Three New Corpora at the Bavarian Archive for Speech Signals - and a First Step Towards Distributed Web-Based Recording

The Bavarian Archive for Speech Signals has released three new speech corpora for both industrial and academic use: a) Hempels Sofa contains recordings of up to 60 seconds of non-scripted telephone speech, b) ZipTel is a corpus with telephone speech covering postal addresses and telephone numbers from a real world application, and c) RVG-J, an extension of the original Regional Variants of German corpus with juvenile speakers. All three corpora were transcribed orthographically according to the SpeechDat annotation guidelines using the WWWTranscribe annotation software. Recently, BAS has begun to investigate performing large-scale audio recordings via the web, and RVG-J has become the testbed for this type of recording

Manual actuator

An actuator for an exercising machine employable by a crewman aboard a manned spacecraft is presented. The actuator is characterized by a force delivery arm projected from a rotary imput shaft of an exercising machine and having a force input handle extended orthogonally from its distal end. The handle includes a hand-grip configured to be received within the palm of the crewman's hand and a grid pivotally supported for angular displacement between a first position, wherein the grid is disposed in an overlying juxtaposition with the hand-grip, and a second position, angularly displaced from the first position, for affording access to the hand-grip, and a latching mechanism fixed to the sole of a shoe worn by the crewman for latching the shoe to the grid when the grid is in the first position

Collapse of composite tubes under end moments

Cylindrical tubes of moderate wall thickness such as those proposed for the original space station truss, may fail due to the gradual collapse of the tube cross section as it distorts under load. Sometimes referred to as the Brazier instability, it is a nonlinear phenomenon. This paper presents an extension of an approximate closed form solution of the collapse of isotropic tubes subject to end moments developed by Reissner in 1959 to include specially orthotropic material. The closed form solution was verified by an extensive nonlinear finite element analysis of the collapse of long tubes under applied end moments for radius to thickness ratios and composite layups in the range proposed for recent space station truss framework designs. The finite element analysis validated the assumption of inextensional deformation of the cylindrical cross section and the approximation of the material as specially orthotropic
