با گسترش مفهوم مدیریت بار، نگرش یک سویه در طراحی و بهره برداری از سیستمهای قدرت جای خود را به بررسی همه جانبه آن می سپارد. این بررسی در برگیرنده نیازها و بهبود عملکرد تولیدکننده و مصرف کننده است . در این پایان نامه سعی شده است تا مفهوم مدیریت بار در ارزیابی قابلیت اعتماد سیستمهای قدرت به کار رود. بدین منظور ارزیابی reliability cost/worth براساس مفهوم day type انتخاب شده است . این انتخاب برای نم...
BACKGROUND In recent decades, parents have been involved in programs that aim to improve parenting style and reduce child behavior problems. Research of preventive parenting programs has shown that these interventions generally have a positive influence on both parents and children. However, to our knowledge there is a gap in the scientific literature when it comes to randomized controlled tria...
Walking humans spontaneously select different speed, frequency and step length combinations, depending on which of these three parameters is specified. This behavior can be explained by constrained optimization of cost of transport (metabolic cost/distance) where cost of transport is seen as the main component of an underlying objective function that is minimized within the limitations of speci...
The present study suggests a model for predicting liquidity gap, based on source and cost of funds approach concerning the daily time series data (25 March 2009 to 19 March 2018), in order to control and manage the liquidity risk. Using the family of autoregressive conditional heteroscedasticity models, the behavior of bank liquidity gap is modeled and predicted. The results show that the APGAR...
While there exists extensive literature on software cost estimation techniques, industry practice continues to rely upon standard regression-based algorithms. These software effort models are typically calibrated or tuned to local conditions using local data. This paper cautions that current approaches to model calibration often produce sub-optimal models because of the large variance problem i...
