Slender beams present interesting dynamic characteristics when they are curved according to a given shape. When the beam is curved according to one of its mode shapes, the natural frequency associated to that mode tends to increase significantly without affecting the other natural frequencies. It has...
Results for the frequency parameters are compared with results published in the literature. Modes of vibration are also included. The solution of the eigenproblem gives the eigenvalues of the system and their corresponding eigenvectors. The natural frequencies are the square root of the eigenvalues, ...

An analysis is presented of the effect of the value of the shear coefficient, k, on the first five natural frequency coefficients of Timoshenko beams. The study considers different combinations of boundary conditions: simply supported, simply supported-clamped, free-clamped, and clamped-clamped. ...

Natural frequencies of orthotropic rectangular plates with stepped thickness It is shown how one can derive an approximate formula for estimating a natural frequency of an orthotropic rectangular plate with stepped thickness by usin... T Sakata - 《Journal of Sound & Vibration》 被引量: 19发表: ...
(e.g. natural seismicity and construc- tion activity), and the fundamental differences between waves in plates and seismic surface waves, mean that one cannot simply conduct a frequency scaling of previous work in the kHz range and that the physics does not triv- ially translate to this new...
Python is widely used in natural language processing, so there are a couple of comprehensive open source libraries for this task, such as Google's CLD 2 and CLD 3, Langid, FastText, FastSpell, Simplemma and Langdetect. Unfortunately, most of them have two major drawbacks: Detection only work...
