Question answering systems aim to meet users’ information needs by returning exact answers in response to a question. Traditional open domain question answering systems are built around a single pipeline architecture. In an attempt to exploit multiple resources as well as multiple answering strategies, systems based on a multi-stream architecture have recently been introduced. Such systems face...

the effect of alkyl substituents on the c-phenyl and/or the n-phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. the predominant configuration in chcl3 is determined by steric and electronic effects. substituents on the c-phenyl ring favor the cis configuration, while substituents in the n-phenyl ring favor a trans configuration. t...

The configuration-controlled regime and the diffusion-controlled regime of conformation-modulated fluorescence emission are systematically studied for Markovian and non-Markovian dynamics of the reaction coordinate. A path integral simulation is used to model fluorescence quenching processes on a semiflexible chain. First-order inhomogeneous cumulant expansion in the configuration-controlled re...

Most algorithms in probabilistic sampling-based path planning compute collision-free paths made of straight line segments lying in the configuration space. Due to the randomness of sampling, the paths make detours that need to be optimized. The contribution of this paper is to propose a gradient-based algorithm that transforms a polygonal collisionfree path into a shorter one, while both: • req...

ABSTRACT Existing studies show that occupants’ behavior contribute to fluctuations in energy consumption of residential units within the same building configuration. Window blinds are one interior design elements occupants use control indoor environmental conditions. The way adjust their could affect performance buildings. Thus, purpose this research was identify spatial and temporal explanator...

Near-equiatomic NiTi alloys are known to exhibit a thermoelastic B2–B19? martensitic transformation, which gives rise their unique properties of the shape memory effect and pseudoelastic effect. This transformation can be induced by application stress. The stress-induced nucleates locally randomly within body material, making initiation propagation unpredictable. In addition, occurs often in Lü...

In the past, terahertz spectroscopy has mainly been performed based on time-domain systems in a transmission or window/prism-supported reflection configuration. These conventional approaches have limitations regard to characterizing opaque solids, conductive thin films, multiple-layer structures, and anisotropic materials. Ellipsometry is self-reference characterization technique with wide adap...

chemical hardness (), absolute electronegativity (), and electrophilicity () have importantapplications in inorganic chemistry. these concepts are defined quantitatively as � � �� � ����,� � �� � ����, � � ������where i is the ionization energy and a is the electron affinity. in thisstudy, graphical method was used to see the relation of electron configuration with chemicalhardness, absolute...

a tandem agv configuration connects all cells of a manufacturing area by means of non-overlapping, sin-gle-vehicle closed loops. each loop has at least one additional p/d station, provided as an interface between adjacent loops. this study describes the development of three tabu search algorithms for the design of tandem agv systems. the first algorithm was developed based on the basic definiti...
