The purpose of this study was to analyzed the types of Deformation dipicted on the late 1990s western costumes. The late 20th century cultural experience or lifestyle is interpreted with 'popular culture' ,popular culture is described as cultural phenomenon in postmodern condition. Contemporary popular culture may no longer be strictly 'working-class' as the idealistic purists of political formalism would like to , but does emerge from subordinate cultures, from the inventive edges of the consensus, and from the previously ignored and suppressed. It gestured through a widening democratization of styles, sounds and images, to an important remarking , to new possibilities , new perpectives, new projects. The growing importance of popular culture as a source for change of expression in the art, expecially new desire and will of artists has been caused lots of ' Deformation' in their works. Deformation, doesn't mean to represent object faithfully as it were seen through the artist's eyes. In a sense it implies that artists deform it with conscious or unconscious form. So in this study , the phenomenon of the postmodern western costumes is to describe ' formative language' called 'Deformation.' and it is classified three types, that is, 'Deformation of human-body image.' , Deformation of silhouette.' 'Deformation of detail.'. First , Deformation of human-body image is represented by deconstructive , subversive image in western costumes, a lot of costumes types of deconstruction have been shown by fashion designers are emphasized empathy with Deformation of human-body image. Second, Deformation of silhouette is also represented subversion of traditional manner and ultiity, underwear and outwear structure and ugly image. parody image of postumodernism , and so on. Above all, the late 1990s western costumes with Deformation of silhouette was an infinitely larger and more complex world than it appeared from outside and has expressed as a rejection against the values which traditional aesthetic concept had pursued, And parody through the change of internal meaning is to bring about parodox, irony, contempt, satire , unexpectedness by applying the original to inapproporate subject through its substition, inversion. Third, Deformation of detail is represented overdecoration, exaggerative distortion of for , overlapping and fetish image, parody image, kitsch image, and so on , Once fetish achieve a certain' style factor' among trendsettler, they are picked up by internationally famous fashion designers, The characteristics of kitsch are overdecoration , unfitness , imitation , used western costumes.

Polydimethylsiloxane (PDMS) is used as a scaffold for cell culture. Because both the stress and strain acting on the substrate and the hemodynamic environment are important for studying mechano-transduction of cellular function, the traction force of the surface of a substrate has been measured using fluorescence images of particle distribution. In this study, deformation of the cross-sectional plane of a PDMS block was measured by correlating particle image distributions to validate the particle image strain measurement technique. Deformation was induced by a cone indentor and a shearing parallel plate. Measured deformations from particle image distributions were in agreement with the results of a computational structure analysis using the finite-element method. This study demonstrates that the particle image correlation method facilitates measurement of deformation of a polymer scaffold in the cross-sectional plane.

수압 환경에서 사용되는 장비들의 내압성능을 시험평가하기 위한 하나의 방법으로 정수압을 인공적으로 조성하는 고압챔버 시험설비가 사용된다. 압력에 따른 시험체의 미세한 변형도 측정에는 스트레인 게이지가 적당하지만, 게이지의 측정 범위를 벗어난 대변형 값을 측정하기에는 적합하지 않다. 본 연구에서는 이러한 문제점을 해결하기 위한 방안으로 내압시험 중 수중카메라로부터 획득한 시험체의 영상정보를 처리하여, 수 mm 이상의 변형도를 추정할 수 있는 방법을 제안하였다. 제안된 방법은 카메라 영상을 2차원 영상처리하여 특징점을 찾고, 이 특징점의 움직임을 추적하여, 시험체의 변형도를 추정하는 방법이다. 이 방법을 이용하여 시험체 변형도를 추정하고 이를 실제 변형도와 비교 분석하는 연구과정을 통해 수 mm 이상의 변형도를 측정할 수 있는 방법으로 사용할 수 있음을 확인하였다.

The automated gate operating system is developed in this paper that controls the information of container at gate in the ACT. This system can be divided into three parts and consists of container identifier recognition car plate recognition container deformation perception. We linked each system and organized efficient gate operating system. To recognize container identifier the preprocess using LSPRD(Line Scan Proper Region Detection)is performed and the identifier is recognized by using neural network MBP When car plate is recognized only car image is extracted by using color information of car and hough transform. In the port of container deformation perception firstly background is removed by using moving window. Secondly edge is detected from the image removed characters on the surface of container deformation perception firstly background is removed by using moving window. Secondly edge is detected from the image removed characters on the surface of container. Thirdly edge is fitted into line segment so that container deformation is perceived. As a results of the experiment with this algorithm superior rate of identifier recognition is shown and the car plate recognition system and container deformation perception that are applied in real-time are developed.

Various 2D Shape deformation techniques has been presented recently. Concerning intuitive control of deformation, gradient domain 2D deformation techniques have an advantage over FFD(Free-form deformation) approaches, since they can deform objects with less control points. However, semantic shape properties such as thickness or length are difficult to handle in these approaches due to they treat the whole shape as a simple flat shape without structural meaning. In this paper, we propose a 2D shape deformation algorithm that deforms shapes using thin, deformable skeletal structure called freeform deformation axis (FDA). This concept separates the target shape and the deformable structure and thus enables user to manipulate shapes more intuitively.

In this paper, a deformation measurement technology for nuclear fuel rods is proposed. The deformation measurement system includes a high-definition CMOS image sensor, a lens, a semiconductor laser line beam marker, and optical and mechanical accessories. The basic idea of the proposed deformation measurement system is to illuminate the outer surface of a fuel rod with a collimated laser line beam at an angle of 45 degrees or higher. For this method, it is assumed that a nuclear fuel rod and the optical axis of the image sensor for observing the rod are vertically composed. The relative motion of the fuel rod in the horizontal direction causes the illuminated laser line beam to move vertically along the surface of the fuel rod. The resulting change of the laser line beam position on the surface of the fuel rod is imaged as a parabolic beam in the high-definition CMOS image sensor. An ellipse model is then extracted from the parabolic beam pattern. The center coordinates of the ellipse model are taken as the feature of the deformed fuel rod. The vertical offset of the feature point of the nuclear fuel rod is derived based on the displacement of the offset in the horizontal direction. Based on the experimental results for a nuclear fuel rod sample with a formation of surface crud, an inspection resolution of 50 ${\mu}m$ is achieved using the proposed method. In terms of the degree of precision, this inspection resolution is an improvement of more than 300% from a 150 ${\mu}m$ resolution, which is the conventional measurement criteria required for the deformation of neutron irradiated fuel rods.

The centrifuge model test is usually used for two-dimensional deformation and instability study of the soil slopes. As a typical loose slope, the municipal solid waste (MSW) landfill is easy to slide with large deformation, under high water levels or large earthquakes. A series of centrifuge model tests of landfill slide induced by rising water level and earthquake were carried out. The particle image velocimetry (PIV), laser displacement transducer (LDT) and marker tracer (MT) methods were used to measure the deformation of the landfill under different centrifugal accelerations, water levels and earthquake magnitudes. The PIV method realized the observation of continuous deformation of the landfill model, and its results were consistent with those by LDT, which had higher precision than the MT method. The deformation of the landfill was mainly vertically downward and increased linearly with the rising centrifugal acceleration. When the water level rose, the horizontal deformation of the landfill developed gradually due to the seepage, and a global slide surface formed when the critical water level was reached. The seismic deformation of the landfill was mainly vertical at a low water level, but significant horizontal deformation occurred under a high water level. The results of the tests and analyses verified the applicability of PIV in the two-dimensional deformation measurement in the centrifuge model tests of the MSW landfill, and provide an important basis for revealing the instability mechanism of landfills under extreme hydraulic and seismic conditions.
