Rubber tubes in the sea.
A long tube with elastic walls containing water is immersed in the sea aligned in the direction of wave travel. The waves generate bulges that propagate at a speed determined by the distensibility of the tube. If the bulge speed is close to the phase velocity of the waves, there is a resonant transfer of energy from the sea wave to the bulge. At the end of the tube, useful energy can be extract...
متن کاملLiving cells as test tubes.
The combination of specific probes and advanced optical microscopy now allows quantitative probing of biochemical reactions in living cells. On selected systems, one can detect and track a particular protein with single-molecule sensitivity, nanometer spatial precision, and millisecond time resolution. Metabolites, usually difficult to detect, can be imaged and monitored in living cells with co...
متن کاملNine Test Tubes Generate any RE
In this paper we discuss how any recursively enumerable language can be generated using a distributed splicing system with a xed number of nine test tubes. This number has been recently reduced by other authors, and in this work we try to give an insightful algorithmic description of this kind of systems.
متن کاملTest Generation for the Binary Floating
The mathematical problem discussed is important for generating test cases in order to debug oating point adders designs. Floating point numbers are assumed to be written as strings of f0;1g bits, in a format compatible with IEEE standard 754. A mask is a string of characters, composed of f 0 0 0 ; 0 1 0 ; 0 x 0 g. A number and a mask are compatible if they have the same length and each numerica...
متن کاملFailure Probability and Remaining Life Assessment of Reheater Tubes
In this study, a real and significant industrial problem in a steam power plant was investigated. Reheater tubes in boilers are under the creep and the fireside corrosion mechanism that cause some of them to fail. Since the estimation of probability of failure (PoF) and remaining life (RL) is expensive and time consuming in the deterministic methods, in this work they were evaluated using struc...
