The Possible ‘Impossible’ Turn
Turning back after engine failure during the take off phase of flight in a single engine aircraft is examined using a simplified analytical model. The important parameters are identified. The analysis shows that the optimum flight path is teardrop shaped with a 45◦ bank angle at stall velocity during the turn. The effects of engine failure altitude, wind direction and velocity, and bank angle o...
متن کاملProving the Impossible is Impossible is Possible: Disproofs Based on Hereditary Partitions
A novel technique, ca l led heredi tary p a r t i t i o n s , is Introduced. I t permits the r igorous proof tha t , in a given axiomat izat ion, cer ta in states can never be reached. The technique is implemented in a computer program, DISPROVER, and is applied to robot wor lds. DISPROVER cooperates wi th a pathf ind ing program when the l a t t e r encounters d i f f i c u l t i e s .

متن کاملMaking an impossible mission possible.
Cardiovascular disease (CVD) is widespread in developing countries. Hypertension is a major contributor of CVD. Left ventricular hypertrophy (LVH) is a risk marker in hypertensive populations. Identification of LVH and treatment of high-risk patients can result in more effective use of the limited resources. LVH is diagnosed by echocardiography, often unavailable in developing countries. In Gam...
متن کاملPossible Dilemmas Raised by Impossible Moral Requirements
The priority that Tessman’s argument gives to phenomenological and neuropsychological explanations of moral requirements entails a fundamental shift in our understanding of these. Two central problems of normative theory come together in Tessman’s account. The first arises when an agent’s sense of requirement clashes with what a systematic theory prescribes. The second arises when neuropsycholo...
متن کاملImpossible and Possible Operations in Quantum Information
We prove a general limitation in quantum information that unifies the nocloning and no-complementing principles. We show that one cannot design Hadamard and unitary gates for creating equal and unequal superpositions of the original and its complement state. We show that if an unknown qubit is chosen from polar great circle then it is possible to design above logic gates. But qubits chosen from...
