RISA Comparison of Two Techniques for Generating Nowcasting Ensembles. Part I: Lagrangian Ensemble Technique
Publisher: American Meteorological Society
Abstract: agrangian extrapolation of recent radar observations is a widely used deterministic nowcasting technique in operational and research centers. However, this technique does not account for errors due to changes in precipitation ...
A Comparison of Two Techniques for Generating Nowcasting Ensembles. Part II: Analogs Selection and Comparison of Techniques
Publisher: American Meteorological Society
Abstract: owcasting is the short-range forecast obtained from the latest observed state. Currently, heuristic techniques, such as Lagrangian extrapolation, are the most commonly used for rainfall forecasting. However, the Lagrangian ...
Analogs on the Lorenz Attractor and Ensemble Spread
Publisher: American Meteorological Society
Abstract: ntrinsic predictability is defined as the uncertainty in a forecast due to small errors in the initial conditions. In fact, not only the amplitude but also the structure of these initial errors plays a key role in the ...
Simultaneous Cross Section and Launching Nose Optimization of Incrementally Launched Bridges
Publisher: American Society of Civil Engineers
Abstract: The conventional design process of the launching nose of an incrementally launched bridge is usually based on parametric models with great limitations and the use of a trial and error technique to improve the design. Facing ...

Application of CRONE Control to a Sampled Time Varying System With Periodic Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An application of CRONE robust control extended to discrete-time-varying systems with periodic coefficients is presented. The application is carried out in the frequency domain through the ...
Improved Optimization Formulations for Launching Nose of Incrementally Launched Prestressed Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: The conventional design process of a launching nose of an incrementally launched bridge is based on trial-and-error methods to reduce bending moment of prestressed concrete deck at the foremost support during launch. With ...
A Hybrid Stochastically Perturbed Parametrization Scheme in a Convection-Permitting Ensemble
Publisher: American Meteorological Society
Abstract: AbstractModel error in ensemble prediction systems is often represented by either a tendency perturbation approach or a process-based parameter perturbation scheme. In this paper a novel hybrid stochastically perturbed ...
Kinematic Design of a New Four Degree-of-Freedom Parallel Robot for Knee Rehabilitation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rehabilitation robots are increasingly being developed in order to be used by injured people to perform exercise and training. As these exercises do not need wide range movements, some parallel robots with lower mobility ...
Low Reduced Frequency Theory of Airfoils Vibrating in Complex Modes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper extends a previous study on the unsteady aerodynamics of vibrating airfoils in the low reduced frequency regime to the case of complex modes, where the phase of the different points of the same airfoil is not ...
