Macroeconomic Uncertainty Indices Based on Nowcast and Forecast Error Distributions

The GoMOOS nowcast/forecast system

A circulation nowcast/forecast system has been developed for the Gulf of Maine as an integral component of the Gulf of Maine Ocean Observing System (GoMOOS). It has been used daily since 2001 to produce short-term forecasts of the circulation and hydrographic properties in the Gulf of Maine. One of the expectations is that the nowcast/forecast system can provide consistent SST to fill in AVHRR ...

Ocean Nowcast/Forecast Systems for Improvement of Naval Undersea Capabilities

The U.S. Navy is a major investor in ocean model development. The pay-off of such an investment is the value-added ocean nowcast/forecast systems on naval operations and warfare effectiveness. The purpose of this paper is to investigate the value added of the Navy’s nowcast/forecast system to naval antisubmarine warfare (ASW) and anti-surface warfare (ASUW). The nowcast/forecast versus observat...

Nowcast/Forecast System For Coastal/Open Ocean Regions

LONG-TERM GOALS To develop and evaluate a nowcast/forecast system for coastal/open ocean regions with the Hybrid Coordinate Ocean Model (HYCOM). OBJECTIVES a) To evaluate the model's performance in reproducing the oceanic circulation, with a special focus on the coastal regions; b) To evaluate the model's forecast skills and usefulness in providing boundary conditions for ultra fine-mesh coasta...

On error distributions in ring-based LWE

Since its introduction in 2010 by Lyubashevsky, Peikert and Regev, the ring learning with errors problem (ring-LWE) has become a popular building block for cryptographic primitives, due to its great versatility and its hardness proof consisting of a (quantum) reduction from ideal lattice problems. But, for a given modulus q and degree n number field K, generating ring-LWE samples can be perceiv...
