Distributed wireless systems offer several advantages over their traditional wired and centralized counterparts, e.g., flexibility, easy installation, reconfiguration, and scalability. Although the resources in these distributed systems are often limited in order to achieve costeffective operation, the concept of distributed system design is in the focus of intensive research even in those appl...

Papua New Guinea is one of the 14 highest-burden countries for tuberculosis (TB) infection, but few community-based studies exist. We evaluated a low-cost method of active community case finding in Kabwum and Wasu in Morobe Province, Papua New Guinea. Over 3 months we visited 26 villages and screened adults and children for symptoms and signs of TB. Sputum samples were examined using smear micr...

This paper introduces a monitoring problem with limited energy resources and soft constraints on priorities employing a fleet of unmanned aerial vehicles (UAVs). This monitoring problem is a generalization of application cases ranging from surveillance of open-air events to monitoring crime scenes or disaster sites. In order to compute solutions, we propose an insertion heuristic with a negotia...

Semantic standardization is an integral part of sharing data for GIS and spatial analysis. It is part of a broader rubric of interoperability or the ability to share geographic information across multiple platforms and contexts. GIScience researchers have made considerable progress towards understanding and addressing the multiple challenges involved in achieving interoperability. For local gov...

Automatic recognition of continuously-spoken digits (e.g., telephone numbers or credit card numbers) is feasible with excellent accuracy, even for speaker-independent applications over telephone lines. However, even such relatively simple recognition tasks su er decreased performance in adverse conditions, such as signi cant background noise or fading on portable telephone channels. If an appli...

CMYK 511 lesions (infarcts), in the absence of supratentorial involvement or antecedent illness indicated posterior circulation stroke as the aetiology. The distribution of these ischemic lesions was multifocal, in the areas supplied by left superior cerebellar, left anterior inferior cerebellar and the penetrating left pontine branches of basilar arteries, thus involving the middle and distal ...

We describe an experiment in rapid development of a statistical machine translation (SMT) system from scratch, using limited resources: under this heading we include not only training data, but also computing power, linguistic knowledge, programming effort, and absolute time.

In categorization tasks where resources such as time, information, and computation are limited, there is pressure to be accurate, and stakes are high – as when deciding if a patient is under high risk of having a disease or if a worker should undergo retraining –, it has been proposed that people use, or should use, simple adaptive heuristics. We introduce a family of deterministic, noncompensa...
