This paper proposes a generic feature geometry based lexical representation of phonological description using inheritance networks which has applications in various areas of speech technology. The feature geometry based lexicon model provides the linguistic knowledge for a generic lexicon tool which allows application-specific lexica to be generated. The relevance of this approach to interactiv...

Interactive geometry software is established as an important tool in geometry and math education. We present our research on possible ways to use such software in wireless classroom environments. In particular, we address user interface issues on portable devices and describe how we maintain a common code base for both desktop and mobile environments, thus increasing the stability of the applic...

We give a general and nontechnical review of some aspects of non-commutative geometry as a tool to understand the structure of space-time. We discuss the motivations for the constructions of a noncom-mutative geometry, and the passage from commutative to noncommu-tative spaces. We then give a brief description of Connes approach to the standard model, of the noncommutative geometry of strings a...

This chapter gives a cursory introduction to the field of Turtle geometry. Developed as part of a programming language, Turtle geometry is used as both an instrument to teach math to children and as a tool for generating pictures using grammars. It is the latter which will be the topic of this chapter. Two definitions of Turtle geometry will be given, as well as an example to illustrate the use...

A judicious choice of insert material, tool geometry and cutting conditions can make hard turning produce better surfaces than grinding. In the present study, an attempt has been made to investigate the effect of cutting tool materials on cutting forces (feed force, thrust force and cutting force) in finish hard turning of AISI D2 cold work tool steel. In conclusion of the results obtained with...

this paper presents the findings of experimental investigations into the effects of cutting speed, feed rate, depth of cut and approach angle on the machinability of titanium (grade-5) alloy. also the comparison for the two different cutting materials inserts polycrystalline diamond (pcd) and cubic boron nitride (cbn) with similar tool geometry for similar machining parameters is also carried o...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

All process elements of a reconfigurable manufacturing system should accommodate future changes. This paper looks at one such process element, tool paths, with focus on face milling and pocket milling. Tool paths for the first part are designed to optimize the process outcomes for the initial constraints. Change in market conditions or part design leading to change in cycle time requirements, g...

This paper describes Discover, a program for learning and teaching geometry with the help of a computer. The program is a dynamic geometry environment that can communicate with Mathematica, using its symbolic capabilities to perform geometric discovery or rediscovery. Discover is specially suited to be used as a learning tool for geometry from the ages of 12 up to University. It permits the rep...

Considering a Hamiltonian Dynamical System describing the motion of charged particle in a Tokamak or a Stellarator, we build a change of coordinates to reduce its dimension. This change of coordinates is in fact an intricate succession of mappings that are built using Hyperbolic Partial Differential Equations, Differential Geometry, Hamiltonian Dynamical System Theory and Symplectic Geometry, L...
