We describe an interactive system, called PILOT, for testing computer science concepts. The strengths of PILOT are its use as an algorithm visualization tool, its ability to test algorithmic concepts, its support for graph generation and layout, its automated grading mechanism, and its ability to award partial credit to proposed solutions and give meaningful feedback where appropriate. We also ...

The non-verbal communication of clinicians has an impact on patients’ satisfaction and health outcomes. Yet medical students are not receiving enough training on the appropriate non-verbal behaviors in clinical consultations. Computer vision techniques have been used for detecting different kinds of non-verbal behaviors, and they can be incorporated in educational systems that help medical stud...

Among the many issues in the ongoing national discussion about the Internet is its use in the voting process. Because voting determines who runs the government and entails two absolute requirements—the secret ballot and security from fraud—the stakes are higher than for many other transactions routinely conducted via the Internet. Public confidence about Internet security is increasing, but man...

Effective measures to prevent infections from occupaonal exposure of healthcare workers to blood include mmunization against HBV, eliminating unnecessary injections, implementing Universal Precautions, eliminating needle recapping and disposing of the sharp into a sharps container immediately after use, use of safer devices such as needles that sheath or retract after use, provision and use of ...

INTRODUCTION The Auckland chlamydia pilot project was one of three funded by the Ministry of Health to trial implementation of the 2008 Chlamydia Management Guidelines. Chlamydia is the most commonly notified sexually transmitted infection in New Zealand. AIM To increase opportunistic testing in under-25-year-olds and to improve documentation of partner notification in primary care. METHODS...

Advances in Information and Communications Technology (ICT), particularly the so-called Web 2.0, are affecting all aspects of our life: How we communicate, how we shop, how we socialise, how we learn. Facilitating learning through the use of ICT, also known as eLearning, is a vital part of modern educational systems. Established pedagogical strategies, such as Problem Based Learning (PBL), are ...

We investigate the use of repeaters to combat the problem of pilot pollution in IS-95 CDMA systems. For the purpose, we have formulated the problem into a manageable optimization model and suggested a greedy-type algorithm that determines the number and locations of repeaters needed. Simulation studies have been carried out by applying the algorithm to an actual CDMA network in which pilot poll...

The paper validates the feasibility of automating the setting of common pilot power in a WCDMA radio network. The pilot automation improves operability of the network and it is implemented with a control software aiming for load and coverage balancing. The control applies measurements of base station total transmission power of neighboring cells and terminal reports of received pilot signal lev...

This paper validates the feasibility of automating the setting of common pilot power in a WCDMA radio network. The pilot automation improves operability of the network and it is implemented with control software aiming for load balancing while also assuring pilot coverage. The pilot power of a cell is periodically updated with a gradient descent method that minimizes a cost function. The cost f...
