The terrain classification is a very important subject to the all-terrain robotics community. The knowledge of the type of terrain allows a rover to deal with its environment more efficiently. The work presented in this paper shows that it is possible to differentiate terrains based on their aspects, using exteroceptive sensors, as well as based on their influence on the rover’s behavior, using...

Online algorithms have been successful at a variety of prediction tasks. In structured prediction settings, the model produced by an online learner is fed as input to some combinatorial algorithm for producing structured outputs. This combinatorial algorithm is predominantly considered a black box, which severely limits the control available to the learner. In this paper, we break open this bla...

Parathyroid hormone (PTH) regulates mineral metabolism and bone turnover by activating specific receptors located on osteoblastic and renal tubular cells and is fully functional as the N-terminal 1-34 fragment, PTH-(1-34). Previously, a "U-shaped" conformation with N- and C-terminal helices brought in close proximity by a turn has been postulated. The general acceptance of this hypothesis, desp...

Let G be a locally compact amenable group, TLIM ( ) the topological left-invariant means on , and 0 limit points of Følner-nets. I show that = unless is σ -compact non-unimodular, in which case ≠ . This improves 1970 result Chou 2009 Hindman Strauss. consider analogous problem for non-topological means, give short construction net converging to invariance “weakly but not strongly,” simplifying ...

The objective of this paper is to investigate the existence mild solutions and optimal controls for a class fractional neutral stochastic integrodifferential equations driven by Rosenblatt process Poisson jumps in Hilbert spaces. First we establish new set sufficient conditions aforementioned systems using successive approximation approach. results are formulated proved calculus, solution opera...

Recovering a function f from its integrals over hyperplanes (or line integrals in the two-dimensional case), that is, recovering f from the Radon transform Rf of f , is a basic problem with important applications in medical imaging such as computerized tomog-raphy (CT). In the presence of stochastic noise in the observed function Rf , we shall construct asymptotic uniform confidence regions for...

Those who study classiication theory, whether it be in the form of statistical pattern recognition, syntactical pattern recognition, or neural approaches to classiication are aware of the recent achievements and advances of their elds. For example names such as Bayes, Fisher, Wald, Fu, and Rosenblatt are well known for their pioneering contributions to classiication theory. However, few are awa...

The study of WWW-traffic measurements has shown that different traffic characteristics can be modeled by long-tail distributed random variables (r.v.s). In this paper we discuss the nonparametric estimation of the probability density function of long-tailed distributions. Two nonparametric estimates, a Parzen–Rosenblatt kernel estimate and a histogram with variable bin width called polygram, ar...

Nonparametric estimation for dependent observations has a long history in statistics. Rosenblatt [42] first studied density estimation for dependent data. Since then several authors have considered nonparametric estimation under various assumptions (notable early articles include Robinson [39] and Hart [29]). For example, Hall and Hart [25], Giraitis et al. [22], Mielniczuk [34] and Estevas and...

O presente artigo pretende analisar como os elementos essenciais à teoria do ficcional desenvolvida por Wolfgang Iser encontram-se formulados em esforços filosóficos de natureza epistemológica desenvolvidas pelos primeiro-românticos alemães. A partir análise e discussão das principais teses Der Akt des Lesens (1984) Das Fiktive und Imaginäre (2016), procedemos a um cotejo com as reflexões Noval...
