The Semantic Web project [2] aims to add semantics to the existing World Wide Web. We propose an extension of the Web’s user interaction experience to take advantage of the added semantics. This user experience maintains the Web’s original navigation paradigm, although all URIs, not just URLs, can be used to address information objects. URIs form the superset of URLs and can name resources othe...

Let f , U and C represent, respectively, the free energy, the internal energy and the specific heat of the critical Ising model on the square M×N lattice with periodic boundary conditions, and f∞ represents f as M,N → ∞. We find that f , U and C can be written as: N(f −f∞) = ∑ ∞ i=1 fi/N 2i−1, U = − √ 2+ ∑ ∞ i=1 ui/N 2i−1 and C = 8 π lnN+ ∑ ∞ i=0 ci/N i andNf and U are well-defined odd function...

Welfare evaluation of a policy that alters the quality of a resource can often be cast as the problem of calculating mean Willingness to Pay (WTP) in a population of consumers with random utilities induced by varying tastes and budgets. This interpretation is particularly useful when some of the components of choice at the level of the individual are discrete. This paper reviews the theory of W...

Neuroimaging studies have identified multiple scene-selective regions in human cortex, but the precise role each region plays in scene processing is not yet clear. It was recently hypothesized that two regions, the occipital place area (OPA) and the retrosplenial complex (RSC), play a direct role in navigation, while a third region, the parahippocampal place area (PPA), does not. Some evidence ...

Agility and fast reaction to changes is required in today’s turbulent manufacturing environment. Unfortunately, the commonly used user interfaces (UIs) on the factory floor don’t support such rapid reaction. Even though the human involvement improves agility and reactivity of production systems, it is also a source of uncertainty, especially when it comes to information inputting. Therefore, sp...

A process-planning model (PP model) is proposed to convert the geometric features into manufacture machining operations and sequence the machining operations of the part in a feasible and effective order. The process-planning model (PP model) construct a feature framework that makes a mapping from geometric features into machining operations. A semantic net named the Precedence-Relations-Net is...

since the staffing are the most important and valuable assets in organization, and achieving organizational goals depends on the commitment and expertise of its human capital, the identification and analysis of issues that impede the flourishing of this valuable asset and led them to be indifference; has a special importance. the aim of this study was analysis of the effect of job characteristi...

introduction: mental stress is one of the most important causes of the gastric ulcer. on the other hand, flavonoids such as quercetin show protective effects. the aim of this study was to investigate possible protective effect of quercetin on water restraint stress-induced ulcer in rats. methods: adult male wistar rats were divided into seven groups each containing eight animals. the first grou...
