Computerized vision, E-commerce and Missing Data Matrix
In the case of a missing data matrix, factorization can be solved by the alternation technique. This strategy could be useful to calculate the Structure from Motion (SFM), a common problem in computerized vision. The autor of this thesis proposes other uses of the...
The fBm process with reflection in the study of fluid networks
Fractional Brownian motion process (fBm) plays a very important role in the construction of stochastic models (mathematical models for situations in which randomness is present and that evolve in time) that properly describe some kind of phenomenon, like...
The undesired noise in digital communication distort the message that is transmitted, so scientists study how to improve the channel codes, a mathematical tool that allows to detect and to correct the mistakes ocurred in the transmission of information. UAB researchers have just defined new codes of channel that allow to obtain better parameters...
The splendor of century XVII also lighted on the queen of sciences: the mathematics. In this sense, a crucial point was the publication of Viète's work: In Artem Analyticen Isagoge, in 1591 . The algebraic procedures of Viète were the guide to solve geometric problems. Pietro Mengoli used these innovations to solve the quadratures of...
