Redundant arrays of distributed disks (RADD) can be used in a distributed computing system or database system to provide recovery in the presence of disk crashes and temporary and permanent failures of single sites. In this paper, we look at the problem of partitioning the sites of a distributed storage system into redundant arrays in such a way that the communication costs for maintaining the ...

The temporary storage and subsequent release of water at glacial margins can cause severe flooding in downstream areas and substantially impact glacier dynamics. Alpine subglacial lakes may not be identified until they become subaerially exposed or release a jökulhlaup. We use interferometric synthetic aperture radar (InSAR) to identify and characterize three dynamic alpine subglacial lakes of ...

4. With an aim to improve the waste management, Mongolia developed the following regulations: “A rule on classification, collection, temporary storage, transportation, treatment of hazardous wastes” (2002); “Regulation and procedures on disposal and landfill of hazardous waste of business entities, and requirements on waste containers and waste disposal sites” (2006); “Methodology for calculati...

Many scientific codes can achieve significant performance improvement when executed on a computer equipped with a vector processor. Vector constructs in source code should be recognized by a vectorizing compiler or preprocessor. This paper discusses, from a general point of view, how a vectorizing compiler/preprocessor can be evaluated. The areas discussed include data dependence analysis, IF l...

In performing many complex tasks, it is necessary to hold information in temporary storage to complete the task. The system used for this is referred to as working memory. Evidence for the need to postulate separable memory systems is summarized, and one particular model of working memory is described, together with its fractionation into three principal subsystems. The model has proved durable...

The general goal of genetic studies of learning and memory is to develop and test theories that explain the animal's behavior in neuroanatomical, neurophysiological, cellular, and molecular terms. In this review we describe the role that gene targeting and other transgenic techniques have had in the study of mammalian learning and memory. We focus especially on the hippocampus, a brain structur...

This paper proposes two types of new auziliary ory. The first t y p e of the auxiliary matching store achieves high matching rate b y combining the LRU replacement algorithm and a simple match structure together. The second one achieves high match rate b y controlling strictly the number of active processes with an explicit hardware. Owing to some special characteristics of dynamic dataflow com...

This study assessed the effect of cold chain on egg quality in a model simulation post-washing processing and consumer storage. Post-washed eggs were assigned to 12 groups that simulated conditions temporary storage after washing (step 1; 7°C or 25°C for 1 day), transportation 2; 30°C 8 h), selling 3; 7°C, 4 weeks). The freshness microbial characteristics analyzed weeks. High-temperature steps ...

This paper pinpoints some of the problems faced when a computer text production model (COMMENTATOR) is to produce spontaneous speech, in particular the problem of chunking the utterances in order to get natural prosodic units. The paper proposes a buffer model which allows the accumulation and delay of phonetic material until a chunk of the desired size has been built up. Several phonetic studi...

This paper proposes an optimal algorithm for constructing the surface adjacency relation in a list of polygons extracted from 3D medical images. The discrete nature of data allows us to build this adjacency relation in a time proportional to the number of triangles T. We have payed a special attention on the memory requirements, since our method takes as input the surface extracted by the March...
