In this paper we discuss the application of the certified reduced basis method and the associated software package rbMIT c © to “worked problems” in steady and unsteady conduction. Each worked problem is characterized by an input parameter vector — material properties, boundary conditions and sources, and geometry — and desired outputs — selected fluxes and temperatures. The methodology and ass...

This paper is an engineer-to-engineer note, to show a problematic point of long time DC measurements and show tips how to achieve higher accuracy there.. At long time measurements, rounding errors can seriously influence the output value. The problem is not just theoretical; our investigation is started because of a malfunctioning dilatation sensor system used at industrial turbines. We tried t...

EEMML (Emotional Eye Movement Markup Language) is a scripting tool that enables authors to describe and generate emotional eye movement in virtual agents. The EEMML is capable of describing and generating both basic eye movement and emotional eye movement, including primary (joy, sadness, anger, fear, disgust and surprise) and intermediate (emotions that can be represented as the mixture of two...

Non-stationary filtering of seismic data can be accomplished in time or in Fourier domain by the theory of non-stationary convolution (Margrave, 1998). Here I show the results of implementing this theory for time-variant filtering of seismic data with an arbitrary number of filters and for forward and inverse NMO correction in the frequency domain. In the first case I show that the filters may ...

Industry clusters have been the focus of scholars and governments since the second half of the 20th century. During a cluster’s growing process, the government plays an important role. In order to show the growing law of the clusters and how government did for co-agglomeration, we proposed two kinds of models: Logistic model and BA model with parameter α to describe the single and mass clusters...

When data are poor, we resort to theory modeling. This is a two-step process. We have first to identify the appropriate type of model for the system under consideration and then to tailor it to the specifics of the case. To understand settlement formation, which is the concern of this article, this involves choosing not only input parameter values such as site separations but also input functio...

The class of objects we consider are algebraic relations between the four kinds of classical Jacobi theta functions θj(z|τ), j = 1, . . . , 4, and their derivatives. We present an algorithm to prove such relations automatically where the function argument z is zero, but where the parameter τ in the upper half complex plane is arbitrary.

We introduce a model for the evolution of sexually transmitted diseases, in which the social behavior is incorporated as a determinant factor for the further propagation of the infection. The system may be regarded as a society of agents where in principle anyone can sexually interact with any other one in the population. Different social behaviors are reflected in a distribution of sexual atti...

This paper introduces a method for predicting the likely behaviors of continuous nonlinear systems in equilibrium in which the input values can vary. The method uses a parameterized equation model and a lower bound on the input joint density. to bound the likelihood that some behavior will occur, such as a state variable being inside a given numeric range. Using a bound on the density instead o...

This article considers continuous trajectories of the vector fields induced by primaldual potential-reduction algorithms for solving linear programming problems. It is known that these trajectories converge to the analytic center of the primal-dual optimal face. We establish that this convergence may be tangential to the central path, tangential to the optimal face, or in between, depending on ...
