This paper deals with adjustment of certain optical parameters of nano and micro-structured particles of silica by which Mastersizer 2000 as a device for size distribution particle measurement has been used. The optical method process may be used by looking for unique refractive and absorption index of investigated particles. Optical properties, i.e. refractive index and absorption index of the silica have been found and related to inter-particle silica bindings in the form of Hamaker constants2. For the optical properties calculations using the Mastersizer 2000 Mie Scattering solutions representing the electric and magnetic induction, i.e. silica's permeability and permittivity from Maxwell's equations have been exercised.
With the development of computers and software products, there is now greater use of quantitative methods in industrial enterprises when making managerial decisions. One of the most applicable solutions to computer simulation algorithms is the Monte Carlo method. The application of the Monte Carlo algorithm lies in finding a relation between the individual variables, which are the solutions to the problem and represent the characteristics of random processes reproducible on computers. The aim of this article is to show the application of simulations from the Monte Carlo algorithm using the example of optimising vehicle fleet capacity so that the total daily costs spent on transporting goods are minimal.
Electronic information transfer has existed for decades, and the many advantages of this type of communication are employed by large companies where quick, flawless and secure data transfer is essential. Many companies use advanced information systems internally, hence most of their documents are created in electronic format. It could therefore be said that for companies to exchange documents in hardcopy or via email and manually file these documents is an anachronism. If a company decides to take advantage of more modern data transfer technology, this is often more a necessity rather than a competitive advantage if the enterprise wants to remain relevant to key customers or suppliers.The aim of the article was to identify the suppliers and customers who would be ideal to implement joint EDI communications with, predict the efficiency and speed of purchasing and sales processes, recommend the broader use of EDI communication integration, evaluate the advantages and disadvantages of implementing EDI, and subsequently propose a suitable EDI cloud solution to integrate with the information system at a metallurgical enterprise.
Lack of qualified human resources has, for several years now, been the biggest constraint on the development of Czech industry, particularly in manufacturing facilities where working conditions are difficult. This category includes foundries. Therefore, these production facilities began addressing this problem through more intensive adaptation and in-house training of unskilled job seekers. The article presents the results of verifying the implementation of situational leadership tools in practice at a foundry and their impact on the development of employee work independence for a period of 4 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
