Different scale of information is an important component in computer vision systems. Recently, there are considerable researches on utilizing multi-scale information to solve the scale-invariant problems, such as GoogLeNet and FPN. In this paper, we introduce the notion of different scale information fusion (DSIF) and show that it has a significant effect on the performance of object recognition systems. We analyze the DSIF in several architecture designs, and the effect of nonlinear activations, dropout, sub-sampling and skip connections on it. This leads to clear suggestions for ways of the DSIF to choose.

The purpose of this study was to examine strategies which clothing manufacturers had employed to make themselves more competitive in the era of fast fashion. The Zimbabwean fashion industry is facing fierce competition from imported fast-fashion products which are lower priced and offer consumers a variety of designs from which to choose. The study made use of a qualitative approach with multiple case study design. In-depth interviews were used to gather data from participants, who were selected using the purposive sampling. The study found that clothing manufacturers had resorted to sub-contracting garment manufacturing work, promoting the buy-Zimbabwe campaign and developing in-house brands. This study offers insights into how the fast-fashion era has impacted the local fashion industry and unveils the practical solutions that local clothing manufacturers have embraced in a bid to remain operational and become globally competitive.

The purpose of this study was to determine the preference and purchasing intention on necktie pattern designs according to male consumers' fashion lift style. Written questionnaires were handed out to 300 male consumers of the 20-40 years old in Seoul and surroundings, who were accessed by a convenience sampling method. The questionnaires were to classify male consumer groups according to the fashion life style, to examine characteristics, needs and wants of each group. The stimuli of 8 kinds of necktie patterns in black & white, and the semantic differential scale were applied to evaluate the preference and purchasing intention on necktie pattern design. A total of 265 samples were analyzed by factor analysis, cluster analysis, ANOVA, crosstabs and $X^2$-test through SPSS package program. Six factors in their fashion life style were extracted as follows: those were 'fashion-oriented', 'traditional conservative', 'brand-flaunting', 'personality-oriented', 'practicality-oriented' and 'unconcerned' life style. With these life style sub-dimensions, male consumers were segmented into five groups: these groups were 'strong personal seekers', 'practical brand seekers', 'traditional personal seekers', 'active fashion seekers', 'unconcerned group'. Each of these groups of male consumers showed significant differences in the preference and purchasing Intension of necktie pattern designs according to their fashion life style.

This study aims to establish the standards to give the design weight in case when developing equipment designs, by classifying products with similar purposes in accordance with the morphological characteristics and also extracting the typicality. Limiting the sampling group for the extraction of the typicality to a pendant-type and a ceiling buried-type through the preceding case study and consultation with experts, the survey was conducted for majors and relevant workers in six cities, sampling products released in Korea and Japan before May 2016. The 1st survey was about the Morphological classification, and the 2nd times about the extraction of the typicality while the 3rd one was about the classification of the morphological attributes. By drawing the design attributes based on the functional/morphological classification and formative principles, it aimed to establish the base of the future research on the measurement of design weight. The results of this study aim to efficiently establish the roles of design technology in accordance with changes in the lighting fixture market caused by the substitution of light sources, and also to draw the development direction to rapidly cope with the accelerated changes in lighting design types and corporate R&D.

