Refracting profiles and generalized holodiagrams
The recently developed concept of refracting profiles and that of refraction
holodiagrams are combined so that the classical Abramson holodiagrams can be
generalized taking into account a wider class of wave fronts and refraction at
an interface, whenever regions of caustics are avoided. These holodiagrams are
obtained as envelopes of specific families of Cartesian Ovals with an
appropriate parametrization. Classical and reflecting holodiagrams are
particular cases of this class. Several of the properties of the classical
holodiagrams are shared by their richer generalized versionsComment: 12 pages, 7 figure
Clean Economy Rising: Manufacturing Powers Clean Energy in Ohio
Ohio has built upon its rich manufacturing legacy to become a leader in the production of wind, solar, and industrial energy efficiency technologies. Until recently, state and federal policies also spurred renewable energy projects throughout Ohio. Uncertainty over the future of these measures is dampening investment. This brief explores the drivers of Ohio's clean energy economy and the choices the state faces about its future competitiveness in the industry
