The offer of standardized (or “standard offer”) commercial-sector energy efficiency incentives, based upon either energy saved or project cost, can underestimate the potential value of a given project to that customer. First, these incentives presume a single, up-front payment of project costs

Abstract The purpose of this research is to realize a small robot which can negotiate pipes whose diameter varies widely during the robot's course. A new in-pipe locomotion mechanism named "snaking drive" is proposed in this paper and its potential and fundamental characteristics

-tating discourse among teacher education faculty from which understandings of why, when, and how to use technology emerged. Several cases of situated practice are discussed with particular at-tention to how an understanding of meaningful technology use was negotiated through interac-tions between faculty
