In this paper, the cyclic constitutive equations were proposed to describe behavior of loading and unloading. Firstly, a coupled damage variable was derived, which contains two parts, i.e., compaction-induced cracking-induced damage. The derived from nonlinear stress–strain relation initial compaction stage, established based on statistical theory. Secondly, total variable, equation rock under monotonic uniaxial compression conditions, whereafter, application model is extended unloading...
Synchronous grouting in shield tunnel construction plays a critical role enhancing impermeability, ensuring precise alignment of segment rings, and mitigating surface settlement. Despite its importance, limited research has been conducted on the visualization numerical simulations for behind wall. This study addresses this gap by simulating diffusion process during post-grouting using CFDEM software. The simulation results reveal that grout injected from upper opening initially diffuses...
Purpose This paper proposes a novel visual-inertial-ranging odometry (VIRO) algorithm that tightly incorporates bundled ultra-wideband (UWB) sensors into existing visual-inertial (VIO), with the aim to provide fully observable robot state estimation. The VIRO estimator proposed in this is first demonstrate full observability. Design/methodology/approach coupled fusion model of measurements based on extended Kalman filter (EKF), where UWB anchors are integrated cohesive sensor network....
Abstract Changing thermodynamic and compositional conditions of producing fields can cause decreased asphaltene stability initiate aggregation, subsequent precipitation, eventual deposition within flowlines. Usage inhibitors that prevent aggregation tackle the problem right at inception is widely preferred. However, such chemistries were observed to be counter-productive led higher in many cases. Thus, raising question what approach works best for assessing stability: Dispersion or...
In this work, we developed an extended surface complexation model (SCM) that successfully fits all tested ζ-potential data (63 in total) of synthetic calcite and three natural carbonates (Iceland spar, Indiana limestone, "SME" rock from a Middle East field) brines with divalent ions wide range ionic strengths (0.001–0.5 M). To develop model, our previous reported SCM is first optimized by incorporating the strength M) along previously published for parameter refitting. The then applied to...
As integrated circuit fabrication advances rapidly and the market for faster, lighter, smaller, yet less expensive electronic products accelerates, packaging faces its own challenges. In this Perspective, Wong, Luo, Zhang describe recent in flip chip packaging. This technology has many advantages over conventional wire bonding offers possibility of low-cost assembly modern products.
This article focuses on designing a consistent and efficient filter for visual-inertial localization given prebuilt map. First, we propose new Lie group with its algebra based which novel invariant extended Kalman (invariant EKF) is designed. We theoretically prove that, when do not consider the uncertainty of map information, proposed EKF able to naturally preserve correct observability properties system. To introduce Schmidt filter. With filter, information can be taken into consideration...
The nanosilica filled composite is a promising material for the no-flow underfill in flip-chip application. However, as filler size decreases into nano length scale, rheological, mechanical, and thermal mechanical properties of change significantly. filler-filler filler-polymer interactions have profound impact on properties. purpose this paper to achieve an in-depth understanding effect surface treatment therefore design nanocomposite formulation with desirable applications. Mono-dispersed...
We have presented a no-reference quality prediction method for asymmetrically distorted stereoscopic images, which aims to transfer the information from source feature domain its target using label consistent K-singular value decomposition classification framework. To this end, we construct category-deviation database dictionary learning that assigns each image indicate if it is noticeable or unnoticeable by human eyes. Then, incorporating category term into objective function, learn...
With the recent advance of deep learning based object recognition and estimation, it is possible to consider level SLAM where pose each estimated in process. In this letter, on a novel Lie group structure, right invariant extended Kalman filter (RI-EKF) for proposed. The observability analysis shows that proposed algorithm automatically maintains correct unobservable subspace, while standard EKF (Std-EKF) does not. This results better consistency comparing Std-EKF. Finally, simulations real...
In recent years, Visual-Inertial Odometry (VIO) has achieved many significant progresses. However, VIO meth-ods suffer from localization drift over long trajectories. this paper, we propose a First-Estimates Jacobian Visual-Inertial-Ranging (FEJ-VIRO) to reduce the drifts of by incorporating ultra-wideband (UWB) ranging measurements into framework consistently. Consid-ering that initial positions UWB anchors are usually unavailable, long-short window structure initialize anchors' as well...

In recent years, multi-sensor fusion has been paid a great attention and is widely applied to simultaneous localization mapping (SLAM), e.g. Visual-Inertial Odometry (VIO). However, in the most of previous works observation noise sensor assumed be Gaussian with invariant constant mean covariance, which not case actually. this paper, variational Bayesian adaptive algorithm proposed improve performance visual-inertial odometry, where covariance modeled as inverse-Wishart distribution harmonic...
Abstract Nonionic surfactants are increasingly being applied in oil recovery processes due to their stability and low adsorption onto mineral surfaces. However, these lead the production of emulsified that is extremely stable difficult separate by conventional methods. This research characterizes crude mixed with a nonionic surfactant, L24–22, brine solution. When subjected gravity separation, middle oil‐rich bottom water‐rich emulsion generated for various water–oil ratios. Thermal...
GSDME is a newly recognized executor of cellular pyroptosis, and has been recently implicated in tumor growth immunity. However, knowledge about the molecular regulators underlying abundance remains limited. Here, we performed integrative bioinformatics analyses identified that epithelial-mesenchymal transition (EMT) gene signatures exhibited positive correlation with levels across human cancers. A causal role was supported by observation EMT dictated reversible upregulation multiple...
