The amount of geometric information that must be transferred between a CAD system and a computerized numerical control system creates a conflict between part precision on the one hand and feedrate fidelity and communications load on the other. This is the motivation for the development of new curve interpolation algorithms for CNC. The interpolation dependson the method of curve representation,...

In the past few decades, Computer Aided Design (CAD) systems have evolved from 2D tools that assist in construction design to the basis of software systems for a variety of applications, such as (re)design, manufacturing, quality control, and facility management. The basic functions of a modern CAD system are storage and retrieval of 3D data, their construction, manipulation, and visualisation....

Background: Coronary artery diseases (CAD) is the most common cause of death in the developing counteries.  Atherosclerosis is the leading cause of CAD. A number of studies have shown that total leukocyte count is a risk factor for CAD but there is little information on the role of eosinophilia and allergy.  The aim of this study was to determine the relationship between eosinophilia and histor...

A CAD environment requires a significantly different model of transaction from that developed for typical data-processing applications. A viable model of CAD transaction must allow a group of cooperating designers to arrive at a design without being forced to wait over a long duration. It must also allow a group of designers to collaborate on a design with another group by assigning subtasks. I...

To enable the designers to design and modify model of nuclear channel head quickly and easily, we constructed the CAD system of the nuclear channel head. At first, we analyzed the geometric characteristics of nuclear channel, established of feature control parameter set and the parametric model of nuclear channel head. Secondly, other parameters related to the solid modeling are described throu...

This study conceptualizes, operationalises and validates the concept of Knowledge Management Competence as a four-phase multidimensional formative index. Employing survey data from 310 respondents representing 27 organizations using the SAP Enterprise System Financial module, the study results demonstrate a large, significant, positive relationship between Knowledge Management Competence and En...

south asian countries have a high prevalence of coronary heart disease (cad) in line with their economic development. in these countries, we find nearly one quarter of the total world population in the process of nutritional transition, from poverty to affluence due to rapid economic development. india; in particular, with a population of over one billion has a high burden of cad. to evaluate t...
