Reaching-law-based discrete sliding mode controllers are well known to be easy tune and robust with respect disturbance. In recent years, it has been demonstrated that their robustness can further enhanced the use of arbitrary relative degree variables. However, reaching laws using such variables only ensure a good performance system when perturbations affecting plant matched, which is very res...

Although the mobility or transport parameters, such as lift drag and pitching moments for regular-shaped particulates, are widely studied, of irregular fractal-like aggregates generated by aggregation monomers is not well understood. These particulates which ubiquitous in nature, industries have very different mechanisms compared to their spherical counterpart. A high-fidelity direct simulation...

discuss its properties and briefly describe the Direct Simulation Monte Carlo (DSMC) method (see [1]) which is widely applied in numerics. Then, in the second part of the talk, we present the Stochastic Weighted Particle Method (SWPM) which was introduced in [2]. This numerical method was developed for problems with big deviation in magnitude of values of interest. We describe the corresponding...

We present the validation of ADBSat, a novel implementation panel method including fast pseudo-shading algorithm, that can quickly and accurately determine forces torques on satellites in free-molecular flow. Our main is comparing test cases between current de facto standard direct simulation Monte Carlo (DSMC), published literature. ADBSat exhibits significantly shorter runtime than DSMC perfo...

هدف: هدف از این پژوهش بررسی واسطه‌­ای راهبردهای سازش نایافته تنظیم شناختی هیجان در رابطه باورهای فراشناختی با اضطراب امتحان بود. روش: روش حاضر توصیفی و نوع همبستگی جامعه آماری را کلیه دانش‌­آموزان پسر دوره دوم متوسطه شهر تهران سال تحصیلی 1401-1400 تشکیل دادند که تعداد 456 نفر به نمونه‏‌گیری دسترس انتخاب شرکت کردند. ابزارها شامل سیاهه ابوالقاسمی همکاران (1375)، پرسشنامه باکو دیگران (2009)، فرم ک...

A non-destructive, fast 2D profile monitor for an ion beam accelerator can be achieved by creating a high-density gas-sheet target in vacuum. It is known that gas flow through long rectangular channel with very small gap-to-width ratio effectual forming sheet. To obtain sheet the desired performance, spatial distribution of emitted molecules candidate should examined more detail. As part develo...
