The invention relates to a method and a device for stabilising the flutter-prone edges of material webs guided with a free draw over rolls, especially paper webs in the dryer part of paper machines. The material web edge is protected from a disturbing flow around the material web edge by ...
However, to pursue acceptable computational efficiency, these studies mainly focus on a specific working state (i.e., a certain instant in the whole time domain) to evaluate the flutter failure risk. In fact, due to the load and boundary conditions of turbomachinery being time-variant with the...

Shell structures are some of the most widely used in engineering applications. Flat plates, stiffened panels, and wing ribs are each examples of components for which the design features may be dictated by the critical buckling load. Despite this practical significance, there exists only a handful ...

and lower winglet results in a combined center of gravity located at a reduced longitudinal offset to the torsional axis relative to the greater longitudinal offset for the single upper winglet and which advantageously minimizes the inertial effects of the winglet system on the flutter of the wing;...
In such calculations, the load parameters and the short-term extreme response can be treated as stochastic variables. The environmental contour method [19] is an efficient approach to estimate the long-term extreme response by a short-term extreme value analysis. This method decouples the ...
A method and apparatus for treating tachycardias are disclosed which utilize tachycardia cycle lengths in connection with selecting the type of antitachycardia pacing to be used in such treatment. A range of tachycardia cycle lengths is selected for which antitachycardia pacing treatment is indicated....
Complete control over the incubation times at each temperature is provided by a pump 12 and the ratio of tube length in each bath. Typical two-temperature PCR involves cycling a reaction mixture between about 60° C. and 95° C. with residence or incubation times in the range of 1-300 ...
A method of making a temporary medical electrical lead for pacing or defibrillating a heart of a patient. The method comprises providing at least one electrical conductor having proximal and distal ends; providing an insulating sheath formed of biocompatible material extending over and covering at ...
