بدافزار به نرم افزاری گفته می شود که نیت خرابکارانه یا اثرات تخریبی دارد. با توجه به اینکه بدافزارها می توانند خرابی های جبران ناپذیری به بار آورند و به سرعت در حال گسترش و تکامل می باشند لذا شناسایی بدافزارها امری بسیار مهم و حیاتی می باشد. رایج ترین روشی که برای شناسایی بدافزارها استفاده می شود، روش های مبتنی بر امضا است. این روش موثر و کارا است و سرعت زیادی دارد اما فقط قادر به شناسایی بدافز...

Parallel Cellular Automata (PCA) previously has been employed for optimizing bi-objective reservoir operation, where one release is used to meet both objectives. However, if a single release can only be used for one objective, meaning two separate sets of releases are needed, the method is not applicable anymore. In this paper, Multi-Step Parallel Cellular Automata (MSPCA) has been developed fo...

Two-sided assembly lines are designed to produce large and complex products, where workers can perform on both sides at the same time. This paper establishes a mathematical model for multi-objective two-sided line balancing problems with additional constraints (MOATALBP). The considers workers’ skill balance of line, aimings maximize efficiency minimize cost smoothness index. A harmony search a...

Identifying the appropriate software components in the software design phase is a vital task in the field of software engineering and is considered as an important way to increase the software maintenance capability. Nowadays, many methods for identifying components such as graph partitioning and clustering are presented, but most of these methods are based on expert opinion and have poor accur...

در این پژوهش، یک مدل دوهدفه برای مسئله مکان‌یابی-مسیریابی محصولات فاسدشدنی همراه با پنجره زمانی نرم ارائه شده است که هدف اول آن کمینه کردن هزینه‌های موجود و هدف دوم حداکثر کردن عمر ماندگاری محصولات می‌باشد. به منظور اعتبار‌‌سنجی مدل ارائه شده، تعدادی مسئله نمونه به‌صورت تصادفی و به کمک داده‌های مقالات معتبر تولید گردیده است. مسئله در محیط نرم‌افزار بهینه‌سازی GAMS کد شده و با روش محدودیت اپسیلو...

in this paper, lift and drag coefficients were numerically investigated using numeca software in a set of 4-digit naca airfoils. two metamodels based on the evolved group method of data handling (gmdh) type neural networks were then obtained for modeling both lift coefficient (cl) and drag coefficient (cd) with respect to the geometrical design parameters. after using such obtained polynomial n...
