A CAD (computer aided design) analysis software package (CADVIEW) was designed for use with prosthetic and orthotic CAD CAM (computer aided design/computer aided manufacture) systems. Using the Microsoft Windows 3.1 environment, CADVIEW provides a series of anatomical shape viewing and analysis tools. These tools include simultaneous display of multiple sockets and multiple views, two dimension...

Previous postmortem anatomical studies have demonstrated differences between male and female in the size and shape of the splenium of the corpus callosum. The current study using the magnetic resonance imager compares the corpus callosum in 20 transsexuals and 40 controls to determine if the anatomic variance is related to anatomic sex or gender identity. No statistical differences were found i...

The present paper analyzes radio signal propagation in long tunnels with different cross sectional size and shape at various signal carrier frequencies, transmitter/receiver positions and material properties applying computer simulations. The influences of different parameters were investigated and results were compared to the empirical four-slope path loss model for long tunnels. It was shown ...

To study the design method of sectional area and initial tension of wire rope brace of the prestressed braced steel moment frame structure system, theoretical analysis of this structure system is conducted in this paper. The lateral stiffness formula is derived. It reveals the lateral stiffness is related to the lateral stiffness of bare steel moment frame, story height, the distance between co...

In this paper a new approach to recognition of single 3D curved objects is proposed. Horizontal cross-sectional slice shapes are used for 3D object representation. 3D object recognition is accomplished by matching the cross-sectional slice shapes of an input object with those of each object model. Thus, 2D image analysis techniques can be used for slice shape matching, including the use of the ...

We present a method for estimating the vocal-tract area function from specified formant frequencies. The method extends the work of Story (J.A.S.A., 119, 715-718, 1996) based on a sensitivity function representing the change in the formant frequency due to a small perturbation of the cross-sectional area of the vocal tract. Our method estimates the vocal-tract shape through an iterative procedu...
