-The increasing demand for content is straining operator’s networks, thereby necessitating development of alternative content delivery mechanisms. Distributed caching architectures constitute a promising solution for mitigating the effects of demand growth by placing popular content files in proximity to users, rather than in a central site. The goal is to reduce the server load by serving as m...

This chapter describes how intelligent tutoring systems (ITS) can be used for assessment. It begins by describing intelligent tutoring systems and distinguishing them from an older, more widely available technology. It argues that this newer technology has some intrinsic benefits as a tool for assessment. It then describes a particular type of assessment widely used in the ITS community. The as...

One of the challenges to understand the organization of the nervous system has been to determine how axon guidance molecules govern axon outgrowth. Through an unbiased genetic screen, we identified a conserved Wnt pathway which is crucial for anterior-posterior (A/P) outgrowth of neurites from RME head motor neurons in Caenorhabditis elegans. The pathway is composed of the Wnt ligand CWN-2, the...

In any safety engineering effort, deriving safety requirements is a key activity. Doing this for autonomous systems (AS) is challenging. However, several existing techniques can be pulled together to create a reasonable approach The risk of interaction between implemented requirements remains a concern, as does ambiguity about the appropriate boundary of the AS system. We believe these issues c...

BACKGROUND Despite awareness that comparative analysis of patient safety data from several data sources would promote risk reduction, there has been little effort to establish an incident classification system that is generally applicable to patient safety data in European primary care. OBJECTIVE To describe the development of a patient safety incident classification system for primary care. ...
