The PEGS (Production and Environmental Generic Scheduler) program is a new generic scheduling program for manufacturing companies. It includes sort and search algorithms and can operate on the basis of elapsed time or economic values. Program performance is compared to a series of published benchmarks. The case study presented here illustrates the use of PEGS for a flow shop configuration at a ...

introduction: much of activities in today's world are based on information and less time is dedicated to gain experience and knowledge. therefore, different organizations compete based on their knowledge. in such a situation, knowledge management provides necessary tools to improve the performance of human resources and creates competitive advantages. this paper sought to determine the relation...

This paper describes the design of a programmable stay-alone continuous radon monitoring system able to detect, count and store the amount of alpha particles with an energy of 5.49 MeV produced by the radioactive decay of environmental radon-222. It is included the electronic circuit design, the software development as well as the user interface and the hardware ensemble of all the system compo...

The recent patents on corrosion resistant coatings were reviewed in this paper. The materials of corrosion resistant components, e.g., metals and alloys, ceramics, polymers as well as composite materials, developed for environmental, economic and other concerns were discussed. In addition, the novel methods for forming the coatings, including the powder floating by vibration and the precursor g...

in order to investigate the competitive effects of wild mustard on yield and yield components of wheat cultivars, field experiments was conducted in gorgan reaserch station during 2010-2012 growing seasons. the experiments were laid out in four replicated, factorial arranged rcb design. factors of the experiments included five different densities of wild mustard (0, 4, 8, 16 and 32 plants.m-2) ...

Abstract Large mammals at northern latitudes show annual cycles of body mass gain in summer and loss winter. The amplitude seasonal timing these may vary through ontogeny depending on trade‐offs toward investments structural growth versus fat storage, reproduction, future survival. Despite this knowledge, there is no detailed model how the seasonality develops ontogeny. Here, we define a new th...

this paper utilises the modified folchi method to assess the environmental impact of coal washing plant, alborz sharghi, north-east iran. in this study, the number of factors designed in the method was slightly modified by focusing on the environmental impact of coal washing operations. in addition, few other factors were designed and added to the previous factors. then, twenty-one values of en...

To study the flame propagation characteristics of coal dust explosion, principal component analysis and BP neural network are used to predict farthest distance maximum speed propagation. Among eight influencing factors characteristics, three components extracted named “the factor volatility,” intermediate diameter,” environmental temperature.” By using network, it is found that minimum predicti...
