The Effect of Shallow Water on Roll Damping and Rolling Period
… effort has been made to quantify and predict roll damping of vessels in the past. Similarly, efforts have been made to provide effective methods for calculating the roll gyradius of vessels. Both the damping and the gyradius of a vessel are traditionally quantified through the use of a sally …

Scenario analyzer for real-time Dynamic Transportation Assignment (DTA) systems
… predictions of the network state within a rolling horizon framework. However, there exist several network control instruments (such as incentive schemes under daily budget constraints) whose optimization necessitate generating predictions beyond the "roll period" and for the entire day. …

Hydrostatic and intact stability analysis for a surface ship
… center of gravity to ensure a sea kindly roll period, stability in beam winds, and stability in high speed turns. Various computational tools can be used to compute the hydrostatic and stability properties of a ship. This thesis explores the results from two computer aided design tools …

Runway Exit Speed Estimation Models
… The five phases are: 1) a flare phase, 2) a free roll period occurring between the aircraft touchdown and the brakes initiation 3) the braking phase, 4) a second free roll phase starting after the braking phase and ending before the turnoff maneuver and 5) a turnoff maneuver phase. The major …

Skin Friction and Cross-flow Separation on an Ellipsoidal Body During Constant Yaw Turns and a Pitch-up Maneuver with Roll Oscillation
… turns and a pitch-up maneuver, each with roll oscillation were studied for the first time. The detailed, low uncertainty, flow topology data provide an extensive experimental database on the flow over non-BOR hull shapes that does not exist anywhere else in the world and serves as a …

Price volatility and liquidity cost in grain futures markets
… its usefulness to forecast price volatility in periods of moderate and heightened uncertainty. Using data from corn, soybeans and wheat futures contracts in 1989-2011, statistical tests and estimation results indicate that much of the long memory patterns arise from seasonality and structural …

Three Essays On Agricultural Futures Traders
… on contract returns or volatility during the roll period. Results show index traders do not have a widespread impact on returns or volatility and in some cases actually decrease volatility bringing stability to the marketplace. The futures markets have adjusted to the presence of the new …
