Pronominal Anaphora Resolution Using XML Tagged Documents

Anaphora resolution has become a major issue in natural language processing systems; in this work we propose a resolution approach in which texts are parsed by a definite clause grammar and then converted into an XML-tagged representation, where sentence elements are marked with discourse, syntactic, and semantic attributes. This extension was made primarily to test the viability of using XML tagged documents for anaphora resolution. The XML representation allows valuable text’s enrichment with anaphoric information in an elegant and easy way. The system’s performance arises primarily from the integration of multiple knowledge sources in a modular architecture and uses constraints and preferences to select the antecedent. The developed system proposes to resolve pronominal anaphora, namely personal pronouns for French language texts.

A Decision Support System for Process Planning and Control of Polyurethane Foam Production

Major sections involved in the production of Polyurethane foam are: Chemical reactions, raw material formulations, heat transfer during curing stage, and the temperature conditioning of the chemicals, and these are the major problems in the optimal production of Polyurethane foam. A Polyurethane foam industry in, was used as the case study for this research work. Data for process planning, manufacturing, and cost of polyurethane foam were collected, complimented by extensive literature survey carried out both from the library and through direct interview from domain expert. The data collected were used to model polyurethane foam process planning, raw material combination formulation, and manufacturing cost computation. A comprehensive flow chart for process planning and cost estimation of polyurethane foam was designed. This was used to develop a decision support system (DSS) for process planning and control of Polyurethane Foam production.

Control of Greenhouse Climatic Condition Using Wireless Sensor Networks

Greenhouses provide a good environment for the growth of the plants. The use of greenhouses with controlled microclimate according to the plants need is an important way to increase the plant production. Cabling techniques which used to measure the climatic condition in a greenhouse needs many wires and power sources which makes the system expensive and vulnerable to failure. In order to overcome the drawbacks of cabling techniques, smart sensing nodes with wireless capability is used to efficiently monitor the climatic condition in a greenhouse. The data from the sensor nodes are sent to a wireless gateway connected to a computer that is used provide commands to operate the relays for maintaining the necessary temperature in accordance to the crop. The system proposed in this paper collects data such as temperature, relative humidity, light intensity and soil moisture, as these parameters are important for the plant growth. The factors that are controlled are ventilation fan, light and water sprinkler. The main advantage of the proposed approach in comparison with the previous work is the reduction in the use of wires and the system is implemented using low power wireless components which are easier to install.

Transient Stability Assessment of Multi-Machine Power System Using Swallowtail Catastrophe Theory

Now a day’s transient stability study constitute the major analytical approach to the study of power system electromechanical dynamic behavior. Transient stability study of a power system is required to determine whether the system will remain stable or not after major disturbances such as sudden load changes (induction motors starting), loss of generating units, transmission system faults or line switching. The degree of the system stability is an important factor in the planning of new facilities and interconnection. In this study, a method for online Transient Stability Assessment (TSA) of large scale power systems is proposed.The method namely catastrophe theory is used to determine the transient stability regions. Taylor series expansion is used to find the energy balance equation in terms of clearing time and system transient parameters. The energy function is then put in the form of swallowtail catastrophe manifold from which the bifurcation set is extracted. The bifurcation set represents the transient stability region in terms of the power system transient parameters bounded by the transient stability limits. The transient stability regions determined are valid for any changes in loading conditions and fault location.

Multi-form, Multi-format Digital Comparator

In this paper we analytically prove the possibility for synthesis of multi-form, multi-format digital comparator based on the unsigned comparison algorithm of binary numbers. The synthesized comparator is a new unique logical circuit, which is capable of comparing signed binary integers and binary fractions as well as binary-coded decimal numbers. This circuit is also capable of comparing floating-point numbers as represented in the IEEE-754 standard. The comparator is highly applicable since it integrates many different ways of representing the compared numbers by using this algorithm. It can successfully replace the traditional algorithm for comparison based on subtraction, which is used in digital processors. The comparator latency has been explored because it is necessary when the comparator is used in asynchronous control systems. The law of the latency distribution and its parameters has been defined.
