PLAXIS 2D and 3D are very specific perpetual software packages specifically intended for the analysis of deformation and stability in geotechnical engineering projects. Geotechnical applications require advanced constitutive models for the simulation of the non-linear and time-dependent behaviour of soils. PLAXIS is equipped with special features to deal with the numerous aspects of complex geotechnical structures.

Tholpavakoothu is a form of shadow puppetry that is practised in Kerala, India. It is performed using leather puppets as a ritual dedicated to Bhadrakali. This art form is especially popular in the Palakkad, Thrissur and Malappuram districts of Kerala. Each puppet is of an average height of 80 cms and is cut out in different postures. The puppets are arranged behind a long white curtain stretched across the Koothumadom. Behind this, on a split bamboo pole, is placed a row of wick lamps burning inside coconut halves.
A brief exposition of fractional order operators and their properties is given. Further, the effectiveness of fractional calculus in dynamical system behaviour is illustrated by an example. Finally, the illposedness of the fractional inverse problems and their regularized solution are analysed.
