  • There has been an increasing interest in n since it is spotlighted as the standard for data representation and exchange in the Web. The structural information for XML documents serves several important purposes. In spite of its importance, the schema is not mandatory for XML documents. Thus, much research to extract structural information for XML document has been conducted. In this paper, we present a technique for efficient extraction of concise and accurate DTD for XML documents. By restriction of DTD content model using the mixed content model of DTD and XML Schema as well as applying some heuristic rules proposed in this paper, we achieve the efficiency and conciseness. The result of an experiment with real life DTDs shows that our approach is superior to existing approaches.

  • This paper presents a multimedia streaming platform for efficiently transmitting MPEG-4 content over IP networks. The platform includes an MPEG-4 compliant streaming server and client, supporting object-based representation of multimedia scenes, interactivity, and advanced encoding profiles defined by the ISO standard. For scalability purposes, we employ an application-layer multicast scheme for media transmission using overlay networks. The overlay network, governed by the central entity of the network distribution manager, is dynamically deployed according to a set of pre-defined criteria. The overlay network supports both broadcast delivery and video-on-demand content. The multimedia streaming platform is standards-compliant and utilizes widespread multimedia protocols such as MPEG-4, real-time transport protocol, real-time transport control protocol, and real-time streaming protocol. The design of the overlay network was architected with the goal of transparency to both the streaming server and the client. As a result, many commercial implementations that use industry-standard protocols can be plugged into the architecture relatively painlessly and can enjoy the benefits of the platform.

  • The flexibility of content addressable mem-ory (CAM) can greatly be extended through the use of trits (ternary digits) Trits consist of binary logical values “0” and “1” with addition of “x” (“dont’t care”). The “dont’t care“is extremely useful for providing com- pact representation of sets of bit strings. In this paper, we propose a new ternary CAM with Hamming distance search functions. Each memory cell in the CAM consists of a pair of lambda diodes which can store trits, namely, a logical “0”, “1” and “x” (“dont’t care“). The CAM can compare stored data and an input data in parallel, and find stored data with Hamming distance within a certain range (“near match“). Also, the interrogation characteristics of the ternary CAM are analyzed in detail. Furthermore, the results obtained these analyses are fully confirmed by simulation using the circuit analysis program HSPICE.

  • Purpose: Distributed leadership (DL) is a comprehensive and analytical way to understand how leadership manifests itself among people and in the context of a complex organization. With technological advances and seemingly ever-changing pressures on the environment, it is important for education leaders to represent their practice. This study aims to discuss the significance of DL and its role in education. Research design, data and methodology: The present researcher used Qualitative Content Analysis (QCA) because it is credible, transferable, dependable, and confirmable proving its trustworthiness. To begin with, QCA entails a sufficient representation of the social realities being studied, credibility. Results: The investigation of this study indicates that the documents are in the proper functioning of schools to highlight the potential impact of collaborative practices, many of which require sharing school fees. DL can be meant as "influence relationships," discussions in groups, government, and non-leaders, about how teachers influence each other, and teamwork was easy. Conclusions: This study suggests that management can significantly impact organizational changes in management practices to distribute or skip something planned. DL is not a panacea, plan, or formula. Rather, it is a way to get under the skin of local leadership and restore the potential for change in the organization.

  • Multilingual Knowledge Graphs (MKGs) have emerged as a crucial component in various natural language processing tasks, enabling efficient representation and utilization of structured knowledge across multiple languages. One can get data, information, and knowledge from various sectors, like libraries, archives, institutional repositories, etc. Variable quality of metadata, multilingualism, and semantic diversity make it a challenge to create a digital library and multilingual search facility. To accept these challenges, there is a need to design a framework to integrate various structured and unstructured data sources for integration, unification, and sharing databases. These are controlled using linked data and semantic web approaches. In future, multilingual knowledge graph overcomes all the linguistic nuances, technical barriers like semantic interoperability, data harmonization etc and enhance cooperation and collaboration throughout the world. Through a comprehensive analysis of the current state-of-the-art techniques and ongoing research efforts, this paper aims to offer insights into the future directions and potential advancements in the field of Multilingual Knowledge Graphs. This paper deals with a multilingual knowledge graph and how to build up a multilingual knowledge graph. It also focuses on the various challenges and opportunities for designing multilingual knowledge graphs.

