17482. Water as symbol: transformation and/or re-birth in the Indian anglophone novel
- Creator:

- Format:
- 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.

17483. Water surface topology of supercritical junction flow
- Creator:
- Rak , Gašper, Hočevar , Marko, and Steinman , Franci
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- junction, hydraulic experimention, standing wave, supercritical flow, and flow patterns
- Language:
- Slovak
- Description:
- The complexity of flow conditions at junctions amplifies significantly with supercritical flow. It is a pronounced three-dimensional two-phased flow phenomenon, where standing waves with non-stationary water surface are formed. To analyse the hydrodynamic conditions at an asymmetric right-angled junction with incoming supercritical flows at Froude numbers between 2 and 12, an experimental approach was used. For a phenomenological determination of the relations between the integral parameters of incoming flows and the characteristics of standing waves at the junction area, water surface topographies for 168 scenarios at the junction were measured using non-intrusive measurement techniques. The new, phenomenologically derived equations allow for determination of location, height and extent of the main standing waves at the junction. Research results give important information on the processes and their magnitude for engineering applications.

17484. 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.

17485. 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.

- 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.

17487. 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.

17489. Wavelet neural network as a multivariate calibration method in voltammetric electronic tongues
- Creator:
- Gutiérrez, J. M. , Moreno-Barón , L., del Valle, M., Leija, L., and Munoz, R.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Wavelet neural network, multivariate calibration, and electronic tongue
- Language:
- English
- Description:
- The paper presents a multi-output wavelet neural network (WNN) which, taking benefit of wavelets and neural networks, is able to accomplish data feature extraction and modeling. In this work, WNN is implemented with a feedforward one-hidden layer architecture, whose activation functions in its hidden layer neurons are wavelet functions, in our case, the first derivative of a Gaussian function. The network training is performed using a backpropagation algorithm, adjusting the connection weights along with the network parameters. This principle is applied to the simultaneous quantification of heavy metals present in liquid media, taking the cyclic voltammogram obtained with a modified epoxy-graphite composite sensor as departure information. The combination between processing tools and electrochemical sensors is already known as an electronic tongue.

17490. Wavelet oscillator neural networks for texture segmentation
- Creator:
- Sengur, Abdulkadir, Turkoglu , Ibrahim, and Ince, M. Cevdet
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- Wavewlet decomposition, wavelet oscillator neural networks, texture segmentation, and feature extraction
- Language:
- English
- Description:
- Texture can be defined as a local statistical pattern of texture primitives in observer's domain of interest. Texture analysis such as segmentation plays a critical role in machine vision and pattern recognition applications. The widely applied areas are industrial automation, biomedical image processing and remote sensing. This paper describes a novel system for texture segmentation. We call this system Wavelet Oscillator Neural Networks (WONN). The proposed system is composed of two parts. A second-order statistical wavelet co-occurrence features are the first part of the proposed system and an oscillator neural network is in the second part of the system. The performance of the proposed system is tested on various texture mosaic images. The results of the proposed system are found to be satisfactory.
