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 -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
width.Comment: 12 pages, 15 eps figure files; minor modifications made and a few

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
