Duty cycling is an efficient mechanism to conserve energy in wireless sensor networks. Several existing duty cycling techniques have been proposed to conserve energy, but they are not able to handle the contention under dynamic traffic loads. In this paper we propose a protocol called Sender-Assisted-Receiver-Initiated MAC (SA-RI-MAC) which solves this problem without sacrificing the energy eff...
When researchers start doing a literature search, they often initially find an unmanageably large number of potentially relevant articles, and are forced to refine their searches. Faced with this information overload, prioritization offers an alternative to search refinement, by ordering the articles so that the ones most likely to be relevant are at the top of the list. Effective prioritizatio...
emergency physicians, like other specialists, are faced with different patients and various situations each day. they have to use ancillary diagnostic tools like laboratory tests and imaging studies to be able to manage them. in most cases, numerous tests are available. tests with the least error and the most accuracy are more desirable. the power of a test to separate patients from healthy one...
Energy management remains a critical problem in ad hoc networks since battery technology cannot keep up with rising expectations in wireless communications. Current approaches to energy conservation focus on reducing the energy consumption of the wireless interface either for a given communication task or during idling. However, these communication-time and idle-time approaches are not necessar...
due to increasing rate of flood risk throughout the world, including iran, it is necessary to identify and prioritize flood-contributing areas for flood control activities. in this study, a new approach on unit flood response method called “flood reduction method” was introduced which is applicable to prioritization of sub-basins for flood control activities. it was used to prioritize upstream ...
Recent work demonstrated hardware-based online malware detection using only low-level features. This detector is envisioned as a first line of defense that prioritizes the application of more expensive and more accurate software detectors. Critical to such a framework is the detection performance of the hardware detector. In this paper, we explore the use of both specialized detectors and ensem...
This paper presents a framework for cost-optimal HTN planning. The framework includes an optimal algorithm combining a branch-and-bound with a heuristic search, which can also be used as a near-optimal algorithm given a time limit. It also includes different heuristics based on weighted cost estimations and different decomposition strategies. The different elements from this framework are empir...
In vitro high-throughput screening (HTS) assays are seeing increasing use in toxicity testing. HTS assays can simultaneously test many chemicals but have seen limited use in the regulatory arena, in part because of the need to undergo rigorous, time-consuming formal validation. Here we discuss streamlining the validation process, specifically for prioritization applications. By prioritization, ...
