In the world of software systems, the process of evolving is an essential one. If this process represents no challenge on small systems, it becomes unbearable if the size of the system exceeds a certain limit. Therefore, the need arises for software tools that can carry out the necessary transformations automatically. This paper addresses the possibility to detect spots within an object-oriente...

Factory farming continues to grow around the world as a low-cost way of producing animal products for human consumption. However, many of the practices associated with intensive animal farming have been criticized by public health professionals and animal welfare advocates. The aim of this essay is to raise three independent moral concerns with factory farming, and to explain why the practices ...

Welding is a major industrial process used for joining metals. Occupational exposure to welding fumes is a serious occupational health problem all over the world. The degree of risk to welder's health from fumes depends on composition, concentration, and the length of exposure. The aim of this study was to investigate workers' welding fume exposure levels in some industries in Jeddah, Saudi Ara...

The Virtual Factory is a job shop scheduling tool that was developed at NC State. It has been found to provide nearoptimal solutions to industrial-sized problems in seconds. Recently, the Virtual Factory was expanded to include interfactory transportation operations which enabled the detailed scheduling of entire multi-factory manufacturing supply chains. Separately, a rolling horizon procedure...

Control/command processes require a transmission system with some characteristics like high reliability, low latency and strong guarantees on messages delivery. Concerning wire networks, field buses technologies like FIP offer this kind of service (periodic tasks, real time constraints...). Unfortunately, few wireless technologies can propose a communication system which respects such constrain...

ions and Presentations. The PAC-C3D factory will give each Control one factory for Abstraction creation, and a list (which can be empty) of factories for Presentations creation, corresponding to each kind of existing Presentation on its node. If allowed by its distribution policy, then the Control will ask the Abstraction factory to create a real Abstraction. Next, the Control will ask each Pre...
