Evaluation of Remotely Sensed and Interpolated Environmental Datasets for Vector-Borne Disease Monitoring Using In Situ Observations over the Amhara Region, Ethiopia

Sensors, 2020
Despite the sparse distribution of meteorological stations and issues with missing data, vector-borne disease studies in Ethiopia have been commonly conducted based on the relationships between these diseases and ground-based in situ measurements of ...

Chirplet approximation of band-limited, real signals made easy

, 2008
In this paper we present algorithms for approximating real band-limited signals by multiple Gaussian Chirps. These algorithms do not rely on matching pursuit ideas.

Coherent control of ultracold 85Rb trap-loss collisions with nonlinearly frequency-chirped light

, 2011
We present results on coherent control of ultracold trap-loss collisions using 40 ns pulses of nonlinearly frequency-chirped light. The chirps, either positive or negative, sweep ~1 GHz in 100 ns and are centered at various detunings below the D2 line of

Observational Limit on Gravitational Waves from Binary Neutron Stars in the Galaxy [PDF]

, 1999
Using optimal matched filtering, we search 25 hours of data from the LIGO 40-meter prototype laser interferometric gravitational-wave detector for gravitational-wave chirps emitted by coalescing binary systems within our Galaxy. This is the first test of

Best network chirplet-chain: Near-optimal coherent detection of unmodeled gravitation wave chirps with a network of detectors

, 2007
The searches of impulsive gravitational waves (GW) in the data of the ground-based interferometers focus essentially on two types of waveforms: short unmodeled bursts and chirps from inspiralling compact binaries.

Hybrid chirped pulse amplification [PDF]

Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2002
We present a novel chirped pulse amplification method which combines optical parametric amplification and laser amplification. High efficiency is achieved without the use of electro-optic modulators using a simple tabletop pump laser.
