Stable hovering of a jellyfish-like flying machine
Ornithopters, or flapping-wing aircraft, offer an alternative to helicopters in achieving manoeuvrability at small scales, although stabilizing such aerial vehicles remains a key challenge. Here, we present a hovering machine that achieves self-righting flight using flapping wings alone, without relying on additional aerodynamic surfaces and without feedback control. We design, construct and te...
متن کاملHoneybee: The flying pharmacist
Honeybee, a small -although powerful- creature moves from one place to another to make an elixir, which cures different diseases. To make one kilogram of honey the small creature has to carry 150000 pieces of pollen and suck the sap of ten million flowers.

متن کاملFaulty Conclusions
A case-control comparison of immunologic and psychological parameters in the multiple chemical sensitivity syndrome. This letter is prompted by Rall's editorial on media and science in the January issue of EHP (102:10). Rall implies that bad reporting is being conducted concerning dioxin, CFCs, and asbestos. Rall concludes by assuming that he is correct in assigning a high level of risk to each...
متن کاملOptimal Agreement Protocol in Malicious Faulty Processors and Faulty Links
adi it ion ally, the problems of Byzantine agreement, concensus, and interactive consistency are studied in a fully connected network with processors in malicious failure only. Such problems are re-examined with the assumption of malicious faults on both processors and links. The proposed protocols use the minimum number of message exchanges and can tolerate the maximum number of allowable faul...
متن کاملProve that a faulty multiplier is faulty ! ? Sandro
Formal verification of integer multipliers was an open problem for a long time as the size of any reduced ordered binary decision diagram (BDD) [1] which represents integer multiplication is exponential in the width of the operands [2]. In 1995, Bryant and Chen [4] introduced multiplicative binary moment diagrams (*BMD) which is a canonical data structure for pseudo Boolean functions allowing a...
