Flow-batch analyzer for the chemiluminescence determination of catecholamines in pharmaceutical preparations
(Taylor & Francis, 2011-01)
A novel, simple, cheap, flexible, versatile, and highly sensitivity flow-batch analyzer (FBA) with chemiluminescence detection was developed for determination of dopamine, norepinephrine, and epinephrine in pharmaceutical ...
A variational shape optimization approach for image segmentation with a Mumford-Shah functional
(Society for Industrial and Applied Mathematics, 2008-12)
We introduce a novel computational method for a Mumford-Shah functional, which decomposes a given image into smooth regions separated by closed curves. Casting this as a shape optimization problem, we develop a gradient ...
Acoustic and vision power aware nodes for Sensor Networks
(Universidade Federal do Rio Grande do Sul. Instituto de Informática, 2006)
An intelligent network of sensors permits to acquire and fuse data in a private zone where the sensors have to be unfolded. This at the same time permits to automate and to plan functions of high level as monitoring and ...
Adaptive finite element method for shape optimization
(Cambridge University Press, 2012-10)
We examine shape optimization problems in the context of inexact sequential quadratic programming. Inexactness is a consequence of using adaptive finite element methods (AFEM) to approximate the state and adjoint equations ...
Tilt scanning interferometry: A numerical simulation benchmark for 3D metrology
(Optical Society of America, 2009-06)
Tilt scanning interferometry (TSI) is a novel experimental technique that allows the measurement of multicomponent displacement fields inside the volume of a sample. In this paper, we present a simulation model that allows ...
B group vitamins: Current uses and perspectives
(IntechOpen, 2018)
This book contains eight chapters dealing with different aspects of B-group vitamins including their roles, uses, and perspectives. Authors from seven different countries (Argentina, India, Japan, Malaysia, Serbia, Turkey ...
DRIFT+MS Quantitative Study of the CO Oxidation on Gold supported on Ceria
(VI San Luis School and Conference on Surfaces, Interfaces and Catalysis, 2019)
The steps of the CO oxidation reaction on a Au/CeO2 catalyst was quantitatively investigated using a novel DRIFT cell/micro-reactor. The design and characterization of this DRIFT cell/micro-reactor, coupled with mass ...
Total Reflection X-ray Fluorescence: a valuable analytic tool for environmental and biological studies
(Vibgyor, 2017-08)
This review collects the research of the recent years on biological or environmental studies in which Total Reflection X-Ray Fluorescence Spectrometry (TXRF) was used as a chemical analytical technique for quantification ...
Followee recommendation based on text analysis of micro-blogging activity
(Pergamon-Elsevier Science Ltd, 2013-08)
Nowadays, more and more users keep up with news through information streams coming from real-time micro-blogging activity offered by services such as Twitter. In these sites, information is shared via a followers/followees ...
On-line micellar-enhanced spectrofluorimetric determination of rhodamine dye in cosmetics
(Elsevier Science, 2008-03)
A simple FI-fluorimetric analytical methodology for the continuous and sequential determination of rhodamine B (RhB) in cosmetic products has been developed and evaluated in terms of sensibility and selectivity. The influence ...
