This paper explores whether words used to describe pipe organ ensembles have correlation with specific spectral features. Similar previous work has concentrated on single pipes in anechoic conditions (e.g. Rioux, 2001). This work examines pipe organ ensembles as a cohesive whole. Ninety-nine English-speaking subjects were asked to describe recordings of pipe organs. From the many timbral adject...

Up to 20 percent of the German sewerage systems are damaged mainly due to their high age. The estimation for the restoration costs is about 100 billions DM. As a consequence the German Government has issued comparably harsh environmental laws enforcing the owner of a sewerage system to check regularity its state by means of suitable inspection technology. However, at the present state of the ar...

Based on the current situation of high precision and comparatively low APA (absolute positioning accuracy) in industrial robots, a calibration method to enhance robots is proposed. In view "hidden" characteristics RBCS (robot base coordinate system) FCS (flange measurement process, general proposed, source robot terminal position error classified into three aspects: RBCS, kinematics parameter m...

This document contains additional comparisons of our approach and commercial software [1] on large real-world datasets. 1 Additional ExperimentsSection 2.3 of the paper introduced commercial software [1] as a state-of-the-art technique of pipe-run reconstruction. We purchased a license and used theirautomatical pipeline to reconstruct pipe-runs from the same dataset in Figure11 ...

Finite element simulation of stretch flanging process was carried out in order to investigate the effect of process parameters on maximum thinning (%) in stretch flanging process. Influences of initial flange length, punch die clearance, width of sheet metal blank and blank holding force were investigated on maximum thinning (%). Finite element simulation was done using FEM software package ABA...

Existing welded steel moment frames are designed to tolerate substantial yielding and plastic rotation under earthquake loads. This sacrificial design approach can lead to permanent, and often irreparable damage when interstory drifts exceed 2%. The experimental seismic performance of a 50% full-scale damage avoidance designed structural steel beam-column connection is presented. The beamcolumn...

The safe operation of petrochemical plant requires screening of the pipework to ensure that there are no unacceptable levels of corrosion. Unfortunately, each plant has many thousands of metres of pipe, much of which is insulated or inaccessible. Conventional methods such as visual inspection and ultrasonic thickness gauging require access to each point of the pipe which is time consuming and v...

habilitation of patients who have undergone extensive surgery for eradication of neoplasm of the maxillae requires restoration of the functions of speech, mastication, and deglutition. The options for rehabilitation of these patients are surgical reconstruction or prosthetic restoration. According to Sharry,’ even when surgical techniques are available, prosthetic reconstruction is chosen most ...
