- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- non singular Morse-Smale flows, round handle decomposition, and link
- Language:
- English
- Description:
- We build the flows of non singular Morse-Smale systems on the 3-sphere from its round handle decomposition. We show the existence of flows corresponding to the same link of periodic orbits that are non equivalent. So, the link of periodic orbits is not in a 1-1 correspondence with this type of flows and we search for other topological invariants such as the associated dual graph.

- Language:

- Description:
- Let X be a Banach space of analytic functions on the open unit disk and Γ a subset of linear isometries on X. Sufficient conditions are given for non-supercyclicity of Γ. In particular, we show that the semigroup of linear isometries on the spaces S^{p} (p>1), the little Bloch space, and the group of surjective linear isometries on the big Bloch space are not supercyclic. Also, we observe that the groups of all surjective linear isometries on the Hardy space H^{p} or the Bergman space L_{a}^{p} (1< p< ∞,p\neq 2) are not supercyclic., Abbas Moradi, Karim Hedayatian, Bahram Khani Robati, Mohammad Ansari., and Obsahuje seznam literatury

- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Turing test, Loebner contest, strategy, and non-cooperation degree measure
- Language:
- Slovak
- Description:
- In this paper the idea of the Loebner contest as a practical implementation of the Turing test is presented. The Brian Plüss’ measure of the degrees of non-cooperation in a dialogue is applied to the dialogues of the Loebner contest. The proposal of a typology of non-cooperative features in the contest’s dialogues is discussed and the reliability of annotation with the use of this typology of features is analyzed. The degrees of non-cooperation of judges and programs for the Loebner contest (editions 2009 – 2012) are presented and discussed. On the basis of the results the role of a judge and the strategies used by programs are discussed for the contest and the Turing test., V tomto příspěvku je představena myšlenka soutěže Loebner jako praktické realizace Turingova testu. Míra míry nespolupráce Briana Plüssa v dialogu se vztahuje na dialogy soutěže Loebner. Diskutuje se o návrhu typologie nekooperativních prvků v dialogu soutěže a analyzuje se spolehlivost anotace s využitím této typologie prvků. Jsou prezentovány a diskutovány stupně nespolupráce soudců a programů pro soutěž Loebner (edice 2009 - 2012). Na základě výsledků se pro soutěž a Turingův test projednává role soudce a strategie používané programy., and Paweł Łupkowski

- Description:
- The aim of this paper is to open a new way of modelling non-exchangeable random variables with a class of Archimax copulas.

15876. Non-fragile controllers for a class of time-delay nonlinear systems
- Creator:
- Bakule, Lubomír and de la Sen, Manuel
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- decentralized control, large scale complex systems, nonlinear systems, continuous-time systems, and reduced-order systems
- Language:
- English
- Description:
- The paper deals with the synthesis of a non-fragile state controller with reduced design complexity for a class of continuous-time nonlinear delayed symmetric composite systems. Additive controller gain perturbations are considered. Both subsystems and interconnections include time-delays. A low-order control design system is first constructed. Then, stabilizing controllers with norm bounded gain uncertainties are designed for the control design system using linear matrix inequalities (LMIs) for both delay-independent and delay-dependent stability approaches. The main result shows that when such a non-fragile low-order controllers are implemented into each local controller of the decentralized controller for the global system, the global closed-loop systems are globally asymptotically stable.

15877. Non-fragile estimation for discrete-time T--S fuzzy systems with event-triggered protocol

- Type:

- Subject:
- robust optimization, Takagi-Sugeno fuzzy system, exponentially ultimately boundness, and non-fragile estimation
- Language:
- English
- Description:
- This paper investigates the non-fragile state estimation problem for a class of discrete-time T-S fuzzy systems with time-delays and multiple missing measurements under event-triggered mechanism. First of all, the plant is subject to the time-varying delays and the stochastic disturbances. Next, a random white sequence, the element of which obeys a general probabilistic distribution defined on [0,1], is utilized to formulate the occurrence of the missing measurements. Also, an event generator function is employed to regulate the transmission of data to save the precious energy. Then, a non-fragile state estimator is constructed to reflect the randomly occurring gain variations in the implementing process. By means of the Lyapunov-Krasovskii functional, the desired sufficient conditions are obtained such that the Takagi-Sugeno (T-S) fuzzy estimation error system is exponentially ultimately bounded in the mean square. And then the upper bound is minimized via the robust optimization technique and the estimator gain matrices can be calculated. Finally, a simulation example is utilized to demonstrate the effectiveness of the state estimation scheme proposed in this paper.

15878. Non-fragile sampled data H∞ filtering of general continous Markov jump linear systems
- Creator:
- Shen, Mouquan, Zhang, Guangming, Yuan, Yuhao, and Mei, Lei
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Markov jump linear system, sampled data H∞ filtering, and linear matrix equality
- Language:
- English
- Description:
- This paper is concerned with the non-fragile sampled data H∞ filtering problem for continuous Markov jump linear system with partly known transition probabilities (TPs). The filter gain is assumed to have additive variations and TPs are assumed to be known, uncertain with known bounds and completely unknown. The aim is to design a non-fragile H∞ filter to ensure both the robust stochastic stability and a prescribed level of H∞ performance for the filtering error dynamics. Sufficient conditions for the existence of such a filter are established in terms of linear matrix inequalities (LMIs). An example is provided to demonstrate the effectiveness of the proposed approach.

15879. Non-holonomic $(r,s,q)$-jets

- Tomáš, Jiří M.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- bundle functor, jet, non-holonomic jet, and Weil bundle
- Language:
- English
- Description:
- We generalize the concept of an $(r,s,q)$-jet to the concept of a non-holonomic $(r,s,q)$-jet. We define the composition of such objects and introduce a bundle functor ${\tilde{J}}^{r,s,q}\: \mathcal{F}\mathcal{M}_{k,l} \times \mathcal{F}\mathcal{M}$ defined on the product category of $(k,l)$-dimensional fibered manifolds with local fibered isomorphisms and the category of fibered manifolds with fibered maps. We give the description of such functors from the point of view of the theory of Weil functors. Further, we introduce a bundle functor $\tilde{J}^{r,s,q}_1\: 2\text{-}\mathcal{F}\mathcal{M}_{k,l} \rightarrow \mathcal{F}\mathcal{M}$ defined on the category of $2$-fibered manifolds with $\mathcal{F}\mathcal{M}_{k,l}$-underlying objects.

15880. Non-home: theoretical approach to migrants' dwellings

- Type:

- Subject:
- věda, domov, science, home, přistěhovalecké obydlí, ne-domov, ne-místo, migrants’ dwelling, non-home, non-place, 12, and 00
- Language:
- Czech
- Description:
- In this article we introduce the notion of non-home as an attempt of meaningful insight into the migrants’ dwelling constructed from elements of diff erent provenance (family homes, social housing institutions, etc.), depending on tenants housing experiences, defi nitions (knowledge) and the very materiality of a living space. In developing the idea of a non-home we refer to the theoretical concepts of non-places and heterotopias., V tomto článku představujeme pojem ne-domova jako pokus o smyslupný náhled do bydlení migrantů, jenž je zkonstruováno z prvků různé provenience (rodinné domovy, instituce sociálního bydlení apod.) v závislosti na obyvatelských zkušenostech nájemníků, defi nicích (vědění) a samotné materialitě prostoru obydlí. Při rozvíjení myšlenky ne-domova se odvoláváme na teoretické koncepty ne-míst a heterotopií., and Magdalena Łukasiuk, Marcin Jewdokimow.
