چکیده

In this paper we consider the following problems: (1) computing projections with distinct x-coordinates, (2) computing non-collinear projections, (3) computing non-cocircular projections, and (4) computing projections with non-parallel line segments. Here the word projection means perspective projection, a kind of projection that has received little attention in computational geometry. These problems are relevant to non-degeneracy assumptions and to the robustness of geometric algorithms .

Level of Grammatical Proficiency and Acquisition of Functional Projections: The case of Iranian learners of English language

Unlike Lexical Projections, Functional Projections (Extended Projections) are more of an ‘abstract’ in nature. Therefore, Functional Projections seem to be acquired later than Lexical Projections by the L2 learners. The present study investigates Iranian L2 learners’ acquisition of English Extended Projections taking into account their level of grammatical proficiency. Specifically, the aim is ...

m-Projections involving Minkowski inverse and range symmetric property in Minkowski space

In this paper we study the impact of Minkowski metric matrix on a projection in the Minkowski Space M along with their basic algebraic and geometric properties.The relation between the m-projections and the Minkowski inverse of a matrix A in the minkowski space M is derived. In the remaining portion commutativity of Minkowski inverse in Minkowski Space M is analyzed in terms of m-projections as...

A model based, anatomy dependent method for ultra-fast creation of primary SPECT projections

  Introduction: Monte Carlo (MC) is the most common method for simulating virtual SPECT projections. It is useful for optimizing procedures, evaluating correction algorithms and more recently image reconstruction as a forward projector in iterative algorithms; however, the main drawback of MC is its long run time. We introduced a model based method considering the eff...

Effects of electron-phonon interaction on transport through carbon nanotubes: lifting of degeneracies in Fock-space

In this contribution we present a brief overview of recent results about the effects of electron-phonon interaction in electronic transport through metallic single-walled carbon nanotubes. In particular, we present an electron-phonon-induced backscattering mechanism which can be seen as the removal of degeneracies in the electron-phonon Fock space. This mechanism, which is activated when drivin...
