Generic unpacking using entropy analysis
2010 5th International Conference on Malicious and Unwanted Software, 2010Malwares attempt to evade AV scanners using various obfuscation techniques. Packing is a popular obfuscation technique used by 80% of malwares. In this paper, we propose a generic unpacking mechanism to find the original entry point (OEP) using entropy analysis.

Generalized entropy production analysis for mechanism reduction
Combustion Theory and Modelling, 2018This paper introduces a generalized formulation for the entropy production analysis. The use of relations valid under the hypothesis of validity of the principle of detailed balance, that is violated in the remarkable case of irreversible reactions, is avoided by using more general expressions for the entropy generation due to the chemical reactions ...

Entropy generation analysis of different solar thermal systems
Environmental Science and Pollution Research, 2020The entropy generation analysis is an approach to optimize the performance of different thermal systems by investigating the related irreversibilities of the system. This paper provides a concise review of the entropy generation analysis performed for different solar thermal energy systems including solar collectors, solar heaters, solar heat ...

Journal of Mathematical Physics, 2002
The generalization à la Kolmogorov of Tsallis entropy, introduced by the authors in a previous work [J. Math. Phys. 37, 4480 (1996)], is revisited. Invariance properties are pointed out under weaker conditions than before. This result leads us to wonder if Tsallis entropy at the Kolmogorov abstraction level brings new information with respect to the ...

Entropy Generation Analysis of Microchannel Heat
Volume 9: Heat Transfer, Fluid Flows, and Thermal Systems, Parts A, B and C, 2009Analytical solutions for entropy generation rate distribution associated with heat transfer and fluid friction in microchannel heat sinks are examined. Microchannel heat sinks are modeled as a porous medium through which fluid flows. Analytical solutions are obtained by using velocity and temperature distributions of microchannel heat sinks, which are ...

Landslide Stability Analysis Based on Generalized Information Entropy
2009 International Conference on Environmental Science and Information Application Technology, 2009Landslide is a kind of serious geologic disaster. In the viewpoint of system theory, the landslides may be regarded as a nonlinear open system, and they are ceaselessly exchanging information and energy with their surrounding environment and inside of themselves.

On an extension problem, generalized fourier analysis, and an entropy formula
Integral Equations and Operator Theory, 1980Let h(t) be an n × n matrix valued function on the interval |t| ⩽ τ with summable entries. Let ĥ denote the Fourier transform of h and let e denote the n × n identity matrix. Necessary and sufficient conditions for the existence of an extension u of h to the full line such that e-u admits either a left or a right canonical factorization and the inverse

Analysis of Entropy Generation Mechanisms in a Desiccant Wheel
This work presents a novel detailed analysis of entropy generation mechanisms in a desiccant wheel (DW) by the the direct method, enabling differentiation of entropy sources by type and location. A detailed model of the desiccant-based system, implemented in Modelica, is used to compute entropy generation from various phenomena.Segura Schreiber, Jan +2 more

Analysis of Entropy Generation in Annular Porous Duct
Transport in Porous Media, 2015This paper presents an analytical solution of the velocity and temperature fields in terms of the modified Bessel functions by including the viscous as well as the Darcy dissipations of a fully developed viscous and incompressible fluid, flowing between horizontal concentric annular ducts filled with a saturated porous medium.
