A straightforward inversion scheme (SIS) has been developed to interpret vertical electrical sounding data. This scheme does not require quasi-linearization of the inverse resistivity problem and thereby dispenses with the iterative process and the necessity of guessing the number of layers and their resistivities and thicknesses. The entire solution domain is divided into uniform thickness lay...

Most natural language processing tasks deal with large amounts of data, which takes a lot of time to process. For better results, a larger dataset and a good set of features are very helpful. But larger volumes of text and high dimensionality of features will mean slower performance. Thus, natural language processing and distributed computing are a good match. In the PAN 2013 competition, the t...

A straightforward synthetic methodology for the preparation of photochromic siloles based on dithienylethene motif is developed. It relies upon an efficient palladium-catalyzed annulation reaction a 2,3-bis(3-thienyl)-silirene with terminal alkynes in mild conditions. The functional group-tolerant and can be performed high yields variety alkynes. even extended to polymeric polypropargylmethacry...

An attempt is made to show in a straightforward way how a body-fixed frame may be constructed in classical and hence in quantum mechanics for a polyatomic molecule with the aid of which the vibration-rotation behavior of the molecule may be described.
