Anti-swing control of overhead cranes
… and deceleration of the crane generally induce swinging motion in the suspended payload. A method is presented to find the trajectory for an overhead crane that will ensure the transfer of the payload in the shortest time and with minimum swinging along a specified path. The overhead crane and …

The Aerodynamics of Cricket Ball Swing
The technique of swing bowling is used in the sport of cricket to gain an advantage over the batter, and improve a team’s chance of winning a match. The current best practice for swing bowling is based on anecdotal evidence, with little consensus on the optimal strategies. Bowling technique, the …

Multiple Swing Out-of-Step Relaying
… is the identification of multiple unstable swings after a given disturbance. In other words, an Out-of-Step protection scheme that handles a network that behaves as a multi-machine system is presented.

Modelling and simulation of a pressure swing reactor
A Pressure Swing Reactor is a unit designed to incorporate simultaneous reaction and separation into one unit operation. The concept expands on the well-established method of Pressure Swing Adsorption, with the addition of catalyst to allow reaction to take place. The PSR is operated with a four …

SmartBat : a baseball swing analysis and training product
… any form of feedback on a hitter's baseball swing. Since bat speed is so critical in hitting for power, a low cost device that gives information on bat speed and/or acceleration is needed. By having a visual and auditory response indicating the magnitude of acceleration, a batter can get a …

Pressure Swing Assisted Desorption for Atmospheric Water Collection
… method worth exploring is utilizing pressure swings to release this water vapor, and seeing how a combined method of thermal and depressurized desorption would affect the efficiency of this device. An initial MATLAB model showed that the methods, in order of slowest to fastest, should be (1) …

Size reduction characteristics of an experimental swing hammermill
… size-reduction of a combination of both, whereas swing hammermill grinding is due mainly to impact. Rittingers’ and Kicks’ laws are empirical formulas which do not make an attempt to resolve the forces as applied to grinding into their component parts. Possibly the application of the component …

Pricing of Swing Options: A Monte Carlo Simulation Approach
We study the problem of pricing swing options, a class of multiple early exercise options that are traded in energy market, particularly in the electricity and natural gas markets. These contracts permit the option holder to periodically exercise the right to trade a variable amount of energy with …

Mathematical Models For Swing Options And Subprime Mortgage Derivatives.
… of contract in the commodity market known as swing or take-or-pay options. These contracts are American type options where the holder has multiple exercise rights. The goal is to find the optimal consumption process for the underlying commodity. We present a pricing methodology using the …

Swing-Up and Balancing Control of Underactuated Robotic Systems
… experimentally, a complete controller for swing-up and balancing has been designed and implemented on the Pendubot, a two-link underactuated robot. The parameters of the Pendubot were varied by up to 50% in order to test robustness to parameter errors. The robust control scheme using …

Adaptive swing-up and balancing control of acrobot systems
… past effort has been put into understanding the swing-up control of the acrobot system. This thesis implements an online, adaptive swing-up and balancing controller with no previous knowledge of the system's mass or geometric parameters. A least squares method is used to identify the 5 parameters …

Low-swing signaling for energy efficient on-chip networks
… This thesis makes several contributions to low-swing signaling circuit design for the energy efficient on-chip networks in two separate projects: on-chip networks optimized for one-to-many multicasts and broadcasts, and link designs that allow on-chip networks to approach an ideal …

Understanding and Improving Electrochemical CO2 Capture by Supercapacitive Swing Adsorption
… One specific example is Supercapacitive Swing Adsorption (SSA). This avoids the traditional temperature swing used in amine scrubbing and instead relies on a change in the voltage applied to the supercapacitor to reversibly capture CO2. The most significant advantage of using SSA for …
