This paper presents a coupled finite element-boundary element approach in the time domain for the calculation of the dynamic response of structures due to dynamic excitations as arising from traffic or pile driving. The dynamic soil flexibility is calculated with a boundary element formulation in the frequency domain. It is transformed to a force-displacement relationship in the time domain and...

Multi-Context Systems (MCS) are a powerful framework to interlink heterogeneous knowledge bases under equilibrium semantics. Recent extensions of MCS to dynamic data settings either abstract from computing time, or abandon a dynamic equilibrium semantics. We thus present streaming MCS, which have a run-based semantics that accounts for asynchronous, distributed execution and supports obtaining ...

This paper presents a fully differential 1.2V 8-order inverter-based gm-C complex filter with 2.4MHz bandwidth and centered at 2.5MHz, designed in a 90nm CMOS process technology. Tuning is carried out through voltage controlled capacitors instead of transconductors, resulting in a significant improvement in terms of linearity. The filter presents attractive attributes in terms of power, IRR, SF...

This article describes two methods for controlling the surface of a liquid in an open container as it is being carried by a robot arm. Both methods make use of the fundamental mode of oscillation and damping of the liquid in the container as predicted from a boundary element model of the fluid. The first method uses an infinite impulse response filter to alter the acceleration profile so that t...

Dynamic Compaction (DC) is a common deep compaction method that is usually used for densification of coarse-grained soils. Although traditional continuum-based models such as the Finite Element Method can be successfully applied for assessment of stress distributions or deformations induced by DC, they are typically not adequate for capturing the grain scale mechanisms of soil behavior under im...

By means of the new mapping, we prove a strong convergence theorem for finding a common element of the se...

The paper describes a methodology for characterizing the signatures of targets for Imaging Infrared (IIR) missiles and generating dynamic missile engagement scenarios using MathWorks tools (primarily MATLAB and Simulink). The over-all objective of this work was to develop high fidelity physics-based simulations of the attack of IIR missiles on targets that are using various types of countermeas...
