Question-answering systems (QAS) are presented as an alternative to traditional systems of information retrieval, intended to offer precise responses to factual questions. An analysis has been made of the results offered by the QA multilingual biomedical system HONqa, available on the Web. The study has used a set of 120 biomedical definitional questions (What is...?), taken from the medical we...

This paper analyzes a dynamic relational contract for employees with reciprocal preferences. A model of long-term employment relationship is developed that implies generous upfront wages activate the norm reciprocity and then are more important when an employee close to retirement. In earlier stages, direct incentives promising bonus in exchange effort effective. Hence, reciprocity-based reinfo...

Abstract Within the research work of Transregional Collaborative Research Center TRR 136, process signatures were determined for processes that generate essentially thermal loading component surface layer. These represent correlations between material modifications (e. g. changes residual stress, microstructure, hardness profile, etc.) and characteristic values loading. The underlying idea is d...

Extensive use of the preemergence herbicide triallate over the last three decades has selected for resistant (R) Avena fatua L. populations in several areas of the United States and Canada. R plants are also cross-resistant to the unrelated pyrazolium herbicide difenzoquat. We made reciprocal crosses between inbred R and susceptible (S) lines to determine the genetic basis of triallate resistan...

Exergy and thermoeconomic analyses are herein employed to evaluate the proposed refrigeration cycle of Tabriz olefin plant. The exergetic and exergoeconomic variables of all equipment and streams are calculated. Thermoeconomic model is developed according to the total revenue requirement (TRR) method. The results indicate that the rational efficiencies of the Heat Exchanger E-104 and compressor...

Abstract A fundamental understanding of droplet dynamics is important for the prediction and optimization technical systems involving drops sprays. The Collaborative Research Center (CRC) SFB-TRR 75 was established in January 2010 to focus on basic drop processes, particular processes extreme ambient conditions, example near thermodynamic critical at very low temperatures, under influence stron...

Resumo O Princípio da Relatividade de Galileu (PRG) estabelece que as leis mecânica são mesmas em qualquer referencial inercial. Ao determinar todos os referenciais inerciais equivalentes, esse princípio implica uma relatividade do movimento. Por outro lado, mesmo considerando o PRG como basilar para a mecânica, Isaac Newton introduz conceitos tempo e espaço absolutos apresenta argumentos, natu...
