In Ubiquitous era. architecture is not the old building adapting ubiquitous technology. In order to take the role as new architectural paradigm in space, environment and technology, it has to develop technology continuously and experimental architecture at the same time. it must have co-evolution of architectural field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion and user-centric human-friendly. It will be the new paradigm of Ubiquitous digital space. Digital technology resulted in a change to a society as well as to the life of human and its way of thinking. Due to those changes, new terms or concepts come out and a new meaning is added to the conventional concepts. This aims to examine type of spatial contexts for interaction design experience. This study is performed through Literature research for theory by interactive space and case studies for construction elements to design. The range of case study is limited to interaction space in addition of interactive elements and user interface. And analysis conclusion is show the many type, First, Interactive space has special purpose for make a interaction by intelligent elements.(sensor, program, algorithm, New-technology) Second, Interactive space was cooperation with various professional for space purpose. Third. Interactive space is self-develop by algorithm, program, sensor network and that is harmonize with user. finally. Interaction space is show the temper elements about allness, metastatic, activeness, liquidity, relationship. That was written by ecological theory.

This paper attempts to the couple formation of date show program SBS as a hybrid genre. The characteristic of hybrid program emergent popular formation of television culture in our society, as well as encountered by audiences. It also implies that the visual culture transforms the popular elements of episode of television culture as a reality show program refer to central field of media industries. One final thing that date show program has been rapidly changed in terms of many different methods of format, as well as continued process of the date show program is an opportunity to raise the daily lives of fueling.

Blushes are known to generate unwanted nano particles of dust and harm elements in various electro-mechanical home appliances. Subsequently, the blushless type is proposed as an eco-friendly alternative to replace the brushes. Further, the expensive magnetized rotor of the Blush-less DC (BLDC) is to be replaced in SRM, which requires complex control not to overflow the switching current the system within a budget. This paper introduces an approach to implement an efficient yet, cost-effective controller for high-speed rotation control, employing Switched Reluctance Motor (SRM) BLDC motor.

The purpose of this paper is concerned with a development of air gun for use at work. A air gun is the tool to remove of cutting fluid and workpiece chip in industrial field used machine tool. And it generally is used to shoot a jet of compressed air. Worker must prepare respectively air gun for suction and shooting a jet of compressed air. Therefore we has developed new air gun. In this paper we research for design and analysis of it. The air gun is composed of body, pipe, opening and shutting unit, turning unit, air tube and elements for fabrication. The developed air gun is experimented to confirm the efficiency.

The objective of this study is to identify the individual characteristics and the elements of social capital hence a suitable design of social capital reinforcement can be proposed to promote a sustainable community-based mangrove management. The research conducted in three villages that were selected based on mangrove ecological differences in Lampung Province, Indonesia. Qualitative data was collected through field observation and in-depth interviews with key informants. The results showed that the population in the three villages dominated on productive ages, worked as farmers, and less educated (only a half of the population had fulfilled the basic education standard of Indonesia). The study results also indicated that the social capital in the communities showed minimum condition of interpersonal attachment and cooperation. This condition was derived from the attitude of the people who only took personal benefit without concerning to others' welfare. Many programs conducted by government to ensure the conservation of mangroves were project-oriented with minor participation of community. The minor participation might also contributed to the minimum of social capital in the community. To improve social capital, the communities should strengthen mutual trust based on mutual benefit to increase members' participation in mangrove activity.

Large displacement and rigidity about rubber component are expected by nonlinear and large deformation analysis in this study. Rubber is also used by the model of Mooney-Rivlin and the self contact between rubbers is established. There is the friction between rigid body and rubber, wall and floor. The nonlinear simulation analysis used in this study is expected to be widely applied in design, analysis and development of several rubber components which are used in automotive, railroad, and mechanical elements etc. By utilizing this method, time and cost can also be saved in developing new rubber product. The analysis of rubber components requires special material modeling and non-linear finite element analysis tools that are quite different from those used for metallic parts. The objective of this study is to analyze the rubber component with large deformation and non-linear properties.

Due to the modem MEMS technologies, the electron lenses that are used in the microcolumn can have much smaller optical aberrations compared with conventional electron lenses for the bulky electron columns. Since the electron lens system have great effect on the performance of the microcolumn, it is important to study the dependence of image quality on the configuration of the electronic imaging system, among which the source-lens part is most sensitive. In this work, we investigated the electron beam characteristics according to the shapes of extractor and limiting aperture that are elements of the source-lens part. By analyzing the data obtained, we proposed the optimum configuration of the electron lens system.

The city such as Tokyo is an instance of maximizing the urban character that is different from other cities by actively utilizing color-scape among elements making identities. On this study, It's focused on Tokyo, developing urban identities, and aim to consider the implication and the feature of urban landscape formation by looking for the background of business and future images of the urban regeneration planning, aims, processes, policies, the color-scape about the landscape formation planning. It's expected to be reference for development of urban regeneration and landscape plan in a long-range view.

A rivet which can fasten two parts is one of an important mechanical elements. In this study, the process design of a blind revet is implemented using finite element method in order to manufacture it which can resist high vibration and has strong coherence between two parts. Considering plastic flow, ease of manufacture, high strength, material loss, and so forth, an optimal four-stage process is proposed by finite element analysis and process design rules. In addition, the finite element simulation results such as shape of the forged rivet, strain distribution and forging load are investigated for the usefulness of the forging process of the blind rivet. These results will be contributed to the forging process design and the die design of the blind rivet.

This paper presents the analytical-FE (finite element) squeal model, which can provide the efficient simulation time and accuracy. The system geometry and the extraction of the vibration modes were constructed using the finite element method. Instead, the friction contact model was derived from theoretical contact kinematics of the rotating disc and the stationary pads. This modeling procedure was incorporated into the perturbed equations of motion based on the finite elements of the system. Throughout the analytical-FE squeal model, the accuracy of linear stability analysis and the simulation time of FE squeal analysis were improved. In addition, the sensitivity of contact stiffness on brake squeal and the mode-coupling mechanism were provided by the system parameter study.
