This study investigates the effect of an inductance model on sensorless control performance a synchronous reluctance motor (SynRM). A high-frequency voltage injection method based position dependence and extended electromotive force estimation are applied to achieve control. More specifically, inductances modeled in several patterns two methods. Subsequently, characteristics steady transient st...

soil hydraulic properties such as saturated and unsaturated hydraulic conductivity play an important role in environmental research. since direct measurement of these soil hydraulic properties is time-consuming and costly, indirect methods such as pedotransfer functions and artificial neural networks (ann) were developed based on readily available parameters. in this study, the use of ann to pr...

abstract determining saturated hydraulic conductivity (ks) is one of the important soil characteristics that its estimation is important in soil and water studies. there are several methods for estimating ks in unsaturated conditions. these methods include the inversed-auger-hole method, the double-ring infiltrometer and the single-ring pressure infiltrometer. the measurement of ks by these met...

the aim of this study was to determine the fatty acid and mineral composition in bone of 3 pelagic fish: gold stripe sardine (sardinella gibbosa), anchovy kilka (clupeonella engrauliformis) and indian anchovy (stolephorus indicus). fatty acid profiles showed that total saturated fatty acid have no significant differences in 3 species. the content of total mono saturated fatty acids in anchovy k...

to investigate the saturation induced collapse deformation behavior of rockfill material, a set of large-scale triaxial tests were conducted in saturated and dry-saturated conditions. specimens were tested under various confining pressures. for dry-saturated tests, specimens were sheared in various stress levels. results of all dry saturated tests indicate a sudden reduction in the specimen vol...
