We apply a "sliding-window" Maximum Likelihood(ML) estimator to estimate traffic parameters On-Off source and develop a method for estimating stochastic predicted individual cell arrival rates. Based on these results, we propose a simple Connection Admission Control(CAC)scheme for delay sensitive services in broadband onboard packet switching satellite systems. The algorithms are motivated by the limited onboard satellite buffer, the large propagation delay, and low computational capabilities inherent in satellite communication systems. We develop an algorithm using the predicted individual cell loss ratio instead of using steady state cell loss ratios. We demonstrate the CAC benefits of this approach over using steady state cell loss ratios as well as predicted total cell loss ratios. We also derive the predictive saturation probability and the predictive cell loss ratio and use them to control the total number of connections. Predictive congestion control mechanisms allow a satellite network to operate in the optimum region of low delay and high throughput. This is different from the traditional reactive congestion control mechanism that allows the network to recover from the congested state. Numerical and simulation results obtained suggest that the proposed predictive scheme is a promising approach for real time CAC.

An assembly sequence is considered to be optimal when it minimizes assembly cost while satisfying assembly constraints. to generate such sequences for robotic assembly, this paper proposes a method using a genetic algorithm (GA). This method denotes an assembly sequence as an individual, which is assigned a fitness related to the assembly cost. Then, a population consisting of a number of individuals evolves to the next generation through genetic operations of crossover and mutation based upon the fitness of the individuals. The population continues to repetitively evolve, and finally the fittest individual and its corresponding assembly sequence is found. Through case study for an electrical relay, the effectiveness of the proposed method is demonstrated. Also, the performance is evaluated by-comparing with those of previously presented approaches such as a neural-netowork-based method and a simulated annealing method.

Workplace knowledge sharing is a complex process and there are a large number of studies in the area. In this article three theoretical approaches in library and information science are used to discuss knowledge sharing in the workplace. The approaches are information behavior, social capital, and information culture, and they bring important insights that need to be considered from a holistic management point of view when it comes to knowledge sharing. The individual's relation to different levels of context is important, meaning both in relation to work roles, work tasks, situations, organizational structures, and culture. The frameworks also shed light on where and how knowledge sharing activities are present in the organization. From a knowledge management point of view, it is important to acknowledge that when knowledge is valued, there is also an awareness of the knowledge sharing activities. Also, in addition to more traditional views of context, the frameworks bring forward different views on context, such as time and space as contextual factors.

The purpose of this study is to investigate the differences in individuals and family characteristics between general and vocational high school female students, and the impacts of the characteristics on the their occupational outlook. The number of 792 female students in 4 general and 5 vocational high schools in Chongju area were sampled during September 6-10, 1993. There are more differences in family characteristics rather than individual characteristics between two types of high school female students. Both family and individual characteristics influence the occupational outlooks of the respondents. Therefore, the types of school affect their occupational outlooks. Over 50% of vocational students want to have a junior college education.

Knowledge management has recently emerged as an appealing subject in management literature. Although its history is short, it can benefit greatly from the long history of other related disciplines in building its theories. Innovation, organizational learning, knowledge creation, organizational capability building, technology transfer and network, information technology, organizational behavior, and intellectual capital are the disciplines that have accumulated theories related to knowledge management. This paper first presents a conceptual framework that integrates three dimensions: the characteristics of knowledge (tacit and explicit), knowledge process (acquisition, creation, diffusion, storing, measurement, and application of knowledge), and the unit of analysis (individual, organization, sector, and nation). The conceptual framework produces a number of cells that need to be filled by new theories in order to understand knowledge management better. It then reviews existing theories available in the related disciplines that may be used as building blocks in constructing new theories for these cells. Finally, based on the theories available in other disciplines, the paper suggests a set of future research directions for knowledge management at the level of individual, organization, sector, and nation.

Many of the current buildings in Algeria were built in the past without any consideration to the requirements of the seismic code. Among these buildings, there are a large number of individual houses built in the 1980's by their owners. They are Reinforced Concrete (RC) frame structures with unreinforced hollow masonry infill walls. This buildings type experienced major damage in the 2003 (Algeria) earthquake, generated by deficiencies in the structural system. In the present study, special attention is placed upon examining the vulnerability of RC frame houses. Their situation and their general features are investigated. Observing their seismic behavior, structural deficiencies are identified. The seismic vulnerability of this type of buildings depends on several factors, such as; structural system, plan and vertical configuration, materials and workmanship. The results of the vulnerability assessment of a group of RC frame houses are presented. Using a method based on the European Macroseismic Scale EMS-98 definitions, presented in previous studies, distribution of damage is obtained.

An Arbitration agreement is one kind of contracts between two or more contracting parties; any possible disputes that arise concerning a contract will be settled by arbitration. The parties are free to agree on the number of arbitrators. The role of the arbitrator is so significant in the arbitration system that its success or failure may depend on the credibility of the arbitrator. The purpose of this paper is to examine the specific elements of the Arbitration Clause through arbitration laws, arbitration rules and the related cases, to introduce the standard clause which are recommended by the international institution and the individual countries, and to make the parties of international commercial contracts reflect them in their contracts. Thus this author would like to recommend the famous and well known the Standard Clause which were drafted by international institution such as ICC and UNCITRAL or individual countries.(LCIA, AAA, CIETAC, KCAB)

To elucidate whether small diameter at breast height correlates with tree death in an overcrowded tree population, we analyzed self-thinning occurring over the course of 37 years in naturally established Pinus densiflora populations in Sugadaira, central Japan. As trees grew, their diameters at breast height increased and the number of trees consequently decreased. Spatial distribution, which was initially clumped, changed accordingly, first becoming random and finally uniform. We calculated the "available area" of individual trees to elucidate the contribution of this parameter to tree mortality. Small diameter at breast height was strongly correlated with tree death, with a slight correlation observed between tree death and small available area of individual trees.

Objectives: Colorectal cancer (CRC) is the most commonly diagnosed cancer for all US populations including Asian Americans. CRC screening has considerable benefits to prevent CRC and reduce mortality. The purpose of this article was to review the published literature on rates of colorectal cancer screening and factors associated with colorectal cancer screening practice among Asian Americans. Methods: Through searching electronic reference databases from 2000 to 2013, 30 articles were found on Chinese, Filipino, Japanese, Korean, and Vietnamese Americans. Findings: Asian Americans had significantly low ratesfor CRC screening; Korean Americans reported the lowest rates, while higher screening rates were found among Japanese Americans. Older age, longer length of stay in the US, and having a physician's recommendation were the most common facilitators to receiving screening. The common inhibiting factors were financial issues, employment status, and worries/fears about the procedure. Conclusions: Despite a number of Asian Americans being vulnerable to CRC, individual Asian subgroups were underserved with CRC screening and intervention. Further studies should focus on each individual Asian subgroup and culturally proficient CRC screening intervention programs should be developed for each.
