Abstract: Earthquake fault rupture-soil-foundation interaction (FR-SFI) was simulated using the discrete element method (DEM) with irregularly shaped sphere-clusters to capture the three-dimensional nature of sand grains. High-performance ...

Abstract: The Dynamic Data System (DDS) methodology is used for the separation of the cutting signal from the dynamics of a dynamometer. A sixth order continuous Autoregressive Moving Average model is ...

Abstract: Cutting torque signals of a vertical milling machine are used for the analysis and identification of the machine tool system. The force signals are represented by stochastic differential equations ...

Abstract: Passive and active control have been performed on a flexible structure possessing complex modal behavior. Specifically, the structure has closely spaced modes which created a “beat phenomena” in ...

Abstract: This paper presents a discussion and the experimental proof-of-concept results of a novel ultrasonic testing (UT) method to identify the onset of delamination in reinforced concrete bridge decks. The novel UT method aims ...

Abstract: The writers have developed three inexpensive sealed-container sampling tools. Each of these novel tools allows the user to rapidly drill into a closed container, extract a sample of its contents (gas, liquid, or free-flowing ...

Abstract: Knowledge of the real-time behavior of a city would encourage making decisions in urban design in a dynamic way, adapting to what the city constantly needs, without further large periodic studies. This paper proposes a ...
