Fiducial markers play a fundamental role in various fields which precise localization and tracking are paramount. In Augmented Reality, they provide known reference point the physical world so that AR systems can accurately identify, track, overlay virtual objects. This accuracy is essential for creating seamless immersive experience, particularly when prompted to cope with sub-millimeter requirements of medical industrial applications. research article presents comparative analysis four...
Robotic competitions stand as platforms to propel the forefront of robotics research while nurturing STEM education, serving hubs both applied and scientific innovation. In Portugal, Portuguese Robotics Open (FNR) is an event with several robotic competitions, including Robot@Factory 4.0 competition. This competition presents example deploying autonomous robots on a factory shop floor. Although literature has works proposing frameworks for original version competition, none them proposes...
Abstract The ready biodegradability of four chelating agents, N,N′-(S,S)-bis[1-carboxy-2-(imidazol-4-yl)ethyl]ethylenediamine (BCIEE), N′-ethylenedi-L-cysteine (EC), N,N′-bis (4-imidazolymethyl)ethylenediamine (EMI) and 2,6-pyridine dicarboxylic acid (PDA), was tested according to the OECD guideline for testing chemicals. PDA proved be a readily biodegradable substance. However, none other three compounds were degraded during 28 days test. Chemical simulations performed in order understand...
Environmental concerns related to the use of synthetic iron chelates, usually non-biodegradable, for overcoming chlorosis motivates search alternative compounds. Thus, main aim this work was evaluate siderophore, azotochelin, and a siderophore mimic, N-dihydroxy-N,N’-diisopropylhexanediamide (DPH) as potential sources cucumber plants grown in hydroponic cultures. The behavior chelates azotochelin DPH, substrate ferric chelate reductase (FCR) ability suppliers chlorotic studied compared with...
The pose estimation of a mobile robotic system is essential in many autonomous applications. Inertial sensors provide high-frequency measurements that can be used to estimate the displacement, however, for estimating orientation, an additional filter required. Some newest Attitude and Heading Reference Systems referenced orientation device, allowing it retrieve system. However, magnetic field perturbations caused by ferromagnetic objects or induced fields might influence these systems and,...
The binding ability of cadmium(II), lead(II), and zinc(II) with N,N′-(S,S)bis[1-carboxy-2-(imidazol-4yl)ethyl]ethylenediamine (BCIEE) the structure formed complexes have been investigated, in aqueous solution, by potentiometry 1H NMR 13C spectroscopy for first time. Stability constants cadmium, lead, zinc BCIEE were studied glass electrode (GEP) at a fixed total ligand to metal concentration ratios, varied pH values (25.0 ± 0.1) °C, an ionic strength 0.1 M KCl. For Cd-BCIEE Pb-BCIEE systems,...
Solution equilibrium studies on the M(II) [Co(II), Cu(II), and Ni(II)] N,N′-(S,S)-bis[1-carboxy-2-(imidazol-4-yl)ethyl]ethylenediamine (BCIEE) systems have been performed by pH potentiometry UV−visible spectroscopy in 0.1 M KCl at 25 °C. Overall stability constants were established, potentiometry, for all M(II)−BCIEE systems. Results evidenced formation of a highly stable ML complex with systems, which is dominant species over wide range pH, plus different protonated, MHxL, complexes. From...
Current industrial environments have multiple robots working alongside humans, thus providing an operator the ability to perceive robot's workspace correctly and anticipate its intentions movements through visualization of digital twin is utmost importance for safe productive human-robot collaboration scenarios. Much has been studied regarding single human-single robot collaborative scenarios, but few address multi-user multi-robot To this end, paper presents a multi-operator architecture,...
Over 800 remedial wellwork operations are performed each year at Prudhoe Bay. A hierarchy of performance measures and targets has been developed to facilitate the management optimization such a large costly program work. The paper discusses Wellwork Evaluation Tracking System (WETS) which used over past 7 years assess benefits achieved by given operation, taking into account appropriate facility constraints. describes process employed for using ensure timely identification both problems...
