for many physical systems like vehicles, acceleration can be easily measured for the respective states. however, the outputs are usually affected by stochastic noise disturbance. the mentioned systems are often sensitive to noise and structural uncertainties. furthermore, it is very difficult to estimate the multiple integrals of the signal, acceleration to velocity and velocity to position. in...

Performance of the conventional narrowband active noise control (NANC) system may degrade severely when the uncorrelated narrowband disturbance noise is present in the system. In this paper, we propose a new hybrid NANC system capable of reducing the primary noise and the uncorrelated disturbance simultaneously. First, some simple analysis is used to show why the NANC system may indicate poor p...

In the present study, the economic value of sleep disturbance due to traffic noise was examined by means of the contingent valuation method (CVM). In 2009, we conducted a questionnaire study in an area in Urayasu, Chiba, Japan; residents of this area are expected to be affected by the expansion of the Tokyo International Airport, which is scheduled for 2010. Residents were asked about their wil...

this paper deals with a globally convergent adaptive and sliding mode control of a cart-pole inverted pendulum for trajectory tracking in the presence of a bounded measurement noise and parameter uncertainty. two kinds of controllers have been used for evaluation of tracking error in presence of a bounded noise; as a result, we want to compare that at what time we can see the convergence of tra...

Heisenberg’s uncertainty relation for measurement noise and disturbance states that any position measurement with noise ǫ brings the momentum disturbance not less than h̄/2ǫ. This relation holds only for restricted class of measuring apparatuses. Here, Heisenberg’s uncertainty relation is generalized to a relation that holds for all the possible quantum measurements, from which conditions are ob...
