in this paper, a new robust controller based on geometric homogeneity and adaptive integral sliding mode is proposed for a class of second order systems. the upper bound of the system disturbances is not required. fully unknown parameters have been considered in the described model and its finite–time convergence to zero equilibrium point is proved. moreover, the controller is developed in the ...

The present paper examines the effects of saturation on the time domain parameters that can be extracted from recordings of speech. The kinds of saturation we are going to discuss in the paper include clipping, zeroing and two’s complement whereas the parameters we will take into considerations include root mean square (RMS, as correlated with loudness), zero crossing rate (ZCR), auto correlati...

laparoscopic and open ovariohysterectomy were compared for the following parameters: surgical time, incision length, suture number, saturation of oxyhemoglobin (spo2), heart rate, complications,cbc findings, melbourne pain scale (mps) and gross pathology. mps pain scores were evaluated using mann-whitney u test. other parameters were evaluated using studen's t test. there were no significa...

INTRODUCTION Iron parameters like serum ferritin and iron saturation are routinely used in diagnosing iron deficiency. However, these tests are influenced by many factors. We aimed to review the accuracy of iron parameters among inpatients in an acute care hospital. MATERIALS AND METHODS From October 1997 to April 2002, bone marrow aspirate samples from patients on whom concurrent iron studie...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

vaccination pain management in infants may prevent short-term and long-term physical and mental consequences in them. As a result, this study aimed to determine and investigate the effect of breastfeeding and sensorial saturation on physiological parameters of infants after administration of pentavalent vaccine at four and six months of age. Materials and Methods: This randomized controlled fie...

background : due to the higher risk of  pain in preterm infants, pain management is important for such infants. the present study aimed to determine the effectiveness of kangaroo care on the severity of pain and physiological parameters after heel-stick in preterm infants. materials and methods: this was a prospective and randomized controlled cross-over study. twenty preterm infants allocated ...

Low-mass neutron stars are directly associated with the nuclear saturation parameters because their central density is definitely low. We have already found a suitable combination of for expressing star mass and gravitational redshift, i.e., $\ensuremath{\eta}\ensuremath{\equiv}({K}_{0}{L}^{2}{)}^{1/3}$ incompressibility symmetric matter, ${K}_{0}$, density-dependent symmetry energy, $L$. In th...
