Autonomous undersea vehicle(AUV) often encounter the problem of track overshoot when moving underwater. To address this issue, this paper proposed a cooperative control strategy that integrated the adaptive line-of-sight guidance algorithm and the three-level hierarchical speed control architecture....

Back groundHelium is an important strategic scarce resource. Presently, helium used in industry originates primarily from natural gas. In contrast, helium in coal measures, generally emerging as coalbed methane (CBM) with a high helium content, serves as a vital supplement to conventional helium res...

Timely detection of early pavement distress is crucial for effective pavement maintenance. A promising approach involves the segmenting the road surface cracks area from its images. However, the previously employed full-resolution residual network (FRRN), when employing a large number of full-resolu...

From a space-time perspective, this paper constructs a CA-SHIRS model to study the psychosocial resonance diffusion of food safety risk, using complex network and cellular automata theory. The CA-SHIRS model is a framework that combines cellular automata with SHIRS (Susceptible–Hidden–Infected–Recov...

The clever eye (CE) algorithm has been introduced for target detection in remote sensing image processing. It originally proposes the concept of data origin and can achieve the lowest average output energy compared to both the classical constrained energy minimization (CEM) and matched filter (MF) m...

This study introduces a flywheel rotor support structure for an active magnetic suspension flywheel energy storage system. In this structure, there is an axial offset between the axial-bearing position and the mass-center of the flywheel rotor, which affects the tilting rotation of the flywheel roto...

Fatigue damage is a primary mode of failure in asphalt pavements under repeated traffic loading. The incorporation of recycled concrete aggregate (RCA) in asphalt mixtures addresses issues of construction waste landfilling while enhancing sustainability. This study investigated the influence of RCA...

Chinese students usually face risks from various aspects in the process of studying abroad. The use of the analytic hierarchy process alone ignores the interplay between the influencing factors and lacks systematic thinking about the identification of key influencing factors due to the intricacies o...

Herein, A new differential magnetic-field probe with parasitic elements is presented. The proposed probe has two pairs of shorted differential loops as parasitic elements, which could enhance the detection sensitivity owing to the increased detection area. The proposed probe comprises a U-shaped loo...

Seismic imaging in areas with complex geological structures, such as steeply dipping strata and lateral velocity variations, remains a significant challenge in geophysical exploration. In this paper, a Kirchhoff pre-stack depth and pre-stack time migration imaging method under the constraint of an i...

While static conscientiousness is known to predict academic success, personality can be particularly dynamic during adolescence. This study adopted a unique change-oriented perspective to examine the longitudinal relationship between within-person changes in conscientiousness and changes in academic...

This paper presents our research on an E-band Radio Frequency (RF) front-end packaging structure based on back-to-back gap waveguide (GW). This design effectively mitigates the impact of air gaps on performance and offers the advantage of large assembly tolerances. Additionally, its back-to-back str...
