This paper studies the application of interval analysis and consistency techniques to ordinary di erential equations. It presents a unifying framework to extend traditional numerical techniques to intervals. In particular, it shows how to extend explicit methods to intervals. The paper also took a fresh look at the traditional problems encountered by interval techniques and studied how consiste...

Noise propagation through open windows of finite depth into an enclosure" (2010). Architectural Engineering-Faculty Publications. 100.

To protect fifteen northern European countries against sea level rise, a highly ambitious plan was put forward to build massive dams across the North Sea and English Channel, which will cut off from rest of Atlantic Ocean.

We deal with an efficient approach for the complete error control in scientific computing. For results obtained by standard numerical rou tines we provide in an additional validation step existence and enclosure of the corresponding solutions. The basic ideas of these methods are derived exemplary for nonlinear Volterra equations and then generalized to various initial value problems. We combin...

The low-frequency performance of a vented-box loudspeaker system is directly related ta a small number of easily measured system parameters. This system is a fourtharder (24-dB per octave cutoff) high-pass filter which can be adjusted ta have a wide variety of response characteristics. Enclosure lasses have a significant effect on system performance and should be taken into account when assessi...

Numerical simulation of shielding effectiveness (SE) of a perforated shielding enclosure is carried out, using the finite element method (FEM). Possibilities of model definitions and differences between 2D and 3D models are discussed. An important part of any simulation is verification of the model results—here the simulation result are verified in terms of convergence of the model in dependenc...
