57+ min ago   (551+ words) Single-axis solar tracker arrays are commonly installed within the lower atmospheric boundary layer. Their wind loads are governed not only by the module tilt angle, row-to-row sheltering and wind-direction angle but also by the inflow turbulence intensity. To clarify the…...

1+ hour, 47+ min ago   (450+ words) Top-hat-type harmonic drives are widely used in industrial robots and high-end equipment due to their large hollow structure, high load capacity, and high precision. However, unlike cup-type harmonic drives, the transmission error characteristics of top-hat-type structures are influenced by assembly-induced…...

3+ hour, 52+ min ago   (358+ words) Zn2SnO4 is a promising anode for lithium-ion batteries owing to its high theoretical capacity, yet its practical utilization is severely limited by sluggish reaction kinetics, large volume expansion, and unstable electrode/electrolyte interfaces. Here, we introduce a dimensionality-reduction strategy that simultaneously…...

5+ hour, 42+ min ago   (466+ words) Advanced battery management systems (BMS) demand high-precision online prediction of lithium-ion battery state of health (SOH). To address engineering challenges where deep learning and multi-physics models struggle with edge deployment on automotive-grade microcontrollers (MCUs) due to high memory footprints and…...

6+ hour, 3+ min ago   (466+ words) This paper presents a model predictive control (MPC)-based energy management strategy for hybrid power systems combining a proton-exchange membrane fuel cell (PEMFC) with a lithium iron phosphate (LFP) battery storage unit for renewable energy applications. The proposed framework optimizes…...

6+ hour, 37+ min ago   (422+ words) Magnetorheological brakes (MRBs) use field-sensitive magnetorheological fluids (MRFs) to provide fast and controllable braking, but conventional electromagnet (EM)-based designs suffer from high power use, heat generation, and limited torque density, which limit their practical efficiency. These limitations highlight the…...

7+ hour, 23+ min ago   (514+ words) This paper addresses the lateral path tracking problem for autonomous vehicles operating over a wide speed range by proposing a speed-adaptive horizon model predictive control (SAH-MPC) strategy. Unlike conventional fixed-horizon MPC, the proposed approach schedules both the prediction horizon Np…...

1+ day, 41+ min ago   (548+ words) The study introduces the Hybrid Anomaly-Filtered Spatio-Temporal Representation Network (HASTRN) to achieve accurate forecasting of short-term and day-ahead energy demand by utilizing smart-meter, solar PV, and weather-integrated data. Energy demand forecasting in residential buildings has become increasingly difficult due to…...

1+ day, 2+ hour ago   (452+ words) Distributed-drive electric vehicles (DDEVs) improve braking stability through independent four-wheel braking torque control, yet their complex multi-brake systems are prone to braking faults that cause loss of longitudinal and yaw stability. This study investigates DDEV braking performance under normal and…...

2+ day, 5+ hour ago   (280+ words) The growing penetration of centralized and distributed solar photovoltaic (PV) generation has introduced significant operational challenges in power systems, most notably the “duck curve” phenomenon, which is characterized by steep net load ramp-up at dusk. This issue has become increasingly…...
