The iSLIP algorithm has been proved to be a very efficient, high throughput scheme for scheduling in input-queued switches. In this paper, we discuss a Modified Round Robin (MRR) scheme, which involves less number of arbitration steps in each iteration when compared to iSLIP. We prove through simulation studies, that the MRR algorithm shows a performance equivalent to iSLIP, but requires less n...

In this paper, we discuss our experience in using semantic constraints to improve the precision of a reformulation-based questionanswering system. First, we present a method for acquiring semanticbased reformulations automatically. The goal is to generate patterns from sentences retrieved from the Web based on syntactic and semantic constraints. Once these constraints have been defined, we pres...

In this paper, the cutting of Tungsten Carbide ceramic using electro-discharge machining (EDM) with a graphite electrode by using Taguchi methodology has been reported. The Taguchi method is used to formulate the experimental layout, to analyse the effect of each parameter on the machining characteristics, and to predict the optimal choice for each EDM parameter such as peak current, voltage, p...

The objective of this paper is to study the effect of the various process parameters i.e. peak current, noload voltage, pulse on time and duty cycle on response parameters by mixing silicon powder in the dielectric fluid of the Electric Discharge Machining (EDM). Response surface methodology (RSM) is used for investigating the effect on these parameters. Central composite design (CCD) is used f...

The nano surface roughness of metallic materials is important in engineering and medical fields for specific applications. Magneto rheological abrasive flow finishing (MRAFF) process was performed on nickel-free austenitic stainless workpieces order to obtain at the level also forecast performance MRAFF terms responses such as (SR) material removal rate (MRR). These two are affected by factors ...

Abstract This study focused to machine novel Nimonic 80A through Electric Discharge Machine process. The process parameters are optimised achieve high surface integrity along with material removal rate (MRR) minimum energy consumption. Central composite design analysis of variance technique has been applied make correlation between the parameter and responses. developed model roughness shows th...

Silicon photonic micro-ring resonators (MRR) developed on the silicon-on-insulator (SOI) platform, owing to their high sensitivity and small footprint, show great potential for many chemical biological sensing applications such as label-free detection in environmental monitoring, biomedical engineering, food analysis. In this tutorial, we provide theoretical background give design guidelines SO...

An experimental investigation was conducted to determine the application of die sinker electrical discharge machining (EDM) as it applies to a hybrid titanium thermoplastic composite laminate material. Holes were drilled using a die sinker EDM. The effects of peak current, pulse time, and percent on-time on machinability of hybrid titanium composite material were evaluated in terms of material ...

Recently, much interest is being taken in a method to protect the copyright of digital data and prevent illegal duplication of it. However, in the area of CAD/CAM and CG, there are no effective ways to protect the copyright of the 3D geometric models. As a first step to solve this problem, a new digital watermarking method for 3D polygonal models is introduced in this paper. Watermarking is one...

In NTCIR3 QAC1, we proposed a method to introduce an A search control into sentential matching mechanism for Japanese question answering systems, in order to reduce the turn-around time while keeping the accuracy of the answers. Using the method, we do not have to any preprocessing on a document database, and we may use any IR systems with writing a simple wrapper program. There however is a pr...
