  • In this paper, we present biomimetic hopping strategy which is more human-like for legged robot through stiffness modulation. Stiffness value is calculated from the motion of body center of gravity. This method enable to reduce impact force on touch-down, adaption on ground stiffness change and height modulation. Simple selected models will be used to validate this method. For general model, singular perturbation is used for control and simulation using stiffness modulation is presented.

  • When we consider a life insurance company that sells a large number of continuous T-year term life insurance policies, it is important to find an optimal strategy which maximizes the surplus of the insurance company at time T. The purpose of this paper is to give an explicit expression for the optimal reinsurance and investment strategy which maximizes the expected exponential utility of the final value of the surplus at the end of T-th year. To do this we solve the corresponding Hamilton-Jacobi-Bellman equation.

  • As microcomputers have become widespread and the high speed solenoid valves have been developed, digitally controlled hydraulic systems are used in many applications. This study deals with position control of hydraulic cylinder operated by two port 3-way high speed solenoid valve using a self-learning strategy. This was done by developing a control algorithm for the microcomputer which always automatically adjust the length of control pulse to the optimum value in accordance with the error regardless of changes in the operating condition and physical differences between components. Tests carried out in the laboratory indicate that a positional accuracy could be improved.

  • Based on an active set strategy a method for solving lin-early constrained indefinite quadratic programs to solve the correspond-ing system of equations at each iteration is presented. The algorithm takes two descent directions to strictly decrease the value of objective function and obtains a suitable step to maintain feasibility. Computa-tional results on a range of quadratic test problems are given.

  • Purpose - The postponement strategy, which delays the form, place, and production of products as late as possible, has been widely considered as a competitive supply chain management scheme in an era of mass customization and modular manufacturing. An interesting business phenomenon is that not all manufacturing/logistics firms choose the postponement strategy. Given that postponement is a counter-measure to speculation, which has some advantages under certain environments, the current imprudent inclination toward the postponement strategy may cause firms to lose the potential of the speculation strategy, an alternative strategy in supply chain management. Building on the logistics and manufacturing literature, this study examines characteristics of two contrasting strategies, postponement and speculation, and major factors favoring each strategy. Research design, data, and methodology - We apply the profiling approach to two business cases, HP printer and LG mobile phone. The profiling approach is a method of choosing a particular strategy aligned with environmental factors. While various approaches have been used to check the fit between a business strategy and environmental factors, the literature on manufacturing strategy and logistics has commonly adopted the profiling approach. Major factors used in profiling variables are derived from the literature. Two samples, HP printer and LG mobile phone, are selected, because they represent major characteristics appropriate for each strategy. The profiling is based on data from semi-organized interviews with managers. Results - The profiling approach shows that the postponement strategy is a suitable one for HP printers. Most factors, such as product life cycle, large production volume, low-price, product value, and monetary density, support delaying end products until as late as possible. Despite some exceptions, such as delivery time and economy of scale, our analysis states that the overall profile of HP printer is favorable for the postponement strategy. On the other hand, LG mobile phone may adapt the speculation strategy. Although it has large production volume and low delivery frequency, most characteristics support the speculation strategy for this product. An interesting finding is that, despite common perception that advanced technology products such as mobile telephones favor the postponement strategy, profiling proposes the speculation strategy for this product. Conclusions - Our analysis shows that speculation is not the universal option for supply chain management, and that, when choosing a specific strategy, one should consider many factors simultaneously. A major implication of our work is to emphasize the role of environmental factors such as supply chain variables in choosing an inventory strategy, and the importance of fit rather than solely strategic orientation. A theoretical contribution is to demonstrate the benefit of the simultaneous consideration of business variables in choosing specific strategies. For practitioners, our work leads us to consider the existence and the potential of speculation as a counter-measure to postponement. In addition, the comprehensive framework in this research may be instantly used in examining a practical strategy.

  • The 21th century is rapidly turning to the era of supernational competition aimed at global customers. Under these circumstances, applying the value innovation to space which will be in charge of value creation is recognized as being essential to life. This study aims to newly define the conception, the viewpoint, and types on applying the value innovation to space, which has not been established logically yet. The purpose of analyzing cases where the innovation was applied at home and abroad is to provide basic logic to establish these concepts in real space design. This study is prospected to be the core strategy of growth cause for maintaining our industrial development, so it is suggested that accepting, widening, and developing it may enable us to prepare for the continued innovation to space.

  • The purpose of this study is to investigate the impact of selection attributes of dessert cafes on experience value and revisit intention. A survey was conducted from June 3, 2017 to the June 27th, 2017 with dessert cafe users. Out of 200 responses collected, a total of 157 responses was included for the data analysis. The results from this study are as follows. First, it was found that, the menu features of selective attributes of dessert cafes only affected experience value. However, healthy menu, price, and atmosphere of selective attributes of dessert cafes didn't impact on experience value. Second, experience value of dessert cafes significantly influenced revisit intention. As a result, managers of dessert cafes need to develop an effective marketing strategy to improve the customer experience value so that customers can revisit their dessert cafe and will also develop the unique menu.

  • The value of universities in driving economic development has been understood for a long time. However, with the increasing importance of the 'science-entrepreneurship' relationship in giving science its modern economic value there is growing interest in how this dynamic can be enhanced. One of the strategies that has been widely adopted has been the creation of research-science-technology parks although commonly these projects were being established prior to the theoretical approaches that justify their development. This paper reports on a study that measured the financial value of the links between the University of Surrey and tenants on its Surrey Research Park project and also looks forward at strategies being adopted by the University concerning the continuous improvement of its technology transfer offering to increase the value of these links and put some empirical data behind the claims of the value of research-science-technology parks as part of a wider innovation strategy.

  • The social and economical value assessment of railway facilities implies unaccountable values such as: reduction of travel time, reduction of car accident, reduction of air pollution. However, the value of railway facilities has been evaluated as the transportation and management results. The investment and management results of railway need to be considered objectively. Therefore, this study established the economical value assessment method of railway facilities composed of 10 items of economical value through the existing a preliminary assessment investigation, a manual of railway investment assessment, paper study. In addition, this study proposed the strategy for the value assessment of railway facilities before and after.
