Towards Human-Scale Competitiveness: Priority Challenges for Triple Helix towards 2030
(MDPI, 2022)
The future of regions must be built on human-scale competitiveness based on quality employment, sustainability (climate, digital, and demographic), knowledge and skills, new business projects focused on people, and equality ...
Sorption isotherm, glass transition, and diffusion coefficient of polyacrylamide/water solutions
(ACS Publications, 2012)
The sorption isotherm, the glass transition, and the mutual diffusion coefficient of polyacrylamide/water solutions are obtained experimentally. All of these parameters are measured in the concentrated regime by gravimetric ...
Determination of molecular diffusion coefficient in n-Alkane binary mixtures: empirical correlations
(ACS Publishing, 2012)
In this work we have measured the molecular diffusion coefficient of the n-alkane binary series nCi-nC6, nCi-nC10, and nCi-nC12 at 298 K and 1 atm and a mass fraction of 0.5 by using the so-called sliding symmetric tubes ...
The district energy-efficient retrofitting of Torrelago (Laguna de Duero - Spain)
(IOP Publishing, 2019)
The urban growth is estimated to reach up the 66 % by 2050 and consequently the need of resources within the cities will increase significantly. This, combined with the 40 % of energy consumption and 36 % of CO2 emissions ...
Tool Damage and Adhesion Effects in Turning and Drilling of Hardened Steels
(World Academy of Science, 2016)
Noteworthy results have been obtained in the turning and drilling of hardened high-strength steels using tungsten carbide based cutting tools. In a finish turning process, it was seen that surface roughness and tool flank ...
Higher harmonics compensation in grid-connected PWM converters for renewable energy interface and active filtering
(Przegląd Elektrotechniczny, 2011)
The paper presents overview of high-order harmonics compensation methods applied for control of grid-connected converter. Two harmonic compensation methods are presented. One based on band-pass filers cooperating with ...
Visual Odometry in Challenging Environments: An Urban Underground Railway Scenario Case
(IEEE, 2022)
Localization is one of the most critical tasks for an autonomous vehicle, as position information is required to understand its surroundings and move accordingly. Visual Odometry (VO) has shown promising results in the ...
Goal-Conditioned Reinforcement Learning within a Human-Robot Disassembly Environment
(MDPI, 2022)
The introduction of collaborative robots in industrial environments reinforces the need to provide these robots with better cognition to accomplish their tasks while fostering worker safety without entering into safety ...
Impedance-Based Stability Evaluation of Virtual Synchronous Machine Implementations in Converter Controllers
(IEEE, 2018)
This paper presents a stability evaluation of two Virtual Synchronous Machine (VSM) implementations in the control of Voltage Source Converters (VSCs): a current-controlled (CCVSM) and a voltage-controlled (VCVSM) version ...
System Level Optimization of 5 MW Wind Converter using 3L-NPC Topology in Medium Voltage with 1 . 7 kV IGBT
(IEEE, 2020)
Market competitiveness is the main driver in the massive adoption of wind energy, and the optimization of the power converter is crucial for this purpose. Because it has higher efficiency than the two level Voltage Source ...
