Projective tensor products of approximation spaces associated with positive operators
Researches in MathematicsIn this paper the projective tensor products of approximation spaces associated with positive operators in Banach spaces are characterized. We show that the tensor products of approximation spaces can be considered as the interpolation spaces generated ...

Topological Complexity and LS-Category of Certain Manifolds
Journal of Mathematics, 2023 The Lusternik–Schnirelmann category and topological complexity are important invariants of topological spaces. In this paper, we calculate the Lusternik–Schnirelmann category and topological complexity of products of real projective spaces and their ...

Accounts of Chemical Research, 2015 One of the simplest questions that can be asked about molecular diversity is how many organic molecules are possible in total? To answer this question, my research group has computationally enumerated all possible organic molecules up to a certain size to gain an unbiased insight into the entire chemical space. Our latest database, GDB-17, contains 166.

Projections of a learning space. [PDF]
, 2013 Any subset Q' of the domain Q of a learning space defines a projection of that learning space on Q' which is itself a learning space consistent with the original one. Moreover, such a construction defines a partition of Q having each of its classes defining a learning space also consistent with the original learning space.

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose To evaluate the impact of various noise reduction algorithms and template matching parameters on the accuracy of markerless tumor tracking (MTT) using dual‐energy (DE) imaging. Methods A Varian TrueBeam linear accelerator was used to acquire a series of alternating 60 and 120 kVp images (over a 180° arc) using fast kV switching, on ...

, 2008 We describe a construction of fuzzy spaces which approximate projective toric varieties. The construction uses the canonical embedding of such varieties into a complex projective space: The algebra of fuzzy functions on a toric variety is obtained by a ...

Categories of projective spaces
Journal of Pure and Applied Algebra, 1996 AbstractStarting with an abelian category A, a natural construction produces a category PA such that, when A is an abelian category of vector spaces, PA is the corresponding category of projective spaces. The process of forming the category PA destroys abelianess, but not completely, and the precise measure of what remains of it gives the possibility ...

Digital radiography image quality evaluation using various phantoms and software
Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Purpose To investigate the effect of the exposure parameters on image quality (IQ) metrics of phantom images, obtained automatically using software or from visual evaluation. Methods Three commercial phantoms and a homemade phantom constructed according to the instructions given in the IAEA Human Health Series No.

Differentiable mapping of affine Qm and projective Pn spaces (m
Известия Томского политехнического университета: Инжиниринг георесурсов, 2009 It is proved that affine space mapping into manifolds of degenerate and non degenerate null-pairs of projective space are determined in invariant way by affine and projective spaces mapping.
