Mobile Cloud Computation Offloading Switch Based on Decision Value Model
Hao.Yuan,Changbing. Li,Maokang. Du 보안공학연구지원센터 2016 International Journal of Hybrid Information Techno Vol.9 No.9
A method had been constructed for mobile cloud computation offloading switch based on decision value model. In this method, two important ratios had been built: one is the calculation ratio which are offloaded on a proxy server completed tasks time and at the mobile node completed tasks time. Another is the calculation ratio which is offloaded on proxy server completed tasks energy and at the mobile node completed tasks energy. And then, decision value function was produced by combining with these two ratios. Finally, consider the optimization switch problem of computing tasks between different proxy servers. Experimental results show that the proposed method has a smaller time consumption and energy consumption by comparing with random offloading switch and minimum time-based offloading switch, and battery remaining of mobile node can be used rationally.

Background and Purpose Hypoxia, or ischemia, is a common cause of neurological deficits in the elderly. This study elucidated the mechanisms underlying ischemia-induced brain injury that results in neurological sequelae. Methods Cerebral ischemia was induced in male Sprague-Dawley rats by transient ligationof the left carotid artery followed by 60 min of hypoxia. A two-dimensional differential proteome analysis was performed using matrix-assisted laser desorption ionization-time-of-flightmass spectrometry to compare changes in protein expression on the lesioned side of the cortexrelative to that on the contralateral side at 0, 6, and 24 h after ischemia. Results The expressions of the following five proteins were up-regulated in the ipsilateralcortex at 24 h after ischemia-reperfusion injury compared to the contralateral (i.e., control)side: aconitase 2, neurotensin-related peptide, hypothetical protein XP-212759, 60-kDa heatshock protein, and aldolase A. The expression of one protein, dynamin-1, was up-regulatedonly at the 6-h time point. The level of 78-kDa glucose-regulated protein precursor on the lesioned side of the cerebral cortex was found to be high initially, but then down-regulated by 24 hafter the induction of ischemia-reperfusion injury. The expressions of several metabolic enzymes and translational factors were also perturbed soon after brain ischemia. Conclusions These findings provide insights into the mechanisms underlying the neurodegenerative events that occur following cerebral ischemia.

This article presents a novel precision synchronization control method and corresponding control design using adaptive jerk control (AJC) with parameter estimation to improve the synchronous performance for gantry servo system with parametric variations and unknown disturbances. Initially, cross-coupled control (CCC) is provided to realize the synchronous cooperation of two parallel permanent magnet linear synchronous motors (PMLSMs), and the coupled system model is transformed into a state-space form. Consequently, the filtered errors based on synchronous error and position tracking error are established to simultaneously guarantee that both the synchronous error and position tracking error converge to zero asymptotically. Then, AJC is proposed to handle the uncertainty. More specifically, an adaptive feedback gain is involved in the AJC for improving the robustness, without requiring a priori knowledge of the uncertainty. A novel adaptation law is introduced to update the adaptive feedback gain. Moreover, a terminal attractor is incorporated into the adaptation law to improve the convergence even with noise. Therefore, the chattering phenomenon are significantly alleviated. Meanwhile, parameter estimation is employed to address the model parametric variations. Experimental results demonstrate the efficiency and superior performance of the precision synchronization control method.
Cellular Particle Swarm Scheduling Algorithm for Virtual Resource Scheduling of Cloud Computing
Hao Yuan,Changbing Li,Maokang Du 보안공학연구지원센터 2015 International Journal of Grid and Distributed Comp Vol.8 No.3
The virtual resource scheduling is an important topic in the field of cloud computing. Based on particle swarm scheduling algorithm, this paper introduces cellular automata theory to construct a new cellular particle swarm scheduling algorithm. This approach through mathematical modeling for virtual resource scheduling of cloud computing and complete the final search configuration based on directional optimization objective function. Experimental results show that the proposed method has more excellent scheduling performance, in the case of changes in resources, can be also kept stable scheduling balance.

Based on an empirical survey in Shanghai, this study tests the effects of four domains of social quality (SQ) viz. economic security, social inclusion, social cohesion, and social empowerment on subjective well-being (SWB). The results show that home ownership and income are important determinants of SWB, though the latter is not as strong a predictor of SWB as the former. Apart from the economic determinants, social cohesion (e.g., political trust) as well as social inclusion (e.g., involvement with social and cultural organizations) can influence people"s SWB to a high degree. Additionally, social alienation and loneliness are negatively related to SWB. Even the degree to which people can express themselves freely relates directly to their SWB level. Results also show that the more people see success as a result of self-effort, the higher their SWB level.
直覺的辯證思維與天人合一的思想境界―對《周易》辯 證法本質問題的硏究

『주역』은 중국 선조들의 직관적 변증법 사상을 체계적으로 표현한 최초의 철학서이다. 중국의 옛 선조들은 “우러러 하늘의 형상을 보고 굽어 땅의 법을보며 가까이 몸에서 취하고 멀리 사물에서 취한다”는 의식을 통해 음양의 대립과 통일의 관계는 만물 변화의 근본이라는 것을 직관하였다. 그러나 『주역』 변증법의 목적은 음양의 대립과 통일의 추상적 원리를 드러내고자 함에 있는것이 아니라, 구체적 사물과 상황 아래서 발생하고 작용하는 메커니즘의 차이에 그 원리가 있음을 밝히고자 한 것이다. 그래서 『주역』의 저자는 64괘의 괘상을 가지고 음양 변화의 각종 전형적 형식을 개괄하였고, 아울러 사람들에게 구체적인 사물에 대한 직관으로 인도하여 사물의 존재와 변화의 시간성을 알게 하였다. 이것은 곧 『주역』변증법은 직관의 변증법이라는 말이다. 『주역』의 저자는 변증법 사유와 시간의 의식을 근거로 우주를 하나의 거대한 생명유기체로 이해했고 이것은 중국 철학의 천인합일 사상의 경지를 열었을 뿐만 아니라 중화 민족에게 넓고 큰 정신적 기풍을 주었다. I-Ching is one of the Greatest writings in Chinese philosophy, which deals with the intuitive dialectical thoughts. The ancient Chinese people viewed the opposition and unification of yin-yang underlying all processes as a fundamental principle of change, in the universe, in the world, and in the body. However, the concern of the book was not merely trying to reveal the principle of opposition and unification. Its goal was to make clear the relationship between mechanisms of difference occurring in various situations and change. The author of I-Ching sought to understand the changing patterns of yin-yang in the sequence of the sixty-four hexagrams and led people to know existence of things and flow of time. It means that I-Ching is based upon intuitive dialectic. It provided the intellectual framework of much of Chinese thinking in the fields like cosmology and biology and developed the idea of harmony between humans and God.
