  • 공리적 설계는 미국 매사추세츠 공과대학의 서남표 교수에 의해 창출되고 보급되어 온 설계이론이다. 그러나 좀 더 정확히 말한다면 설계이론 이라기보다는 일반적인 공학적 과정에 적용할 수 있는 원리를 포함하는 설계프레임워크라 할 수 있다. 기계공학에서의 역학과 같이 설계를 하기 위해서는 과학적인 기본원리에 따라 설계해야 한다는 것이다. 그러므로 공리적 설계는 설계과정에서 설계자에게 과학적 원리를 제공하여 설계자가 이성적이고 논리적으로 설계를 진행할 수 있도록 하여, 시행착오를 줄이며, 좀 더 창조적이고 최상의 설계를 선택할 수 있도록 도움을 주는 것이다.(중략)

  • The Sexual Function Study and Its Rehabilitation Of the Patients With Spinal Cord Injuries Park Ji Whan, R.P.T. Dept. of Rehabilitation Medicine, nanyang University Hospital The patient with complete spinal cord injuries cannot expect normal intercourse. In spite of these ultimate limitations. coitus is practied with gratification by about a third of paraplegic men. and probably a higher percentage of paraplegic women. Th-is is possible since a significant percentage of paraplegic men can have erections .In patients with upper motor neurone lesions at any spinal level, reflex erections can be produced by local stimulation , in. patients with lesions at higher levels, the probability of success is greater. The ability to have erections, psychic or reflex or both, usually appears within six months after injury .

  • Sensing and coverage are the two relevant tasks for a sensor network. Quality of sensor network totally depends upon the sensing ability of sensors. In a certain monitored region success of detecting or sensing an object with the help of sensor network tells that how efficiently the network coverage perform. Here in this paper we have proposed a clustering algorithm for the deployment of sensors and thus calculated the object detection probability. Actually by this work we can easily identify the present network coverage status and accordingly can take action for its improvement.

  • The accuracy of contingency estimation plays an important role for dealing with the uncertainty of the financial success of construction project. Its' estimation may be used for various purposes such as schedule control, emergency resolve, and quality expense, etc. This paper presents a contingency estimation method which is schedule control specific. The method 1) implements stochastic EVMS, 2) detects a specific timing for schedule compression, 3) identifies an optimal strategy for shortening planned schedule, 4) finds a probability density function (PDF) of project cost overrun, and 5) estimates the optimal contingency cost based on the level of confidence. The method facilitates expeditious decisions involved in project budgeting. The validity of the method is confirmed by performing test case.

  • One-shot device is required to successfully perform its function only once at the moment of use. The reliability of a one-shot device should be expressed as a probability of success. In this paper, we propose a bayesian approach for estimating reliability of one-shot devices with small sample size. We employ a gamma prior to obtain the posterior distribution. Finally, we compare the accuracy of the proposed method with general maximum likelihood method.

  • This research is implement of a counselling cases search system for improving the effectiveness of student-counselling through internet with teachers experience which is obtained in school. This system is consisted of manager module and user module. User module can use student-counselling search and input, a bulletin board, reference data etc., and manager module offers manage function for a data and the membership. The counselling cases search system is able to improving in success probability of student-counselling. Because teacher can share easily their remote area they counselling cases through using internet.

  • Recently a new regime, called "back school" is advocated for the purpose of rapidly and economically returning a patient to full functional fitness and normal occupational activities. Assuming that this functional and vocational restoration is a goal of a regabilitation program, it is apparent that early recovery and higher success rate are major concern. In this study, a mixture model is developed and used to evaluate the recovery process of low back pain (LBP) patients in a rehabilitation program. The model provides (1) the probability of being recovered, and (2) the rate of recovery. Patients with gradual onset, with higher education, or of young age tend to show better prognosis.

  • In the IEEE 802.15.3 Medium Access Control (MAC) protocol, Simultaneously Operating Piconets (SOPs) are linked by the parent/child (P/C) or parent/neighbor (P/N) configuration, which work on a Time Division Multiple Access (TDMA) basis. This provides interference mitigation but the overall throughput is limited because the SOPs share the channel time exclusively. The protocol is not efficient for SOPs if we focus on the combination of interference mitigation and high throughput maintenance. In this paper Public Channel Time Allocation (Public CTA) is proposed, which is able to greatly reduce the inter-piconet interference (IPI) and achieve greater throughput without much loss of link success probability (LSP) in the SOPs. The simulation results based on the SOPs of Direct Sequence Ultra Wideband (DS-UWB) system demonstrate that the proposed scheme effectively supports the coexistence of SOPs, and it can not only significantly improve the overall throughput of SOPs but also maintain high LSP.

  • This paper presents an evolvable cooperation strategy based on a genetic programming for the interactive robot soccer game. The interactive robot soccer game has been developed to allow a person to join in the game dynamically and to reinforce entertainment characteristics. In this game, a cooperation strategy between humans and autonomous robots is very important in order to make the game more enjoyable. First of all, necessary action sets for the cooperation strategy and its strategy structure are presented. In the first stage, a blocking action that an autonomous robot cut off an enemy robot from disturbing the way of the human controlled robot has been considered. The success probability of the blocking action has beer obtained in ...

  • One of the distinct features of Wireless Sensor Networks (WSNs) is duty cycling mechanism, which is used to conserve energy and extend the network lifetime. Large duty cycle interval introduces lower energy consumption, meanwhile longer end-to-end (E2E) delay. In this paper, we introduce an energy consumption minimization problem for duty-cycled WSNs. We have applied Q-learning algorithm to obtain the maximum duty cycle interval which supports various delay requirements and given Delay Success ratio (DSR) i.e. the required probability of packets arriving at the sink before given delay bound. Our approach only requires sink to compute Q-leaning which makes it practical to implement. Nodes in the different group have the different duty cycle interval in our proposed method and nodes don't need to know the information of the neighboring node. Performance metrics show that our proposed scheme outperforms existing algorithms in terms of energy efficiency while assuring the required delay bound and DSR.
