In this paper, we propose an efficient continuous-time LiDAR-Inertial-Camera Odometry, utilizing non-uniform B-splines to tightly couple measurements from the LiDAR, IMU, and camera. contrast uniform B-spline-based methods, our B-spline approach offers significant advantages in terms of achieving real-time efficiency high accuracy. This is accomplished by dynamically adaptively placing control ...

Abstract Construction Semantics (CxS) uses FrameNet frames to capture the semantic properties of grammatical constructions. It closes a gap between Frame and usage-based Grammar as well providing uniform format implement into constructicographic work. This article provides an overview three core features CxS. Starting point is (i) modeling associated with constructions in terms types frames. ma...

We study the relation between large-scale structures in concentration field with those velocity a dye-seeded turbulent jet. The scalar plane is measured using laser-induced fluorescence. Uniform zones of an advected are identified cluster analysis. simultaneously measure two-dimensional particle image velocimetry. characterized by finite-time Lyapunov exponents. measurement scalarand fields mov...

We consider lattices generated by finite Abelian groups. The main result says that such a lattice is strongly eutactic, which means the normalized minimal vectors of the lattice form a spherical 2-design, if and only if the group is of odd order or if it is a power of the group of order 2. This result also yields a criterion for the appropriately normalized minimal vectors to constitute a unifo...

In this paper we present methods for parallelization of 3D CFD forest fire modelling code on Non-uniform memory computers in frame of the OpenMP environment. Mathematical model is presented first. Then, some peculiarities of this class of computers are considered, along with properties and limitations of the OpenMP model. Techniques for efficient parallelization are discussed, considering diffe...

We present preliminary results connrming the importance of radiometric calibration in multicamera applications. We review systematic and random noise in the video sensor (camera/frame grabber). The manifestation of background noise in dark images, and xed pattern noise in at elds are illustrated. Through a at-eld correction of an uniform intensity stereo image pair an improvement of 26% to 59% ...

 A VOF-CSF model is developed to model slug flow in capillary channels  Non-uniform mesh is employed to reduce the simulation expenses  A moving reference frame is set moving along or opposite to the gas slug to eliminate the spurious current  The calculated liquid film thickness, slug velocity, and circulation flow ahead the gas slug are all agree very well with literatures Approach and Im...
