Some characters and construction theorems of Pseudo Jacket Matrix which is generalized from Jacket Matrix introduced by Jacket Matrices: Construction and Its Application for Fast Cooperative Wireless signal Processing[27] was announced. In this paper, we proposed some examples of Pseudo inverse Jacket matrix, such as $2{\times}4$, $3{\times}6$ non-square matrix for the MIMO channel. Furthermore we derived MIMO singular value decomposition (SVD) pseudo inverse channel and developed application to utilize SVD based on channel estimation of partitioned antenna arrays. This can be also used in MIMO channel and eigen value decomposition (EVD).

It is considered that jacket was widespread in the 19th century due to its simple and convenient production technique. This study aims to explore the western women's jacket in the late 19th century, which is the basis of modern women's outwear, and we focused on the patterns and construction, the technical aspect of the jacket. We researched pattern books and preserved costume materials, and the study methods are as follows: First, we analyzed the pattern of the jackets from the pattern books and preserved costumes. Second, we analyzed the construction of the jackets from the preserved costumes and compared it to previous researches. The study results are as follows: 19th century jacket consisted of a bodice, a back bodice, a side panel, two-piece sleeve and a collar. The front bodice had cuttings and a dart to make the jacket fit the shape of the body and the two-pieced leg of mutton sleeve, puffed at the shoulder. Various styles of collar and neckline existed. The pattern suggested diverse ways of designing a jacket, such as cutting with partition, dart and pattern expansion that focused on three-dimensional effect at that time.

Almost prefounded columns for top-down construction certainly have construction tolerances in plan and plumbness. Therefore, it is very difficult to connect prefabricated beams to prefounded columns at each floor level after excavation by usual top-down connection method and this usual connection method leads to long construction time, increasing cost and decreasing quality. This paper presents a new method for connecting prefabricated beam to prefounded column with GROUT-JACKET CONNECTION SYSTEM consisting of sleeve, bearing-shear bands and grout. Details and illustrations of the connections and applications by GROUT-JACKET CONNECTION SYSTEM for the top-down construction are also included in this paper.

In this paper we prove that all Jacket matrices are circulant and up to equivalence. This result leads to new constructions of Toeplitz Jacket(TJ) matrices. We present the construction schemes of Toeplitz Jacket matrices and the examples of $4{\times}4$ and $8{\times}8$ Toeplitz Jacket matrices. As a corollary we show that a Toeplitz real Hadamard matrix is either circulant or negacyclic.

This study suggests a new perspective for designing men's tailored jackets by more carefully considering human muscle structure. For this study, we examined research regarding the construction of the tailored jacket that is based on costume history references, as well as research regarding human muscle structure that is based on human anatomy references and the analysis of recent fashion designs illustrating the human body image. Based on this research, we developed various tailored constructions that account for human muscle structure. These constructions are applied primarily to the backs of four tailored jackets, as the back of the jacket needs a mechanism to accommodate the wearer's movement. The following conclusions have been derived from the study: First, by developing the tailored garment structure that accounts for the muscle structure of the human body, we suggest a new design direction for tailored garments. Second, we propose a new type of tailored jacket structure for the back of the jacket that incorporates an artificial muscle structure to accommodate the wearer's activities. This new type of jacket indicates the potential for designs that use structure, particularly the structure of the human body. Finally, by using the embroidery technique, we changed the texture of the material into the shape of human muscle. Thus, we propose a design that uses three-dimensional volume to accounts for the shape of human body tissue.

In this paper, the explicit low density codes construction from the generalized permutation matrices related to algebra theory is investigated, and we design several Jacket inverse block matrices on the recursive formula and permutation matrices. The results show that the proposed scheme is a simple and fast way to obtain the low density codes, and we also Proved that the structured low density parity check (LDPC) codes, such as the $\pi-rotation$ LDPC codes are the low density Jacket inverse block matrices too.

The purpose of this study is to investigate the diverse constructive characteristics which significantly affects performance besides materials information provided to consumers on functional clothes. Outdoor jackets can classified them according to their performance level. In order to provide consumers with necessary information to choose functional outdoor jackets, 12 brands selling domestic outdoor jackets were investigated and the conclusion of this study was as follows; It was found that fit degree, backpack weight, arm-raise, and number of pockets vary differently depending on performance level of outdoor jacket. Considerable constructive difference was found between high performance jacket mainly worn by professional climbers in extreme environment and jacket that can be worn in daily life. It is found that different characteristic is related not only to each diverse & complex constructive aspect, but also to ability to stretch, resistance to water, venting system of materials depending on performance level of outdoor jacket.

This study examined the effect of various arrangement methods for forming peripheral closed hoops in the jacket section on the axial behavior of section enlargement strengthening columns. Four types of peripheral closed hoops arranged in the jacket section were prepared as follows: 1) Closed connection of prefabricated bar units (column P); 2) V-clip installation across the overlapped legs of channel-type bars (column V); 3) Use of glass fiber mesh for an alternative of steel bars (column F); and 4) combination of prefabricated bar units and glass fiber mesh (column PF). The V-clip is designed to form the closed hoops in the jacket section using the overlapped channel-type bars, preventing the opening of the channel bar legs. The glass fiber mesh is to examine the feasibility to apply for closed hoops in the jacket section as an alternative for steel bars, considering the easy construction. In the jacket section of all the strengthened columns, V-ties were arranged for supplementary ties, avoiding the interruption of the existing column. The axial stiffness and strength of the strengthened columns were insignificantly affected by the arrangement methods of closed hoops in the jacket section. The axial ductility ratio of the strengthened columns P, V, and PF was enhanced more than twice of that measured in the non-seismic existing column. However, the column F exhibited a lower ductility than the other strengthened columns because of the fracture of the mesh at the ultimate strength of the column. The V-clip approach was favorable to enhance the ductility of the strengthened column, preventing the opening of the legs of channel-type bars.

In this study, structural strain responses of the jacket-type Uldolmok tidal current power plant structure under severe tidal environments were measured and analyzed using long-term measurement system during construction and also operation. It was observed that there were significant changes in strain responses at the steps of jacket lifting, block loading, pile ejection and insertion. Strains due to dead loads and tidal loads were analyzed before and after removal of a jacket leg, and it was also found that the strains due to dead load were much significantly changed after jacket leg removal. From the measurement data during operation, it was found that strain responses were fluctuated with M2 and M4 tidal periods and also relatively short period of about 10 min due to the peculiar tidal characteristics in the Uldolmok strait. Finally, the neural network-based non-parametric estimation models were investigated to build up the signal-based structural damage monitoring system.
