Single sub-micron structures testing platform for chemiresistive gas sensors: Microfabrication process design and assembly by lift method
Devices built at the micro and nanoscales, with high-throughput capability utilizing microfabrication methods, are traditionally achieved by photolithography. In the past decade Metal oxide Semiconductors (MOS) research ...
Inventory of Agaricomycetidae and Phallomycetidae under different conservation strategies by the United States Fish and Wildlife Service at Cabo Rojo, Puerto Rico Refuge
Gasteromycetes, commonly known as puffballs, are an informal group of Basidiomycetes with a polyphyletic origin and since 2014 included in the sub-classes Agaricomycetidae and Phallomycetidae. These fungi are characterized ...
Constructing a confidence region for the optimum values of factors in multiple response problems
This thesis focuses on the construction of a confidence region for localization of the set of optimal values of factors in multiple responses problems, using as objective the loss function proposed by Young-Hyun, ...
Parámetros sísmicos de registros de temblores medidos en Puerto Rico y su distribución geográfica
In the present study the geographical distribution of several seismic parameters calculated for three earthquakes recorded by the Puerto Rico Strong Motion Program (PRSMP) were analyzed. These seismic parameters have ...

Coral reef community structure in La Parguera Natural Reserve ten years after the 2005-06 mass mortalities
La Parguera Natural Reserve has one of the best-developed coral reef ecosystems in Puerto Rico, sustaining an important socio-ecological system. In 2005, an unprecedented high thermal anomaly produced intensive and ...
Detection and discrimination of high explosives on human hair by Raman scattering
High explosives (HE) represent a high risk to the safety and health of the general population. Therefore, there is an ongoing demand for methods of analysis with limits of detection at trace levels for these hazardous ...
Design of a leaky-wave antenna for 5G purposes using gap-waveguide technology
A quasi-uniform leaky-wave antenna for 5G was designed at 39 GHz using the new holey EBG gap-waveguide structure. The antenna is designed for n260 band, with the requirements that it is compact, low-cost and has high-power ...
