The point spread function (PSF) of an optical system is in general defined as a two-dimensional intensity distribution which results from a single point source at infinity. It is an important key for the evaluation of the optical performance of an astronomical telescope. The PSFs of the soft X-ray telescope (SXT) aboard Yohkoh were measured in a wide range of the field-of-view under the in-flight configuration at White Sands Missile Range prior to launching the satellite. It has been known that the SXT PSF has a sharp peak at the core and the intensity drops very fast as it goes distant from the center. Due to the combination of this sharp peak at the PSF core and the effect of undersampling by a large pixel size, a carefully designed method is requested in the examination of the PSF data. The pattern of the SXT PSF is determined by the fitting of a mathematical functional form to the pre-launch experimental data. The elliptical Moffat function has been adopted for the evaluation of the SXT PSF. It is revealed from our study that the SXT PSF shows a peculiar characteristics, and thus a careful consideration on the undersampling effect and also a proper choice of statistics are necessary for the determination of the best fit function of the PSF. Details on the on- and off-axis SXT PSF in the field-of-view will be introduced and discussed in our presentation.
The inspiration and its application in fashion design is considered as one of the important factors in boosting the fashion arena. Many inspirations are adapted in fashion de-sign and they make the fashion design unique and characteristic. In this study many fashion designs are analyzed to find what kind of inspirations were adapted and utilized for the fashion design in reality. The nature historic costumes ethcin costumes arts sciences literature music sports were revealed as the sources of fashion inspiration.l The concerns on the environments movies and dramas could provide inspirations in fashion as well. Several contents or steps were studied to provide the one of the example of appli-cations as follows: 1. The works of Marc Chagall were analized to figure out and several plastic characteristics from his works were revealed such as fantastic strong colors unreal animal pattern or their details his wife and friends various divisions of the surface and so on. These attributes had been favored in depiction of his works to ex-press his home town or nostalgia. 2. '90s fashion designs inspired by the works of Chagall were analized to find out the meth-odology or the process of designs. The same Chagall colors were used in design and similar pattern were expressed through beaded work or printing jobs. The surface designs such as printing were the most prefered method in adapting the inspirations. 3. The plastic characteristics of the work of Chagall were attempted in clothing design and construction. The color combination patterns which remind the animals the surface divisions were used in design ot practive the methodologies.
The ceremonies were roughly categorized into four: coming of age, marriage, funeral and ancestral worship. Among them, the funeral was a representative example to show ancestral worship. As it symbolizes the worship to ancestors, its procedure was complicated and formalized. It was undoubtedly certain that formalized mourning dresses and complicated table setting for sacrificial services to ancestors were burdens. Although what was symbolized by mourning dresses was different depending on the wearers purposes, it was thought that no clothing had such unusual symbolism as mourning dress. When the composition of mourning dress was examined, it was shown that Taoism, family relation of Confucianism or symbolic clothing system of Shamanism were combined. Mourning dress first represented the Confucian idea of ancestral worship. For the composition of clothing in which a shamanistic element was inherent, forms of birds were used to guide the dead soul to the other world. In cutting out mourning dress, opposite concepts of Yin and Yang, and closure and openness were used to show a harmony between heaven and the earth. Male and female were represented through sewing techniques. The period of observing the mourning period depended on the degree of kinship. The degree to which the clothing was loose indicated the degree of sadness and kinship. Load blocks and tear pads indicated the degree of sadness. In considering the above indicators, family relation and filial piety to ancestors had a great effect on the form and details of mourning dress. Shamanistic elements as well as Confucian ones were inherent in mourning dress, which resulted in the combination of Taoism and Confucianism.
Pop art, an artistic trend which was actively popular centering around popularization of America in the 1960's, appears as punk style in the 1970's and as one of diversified style in the 1980's, and have co-existed in the third culture and pluralistic combination since the 1990's. The image of pop art includes complexity, familiarity and popularity as well as extension of media, and so directly influences the fashion in the end of the 20th century. Especially, sportslook show up by the virtue of rising lower cultural area such as street fashion becoming influential and change in life style, which was recreated as clothes by developing characteristics of design including style, details and colors showed in active sports wear. This study is aimed to ana analyze the image of pop art showed again in the modern fashion in the end of the 20th century and graffiti-art which was well known to the general public after the 1980's. Through this analysis, I will study characteristics of pop art showed in sportslook which is the mainstream in modern fashion and graffiti of Keith Haring. Consequently, I suggested a functional, esthetic and future-oriented sports look design which comprises the image of the graffiti-art of Keith Haring by using Design CAD(photoshop & primavision) enabling to attempt variously and to derive quickly the output of design and textile.
This study considers aesthetic characteristics by examining red carpet dress in China film festival. The research methods were quantitative and qualitative analysis of red carpet dress images collected from 2015 to 2019 on websites according to four criteria following previous research on red carpet dresses. The results of the study are as follows. First, the analysis of red carpet dress silhouettes showed that A-line silhouettes, slim silhouettes, and mermaid silhouettes appeared. Second, in terms of colors, one color, black, represented a higher proportion of the dress colors than the combination of different colors. Third, soft texture occupied the highest proportion of material textures, and combinations of materials with different textures were also used. In the case of patterns, the proportion of dresses without patterns was high, and natural patterns were found in the largest proportion. Beads and sequins accounted for most of the dress details, and the analysis showed that various detail types such as embroidery, slits, ruffles, and belts were used in the red carpet dresses. The aesthetic characteristics of the red carpet dresses worn at the China film festival were analyzed as sensual, elegant, decorative, and simple.
