This paper deals with the experimental identification of the dynamic parameters of the C5 parallel robot. The inverse dynamic model of the robot is formulated under the form of linear equation with respect to the dynamic parameters. Moreover, a heuristic procedure for finding the exciting trajectory has been conducted. This trajectory is based on Fourier series whose coefficients are determined...

This contribution is concerned with the value of RFID for retail store operations, particularly the use of the technology to automate shelf replenishment decisions. We construct and test an inventory control policy based on RFID data with case-level tagging. Our model incorporates RFID hardware capable of detecting bidirectional product movements between a store's backroom and the sales floor. ...

Automated essay marking systems developed from late 1960’s attempted to prove that a computer can mark essays as good as any other human beings. This paper discusses an approach for developing an automated marking tool for English as a second language (ESL) and introduces heuristics and rulebased approach to detect grammatical errors in tenses in ESL essays. The results show that heuristics and...

This paper presents the results of some experiments on using a simple algorithm, aided by a few heuristics, for the purposes of language identification on Twitter data. These experiments were a part of a shared task focused on this problem. The core algorithm is an n-gram based distance metric algorithm. This algorithm has previously been shown to work very well on normal text. The distance met...

This paper proposes a method to solve the conflicts that arise in the framework of fuzzy model identification with maximal rules [1] where rules are selected as general as possible. This resolution is expressed by including exceptions in the rules, that way achieving a higher model interpretability with respect to other techniques and a more accurate model. Besides, several methods are presente...

Various word-processing system have been developed to identify grammatical errors and mark learners’ essays. However, they are not specifically developed for Malaysian ESL (English as a second language) learners. A marking tool which is capable to identify errors in ESL writing for these learners is very much needed. Though there are numerous techniques adopted in grammar checking and automated...

The sinusoidal magnetization of a sample material is difficult to achieve, since the magnetic hysteresis poses a strong non-linearity. In order to find the proper input voltage, a feed-forward strategy with a hysteresis model identification and inversion is proposed. The classical Preisach model in the Everett formulation is used for this purpose and eddy current effects are also included. A ne...
