The mathematical models used to compute the materials balance a t the various stations in a sugar factory are described and the overall logic of , the computer program to prepare a factory materials balance is discussed. The use of the program to study the effect on the factory of varying one process parameter is illustrated and other applications of the program are discussed.

OBJECTIVES After a plastic reprocessing factory began to operate in August 2004, the residents around the factory in Neyagawa, Osaka, Japan, began to complain of symptoms. Therefore, we conducted an exposure assessment and a population-based epidemiological study in 2006. METHODS To assess exposure, volatile organic compounds (VOCs) and total VOCs were measured at two locations in the vicinit...

The production of textile materials has undergone dramatic changes in the last century. Man-made cellulose fibres have played an important role for more than 70 years. Today, the man-made cellulose fibre industry is the worldwide second largest biorefinery (next to the paper industry). In the last few years, the interest in man-made cellulose fibres has grown as a consequence of increased envir...

Markets are becoming increasingly dynamical and unpredictable. Trends such as the shortening of the product life cycle, individualization of customer requirements and globalization, which includes an adaptation to international markets and standards, can be observed. In result, demands for adaptable factory systems are increasingly addressed towards industrial engineering. The department of Fac...

The IT landscape of telecommunications companies is far more dynamic than IT landscapes in most other application domains. The main reason for this is the fast development of new technologies that form the basis of new telecommunications products. These products very often require new or adapted technological devices as well as IT processes for production, operation and assurance of new or exis...

Factory is an extension of Java which provides a template-based reflection mechanism for generative programming. Java classes can be parameterized by types, and the structure of the classes can be described dependent on these type parameters. Factory can address a wide range of applications and save programmers a lot of work. It is designed to integrate seamlessly with Java, to be intuitive for...

No doubt, user experience (UX) has become of high relevance within the HCI community. Within this paper, we present initial results from a qualitative study on UX in the factory context, more precisely in a semiconductor factory. We highlight the challenges of performing UX research in this particular context and the usefulness of probes for collecting feedback from operators in the factory con...

Operational-level scheduling decisions on the factory floor include the release policy and the dispatching rule. Recent work by researchers suggests that factory performance depends heavily on the release policy. Several heuristic factory release rules have been developed that generate release decisions based on the status of the bottleneck machine. The heuristic rules perform very well in redu...

Plant factory is known as the closed controlled plant production systems with the artificial lighting. Environmental factors have been concerned as the most important factors to influence quality of product in plant factory. One of the most applicable technologies for optimizing plant production system in plant factory is Infotronics. In the plant factory, Infotronics is defined as a combinatio...

BACKGROUND Microscopic fungi are the biological agent of occupational risk in the woodworking environment. Microbiological and chemical methods were used for determination of their concentration and species composition in dust. MATERIAL AND METHODS Dust was sampled in 3 factories producing furniture using different materials. The 1st factory (A) processes solid wood, the 2nd (B) - chipboards ...
