Many real networks exhibit overlapping community structures. Recent studies have been performed that analyze the impact of overlapping community structure on information propagation, but few of them concerned with individual behaviors. From this point of view, we propose a Markov process model to evaluate the performance of information propagation in social networks with overlapping community structures. In addition, many individual social behaviors are combined in the model. For example, individuals may exhibit selfish behaviors, such as individual and social selfishness, and people may discard the information after they have used it. The accuracy of the model is verified by simulation. Furthermore, the numerical results show that both overlapping community structure of the network and individual behaviors have a significant impact on the outbreak size and propagation speed of the information. Additionally, the overlapping community structure of the social network can reduce the impact of selfishness on information propagation.

This study attempted to figure out the usage of the modular system in other fields through literature review and empirical study, analyze its structural method in fashion. After analyzing architecture & product-related books, the Internet data and previous studies, the modular system's five structural methods were obtained. Then, 991 photos of women's clothes from 2003 to 2014 were collected through the fashion websites in Korea and abroad. The results can be summarized as follows: First, the following five structures were derived: assembling structure, overlapping structure, arrangement structure, inserting structure and folding structure. Second, according to analysis on the structural method of the modular system in modern fashion, overlapping structure (34%) was the most common. Third, in fashion, the use of fastener for installation and removal is important for assembling structure. In terms of overlapping structure, 3D volume by vertical accumulation was commonly observed. Arrangement structure revealed a horizontal and flat shape through simple arrangement. In inserting structure, on the contrary, non-standardized modules were used as a part of clothes or decorative elements. In folding structure, origami technique for reduction and expansion was used.

This paper presents design criteria of an overlapping decentralized controller by investigating the controllability and closed loop stability of the expanded system. To determine the criteria we classify the overlapping decentralized controller into an overlapping expanded controller and a contractible controller. It is shown that conditions of system expansion to design these controllers are differently used. The overlapping expanded controller needs the aggregation conditions due to the importance of a structure of the expanded system. The contractible controller which intends to use in the original space needs the restriction because of stability of the original system.

Lately in many cases, Spaces are designed by stimulating user's sensibility, emotion, psychological software over based on the user behavior and purpose of space. Because space is not only practical using and use purpose but also the place for expressing ourselves by experiences. But space is a physical thing. so we need to arrange a structure of abstract and formless source of design by sophisticated grammaticalization. Especially storytelling of that abstract thing have characteristics of relation, process among users and space. because storytelling is focused on the discourse of stories and relationship record of that discourses. So this is used by expression device for user's emotion things and subjects in numerous cases. And storytelling is the basic, important element for user's experience in a space. By the way, Overlapping is also basic element for being possible to make experiences by concrete thing. that is because, Overlapping is layering phenomenon of some objects. Overlapping is made distance, distance make depth, and this relations take us an experience. Finally storytelling, Overlapping and space of experience are relation of cause and effect. So in this thesis, researcher looks for the relation characteristics between storytelling and overlapping by experience. and makes the abstract source into concrete and sophisticated formular.

This paper proposes a reconstruction scheme for overlapping characters in Thai printed document. Overlapping characters are characters that overlap with surrounding characters. The problem of overlapping characters is still an unsolved problem In commercially available software of Thai character recognition systems. The algorithm of reconstruction scheme is based on structural analysis of overlapping Thai printed characters. It consists of 2 steps: overlapping point determination and reconstruction of segmented characters. The overlapping point is defined as the intersection point between characters and can be determined by using templates. Then, an overlapping character is separated into segments at the intersection point. The structure of each segment may be an incomplete character and is not identical to the original one. Therefore, the reconstruction process is employed to add the incomplete part of these segments. The proposed scheme has been implemented and tested with 70 patterns of conventionally found in overlapping printed Thai characters with different typefaces and type sizes. The experimental results show that the proposed scheme can segment and reconstruct overlapping characters correctly. The proposed scheme can improve the recognition rate of commercially available software, ThaiOCR1.5 and ArnThai1.0, more than 60 percents

