This report describes the work done by the RFIA group at the Departamento de Sistemas Informáticos y Computación of the Universidad Politécnica of Valencia for the 2005 edition of the CLEF Question Answering task. We participated in three monolingual tasks: Spanish, Italian and French, and in two cross-language tasks: spanish to english and english to spanish. Since this was our first participa...

This paper describes an attempt to identify case gapping instances of Japanese relative clauses, and disambiguate the case slot from which the gapping occurred. The method utilised relies principally on surface syntactic pattern matching, combined with adjunct-based verb classification and minimal semantic analysis of the head. Experimentation produced an 90% accuracy in identifying and disambi...

Microstructure freeform surface is a type of freeform surfaces which is widely used in optical-mechanical-electronic components with increasing high precision requirement. This paper presents the characterization of structured freeform surfaces based on a pattern matching analysis method. The method employed rough matching by micro-structure features and then precise matching based on least squ...

In this paper, a new pattern based optical tracking method is presented for the recognition and pose estimation of input devices for virtual or augmented reality environments. The method is based on pencils of line fiducials, which reduces occlusion problems and allows for single camera pattern recognition and orientation estimation. Pattern recognition is accomplished using a projective invari...

In this work, we have calculated ab initio the structural and electronic properties of both the Cand Si-terminated SiC (100) surfaces in the c(2!2) and (2!1) reconstruction patterns, respectively. Based on our results, we found that the Si-terminated surfaces is dominated by weak bonded Si-dimers, which is stabilized only at Si-rich conditions, leading to a (3!2) or more complex reconstruction ...

In this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. The objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. We develop a warp...

Surface speckle pattern intensity distribution resulting from laser light scattering from a rough surface contains various information about the surface geometrical and physical properties. A surface roughness measurement technique based on the texture analysis of surface speckle pattern texture images is put forward. In the surface roughness measurement technique, the speckle pattern texture i...

Surface electromyography (sEMG) signals are closely related to the activation of human muscles and the motion of the human body, which can be used to estimate the dynamics of human limbs in the rehabilitation field. They also have the potential to be used in the application of bilateral rehabilitation, where hemiplegic patients can train their affected limbs following the motion of unaffected l...
