The truncation of stellar discs is not abrupt but characterized by a continuous distancing from the exponential profile. There exists a truncation curve, t(r), ending at a truncation radius, r t. We present here a theoretical model in which it is assumed that the magnetic hypothesis explaining the flat rotation curve also explains the truncation. Once stars are born, the centripetal magnetic fo...

‎In this paper‎, ‎we have investigated the chaotic behavior of thermal convection in couple stress liquid saturated porous layer subject to gravity‎, ‎heated from below and cooled from above‎, ‎based on theory of dynamical system‎. ‎A low dimensional Lorenz‎- ‎like model is obtained by using Galerkin-truncation approximation‎. ‎We found that there is proportional relation between scaled couple ...

Local grid refinement aims to optimise the relationship between accuracy of the results and number of grid nodes. In the context of the finite volume method no single local refinement criterion has been globally established as optimum for the selection of the control volumes to subdivide, since it is not easy to associate the discretisation error with an easily computable quantity in each contr...

Truncation artifacts occur in MR imaging because Fourier transforms are used to process MR signal data. These artifacts may alter the intensity, shape, and anatomic detail of structures in the spine. Ring artifacts (Gibb phenomenon) occurring near highly contrasting interfaces represent but one manifestation of truncation artifacts visible on MR images. We review truncation phenomena by providi...

Italian displays a rich variety of truncation patterns and therefore forms an ideal testing ground for the constraint interaction determining truncation in general. The goal of this paper is to describe the various truncation patterns of Italian and to define a set of constraints which, in their interaction, can capture the individual patterns. I will focus my attention on name truncation, whic...

‎in this paper, we formulate the fourth order sturm-liouville problem (fslp) as a lie group matrix differential equation. by solving this ma- trix differential equation by lie group magnus expansion, we compute the eigenvalues of the fslp. the magnus expansion is an infinite series of multiple integrals of lie brackets. the approximation is, in fact, the truncation of magnus expansion and a gauss...

When disyllabic words of Chinese are compounded, truncation often applies to yield a disyllabic output that draws one syllable from each of the contributing words, e.g., xiàdiē + fúdù → xiàdiē + fúdù → diēfú. A substantial portion of new words enter Chinese via this process, and all combinations of four underlying syllables are attested in disyllabic neologisms. Variation in which syllable of t...

Proficient Content Based Image Retrieval system is a much needed system for plenty of image retrieval supporting applications, which retrieve images more rapidly from giant image databases. Block Truncation Coding (BTC) is one of the prominent and simple techniques used most of the time. This method is built on color properties of an image for image retrieval. In this paper a novel Static Thepa...

Multipliers play a vital role in many cryptographic applications like elliptic curve cryptography, RSA and other algorithms. The direct truncation of least significant part of the product leads to large error in the resultant product when fixed width output is the requirement. This paper proposes a truncation error minimizing logic which greatly reduces truncation error. Truncation error minimi...

Truncation is a term, which defines cutting off the negligible contribution of the results of the fault tree/event tree analysis, when evaluating complex facilities. This paper shows that consideration of requirements from Probabilistic Risk Assessment Procedures Guide at the largest acceptable truncation may lead to more than 40% differences from the results with no truncation at results for F...
