Fiber optical gyroscopes (FOGs) have been applied widely in navigation for mobile robots. The precision of outputs from FOGs is affected significantly by uncertain disturbances due to road conditions in practice. It is urgent to eliminate uncertain disturbances from outputs of sensors in harsh environments. This paper proposes an adaptive method of signal processing base on wavelet and fuzzy lo...

Owing to the various sources of complexity in electrical power system, such as integrating intermittent renewable energy resources and widely spread nonlinear system components, which result sudden changes operating conditions, conventional PID controller fails track dynamic challenges mitigate frequency deviation problem. Thus, this paper, a fuzzy PI is proposed enhance automatic generation co...

Carbon dioxide (CO(2)) excretion and acid-base regulation in fish are linked, as in other animals, though the reversible reactions of CO(2) and the acid-base equivalents H(+) and HCO(3)(-): CO(2)+H(2)O<-->H(+)+HCO(3)(-). These relationships offer two potential routes through which acid-base disturbances may be regulated. Respiratory compensation involves manipulation of ventilation so as to ret...

background and objective : poor sleep, poor quality of sleep and sleepiness are among the common problems as-sociated with learning, memory and educational performance in children and adolescents. considering the lack of pre-vious literature in this field, especially in the city of yazd, iran, a number of high-school students of the city participat-ed in a study to assess sleep problems and inf...

Interpreting acid base disturbances according to the physicochemical Stewart approach allows the cause of such abnormalities to be discovered. This method is based on three independent variables: SID (strong ion difference), mainly sodium and chloride; weak acids concentration — Atot, mainly albumins and phosphate; and carbon dioxide tension — pCO2. These three independent variables are respons...
