  • XML is the standard for storing and exchanging information in the Web. As the applications of XML become more widespread, the worts on rule-based technology are rapidly going on to support reactive functionality on the XML documents and the XML repositories. Active rules consist of event-condition-action, which automatically perform actions in response to status change of database. Therefore the feature of active rule satisfies the new needs in XML setting. In this paper, we propose not only a XML based active rule language to manage XML document automatically, but also an active rule analysis method to guarantee rule termination. Finally, we demonstrate some examples of active rule defined by the proposed rule language, and also verify the efficiency of our analysis method by comparing with another method.

  • To efficiently manage data varying over time and process event driven transactions, some of the various database applications recently emerged require database systems supporting both a temporal data model and active rule processing. There has been much progress in independent research on temporal databases and active databases, but studies on databases which support both functions, have been rare. In this paper, an active temporal rule model supporting both active rule processing and temporal data model is presented with its rule expression language. This active temporal rule model contributes to the active function extension of the temporal database, and to establishing the concept of data access events which refer temporal attributes of data in active rules.

  • In this paper, we suggest the active multi-agent middleware for the sensor network application. For this, firstly we design and implement the active rule based mobile agent middleware. The mobile agent in the proposed system visits the destination sensor nodes according to the migration list offered by the meta table in the name space of the naming agent, acquires and transmits sensor data according to the purpose and needs through the active rules, and directly executes the actions corresponding to the optional events(changed sensor data and/or time etc.). And then, we show the potential applicability of the active rule based mobile agent middleware in various active sensor networks through the interaction with the rule base system and context database system.

  • This paper propose an active rule and its semantic model integrating active rule system into temporal database. Most of previous works have been focused on condition action(CA) rule for temporal relations. However, proposed active rule model supports full SQL:3 trigger functionalitics including transition variable and table as well as tuple-level and statement-level active rules in E CA granularity. A bi-temporal concept of active rule and valid time event are also proposed newlv.

A Case Study on the Limitations of the Choice of Law caused by Internationally Mandatory Rules in Entering into the Turn-Key Contracts (턴키계약체결시 국제적 강행규정에 의한 준거법 제한에 관한 사례연구 - Clough Engineering Ltd v Oil & Natural Gas Corp Ltd 사건을 중심으로 -)

  • This article examines the limitations of the choice of law caused by Internationally Mandatory Rules in Entering into the Turn-Key Contracts. In June 2007, Clough Engineering, a corporation based in Western Australia, approached the Federal Court of Australia seeking injunctive relief and leave to commence proceedings against an entity located outside Australia, the Oil & Natural Gas Corp of India (ONGC). Clough had contracted with ONGC to provide a range of services in relation to the construction of gas and oil wells off the coast of India. The contract was governed by Indian law, and included a clause by which the parties agreed to submit their disputes to arbitration. Yet the Federal Court assumed jurisdiction over the dispute, principally because Clough had framed its claim as a plea for relief for contraventions of Australia's Trade Practices Act 1974. The result of this cases that it is possible for an arbitral tribunal to hear a claim made under the Trade Practices Act even if that claim arises "in connection with"a contract the proper law of which is not the law of Australia. However, in Transfield Philippines Inc v Pacific Hydro Ltd, the turnkey contract included a choice of law provision, selecting the law of the Philippines, and a clause providing that all disputes arising out of or in connection with the agreement were to be arbitrated under the ICC Rules, with the seat in Singapore. Hearings were in fact conducted in Melbourne, Australia, although all awards were published in Singapore. The result of this cases that it would not be appropriate for an Australian court to adjudicate claims for misrepresentation under Australian statutes dealing with misleading and deceptive conduct, once the arbitral tribunal had determined, applying appropriate choice of law rules, that such claims are governed by the law of the Philippines. To do so would lead to a multiplicity of proceedings, usurp the jurisdiction of the tribunal and deny the intention of the parties as expressed by them in the arbitration agreement. In short, the Internationally Mandatory Rules as an active part of public order create limitation of party autonomy in choice of law rules in a different way. The court is fully entitled to refuse to use those rules of law applicable on the contract which are in the contradiction to the internationally mandatory rules of law of the forum. And the court may give an effect to those Internationally Mandatory Rules that form a part of a law of foreign country when deciding about applicability of certain rules of applicable law.

