Reconstruction of the anthropogenically transformed environment in order to identify areas of historical environmental management requires a comprehensive analysis of multispectral data. It includes the construction of maps of vegetation indices ...

In this video, we introduce a real-time algorithm that computes gaze transition entropy. This approach can be employed in detecting higher level cognitive states such as situation awareness. We first compute fixations using our real-time version of a ...

We consider the problem of finding a set of alternative configurations of redundant complexes for onboard equipment and give an analytic solution. The redundancy problem is solved by finding admissible values of the "integration" matrix that contains ...

We consider a formalized problem setting for designing possible configurations of a technical system with redundant components and its analytic solution. As the quality criterion for a specific configuration we use the constancy of a given set of ...

Differential cryptanalysis is an effective tool in modern cryptanalysis. The differential chain of a Markov cipher forms a Markov chain, and the second largest eigenvalue SLE of the transition matrix determines the number of iterations such that the ...

Since the linear structure of linear feedback shift registers (LFSRs) has a drawback that may lead to attacks against LFSR-based stream ciphers, feedback with carry shift registers (FCSRs) have been proposed as an alternative to LFSRs for the design of ...

We consider the problem of inferring choices made by users based only on aggregate data containing the relative popularity of each item. We propose a framework that models the problem as that of inferring a Markov chain given a stationary distribution. ...

The vector autoregressive (VAR) model is a powerful tool in learning complex time series and has been exploited in many fields. The VAR model poses some unique challenges to researchers: On one hand, the dimensionality, introduced by incorporating ...

This paper addresses the controllability of context-sensitive probabilistic mix-valued logical control networks with constraints on states and controls. First, using the semi-tensor product of matrices, the context-sensitive probabilistic mix-valued ...

The paper introduces a two-step method of quantifying eye movement transitions between Areas of Interests (AOIs). First, individuals' gaze switching patterns, represented by fixated AOI sequences, are modeled as Markov chains. Second, Shannon's entropy ...

Identifying outlier objects against main community evolution trends is not only meaningful itself for the purpose of finding novel evolution behaviors, but also helpful for better understanding the mainstream of community evolution. With the definition ...

Eye tracking experiments are the state-of-the-art technique to study questions of usability of graphical interfaces. Visualizations help to analyse eye tracking data by presenting it in a graphical way. In this paper we contribute a new visualization ...

The study proposes a joint source channel decoding scheme with the speech source residual redundancy without changing the complexity of the decoding algorithm. As the speech parameter index could be used to calculate the transition probability of the ...

Nowadays, computer is already a common and important device that uses in all institution and use ICT for supporting the business or even as a business enabler. They always keep expanding their ICT to supporting their business in more ways. People need ...

Two methods to evaluate the state transition matrix are implemented and analyzed to verify the computational cost and the accuracy of both methods. This evaluation represents one of the highest computational costs on the artificial satellite orbit ...

In this study, an automatic birdsong recognition system based on syllable features was developed. In this system, after syllable segmentation, three syllable features, namely mean, QI and QE, were computed from the MFCCs of each syllable aims at ...

Credit rating is involved in many financial applications to estimate the creditworthiness of corporations or individuals. In addition to building accurate credit rating models, the stability of models is of significant importance to economic ...

DC-DC converters are nonlinear systems that can exhibit complicated phenomena, which make difficult the system behaviour analysis and the controller design. The validity of any prediction and analysis of the converter behaviour are, mainly, related to ...

Nowadays, teaching and learning process are changes drastically. Everything changes to be more digitalized and simpler. The way teacher addressing the materials, the way the student record the materials from the teacher, the way to communicate between ...

We propose a calibrated two-dimensional cellular automaton model to simulate pedestrian motion behavior. It is a v_max= 4 (3) model with exclusion statistics and random shuffled dynamics. The underlying regular grid structure results in a direction-...