This study provides basic data for the development of jacket patterns which reflect designs corresponding to the body shape features and preferences of obese women in their 20s and 30s by understanding problems they may encounter in wearing a ready-made jacket by researching the reality of ready-made tailored jacket wearing and their design preferences. A survey was conducted by sampling 82 obese women (over $25kg/m^2$ BMI) between the ages of 20 to 39. The details of the survey consists of general information, interest rate and importance rate on clothes, reality of wearing and purchasing jackets, measurement fits per each part, and preferred designs. SPSS 14.0 was used to analyze the data. The results showed that 76.8% of obese women wore their jackets less than 5 times a month. Those in the 20s wore the jackets more frequently than those in the 30s. The reasons for not wearing jackets frequently included uncomfortableness in activities and unavailability of the correct size. A total of 55% of the total preferred the fitting to be relatively smaller than the body size or tightly fitting. Although in the past, there was a tendency to wear a loose fit to cover the body shape, currently even obese body shapes avoided the loose fit as the tight fit is the trend. In terms of the satisfaction rate for the measurements per each part of jackets, there was a low satisfaction rate for most of the items. For the circumference items such as waist length and chest size, people responded that they were too small and for the length of items such as the length of jacket and sleeve length, people responded that they were too long. This was because the readymade clothes brands increase the length of items and circumference items in uniform in the same intervals when producing large sizes. Both those in the 20s and the 30s preferred a tight fit. In terms of preferred fabric, a wool/spandex mix was most popular and then cotton/spandex. This shows that they prefer those fabrics which allow an excellent activity while maintaining the exterior well. In addition, they preferred black color with no patterns because they wanted their body size to look reduced and did not want to receive any attention.

Monopiles have been most widely used for supporting offshore wind turbines (OWTs) in shallow water areas. However, multi-member lattice-type structures such as jackets and tripods are also considered good alternatives to monopile foundations for relatively deep water areas with depth ranging from 25-50 m owing to their technical and economic feasibility. Moreover, jacket structures have been popular in the oil and gas industry for a long time. However, several unsolved technical issues still persist in the utilization of multi-member lattice-type supporting structures for OWTs; these problems include pile-soil-interaction (PSI) effects, realization of dynamically stable designs to avoid resonances, and quick and safe installation in remote areas. In this study, the effects of PSI on the dynamic properties of bottom-fixed OWTs, including monopile-, tripod- and jacket-supported OWTs, were investigated intensively. The tower and substructure were modeled using conventional beam elements with added mass, and pile foundations were modeled with beam and nonlinear spring elements. The effects of PSI on the dynamic properties of the structure were evaluated using Monte Carlo simulation considering the load amplitude, scouring depth, and the uncertainties in soil properties.

This paper sketches the strategies and designs for monitoring system of swine genetic improvement. The system should reflect every side of pig production. The system leads us to assess the efficiency of pig production and the scope of the system includes not only nucleus, multiplying and commercial herds, but also packing and processing sectors. For more accurate statistics, data for this monitoring system must be collected from all above mentioned areas, but not by random sampling. Futhermore, data analysis results including seedstocks and distribution information of genetic trend should be included in the system. The schema of knowledge database system could be employed in the system. The monitoring system in the final destination would unify the systems derived from various sources and provide any solution in swine industry including pig breeding.

Energy systems working coherently in different conditions may not have a specific design which can provide optimal performance. A system working for a longer period at lower efficiency implies higher energy consumption. In this effort, a methodology demonstrated by a jet pump design and optimization via numerical modeling for fluid dynamics and implementation of an evolutionary algorithm for the optimization shows a reduction in computational costs. The jet pump inherently has a low efficiency because of improper mixing of primary and secondary fluids, and multiple momentum and energy transfer phenomena associated with it. The high fidelity solutions were obtained through a validated numerical model to construct an approximate function through surrogate analysis. Pareto-optimal solutions for two objective functions, i.e., secondary fluid pressure head and primary fluid pressure-drop, were generated through a multi-objective genetic algorithm. For the jet pump geometry, a design space of several design variables was discretized using the Latin hypercube sampling method for the optimization. The performance analysis of the surrogate models shows that the combined surrogates perform better than a single surrogate and the optimized jet pump shows a higher performance. The approach can be implemented in other energy systems to find a better design.

The steam generator feedwater and level control system is designed by two steps of the feedwater control design and the feedback loop controller design. The feedwater sen system is designed by the optimal LQR/LQG approach and then is modified by the LTR method to recover the robustness. The plant characteristics are subject to change with the power variation and these dynamic properties are considered in the design of the feedback controller. All the designs are made in the continuous domain and are digitalized by applying the proper sampling period. The system is simulated for the two cases of power increase and decrease. From the results of simulation, it is found that the controller constants would rather be invariable during the power increase, while for the case of power decrease they should be changed with the power variation to keep the system stability.
