Ill-posed inverse problems of the form y = Xp where y is J-dimensional vector of a data, p is m-dimensional probability vector which can not be measured directly and matrix X of observable variables is a known J ×m matrix, J < m, are frequently solved by Shannon’s entropy maximization (MaxEnt, ME). Several axiomatizations were proposed (see for instance [1], [2], [3], [4], [5], [6], [7], [8], a...
In this paper we analyze certain aspects of virtual black holes. We see how quantum bubble is the representative of creation and annihilation of a pair of virtual black holes that satisfy the Wheeler-DeWitt equation. We calculate the loss of quantum coherence due to these virtual black holes and also see how these virtual black holes give space-time an intrinsic entropy.
Introduction: With age increases, the risk of cancer increases, and the importance of examining important sources of adjustment, including a sense of coherence, physical function, and social support to control the living conditions of these people, is of particular importance. Therefore, the present study was conducted to determine the relationship between a sense of coherence and physical func...
the polarimetric entropy and the alpha angle are two important parameters for analyzing polarimetric synthetic aperture radar data. they demonstrate the degree of randomness in the polarization of the received signal and scattering mechanism of scatterers respectively. recently, there has been an increasing interest in compact polarimetry due to its advantages in comparison with full polarimetr...
In signal analysis and synthesis, linear approximation theory considers a linear decomposition of any given signal in a set of atoms, collected into a so-called dictionary. Relevant sparse representations are obtained by relaxing the orthogonality condition of the atoms, yielding overcomplete dictionaries with an extended number of atoms. More generally than the linear decomposition, overcomple...
Buildings play a key role in organization and arrangement of city appearance. Specially, their facades have profound impact on the quality of urban landscapes while playing an important role in assessing urban environments by citizens. The introduction of superior building facades in terms of popular preferences is mostly based on visual elements of building facades. Furthermore, aesthetic pref...
In this paper we consider conditional prevision assessments on random quantities with finite set of possible values. After some preliminaries, we give the notions of generalized coherence and total coherence for imprecise conditional prevision assessments on finite families of conditional random quantities. Then, we examine some results on total coherence of such conditional previsions under di...
Evaluation plays an important role in interactive question answering systems like many computational linguistics fields. The coherence between the questions and the answers exchanged between the user and the system is one of the important criteria in evaluating these systems. In this paper, a new approach to determine the degree of coherence of generated text by the IQA systems is presented. Th...
Introduction: Ensuring an adequate Depth of Anesthesia (DOA) during surgery is essential for anesthesiologists. Since the effect of anesthetic drugs is on the central nervous system, brain signals such as Electroencephalogram (EEG) can be used for DOA estimation. Anesthesia can interfere among brain regions, so the relationship among different areas can be a key factor in the anesthetic process...
