the ball and beam system is one of the most popular laboratory setups for control education. in this paper, we design a fuzzy pd cascade controller for a ball and beam system using asexual reproduction optimization (aro) technique. the ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. this system utilizes a servo motor to control ball’s position on the beam. chan...

objectives to explore the effect of a selective 10-week corrective exercise with an emphasis on gait training activities (gta) on the number of falls (nofs), fear of falling, functional balance, timed up and go (tug) test among pd patients. background posture instability and unsteady gait disorders in parkinson’s disease (pd) usually contribute to fall-related fractures. fall-related trauma in ...

a palladium composite membrane was prepared via electroless plating technique using organic-inorganic method during activation process. the ceramic support surface was modified by two tio2-boehmite and one γ-alumina layers to avoid pd penetration in support pores. thin and defect-free pd composite membrane was obtained by creating a relative smoothness on the ceramic support and using pd nanopa...

programmed cell death-1 (pd-1) and its ligands, pd-l1 and pd-l2, have been regarded as important immune system regulatory molecules. the aberrant expression of the molecules has been related to several autoimmune disorders. this study is aimed to assess the mrna expression level of pd-1, pd-l1, and pd-l2 molecules in the peripheral blood mononuclear mells (pbmcs) from multiple sclerosis (ms) pa...

the mechanical properties including elastic stiffness constants as well as bulk modulus of palladium (pd) nanowire were calculated in the constant temperature and pressure (npt), ensemble by molecular dynamics (md) simulation technique. the quantum sutton-chen (q-sc) many-body potential was used to calculate the cohesive energy as well as forces experience by every atoms. the temperature and pr...

this paper focused on a novel method of electroless plating ruthenium (ru) on solid or porous substrates like porous stainless steel (pss) discs or ceramic tubes. a novel complexing plating bath of ru was developed. it is proven that ru can be deposited directly on these substrates by the bath at a temperature of 328 k and strong alkaline environment. tga, sem, edx and xrd confirmed the success...
