WEDM process is used extensively where the conventional machining process shows their limitations. Wire Electrical Discharge Machining is used to manufacture geometrically intricate shapes with higher accuracy and better surface finish. In the present study, the performance parameters i.e. cutting speed and surface roughness were investigated. The experiments were conducted under the constant c...

In this paper we develop a new semantics for disjunctive logic programs, called Well-Founded Semantics with Disjunction (WFSd), by resorting to a fixed point-based operator. Coinciding with the WellFounded Semantics (WFS) for normal logic programs, our semantics is uniquely defined for every disjunctive logic program. By exploring examples, we show WFSd does not agree with any other semantics w...

Zinc is a trace element and plays a vital role in all physiological processes in humans. It has been introduced as a drug in the prevention and treatments of diseases since last two decades. The Ayurvedic physicians have practiced both oral and topical applications of zinc after sodhana (purification) and marana (calcification) before 14 century A.D. Rasaka or Kharpara (zinc ore or zinc carbona...

This paper builds on initial evidence of First Language influence on brass playing presented in Heyne and Derrick (2013) [13] by indicating how tongue positioning might affect trombone timbre. Ultrasound imaging of the tongue was used to compare vowel production and sustained trombone notes for three participants, one each of New Zealand English, Tongan and Japanese, whose musical production wa...

In brass instruments the player’s lips are used as a control valve that allows an oscillating flow of air into the instrument. The behaviour of this valve, the lip-reed, is determined by both the pressure difference across the lips and the open area between the lips. Computer simulations of brass instrument playing frequently represent the lips as an oscillating system with one degree of freedo...

Real Applications of Databases ask for the support of Ag-gregation. This, however, needs stronger semantics than usual. In particular , such semantics should extend the wellfounded semantics WFS. We study such extensions and determine which semantics are possible given certain abstract properties like partial evaluation, cumulativity, partial monotony and supraclassicality. While WFS + (introdu...

Machining of medium Brass alloy is very difficult. There are a number of parameters like cutting speed, feed and depth of cut etc. which must be given consideration during the machining of medium Brass alloy. This study investigates the effects of process parameters on Material Removal Rate (MRR) in turning of C34000. The single response optimization problems i.e. optimization of MRR is solved ...

Deformation microstructure and texture in a cold-rolled austenitic steel 310S with low stacking fault energy (SFE) have been investigated by SEM and TEM. When 310S plates were rolled by 95% in thickness reduction, a remarkable development of the brass-type preferred orientation was confirmed by X-ray diffraction. SEM observations of the specimens with such texture exhibited a layered structure ...

We describe a design for the modular horizontal activity disc and tandem cages suitable for continuous monitoring of spontaneous running and of core temperatures in golden hamsters. An acrylic disc is equipped with a short brass axle. It is mounted inside a brass rotation sleeve at a 15 degrees angle off the horizontal plane. The disc module fits firmly inside either half of the tandem cage whe...

Taking into account the use of Nickel brasses in industry a great number of methods for the determination of Ni have been reported. More, theoretical predictions of free Cd increasing with decreasing salinity have been confirmed using cadmium selective electrodes. The method under proposal, for the determination of nickel ions in brass alloys consists of the following steps: Cu masking with sod...
