Virtual touch screen using camera is an ordinary screen which uses a camera to imitate the touch screen by taking a picture of an indicator, e.g., finger, which is laid on the screen, converting the indicator tip position on the picture to the position on the screen, and moving the cursor on the screen to that position. In fact, the indicator is not laid on the screen directly, but it is interv...

this paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. different railways use different threshold radius from 91m to 365m to provide restraining rail. these threshold figures are probably experience driven choices. the need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

background: blood neutrophil to lymphocyte ratio (nlr) and mean platelet volume (mpv) both have been used as a simple marker of inflammation in many disorders. here, we aimed to investigate the relationship between nlr, mpv, and familial mediterranean fever (fmf). materials and methods: in this retrospective study, the fi les of fmf patients in pediatric rheumatology outpatient clinic were revi...

Current methods to evaluate the severity and progression of the disease, effectiveness of therapy and survival among cancer patients are generally limited in their prognostic ability. Whole-body phase angle, measured by using a tetrapolar, phase-sensitive bioelectrical impedance analyzer, offers a new approach. Phase angle (arc tangent of the ratio of reactance to resistance) is a non-invasive ...

In this manuscript, a new method is proposed to provide a perfect tracking of the supercavitation system based on a new two-state model. The tracking of the pitch rate and angle of attack for fin and cavitator input is of the aim. The pitch rate of the supercavitation with respect to fin angle is found as a non-minimum phase behavior. This effect reduces the speed of command pitch rate. Control...
