This paper presents a simple and fast solution to the problem of finding the time variation of n contact forces that keep an object under equilibrium while one of the n contact forces is removed/added from/to the grasp. The object is under a constant perturbation force, like for instance its own weight. It is assumed no acceleration of the object during the regrasp operation, as well as the kno...

This paper shows the application of robust control techniques to a solar plant integrated in an air conditioning system. Different structures in an specific loop are applied, because of the complexity of the whole system. Besides the classical feedback loop, the plant controller includes also a feed forward one to reject measurable disturbances as radiation. The design methodology and some simu...

The development of high performance controllers capable of dealing with both tracking control and disturbance rejection has attracted considerable attention. This paper investigates the twodegree-of-freedom control structures with a disturbance observer and command feedforward control, respectively, and presents a double-loop control structure. The proposed control structure allows intuitive an...

AIMS The present study demonstrates the practical relevance of the concepts of transformational leadership as a Director of Nursing working with structure (shared governance) and active processes, informed by action research, to achieve the incremental breakthroughs associated with culture change in nursing. BACKGROUND Responding to the context of a decade of health reforms in a New Zealand t...

Some aspects of the use of learning control for improved performance in robot control systems are studied. The learning control signal is used in combination with conventional feedback and feed-forward control. The eeects of disturbances, unmodeled dynamics and friction are studied theoretically and in simulations of a simpliied model of a robot arm. Convergence and robustness aspects of the ch...

To enhance the tracking accuracy of servo control system of a testing platform, the AC servo control system digital controller based on DSP is designed, and the structure and the working principle of the system are introduced in this article. For system hardware, TMS320F28335 is the control core, and for the software, complex control strategy of PID control and feed-forward control is adopted. ...

background: we aimed to analyze the effect of nursing strategies on patients with chronic renal failure (crf) undergoing maintenance hemodialysis (mhd) treatment by puncturing on arteriovenous fistula (avf). methods: ninety-two patients with chronic renal failure undergoing maintenance hemodialysis (mhd) between jan 2014 and jan 2015 were included in the study (all undergoing avf, dialysis for ...

background: nurses are the main members in nursing cares and nursing managers can improve their clinical competency by applying better leadership skills. this study carried out to determine the effect of nursing management program on clinical competency of nurses in a coronary care unit (ccu). methods: a quasi-experimental study was carried out in two educational hospitals in yazd- iran. these ...

The Cochrane Collaboration is an international nonprofit organization dedicated to increasing access to high-quality evidence on the effects of health care treatments. In the spring of 2009, the Cochrane Collaboration created a new international network specific to the field of nursing, bringing the total number of Cochrane networks to 16. Cochrane networks are interest groups that provide supp...

BACKGROUND Nursing project management is widely used in different aspects of the society. However, whether the nursing project management can control the infections in the operation room (OR) is rarely reported. We evaluated the outcomes of surgical patients after implementing a nursing project management program to provide new scientific ways to manage the OR infections. METHODS Overall, 382...
