Use of Maximum Entropy Modeling in Wildlife Research
Tập 11 Số 4 - Trang 854-866
Maximum entropy (Maxent) modeling has great potential for identifying
distributions and habitat selection of wildlife given its reliance on only
presence locations. Recent studies indicate Maxent is relatively insensitive to
spatial errors associated with location data, requires few locations to
construct useful models, and performs better than other presence-only modeling
approaches. Further adva...
Vessel Pattern Knowledge Discovery from AIS Data: A Framework for Anomaly Detection and Route Prediction
Tập 15 Số 6 - Trang 2218-2245
Understanding maritime traffic patterns is key to Maritime Situational Awareness
applications, in particular, to classify and predict activities. Facilitated by
the recent build-up of terrestrial networks and satellite constellations of
Automatic Identification System (AIS) receivers, ship movement information is
becoming increasingly available, both in coastal areas and open waters. The
resulting...
Thermodynamics of Thermoelectric Phenomena and Applications
Tập 13 Số 8 - Trang 1481-1517
Fifty years ago, the optimization of thermoelectric devices was analyzed by
considering the relation between optimal performances and local entropy
production. Entropy is produced by the irreversible processes in thermoelectric
devices. If these processes could be eliminated, entropy production would be
reduced to zero, and the limiting Carnot efficiency or coefficient of
performance would be obta...
Optimal Multi-Level Thresholding Based on Maximum Tsallis Entropy via an Artificial Bee Colony Approach
Tập 13 Số 4 - Trang 841-859
This paper proposes a global multi-level thresholding method for image
segmentation. As a criterion for this, the traditional method uses the Shannon
entropy, originated from information theory, considering the gray level image
histogram as a probability distribution, while we applied the Tsallis entropy as
a general information theory entropy formalism. For the algorithm, we used the
artificial b...
Particle Swarm Optimisation: A Historical Review Up to the Current Developments
Tập 22 Số 3 - Trang 362
The Particle Swarm Optimisation (PSO) algorithm was inspired by the social and
biological behaviour of bird flocks searching for food sources. In this
nature-based algorithm, individuals are referred to as particles and fly through
the search space seeking for the global best position that minimises (or
maximises) a given problem. Today, PSO is one of the most well-known and widely
used swarm inte...
A Novel Hybrid Secure Image Encryption Based on Julia Set of Fractals and 3D Lorenz Chaotic Map
Tập 22 Số 3 - Trang 274
Chaos-based encryption schemes have attracted many researchers around the world
in the digital image security domain. Digital images can be secured using
existing chaotic maps, multiple chaotic maps, and several other hybrid dynamic
systems that enhance the non-linearity of digital images. The combined property
of confusion and diffusion was introduced by Claude Shannon which can be
employed for d...
Automatic Sleep Stages Classification Using EEG Entropy Features and Unsupervised Pattern Analysis Techniques
Tập 16 Số 12 - Trang 6573-6589
Sleep is a growing area of research interest in medicine and neuroscience.
Actually, one major concern is to find a correlation between several physiologic
variables and sleep stages. There is a scientific agreement on the
characteristics of the five stages of human sleep, based on EEG analysis.
Nevertheless, manual stage classification is still the most widely used
approach. This work proposes a ...
Statistical Properties of the Foreign Exchange Network at Different Time Scales: Evidence from Detrended Cross-Correlation Coefficient and Minimum Spanning Tree
Tập 15 Số 5 - Trang 1643-1662
We investigate the statistical properties of the foreign exchange (FX) network
at different time scales by two approaches, namely the methods of detrended
cross-correlation coefficient (DCCA coefficient) and minimum spanning tree
(MST). The daily FX rates of 44 major currencies in the period of 2007–2012 are
chosen as the empirical data. Based on the analysis of statistical properties of
cross-cor...
Bivariate Rainfall and Runoff Analysis Using Entropy and Copula Theories
Tập 14 Số 9 - Trang 1784-1812
Multivariate hydrologic frequency analysis has been widely studied using: (1)
commonly known joint distributions or copula functions with the assumption of
univariate variables being independently identically distributed (I.I.D.) random
variables; or (2) directly applying the entropy theory-based framework. However,
for the I.I.D. univariate random variable assumption, the univariate variable
may ...
Entropy Generation during Turbulent Flow of Zirconia-water and Other Nanofluids in a Square Cross Section Tube with a Constant Heat Flux
Tập 16 Số 11 - Trang 6116-6132
The entropy generation based on the second law of thermodynamics is investigated
for turbulent forced convection flow of ZrO2-water nanofluid through a square
pipe with constant wall heat flux. Effects of different particle concentrations,
inlet conditions and particle sizes on entropy generation of ZrO2-water
nanofluid are studied. Contributions from frictional and thermal entropy
generations are...
