We propose the notion of the oscillator on Kähler space and consider its supersymmetrization in the presence of a constant magnetic field. Supersymmetric mechanics attracts permanent interest since its introduction witten [1]. However, studies focussed mainly on the mechanics with standard N = 2 supersymmetries (see for the review sukh [2] and refs therein). The systems with N = 4 supersymmetri...

We present three lectures on heterotic M -theory and a fourth lecture extending this theory to more general orbifolds. In Lecture 1, Hořava-Witten theory is briefly discussed. We then compactify this theory on Calabi-Yau threefolds, choosing the “standard” embedding of the spin connection in the gauge connection. We derive, in detail, both the five-dimensional effective action and the associate...

Research in building robulst NLP systems with ambiguity resolution techniques has gained momentum in recent years. In particular, the anaphora resolution initiatives have reached unpreceented heights in last 10 years or so. Mitkov et. al (2001) have reported both rule based knowledge based approaches and machine learning based ‘knowledge poor’ approaches in an ACL issue devoted to this subject....

Asymptotical analysis of concatenated codes with EXIT charts [tB99] or the AMCA [HH02b] is proven to be a powerful tool for the design of power–efficient communication systems. But, usually the result of the asymptotical analysis is a binary decision, whether convergence of iterative decoding is possible at the chosen signal–to– noise ratio, or not. In this paper it is shown how to obtain the I...

Gruber (1996) finds evidence to support selection ability among active fund investors for equity funds listed in 1982. Using a large sample of equity funds, I find evidence that newly invested money is able to predict future fund performance, in that the equally weighted portfolios of funds that receive more money subsequently perform significantly better than those that lose money. There is no...

MAGEAD is a morphological analyzer and generator for the Arabic language family, by which we mean both Modern Standard Arabic (MSA) and the spoken dialects. MAGEAD explicitly addresses the need for processing the morphology of the dialects as well. Furthermore, MAGEAD can model both phonology and orthography explicitly. In this paper, we present in detail the morphophonemic and the orthographic...

thermoluminescence (tl) dating was established in oxford to fulfil the demand for dating ceramics and other heated man made products (aitken, 1985).  it determines the time elapsed since the mineral grains have been heated. following the establishment of tl dating method, it was used to date fired materials such as pottery, flint and etc. optically stimulated luminescence (osl) determines the t...
