A new class of fractional-order variational optical flow models, which generalizes the differential from integer order to fractional order, is proposed for motion estimation in this paper. The corresponding Euler-Lagrange equations are derived by solving a typical problem, and numerical implementation based on Grünwald-Letnikov derivative definition solve these complicated partial equations. Theoretical analysis reveals that model generalization Horn Schunck (first-order) second-order model,...
The presence and the nature of long-range dependent (LRD) are usually characterised by Hurst parameter. In order to meet requirements analysing LRD processes, a number practical estimation methods have been proposed in literature. Furthermore, some efforts made evaluate accuracy validity estimators for processes. practice, however, many signals measured corrupted with various types noises, sometimes even concerned signal itself has infinite variance. such cases, which estimator best...
Query autocompletion is an important and practical technique when users want to search for desirable information. As mobile devices become more popular, one of the main applications location-aware service, such as Web mapping. In this paper, we propose a new solution query autocompletion. We devise trie-based index structure integrate spatial information into trie nodes. Our method able answer both range top-k queries. addition, discuss extension our support error tolerant feature in case...
Deep Brain Stimulator (DBS) is a long-term active implantable medical device. It imperative to study the effects of implantation site and operational environment on its reliability ensure patient safety. This addresses typical environmental stresses affecting DBS leads proposes reliable testing framework for assessing these electrode leads. Furthermore, this work offers practical foundation optimal design quality enhancement wires, providing guidance relevant regulatory evaluation activities...
In manoeuvring target tracking, a primary tradeoff is the robust tracking of manoeuvres against accurate constant velocity (CV) motion. To achieve this goal, an interacting multiple model (IMM) algorithm fusing input estimation (IE) and best linear unbiased (BLUE) filter presented. First, assumption IE modified to track possible manoeuvre fluctuation. Then, innovation sequence modification technique proposed so can be detected estimated sequentially. With improvements above, estimator (MIE)...
Under the influence of high density operation and natural environment, rail surface will appear abrasion damage, which affect safety comfort train. Rail defect detection is an important part to ensure safe efficient railway system. In order distinguish whether there are defects on surface, a method image segmentation based FPSO 2D-Otsu algorithm proposed. The denoised enhanced by adaptive fractional calculus, then segmented algorithm. verify accuracy algorithm, proposed compared with PSO...
Multi-system interaction is an important and difficult problem in physics. Motivated by the experimental result of electronic circuit element "Fractor", we introduce concept dynamic-order fractional dynamic system, which differential-order a system determined output signal another system. The new offers comprehensive explanation physical mechanism multi-system interaction. properties potential applications systems are further explored with analysis anomalous relaxation diffusion processes.
In this article, a method for active implantable medical devices (AIMD) model development is presented. Based on the transmission line model, AIMD can be developed semianalytically using few direct measurements inside American Society Testing and Materials (ASTM) phantom. Folded orthogonal pathways based Hadamard matrix are used to make problem of well-conditioned. Both induced voltage heating models example AIMDs were demonstrate effectiveness method.
In this paper, we derive the impulse response of fractional distributed order low-pass filters. Based on derived analytical response, a method how to perform discretization above filters is presented. Time and frequency domains illustrations are provided.
The joint presence of heavy-tailed distribution and long memory in time series always leads to certain trouble correctly obtaining the statistical characteristics for modeling. These two properties i.e., memory, cannot be neglected analysis, because tail thickness property are critical characterizing essence resulting natural or man-made phenomenon series. Meanwhile, fluctuation varying local parameter may used capture internal changes which underlie externally observed phenomenon....
