Data warehouses collect large quantities of data from distributed sources into a single repository. A typical load to create or maintain a warehouse processes GBs of data, takes hours or even days to execute, and involves many complex and user-de ned transformations of the data (e.g., nd duplicates, resolve data inconsistencies, and add unique keys). If the load fails, a possible approach is to...

the new competitive environment changes the paradigm of power system operation. in the transmission area, open access process provides fair accessibility for all market participants. congestion management is one of the most important side effects of this new process. this paper proposes a new approach for congestion management which is based on both active and reactive re-dispatch of the networ...

thermal modeling of an automotive cabin was performed in this paper to predict the inside cabin air temperature. to implement this task, thermal and ventilation loads were estimated and the mass and energy balance conservation equations for dry air and water vapor with considering a new parameter (air circulation ratio) as well as the balance equations of internal components of a cabin were der...

this paper describes a series of laboratory model tests on strip footings supported on unreinforced and geogrid-reinforced sand with an inside void. the footing is subjected to a combination of static and cyclic loading. the influence of various parameters including the embedment depth of the void, the number of reinforcement layers, and the amplitude of cyclic load were studied. the results sh...

Secretory defects in abnormal plasma cells, called Mott cells, that appear in lymphoid tissues of spontaneously autoimmune, "viable motheaten" (mev/mev) mice lead to deposition of immunoglobulin in RER-bound vesicles. Such vesicles have been termed Russel bodies. Cells with Russel bodies can also be observed rarely in normal animals, usually as a result of extreme antigenic loads or pathologic ...

A set of nodes and a set of consumers are given and to each consumer there corresponds a subset of the nodes Each consumer has a demand which is a load to be distributed among the nodes corresponding to the consumer The load at a node is the sum of the loads placed on the node by all consumers The load is balanced if no single consumer can shift some load from one node to another to reduce the ...

Designing algorithms for balanced allocation of clients to servers in dynamic settings is a challenging problem for a variety of reasons. We want a hashing-style solution where we given the ID of a client can efficiently find its server in a distributed dynamic environment where both servers and clients may be added and/or removed from the system in any order. The main objectives of allocation ...

This paper describes an investigation of the ability of humans to distinguish different levels of gearlever load. A test rig with a forward-backward moving gearshift lever was constructed using the typical interior dimensions of European B segment automobiles. The rig used a system of weights and pulleys to provide a load which could be varied in steps of 1%. Four reference loads were chosen wh...

A model of population structure in heterogeneous environments is described with attention focused on genetic variation at a single locus. The existence of equilibria at which there is no genetic load is examined.--The absolute fitness of any genotype is regarded as a function of location in the niche space and the population density at that location. It is assumed that each organism chooses to ...
