Weather on Target

The long term goal of this project is to develop tools for the automated analysis and nowcasting of conventional and remotely-sensed meteorological data, primarily for use at regional forecast centers, and aboard ship in remote littoral regions in which the Navy operates. In contrast to predicting weather out to several days (the purpose of numerical weather prediction), the purpose here is to ...

Effect of Antifreeze Admixtures on Cold Weather Concrete

Kashmir is located in a region where winter temperatures are very low. During the winter months, the temperature in Kashmir is often below 0⁰ C. Generally concrete placed in colder regions with the help of insulated forms as well as heaters to protect freshly mixed concrete against freezing. These practices try to incorporate unnecessary carbon and leads to an disagreeable carbon footprint. The...

On Modular Signs

We consider some questions related to the signs of Hecke eigenvalues or Fourier coefficients of classical modular forms. One problem is to determine to what extent those signs, for suitable sets of primes, determine uniquely the modular form, and we give both individual and statistical results. The second problem, which has been considered by a number of authors, is to determine the size, in te...
