We have developed a portable multiexcitation dye laser system pumped by a 308 nm excimer laser, which can collect fluorescence spectra at 11 excitation wavelengths and a white light reflectance spectrum in less than 200 ms. The system is designed to be used in a hospital setting for in vivo tissue analysis based on fluorescence and reflectance spectroscopy. A specially designed optical fiber pr...

The use of Field Programmable Gate Arrays (FPGAs) in accelerators is widespread due to their flexibility, performance, and affordability. Whether they are used for fast feedback systems, data acquisition, fast communications using custom protocols, or any other application, there is a need for the end-user and the global control software to access FPGA features using a commodity computer. The c...

Biodiversity information is essential for supporting environmental studies leading to conservation and sustainable development. It presents a high degree of complexity which includes: spatiotemporal parameters, undefined structure, multidimensionality, a not well-known or agreed vocabulary, large volume and dynamic evolution. To produce results of positive impact for biodiversity, automatic too...

for more than a decade, academic libraries have been wrestling with the thorny issue of managing the acquisition of electronic resources. where are we in the continuum from paper lists to vendor-designed management systems? this paper takes a look at several in-house initiatives around the country, commenting on the successes and failures of the homegrown programs built to track. update and man...

The tensile test is reliable for revealing the fundamental stress-strain relationship. However, researchers have challenges when applying sufficient equipment to comprehend and assess characteristics of low-to-medium-strength materials. This study describes design construction a portable universal testing machine (UTM) investigating mechanical medium-strength components this include two stepper...
