28 Mar 2011TL;DR: A new topology construction algorithm called A3Cov is introduced, based on the A3 protocol, which increases the coverage ratio considerably compared to the original version and is evaluated jointly with four topology maintenance techniques to determine the influence of the different maintenance schemes on the area coverage and the network lifetime.
Abstract: Topology control is a well-known strategy to save energy and extend the lifetime of wireless sensor networks. It consists of topology construction and topology maintenance algorithms. While topology construction builds a reduced topology, topology maintenance changes the reduced topology when the current one is no longer optimal. The selection of an appropriate topology maintenance technique is rarely included in the evaluation of topology control solutions, even though the impact of such decision in the lifetime of the network (in terms of number of nodes or coverage) has been shown before. This paper makes two important contributions. First, it introduces a new topology construction algorithm called A3Cov, based on the A3 protocol, which increases the coverage ratio considerably compared to the original version. Second, the A3Cov protocol is evaluated jointly with four topology maintenance techniques to determine the influence of the different maintenance schemes on the area coverage and the network lifetime. The results show that the dynamic global topology maintenance techniques with A3Cov provide the best coverage and network lifetime for a substantially longer period of time compared to the ACOS protocol.

TL;DR: The Gas-Solid Vortex Reactor (GSVR) as discussed by the authors was designed to decrease the residence time of the pyrolysis vapors, thus, the secondary cracking reactions are reduced, to enhance the segregation of the char and the unreacted biomass and to improve the heat transfer rate.

TL;DR: Various algorithms that search for the best adjustments among all available contingency recovery resources, including transfers of multiskilled employees between different store areas are developed, showing that in the worst scenario, the proposed model's schedule adjustments reduced lost profits due to unexpected variations by 18%.

TL;DR: In this article, the prevalence level of reading disabilities is established in 7-year old children belonging to 4 middle class private non-bilingual schools in the district of Barranquilla.
Abstract: This article shows research preliminary results, in which the prevalence level of reading disabilities is established in 7-year old children belonging to 4 middle class private non-bilingual schools in the district of Barranquilla. The assessment tools used for this study were CEPA, Abbreviated WISC-R and ENI (Neuropsychological Children Evaluation). The reading disabilities prevalence level was determined to be, in this study, of 3.32%
