abstractobjective: to investigate the impact of respiratory motion on localization, and quantification lung lesions for the gross tumour volume utilizing an in-house developed auto3dreg programme and dynamic nurbs-based cardiac-torso digitised phantom (ncat). methods: respiratory motion may result in more than 30% underestimation of the suv values of lung, liver and kidney tumour lesions. the m...

In this paper we investigate the cluster behavior of linearly interacting Brownian motions indexed by Z. We show that (on a logarithmic scale) the block average process converges in path space to Brownian motion. c © 2000 Elsevier Science B.V. All rights reserved.

We give a complete analytical characterization of the functions transforming reflected Brownian motions to local Dirichlet processes.

Target motion analysis (TMA) visualisation is used by naval ships to locate targets around ownship when more accurate methods such as active sonar are not viable. TMA utilises an array of data, the main source being passive sonar, and results in an almost infinite number of possible solutions. These solutions must be filtered by the TMA operator to identify the most probable or hazardous soluti...

The science of human motion analysis is fascinating because of its highly interdisciplinary nature and wide range of applications. Histories of science usually begin with the ancient Greeks, who first left a record of human inquiry concerning the nature of the world in relationship to our powers of perception. Aristotle (384-322 B.C.) might be considered the first biomechanician. He wrote the b...

This paper aims to investigate the effects of motion duration on the structural seismic demands, seeking potential correlations between motion durations and structural responses at several seismic intensity levels. Three seismic intensity levels with 100years, 475years, and 2475years earthquake return periods (RPs) are first considered for correlation computations. Spectrally matched ground mot...

Motion is an important cue in videos that captures the dynamics of moving objects. It helps in effective analysis of various event related tasks such as human action recognition, anomaly detection, tracking, crowd behavior analysis, traffic monitoring, etc. Generally, accurate motion information is computed using various optical flow estimation techniques. On the other hand, coarse motion infor...

this paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. the cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. hamilton's principle is used to d...

Performance and reliability of any rotating machine can be studied by proper dynamic analysis of the machine. In this regard, this paper presents the method to study the dynamic response of the shaft of a Pelton turbine due to the impact of water jet. Equations of motion for the bending vibration of Pelton turbine assembly, in two transverse directions, is developed by using Lagrange equation o...
