Radiotherapy Technique for the Prostate Cancer Treatment: A Short Communication

Prostate cancer is the one of the most commonly diagnosed cancer among men throughout the world. In the recent days, prostate cancer can be managed by several options such as surgery, chemotherapy, radiotherapy, etc. Radiotherapy is considered as one of the popular options to treat prostate cancer due to excellent survival rate and fewer side effects. The field of radiotherapy is evolving since...

An efficient analytical solution for nonlinear vibrations of a parametrically excited beam

An efficient and accurate analytical solution is provided using the homotopy-Pade technique for the nonlinear vibration of parametrically excited cantilever beams. The model is based on the Euler-Bernoulli assumption and includes third order nonlinear terms arisen from the inertial and curvature nonlinearities. The Galerkin’s method is used to convert the equation of motion to a nonlinear ordin...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A Brief Introduction to Nonlinear Vibrations

Vibration phenomena that might be modelled well using linear vibration theory include small amplitude vibrations of long, slender objects like long bridges, aeroplane wings, and helicopter blades; small rocking motions of ships in calm waters; the simplest whirling motions of flexible shafts, and so on. However, interactions between bridges and foundations, between wings/blades and air, between...
