This paper presents analysis methods for improving the electromagnetic characteristics of a high-speed electrical multiple unit (EMU) train with a 1:1 finite-element analysis model. Both electromagnetic distribution diagrams and numerical field data have been analyzed. With this method, optimal electromagnetic conditions for the EMU compartment could be feasibly obtained, while the optimization evaluation...
3D façade modeling consists of representing architectural elements of a building in detail so that both geometry and appearance are generated in a photo-realistic 3D scene. In this article, we review four main techniques used to solve this problem: photogrammetry, sparse and dense reconstruction based on SfM (Structure from Motion) and procedural modeling. We provide a comparison of several methods...
The study of growth model is a basic research in forest growth and yield modeling. Most of growth models were developed using ordinary regression method. It is assumed that the observations were independent and obey Gauss distribution. Those models reflect the average growth across different plots, but neglect the correlation and variance between individuals and plots. However, mixed-effects models...
We present a robust approach to real-time 3D head pose tracking using multiple cameras with unknown camera placements. Many important applications do not want prior multi-camera calibration. We exploit a generic face model to overcome the difficulties due to the lack of prior knowledge of camera placement and the severe head appearance difference across cameras. We propose a fast drift-free solution...
An increasing number of semiconductor companies have research programs related to MEMS resonators. This can be explained by the possible wide range of application areas. Many resonators operate in vacuum and sealing of the cavity can be obtained by using a Wafer Level Thin Film Package (WLTFP). To fit the MEMS-die into a small package it needs to be thinned. In this paper the effect of wafer thinning...