This study was intended to define the spatial concept of the boundary structure of the architectural space as well as evaluate the Hyangdan which well represents the features of Korean traditional building in such a way of reviewing the building structure of Korean traditional residential space. The boundary is categorized into visible boundary and invisible boundary which was also functionally classified into the features of isolating, passing, mediating and overlapping. The major elements comprising the boundary structure was analyzed by the characteristic of the pattern so as to define them as the concept of surrounding, duality, hierarchism, continuity and overlapping. Based on such concepts, a boundary structural characteristics of Hyangdan were reevaluated and outlined as follows. The surrounding feature was seen through the outer side of the structure surrounded, two courtyards and eaves, and a duality showing both the closure of main house and openness of detached house was seen through the characteristics of surrounding structure. And the continuous activities toward the inner room and the empty space to link them in a systematic way and repeatedly aligned rooms reveal the overlapping as continuous and transitional space. And finally, an elevated stylobate demonstrates the hierarchical features of the structure.

A diode-pumped Nd:$YVO_4$ laser was used to obtain indium tin oxide (ITO) patterns on glass substrate with various overlapping rates. The results showed that the overlapping rate of laser beam influences on the edge structure of ITO pattern and the surface roughness of ablated groove bottom. At a laser repetition rate of 40 kHz, the optimized condition of overlapping rate was 75 %.

An experiment was carried out on the structure of twin spray from pressurize-swirl nozzles, in order to investigate the effect of different size of spray nozzles on the characteristics of the overlap of two single sprays, for example, mean diameter, number density, and spatial distribution of flow rate. Using image processing method, the distributions of size and velocity of droplets of a single spray and twin spray were measured and compared to investigate the overlapping effect of two identical sprays. Comparing experimental results from a twin-spray with those from two-single sprays shows that the flow rate distribution of the twin-spray was concentrated around the midst of the overlapping region of two sprays. In this region, Sauter mean diameter (SMD) did not change much in the twin spray from 6032 nozzles, but it was smaller by 10 micrometers in the twin-spray than two-single sprays from 60063 nozzles. In spite of large difference in Weber numbers of the colliding sprays between the 60063 and 6032 nozzles, the phenomena did not have a big change in the overlapping region of twin spray. This shows that in the collision between droplets from two single spray in the overlapping region to cause the disruption of droplets, the size distribution of spray droplets was also important as well as Weber number.

Hydrodynamic coefficients strongly affect the dynamic performance of autonomous underwater vehicles (AUVs). A novel kind of underwater vehicle (Heavier-than-water AUV) with higher density than water is presented, which is different from conventional ones. RANS method and overlapping grids are used to simulate the flow field around the vehicle. Lifts, drags and moments of different attack and drift angles in steady state are calculated. The hydrodynamic performances and how the forces change with the attitude are analyzed according to the flow field structure. The steady-state results using overlapping grid method are compared with those of software FLUENT and wind tunnel tests. The calculation results show that the overlapping grid method can well simulate the viscous flow field around the underwater vehicle. Overlapping grid skills have also been used to figure out the planar-motion-mechanism (PMM) problem of Heavier-than-water AUV and forecast its hydrodynamic performance, verifying its effectiveness in dealing with the dynamic problems, which would be quite helpful for design and control of Heavier-than-water AUV and other underwater vehicles.

This paper presents a decentralized controller design for formation flying of multiple satellites based on the overlapping decomposition technique. Each satellite is assumed to avail only the information of its own and in front of itself, which restricts the structure of a controller gain matrix to an overlapped form. The concerned large-scale system is expanded using the overlapping decomposition technique. Design condition is represented in terms of linear matrix inequalities with small-scale systems in a decentralized form, based on the expanded system. The resulting controller is contracted to the original overlapped form so as to close the original system. A numerical simulation shows the effectiveness of the proposed technique.
