به دلیل آن که استخراج مدل ریاضی از فرآیندهای صنعتی، دارای پیچیدگی های فراوانی است، مدل سازی بر اساس داده های ورودی و خروجی مورد استقبال بیشتری قرار گرفته است. از طرفی توجه به اصل سادگی، منجر به استفاده از ساختار مدل های چندگانه شده است. از این رو، در این پایان نامه سیستم تشخیص عیب مبتنی بر مدل های چندگانه مدنظر قرار گرفت. با استفاده از شناساگر عصبی-فازیِ محلی-خطی، بانک های مدل برای تمامیِ شرایط س...

در مطالعه عمیق روی توزیع زاویه ای پاره های شکافت در واکنش یون سنگین ناهمسانگردی های زیادی دیده شده است. این ناهمسانگردی ها را می توان توسط نظریه استاندارد آماری (tsm)(transition statistical state model) توضیح داد.46علت وجود این ناهمسانگردی ها را می توان به اسپین بالا یا z2/a هسته شکافت پذیر نسبت داد1. برای ناهمسانگردیهای بیشترمی -توان از مدل آماری انقطاع (ssm)استفاده کرد. در این مدل توزیع تصویر...
