Wiktionary Definition for: Entropy
cattag thermodynamics countable
#strictly '''thermodynamic entropy'''. A measure of the amount of energy in a physical system which cannot be used to do mechanical work.
#A measure of the disorder present in a system (now becoming obsolete in chemistry http://www.entropysite.com/ ).
#The capacity factor for thermal energy that is hidden with respect to temperature http://arxiv.org/pdf/physics/0004055 .
#The dispersal of energy; how much energy is spread out in a process, or how widely spread out it becomes, at a specific temperature. http://www.entropysite.com/students_approach.html
cattag statistics information theory countable A measure of the amount of information and noise present in a signal.
uncountable The tendency of a system that is left to itself to descend into chaos.
This white paper dissertation discusses the methods for efficiently approximating conditional probabilities in large domains by maximizing the entropy of the distribution given a set of constraints. The constraints are constructed from conditional probabilities, typically of low-order, that can be accurately computed from the training data. By appropriately choosing the...
Aggregate Industries UK began the process of achieving ISO 14001 in 1998, with the aim to have all 150 sites certified by 2001. To achieve this, they realized that a software solution would be the best way forward and Entropy International was approached. Aggregate Industries have integrated the Entropy System...
Assessment of normal and abnormal anatomical variability requires a coordinate system enabling inter-subject comparison. This paper presents a binary minimum entropy criterion to assess affine and nonrigid transformations bringing a group of subject scans into alignment. This measure is a data-driven measure allowing the identification of an intrinsic coordinate system...
This white paper presents a new watermark design tool for digital images and digital videos that are based on human visual system HVS characteristics. This tool has basic mechanisms of inhibitory and excitatory behaviors of HVS cells that are used to determine image dependent upper bound values on watermark insertion...
Each day companies face a more complex and changing environment that includes a chaotic, high-demanding market, competition with new, low-cost enterprises, well-informed and exigent stakeholders, and the ecommerce/ business/procurement explosion. This external entropy places executives in the center of an unpredictable and incomprehensible storm of events that makes companies quickly...
MOUNTAIN VIEW, Calif. -- New Release Powers Industry's First Entropy-Based IP Security Algorithms; Dramatic Speed Enhancements Drive Superior Price Performance
Barhale is a leading provider of civil engineering contracting and infrastructure services to blue chip clients, with four main UK regional operations. Barhale's needs were specific. They can have any number of sites operational at one time, being used for a few days or up to three years, and involving...
This document presents a statement of the calibration problem for multi-asset equity derivatives. It then illustrates a weighted Monte Carlo simulation (max-entropy and applies it to Arbitrage Pricing of Basket Options. The presentation then draws a comparison between WMC and Steepest Descent Method. Finally, it provides comments on correlation skew...
Magnetic resonance imaging of newborn infants with gestational age ranging from 24 to 40 weeks indicates major developmental changes in the human brain over this time period. Assessment of normal and abnormal anatomical variability requires a coordinate system enabling inter-subject comparison. This paper presents a method for identifying an intrinsic...
This paper proposes a novel non-Gaussian MRF for regularization of tensor fields for fiber tract enhancement. Two entities are considered in the model, namely, the linear component of the tensor, i.e., how much line-like the tensor is and the angle of the eigenvector associated to the largest eigenvalue. A novel,...
Macro Man submits: The second law of thermodynamics states that entropy always increases. Put another way, "things change." How one reacts to changing environments can often make the difference between long-term success and failure. Thursday's Olympic relay action clearly demonstrated the dangers of taking a cavalier approach to...
Adiabatic calorimetry at low temperature is the classical method for heat capacity measurement, from which many other thermodynamic properties such as enthalpy, entropy, and Gibbs free energy can be calculated. These data are of significance in theoretical study, application development, and industrial production of a compound. In the present paper,...
Every time an organizational change occurs, many processes may split in two, or three; a centralized sales organization suddenly is split into three business unit sales teams. The problem is that with organizational change, process management is very rarely factored into the overall event. Where organizational design drivers process management,...
Fed Bailout Rejected, Now What's Going To Happen?RE: Fed Bailout Rejected, Now What's Going To Happen?bailout was obviously a poor idea, you cannot spoon feed corporates who cannot look after themselves. They pay fancy salaries to their talentless managers & ceo's & if this is what they stand for they...
