Multisensor data fusion is a technique that combines the readings of multiple sensors to detect some phenomenon. Data fusion applications are numerous and they can be used in smart buildings, environment monitoring, industry and defense applications. The main goal of multisensor data fusion is to minimize false alarms and maximize the probability of detection based on the detection of multiple sensors. In this paper a local data fusion algorithm based on luminosity, temperature and flame for fire detection is presented. The data fusion approach was embedded in a low cost mobile robot. The prototype test validation has indicated that our approach can detect fire occurrence. Moreover, the low cost project allow the development of robots that could be discarded in their fire detection missions. © 2013 IEEE.

The Economic Commission for Latin America and the Caribbean (ECLAC) Subregional Headquarters for the Caribbean, in collaboration with the Division of Production, Productivity and Management at ECLAC Headquarters in Chile, convened a one-day workshop on “Boosting SME Development and Competitiveness in the Caribbean”, at the Subregional Headquarters for the Caribbean in Port of Spain on 14 May 2009. The workshop was the culmination of country studies that were carried out under an Italian Government-funded project to assess the policies, institutions and instruments for dynamic Small and Medium Enterprises (SME) development and competitiveness in Jamaica, Suriname and Trinidad and Tobago. The aim was to use the lessons learned from the three country studies to inform policy and practice in the other member countries of the Caribbean Development and Cooperation Committee (CDCC). The main objectives of the workshop were to: (a) share and discuss the findings of the country studies and lessons learned; (b) provide a forum for high quality discussion of the policy environment, instruments, business development and support services required for successful SME development in the Caribbean; and (c) map out a strategy for moving from analysis and recommendation to policy implementation and business changes in order to promote a dynamic and competitive SME sector. The workshop aimed to arrive at practical solutions to major constraints and a weighting of key actions in order of priority of implementation, by adopting a problem-solving approach. Participants at the workshop included representatives of key SME support institutions in the region, actual SMEs and academic researchers. The list of participants and provisional programme are annexed to this report.

This report examines the usage of digital currency technology in the Caribbean subregion with a view to drawing attention to the opportunities and risks associated with this new phenomenon. It discusses the broader context of an emerging activity at the global level and considers how this technology could address subregional deficiencies in the electronic payment infrastructure. The report also discusses mobile money solutions, and the relationship of that technology to digital currency.

The oil and gas sector has led the economy of Trinidad and Tobago since the late 1970s and, more pronouncedly, since 2000, accounting for a large share of gdp, total exports and tax revenue. Its prospects in the medium term could be negatively affected, however, if oil and gas extraction expands in other countries, and if the United States attains energy self-sufficiency. This paper offers an analysis of the evolution and competitiveness of its oil and non-oil exports to both the United States and global markets, based on the revealed comparative advantage (rca) index used by eclac. Other foreign trade indicators are also included to determine the structure of the country’s trading relations. The period from 1985 to 2010 is analysed and the results presented are intended to advocate the diversification of Trinidad and Tobago’s exports into more dynamic and diversified markets.

ABSTRACT: In this paper we present the synthesis and simulation of alkynes derivatives. Semiempirical calculations were carried out for the ground and first excited states, including the spectroscopic properties of the absorption and emission (fluorescence and phosphorescence) spectra by INDO/S-CI and DNdM-INDO/S-CI methods with geometries fully optimized by PM3/CI. The fact that the theoretical spectra are in accord with the experimental absorption spectra gives us a new possible approach on how structure modifications could affect the non-linear optical properties of alkynes.

O envelhecimento é um processo dinâmico e progressivo que se caracteriza pela ocorrência de modificações morfológicas, bioquímicas, funcionais e psicológicas do organismo. O objetivo do presente artigo é fornecer conceitos atualizados sobre estresse oxidativo, abordando sua importância no envelhecimento, assim como o estado nutricional e suplementação com antioxidantes (substâncias que evitam ou atenuam a oxidação de substratos oxidáveis, como lipídeos, proteínas, carboidratos e o ácido desoxirribonucleico) na população geriátrica. Evidências sugerem que existe uma relação inversa entre estresse oxidativo e estado nutricional em indivíduos idosos. Embora seja comprovado o aumento do estresse oxidativo nas doenças crônicas associadas ao envelhecimento, como doença de Parkinson e doença de Alzheimer, não há, até o momento, evidências clínicas consistentes que comprovem a eficiência da suplementação com antioxidantes contra o estresse oxidativo. Nesse contexto, a suplementação não é recomendada. Por outro lado, idosos devem ser encorajados a ingerir alimentos antioxidantes, como, por exemplo, frutas e vegetais. A manutenção do peso dentro da faixa de normalidade (índice de massa corpórea entre 23 e 28 kg/m2) também deve ser estimulada.

This study aims to evaluate and correlate the vascular, sensory and motor components related to the plantar surface in individuals with diabetic peripheral neuropathy. 68 patients were categorized into two groups: 28 in the neuropathic group and 40 in the control group. In each patient, we assessed: circulation and peripheral perfusion of the lower limbs; somatosensory sensitivity; ankle muscle strength; and pressure on the plantar surface in static, dynamic and gait states. We used the Mann-Whitney test and analysis of variance (ANOVA and MANOVA) for comparison between groups, and performed Pearson and Spearman linear correlations amongst the variables (P < 0.05). The somatosensory sensitivity, peripheral circulation and ankle muscle strength were reduced in the neuropathic group. In full peak plantar pressures, no differences were seen between groups, but differences did appear when the foot surface was divided into regions (forefoot, midfoot and hindfoot). In the static condition, the plantar surface area was greater in the neuropathic group. In the dynamic state, peak pressures in the neuropathic group, were higher in the forefoot and lower in the hindfoot, as well as lower in the hindfoot during gait. There were positive or negative correlations between the sensitivity deficit, dorsal ankle flexor strength, plantar surface area, and peak pressure by plantar region. The sensitivity deficit contributed to the increased plantar surface area.

Companies that invest in current technologies maintain themselves updated, improve their business rules and anticipate themselves against rivals providing a better service to their customers. This project aims to develop an ERP - Enterprise Resource Planning module for Android which complements an existing manager system and, that attends the needs of a rental equipment business for civil building, i.e., it improves the communication channel company-client and betters the identification and control of products. During the developing of this project, it was necessary to study the company business rules, analyze the requirements and the appropriate technologies. This project was organized in two parts, contemplating e ach of these needs. It were implemented specific modules for generate budgets and pre-orders in the first part and, the use of radiofrequency tags in the second one. Thus, it was possible to assign mobility to company business rules so that a better rental service can be provided and the equipments can be better managed
