Software Technologies For Wireless Applications
David Ni, Crescentec and Memes Technology, Danville
02/13/2003
The continuous growth of wireless applications such as cellular phones and wireless LAN has been pushing the vendors searching more new technologies for service deployment, feature enhancement and cost reduction. This talk will focus on some ofsoftware technologies, which are important to different stages of wireless application development: from RF IC design, telecom/wireless standard/architecture, and service infrastructure. We will discuss some challenges in each area and the related computing disciplines.
A Brush With Fame, Digital Artwork And Dozens Ofdeadly Weapons
Bill Nelson, Petaluma
02/20/2003
A chronicle of the journey of a non-digital artist into the world of bits, bytes and bus. Digital imagery has changed our perception of the world in many ways, in particular how we SEE it. How do we translate from an analog world into the digital realm? Even our actors may become digital representations. How do we come to relate in a meaningful way with a world consisting of ephemeral differences in voltage andgenerated images? Learning to live with and love an interactive world within a Graphical User Interface.
Early Supercomputers And Disassemblers
Steve Jasik, Jasik Designs, Menlo Park
02/27/2003
Steve Jasik talks about the 1st supercomputers of the 1960's, the Control Data 6600 and 7600, and about the global disassembler MacNosy. Mr Jasik was associated with Control Data from 1967 to 1984 where he worked on the FORTRAN compiler, mostly the code optimizer. At the time the 6600 was the first computer with multiple functional units and a micro parallel architecture, it presented some unique problems for those who tried to generate code for it. In 1984 wrote the first global disassembler, MacNosy for then new Apple Macintosh computer.
When Can I Buy A 50" 1920X1080 Hdtv With High Brightness For 999$?

MicroDisplay Corporation creates HD-resolution LCOS (liquid crystal on silicon) display chipsets for use in optical projection systems. MicroDisplay panels are capable of 500 frame per second operation allowing their use in single-panel projection systems. Single panel systems offer substantial cost and quality advantages over the three-chip (one for red, green and blue) alternatives. MicroDisplay's single paneloperation is enabled by 1) high speed electronics 2) fast, high contrast, TN liquid crystals (80 microsecond switch time) 3) ability to manufacture thin (fast) layers ofliquid crystal material at our manufacturing facility in San Pablo. This technology is about to be become widely available, and will likely find uses in other newer, currently high-end, display technologies.
Solving The Knight's Tour With A Genetic Algorithm

The Knight's Tour puzzle has captured the imagination of mathematicians and chessplayers for centuries. The goal is to find paths through a chessboard with standard chess knight moves, touching every square exactly once. A simple hill-climbingsolution is presented, and applied to a random population of 1 million individuals. The same framework is then used as the basis for a Simple Genetic Algorithm (SGA), which evolves 1 million individuals with simulated natural selection, crossover, and mutation. Running time is identical for both cases. The results of the two experimentsare compared, and the efficacy of the SGA on this problem is evaluated. The experiments were done at Sonoma State University and at CSU Sacramento by theauthor, with SSU Alumnus Terry Slocum.
