Insurance distribution remains strategically relevant in mature markets, particularly when customer access and product placement depend on intermediated channels. In Portugal, agents continue to play an important role in Non-Life and protection insurance. For Grupo Ageas Portugal, the channel provid…

Aging Characterization and Simulation Analysis of IGBT Power Devices
— 2026
This paper focuses on device failures easily triggered by bonding wire aging and gate oxide aging during long-term operation of IGBT, and conducts research on these two typical aging modes. Starting from failure mechanisms, this paper analyzes the thermo-mechanical coupling fatigue process of bondi…

As modern enterprises struggle to balance financial growth with ecological depletion, this study examines how non-technological synergies, defined as complementarities between marketing and organizational innovations, are associated with firms’ environmental benefits. Previous research has largely e…

Deep Reinforcement Learning-Based Direct Torque Control of PMSM
— 2026
This thesis investigates finite-control-set torque control for permanent magnet synchronous motors under parameter mismatch and multi-objective constraints. An end-to-end controller based on a deep Q-network is proposed to reduce dependence on accurate motor parameters and manual tuning. The torque …

Homogeneous linear majorants of Oscillatory Functions: A Geometric and Asymptotic Study
Zenodo
— 2026
This working paper presents a systematic geometric and asymptotic investigation into how linear functions bound periodically modulated growth, focusing on the prototype family $f_{a,k}(x) = x(1 + a sin(kx))$. By evaluating the asymptotic ratio $R(a)$ between the area under the minimal homogeneous li…
Master's Thesis
— 2026
To address the flexible vibration and residual vibration problems of large flexible spacecraft during attitude maneuvers, a three-dimensional rigid-flexible coupled spacecraft equipped with piezoelectric actuators is investigated in this study. Based on the generalized coordinate method and modal di…

Active Balancing Strategy for Battery Packs in Swapping Stations Based on the Flyback Topology
— 2026
Battery swapping stations can support peak shaving by charging during low-load periods and reducing grid import during peak periods. However, battery packs returned from different vehicles may have different SOC, capacity, resistance, temperature, and ageing conditions. These differences reduce the …