Given the small bit allocation for motion information in very low bit-rate coding, motion estimation using the block matching algorithm(BMA) fails to maintain an acceptable level of prediction errors. The reson is that the motion model, or spatial transformation, assumed in block matching cannot approximate the motion in the real world precisely with a small number of parameters. In order to overcome the drawback of the conventional block matching algorithm, several triangle-based methods which utilize triangular patches insead of blocks have been proposed. To estimate the motions of image sequences, these methods usually have been based on the combination of optical flow equation, affine transform, and iteration. But the compuataional cost of these methods is expensive. This paper presents a fast motion estimation algorithm using a multiple linear regression model to solve the defects of the BMA and the triange-based methods. After describing the basic 2-D triangle-based method, the details of the proposed multiple linear regression model are presented along with the motion estimation results from one standard video sequence, representative of MPEG-4 class A data. The simulationresuls show that in the proposed method, the average PSNR is improved about 1.24 dB in comparison with the BMA method, and the computational cost is reduced about 25% in comparison with the 2-D triangle-based method.
The Advanced Test Reactor (ATR), at the Idaho National Laboratory (INL), is one of the world's premier test reactors for providing the capability for studying the effects of intense neutron and gamma radiation on reactor materials and fuels. The physical configuration of the ATR, a 4-leaf clover shape, allows the reactor to be operated at different power levels in the comer 'lobes' to allow for different testing conditions for multiple simultaneous experiments. The combination of high flux (maximum thermal neutron fluxes of 1E15 neutrons per square centimeter per second and maximum fast [E>1.0 MeV] neutron fluxes of 5E14 neutrons per square centimeter per second) and large test volumes (up to 122 cm long and 12.7 cm diameter) provide unique testing opportunities. The current experiments in the ATR are for a variety of test sponsors - US government, foreign governments, private researchers, and commercial companies needing neutron irradiation services. There are three basic types of test configurations in the ATR. The simplest configuration is the sealed static capsule, which places the capsule in direct contact with the primary coolant. The next level of experiment complexity is an instrumented lead experiment, which allows for active control of experiment conditions during the irradiation. The most complex experiment is the pressurized water loop, in which the test sample can be subjected to the exact environment of a pressurized water reactor. For future research, some ATR modifications and enhancements are currently planned. This paper provides more details on some of the ATR capabilities, key design features, experiments, and future plans.
The images signifying flight in modern costumes are not made of one characteristic but the combination of complex meanings. Among the distinctive features some of them are as follows. First, the flying styles found in the costumes showed the birds as agents which sent human spirit to the celestial body. By simplifying the images of the wings connecting the present age with the heavenly body, the transforming emotions towards rhythm, direction, and organic curves transcending the real objectively constitutes a new space for expression. Second, colors appeal directly to man's emotions and incites emotional responses. The flying was shown in lines and colors. By using horizontal , vertical, oblique, and spiral lines and contrasted and paralleled colors, man's desire to fly dwells in newly colored space by reflecting speculative emotion through uniting surface. Third, the flying except for the costumes can be found in the advertisement through model's pose and camera technique, the flying itself is described through model's pose, the materials of the costumes, details, and sustaining stuffs. This symbolizes man's wish towards the unknown world vividly and dynamically. As discussed above the spirit of flying was, when expressed distinctively , in accordance with the varying cultural traits and transitions. The shape made by the vitality of symbolizing flying birds and animals along with the flying in the natural aspects such as wind and cloud were reappeared, simplified and symbolized , in modern costumes as consituting a new modeling space.
This investigated the romanticism of Alessandro Michele who leads new trends in fashion industry as a creative director for Gucci. In this study, 307 women's wears exhibited by Alessandro Michele for 3 years in Milan collections from 2015 F/W to 2017 F/W are categorized according to the aesthetic characteristics of romanticism. Additionally, the five aesthetic features of Gucci's fashion design are an addition since the appearance of abnormally large size under the influence of postmodernism. The results based on the study purpose are as follows. First, the decoration makes the garments stand out by using fancy materials, splendid multicolor combination, applique embroidery and three-dimensional objects. Second, exotic style is expressed from an occidental perspective using Chinese traditional fashion or textiles, and exotic accessories. Thirdly, sensuality is manifested using see-through materials to emphasize women's breasts, or the beautiful and sexual expression of women's body. Fourth, the new creations are designed by combining contrasting elements, such as disparate materials and, different genders. Furthermore, traditional cultures like baroque and rococo, and the 1970's vintage looks inspires the creation of retro-style. Finally, the appearance of extremely large shoulders, silhouettes, and details of the human body can be explained with expansive tendency. The aforementioned results further suggest that diverse characteristics are expressed via reflection of contemporary art and trends.
Column base connections are critical components in steel structures because they transfer axial forces, shear forces and moments to the foundation. Exposed column bases are quite commonly used in low- to medium-rise buildings. To investigate shear transfer in exposed column base plates, four large scale specimens were subjected to a combination of axial load (compression or tension) and lateral shear deformations. The main parameters examined experimentally include the number of anchor rod, arrangement of anchor rod, type of lateral loading, and axial force ratio. It is observed that the shear resisting mechanism of exposed column base changed as the axial force changed. When the axial force is in compression, the resisting mechanism is rotation type, and the shear force will be resisted by friction force between base plate and mortar layer. The specimens could sustain inelastic deformation with minimal strength deterioration up to column rotation angle of 3%. The moment resistance and energy dissipation will be increased as the number of anchor rods increased. Moreover, moment resistance could be further increased if the anchor rods were arranged in details. When the axial force is in tension, the resisting mechanism is slip type, and the shear force will be resisted by the anchor rods. And the shear resistance was reduced significantly when the axial force was changed from compression to tension. The test results indicated that the current design approach could estimate the moment resistance within reasonable acceptance, but overestimate the shear resistance of exposed column base.
