Strengthening slender reinforced concrete (RC) columns is a challenge. They are susceptible to overall buckling that induces bending moment and axial compression. This study presents the precise three-dimensional finite element modeling of slender RC columns strengthened with fiber-reinforced polymer (FRP) composites sheets with various patterns under concentric or eccentric compression. The slenderness ratio λ (height/width ratio) of the studied columns ranged from 15 to 35. First, to determine the optimal modeling procedure, nine alternative nonlinear finite element models were presented to simulate the experimental behavior of seven FRP-strengthened slender RC columns under eccentric compression. The models simulated concrete behavior under compression and tension, FRP laminate sheets with different fiber orientations, crack propagation, FRP-concrete interface, and eccentric compression. Then, the validated modeling procedure was applied to simulate 58 FRP-strengthened slender RC columns under compression with minor eccentricity to represent the inevitable geometric imperfections. The simulated columns showed two cross sections (square and rectangular), variable λ values (15, 22, and 35), and four strengthening patterns for FRP sheet layers (hoop H, longitudinal L, partial longitudinal L_w, and longitudinal coupled with hoop LH). For λ=15-22, pattern L showed the highest strengthening effectiveness, pattern L_w showed brittle failure, steel reinforcement bars exhibited compressive yielding, ties exhibited tensile yielding, and concrete failed under compression. For λ>22, pattern L_w outperformed pattern L in terms of the strengthening effectiveness relative to equivalent weight of FRP layers, steel reinforcement bars exhibited crossover tensile strain, and concrete failed under tension. Patterns H and LH (compared with pattern L) showed minor strengthening effectiveness.

The purpose of this study is to propose a modern use of traditional culture by developing creative fashion designs that combine modern and traditional styles based on an analysis of traditional costumes of women in the Tang Dynasty of China. The characteristics of the Tang Dynasty women's costume are as follows. The Tang Dynasty women's costume consists of a short coat (衫, Shan), skirt (裙, Qun), half-arm shawl (半臂, Banbi), and short embroidered cape (帔, Pei). The colors are succinct and elegant, commonly red, yellow, green and navy blue in its entirety. It may be classified by pattern that blend plant patterns, animal patterns, geometric patterns, and two or more mixed patterns. On the basis of the characteristics for traditional women's costume during the Tang Dynasty, the CLO 3D program is employed to develop digital fashion design for four pairs of 3D digital clothing and the production of two pairs of work product. The results are as follows. First, the development of fashion design reflecting the design characteristics of traditional women's clothing in the Tang Dynasty of China could be expressed as fashion design reflecting unique values while connecting tradition and modernity. Second, the 3D virtual clothing program displays an extremely important effect in design deployment and pattern arrangement by having efficiency and convenience in clothing production. The CLO 3D program is closely combined with the 2D design and 3D effect and heightened efficiency while being appropriate to realize sustainability while saving processing time and energy for the sample products. Third, the production of an actual product by facilitating the 3D virtual clothing design may lead to time savings and an effective economy and may allow for the comparison of digital fashion design and actual products as well as confirming the effects of digital fashion design.

Sonia Delaunay(1885$\~$1979) was one of great pioneers of abstract art, who looked at clothes and fabrics with a plastics eyes. In Association with her husband Robert Delaunay, they were instrumental in founding the movement of Orphism, she proceeded to mix strong and bright colors into her art and had a brilliant influence on the decoration and women's fashion of the 1920's. Having a strong sense for dramatic and decorative color derived in part from childhood remembrances of Russian folk art she initiated a total revolution in which she created her first simultaneous dress with multi-colored samples of materials. She extended the principle of color's simultaneity to the field of fashion, fabric design and applied art. She was interested in the dress for ballet and opera. Fashion designer Paul Poiret asked her to design the fabrics and she created the geometric and abstract patterns with her strong color. It seemed that her design was revolutionary and avant-garde. Always she desired not only art of seeing but also art of living. The purpose of this study is to recognize the influence she had upon the history of modern fashion and fabric design. It was remarked that her paintings served as a basis for later developments in Kinetics Art and had influences on 1980' s abstract patterns for silk dress. Finally, the concept 'simultaneity' of her art signifies endless rhythmes in space and time.

