Constraint Propagation can be speeded up significantly by choosing a good execution order for propagators. A propagator is an implicit representation of a constraint which is widely used in todays powerful constraint solvers. In this paper we evaluate different ways to find good execution orders automatically during runtime. We extend previous work in this area by two new techniques: fair-sched...

This is the first study to attempt to explain income inequality using unemployment and inflation and international cross-sectional data. Using a SURE system, inflation is found to have an increasing impact on the shares of the lower 80% of the income distribution, while reducing the share of the highest 20%. Unemployment has a negative effect on the share of the first 40%, while increases the s...

The aim of this paper is to investigate the effect of the Chinese B share market reform on the correlation and information transmission between A and B Shares issued in the Shanghai and Shenzen stock exchanges. Daily returns for the Shanghai A share index (SHA), Shanghai B share index (SHB), Shenzen A share index (SZA) and Shenzen B share index (SZB) are used for the period 6 October 1992 to 8 ...

We present a novel approach to wireless fair scheduling in a distributed architecture. Our scheme is based on a simple extension of wireline fair scheduling by compensation for lost capacity after the losses occur. In addition, the scheduler can give limited compensation for unused capacity. This provides an incentive for users of the location-dependent wireless channel to optimize their channe...

Acquiring accurate and timely market share information is very important for producers to arrange producing plan and design marketing strategy. However the high cost and long period of collecting survey data in survey-based method make it much difficult to easily get latest market shares data. Recently, the emerging online web systems provide users with new and convenient ways of searching, lea...

Abstract Query execution techniques in database systems constantly adapt to novel hardware features achieve high query performance, particular for analytical queries. In recent years, vectorization based on the Single Instruction Multiple Data parallel paradigm has been established as a state-of-the-art approach increase single-query performance. However, since concurrent queries running often ...
