Various approaches to providing blind users with access to graphical user interfaces have been researched extensively in the past 15 years, and yet accessibility is still facing many obstacles. Graphical environments such as X Windows offer a high degree of freedom to both the developer and the user, complicating the accessibility problem even more. Existing technology is largely based on eithe...

This paper uses a market potential approach to examine the evolution of the rail transport network of China and its spatial distributional impacts on local accessibility, with a particular focus on high-speed rail improvements. Accessibility is measured by using a “market potential” function that was derived from the general equilibrium model of the economic geography literature, and is empiric...

Solvent-accessible surface areas of residues in proteins are key factors in protein folding. Predicting solvent accessibility from protein sequences is significant for modeling the structural and functional characteristics of many proteins. In this work, we introduce an approach of enhancing solvent accessibility prediction accuracy. We derive pseudo-potentials, by considering high-orderinter-r...

When does procedural unfairness result in retaliation, and why do recipients of unfair treatment sometimes pursue and other times inhibit retaliation? Five studies addressed these questions. The authors proposed and found that regulatory focus moderates retaliation against an unfairness-enacting authority: Promotion-focus participants were more likely to retaliate than prevention-focus particip...

An opportunistic network (OPPNET) consists of diverse mobile nodes with various mobility patterns. Numerous mobility patterns and the resource constraints of mobile nodes lead to network partitioning that result in system performance degradation including low data accessibility. In a traditional mobile ad hoc network (MANET) which is similar to an OPPNET, replica allocation schemes have been pr...

The article describes methods for dealing with reliability and fault tolerance issues of cloud datacenters. These methods are mainly focused on the elimination of single point of failure within any component of the cloud infrastructure, including the availability of infrastructure and accessibility of cloud services. The methods for providing the availability of hardware, software and network c...
