Fatigue strength assessment of ultra-high-strength steel fillet weld joints using 4R method
(Elsevier, 2019-11-30)
A fatigue analysis on experimentally tested transverse fillet-welded non-load-carrying T- and X-joints made of S960 and S1100 ultra-high-strength steel was carried out in the present study. The test data consisted of welded ...
Adaptive MIMO Pole Placement Control for Commissioning of a Rotor System with Active Magnetic Bearings
(Elsevier, 2019-12-19)
Active magnetic bearing (AMB) supported rotor systems require advanced control strategies to meet the increased performance requirements of more and more demanding applications. To meet the particular requirements for the ...
Analytical Evaluation of High-Efficiency Induction Motor Losses
(IEEE, 2019-08-05)
An analytical motor design-based approach is used to evaluate the major loss components of a premium-efficiency (IE3)four-pole squirrel-cage induction machine. In the analytical approach, the geometry of the machine and ...
Current energy policies and possible transition scenarios adopting renewable energy: A case study for Bangladesh
(Elsevier, 2020-03-26)
This study analyses energy transition pathways for the case of Bangladesh. The LUT Energy System Transition model, a high temporal - spatial resolution linear optimisation tool, is used to model an energy system transition ...
Reconfigurable Intelligent Surface-Aided Grant-Free Access for Uplink URLLC
(IEEE, 2020-05-13)
Reconfigurable intelligent surfaces (RISs) have been recently considered as one of the emerging technologies for future communication systems by leveraging the tuning capabilities of their reflecting elements. In this ...
Carbon Handprint
(Springer, Cham, 2020-05-13)
A carbon handprint is a new approach developed to quantify the positive climate impact of products and services. In contrast to carbon footprint, which refers to negative global warming potential as a consequence of ...
Development of coupled neutronics and fuel performance analysis capabilities between Serpent and TRANSURANUS
(Elsevier, 2019-12-02)
Monte Carlo reactor physics code Serpent is coupled with the fuel performance code TRANSURANUS for steady state analyses including fuel depletion calculations. A two-way coupling is developed, such that the codes exchange ...
Massive MIMO-NOMA Networks With Successive Sub-Array Activation
(IEEE, 2019-12-04)
In this paper, we propose a novel successive sub-array activation (SSAA) diversity scheme for a massive multiple-input multiple-output (MIMO) system in combination with non-orthogonal multiple access (NOMA). Considering a ...
The Role of Transmission Grid and Solar Wind Complementarity in Mitigating the Monsoon Effect in a Fully Sustainable Electricity System for India
(The Institution of Engineering and Technology, 2019-11-21)
Various assessments have shown abundant renewable energy (RE) potential for India, especially solar. For a fully sustainable power system, monsoon presents an obstacle with the resultant decrease in solar resource availability. ...
Mitigating noncirculating bearing currents by a correct stator magnetic circuit and winding design
(IEEE, 2020-04-06)
Different mechanisms by which bearing currents flow inside the electrical machine are well studied. In contrast, investigation and development of different techniques to mitigate these currents remain a field for improvement, ...
