The container-loading problem aims to determine the arrangement of items in a container. We present GRMODGRASP, a new algorithm for the CLP based on the GRASP (greedy randomized adaptive search procedure) paradigm. We evaluate GRMODGRASP'S performance in terms of volume use and load stability and by comparing it with nine well-known algorithms. Our approach(More)
In this paper we report on the acquisition and content of a new database intended for developing audiovisual speech recognition systems. This database supports a speaker dependent continuous speech recognition task, based on a small vocabulary, and was captured in the European Portuguese language. Along with the collected multi-modal speech materials, the(More)
In this paper, the design of intelligent agent is discussed. This agent is used to percept the changes in the environment and changes the expression of 3D human face using 3D morphing. The design is proposed for implementation in Java 3D API. Type of intelligent agent is a simple reflex agent and it has four functions, the first is to percept the change in(More)
Feature extraction for automatic interpretation of EEGs has been extensively studied. A number of commercial approaches use exotic feature sets such as wavelets or nonlinear statistical measures such as fractal dimension. These choices of features were the results of evaluations and optimizations conducted on small research databases often collected under(More)
The " Capuchin research community roundtable: working together towards a comparative biology of Cebus and Sapajus " was held at the International Primatological Society Congress in Cancún, Mexico, August 2012. Goals of the roundtable were to strengthen interactions among the capuchin research community, and to prioritize and coordinate research and training(More)
In this paper we studied the phonemic structure of the words' beginnings and endings in standard European Portuguese (hereafter EP). The generativist description of the Portuguese phonology [1] was used as framework basis and the phonetic and acoustic experiments performed by Delgado-Martins [2] served as a model to the phonetic background in EP. We also(More)

In this poster we report on the motivations, acquisition and contents of a new database intended for developing audiovisual speech recognition systems dedicated to assistive technology applications. 1. INTRODUCTION The main motivations for the work carried out constructing the speech database here presented can be expressed through the two following(More)
The present paper describes the work done during the last year in the development of European Portuguese (EP) speech recognition and synthesis channels for an Internet e-commerce application. The objective of this work was to develop the appropriate speech input and output, to enable the user to more comfortably use an e-commerce web site issuing commands(More)
