  • The mobile computing has been a main mean of computing, because of recent development of smartphone and mobile communication network. The new service technologies, such as cloud computing, big data, SDN (Software Defined Network), and NFV (Network Function Virtualization), are appearing due to activating of the data center. These changes have brought various requirements for transport layer protocol. In addition, the transport protocol should have a extensible function to adapt additional technologies. This paper proposed that transport layer divide into three layer structure for extensible function, and designed the ETP(Extensible Transport Protocol) which is located in the bottom layer.

  • In this paper, we study the long-time dynamical behavior for the extensible suspension bridge equations with past history. We prove the existence of the global attractors by using the contraction function method. Furthermore, the regularity of global attractor is achieved.

  • Extensible elastica solutions of two-dimensional deflection of crimped fiber cantilever of circular wavy crimp were obtained for one end clamped boundary under concentrated, inclined and dead tip load Fiber was also regarded as a linear elastic material. Crimp was described as a combination of semicircular arcs smoothly connected with each other having con­stant curvature of all the same magnitude and alternative sign. Also the inclined load direction was taken into account. The solutions were expressed as the recursive forms of integrals in two different cases, which can also be transformed to elliptic integrals respectively. Comparing the data with inextensible ones was carried out. Consequently in the solution, the normal strain of neutral axis is expressed in terms of cross-sectional area, second moment of area and normalized load parameter. Examples of the circular cross-sectioned fiber are presented. As a result, the differences of normalized load between inexten­sible and extensible elastica solutions when the radius ratio becomes 0.1 were maximum $\Lambda$ = 0.1.

  • In a reinforced soil structure, the interaction between soil and an reinforcement occurs due to the frictional resistance on the contact surface between them or the pullout resistance of the reinforcement. Generally, a pullout test is conducted to measure pullout parameters of extensible geogrids. The factors affecting the pullout parameters in a pullout test include a density of backfill, shape of reinforcements, overburden pressure, length of spread reinforcements, and so on. The purpose of this study is to suggest a length of the spreading of an extensible reinforcement that can be used in estimating suitable pullout parameters of a pullout test. To this end, a pullout test was carried out. For the test, the length of spreading of an extensible reinforcement was set as 32 cm, 52 cm, 72 cm, and 100 cm, and effects of the lengths on pullout parameters were analyzed. As a result of the pullout test, it was confirmed that the frictional resistance between the soil and the reinforcement increases with the increase of the length of the reinforcement.

  • The modern softwares have features of modularity and extensibility, and there are several researches on extensible programming languages and compilers. In this paper, we introduce Argos programming language, which provides the extensibility with the concept of plugin languages. A plugin language is used to define a method of a class, and the plugin language processors can be added and replaced dynamically The plugin languages may be used to support multiparadigm programming or domain specific languages.

  • This paper is about the architectures of an extensible and scalable home automation system which is based on instant messaging. The extensibility is the most important feature of the system because there are very diverse appliances at home and they can be added or replaced with other products frequently. For the extensibility, we propose façade architecture for communication, distributed agent architecture for the system, layered architecture for agents, and bridge architecture for wrapping existing facilities. Using these architectures, we reduce the system complexity and get the extensibility to add new products with least cost. Furthermore, we also introduce our prototype system and show that it is extensible.

  • Containment queries for XML documents is one of the most important query types, and thus the efficient support for this type of query is crucial for XML databases. Recently, object-relational database management system (ORDBMS) vendors try to store and retrieve XML data in their products. In this paper, we propose an extensible index to support containment queries over the XML data stored as BLOB type in ORDBMSs. That is, we describe how to implement the index using the extensibility feature of an ORDBMS, and describe its usage.

  • Recently reinforced retaining walls secure their position as a stabilized method of construction replacing concrete retaining walls gradually. However, in the event of using extensible reinforcement, a bulging phenomenon can be happened in the front of reinforced retaining walls. Bulging of reinforced retaining walls means a phenomenon that, in the height of an arbitrary block, the upper part and the lower part of the block don't secure a relative position in design. Therefore, it is judged that it has the necessity to be examined in design since reinforcement needs metamorphosis to some degree to display tensile force. Therefore, the study examined about how extensibility of reinforcement had an effect on movement of reinforced retaining walls through a small-scale model test with aluminum rods. The study used Changhoji(traditional korean paper made from mulberry bark) as inextensible reinforcement and membrane as extensible reinforcement. As the result of the test, rigidity of reinforcement had a lot of effects on displacement of reinforced retaining walls and generally occurrence point of the maximum horizontal displacement had a tendency transferring to the upper part of walls according to rigidity of reinforcement was increased.

  • XML(extensible Markup Language) of W3C(World Wide Web Consortium) that is used the standard core technology of data exchange on the current Internet is an independent data type of usable at the all platforms. Especially, it can handle rapidly because of the integration of each other data types that is exchanged. Between each application and system that built at an enterprise in the past. However, W3C had notice to use XSLT(extensible Stylesheet Language Transformation) that is document transformable standard to descript expression information in XML documents because documents of XML only have a logical structure information. It is designed for XML that is developed for data exchange on the internet. Moreover, it is proposed to process and to change as other data type for expression XML documents for user. This thesis design and implement XSLT document editing system transformable as a un data type as a HTML data type applying XSLT at XML and developed the system. It can edit XSLT document that descript expression information in XML document that is used for data editing in the WYSIWYG environment.
