[ 1 ] - Survival analysis of breast cancer patients with different chronic diseases through parametric and semi-parametric approaches
Introduction: There is a lack of information on the extent of dependency between chronic diseases and the survival rate of breast cancer. Until date, none of the models proposed has determined the impact of chronic diseases on breast cancer survival. This study, therefore, aimed to investigate the impacts of chronic diseases such as diabetes, blood pressure, and endocrine di...

[ 6 ] - شناسایی نقطه تغییر در بردار میانگین فرآیند نرمال دومتغیره با تغییرات مونوتونیک
When a control chart shows an out-of-control condition, a search begins to identify and eliminate the root cause(s) of the process disturbance. The time when the disturbance has manifested itself to the process is referred to as change point. Identification of the change point is considered as an essential step in analyzing and eliminating the disturbance source(s) effectively. When a process...
[ 7 ] - شناسایی نقطة تغییر در داده‌های پانلی به روش هم‌زمان میانگین متحرک موزون‌نمایی و جمع تجمعی
شناسایی نقطة تغییر در داده‌های پانلی به کارشناسان کمک می‌کند تا دریابند مقاطع داده‌ها در چه زمانی تغییر کرده است. شناسایی این زمان به تحلیل واقعی‌تری از تغییرات در فرایند می‌انجامد. روش‌های مختلفی برای شناسایی نقطة تغییر در داده‌های پانلی معرفی شده است، اما افزایش حساسیت روش‌ها در شناسایی نقطة تغییر داده‌های پانلی، اهمیت بسیاری دارد. در این مقاله، به‌کمک رویکردی ترکیبی روشی با حساسیت بالا برای...
[ 8 ] - Wind Turbine Power Curve Modeling Using Parametric Approach
Abstract: In recent years, due to the limitation of fossil fuels and the environmental Impact of using these fuels, focusing on renewable energy sources has increased significantly. In developed countries, using clean energy such as wind power has been considered as an alternative source. Monitoring the performance of wind turbines and controlling their output power quality is one of the import...