  • The purposes of this study are to examine what the participants experienced when developing Content Representation (CoRe) of "molecular motion" for the 7th grade in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher and to investigate how the participants' PCK changed in their classes after developing CoRe. The participants were one experienced chemistry-trained teacher, two physics-trained teachers, and one researcher. The participants were selected by purposeful sampling. For this study, the discussions on developing CoRe was recorded and two physics-trained participants' classes were video-taped, and constructed/semiconstructed interviews were conducted. All data were transcribed for analysis. The participants experienced reflective thinking of their knowledge and previous classes, corrected their own misconception and clarified those conception, recognized the contents and the goals of "molecular motion" class, enhanced understanding of students' preconception during the development of CoRe. Especially, the two physics-trained teacher-participants confessed that they recognized clearly the contents and the goals of "molecular motion" class and identified their deficiency in 'particle viewpoint' in their previous classes. Their recognition was realized in the course of interaction with experienced chemistry-trained teacher. Among the components of PCK, knowledge of science curriculum was most influent on two physics-trained teacher-participants' classes, and they emphasized 'particle viewpoint' and 'molecular motion' in their classes. In addition, they introduced new teaching strategies that were discussed in the course of developing CoRe. The influence on the participants' PCK was different according to their reflective thinking on their own knowledge and previous classes and their affective characteristic. The implication of this study is that, the course of developing CoRe can promote reflective thinking that is essential for increasing teachers' professionalism and significantly influence on PCK. Especially, developing CoRe in collaboration with experienced chemistry-trained teacher and non-chemistry-trained teacher can identify deficiency in their classes and thereby, improve their classes. And, it takes time and effort to internalize the participant's recognition in their teaching practice.

  • Freed from its traditional confinement to the human body, postmodernism in fashion exposes the defectiveness of body and abstracts from the body under. Deformation of the body denotes the break away from the idealized and standardized body for mass productions. It tends to experiment with extreme exaggeration in form, refusing to subscribe to the traditional values that build on the balance and symmetry of the body. Bodily deformation carried out historical and cultural pastiche opposes the sartorial convention and symbolism which results in the discord between signifiant and $signifi{\acute{e}}$ of clothing. As a type of intimate architecture, fashion always mediates the dialogue between clothes and body, or fashion and figure. My study suggests a framework to analyze bodily deformation as pastiche, focusing on the relationship between clothes and the body. In order to inquire the deformation of the body in fashion, my study examines subjects of the fashion collections of the turn of the 21st century, using the method of literature research and content analysis.

  • In this paper we propose the CBIR algorithm which is based on a novel image block method that combined both color and edge feature. The main drawback of global histogram representation is dependent of the color without spatial or shape information, a new image block method that divided the image to 8 related blocks which contained more information of the image is utilized to extract image feature. Based on these 8 blocks, histogram equalization and edge detection techniques are also used for image retrieval. The experimental results show that the proposed image block method has better ability of characterizing the image contents than traditional block method and can perform the retrieval system efficiently.

  • In this paper we describe an application of the lexical resource JurWordNet and of the Core Legal Ontology as a descriptive vocabulary for modeling legal domains. It can be viewed as the semantic component of a global standardisation framework for digital governments. A content description model provides a repository of structured knowledge aimed at supporting the semantic interoperability between sectors of Public Administration and the communication processes towards citizen. Specific conceptual models built from this base will act as a cognitive interface able to cope with specific digital government issues and to improve the interaction between citizen and Public Bodies. As a Case study, the representation of the click-on licences for re-using Public Sector Information is presented.
