importance of sediment storage has been expressed as being higher than that of water in floodwater spreading networks. to determine the contribution of each geological formation in sediment input of gachsaran floodwater spreading station after 12 years of flood spreading, sediment sampling was conducted in 16 points and 0-15 cm depth of the field. using dry sieve analysis, all samples were anal...

MIS researchers have developed a number of models for studying the software utilization choices of end users, including the Task-Technology Fit Model and the Technology Acceptance Model. We are exploring the similarities and differences among these models with a goal of developing combined models with more explanatory power. This paper proposes a model that extends the task-technology fit model...

Project management software packages are increasingly used by companies. These tools require a substantial financial investment, hence the importance of identifying the real contribution of project management software packages to the realisation of projects. However, studies on the impacts of software packages on the performance of engineering project management are rare and mostly based on per...

Land use change is a major threat to global biodiversity. Forest species face the dual threats of deforestation and intensification of forest management. In regions where forests are under threat, rural landscapes that retain structural components of mature forests potentially provide valuable additional habitat for some forest species. Here, we illustrate the habitat value of traditional wood ...

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...

zeinab fatemi amin phd student (economic sociology and development) majid fouladiyan phd student (theoretical cultural sociology) the main issue in this paper is two-way causal relationship between educational efficiency in any country and the development in society; it means while education in any society is affected by different levels of development, also as a independent variable influences...

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...
