The robot mainpulator for inspection of pressurizer in the nuclear power plant has been developed, which consists of four parts : 2 arms, movable gripper, base frame, contorl console. To extract the damaged electric heating rod inside pressurizer, the gripper has been developed using wire lope and self-locking mechanism. for the examination of the structural stability of the robot manipulator, stress analysis is performed by using the ANSYS code.

This paper has been studied a method that effectively displaying color image to monochromatic display such as PDA and movable-phone. Generally, the Floyd-Steinberg dithering algorithm has been used in this area and its' effectiveness were well known. But it shows some ugly patterns in white area and also shows some directionality in vertical and horizontal directions. To reduce those directionality, I suggest the error diffusion direction to be rotated randomly according to the bit value of the current position. This can also mitigate some ugly pattern in white area

Complex permittivities of reference liquids were measured by a liquid holder of slotted coaxial line with a movable probe at mobile communication frequencies. The validity of the liquid measurement system was checked by experimental tests with the reference liquids proposed in IEEE Std. 1528-200X or IEC 106/61/CDV.

Ocean seabed is usually covered with various types of marine soils. A marine soil is a mixture of two phases: soil particles that forms an interlocking skeletal frame, pore fluids that occupy a major portion of pore space. When gravity water waves propagate over a porous movable seabed, a hydrodynamic pressure on the fluid-seabed interface and fluid flow in the porous medium are induced. (omitted)

This study attempts to prove a superiority of slide-cover lighting. In order to solve these problems, cover materials with slide-type, blind cover should be prepared to make it easy to replace the light bulbs in a short time and to introduce a sense of decorative taste. Depending on an user's linking, slide-type cover can always change the indoor atmosphere by adjusting the light emitted from the lighting and meeting with the blind unit

In this paper, we propose a method that acquires proper image for barcode reading on camera-based barcode reading system. In the camera system, there is serious blurring problem, and to get proper output of the barcode, it must be solved. To solve it, we proposed two methods. The first one is to make the camera movable, so it can change the distance of focus. The other is software approach, and threshold value is revised through regression analysis. Using such process, we can notice that blurring problem can be overcome.

In [1], they build two populations' cellular automata model with predation based on the Penna model. In this paper, uncertain aspects and problems of imprecise and vague data are considered in this model. A fuzzy cellular automata model containing movable wolves and sheep has been built. The results show that the fuzzy cellular automata can simulate the classical CA model and can deal with imprecise and vague data.

Complex permittivities of human head simulating liquids were measured by a sample holder of terminated slotted coaxial line with a movable probe at mobile communication frequencies. The validity of the liquid measurement system was checked by experiments with the reference liquids. Liquids of ingredients for human brain suggested in IEEE draft and those made by the authors were measured by this slotted line system.

In this paper, crashworthiness of the KHST carbodies is evaluated by numerical simulation under the SNCF accident scenario (collision against a movable rigid mass of 15 ton at 110 kph) and the scenario of train-to-train collision at 30 kph. The numerical results of the several simulations, such as the accident collided against a deformable dump truck of 15 tons at 110 kph, the driver's dummy analysis using the integrated analysis method, and the accident of train-to-train collision for the first three units at 30 kph, show good performances in the viewpoint of energy absorption and survival space.
