UAV localization in denial environments is a hot research topic the field of cross-view geo-localization. The previous methods tried to find corresponding position directly satellite image through image, but they lacked consideration spatial information and multi-scale information. Based on method finding points with an we propose novel architecture—a Weight-Adaptive Multi-Feature fusion network for (WAMF-FPI). We treat this positioning as low-level task achieve more accurate by restoring...

This paper presents a novel algorithm for industrial robot trajectory planning based on the NURBS(Non-Uniform Rational B-Spline) curve and Slerp interpolation aiming at problems that of six-axis is not smooth enough in operation process, posture process non-uniform, starts stops frequently. Firstly, first problem, NURBS presented to improve smoothness curve. Combined with quaternion description, which realizes uniform change robot’s end-effector. Secondly, second S-velocity interval robot,...

A new polynomial fitting model based on a neural network is presented to characterize the hysteresis in piezoelectric actuators. As multi-valued mapping, and traditional networks can only solve one-to-one mathematical proposed expand input of by converting into mapping. Experiments were performed under designed excitation with different driven voltage amplitudes obtain parameters using method. The simulation results good accordance measured data demonstrate precision which predict...

This paper presents a fish disease diagnosis system using the short message service (SMS) which can compensate lacking of computer and inconvenient Web-debased for poor basic-establishment in countryside China. study is based on broad mobile phone, convenience technology platform, an equipment send receive message. The input format user process diagnose SMS platform was designed implemented by Java language. has been pilot used proved to be very useful design tool with high accurate rate...

Finite element model of a electromagnet module was established on the dimensions long stator linear synchronous in TR08 Maglev vehicle order to study performance motor. The distribution electromagnetic field levitation air gap analyzed detail, then curve propulsive force and were obtained under different spans. variation trend highlighted along with armature current, excitation position, experiential models derived by Global optimization algorithm conjugate-gradient method. It found that...

Independent Component Analysis (ICA)[2] is a method of finding unknown source signals from signal mixtures, and it just one many solutions to the Blind Source Separation(BSS)problem. This research focuses on "Infomax" algorithm, which finds number independent same mixtures by maximizing entropy signals. For small numbers (two three), Infomax algorithm was found be rather efficient

The mathematical model and the self-organizing optimization algorithm are proposed to solve cast planning problem which determines number as well selection sequence of charges. is modeled traveling salesman with objective minimum sum fixed fees, continuous-cast penalty costs consecutive charges unselected costs. algorithm, inspired by Synergetics, composed competition factor, cooperation operator order parameters. actual example shows effectiveness for problem.

This paper presents a novel algorithm about the industrial robot contouring control based on NURBS (non-uniform rational B-spline) curve. First, aiming at error between robot’s actual trajectory and desired trajectory, contour is proposed as evaluation index, estimation of tangent approximation proposed. Based algorithm, in local task coordinate frame to realize transformation from Cartesian frame. Second, according configuration robot, modified cross-coupling scheme designed. Finally,...

Mating behavior is essential for sexual reproduction, and it often modulated by key chemical cues. In many moth species, males find compatible mates through the reception of sex pheromones which are released females. Pheromone receptors (PRs) elements in sensing these signals. Concurrently, male moths emit a complex blend volatile compounds during courtship; however, mechanisms recognizing putative remain poorly understood. Here, we employed gas chromatography coupled with...

The development of Internet information technology provides more choices for modern teaching methods and modes. method accounting major has changed greatly with the school-enterprise alliance model. This article introduces that under technology, enterprises can provide students a real training environment through distance education, while school flexible labor reserve resources. joint shortens between application this combination industry academia, achieves win-win situation all parties....

For the question of losing data when large amounts fasting calculation while acquisition in raw silk inspection, it is proposed this paper that multithread and circle buffer technique are used to solve question. The size, algorithm defect classing, treatment multi-thread put forward. method proved be feasibility effectively through experiment.

The mathematic model of the hydraulic servo system can be simplified as a series connection valve friction dead zone nonlinear and linear three-order system. is always static. paper proposed method that an inverse which realized on neural networks used for compensting nonlinear. On other hand, parameters part perturbation with influence pressure oil supply, viscosity temperature environment. So fuzzy PI control algorith are solving above problem. result simulation show effectively deal...
