In the last decade, unmanned aerial vehicle (UAV) sprayers have been growing rapidly worldwide as a new method for pesticide application, especially in Asian countries. More and more manufacturers service providers are currently aiming at UAV spraying operation fruit trees with higher economic value. We evaluated spray performance of an electric six-rotor sprayer using orchard mode (different application volumes flight patterns) hilly apple small sparse (SS) plain tall-spindle...
This paper systematically investigated the topological design of cellular phononic crystals with a maximized gap size between two adjacent bands. Considering that obtained structures may sustain certain amount static loadings, it is desirable to ensure optimized designs have relatively high stiffness. To tackle this issue, we conducted multiple objective optimization maximize band and bulk or shear modulus simultaneously prescribed volume fraction solid material so resulting can be...
Abstract BACKGROUND The use of unmanned aerial vehicles (UAVs) for the application plant protection products (PPPs) in paddy fields is becoming increasingly prevalent worldwide. Despite its growing usage, UAV spraying rice pest control faces practical challenges, including limited canopy penetration, uneven deposition, and significant spray drift. This study investigated impact two tank‐mix adjuvants, Wonderful Rosin (Adjuvant‐1) Tiandun (Adjuvant‐2), at six volume concentrations, on...
Abstract BACKGROUND The unmanned aerial spraying systems (UASS) have gained widespread use for plant protection in recent years. However, spray drift from UASS is a major concern when controlling weeds over large areas and warrants thorough investigation. This study examined the atomization characteristics of herbicide florpyrauxifen‐benzyl under downwash airflow using test platform. Potential was assessed bench (TB) airborne collectors (ADCs) field low wind speeds (<1 m s −1 ). RESULTS...
All-angle negative refraction (AANR) of phononic crystals and its frequency range are dependent on mechanical properties constituent materials their spatial distribution. So far, it is impossible to achieve the maximum operation AANR theoretically. In this paper, we will present a numerical approach for designing two-dimensional crystal with broadband without index. Through analyzing mechanism AANR, topology optimization problem aiming at established solved by bi-directional evolutionary...
Abstract Background Droplets of plant production products sprayed from unmanned aerial spraying system (UASS) applications are prone to drift, threatening nontarget crops, humans, and environment. There few studies that have investigated bioassay UASS spray even fewer when it comes herbicide application. This work reports a combined field‐scale evaluation drift for rice florpyrauxifen‐benzyl application using six‐rotor motor under acceptable operating conditions. An artificial canopy was...
Unmanned aerial spray systems (UASSs) are a commonly used spraying method for plant protection operations. However, their parameters have complex effects on droplet distribution. The large-scale 3D density distribution measurement is insufficient, especially since the downwash wind easily affected by environment. Therefore, there need to develop technique that can quickly visualize In this study, laser imaging was proposed scan moving droplets in air, and test constructed using traveling...
With the aim of solving problems high labor intensity, low operational efficiency, and poor deposition distribution uniformity in mango canopy associated with traditional plant protection devices, an air-ground co-operation stereoscopic system consisting orchard caterpillar mist sprayer a six-rotor UAV was designed to jointly undertake operations orchards. We tested spraying performance on trees, compared single-machine operation, air–ground could significantly increase droplet coverage...
Dielectric elastomer actuators (DEAs), a type of “artificial muscles”, can generate significant deformations and offer speedy responses when exposed to voltage. Owing their high electromechanical conversion efficiency great flexibility, they have been extensively used in soft robot applications, such as grippers, walking robots, crawling climbing swimming etc. Although previous research has explored the use DEAs locomotion, achieving optimal behavior is challenging due complexity constituent...
Cleft palate is a congenital deformity with soft tissue and hard defects. Normal cleft repairing surgery only repairs defects, whereas bone defects in the still exist. Therefore, we conducted this study beagles to observe influence of grafting at primary on craniofacial growth occlusal relationships individuals complete provide experimental evidence for optimal surgical procedures palate. Using 60 beagle puppies as subjects, tested effects surgically induced palatal defect. The animals were...
The size effects that reveal the dramatic changes of mechanical behaviour at nanoscales have traditionally been analysed for regular beam systems. Here, method using finite-element analysis is explored with intention evaluating complex nanostructures. surface elasticity theory and generalized Young–Laplace equation are integrated into a element to account in classical Euler–Bernoulli Timoshenko theories. Computational results match well theoretical predictions on effect cantilever cubic unit...
