-Stiffness modulation scheme for a robotic driving system with redundant actuation was investigated in this paper. The dynamic and the stiffness models of a simple system having one link and two prismatic actuators were derived and employed for computational simulations of dynamic response to an initial disturbance. Several combinations with different types of elastic elements were applied to t...
این پایان نامه به بررسی و مقایسه دو موضوع مطابقه میان فعل و فاعل (از نظر شخص و مشار) و هسته عبارت در دو زبان انگلیسی و آذربایجانی می پردازد. اول رابطه دستوری مطابقه مورد بررسی قرار می گیرد. مطابقه به این معناست که فعل مفرد به همراه فاعل مفرد و فعل جمع به همراه فاعل جمع می آید. در انگلیسی تمام افعال، بجز فعل بودن (to be) از نظر شمار با فاعلشان فقط در سوم شخص مفرد و در زمان حال مطابقت نشان میدهند...
The mechanisms that link metabolic syndrome (MetS) to increased cardiovascular risk are incompletely understood. We examined whether MetS is associated with the neural baroreflex pathway (NBP) and whether any such associations are independent of blood pressure values.This study involved the cross-sectional analysis of data on 2835 subjects aged 50 to 75 years from the Paris Prospective Study 3....
PURPOSE There is a discussion in literature concerning mechanical properties and modelling of surgical meshes. An important feature of elastic modulus dependency on load history is taken into account in this paper, as implants are subjected to variable loading during human activity. The example of DynaMesh®-IPOM surgical implant is studied. METHODS The analysis is based on failure tension tes...
The use of generative design as an alternative to typical structural optimization techniques opens the door new methods manufacturing. In this study, were used automated iterative process with extensive set control variables and initial models explore optimise stiffness weight different configurations for a 3 MW offshore wind turbine electrical generator structure. With approach adding process,...
Acute rheumatic fever (ARF) is associated with systemic inflammation and arterial stiffness during the acute stage. It has not been reported if arterial stiffness remains after recovery. The aim of this study was to determine the arterial stiffness during acute stage and 6 months after recovery from ARF. Arterial stiffness was assessed by carotid femoral pulse wave velocity (PWV) in 23 ARF pati...
BACKGROUND Lower extremity stiffness is thought to be an important factor in musculoskeletal performance. However, too little or too much stiffness is believed to increase the risk of musculoskeletal injury. PURPOSE To provide a current update of the lower extremity stiffness literature as it pertains to both performance and injury. SUMMARY It appears that increased stiffness is beneficial ...
Introduction: Nowadays, owing to industrial activities heavy metals alongside chemical and physical pollutants are discharged to the environment resulting in extensive pollution of water bodies. Thus, simultaneous reduction of hexa-valent chromium and nitrate using granular zero-valent magnesium was studied. Methods: The current experimental study was conducted in 250 ml erlens on a shaker a...
