A shifting method for dynamic system Model Order Reduction
Model Order Reduction (MOR) is becoming increasingly important in computational applications. At the same time, the need for more comprehensive models of systems is generating problems with increasing numbers of outputs and inputs. Classical methods, which were developed for Single-Input …

Model of the Air System Transients in a Fuel Cell Vehicle
… transient effects in a fuel cell air delivery system. These methods were applied to model the 20 kW automotive fuel cell system that was used in Animul H2, a fuel cell-battery hybrid sedan developed by a group of engineering students at Virginia Tech. The air delivery system included the air …

Dynamic response and maneuvering strategies of a hybrid autonomous underwater vehicle in hovering
… The Odyssey IV AUV has a novel propulsion system, which includes a pair of azimuthing thrusters for maneuvering in surge and heave. An analytical model was developed to describe the complex nonlinear vehicle dynamics, and experiments were performed to refine this model. The fluid dynamics …

Future power system dynamic frequency response under high penetration levels of wind
… which may cause the inertia less problems in the system. The UK National Grid has developed scenarios where high wind power penetration levels are considered which are likely to change the patterns of UK transmission network operation and dynamic performance. Therefore, it is necessary to develop …

Precision control of continuous microcontact printing
… advantages over displacement control. Analytical dynamic models of the system are developed, iterated, and verified experimentally. Initially, a simple model consisting of two separable single-input, single-output (SISO) systems was developed, but this model was shown to fail to capture relevant …

Development of dynamic computational model for an integrated farming system
The use of fossil fuels on farming systems is now widely recognized as unsustainable because of diminishing supplies and the contribution of these fuels to the increasing carbon dioxide concentration in the environment. Moreover, farming systems with higher nutrient usage efficiency are important …

Development of a novel platform for the optimal design, sizing and energy management of grid-integrated hybrid photovoltaic-hydrogen energy systems.
… to scale-up the investment in renewable energy systems. To enable the increased integration of intermittent renewables such as wind and solar energies, while exploiting their full potential, adequate and sustainable energy storage systems are required. Hydrogen (H2) energy storage systems, given …

An analytical investigation of passive and active suspension systems for articulated freight vehicles
… vibration to the driver and high magnitudes of dynamic tire forces to the pavements. The high levels of ride vibration and tire forces are attributed to the excessive sizes and weights of these vehicles. The driver health and safety risks posed by ride vibrations, and the significant tire …

A Bayesian latent time-series model for switching temporal interaction analysis
… switching pattern and signal states and dynamics are inferred from noisy and possibly missing observations of these signals. We propose reasoning over posterior distribution of these latent variables as a means of combating and characterizing uncertainty. This approach also allows for …
