In this paper an algorithm that represents shape sequences with moving frames parallel along the sequences are developed. According to Levi-Civita connection, it is not easy to measure the variation of the vector fields on non-Euclidean spaces without tools to parallel transport them. Thus, parallel transport of the vector fields along the shape sequences is implemented using the theories of principal frame bundle and analyzed via extensive simulation.

Receiving information and transmitting it is the most basic and important thing in numan society. And modern communication is not only transmitting objective information but also a visual communication which shows feeling of each emotions and image-motive. Introduction of Motion graphic which was grown by new media changed opening title sequence to a more expanded genre. The purpose of this research is to announce the new value of opening title sequence. Motion graphic will be used continually as an important way to communicate and also a guideline which could transmit exact informations and emotions to viewers with creative expressions.

In order to create a wind resource map, we need wind data, contour map and roughness map. Moving Filter technique was applied to Udo of Jeju Island to improve the accuracy and efficiency of creating roughness map based on the Land Cover Map of the Ministry of Environment. The Land Cover Map was simplified using moving filtering, and the roughness map was created with this Land Cover Map. The wind resource map was created using this roughness map. Finally, we verified the validity and application of moving filter technique for wind resource map. As a result, the wind map which was created using the roughness map with moving filtering showed bias values which were all negative. It means the wind map is underestimated to values of wind energy and RMSE values were also from 0.0237m/s to 0.0253m/s at 50m height. In other words, estimation of wind resource using image filtering provides reliable results at 80m height typically when the wind turbine is installed. Finally, we found that image filtering technique is very useful tool to make wind resource map.

A voice coil actuator with moving coil type for scanning mirror system of barcode reader has been developed. The actuator has a simple structure including a magnet, a coil and a pin. The performance of the actuator is analyzed by a linearized theoretical model. And the dynamic performance of the proposed actuator is predicted through motor constant and restoring constant obtained by finite element simulations. The theoretical model was verified by the prototype which has 64 Hz resonance frequency and 60 deg reflecting angle. We also discovered that that 3 V input can make the actuator rotate over 61.8 deg reflecting angle at 50 Hz resonance frequency. The proposed actuator can simplify its driving configuration because of its implementation of open-loop control.

In this paper, In this paper, we use two methods to compare the slim speakers. That way, the diaphragm scan using laser and diaphragm photographed using a thermal imaging camera. Slim speaker has the structure of a flat plate type. Break-up mode by this characteristic is displayed in a larger size. Further, since the installation space is narrow, it has limited moving coil cooling. As a result, the break-up mode slim speakers, a significant impact on quality. In this study, try to connect the break-up mode of the diaphragm, the heat transfer mode of the diaphragm. Experiment for comparison, a two-step. The first step is to measure the divided vibration through the vibration plate scan. The second step measures the diaphragm photographed using a thermal imaging camera. Then, compare the results of both of the same frequency. Thus, comparing the heat transfer pattern and the pattern of break-up mode. Tend to be analysis of break-up mode from the pattern comparison, and document for the optimum design.

The purpose of this study is optional cinemagraph ads based on the case through the psychological theory of visual multimedia story qualitative analysis, quantitative analysis. Cinemagraph analysis would like to present the model. The analysis popular advertising model who starred with the higher profile in 2016 Gmaket of cinemagraph series of ads research, literature research, and Internet media. Analysis, case studies, etc. The analysis appeared around 10 percent was the most effective in the form of moving the form of copper wire. Part of the video cinema than the overall movement of the graph bigger visual flow effects is a dynamic. Moving the direction of the model used copper wires and broadly consistent with the product. Subject & Surrounding and margins are being used within one point or two points. The story of probability model in the short and expressing simple action of the product. Direction of the action, the proportion of multimedia for quantitative analysis of space story for the qualitative analysis of the periphery and jujebu, stories, such as the probability of four.For consideration the terms.

This study analyzed the factors consisting moving poster design. In order to analyze the elements of moving poster, the researcher reorganized the elements of moving posters by referring to the previous studies on printed posters, motion graphics and works of moving posters. In this study, moving poster components were classified into 'communication', 'visual and form', and 'sound'. In 'communication' section, moving posters had narrative elements, including scenes, because of the time and movement added by the poster's original function. The 'visual and form' section was classified into graphics, layouts, movement, and time. Graphics refered to various graphic objects constituting the screen such as photo, illustration, typography, color, diagram. Layout means screen layout, size, and orientation of the screen. Movement section was divided into 'subject of movement' and 'attributes of movement'. Time was classified physical time such as playing time and subjective time felt by the audience. Also, the researcher categorized 'sound' as an additional section, since most moving posters did not include sound.

According to recent technological developments in high-power LEDs, the stage lighting is one of most important areas to apply power LED system. Moving light for color rendering of stage uses the RGBW(red, green, blue, white) color mixing method. LED moving light system needs to have a wide range of dimming control as enough to operate at very low power. Also LED dimming system should not be induced color-shift and flicker in camera. This paper is experimentally verified the LED Moving Light driving circuit of 200Watt level designed to satisfy the above characteristics which applied the DC current-controlled and PWM mixed dimming method.
