Practical implementation of secondary control principles in an electro-hydraulic speed-variable drive applied to an injection moulding machine
(American Society of Mechanical Engineers, 2023)
In this work, a hydraulic state of the art injection molding machine is retrofitted with a dual pump drive. The dual pump drive is an electro-hydraulic speed-variable drive, with focus on high bandwidth control through ...
Control of hydraulic injection moulding machine with electro-hydraulic variable-speed drive
(American Society of Mechanical Engineers, 2023)
In this work an industrial hydraulic injection moulding machine, is retrofitted with a electro-hydraulic variable-speed drive. The focus is placed on the injection cylinder, where the design of the hydraulic system is ...
Closing the gap to sufficiency-based absolute climate targets for wood buildings
(Institute of Physics, 2023)
This research investigated the distribution of the global climate planetary boundary (PB) on a national scale. Then it was distributed to a sector-specific carrying capacity by the principles of acquired rights (grandfathering) ...
Readjusting the climate change hyperfocus: how expanding the scope of impact categories will affect the evaluation of wood buildings
(Institute of Physics, 2023)
The sole focus on reducing the climate impact of dwellings by using wood is neglecting other impacts on nature. Therefore, this study clarifies the potential burden shift by considering ten more impact categories than ...
Development of a composite model for predicting urban surface temperature distribution in the context of GIS
(Institute of Physics, 2023)
In this paper, we present a new model for simulating radiation heat transfer and surface temperatures in urban environments, which is a prerequisite for simulating outdoor mean radiant temperature for pedestrians. We propose ...
A Compact Microwave Quadrature Hybrid Coupler Using Capacitive Composite Lines and Meandered Stubs
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-12)
In this paper, a new structure of the quadrature hybrid coupler (QHC) with compact size is proposed using capacitive composite lines and meandered open stubs. The proposed coupler works at 1.6 GHz with a 0.4 GHz bandwidth, ...
Multi-Objective Assessment and Optimization of a High-Temperature Proton Exchange Membrane Fuel Cell: Steady-State Analysis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-12)
The design and operational conditions of high-temperature proton exchange membrane fuel cells (HT-PEMFCs) substantially impact their performance. This model aims to investigate the influence of various parameters on the ...
A Meta-Heuristic Sustainable Intelligent Internet of Things Framework for Bearing Fault Diagnosis of Electric Motor under Variable Load Conditions
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-12)
The study introduces an Intelligent Diagnosis Framework (IDF) optimized using the Grasshopper Optimization Algorithm (GOA), an advanced swarm intelligence method, to enhance the precision of bearing defect diagnosis in ...
