11343. Water as symbol: transformation and/or re-birth in the Indian anglophone novel
- Creator:

- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Water, symbol, and Indian anglophone
- Language:
- English
- Description:
- This article deals with the Hindu cosmological imagery of water as presented in the Indian novel in English. The writers show a great interest in water as a means of depicting a transformation and/or re-birth of both the Indian society and the individuals in it relying on the water as symbolizing a beginning of a new life/identity in the Hindu cosmology. This is rendered vividly, for example, through the Nārada and Mārkandeya myths, where the two sages, after a passage through water, experience a new identity or a world perception totally different from that known to them before. R. K. Narayan, an author who lived all his life in India, deals in his novel The English Teacher with the spiritual transformation of the main character, Krishnan, which is accompanied and accomplished by different entities of water. He is oppressed both by the colonial condition and by personal tragedy, whereas Saleem, the main character of Salman Rushdie’s Midnight’s Children, who is made to represent the country, acquires in the jungle of the Sundarbans an understanding of the necessity of adopting elements of other cultures. Two other authors, Anita Desai and Chitra Banerjee Divakaruni, develop the theme of the woman’s condition as a representation of the counterpart and contradictory images of water and sun/fire. Desai’s Fasting, Feasting relates the Indian condition to that of another culture and Divakaruni’s The Mistress of Spices addresses the problems of the Indian concept of marriage in the diaspora while using mythological imageries of other cultures.

11344. Water turbine power control - feasible conception
- Creator:
- Němec, Zdeněk and Němec, Vojtěch
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- water power plant, water turbine, power control, and water turbine control
- Language:
- English
- Description:
- This paper is concerned with Francis water turbine power control issue. There are introduced six conceptions of power controllers and corresponding control loop features are discussed. The control features are illustrated with step responses and the major attention is paid to the undesirable under-control effect. On an example of control system with an elementary description and with relatively short turbine pipeline feeder are the control features compared. and Obsahuje seznam literatury

11345. Water-wave problem for a vertical shell
- Creator:
- Kuznetsov, Nikolay and Maz'ya, Vladimir
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- time-harmonic velocity potential, uniqueness theorem, Helmholtz equation, Neumann’s eigenvalue problem for Laplacian, integral equation method, and weighted Hölder spaces
- Language:
- English
- Description:
- The uniqueness theorem is proved for the linearized problem describing radiation and scattering of time-harmonic water waves by a vertical shell having an arbitrary horizontal cross-section. The uniqueness holds for all frequencies, and various locations of the shell are possible: surface-piercing, totally immersed and bottom-standing. A version of integral equation technique is outlined for finding a solution.

11346. Watson-Crick pushdown automata
- Creator:
- Chatterjee , Kingshuk and Ray, Kumar S.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- deterministic Watson-Crick automata, deterministic Watson-Crick pushdown automata, deterministic multi-head pushdown automata, and context free languages
- Language:
- English
- Description:
- A multi-head 1-way pushdown automaton with k heads is a pushdown automaton with k 1-way read heads on the input tape and a stack. It was previously shown that the deterministic variant of the model cannot accept all the context free languages. In this paper, we introduce a 2-tape, 2-head model namely Watson-Crick pushdown automata where the content of the second tape is determined using a complementarity relation, similar to Watson-Crick automata. We show computational powers of nondeterministic two-head pushdown automata and nondeterministic Watson-Crick pushdown automata are same. Moreover, deterministic Watson-Crick pushdown automata can accept all the context free languages.

11347. Wave probabilistic information power
- Creator:
- Svítek, Miroslav
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Wave probabilistic functions, wawe probabilistic circuits, wave information power, and quantum informatics
- Language:
- English
- Description:
- Paper summarizes the results in the area of information physics that is a new progressively developing field of study trying to introduce basics of information variables into physics. New parameters, like wave information flow, wave information/knowledge content or wave information impedance, are first defined and then represented by wave probabilistic functions. Next, relations between newly defined parameters are used to compute information power or to build wave information circuits covering feedbacks, etc.

11348. Wave probabilistic models
- Creator:
- Svítek, Miroslav
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Wave propability, quantization principle, complementary variables, mathematical statistics, and quantum mechanics
- Language:
- English
- Description:
- The paper presents the basic theory of wave probabilistic models together with their features. By introduction of the complementarity's principle between x-representation and k-representation the probability theory is completed for "structural" parameter which carries information about the changes of time series or random processes. The next feature of wave probabilistic models is the quantization principle or definition of probabilistic inclusion-exclusion rules.

11349. Wave probabilisties and quantum entanglement
- Creator:
- Svítek, Miroslav
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Probabilistic wave models, quantum system modeling, quantum informatics, entanglement, and pure and mixed quantum states
- Language:
- English
- Description:
- The paper continues with the theory of wave probabilistic models and uses the inclusion-exclusion rule to describe quantum entanglement as a wave probabilities resonance principle. The achieved results are mathematically described and an illustrative example is shown to demonstrate the possible applications of the presented theory.

- Subject:

- Language:
- English
- Description:
- This paper presents the results of the application of wavelet decomposition to processing data from the GGP sites (The Global Geodynamics Project). The GGP is an international project within which the Earth's gravity field changes are recorded with high accuracy at a number of stations worldwide using superconducting gravimeters. Data with a 5-second sampling interval from Wettzell and Bad Homburg were used for the research. The wavelet transform enables the investigation of the temporal changes of the oscillation amplitudes or the decomposition of the time series for the analysis of the required frequencies. The wavelet decomposition was performed using the regular orthogonal symmetric Meyer wavelet. The research concerned data from an earthquake period recorded at various locations and a quiet period when the gravimeters worked without any disturbances. The decomposition was followed by the Fast Fourier Transform for signal frequency components and then by correlation analyses of corresponding frequency components (for periods from 10 to 60 000 seconds) for all sensor combinations, for the quiet and the earthquake periods separately. Frequency components defining long term changes for all sensor combinations, as well as combinations between two sensors at the same site for the quiet days are characterised by high correlation coefficients. For the time of the earthquake, the Wettzell site data proved strong correlation for all frequency components, while the Bad Homburg site data showed an unexpected decrease of correlation for the majority of frequency components. The authors also showed that wavelet decomposition can be a good method of data interpolation, especially from the time of earthquakes. Moreover, it is a very useful tool for filtering the data and removing the noises., Janusz Bogusz, Anna Klos and Wieslaw Kosek., and Obsahuje bibliografii
