Fingerprints have been widely used in the biometric authentication because of its performance, uniqueness and universality. Lately, the speed of identification has become a very important aspect in the fingerprint-based security applications. Also, the reliability still remains the main issue in the fingerprint identification. A fast and reliable fingerprint matching algorithm based on the process of the 'self-nonself' discrimination in the biological immune system was proposed. The proposed algorithm is organized by two-matching stages. The 1st matching stage utilized the self-space and MHC detector string set that are generated from the information of the minutiae and the values of the directional field. The 2nd matching stage was made based on the local-structure of the minutiae. The proposed matching algorithm reduces matching time while maintaining the reliability of the matching algorithm.

The easily accessible handheld devices equipped with camera are widely available as common commodities. According to this trend, utilization of images is popular among common users for various purposes resulting in huge amount of images in local or network based storage systems. In this environment, identification of an image with a solid and effective manner is demanded in behalf of safe distribution and efficient management of images. The generated identifiers can be used as a file name in file systems or an index in image databases utilizing the uniqueness of the identifiers. In this paper, we propose a method that generates image identifiers using linear components in images. Some experiments of generation of identifiers are performed, and the results evaluate that the proposed method has feasible effectiveness.

Variational method has played an important role in solving problems of uniqueness and existence of the nonlinear works as well as analysis. It will also be extremely useful for researchers in all branches of natural sciences and engineers working with non-linear equations economy, optimization, game theory and medicine. Recently, the existence of infinitely many weak solutions for some non-local problems of Kirchhoff type with Dirichlet boundary condition are studied [14]. Here, a suitable method is presented to treat the elliptic partial derivative equations, especially (p(x), q(x))-Laplacian-like systems. This kind of equations are used in the study of fluid flow, diffusive transport akin to diffusion, rheology, probability, electrical networks, etc. Here, the existence of infinitely many weak solutions for some boundary value problems involving the (p(x), q(x))-Laplacian-like operators is proved. The method is based on variational methods and critical point theory.

In this paper, we study a system of nonlinear wave equations associated with the helical flows of Maxwell fluid. By constructing a N-order iterative scheme, we prove the local existence and uniqueness of a weak solution. Furthermore, we show that the sequence associated with N-order iterative scheme converges to the unique weak solution at a rate of N-order.

This paper will concentrate on how various particular Southeast Asian conditions created a distinct Southeast Asian cultural identity despite a very challenging geographical and historical diversity in the region. The paper will argue that Southeast Asians demonstrate an ability to adapt to changes and new values but also exhibit fatalism through a very high degree of passive acceptance to political and other changes that affect their society. The paper identifies a degree of environmental and geographical uniqueness in Southeast Asia that shapes context and gives rise to very distinct cultural traits. The historical transformation in the region brought about by colonialism and nationalism, combined with this geographical and political make-up of the region, had an immense impact on Southeast Asian society as it fostered adaptability. Finally, the political transitions brought about by various conflicts and wars that continued to affect the area in rapid succession all throughout the 20^th century likewise contributed immensely to a local Southeast Asian fatalistic response towards change. Historically, Southeast Asia demonstrated these socio-cultural responses to such an extent that these are argued to permeate the region forming a distinct aspect of Southeast Asian culture.

We consider a mathematical model which describes the quasistatic contact of electro-viscoelastic rod with an obstacle. We use a modified Kelvin-Voigt viscoelastic constitutive law in which the elasticity operator is nonlinear and locally Lipschitz continuous, taking into account the piezoelectric effect of the material. We model the contact with a general damped response condition. We establish a local existence and uniqueness result of the solution by using arguments of time-dependent nonlinear equations and Schauder's fixed-point theorem and obtain a global existence for small enough data.

The purpose of this study is to identify characteristics of spatial structure of Jiangnan water town in China which has been developed along the water channel. Spatial structural characteristics of the water town, Wuzhen and Nanxun in Zhejiang Province are as follows. First, location of town, spatial framework, lot division, and architectural style get determined by the water channel. The water channel is constructed in cross shape, T-shape, or in combination. Secondly, public space of water town is established along main water channel. Visually and functionally alternating private buildings are established on the water channel side and they are creating unique landscape of Jiangnan water town in overall harmony. Thirdly, residential area is established on the east-west water channel side with southward sunny-faced arrangement and waterside residence is in introvert spatial structure with courtyard but the exterior space is connected with water channel intimately. Fourthly, various spatial components along the water channel enrich the sense of place in water town. The components are corridor with roof, tea house, waterside steps, waterside theater and watergate etc. Uniqueness of place is becoming the core competence in modern townscape. In this aspect, Jiangnan water town with historical and cultural accumulation is suggesting a significant implication. Major implications are as follows. First, promotion of proximity to the water is the basic value that the spatial plan of waterfront needs to pursue. Secondly, mixed use is essential for effective land use and revitalization of waterfront. Thirdly, waterfront plan based on the local uniqueness as the place asset is being required.

In late 1980s, many suburban cities in Tokyo metropolitan area have tried to construct office parks, such as Makuhari New Town, Minato Mirai 21 to promote knowledge based economy. As the most important player of this mesa project, the local government mobilized local resources from various private sectors. The local government adopted place marketing strategy to attract companies and consumers with thick pocket. The composition of this strategy embraces publicity, uniqueness, centrality of function and information and comfortability for formation of the office park. Headquarters and producer service offices were relocated in the suburban office parks for the first time in the history of modem Tokyo since 1920s. Although it is the ongoing project that encounters some financial difficulties, the office park Project will be a sound foundation for future growth of knowledge-based economy.

In smart cities around the world, urban environments have become more convenient due to information and communication technology(ICT). However, extant studies reveal that the level of life satisfaction of citizens has not improved compared to that of the pre-smart city and citizens are skeptical about the role of the smart city. This is largely because local culture and needs were neglected during the planing and development of the smart city. The research was conducted on Cambodia as a pilot site and our findings indicate that middle age group's population is significantly small and the society is at risk of losing its culture. Therefore, this paper opens up various ways of embedding cultural programs using technology in order to pass down cultural heritage to young generation, provide an emotional attachment to the inhabitants and further build up a new phase of cultural legacy. This will engender cultural uniqueness to the city and intrigue tourists around the world resulting in the growth of the tourist industry. This research will contribute locally by providing a sense of community to the public and globally by suggesting applicable methodology to other cities that are under the similar context.

Objectives : To provide foundation for research on local medical examination of the Ming period, the contents on 'He who does not know Yi(易) cannot speak of medicine' in the Yixuetongzong(醫學統宗) written by He Jian was analyzed. Methods : Proofreading of the original texts, followed by interpretation of words and phrase and translation into Korean were done. The resulting contents were then analyzed from the perspective of the theory of Medical Yi(Yi-Yi). Results : In this medical exam paper for physicians, He answers himself on topics such as the Four Symbols[四象], Eight Symbols[八象], the Sixty-four hexagrams[Liushisigua], the combinations of the Organs and Bowels[Zangfu], Nine Orifices[Jiuqiao], and Five Body Parts[Wuti], the origin of the pulse, the reasoning behind calling the pulse 'the station for blood[xuezhifu]', what the 'Tianzhen Weihezhi Qi' stands for and the meaning of the Twelve Organs[shierguan]. He also supports the perspective of the 'Medicine and Yi having the same roots[Yi-yi tongyuan]', arguing that due to this, the body's physiology could be explained through the theories of Yi[易]. This shows that He understood the Yi-yi theory as a larger category. Conclusions :He's medical exam paper reflects his uniqueness in the field of the Yi-yi theory that precedes that of Zhao Xianke.
