1+ hour, 16+ min ago   (385+ words) This study examines the hovering and forward-flight stability of a heavy-lift coaxial unmanned helicopter with a suspended payload. A six-degree-of-freedom dynamics model is developed, coupling the rotor, fuselage, and a rigid-body sling via a universal joint, while neglecting rotor–payload…...

12+ hour, 20+ min ago   (595+ words) The article is devoted to the current problem of optimizing transport flows implemented within a mechanical engineering enterprise, where the efficiency of logistics operations directly affects the productivity and competitiveness of production. Optimization of the parameters of transport flows implemented…...

21+ hour, 24+ min ago   (538+ words) Last-mile delivery is constrained by manual cargo handling, which consumes a large share of the operating window and limits the number of delivery rounds per shift. This study evaluates the operational and economic effects of the Automated Horizontal Loading and…...

5+ day, 20+ hour ago   (454+ words) This study presents a data-driven Digital Twin framework designed for the non-invasive parameter optimization of closed-loop, factory-installed Adaptive Cruise Control (ACC) systems for eco-driving without modifying electronic control unit (ECU) firmware or requiring external infrastructure. High-frequency telematics data (OBD-II and…...

6+ day, 18+ hour ago   (740+ words) Dynamic heterogeneous vehicle routing with time windows requires reoptimization whenever customer arrivals and network disruptions change the decision space and the set of feasible routes. A reoptimized plan is useful in practice only if it does not rewrite the schedule…...

1+ week, 3+ day ago   (520+ words) Airside vehicles operate close to aircraft, service equipment and safety-critical surface markings, yet driver-assistance functions developed for road traffic do not directly transfer to airport aprons, taxiways and service roads. This article presents a vision-based driver-assistance and warning prototype for…...

1+ week, 5+ day ago   (566+ words) The study addresses the design and development of a unified corporate information system for multimodal transport and logistics companies engaged in maritime and railway transportation. Analysis of the existing literature revealed the absence of a coherent methodological framework for the…...

2+ week, 6+ day ago   (460+ words) The scientific paper is focused on research into the effect of the end tanks’ material on the automotive engine’s radiator and the effect of the air-cooling mode on the efficiency of heat dissipation under engine idling conditions. Aluminium (AL) and…...

3+ week, 1+ day ago   (571+ words) Autonomous parking is one of the most demanding manoeuvres a vehicle can be asked to perform. The available space is small, the margins for error are narrow, and the vehicle must achieve an exact final pose while respecting non-holonomic constraints....

3+ week, 1+ day ago   (375+ words) This study examined how different forms of tourism promotional materials are associated with visual attention and factual recall under natural viewing conditions. A total of 87 participants completed eye-tracking and memory-test tasks using text-only, image-only, and mascot–text composite promotional materials…...
