  • A force reflecting hand controller can be used to provide more realistic information to the operator of a teleoperation system such as kinesthetic feedback from a slave robot. In this paper, a new design concept of a force reflecting 6-DOF hand controller utilizing the kinematic structure of a Stewart Platform is presented. Based on the optimal design technique of a Stewart Platform, a force reflecting hand controller has been designed and constructed to verify the technical feasibility of proposed design concept. In order to provide an operator with kinesthetic feedback information, a force mapping algorithm based on a reciprocal product of screws has been introduced. Finally, the technical feasibility of the design concept has been demonstrated through some of experimental results of the device under virtual environment on a real-time graphic system.

  • In this paper, an optimal design technique for a Stewart platform has been presented considering workspace and dexterity. In the definition of a design objective function, previously suggested dexterity index was used to be maximized. In this optimal design process, the workspace can be used as design constraint when necessary. An algorithm for workspace computation has been briefly described. Finally, optimal desigm results for some example cases have been presented.

  • In this paper, we propose an automatic generation method of transaction level(TL) model from algorithmic model to verify system specification fast and effectively using virtual platform. The TL virtual platform including structural properties such as timing, synchronization and real-time is one of the effective verification frameworks. However, whenever change system specification or HW/SW mapping, we must rebuild virtual platform and additional design/verification time is required. And the manual description is very time-consuming and error-prone process. To solve these problems, we build TL library which consists of basic components of virtual platform such as CPU, memory, timer. We developed a set of design/verification tools in order to generate a virtual platform automatically. Our tools generate a virtual platform which consists of embedded real-time operating system (RTOS) and hardware components from an algorithmic modeling. And for communication between HW and SW, memory map and device drivers are generated. The effectiveness of our proposed framework has been successfully verified with a Joint Photographic Expert Group (JPEG) and H.264 algorithm. We claim that our approach enables us to generate an application specific virtual platform $100x{\tims}1000x$ faster than manual designs. Also, we can refine an initial platform incrementally to find a better HW/SW mapping. Furthermore, application software can be concurrently designed and optimized as well as RTOS by the generated virtual platform

  • The purpose of present study is to find design parameters and operating conditions of the HVAC system in a subway platform. The simulation was carried out for the flow, heat and mass transfer for heating, ventilating and air-conditioning(HVAC) environments in the subway platform. The steady-state. incompressible flow assumption and standard $k-{\varepsilon}$ turbulence model are adopted. The location of HVAC air inlet above platform and the volume flow rate of curtain air released from inlet B are chosen as main parameters in this study. The results of present study are following: In the case of existence of train, the heat and contaminant released under the train have no effect on the average temperature and mass fraction of contaminant in the platform, but heat released on the train has influence on the average temperature in the platform. Train acts as an obstacle to exhaust the contaminant in the platform, but has good effect on the average temperature in the platform.

  • Diverse operating systems and developed platforms of mobile devices are implemented by vendors exist. The software has to be developed by respective environment in designing the user interface of software. For the solution of the inconvenience, this paper proposes an integrated platform 4A DUOS for developing user interface independently. The proposed platform can use web language not dependent on various operating systems, and offer online access to API and component templates to provide the convenience of the user interface design. Also, the server with on board designed user interface implements the service to the user. Therefore, the users can design the independent user interface on various mobile devices by using only one source.

  • The purpose of this paper is to design a platform that is easier for users to provide membership services to consumers in systems used for non-face-to-face orders such as interphones and kiosks than conventional systems. In the past, memberships used cards, smartphones, and personal information to create barcodes, but consumers have difficulty managing memberships that exist in each company, and as unmanned ordering stores through kiosks and interphones increase, more and more consumers do not accumulate membership services. In order to increase the usability of membership services, an integrated platform design for the utilization of membership services is proposed. The purpose is to integrate and provide each membership service history with one view, and to provide consumers with a platform to integrate and check multiple services into one.

  • The objective of this research is to development of a parametric design system for membrane structures. The parametric design platform for the spatial structures has been designed and implemented. Rhino3D is used as a 3D graphic kernel and Grasshopper is introduced as a parametric modeling engine. Modeling components such as structural members, loading conditions, and support conditions are developed for structural modeling of the spatial structures. The interface module with commercial structural analysis programs is implemented. An iterative generation algorithm for design alternatives is a part of the design platform. This paper also proposes a design approach for the parametric design of Spoke Wheel membrane structures. A parametric modeling component is designed and implemented. SOFiSTik is examined to interact with the design platform as the structural analysis module. The application of the developed interface is to design optimally Spoke Wheel Shaped Ductile Membrane Structure using parametric design. It is possible to obtain objective shape by controlling the parameter using a parametric modeling designed for shape finding of spoke wheel shaped ductile membrane structure. Recently, looking at the present Construction Trends, It has increased the demand of the large spatial structure. But, It requires a lot of time for Modeling design and the Structural analysis. Finally an optimization process for membrane structures is proposed.

  • This study started with the question "Shall we apply the existing record management method to our trivial daily records?" For the general public, we focus on media that thinks more about daily recordings and suggests a better method, suggesting a 'social platform' as a plan, and using the user's visual approach through UX design methodology. The social archive proposed in this study aims to be a 'square' where various people can gather and communicate and share. A space that can record daily life using 'record' as a basic body Purpose It aims to provide the basis for basic research in various fields, and aims to function as a space for communication of various research things such as researchers and researchers, researchers and producers. In order to maintain, focus on the prerequisites of the existing construction, the items to be researched when constructing the daily archive are 'creative methodology to change research items when building a paradigm', 'network with related organizations', 'service plans for persistence', and characteristics of social media. We discussed the possibility of social media as a social archive platform. Finally, while looking at the user experience design process, I designed some features of the social archive and suggested things to do in UX design.
