Suicide in Prisons: Active Deviation Profile [PDF]

International Journal of Scientific and Research Publications (IJSRP), 2020
The interpretative path of suicide finds its maximum expression in the theorizations of Èmile Durkheim who classifies suicide as a social pathology and as a result of a general social fragility. The more generic theme of "deaths" in prison began to arouse the interest of scholars around the mid-19th century, a period in which "suicide death" was ...

Examination of teaching data for Hobbing-Machine-Diagnosis system (Comparison of classification performance of helical gears and spur gears and comparison of matrix images by hobbing simulation and actual hobbing)

Nihon Kikai Gakkai ronbunshu, 2022
Various factors in hobbing processes affect profile and helix deviations of hobbed gears, which prevent problems on the hobbing machine from being analyzed using them. Identifying problems requires a system that allows itself to evaluate motion errors in

Expression of gear-tooth-flank deviations for Hobbing-Machine-Diagnosis system (Learning-data collection through hobbing simulation and their compression with network representation)

Nihon Kikai Gakkai ronbunshu, 2021
A hobbed gear has pitch, profile, and helix deviations caused by various factors. However it is hard for even experts to specify which factors cause individual deviations from the measured ones. Therefore, a hobbing-machine-diagnosis system could play a

Study on the skiving process of an internal gear (Effects of axial feed rate on gear accuracy)

Nihon Kikai Gakkai ronbunshu, 2015
In this paper, study on the effects of axial feed rate on the gear accuracy is discussed. First, geometrical model of a skiving process was introduced. The model was assumed that the cutter was perfectly made and perfectly assembled to the skiving rig (i.
