This paper presents a digital resolved acceleration control method for coordinated motion control of an underwater vehicle equipped with manipulators. Using this method, in spite of large position and attitude errors of the underwater vehicle, good control performances of the end-tips of the manipulators to follow a pre-planned trajectory can be achieved. In this work, theoretical work of the p...

This paper presents a method for evaluating the relative empathic ability of different characters. The method is based on the premise that human actors are able to give more compelling performances when acting opposite a more empathic acting partner. The method involves causing one or more human actors to engage in a short interaction with each character, videotaping these performances, showing...

Preliminary note The industry is under increasing pressure of the financial crisis, global competition, stricter environmental legislation and supply-chain demand. To tackle these issues, a sustainable development trend has to be assured synergetically on all the levels/fields, including machining processes. This paper promotes sustainable production via an improvement of machining technologies...

In order to obtain political interest in road safety problems and to learn from other countries’ ‘good practices’, it is often helpful to compare one’s own safety situation with that of other countries. In a number of projects tools have been developed for such comparisons. These tools range from simple ratings of countries on their safety outcomes, such as the annual number of fatalities per c...

Planning a construction project through breaking the project down into smaller individual operations of construction processes relies on an accurate estimate of the operational productivity. A model (based on 212 real construction operations) which is capable of producing such estimates is utilised to experiment with operational performance, through varying the number of resources involved in t...

Transfer of learning occurs when learning in one context enhances (positive transfer) or undermines (negative transfer) a related performance in another context. Transfer includes near transfer (to closely related contexts and performances) and far transfer (to rather different contexts and performances). Transfer is crucial to education, which generally aspires to impact on contexts quite diff...

Serious Games are recognized as one of the most promising innovative learning technologies in the short-medium term. Even if it is wide recognized the empowerment of learning they provide, there are few means to trace and measure learners‘ performances during game sessions. This paper describes a Competence Performance Analyser tool that keep trace of the players‘ activity in the shape of event...

In the present study, mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used to assess the population structure and genetic relationships among six Persian sturgeon, Acipenser persicus populations from south Caspian Sea along the Iranian coast. The complete nucleotide dehydrogenase subunit 5 (NADH 5) region of mtDNA amplified by PCR was di...
