Conditional Excluded Middle without the Limit Assumption
But Lewis famously objects that counterfactually supposing that a given line had been more than an inch long will not yield an A-world minimally different from i. ‘‘Just as there is no shortest possible length above 1¢¢,’’ he writes, ‘‘so there is no closest world to ours among the worlds with lines more than an inch long’’ (1973a, 20–21; see also 1981b, 228–230). Lewis and Stalnaker also agree...

But Lewis famously objects that counterfactually supposing that a given line had been more than an inch long will not yield an A-world minimally different from i. “Just as there is no shortest possible length above 1′′,” he writes, “so there is no closest world to ours among the worlds with lines more than an inch long” (a, –; see also b, –). Lewis and Stalnaker also agree abo...
متن کاملFinite Time--Horizon Risk-Sensitive Control and the Robust Limit under a Quadratic Growth Assumption
The nite time{horizon risk sensitive limit problem for continuous, nonlinear systems is considered. Previous results are extended to cover more typical examples. In particular, the cost may grow quadratically, and the diiusion coeecient may depend on the state. It is shown that the risk sensitive value function is the solution of the corresponding dynamic programming equation. It is also shown ...
متن کاملReaching the betz limit experimentally and numerically
The Betz theory expresses that no horizontal axis wind turbine can extract more than 16/27 (59.3%) of the kinetic energy of the wind. The factor 16/27 (0.593) is known as the Betz limit. Horizontal Axis wind turbine designers try to improve the power performance to reach the Betz limit. Modern operational wind turbines achieve at peak 75% to 80% of the Betz limit. In 1919, Albert Betz used an a...
متن کاملTesting for the Unconfoundedness Assumption Using an Instrumental Assumption
The identification of average causal effects of a treatment in observational studies is typically based either on the unconfoundedness assumption (exogeneity of the treatment) or on the availability of an instrument. When available, instruments may also be used to test for the unconfoundedness assumption. In this paper, we present a set of assumptions on an instrumental variable which allows us...
