Tree adjoining grammars (TAGs) provide an ample tool to capture syntax of many Indian languages. Tamil represents a special challenge to computational formalisms as it has extensive agglutinative morphology and a comparatively difficult argument structure. Modelling Tamil syntax and morphology using TAG is an interesting problem which has not been in focus… (More)
This paper analyzes the existence of a Granger causality relationship between stock prices and trading volume using minute by minute data (transformed from tick by tick data) of Nifty 50 companies traded at the National Stock Exchange, India for the period of one year from July 2014 to June 2015. Since the time series data taken is not integrated in of the… (More)
This paper describes a method for the rapid isolation of phycobilisomes using a cationic detergent, CTAB (cetyltrimethylammonium bromide). The method has distinct advantages over those currently in use in that (i) release of intact phycobilisomes from cells in the presence of CTAB occurs in 40 s (as compared to 40-60 min of incubation required with Triton… (More)
ATP-sulphurylase from an unicellular blue-green alga, Spirulina platensis was localized in the soluble fractions of cell-free homogenate, and it was stable for over 3 weeks at -6 degrees C.
Tree adjoining grammar (TAG) is specifically suited for morph rich and agglutinated languages like Tamil due to its psycho linguistic features and parse time dependency and morph resolution. Though TAG and LTAG formalisms have been known for about 3 decades , efforts on designing TAG Syntax for Tamil have not been entirely successful due to the complexity… (More)
Tree adjoining Grammar (TAG) is a rich formalism for capturing syntax and some limited semantics of Natural languages. The XTAG project has contributed a very comprehensive TAG for English Language. Although TAGs have been proposed nearly 40 years ago by Joshi et al, 1975, their usage and application in the Indian Languages have been very rare,… (More)
