Researcher Profile: Doug Hershey

Doug Thomson

This paper will present an e-procurement model to facilitate online B2B exchanges. Large organizations in Australia and around the world are increasingly implementing e-procurement, which has increased the need for services of intermediaries such as ‘emarkets’ to facilitate the process. However, both being new and unproven require theories and models to support their roles in the online procure...

Doug Downey Research Statement

My research interests lie in the areas of natural language processing, machine learning, and artificial intelligence. My approach is driven by a belief that unprecedented resources like the Web can provide new inroads into long-standing AI challenges, such as natural language understanding and the accumulation of massive bodies of knowledge. My research style tends toward the intersection of th...

A Spread Spectrum Clock Generator for DisplayPort 1.2 with a Hershey-Kiss Modulation Profile

This paper describes a spread spectrum clock generator (SSCG) circuit for DisplayPort 1.2 standard. A Hershey-Kiss modulation profile is generated by dual sigma-delta modulators. The structure generates various modulation slopes to shape a non-linear modulation profile. The proposed SSCG for DisplayPort 1.2 generates clock signals with 5000 ppm down spreading with a Hershey-Kiss modulation prof...
