Sustainable mobility with renewable hydrogen: a framework for refueling station design and optimisation using liquid organic hydrogen carriers (LOHCs)
The optimal scheduling model was developed to minimise the total annualised cost of an HRS considering the hydrogen supply chain and LOHC technology. The use of a least-cost optimisation model for operational scheduling in hydrogen refuelling…

Numerical analysis on the airflow organization of a blowing suction dust collector
Physical model
The airflow organization in this paper refers to the parameters of the dust collector domain which could affect the dust collection efficiency of a sweeper vehicle, including the structure of the dust collector, the shape and the…

Analyzing display photometric features through time-dependent dynamics of accommodative responses and ocular imaging quality
Physiological sensitivity to photometric parameters
Before collecting time series data, the 0 and 45th min values of ∆SR and ∆MTF (denoted as ∆SR(45) and ∆MTF(45)) were measured under different light environments characterized by varying…

FEM based thermal and mechanical analysis of comparative study of TIG and A-TIG welding on P91 steel
Heat input is the major factor for application of thermal cycle on weld plate. The following equation gives the heat input:
$$Q = \frac{V*I}{{v*1000}} {\text{kJ/mm}}$$
(1)
where V = Voltage (V),…

Research and application of rock fracturing pressure prediction method for deep oil reservoirs
Geological characteristics of the oil reservoir
The reservoir in the study area is buried at a depth exceeding 6500 m, characterized by weak karstification, leading to relatively dense reservoir development. The porosity primarily ranges from 0.1…

Transmission line insulator defect detection algorithm based on MAP-YOLOv8
Experimental environment
To validate the performance of our proposed method, we built an experimental platform. The platform uses the Ubuntu 20.04 operating system and employs PyTorch version 1.11.01 as the deep learning framework. We chose YOLOv8…
