In this paper, stator resistance and speed estimation for a vector controlled induction motor drive taking saturation into account is presented. A mathematical dynamic model of an induction motor as influenced by magnetic circuit saturation is presented. Moreover, a modified structure of indirect vector controller scheme is proposed which involves the saturated value of the magnetizing inductan...
Let $R = bigoplus_{n in mathbb{N}_{0}} R_{n}$ be a standardgraded ring, $M$ be a finitely generated graded $R$-module and $J$be a homogenous ideal of $R$. In this paper we study the gradedstructure of the $i$-th local cohomology module of $M$ defined by apair of ideals $(R_{+},J)$, i.e. $H^{i}_{R_{+},J}(M)$. Moreprecisely, we discuss finiteness property and vanishing of thegraded components $H^...
Cultured human lymphocytes exposed to very low doses of X-rays become less susceptible to subsequent higher doses of X-rays. Cells exposed to doses as low as 0.5 rad (cGy) or 1 rad of X-rays at 32-34 h of culture become adapted so that less cytogenetic damage in the form of chromosome breakage is induced by 150 rad administered at 48 h. This response, which does not occur after high initial dos...
We introduce the concepts of lifting modules and (quasi-)discrete modules relative to a given left module. We also introduce the notion of SSRS-modules. It is shown that (1) if M is an amply supplementedmodule and 0→N ′ →N →N ′′ → 0 an exact sequence, then M isN-lifting if and only if it isN ′-lifting andN ′′-lifting; (2) ifM is a Noetherianmodule, then M is lifting if and only if M is R-liftin...
We investigate the figure rotation of dark matter halos identified in ΛCDM simulations. We find that when strict criteria are used to select suitable halos for study, 5 of the 222 halos identified in our z=0 simulation output undergo coherent figure rotation over a 5 h Gyr period. We discuss the effects of varying the selection criteria and find that pattern speeds for a much larger fraction of...
Let %‘A be the category of finite dimensional right modules for a quasi-hereditary algebra A. In the context of various types of Kazhdan-Lusztig theories, we study both the homological dual A! = Extt, (A/ rad(A), A/ rad(A)) and the graded algebra grA = @rad(A)j/rad(A)j+‘. For example, we investigate a condition introduced in [6], and here called (SKL’), which guarantees that A!’ E gr A. A stren...
The FERMl system, performing acquisition and DSP of calorimeter data in high energy collision experiments, planned at the LHC collider (CEW, Geneva, CH) is briefly overviewed. The system relies mainly upon the FERMI module, a dedicated VLSI multi-chip device per orming immediate neighbourhood of the collider itserJ; requiring rad-hard features. The issues for a system which absolutely requires ...
let m be an artinian module over the commutative ring a (with nonzero identity) and a p spec a be such that a is a finitely generated ideal of a and am = m. also suppose that h = h where h. = m/ (0: a )for i
DNA protein cross-links (DPC), DNA interstrand cross-links (ISCL), and DNA single strand breaks following treatment of experimental ovarian tumor cells (O-342) with five new metal complexes (three platinum, one titanium, one ruthenium compounds) were investigated at 6, 24, and 48 h after drug exposure and compared with their in vitro growth inhibitory potential. cis-Diamminedichloroplatinum(II)...
