In many domains concept definitions undergo change on a relatively frequent basis. Especially in law, such changes can have far reaching consequences. Existing ontology versioning techniques often do not consider that old and new definitions may need to co-exist side by side in a knowledge base, or they require non-standard language extensions. In this paper we present a description logic based...

We develop a coupling technique for analyzing online models by using offline models. This method is especially effective for a growth-deletion model that generalizes and includes the preferential attachment model for generating large complex networks which simulate numerous realistic networks. By coupling the online model with the offline model for random power law graphs, we derive strong boun...

In this paper the development of system-level optical models that can be used e.g. for simulating entire laser projection systems is presented. After a short motivation ray optics as the simplest theory of optics is introduced. For the general case of tracing non-meridional rays in 3-D space the vector forms of the law of refraction and the law of reflection are provided, which lend themselves ...

The tracking of a four dimension super chaotic system with unknown parameters and uncertain static functions is researched in this paper and a robust adaptive tracking law is designed according to the Lyapunov stability theorem. Especially, the multi-unknown functions and parameters are solved by designing of adaptive turning law. It is a meaningful method both in theory and in engineering prac...

In this paper, we propose enhanced constant power panning (CPP) law which improves sound localization accuracy for two channel and multi-channel surround speaker layouts. Conventional CPP laws have different sound direction from panning angle, especially when the speakers are spread out widely. To overcome this drawback, we define a target angle and derive it by using directional psychoacoustic...

Despite its rapidly growing and dynamic nature, the Web displays a number of strong regularities which can be understood by drawing on methods of statistical physics. This thesis finds power-law distributions in website sizes, traffic, and links, and more importantly, develops a stochastic theory which explains them. Power-law link distributions are shown to lead to network characteristics whic...

Japan has been behind the times in terms of promoting smoking control. The health-promotion law, which included the aim of preventing environmental tobacco smoke (ETS) in public places, was newly introduced in Japan in 2003. The community-based survey on the present state of restaurant smoking restrictions and restaurant owners' concern of smoking is important as it is a reflection of the commu...

Compared to the past decades, in recent decades, environmental and hygienic conditions in the Republic of Korea have improved along with socioeconomic developments, and the incidence of most infectious diseases, especially vaccine-preventable diseases, has greatly decreased due to active immunization with the developed level of health care. However, the incidence of some diseases has been incre...

Recently communications and information technology became widely used in various aspects of life. The internet becomes the main network for information support. Using of internet enabled public and private organizations to develop its business and expand its activities. Private organizations applied the principles of e-commerce to improve the quality of services which provided to customers. Whi...
