In this work, an optimal and robust controller based on consolidating the PID H-infinity approach with model reference control is proposed. The proposed intended to accomplish a satisfactory transient response by including model. A Tail-Sitter VTOL UAV system used show effectiveness of controller. dynamic formulated using Euler method. To optimize design procedure, Black Hole Optimization (BHO)...
in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...
The design and construction of the trackbed support structure is extremely important for controlling track settlement, dynamic deflection, and the overall quality of the trackbed. These factors largely influence the long-term performance of the track relative to maintaining adequate geometric features for efficient and safe train operations. Performance-based design methods provide design crite...
We develop a formal verification procedure to check that elastic pipelined processor designs correctly implement their instruction set architecture (ISA) specifications. The notion of correctness we use is based on refinement. Refinement proofs are based on refinement maps, which—in the context of this problem—are functions that map elastic processor states to states of the ISA specification mo...
In this short report, I discuss the way in which an assumption at the outset of a longitudinal study on HIV-positive mothers has been challenged three years into the study. The assumption concerns the employment status of the participants. The Kgolo Mmogo project is investigating the resilience factors in mothers (n=440) and children (n=440) who are dealing with the affect and effects of HIV&AI...
In determining the etched track rate in solid-state nuclear track detectors, track lengths should be determined accurately. A method based on surface profilometry is proposed to determine the track lengths in CR-39 detectors through measurements of their replicas. Tracks from alpha particles with an incident energy of 4 MeV have been chosen to demonstrate the method. After irradiation and chemi...
Ion tracks formed in amorphous Ge by swift heavy-ion irradiation have been identified with experiment and modeling to yield unambiguous evidence of tracks in an amorphous semiconductor. Their underdense core and overdense shell result from quenched-in radially outward material flow. Following a solid-to-liquid phase transformation, the volume contraction necessary to accommodate the high-densit...
اثر ذرات بر روی سلولزاستات با بررسی رگه (track) های ایجاد شده، در هنگامیکه این پلاستیک قبل از اثر این ذرات بدرجات مختلف حرارت داده شده بود، مورد مطالعه قرار گرفت . پیشرفت مشخصی در حساسیت پلاستیک برای تشکیل این رگه ها در هنگامیکه این پلاستیک حداقل بمدت سه ساعت در 140 درجه سانتیگراد حرارت داده شد، بدست آمد، خوردن پلاستیک در رگه ها (etching) بوسیله محلول 2ˆ6 نرمال naoh در 40 درجه سانتیگراد انجام گ...
