Prior knowledge can be introduced into system identiication problems in terms of constraints on the parameter space, or regularizing penalty functions in a prediction error criterion. The contribution of this work is mainly an extention of the well known FPE (Final Prediction Error) statistic to the case when the system identiication problem is constrainted and contains a regularization penalty...
A common strategy for extracting the feature and to preserve the global structure such as Principal Component Analysis, Two Dimensional Principal Component Analysis and Linear Discriminant Analysis have been used. These schemes are a classical linear technique that projects the data along the directions of maximum variance. To improve the performance, Locality Preserving Projection is used. The...
In this study, the tensile strength, impact strength, and the hardness of the weld are determined. A criterion is proposed for describing the effect of residual stress on the weld mechanical properties. Dimensionless parameters such as Rya (the average of residual stress over the material yield strength), Rym (the maximum residual stress over the material yield strength), ...
This research was carried out to determine the optimum conditions for acidic extraction of gelatine from cattle bones. The effects of different treatments such as pH (1.8 to 2.6), temperature (60 to 80°C) and time (40 to 120minutes) on yield of extraction, gel strength, viscosity and absorption (420 nm) was measured. Coefficients of central composite rotatable design (CCRD) and regression surf...
Maintain the best posture to use the maximum Force Grip is important in the design of work stations. The objective of this study was to measure grip strength and perceived discomfort at different hand positions and to investigate the effects of hand positions on grip strength and perceived discomfort among24 tractor drivers in Sanandaj. The maximum force grip in different Postures by hydraulic ...
When weight loss (WL) is necessary, athletes are advised to accomplish it gradually, at a rate of 0.5-1 kg/wk. However, it is possible that losing 0.5 kg/wk is better than 1 kg/wk in terms of preserving lean body mass (LBM) and performance. The aim of this study was to compare changes in body composition, strength, and power during a weekly body-weight (BW) loss of 0.7% slow reduction (SR) vs. ...
Introduction: Progranulin (PGRN) has been recently introduced as a new indicator of chronic inflammatory response in type 2 diabetes. The present study aimed to investigate the effect of combined training on serum levels of progranulin, glycosylated hemoglobin (HbA1c), and insulin resistance in overweight and obese women with type 2 diabetes. Materials and Methods: A total of 36 women were divi...
