Information technology and economic performance: A critical review of the empirical evidence
Jason Dedrick, Vijay Gurbaxani, Kenneth L. Kraemer
Pages: 1-28
DOI: 10.1145/641865.641866
For many years, there has been considerable debate about whether the IT revolution was paying off in higher productivity. Studies in the 1980s found no connection between IT investment and productivity in the U.S. economy, a situation referred to as...

A survey of processors with explicit multithreading
Theo Ungerer, Borut Robič, Jurij Šilc
Pages: 29-63
DOI: 10.1145/641865.641867
Hardware multithreading is becoming a generally applied technique in the next generation of microprocessors. Several multithreaded processors are announced by industry or already into production in the areas of high-performance microprocessors,...

View planning for automated three-dimensional object reconstruction and inspection
William R. Scott, Gerhard Roth, Jean-François Rivest
Pages: 64-96
DOI: 10.1145/641865.641868
Laser scanning range sensors are widely used for high-precision, high-density three-dimensional (3D) reconstruction and inspection of the surface of physical objects. The process typically involves planning a set of views, physically altering the...