  • As the disputes in the investment and civil/commercial sectors of China and Taiwan have increased due to active cross-strait economic exchanges, the Chinese government is addressing cross-strait disputes through various dispute resolution methods. In recent years, the Arbitration Center Across the Straits (ACAS) has been established to resolve disputes between cross-strait parties, while ACAS Arbitration Rules have been enacted and enforced. ACAS Arbitration Rules are prepared by referring to the Arbitration Act of China and Taiwan, the relevant provisions and practices of the China International Economic and Trade Arbitration Commission (CIETAC) Arbitration Rules and the cross-strait practical affairs of the China International Economic and Trade Arbitration Commission, and the cross-strait practical affairs giving consideration to the specificity of the cross-strait relationship and the characteristics of economic and trade disputes. Therefore, this paper has compared the features and main contents of the ACAS Arbitration Rules with those of the CIETAC Arbitration Rules. This refers to arbitration proceedings such as form and effect of arbitration agreement, decision of place of arbitration, and organization of arbitral tribunal; the provision of consolidation of multiple contracts and arbitration, and the provision of joinder of arbitration parties, which are implementing the "principle of party autonomy" with streamlining arbitration proceedings and reducing costs; "common, simple, and small sum arbitration proceedings which require shorter arbitration proceedings depending on the size of the arbitration object; and regulations on the "interconnection of mediation and conciliation" which is characteristic of China's arbitration system. Based on the above-mentioned main contents of the ACAS Arbitration Rules in China, there are some implications to be considered in the establishment of the Arbitration Rules of the South-North Commercial Arbitration Commission which will be applied to solve commercial and investment disputes arising from the Inter-Korean Economic Cooperation process, suggesting implications such as the need for the rapid composition and operation of the South-North Commercial Arbitration Commission, requirements for selecting arbitrators, expansion of the object of arbitration, specification of concreteness in deciding the place of arbitration, need to create a variety of arbitration proceedings, and application plan of the International Center for Settlement of Investment Dispute (ICSID) or Third Power Arbitration Agency.

  • We present the technique that automatically generates caricatures from input face images. We get the mean-shape of training images and extract input image's feature point using AAM(Active Appearance Model). From literature of caricature artists, we define exaggeration rules and apply our rules to input feature points, then we can get exaggerated feature points. To change our results into cartoon-like images, we apply some cartoon-stylizing method to input image and combine it with facial sketch. The input image is warped to exaggerated feature point for final results. Our method can automatically generate a caricature image while it minimizes user interaction.

  • This paper propose a fuzzy inference model for map building and navigation for a mobile robot with an active camera, which is intelligently navigating to the goal location in unknown environments using sensor fusion, based on situational command using an active camera sensor. Active cameras provide a mobile robot with the capability to estimate and track feature images over a hallway field of view. In this paper, instead of using "physical sensor fusion" method which generates the trajectory of a robot based upon the environment model and sensory data. Command fusion method is used to govern the robot navigation. The navigation strategy is based on the combination of fuzzy rules tuned for both goal-approach and obstacle-avoidance. To identify the environments, a command fusion technique is introduced, where the sensory data of active camera sensor for navigation experiments are fused into the identification process. Navigation performance improves on that achieved using fuzzy inference alone and shows significant advantages over command fusion techniques. Experimental evidences are provided, demonstrating that the proposed method can be reliably used over a wide range of relative positions between the active camera and the feature images.

  • In this paper, we design a Linear Quadratic Gaussian controller for the active suspension. We can improve the inherent suspension problem, trade-off between the ride quality and the suspension travel by selecting appropriate weights in the LQ-objective function. Because any definite rules for selecting weights do not exist, we use an optimization-algorithm, Evolution Strategy (ES) to find the proper control gains for selected frequencies, which have major effects on the vibrations of the vehicle's state variables. The frequencies and proper control gains are used for the neural network data. During a vehicle running, the trained on-line neural network is activated and provides the proper gains for non-trained frequencies. For the full-state feedback control, Kalman filter observes the full states and Fourier transform is used to detect the frequency of the road.

  • MJ0684 from Methanococcus jannaschii is a hypothetical protein belonging to the subfamily Ig of amino acid aminotransferases. In the present study, the crystal structure of MJ0684 has been determined at 2.2 resolution. It reveals that MJ0684 has an overall structure similar to subfamily Ig aminotransferases and its active site architecture is most similar to that of kynurenine aminotransferases among several kinds of aminotransferases in the subfamily Ig?. It has two hydrophobic active site residues conserved in the kynurenine aminotransferases for recognizing hydrophobic substrates. In addition, the absence of any basic residue for recognizing the side chain carboxylic group of the aspartate in the active site rules out the possibility that MJ0684 would act as an aspartate aminotransferase. These structural observations collectively imply that MJ0684 is a novel archaeal homolog of the subfamily Ig kynurenine aminotransferase.
