[Purpose] Our objective was to evaluate the residual dynamic and static functionality in the sitting position of hemiplegic stroke patients who require help to pull their lower garments up and down during toileting. [Subjects and Methods] The subjects were 11 hemiplegic patients. We gathered data on the patients' motor paralysis, sensory capacity, lower extremity muscle strength, trunk control,...
This paper presents the advantages of a strong coupled formulation to model the electro-mechanical coupling appearing in MEMS. The classical modeling approach is to use a staggered methodology iterating between two different programs to obtain the solution of the coupled problem. In this research a strong coupled formulation is proposed and a tangent stiffness matrix of the whole problem is com...
در این پژوهش ناپایداری pull-in نانو سوئیچ یکسر درگیر و دوسر درگیر تحت تاثیر اثر اندازه و نیرو¬های درون مولکولی شامل نیروی واندروالس و نیروی کازیمیر با استفاده از روش حل تفاضلات مربعی (dqm) بررسی می¬گردد. در این نانوعملگر، نیروی الکترواستاتیک به عنوان نیروی محرک بکار رفته و برای بررسی اثرات غیرخطی هندسی از جابجایی¬های غیر خطی وون-کارمن استفاده شده است. به منظور استخراج معادله¬¬ی غیر خطی حاکم به ...
We present a novel visual attention tracking technique based on Shared Attention modeling. Our proposed method models the viewer as a participant in the activity occurring in the scene. We go beyond image salience and instead of only computing the power of an image region to pull attention to it, we also consider the strength with which other regions of the image push attention to the region in...
Synthesis of dynamic combinatorial libraries acylhydrazones in the presence a G-quadruplex DNA template, followed by pull-down with streptavidin-coated magnetic beads, allows identification putative binders.
The operational range of electrostatic MEMS parallel plate actuators can be extended beyond pull-in in the presence of an intermediate dielectric layer, which has a significant effect on the behavior of such actuators. Here, we study the behavior of cantilever beam electrostatic actuators beyond pull-in using a beam model along with a dielectric layer. The results from the simple beam model are...
We propose an energy-based framework to analyze the statics and dynamics of a ferroelectric negative capacitance-hybrid microelectromechanical system (MEMS) actuator. A mapping function that relates charge on displacement movable electrode is used obtain Hamiltonian hybrid actuator in terms displacement. then use graphical energy–displacement phase portrait plots static pull-in, dynamic pull-ou...
This article deals with effects of thermal stresses on stability and frequency response of a fully clamped circular microplate, which acts as the diaphragm of a capacitive MEMS microphone. Static and dynamic pull-in phenomena limit the stable regions of a capacitive MEMS microphone. The results show that the non-dimensional static pull-in voltage of the studied case is about 5.23 (38.6 V). On t...
I feel somewhat relaxed and freer since I resigned from the position of Vice Minister of Finance for International Affairs about a month ago. At least now I don’t have to worry about what I say about the yen/US dollar rate for the wire people who used to follow me all over the world. I would like to remind you that what I say today does not necessarily reflect the official views of the Japanese...
