Renewable and Sustainable Energy Reviews | Year: 2015

Two popular policies for fostering electricity from renewable energy sources (RES-E) are FIT (feed-in tariffs) and RPS (renewable portfolio standards). Although it is essential for the government to intervene in the renewable energy market for a positive externality of RES-E, poorly designed market regulations can lead to excess profits for the renewable energy sector, which in turn increases policy costs. In addition, those who benefit from such regulations may actively seek rents. This paper explores the rents or windfall profits generated through RPS and FIT and furthermore, investigates which is more substantial for the case of South Korea, which has had experience with FIT and RPS over the past 10 years. According to the results, rents generated from RPS were bigger than those from FIT, except for solar PV in South Korea. Moreover, this study also investigates the policy design elements that could curb these rents. © 2015 Elsevier Ltd.

This paper presents the isotropic placement of optical mice for the velocity estimation of a mobile robot. It is assumed that optical mice are placed at the bottom of a mobile robot, with possible restriction on their installation. First, with the characteristic length introduced, the velocity kinematics of a mobile robot with an array of optical mice is obtained. Second, the geometrical conditions for the isotropic and singular optical mouse placements are derived, along with the optimal characteristic length. And, for an anisotropic optical mouse placement, the suboptimal characteristic length required for maximal isotropy is determined. Third, simulation results for several different placements of three optical mice are given: the optimal optical mouse placement and the least squares mobile robot velocity estimation. © 2013 IEEE.
