Using this framework, we classified the business models of all 10,970 publicly traded firms in the US(More)
Collaborative settings of multidisciplinary teams separated across geographical and temporal boundaries call for an integrated framework to support intelligent and distributed CAD. This paper presents a framework to improve the a bility to represent, capture, and reuse design rationale by using: computer-supported design rationale model (DRIMER) to capture(More)
PEBBLES (Providing Education By Bringing Learning Environments to Students) is a videoconferencing system which combines traditional videoconferencing equipment with simple robotics. It allows elementary school aged children who are unable to attend school because of hospitalization or other reasons to establish a presence in their classroom with a remotely(More)
Antagonism of αvβ6 is emerging as a potential treatment of idiopathic pulmonary fibrosis based on strong target validation. Starting from an αvβ3 antagonist lead and through simple variation in the nature and position of the aryl substituent, the discovery of compounds with improved αvβ6 activity is described. The compounds also have physicochemical(More)
The paper describes a 8.125-15.625 Gbps medium-reach SerDes macro for use in a networking memory system. The SerDes employs a sub-sampling ring-oscillator phase-locked loop to obtain a large frequency range with low jitter performance. In addition, the transmitter uses a modified hybrid output driver and a multi-step duty-cycle corrector. The receiver uses(More)
