A New Method of Velocity Estimation Based on Variable Temporal Basis Using Incremental Encoder

1997

Abstract This paper deals with analysis and synthesis of algorithms for digital conditioning of signals generated by incremental encoders to estimate velocity of rotating devices for control purposes. Main objectives are to obtain high accuracy at low and high velocity and low tracking delays during accelerations. A digital conditioning method is described, Which uses a polynomial of order n whose coefficients are updated so as to fit the n+1 most recent velocity data acquired on a variable temporal basis. Digital sinlulations and experimental findings are shown with the ainl to validate the proposed estimation method and compare it with other methods.

[Validity of the use of penbutolol in essential arterial hypertension].

1990

Thirty patients suffering from WHO I-II class slight-moderate essential arterial hypertension were treated with a beta-blocker (Penbutolol) alone and once a day to assess its antihypertensive effectiveness and its affect on heart frequency, lipid metabolism and kidney function. The drug proved highly effective in reducing P.A.S. and P.A.D. values and no negative influence was documented on lipid metabolism, kidney function or heart frequency.

[Cardiovascular response to sympathetic stimulation in normal subjects with or without familial hypertension].

1990

The aim of our study was to seek out a possible different reactiveness to cardiovascular stimulation tests among normotensives with and without positive family history of essential hypertension. We have studied about 200 inhabitants of Ustica and 49 medicine students, all normotensives according to the World Health Organization and the Joint National Committee criteria. In an isolated room and in a supine position, blood pressure (BP) and heart rate were measured every 30 s for 15 min with an automatic sphygmomanometer. Averages of last 4 measurements were considered baseline values. Then we have carried out mental stress (MS), handgrip and active orthostatism test (AO) in the inhabitants o…

Microproteinuria as an index of initial renal lesion in patients with rheumatoid arthritis.

1990

Our investigation included 20 patients with rheumatoid arthritis and a negative routine (albustix) proteinuria test, and 20 healthy controls. The albustix test was compared with a method based on multifractional Cellogel RS electrophoresis of urinary proteins. The albustix test was found to be not reliable in patients with RA. Microproteinuria was in fact detected by the electrophoresis method in 12 out of 20 RA patients. Eleven patients showed glomerular type proteinuria (which was "selective" in 5 patients and "non-selective" in 6 patients), and 1 patient showed mixed type proteinuria. Electrophoresis failed to show microproteinuria in the controls. The high sensitivity, easy handling and…
