Using the difference of dielectric constant between malignant tumor tissue and normal breast tissue, BRATUMASS (Breast tumor microwave sensor system [1]) can determine the detected target properties by analyzing the properties of target tissue back wave obtained by near-field microwave radiation. The practical experiments show that the target space and records of antenna corresponding position ...

A displacement measurement system fusing a low cost real-time kinematic global positioning system (RTK-GPS) receiver and a force feedback accelerometer is proposed for infrastructure monitoring. The proposed system is composed of a sensor module, a base module and a computation module. The sensor module consists of a RTK-GPS rover and a force feedback accelerometer, and is installed on a target...

1. If an eccentric, stationary target is flashed while a subject is performing an eye movement in the dark, can this subject make a saccade to the location in space where the target briefly appeared? Different predictions result from alternative hypotheses regarding the manner in which saccade goals are determined. Retinal error being defined as the vector from the eye position at the time of t...

BACKGROUND Set-up errors are an inherent part of radiation treatment process. Coverage of target volume is a direct function of set-up margins, which should be optimized to prevent inadvertent irradiation of adjacent normal tissues. The aim of this study was to evaluate three-dimensional (3D) set-up errors and propose optimum margins for target volume coverage in head and neck radiotherapy. M...

Displacement estimation is a key step in the evaluation of tissue elasticity by quasistatic strain imaging. An efficient approach may incorporate a tracking strategy whereby each estimate is initially obtained from its neighbours' displacements and then refined through a localized search. This increases the accuracy and reduces the computational expense compared with exhaustive search. However,...

This paper presents a simple displacement-based seismic design method for RC frames with steel damper column. As numerical example, two 10-story frame building models are shown. The results of nonlinear time-history analysis show that the peak displacement at equivalent height is close to target displacement. strength demand beam ends connected columns, and beam-damper column joints, calculated...

Abstract—This paper deals with the cutting force monitoring for intelligent end milling operations. The authors have employed displacement sensors to monitor the cutting forces, as they are cheap and small enough to be built in the spindle structure. A monitoring method, which utilizes sensitive displacement sensors, is discussed. The sensors are installed in X Y directions near the front beari...
