Algebraic hyperstructures theory is a natural extension of the classical algebraic structures. Because of importance and new viewpoints in this theory, we try to apply this theory to the elementary particle physics and nuclear physics presenting the definitions and the concepts of the algebraic hyperstructures. In this work we intend to use this new branch of mathematics to describe the inte...
in this paper we study necessary and sufficient conditions for some types of linear combinations of wave packet frames to be a frame for l^2(r^d). further, we illustrate our results with some examples and applications.
we investigate the problem of the existence of a frame forright ideals of a c*-algebra a, without the use of the kasparov stabilizationtheorem. we show that this property can not characterize a as a c*-algebraof compact operators.
Concentrically braced frames (CBFs) are one of the efficient lateral load resisting systems in high seismicity regions. One of the common problems with the use of concentrically braced frames is limitation in the architectural application and position of the openings. Two-story X braced frames have more advantages than other configurations of concentrically braced frames, since in many cases th...
Title of dissertation: GABOR FRAMES FOR QUASICRYSTALS AND K-THEORY Michael Kreisel, Doctor of Philosophy, 2015 Dissertation directed by: Professor Jonathan Rosenberg Department of Mathematics We study the connection between Gabor frames for quasicrystals, the topology of the hull ΩΛ of a quasicrystal Λ and the K-theory of an associated twisted groupoid algebra. In particular, we construct a fin...
the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...
Vision is a primary sense that allows human beings to interact with their environment and motion is one of the most important cues that vision can explore and utilize. In this thesis, we present computational approaches to the problems of inferring three-dimensional motion information and perceiving two-dimensional human motions from a sequence of images captured by a camera. The three-dimensio...
The tensor product is the fundemental ingredient for extending one-dimensional techniques of filtering and compression in signal preprocessing to higher dimensions. Woven frames play a crucial role in signal preprocessing and distributed data processing. Motivated by these facts, we have investigated the tensor product of woven frames and presented some of their properties. Besides...
lthough fuzzy set theory and sheaf theory have been developed and studied independently, ulrich hohle shows that a large part of fuzzy set theory is in fact a subfield of sheaf theory. many authors have studied mathematical structures, in particular, algebraic structures, in both categories of these generalized (multi)sets. using hohle's idea, we show that for a (universal) algebra $a$, th...
On Transitive Consistency for Linear Invertible Transformations between Euclidean Coordinate Systems
Transitive consistency is an intrinsic property for collections of linear invertible transformations between Euclidean coordinate frames. In practice, when the transformations are estimated from data, this property is lacking. This work addresses the problem of synchronizing transformations that are not transitively consistent. Once the transformations have been synchronized, they satisfy the t...
