Over the past decade improvements in semiconductor technology have led to faster power electronic switches with higher ratings. These devices have been used to improve the performance of various power converter systems. In particular, the Voltage Source Converter (VSC) has been widely used in...
Simulation is often used to model production processes with the aim of understanding and improving them. In many cases, however, information produced by simulation is not detailed enough and can be misinterpreted. The use of visualization in combination with simulation can provide project...
This research focuses on the accounts payable function in construction firms. The cash conversion cycle includes accounts payable and accounts receivable support functions. Research objectives focus on mapping the existing accounts payable processes in construction, building a model to represent...
This study presents the nonlinear design of a state space controller to control hydraulic actuators under displacement control, specifically for real-time pseudo-dynamic testing applications. The proposed control design process uses the nonlinear state space model of the dynamics of the system to...
Computational simulations of a perturbed vortex ring are performed to recreate and understand the instability seen in impacting water droplet experiments. Three initial conditions are tried to respectively trigger a Widnall instability, a Rayleigh centrifugal instability, and a vortex breakdown...
Heterogeneity of surfaces is often included in mathematical treatments of colloid transport and deposition as an afterthought, if at all. Most previous models of colloid transport and deposition have employed idealizations and simplifications such as assuming smooth collector surfaces with...
Fault detection methods have become an important tool in the prevention of safety and reliability issues for industrial rotating machines. Faults in these machines often develop progressively and are not easily observed under operating conditions until severe damage has occurred and further...
Reservoir and geomechanical coupled simulation of CO2 sequestration and enhanced coalbed methane recoveryDownload
Coalbeds are an extremely complicated porous medium with characteristics of heterogeneity, dual porosity and stress sensitivity. In the past decades great achievements have been made to the simulation models of pressure depletion coalbed methane (CBM) recovery process and CO2 sequestration and...
This work provides a guideline for gecko inspired dry adhesive design and simulation. Mechanical property testing for several polymers commonly used in gecko adhesives (Kraton G1657 thermoplastic elastomer, ST-1060, and ST-1087 polyurethane elastomers) allowed hyperelastic and viscoelastic...
Touch is one of the most important sensory inputs during the performance of surgery. However, the literature on kinesthetic and tactile feedback—both called haptic—in surgical training remain rudimentary. This rudimentary knowledge is partially due to the fact that haptic feedback is difficult to...
