Objectives: This paper describes further improvement and preliminarily evaluation of a novel viscoelastic ankle-foot prosthesis prototype. The objective was to control the ankle hysteresis at slow and normal walking speeds. Methods: Inspired by the ankle biomechanics, in which the hysteresis differs based on the gait speeds, a manually damping control mechanism imbedded in the prosthesis for...

Abstract The k -nearest neighbor ( NN) rule is one of the best-known distance-based classifiers, and usually associated with high performance versatility as it requires only definition a dissimilarity measure. Nevertheless, NN also coupled low-efficiency levels since, for each new query, algorithm must carry out an exhaustive search training data, this drawback much more relevant when consideri...

La primera part l'anàlisi defineix un conjunt d'estratègies control amb enfocament disseny multinivell basat una configuració específica creuada avançada assistida ventila...

Archaeological excavation documentation poses several challenges to spatial data management. This work gives a data model, respective query functionality and the description of the resulting prototype system for recording and analyzing the data produced during the course of an excavation. Based on a requirements analysis, we develop a data model that not only captures georeferenced finds (potte...

This paper designs an intelligent guidance system, based on wireless sensor networks, for efficient parking in parking lots. The proposed system consists of a parking space allocation subsystem, a parking space monitoring subsystem, a driving guidance subsystem, and a vehicle detection subsystem. In the system, we propose a novel and effective virtual coordinate system for sensing and displayin...

Case assignment is one of the most important issues in theoretical linguistics. The goal of this paper is to describe both syntactic and semantic bases for case assignment in terms of Prototype theory [1, 2] and to give an explanation for the difference in case assignment between English and Japanese by examining the Instrument Subject construction and deverbal nouns. English allows the structu...
