Quality and productivity are two important aspects that are inter-related in any machining operation The objective of this work is to estimate the influence of machining parameters and to determine their optimum conditions in manufacture of cast-iron disintegrated flywheel. The parameters considered are speed, feed and depth of cut where as the response are material removal rate and surface rou...

In this paper, we present a new string pattern matching-based passage ranking algorithm for extending traditional textbased QA toward videoQA. Users interact with our videoQA system through natural language questions, while our system returns passage fragments with corresponding video clips as answers. We collect 75.6 hours videos and 253 Chinese questions for evaluation. The experimental resul...

Electric Discharge Machining (EDM) is one of the machining process, which is used to produce critical shape on any type of hard or brittle conductive material and it can also be well applied for materials that are impossible to machine with traditional machining processes. The present work mainly demonstrates the optimisation process of multiple responses i. e. MRR, TWR and OC of EDM by using g...

The wire electrical discharge machining (WEDM) experiments has been conducted using air and water mixture as a dielectric medium, is called environmental friendly near dry WEDM. In this technology, the dielectric fluid (Deionized water) is replaced by liquid-air to minimize the environmental impact in the machining zone and operator health. The effect of discharge current (I), Pulse width (TON)...

This year’s TREC 2003 web task incorporated two retrieval tasks into a single set of experiments for Known-Item retrieval. We hypothesized that not all retrieval tasks should use the same retrieval approach when a single search entry point is used. We applied task classifiers on top of traditional web retrieval approaches. Our traditional retrieval is based on fusion of result sets generated by...

This paper presents a review on the problems encountered in machining titanium and application of USM in machining titanium and its alloys. Experiments have been conducted to assess the effect of three factors-tool material, grit size of the abrasive slurry and power rating of ultrasonic machine on machining characteristics of titanium (ASTM Grade I) using full factorial approach for design and...

In this paper we are reporting the results obtained after submitting one run to the Mixed Monolingual task of WebCLEF 2006. We have used a text reduction process based on the selection of mid-frequency terms. Although our approach enhances precision, it must be improved in recall by an enrichment process based on the addition of high co-ocurrence terms. We have seen that a improvement of 40% in...

We developed an open domain QA system that can handle factoid and nonfactoid questions in Indonesian language by using monolingual approaches. EAT classification is done by identifying question word and clue words. Keyword extraction from question is done by looking at POS information of each word in question, eliminating stop words, and stemming. We use articles from Indonesian Wikipedia as co...

This paper discusses the linguistic module of an Ontology Natural Language Interaction System that is based on semantic restrictions. The system, called ONLI, takes as input questions in unrestricted natural language, translates them into nRQL, an extension to the RACER ontology query language, then generates answers as returned by the RACER ontology reasoning server. Translation into nRQL is d...

Multi-objective optimization Genetic Algorithms Robust Design The following paper describes the main objective to follow the methodology used and proposed to obtain the optimal values of WEDM process operation on the machine Robofil 310 by robust parameter design (RPD) of Dr. G. Taguichi [TAGUCHI, G. 1993], through controllable factors which result in more inferences regarding the problem to no...
