Economic uses and substitution of non-ferrous metals and alloys

MUST commonly used non-ferrous metals at the present stage of industrialsation in India are aluminium, copper, zinc, lead and tin. These metals and their alloys form the basis of innumerable engineering appl-ications as well as domestic uses.Unfortunately, except aluminium and negligibly small quantity of copper, zinc and lead. India does not produce at present any of the other non-ferrous metals, Without going into the stati-stics of Fourth Five-Year Plan period demand and prod-uction figures for these metals which undoubtedly have been dealt in some other papers of this Symyosium, it is sufficient to point out that jointly these four non-ferrous metals cause an annul drainage of about rupees forty crores of' foreign exchange. Further, the anti-cipated production capacity of copper, zinc and lead in near future fall fat- short of anticipated demand. The situation regarding tin is still worse because uptil now no tin bearing ores have been found in India

Scalar sector properties of two-Higgs-doublet models with a global U(1) symmetry

We analyze the scalar sector properties of a general class of two-Higgs-doublet models which has a global U(1) symmetry in the quartic terms. We find constraints on the parameters of the potential from the considerations of unitarity of scattering amplitudes, the global stability of the potential and the $\rho$-parameter. We concentrate on the spectrum of the non-standard scalar masses in the decoupling limit which is preferred by the Higgs data at the LHC. We exhibit charged-Higgs induced contributions to the diphoton decay width of the 125\,GeV Higgs boson and its correlation with the corresponding $Z\gamma$ width.Comment: 12 pages, 15 eps figure files; minor modifications made and a few references adde

Controlled Natural Language Generation from a Multilingual FrameNet-based Grammar

This paper presents a currently bilingual but potentially multilingual FrameNet-based grammar library implemented in Grammatical Framework. The contribution of this paper is two-fold. First, it offers a methodological approach to automatically generate the grammar based on semantico-syntactic valence patterns extracted from FrameNet-annotated corpora. Second, it provides a proof of concept for two use cases illustrating how the acquired multilingual grammar can be exploited in different CNL applications in the domains of arts and tourism
