The characteristics of a cavitation water tunnel test setup and the experiments of cavitation around different models are given in this paper. Models of test are formed from combination of head and variable length afterbody. The experiments are performed initially with the smooth head and then with the roughened head. Cavitation initiates both in the wake and after the head. If the nose of mode...

The goal of paper is to present the magnetic field calculations in high current bus ducts. Finiteelement method is used to do this. Bus ducts under study have figure such as circle area. Thecalculations will be using mathematical relations, meshed geometric shape and analyzing them.Geometric mean will help us to determine the value of magnetic field. COMSOL software is appliedfor simulation stu...

k-fold cross validation is a popular practical method to get a good estimate of the error rate of a learning algorithm. Here, the set of examples is first partitioned into k equal-sized folds. Each fold acts as a test set for evaluating the hypothesis learned on the other k − 1 folds. The average error across the k hypotheses is used as an estimate of the error rate. Although widely used, espec...

Cross-tabulation is one of the most useful analytical tools and is a main-stay of the market research industry. One estimate is that single variable frequency analysis and cross-tabulation analysis account for more than 90% of all research analyses. Cross-tabulation analysis, also known as contingency table analysis, is most often used to analyze categorical (nominal measurement scale) data. A ...

In this paper, the results of modeling and simulation a microcolumn are presented. The is part developed miniature MEMS electron microscope equipped with high-vacuum micropump. Such an arrangement makes device first stand-alone electron-optical to operate without external chamber. Before such can be fabricated, research on particular elements must carried out determine working principles device...

2014 We propose a theory to calculate the pressure gradient and the liquid fraction in two-phase gasliquid fully developed stratified flow in a cylindrical duct of arbitrary cross-section and slope and its application to near horizontal ducts. Its validity is limited to Reynolds numbers high enough to ensure turbulent flow in both phases. Droplet entrainment or bubble inclusion have not been ta...
