To assess the wear of hot stamping tool, a model punch deformation under influence thermal and mechanical loads was developed. The shape relative position die were designed to localize maximum contact at predetermined location. It assumed that is caused by removal surface metal layer, due decreasing its strength during plastic deformation. Simulation performed finite element method in Deform so...

a new dynamic friction model for modeling of elliptical vibration assisted turning (evat) was developed in this research. the periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. in modeling of machining processes (including the evat process), static coulomb friction model was employed by most of the researchers. because of the peri...

often in modeling the engineering optimization design problems, the value of objective function(s) is not clearly defined in terms of design variables. instead it is obtained by some numerical analysis such as fe structural analysis, fluid mechanic analysis, and thermodynamic analysis, etc. yet, the numerical analyses are considerably time consuming to obtain the final value of objective functi...

Minimality is an important optimization criterion for solutions of data exchange problems, well captured by the notion of the core. Though tractability of core computation has been proved, it has not yet become a part of any industrial-strength system, still being highly computationally expensive. In this demonstration, we show how core computation can be used in a data exchange modeling tool, ...

UNLABELLED Hidden Markov models (HMMs) are probabilistic models that are well adapted to many tasks in bioinformatics, for example, for predicting the occurrence of specific motifs in biological sequences. MAMOT is a command-line program for Unix-like operating systems, including MacOS X, that we developed to allow scientists to apply HMMs more easily in their research. One can define the archi...

The effect of a combination of lithotripter shock waves and cytotoxic drugs was examined in vitro. L1210 cells in suspension were exposed to shock waves during incubation with cisplatin, doxurubicin, daunorubicin, THP-doxorubicin, or aclacinomycin. Proliferation was determined using the 3-4,5 dimethyl-thiazol-2,5 diphenyl tetrazolium bromide assay. Dose enhancement ratios were calculated for ea...
