Oct 31, 2008nbsp018332manufacturing lenses. Many optical engineers will only ever work with a finished product, or even software that models a finished product, but it is important to understand the process of how a lens is made. Knowledge of the manufacturing process will allow an engineer to understand the limitations of an optical design with regards to a timeline,

What is data mining it is a process of extracting useful information or knowledge from a tremendous amount of data or big data. the gap between data and information has been reduced by using various data mining tools. it can also be referred as knowledge discovery from data or kdd.
This process is important because of data mining learns and discovers from the accessible data. this is the evidence base for building the models. if some significant attributes are missing, at that point, then the entire study may be unsuccessful from this respect, the more attributes are considered.
Mining amp mineral processing 7 mining amp mineral processing filter press vacuum or press filters are an essential step in the mining process to separate water from the minerals. this is mostly done mechanically, although thermal drying can be used. the transportation of the

Mechanized mining technical process mmtp related to the control method of the shearer is a vital process in thin coal seam mining operations. an appropriate mmtp is closely related to safety, productivity, labour intensity, and efficiency. hence, the evaluation of alternative mmtp is an important part of the mining design. several parameters should be considered in mmtp evaluation, so the ...
Text mining is an interdisciplinary field that draws on information retrieval, data mining, machine learning, statistics, and computational linguistics. a substantial portion of information is stored as text such as news articles, technical papers, books, digital libraries, email messages, blogs, and web pages.
Uranium mining methods. based on the current understanding of uranium deposits in the commonwealth of virginia, extraction of uranium ore would use open-pit mining, or underground mining, or a combination of both .these general terms incorporate a large variety of design possibilitiesthere are as many methods of mining uranium as there are orebody sizes, shapes, and mineral constituents.
Process outline the components of the deposition process, from performance requirement to finished product, are diagrammed in figure 1. it is evident from the descriptions of the process components that material science and deposition technology play complex interdependent roles in successfully producing optical coatings.
Attribute selection in this strategy, new attributes are constructed from the given set of attributes to help the mining process. discretization this is done to replace the raw values of numeric attribute by interval levels or conceptual levels. concept hierarchy generation
Fig.1 indicates effective parameters in selection fleet types 2. expert system this is one of the first systems planned for selecting equipments in surface mining in 1987. in the proposed project, the main reasons described for using the expert system were the intense need of equipment selection process, past expertise, experiences and
Mar 02, 2016nbsp018332the new process was piloted with three potential new suppliers. the analysis of the pilot cases indicated that the process could benefit from a wider set of sourcing requirements or criteria that would be followed throughout the whole process from the initiation of the new supplier selection process to the analysis and finally the selection of
