For a linear varying-parameter helicopter control system, the model reference adaptive control law is designed and an adaptive compensator is used for improving its self-re- pairing capability. To enhance anti-interference capability of helicopter, quantum control feedforward is added be- tween fault and disturbance. Simulation results illustrate the effectiveness and feasibility of the approach.展开更多

The nonlinear compensator based on functional link neural network is used to deal with the engine nonlinearity and the hardware-in-loop simulation is also developed. The results show that the nonlinear MRAC controller has the adequate performance of compensating and adapting nonlinearity arising from the change of engine state or working environment. Such feature demonstrates potential practical applications of MRAC for aeroengine control system.展开更多

These studies contributed to the development of sports sunshine, but there is also a lack of rigorous logical theory discussed, and the lack of institutional mechanisms for research, such as lack of a single research methods. Strengthening sunshine sports promotion model, the development of long-term mechanism research, both theoretical study sports sunshine depth development needs, but also a necessary requirement for the development of Sunshine Sports. In order to effectively promote the College “sunshine sports” to carry out and improve the physical health of college students, the use of literature, interviews, statistics and other research methods, sports curriculum University under the “sunshine sports” Perspectives issues the study. Sunshine Sports is a strong push forward by the Chinese government, the students physical health of government intervention measures. Activities three years, in all types of schools at all levels to actively carry out an hour a day exercise, teachers and students to participate in sports initiative, growing consciousness, awareness and physical exercise generally improved, exercise one hour a day has become common practice. But in some places there is still not know the place, lack of investment, lack of teachers and other issues, in order to make sustainable development the sun sports, will take in institution building, reform the examination and evaluation mechanisms, strengthening supervision and so do efforts.展开更多

It did function well in early years, however, as time goes by, some defects emerge and introducing a new theory to protect humarL rights conditions is necessary. Responsibility to protect evolves from right to interfere and overcomes the deficiencies inherent in its predecessor. But responsibility to protect is not a perfect system, and to improve it, some measures such as establishing a performance evaluation mechanism should be adopted.展开更多

Methods In this open-label study, patients aged 40-75 years were randomized to receive conventional therapy alone, or with Cilostazol 100 mg bid, or with Probucol 250 mg bid, or with both in combination. Endpoints included changes in plasma biomarker and safety at 12 weeks. Results Of the 200 randomized pati- ents, 165 for per-protocol and 160 for the safety （QTc intervals） were set, respectively. Probucol significantly reduced total cholesterol （P 〈 0.001）, low-density lipoprotein cholesterol （LDL-C）, （P = 0.01）, and high-density lipoprotein cholesterol （HDL-C） （P 〈 0.001） compared with conventional therapy. Cilostazol was effective in increasing HDL-C （P = 0.002） and reducing triglycerides levels （P 〈 0.01） compared with conventional therapy. A trend towards significance was observed for the difference between conventional therapy alone and Probucol plus Cilostazol group for the change in oxidized low-density lipoprotein （Ox-LDL, P = 0.065）. No significant effects on the majority of the remaining biomarkers were found across the treatment groups. Conclusions We have confirmed that Ox-LDL could be a possible plasma atherosclerotic biomarker among the evaluated biomarkers, which reflected the synergetic effect of Cilostazol plus Probucol in patients with T2DM and ASO shown previously in preclinical studies.展开更多

Presently there are three educational paths that students may take to become a registered nurse （RN）. These are the baccalaureate degree （BS）, the associate degree （AD） and the diploma. Accelerated nursing programs are also available for people who have a baccalaureate degree in another field. Nursing education and nursing practice in the United States is regulated by each of the 50 states. The focus of nursing education is the preparation of nurses who use critical thinking skills to provide comprehensive patient-centered care to a variety of clients. It is expected that nurses will function using evidence-based practice in a culturally competent, safe manner. Nursing schools must be approved by the state in which they exist. In addition to this, most nursing schools are also accredited, a voluntary process that is done by a non-governmental association. All graduates take the same licensing exam, a computer adaptive test that is from 75 to 265 items long educated graduates were first time test takers; 85.5% passed the exam. Trends in nursing education In 2008 almost 120,000 US include a focus on evidence based practice, an emphasis on safety and quality, patient education and management of chronic conditions, genetics and genomics and the use of simulation in nursing education展开更多

Biochar application rate was at 3 to 4% of soil weight. Biochar was mixed in various proportions to come up with treatments which were 100% vermicompost, 50/50% biochar： vermicompost, 75/25% biochar： vermicompost and 100% biochar. The experiment was repeated twice and arranged as a completely randomized design and replicated five times. The study established that maize yield increased with application of biochar from 25% to 50%. In the cabbage trial, comparable results in plant height, leaf numbers and final yield was obtained with 100% vermicompost application, 50% and 75% biochar inclusion. When biochar was applied at 100%, noticeable reduction in plant performance was noted. It is recommended to use biochar as a bio-fertiliser at 50/50% biochar： vermicompost in maize and cabbage production.展开更多

This kind of system has the advantage of energy-saving. But, it also has some defects that have to be improved. Microcomputer control of a pump controlled motor electrohydraulic servo system is studied. A PID controller is first adopted on the closed loop control system, and experimental results are obtained. Then, a model reference adaptive controller is designed and realised on the same system applying a single board microcomputer. Experimental results show that the dynamic properties of the adaptive control system is much better than those of the PID system under different inertia load conditions.展开更多

However, the existing models of risk management are always built from the perspective of financial regulators and neglect the practicability within the organization. In order to better facilitate the enterprise risk management （ERM）, this paper is trying to construct a new framework of RMC system from the standpoint of the management team. The foundations of our design are COSO ERM report, as well as multi-disciplinary theories and methods, such as economy, psychology, and behavior. We establish a three-component RMC system for commercial banks, which include setting RMC standards, monitoring RMC execution, and rewarding results from standards execution. Then, we introduce an extended three-factor RMC system model. This system and its extended framework are meaningful and referential for both theory and practice of commercial banks＇ risk management.展开更多
