Lyric Subjectivity, Ethics, Contemporary Poetics: Claudia Rankine, Fanny Howe, Elizabeth Robinson
… I consider select poems and poetics of Claudia Rankine, Fanny Howe, and Elizabeth Robinson, in order to argue that their postlanguage lyric poetry retains lyric subjectivity and reformulates it as ethical insofar as it is "circumspective" or "other-oriented"; that is, the lyric "I" is depicted …

Dynamic Model and Adaptive Control of a Transcritical Organic Rankine Cycle
The Transcritical Organic Rankine Cycle (TORC) is a non-linear time-varying heat recovery system for small-scale power generation. It is similar to a boiler-turbine system but uses organic fluid as the primary heat carrier instead of H2O and works in both subcritical and supercritical regions. The …

Wave energy converter design via a time-domain Rankine panel method
… consists of a time-domain three dimensional Rankine panel method coupled, in the time integration, with a MATLAB algorithm which solves for the equations of the gyroscope and Power Take-Off (PTO). The former acts as a force block, calculating the forces due to the waves on the hull, which is …
