I. Porteous has shown that the Cayley projective plane can be coordinatized in a way resembling homogeneous coordinates. We will show how to construct line coordinates in a similar way. As an illustration, we give an explicit example to show that the Cayley projective plane is not Desarguean.

Search is a ubiquitous behavior for a variety of species. Converging evidence from several domains suggests that there may be common principles that apply to search processes regardless of the species, or contexts, in which they are observed. Theories of cognitive or memory search have been motivated by findings in the animal foraging literature, and have recently been the subject of increased ...

In coordinate metrology, evaluating task specific measurement uncertainty can be difficult, a problem which prompted the current development of several related standards at the national and international levels. Software that processes coordinate data can be an important, but often overlooked, component of measurement uncertainty. This paper describes the historically significant role software ...

This paper proposes a method to infer bloggers’ residential areas. Identifying bloggers’ residential areas will be useful as another axis to retrieve weblogs or for tasks that resolve ambiguous objects in terms of geographic contexts. Our method focuses on the local context of geographic location terms and uses binary classifiers to decide whether the context is indicating the writer’s resident...

The main problem studied in this paper is how to design an efficient method for information brokerage in sensor networks that do not use an overlay layer to organize the network and when geo-coordinates are not provided. We present a method for the solution of this problem using Directional Random Walks (DRWs) which main purpose is to construct a straight path of relaying nodes in the network. ...

Geosensors networks are dense wireless networks of small, low-cost sensors, which collect and disseminate environmental data of a vast geographical area. These networks hold the promise of revolutionizing sensing in a wide range of application. Despite the large amount of research in this field, little effort has been done to establish how to deal with the data collected by these networks. This...

Like any other complex communications infrastructure, the network connecting different locations of virtual classes in university systems has developed over time with differing combinations of synchronous and asynchronous communication technologies at the various university locations. This research focuses on graduate nursing students’ satisfaction with the learning experience in seven distinct...

This research asked the research question: what competencies and capabilities are required by HEIs engaging in e-learning? E-learning capabilities deployed in all of the cases studied in this research were a part of, or related to, existing capabilities. The findings also enable an analysis of e-learning competence. A competency is a capability performed relatively well, and confers competitive...