This paper analyses Wassily Kandinsky's abstract paintings. this paper aims to discuss phases of Kandinsky's works as well as their formative characteristic theory. Practically, with formative characteristics in Kandinsky's paintings such as point, line, plane, form and color, this paper presents four sets of costumes. Among which, geometric patterns are intensively collaged as the formative characteristic of "point" calls for; crossed necklines and waistlines are applied as the characteristic of "lines" represents; plane and solid patterns are adopted as the main parts and ornaments as both the characteristic of "plane" and that of "form" claim; three primary colors - red, blue and yellow - are introduced as the characteristic of "color" depicts. Artificial leathers are used as the main fabric, patchwork and draping as so in technology. Therefore, with the theoretical and practical efforts, this paper aims to seek the interdisciplinary possibilities between paintings and fashion arts, and in order to develop several fashion designs representing modern aesthetics with their unique characteristics.

The Belgian textile wallcovering has the following background. The unique oceanic climate is optimized for flax. Beginning in the thirteenth century, British wool was produced for export to Britain or neighboring countries. Since the 15th century, Flemish paintings were influenced by color implementations, and these colors have influenced the developments of tapestry and art. Since that time, tapestry and paintings combined with paper technologies and Oriental civilizations, such as silk, that had been developed through trade ports, have been transformed into the form of current wallcoverings. Belgium produces the highest quality textile wallcovering using natural materials i.e., a combination of irregular and modern materials, and the implementation of different colors. The Belgian textile wallcovering is also a good representation of nature at the Heimtextil 2018, It provides a wide range of colors while retaining the best styles for wallcoverings in Belgium. The characteristics of Belgian wall coverings are: First, the high proportion of achromatic colors, especially the white ones, are analyzed for current trends. Second, it expresses the characteristics of materials by using only one material. This not only shows a high level of understanding of natural materials, but also shows a high level of development in terms of processing technology. Thirdly, linen was made into a formative expression using wrinkle processing and by printing geometric patterns, the rough texture of natural materials was expressed in harmony with modern patterns.

Face detection is a crucial part of the face recognition system. It determines the performance of the whole recognition system. Hausdorff distance metric has been used in face detection and recognition with good results. It defines the distance metric based only on the geometric similarity between two sets or points. However, not only the geometry but also the local patterns around the points are available in most cases. In this paper a new Hausdorff distance measure is proposed that makes hybrid use of the similarity of the geometry and the local patterns around the points. Several experiments shows that the new method outperforms the conventional method.

Numerical and experimental studies are presented for turbulent flows and heat transfer in annular channel with circumferential fins on the inner tube in a double pipe heat exchanger. Flow and heat transfer characteristics are periodically fully developed, and complex flow patterns are shown. Numerical calculations are executed by using modified TEACH-2E computer program based on the standard k-.epsilon. turbulence model. Mean velocity, turbulent kinetic energy, and Reynolds stress distributions are measured with the hot wire anemometer. Static pressures on the outer wall of the pipe are measured for three pitch-height ratios and several Reynolds numbers. Numerical predictions generally show reasonable results in comparison with experimental results. When the pitch-height ratio is about 5.0 and other geometric parameters are fixed in this paper, maximum heat transfer is achieved. Reattaching flow patterns appeared in this region. As the pitch between fins is increased beyond 5.0, mean Nusselt numbers are decreased and the pressure drop through one pitch almost remains.

This paper proposes a 3-D pose (positions and orientations) estimation system based on the recognition of circular ring patterns. To deal with monocular vision-based pose estimation problem, we specially design a circular ring pattern that has a simplicity merit in view of object recognition. A pose estimation procedure is described in detail, which utilizes the geometric transformation of a circular ring pattern in 2-D perspective projection space. The proposed method is evaluated through the analysis of accuracy and precision with respect to 3-D pose estimation of a quadrotor-type vehicle in 3-D space.
