• Operating speed is used to check road design and posted limits consistency. Usually, the 85° percentile of operating (V 85 ) considered as crucial. V estimated a function functional features. New parameters are included estimate , compared past literature. Considering Province Brescia (Italy), two models calibrated tested. Vehicle crucial factor for safety, it strictly affects occurrence seve...

In this paper, a modified auto zeroed integrator is used to design and simulate a low-voltage high-Q switched capacitor pseudo 2-path filter.  The filter is a sixth–order Chebyshev band-pass filter operating at sampling frequency of 1MHz and center frequency of 250 kHz with a quality factor of 50. The proposed filter has both low-voltage and high speed properties of the auto zeroed integrators ...

To assist in the on-going effort to reduce road fatalities as much as possible, this paper presents a new methodology to evaluate road safety in both the design and redesign stages of two-lane rural highways. This methodology is based on the analysis of road geometric design consistency, a value which will be a surrogate measure of the safety level of the two-lane rural road segment. The consis...

The present work examines leaching of lipoxygenase-1 from soybean flour employing stirred tank vessel. The effect of operating parameters, impellers speed, operational period, temperature, pH and scale-up were considered.The acetic acid pH: 5.2 increased the leaching of lipoxygenase- 1.The sensitivity of agitator speed and geometrical-scale-up on the enzymeleaching has bee...

Noise generated by railway wagons in operation is produced large numbers of noise sources. Although the transport considered to be environmental friendly, especially production CO2 emissions, one problems that should solved keep competitive and sustainable future. In EU, there a strong permanent legislation pressure on interior exterior reduction transport. last years Slovakia, besides moderniz...
