Trajectory tracking of underactuated surface vessels: a linear algebra approach
(Institute of Electrical and Electronics Engineers, 2013-07)
This brief presents the design of a controller that allows an underactuated vessel to track a reference trajectory in the x−y plane. A trajectory tracking controller designed originally for robotic systems is applied for ...
Experimental Method to Evaluate the Optical Properties of Aqueous Titanium Dioxide Suspensions
(American Chemical Society, 2005-12)
The evaluation of the radiation field inside a slurry reactor constitutes a central step in the study of photocatalytic reactions. This task can be achieved by solving the radiative transfer equation (RTE) for the system ...
Active control of a backward facing step flow with plasma actuators
(American Society of Mechanical Engineers, 2014-12)
Active control over a backward facing step flow is studied experimentally by means of plasma based devices. The Reynolds number based on the step height h is 1520. An electrohydrodynamic actuator (EHD), dielectric barrier ...
DNA extraction and a cost-effective detection method for Echinococcus granulosus protoscoleces
(Elsevier, 2013-12-06)
Most methods of DNA purification from protoscoleces of Echinococcus granulosus involve the use of expensive kits and may also require a second step after extraction for an effective purification. The present work describes ...
Cobalt phthalocyanine-based submicrometric field-effect transistors
(Wiley VCH Verlag, 2015-03)
We present performance characteristics of nanoscaled cobalt phthalocyanine (CoPc)-based organic field-effect transistors (OFETs) as a function of channel length. We found a channel length range which maximizes the field ...
A tool to prioritize code smells in distributed development
(Institute of Electrical and Electronics Engineers, 2017-10)
A code smell is a symptom in the source code that helps to identify a design problem. Several tools for detecting and ranking code smells according to their criticality to the system have been developed. However, existing ...
Trivalent chromium ion removal from aqueous solutions using low-cost zeolitic materials obtained from exhausted FCC catalysts
(Sage Publications, 2011-07)
The hydrothermal treatment of exhausted FCC catalysts with zeolite was optimized by varying the chemical composition of the synthesis mixture. The zeolitic products obtained were used to evaluate their ability for the ...
Autoridad religiosa y autoridad política en "De haruspicum responso" de Cicerón
(Morcelliana, 2017-12)
The aim of this paper is to analyze the relationship between religious knowledge and belonging to the group of the boni cives, as formulated by cicero in his speech "De haruspicum responso". From our viewpoint, both when ...
Evaluation of impedance spectroscopy as a transduction method for bacterial biosensors
(Institute of Electrical and Electronics Engineers, 2013-02)
Biosensors are simple, feasible and cost-effective devices where biological specificity and selectivity, and electronic miniaturization are combined. Degrading microorganisms, such as the M7 species of Streptomyces genus, ...
The imprint of crop choice on global nutrient needs
(Iop Publishing, 2014-08)
Solutions to meet growing food requirements in a world of limited suitable land and degrading environment focus mainly on increasing crop yields, particularly in poorly performing regions, and reducing animal product ...
