Charcot (1889) divided tremor into three categories: slow, intermediate, and vibratile. He included alcoholic tremor in the 'vibratile' category, i.e., it was of low amplitude as compared with Parkinsonian or hysterical tremor, and occurred at 8 to 9 c/sec. Friedlander (1956) detected tremor of the tip of the index finger by means of an electromagnetic technique. He compared the records obtaine...

− In this paper, improved sine-fitting algorithms for the measurement of amplitude and phase difference between two records of digitized sine waves with the same frequency are presented. These algorithms can be used for example in impedance measurements or to accurately measure the input and the output of a linear system to be characterized in the frequency domain both in amplitude and in phase.

We use a flux transport model to simulate the evolution of the Sun’s total and open magnetic flux over the last 26 solar cycles (1713–1996). Polar field reversals are maintained by varying the meridional flow speed between 11 and 20 m s , with the poleward-directed surface flow being slower during low-amplitude cycles. If the strengths of the active regions are fixed but their numbers are taken...

background: the use of organophosphates (ops) in developing countries is rising in large quantities and non-secure methods. this problem not only causes acute poisoning but also may lead to chronic diseases such as polyneuropathy. in iran, 60% of pesticides are organophosphate compounds that may lead to delayed polyneuropathy. objectives: the purpose of the current study was to evaluate delayed...

Central to the debate surrounding global climate change and Plio-Pleistocene hominin evolution is the degree to which orbital-scale climate patterns influence low-latitude continental ecosystems and how these influences can be distinguished from regional volcano-tectonic events and local environmental effects. The Pliocene Hadar Formation of Ethiopia preserves a record of hominin paleoenvironme...

[1] Electronic sensors generate valuable streams of forcing and validation data for hydrologic models but are often subject to noise which must be removed as part of model input and testing database development. We developed an automated precipitation correction program (APCP) for weighing bucket precipitation gauge records, which are subject to several types of mechanical and electronic noise ...

In this paper, computer simulation of a three-phase synchronous motor drive is described. This drive/system is supplied with a new type of pulse-width modulated voltage source inverter (PWM VSI) whose amplitude of the first harmonic, compared to a conventional sinusoidal PWM VSI, is increased by about 17% and whose amplitude of higher harmonics is also reduced inversely proportional to their or...
