A General Motion Model and Spatio-Temporal Filters for Computing Optical Flow

November 1, 1994

Author(s)

H Liu, Tsai H. Hong, Martin Herman, Rama Chellappa

Traditional optical flow algorithms assume local image translational motion and apply simple image filtering. Recent studies have taken two separate approaches toward improving the accuracy of computed flow: the application of spatio-temporal filtering

Accurate experimental characterization of interconnects: a discussion of "Experimental electrical characterization of interconnects and discontinuities in high-speed digital systems"

November 1, 1994

Author(s)

Roger Marks, Dylan F. Williams

This paper discusses two issues concerning the accuracy or electrical characterizations of Interconnect transmission lines, particularly in regard to a recently published paper. The error in the characteristic impedance may be reduced through an

Algorithm to Describe the Spread of a Wall Fire Under a Ceiling

November 1, 1994

Author(s)

Henri E. Mitler

After some discussion of wall fires, the effects that a ceiling has on a wall fire are analyzed and discussed qualitatively. There are two kinds of effects: first, when the upper sill of the ventilating opening lies below the ceiling (as is usual), a layer

Ambient and Vacuum Scanning Tunneling Spectroscopy of Sulfur and Oxygen-Terminated Gallium Arsenide

November 1, 1994

Author(s)

Richard M. Silver, John A. Dagata, H. W. Tseng

Tunneling spectroscopy of sulfur- and oxygen-terminated n- and p-type GaAs (110) surfaces is reported for air and ultrahigh-vacuum conditions. Simulations of the complete I-V characteristics with explicit inclusion of surface states within the planar

An Adaptive Error Correction Method Using Feature Based Analysis Technique for Machine Performance Improvement ? Part 1: Theory Deterioration

November 1, 1994

Author(s)

J Mou, S Cetinkunt, Alkan Donmez

An adaptive error correction method using a feature-based analysis technique for improving the accuracy of CNC machine tools is presented. The method described in this paper emphasizes the integration of the process-intermittent gauging and analysis

An Adaptive Error Correction Method Using Feature Based Analysis Technique for Machine Performance Improvement ? Part 2: Experimental Verification

November 1, 1994

Author(s)

J Mou, S Cetinkunt, Alkan Donmez

The development and derivation of an adaptive error correction method using an interactive inspection system and feature-based analysis technique for machine performance improvement were presented in Part I of this paper. Here, in Part II, the experimental

Comprehensive Study of Parameters for Characterizing 3-D Surface Topography III: Parameters for Amplitude and Some Functional Properties

November 1, 1994

Author(s)

W Dong, P Sullivan, K Stout

It is recognized that profiling techniques have been widely used in industry and academic research for manufacturing control and functional control of surface roughness, in some cases, however, the profiling techniques and two-dimensional (2D) parameters

Comprehensive Study of Parameters for Characterizing 3-D Surface Topography IV: Parameters for Characterizing Spatial and Hybrid Properties

November 1, 1994

Author(s)

W Dong, P Sullivan, K Stout

This is the last part in a series of reports describing a comprehensive study of parameters to characterize three-dimensional surface topography. In conjunction with other parts of the report, this paper deals with parameters used to characterize spatial
