... Although there is not still a commonly accepted view on whether EHD-thrusters are worthwhile or not, what level of thrust and thrust efficiency can be obtained from these devi- ces, etc., there are surely some primary ...
... Working with a flexible foil forced by a pitching oscillation at one ex- tremity and allowed to self-propel freely along a rectilinear trajectory, we focus in the present paper on the effect of swimming near a solid ...
... these systems, among which the followings were selected, within the aim of the present work: the AVAS shall automatically generate a sound in the minimum range of vehicle speed from start up to approximately 20 ...
... Apart from congruency we are interested in finding numbers with divisibility properties. These are really important in cryptography. In particular, numbers that are only divided by either number 1 or by themselves are ...
... during propulsion (Figure 2). The ROM used during the propulsion phase was smaller in HP feet for all foot joints considered, with significantly reduced final plantarflexion angle, which might be related ...
... This module constitutes the nucleus of the Advanced Automation speciality, thus its courses are compulsory for those students pursuing expertise in this field. They will study advanced methodologies and frameworks for ...
... In language, relatively few letters of the alphabet are used to construct a large number of words. Similarly, in arithmetic, a small variety of numerals can be used to represent all numbers. One of the greatest ...
... It is obvious that we can simply define (1.6) from (1.2) and (1.5), without any extra assumption on stabilization. This is what we do in this paper. Recall that we consider the case of existence of systems of the ...
