Interval Mathematics Applied to Critical Point Transitions
Interval Mathematics Applied to Critical Point Transitions
(2012-03-02)
The determination of critical points of mixtures is important for both practical and theoretical reasons in the modeling of phase behavior, especially at high pressure. The equations that describe the behavior of complex ...
Term Structure of Interest Rates
Term Structure of Interest Rates
(2012-03-02)
The risk free rate on bonds is a very important quantity that allows calculation of premium values on bonds. This quantity of stochastic nature has been modeled with different degrees of sophistication. This paper reviews ...
Comparison of Gap Interpolation Methodologies for water Level time Series using perl/pdl
Comparison of Gap Interpolation Methodologies for water Level time Series using perl/pdl
(2012-03-02)
Extensive time series of measurements are often essential to evaluate long term changes and averages such as tidal datums and sea level rises. As such, gaps in time series data restrict the type and extent of modeling and ...
The Combinatorial ANT System for Dynamic Combinatorial Optimization Problems
The Combinatorial ANT System for Dynamic Combinatorial Optimization Problems
(2012-03-22)
In this paper is presented a distributed algorithm based on Ant System concepts,called Combinatorial Ant System, to solve dynamic combinatorial optimization problems. Our approach consists of mapping the solution space of ...
Artificial Neural Network Predictions of Water Levels in a Gulf of Mexico Shallow Embayment
Artificial Neural Network Predictions of Water Levels in a Gulf of Mexico Shallow Embayment
(2012-03-01)
Tide tables are the method of choice for water level predictions in most coastal regions. However, for many locations along the coast of the Gulf of Mexico, tide tables do not meet United States National Ocean Service (NOS) ...

One of the most important subjects of interest, in nearly any human activity, is the perception of salary. It could even be said that the decision of following a career depends deeply on the perspective that the individual ...
One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters
One-Sided Confidence Interval Estimation for Weibull Shape and Scale Parameters
(2012-03-02)
In this paper, we consider the problem of one-sided conditional and unconditional interval estimation for the scale and shape parameters in a two-parameter Weibull model. The statistical inference is based upon the pivots ...
Program Implementation of the Rating Methods of Preference Ranking
Program Implementation of the Rating Methods of Preference Ranking
(2012-03-02)
Tide charts, based upon harmonic analysis, is the general method of choice for predicting water levels. In the shallow waters of the Gulf of Mexico, however, tide charts are woefully inadequate for the prediction of water ...
Scattering of e Polarized Whispering-Gallery mode from Concave Boundary
Scattering of e Polarized Whispering-Gallery mode from Concave Boundary
(2012-03-01)
In this work we present numerical results for the 2D problem of scattering E polarised whispering-gallery mode from concave convex perfectly conducting boundary. The results were obtained by applying the developed method ...
¿Como Trabajan las Calculadoras?
(2012-03-22)
What happens when you press the sine key on your calculator? How does a calculator quickly produce the values of trigonometric functions? For instance, how does the TI-89 calculate sin 1.0? You might be surprised to know ...
