may prohibit finding a novel or efficient solution to problems [G...

Tibetan syntactic functional chunk parsing is aimed at identifying syntactic constituents of Tibetan sentences. In this paper, based on the Tibetan syntactic functional chunk description system, we propose a method which puts syllables in groups instead of word segmentation and tagging and use the Conditional Random Fields (CRFs) to identify the functional chunk boundary of a sentence. Accordin...

Abstr act. The article presents the experiments carried out as part of the participation in the Paragraph Selection (PS) Task and Answer Selection (AS) Task of QA@CLEF 2010 – ResPubliQA. Our System use Apache Lucene for document retrieval system. All test documents are indexed using Apache Lucene. Stop words are removed from each question and query words are identified to retrieve the most rele...

Method Engineering aims at providing effective solutions to build, improve and support evolution of development methodologies. Contributions, in the field of situational method engineering, aim at providing techniques and tools allowing to construct project-specific methodologies. But little research has focused on how to tailor such situational methodologies when used as organization-wide stan...

The model considered in this case study represents an implementation of the Bounded Retransmission Protocol (BRP) [4]. BRP is a data link protocol for transmitting partitioned files over unreliable channels. Each part, in the following referred to as chunk, is bounded in the number of permitted retransmissions. The underlying concept is similiar to the Alternating Bit Protocol. Each chunk conta...

Coding techniques for storage systems are gaining traction in data center (DC) applications, owing to their data survivability performance, and more recently, to their ability to mitigate traffic congestion. This paper considers stochastic allocation schedules in networks that admit bulk file requests, across three drive blocking models. We consider a block-based code and a stochastic schedulin...
