An important issue in human robot interaction is for the robot to recognize the human agent. The problem has infinitely many application, for example surveillance [1], museums guide robots [2], car driving application [3] and many more [4] and also many problem specific solutions [5] . Apart from other application though, in rescue operation the task is even more important [5] because human age...

Sperm DNA integrity is vital for successful fertilization, embryo development, pregnancy, and transmission of genetic material to the offspring. DNA fragmentation is the most frequent DNA anomaly present in the male gamete that has been associated to poor semen quality, low fertilization rates, impaired embryo quality, and preim‐ plantation development and reduced clinical outcomes in assisted ...

Our research concerns teaching assistant systems. It deals with the question of reuse and exploitation of learners profiles by the different actors of the learning situation; teacher, learner, families, institution or scientist. This paper first describes the difficulties linked to the reuse of heterogeneous existing learners profiles. Then, REPro, a learners profiles m...

Background Development of bioprocesses for mammalian cells has to deal with different bioreactor types and scales. Bio-reactors might be intended for seed train and production, research, process development, validation or transfer purposes. During these activities, not only the problem of upand downscaling might lead to failure of repro-ducibility, but also the use of different bioreactor geome...

We show that in order to satisfy incentive compatibility the country...

Comparative analyses of educational methods have often been inconclusive; there are several possible explanations: (1) each method is optimally effective under specifically differing circumstances; (2) the studies tend to emphasize one input variable to the exclusion of the others; (3) the methods do not have widely accepted definitions; and (4) the methods are often tested before they are perf...
