Abstract As the demands in function versatility, integration density and mass manufacturability grow, multilayer thermoplastic microfluidic devices with sophisticated structures have rapidly gained interests. Yet, great challenges persist packaging process, namely alignment sealing of multiple layers, since current schemes are typically labor-intensive lack automation. Herein, we introduce Alignment-free Solvent-enabled Automatic Packaging (ASAP), a novel methodology that combines bonding...
The errors of an inertial navigation system (INS) in response to gyros' can be effectively reduced by the rotation technique, which is a commonly used method improve INS's accuracy. A gyro's error consists deterministic contribution and stochastic contribution. compensation effects are clear now, but as yet unknown. However, always needed rotational system's (RINS) analysis optimization study. In this paper, errors, modelled Gaussian white (GW) noise plus first-order Markov process, analysed...
Noncommutativity error of a strapdown inertial navigation system (SINS) in an unmanned aerial vehicle's (UAV) vibration environment is analysed. The traditional analysis noncommutativity errors based on coning motion model, which inconsistent with UAV's environment. In this paper the form discussed and modelled as sinusoidal angular random vibration. Then, SINS models under these two forms are built up formulas for derived separately. addition, effect multi-sample algorithm explored,...
At present, multiple unmanned aerial vehicles (UAVs) collaboration have attracted people’s more and attention. The abundant relative distance information in UAV cooperative network can be employed to further improve UAV’s positioning accuracy. However, the traditional distance-based localization (CL) algorithm does not consider performance of navigation information. Cooperative with poor will affect follower state estimation Thus, this article proposes a weight factor graph CL method based...
We call a strapdown inertial navigation system (SINS) that uses the rotation auto-compensation technique (which is common method to reduce effect of bias errors components) ‘rotational SINS’. In rotational SINS, rotary table an important component, rotating sensor assembly back and forth in azimuth accomplish error modulation. As consequence manufacturing process, may exist tables which decrease accuracy SINSs. this study, are considered terms installation error, wobble angular models these...
Turntable is an important part of rotation inertial navigation system (RINS). Due to machining accuracy, there exists certain angle error between vertical axis the turntable and table axis, which leads table's vibration further loss RINS's accuracy. Firstly, turntable's modeled. And analysis results show that measurement unit (IMU) does coning because vibration. Then, conning caused by motion analyzed, effect multi-sample compensation algorithm based on equivalent vector discussed. At same...
To solve the problem that dynamic Allan variance (DAVAR) with fixed length of window cannot meet identification accuracy requirement fiber optic gyro (FOG) signal over all time domains, a analysis method time-variant based on fuzzy control is proposed. According to characteristic FOG signal, controller inputs first and second derivatives designed estimate DAVAR. Then variances signals during are simulated obtain DAVAR describe time-varying signal. Additionally, performance evaluation index...
The high-precision positioning of the shearer is key technology to realize automation longwall mining. Since mine a Global Position System (GPS)-denied environment, highly autonomous Inertial Navigation (INS)/odometer integrated navigation has been widely used. At present, method based on INS/odometer difficult meet requirements long-time and Aiming at in complex environment mining, this paper constructs comprehensive rail kinematics model that does not rely external sensors. By analyzing...
Cooperative localization (CL) utilizing multiple unmanned aerial vehicles (UAVs) has become the current development trend and research hotspot. The traditional distance-based CL method typically uses principle of spherical intersection to achieve UAV high-precision positioning. However, this strategy requires several leader UAVs at known positions. Thus, a cooperative for leader–follower using continuous relative ranging information is proposed in paper. Aiming formation consists node with...

This study investigates the effects of domestic market integration (DMI) on corporate export behaviour. Utilizing a regional DMI index and data from Chinese A-share listed multi-product firms between 2006 2015, we find that expands scale reinforces firms' behaviours. Specifically, quality-based competence upgrade quality their core products, whereas cost-based reduce prices products. These findings have significant implications for emerging countries implementing upgraded international trade...
Cerebral microbleeds (CMB) is an important type of cerebral microbleeds. In recent years, many studies have proved that CMB can not only cause vascular dementia, but also increase the risk stroke. Therefore, detection great clinical significance for balancing antithrombotic therapy and assessment in stroke patients, value diagnosis prognosis cranial injury. This paper mainly proposes a two-stage framework based on deep learning, which includes screening stage brain microhemorrhagic candidate...

Performance-based navigation (PBN) operations based on the required performance (RNP) are trend for civil aviation in future. In order to further ensure safety and efficiency of operation, RNP will transition from 2D 3D/4D. Accurately evaluating actual three-dimensional directions (3D ANP) under aircraft operation is important guarantee safe flight aircraft. However, traditional two-dimensional ANP evaluation method mainly focuses plane along track, lacks vertical direction. Moreover,...
