One thing is completely for sure, Pittsburgh has a pretty diverse tech industry. From software to Internet companies to outfits developing nanotechnologies, our bases are covered. Check out this bunch of headlines from the previous week:
NEXT GENERATION FEEDBACK ADVANCES MARKETPLACE RELIABILITY
Guru.com, the world’s largest online marketplace for freelance talent, announced today a proprietary Feedback Management methodology to improve the value of subjective comments or rankings on its site. For the first time in any online marketplace, subjective feedback will be validated against actual performance metrics to provide greater assurances of quality while limiting misuse.
A common Web convention, feedback is traditionally posted for public review with minimal intervention or modification. The practice typically entails the submission of remarks or rankings by one party in a transaction to capture, share, and guide public opinion about the other party.
Feedback Management preserves the natural order and use of Feedback as a decision-making tool while neutralizing its tendencies to illogically bias choice or to inhibit honesty. Users are invited to block some unwarranted feedback but only in proportion to their prior, proven success. Negative feedback is not fully suppressed; rather its exposure is made more reliably predictive. Objective performance metrics determine a variable blocking rate, or ‘Blocking Power,’ which is calculated for each user in real-time. A seven day review-and-approval period is allowed for assessment of individual feedback records prior to public disclosure.
“Current Feedback standards create an assumption of validity predicated on transparency,” explained Inder Guglani, CEO and Founder of Guru.com. “But as incomplete information and fear of retaliation are introduced into the Feedback process, transparency requires objective verification.”
PLEXTRONICS WINS MATERIALS AWARD
Plextronics, Inc. — an international technology company that specializes in printed solar, lighting and other organic electronics — was awarded the 2008 Technical Development Materials Award by IDTechEx. The company was presented with the honor at the Printed Electronics 2008 Awards dinner in San Jose on December 3.
A panel of judges, which was comprised of an independent international advisory board, was charged with finding the most impressive material development in all of printed electronics during the last 12 months. Plextronics’ launch of its Plexcore® PV 1000 and Plexcore® PV 2000 ink systems for use in research-scale printed solar cell development was chosen as the winner.
Andy Hannah, President and CEO of Plextronics, said, “We are very proud of this new ink system — it enables our customers access to the materials and technology that can help them consistently achieve state-of-the-art OPV efficiencies, potentially nearing world-record champion results.”
Developed around Plextronics’ organic photovoltaic technology – which was certified by NREL earlier this year at 5.98 percent efficient – next generations of the Plexcore® PV ink systems will be designed for use in pilot and early manufacturing lines, further advancing commercial production on an industry-wide level.
ALGOR FEA HELPS NORTH AMERICAN SHIPBUILDING HOIST 1,000 TONS
Located along the intercoastal waterway in Larose, Louisiana, North American Shipbuilding (NAS) designs and constructs offshore vessels for its parent company, Edison Chouest Offshore (ECO), and affiliated companies. As part of its ship building and repairing operations, NAS uses finite element analysis (FEA) software from ALGOR, Inc. in Pittsburgh.
“ALGOR FEA allows us to check our first principal calculations as well as investigate more detailed problems,” said Jacob Cheramie, Naval Architect of NAS. For example, when a new anchor-handling tug supply vessel was built, a 1,000-ton superstructure needed to be lifted by cranes for installation on the hull. Engineers at NAS performed ALGOR linear static stress analyses of key components to ensure that the ship could withstand the forces generated during the lifting operation. The FEA stress and displacement results verified NAS’ calculations, which allowed NAS to proceed with confidence and execute the crane lift successfully.

North American Shipbuilding (NAS) of Larose, Louisiana, crane-lifted this 1,000-ton superstructure as part of the assembly process for a new anchor-handling tug supply ship. Engineers at NAS used ALGOR FEA software to analyze key components to verify that the ship could withstand the lifting operation.
