this paper focuses on the effects of closed- control on the calculation of the dynamic load carrying capacity (dlcc) for mobile-base flexible-link manipulators. in previously proposed methods in the literature of dlcc calculation in flexible robots, an open-loop control scheme is assumed, whereas in reality, robot control is achieved via closed loop approaches which could render the calculated ...

abstract background: the loop colostomy is one of the most popular techniques used as a protective maneuver for a distal anastomosis and/or temporary fecal diversion. we are introducing the use of a full thickness skin bridge under the large bowel instead of a glass rod which alleviates problems such as protrusion of the large bowel, retraction of the bowel into the abdomen after removing the r...

statement of problem: t-loop is one of the most popular closing loops in orthodontic profession. however its activation is in the contrary to bouschinger effect theory, since the formed bends would be opened during activation. the purpose of this study was to add a helix in a way to be more respondent to the bouschinger effect theory. objectives: to compare the load deflection, maximal elastic ...

This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a  vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...

the cu doped nio (nio:cu) nanoparticles were synthesized by co-precipitation method using nicl2.6h2o, cucl2.2h2o for ni and cu sources, respectively. sodium hydroxide has been used as a precipitator agent. effect of cu doping agent on the structural and optical properties of nanostructures were characterized by xrd, sem, afm, spectrophotometry, ftir and vsm techniques. xrd revealed that nio:cu ...

In this paper, distributed parameter process systems behavior is studied in frequency domain. Based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. By using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...
