In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...

This paper discusses an approach, which allows classifying videos by frequencies. Many videos contain repetitive activities like walking, swimming, or playing table tennis. These activities usually repeat with a certain frequency, which can be seen as a feature of cyclic motion. So determining this feature can help to classify videos with repeating movements properly. In this paper we explain h...

Overhead athletes often suffer shoulder and elbow injuries. More often than not these arise insidiously without any obvious trauma. The usual culprit is cumulative overload or repetitive strain. Weight lifting exercises (e.g. lateral deltoid raise, military press, dips, regular or incline barbell press), throwing overhand (e.g. baseball, football), or hitting overhead (tennis serve or overhead,...

Technology has helped improve rehabilitation programs by providing patients with engaging alternatives to otherwise monotonous and repetitive exercises. In recent years, therapists have looked towards multi-touch technologies to further enhance patient rehabilitation programs. So far, the focus has mainly been on single-user interaction, largely ignoring many of the benefits patients receive fr...
