Introduction: Photon contamination is a restriction on treatment with electron that increase dose to healthy tissue below the tumor. The aim of this study is to reduce the photon contamination using a magnet system. Materials and Methods: A mini-applicator equipped with two neodymium boron permanent magnets was designed which make it possible to adjust the d...

In this work, a fiber Bragg grating (FBG) sensing system which can measure the transient response of out-of-plane point-wise displacement responses is set up on a smart cantilever beam and the feasibility of its use as a feedback sensor in an active structural control system is studied experimentally. An FBG filter is employed in the proposed fiber sensing system to dynamically demodulate the r...

The determination of displacement vectors is an important task in the context of temporal image sequence analysis, as well as in stereoscopic vision. The relations between images taken from an image sequence or a stereo pair are conceptually represented by a displacement vector field which establishes a pairwise correspondence between points in both regarded images. Most approaches for the dete...

This study describes a wireless laser displacement sensor node that measures displacement as a representative damage index for structural health monitoring (SHM). The proposed measurement system consists of a laser displacement sensor (LDS) and a customized wireless sensor node. Wireless communication is enabled by a sensor node that consists of a sensor module, a code division multiple access ...

introduction: it is believed that locus coeruleus (lc) influences the sensory information processing. however, its role in cortical surround inhibitory mechanism is not understood. in this experiment, using controlled mechanical displacement of whiskers we investigated the effect of phasic electrical stimulation of lc on response of layer v barrel cortical neurons in anesthetized rat. methods: ...

Mapping deformation field time-series, including vertical and horizontal motions, is vital for landslide monitoring and slope safety assessment. However, the conventional differential synthetic aperture radar interferometry (DInSAR) technique can only detect the displacement component in the satellite-to-ground direction, i.e., line-of-sight (LOS) direction displacement. To overcome this constr...

We develop a new paradigm for thin-shell finite-element analysis based on the use of subdivision surfaces for: i) describing the geometry of the shell in its undeformed configuration, and ii) generating smooth interpolated displacement fields possessing bounded energy within the strict framework of the Kirchhoff-Love theory of thin shells. The particular subdivision strategy adopted here is Loo...

in this paper, a thermoelasticity solution for steady state response of thick cylinders which are subjected to pressure and external heat flux in inner surface is presented. displacement field obeys the kinematics of the first order shear deformation theory (fsdt). it is assumed that the temperature varies both along the length and the thickness. the variation of the temperature occurs linearly...

In this manuscript we propose a structural condition on nonseparable Hamiltonians, which term displacement monotonicity condition, to study second-order mean field games master equations. A rate of dissipation bilinear form is brought bear global (in time) well-posedness theory, based priori uniform Lipschitz estimates the solution in measure variable. Displacement being sometimes dichotomy wit...
