Accurate calibration of low-cost sensors is critical for improving their potential in environmental monitoring. State-of-the-art (SOTA) methods based on supervised learning commonly calibrate sensor measurements with ground truth from the immediate past or future. However, these techniques rely heavily labeled data which challenging to obtain real-world scenarios. Thus, this paper introduces CaliFormer, a novel representation model using self-supervised extract time- and spatial-invariant...
The landing process of the quadrotors can be affected by disturbance from ground effect when approaching surface. Such a significantly increases chances collision and jittering quadrotors, thereby posing threats to safety both mounted equipment. In light this, we propose SmoothLander, an aerodynamics reinforcement learning-based control system stabilize under influence noise. First, design trajectory for quadrotor in accordance with aerodynamics. Then command generator effectively optimize...
Straw return is a common cultivation to improve soil fertility and realize sustainable agricultural development. However, the effect of returning interval on corn straw humification process in northeast China little known. In this study, four-year field trial was conducted investigate characteristics carbon sequestration under annual deep (T1), biennial (T2), non-straw (T3) Jilin Province, China. order precisely evaluate organic density (SOCD), each horizon divided differently according...
Although modern localization methods have achieved remarkable accuracy with various sensors, there are still some circumstances where only proprioceptive sensing works (Inertial Navigation). However, and navigation using IMU sensors (costing less than $1000) face significant challenges such as low large cumulative errors when traditional filter methods. Furthermore, AI-based approaches, while promising, often yield unpredictable unreliable outputs. This paper proposes FormerReckoning, an...
Drone-based rapid and accurate environmental edge detection is highly advantageous for tasks such as disaster relief autonomous navigation. Current methods, using radar or cameras, raise deployment costs burden lightweight drones with high computational demands. In this paper, we propose AirTouch, a system that transforms the ground effect from stability "foe" in traditional flight control views, into "friend" efficient detection. Our key insight analyzing drone sensor readings commands...
Event cameras excel in high-speed and high-dynamic-range scenarios but are highly sensitive to rain, which introduces significant noise while also revealing detailed rain features. This paper a novel Event-based Rain-Background Decomposition Network that integrates Spiking Neural Networks (SNNs) Convolutional (CNNs). By "Distilling Rain," we reconstruct rain-free background for downstream tasks, by "Collecting extract the physical characteristics of rain. Experimental evaluations demonstrate...
Abstract Fluorine pollution in saline-sodic soils has become an important environmental problem, but little is known about the interaction between Al 2 (SO 4 ) 3 and fluorine when used to improve soils. In this study, batch adsorption experiments were conducted investigate impacts of different with on adsorption, mechanisms characterized by SEM, BET, FTIR, XPS analysis. The results showed that decreased increasing soil salinity, addition increased Among three soils, contributed greatly...
As a typical 5G service, VR service quality has become the focus of attention network operators. Both and Gigabit home broadband have characteristics high bandwidth low latency, could theoretically provide good support to video playback, especially 360-degree panoramic videos. In current study, we explored playback users' viewing feelings under in environment. Our findings indicated that was significantly lower than network. addition, found users were more sensitive stalling frequency during...
