La energía informacional de orden α y tipo β como criterio de comparación de sistemas de información difusa.

Julio Angel Pardo Llorente (1990)

Trabajos de Estadística

En este trabajo se establece un criterio de comparación entre sistemas de información difusa basado en la maximización de la energía informacional esperada de orden α y tipo β y se comprueba que verifica las propiedades más relevantes que a nuestro juicio debe verificar un criterio de comparación.

La medida de divergencia de Kagan en el muestreo secuencial con procesos de Dirichlet.

Domingo Morales González (1986)

Trabajos de Estadística

In this paper the Kagan divergence measure is extended in order to establish a measure of the information that a random sample gives about a Dirichlet process as a whole. After studying some of its properties, the expression obtained in sampling from the step n to the step n+1 is given, and its Bayesian properties are studied. We finish proving the good behaviour of a stopping rule defined on the basis of the information obtained in sampling when passing from a step to the following.

Large families of pseudorandom binary sequences and lattices by using the multiplicative inverse

Huaning Liu (2013)

Acta Arithmetica

Large families of pseudorandom binary sequences and lattices are constructed by using the multiplicative inverse and estimates of exponential sums in a finite field. Pseudorandom measures of binary sequences and lattices are studied.

Left MQQs whose left parastrophe is also quadratic

Simona Samardjiska, Danilo Gligoroski (2012)

Commentationes Mathematicae Universitatis Carolinae

A left quasigroup $(Q, q)$ of order $2^{w}$ that can be represented as a vector of Boolean functions of degree 2 is called a left multivariate quadratic quasigroup (LMQQ). For a given LMQQ there exists a left parastrophe operation $q_{∖}$ defined by: $q_{∖} (u, v) = w \Leftrightarrow q (u, w) = v$ that also defines a left multivariate quasigroup. However, in general, $(Q, q_{∖})$ is not quadratic. Even more, representing it in a symbolic form may require exponential time and space. In this work we investigate the problem of finding a subclass of LMQQs whose left parastrophe...

Limits of Bayesian decision related quantities of binomial asset price models

Wolfgang Stummer, Wei Lao (2012)

Kybernetika

We study Bayesian decision making based on observations $(X_{n, t} : t \in {0, \frac{T}{n}, 2 \frac{T}{n}, ..., n \frac{T}{n}})$ ( $T > 0, n \in ℕ$ ) of the discrete-time price dynamics of a financial asset, when the hypothesis a special $n$ -period binomial model and the alternative is a different $n$ -period binomial model. As the observation gaps tend to zero (i. e. $n \to \infty$ ), we obtain the limits of the corresponding Bayes risk as well as of the related Hellinger integrals and power divergences. Furthermore, we also give an example for the “non-commutativity” between Bayesian statistical and...

Linear spans of optimal sets of frequency hopping sequences

Gao Juntao, Hu Yupu, Li Xuelian (2012)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

Frequency hopping sequences sets are required in frequency hopping code division multiple access systems. For the anti-jamming purpose, frequency hopping sequences are required to have a large linear span. In this paper, by using a permutation polynomial δ(x) over a finite field, we transform several optimal sets of frequency hopping sequences with small linear span into ones with large linear span. The exact values of the linear span are presented by using the methods of counting the terms of the...

Local detection of defects from image sequences

Ewaryst Rafajłowicz, Marek Wnuk, Wojciech Rafajłowicz (2008)

International Journal of Applied Mathematics and Computer Science

Our aim is to discuss three approaches to the detection of defects in continuous production processes, which are based on local methods of processing image sequences. These approaches are motivated by and applicable to images of hot metals or other surfaces, which are uniform at a macroscopic level, when defects are not present. The first of them is based on the estimation of fractal dimensions of image cross-sections. The second and third approaches are compositions of known techniques, which are...
