This paper synthesizes confirmation by instances and confirmation by successful predictions, and thereby the Hempelian and the hypotheticodeductive traditions in confirmation theory. Our merger of these two approaches solves classical problems such as the tacking paradoxes and the raven paradox and is subsequently extended to the piecemeal confirmation of entire theories. We compare our proposa...

A number of research studies has shown that faults in a stator or rotor generally show sideband frequencies around the mains frequency (50 Hz) and at higher harmonics in the spectrum of the Motor Current Signature Analysis (MCSA). However in the present experimental studies such observations have not been seen, but any fault either in the stator or the rotor may distort the sinusoidal response ...

Accurate descriptions of organ motion due to breathing are highly desirable for radiation treatment planning. This paper proposes an index that quantifies the irregularity of a signal related to respiratory motion. The method works by finding the periodic band-limited signal that best fits the signal samples, and then computing the root mean squared (RMS) residual error. The fitted signal itsel...

A comparison was made of the performance of swing-out and vertical ultracentrifuge rotors in the detection of rubella-specific IgM on a sucrose density gradient. Tests were performed on 30 sera, of which 11 were found to contain rubella-specific IgM by both methods. The centrifugation time for the swing-out rotor was 16 hours at 35,000 rpm. This was reduced to 2 hours using the vertical rotor a...

PURPOSE The aim of this investigation was to evaluate the preferred cycling cadence of professional riders during competition. METHODS We measured the cadence of seven professional cyclists (28 +/- 1 yr) during 3-wk road races (Giro d'Italia, Tour de France, and Vuelta a España) involving three main competition requirements: uphill cycling (high mountain passes of approximately 15 km, or HM);...

Background: Joint contracture is a limitation in the passive or active range of motion (ROM) of a joint, where in addition to the mobility limiting factor the pain is also present. Repetitive pulsed Magnetic Stimulation (rPMS) appears to be an effective, non-invasive and safety solution for treating this condition. Therefore aim of this study was to evaluate the effect of rPMS in treating joint...

In a pilot study, affective components of pain were assessed using repetitive peripheral magnetic stimulation (rPMS) in patients with borderline personality disorder and healthy controls. Significant differences in pain thresholds and in affective components of pain between both groups were found. rPMS was well tolerated and suitable for assessing pain.
