چکیده
The paper considers the natural oscillations of shell structures. In general, these structures are a set deformable elements with different rheological properties. An algorithm for solving viscoelastic dynamic problems has been developed complex axisymmetric physical properties structural described by linear Boltzmann-Voltaire relations integral difference cores. three-parameter core Rzhanitsyn-Koltunov was used as relaxation core. problem is reduced to systems first-order ordinary differential equations in variables. A frequency equation obtained, solution where Muller method applied. calculated values frequencies given degree accuracy given.

from 1950s onward, new theories and critical approaches burgeoned across humanities. these theories were context-oriented; as a result, the analysis of discursive practices gained significance. thus, social, political, historical and cultural discourses that have been hitherto marginalized and considered inferior to literary texts, were introduced as important texts to be analyzed by critics. o...
Opinion Mining: Taking into account the Criteria!
Today we are more and more provided with information expressing opinions about different topics. In the same way, the number of Web sites giving a global score, usually by counting the number of stars for instance, is also growing extensively and this kind of tools can be very useful for users interested by having a general idea. Nevertheless, sometimes the expressed score (e.g. the number of s...

Professor and author of correspondence, Phone: +33 2 51 85 83 00, Fax: +33 2 51 85 81 99, Email: [email protected]. ABSTRACT This paper discusses the utility of using simple stiffness and vibrations models, based on the Jacobian matrix of a manipulator and only the rigidity of the actuators, whenever its geometry is optimised. In many works, these simplified models are used to propose ...
