Background:Increasing threat to Central Europe’s forests from the growing population of the European spruce bark beetle Ips typographus (L.) calls for developing highly effective methods of detection of the infestation spots. The main goal of this study was to establish an automatic workflow for detection of dead trees and trees in poor condition of Picea abies using Middle Wave Infrared spectral range obtained from the ***:The studies were conducted in Wigry National Park (Poland) in 2020. A fusion of aircraft thermal data and laser scanning was used. Synchronous with thermal data acquisition ground reference data were obtained for P. abies in different health conditions. Determination of the range of canopy temperatures characteristic of the three condition states (‘healthy’,‘poor condition’,‘dead’) was performed using K-mean clustering. The accuracy of the method was evaluated on two validation sets:(1) individual tree canopies determined by photointerpretation, and (2) automatic segmentation of laser scanning ***:The results showed that the average temperature of ‘healthy’trees was 27.70℃, trees in ‘poor condition’28.57℃, and ‘dead’trees 30.17℃. High temperature differences between ‘healthy’and ‘dead’P. abies made it possible to distinguish these two condition classes with high accuracy. Lower accuracies were obtained for the class of ‘poor condition’, which was found to be confusing with both ‘healthy’and ‘dead’trees. According to results from the first validation set, a high overall accuracy of 0.60 was obtained. For the second validation set, the overall accuracy was reduced by 11%.Conclusions:This study indicates that canopy temperature recorded from the airborne level is a variable that differentiates ‘healthy’spruces from those in ‘poor condition’and the ‘dead’trees. The results confirmed that thermal and airborne laser scanning data fusion allows for creating a quick and simple workflow, which can successfully separate individual tre

Multimodal Integration Processes in Plan-Based Service Robot Control

引用

Tsinghua Science and Technology 2011年第1期16卷 1-6页

作者： dominik Off TAMS Department of InformaticsUniversity of Hamburg

Cross-modal integration processes are essential for service robots to reliably perceive relevant parts of the partially known unstructured environment, We demonstrate how multimodal integration on different abstraction levels leads to reasonable behavior that would be difficult to achieve with unimodal approaches. Sensing and acting modalities are composed to multimodal robot skills via a fuzzy multisensor fusion approach. Single modalities constitute basic robot skills that can dynamically be composed to appropriate behavior by symbolic planning. Furthermore, multimodal integration is exploited to answer relevant queries about the partially known environment. All these approaches are successfully implemented and tested on our mobile service robot platform TASER,

We present a high-order discontinuous Galerkin(DG)scheme to solve the system of helically symmetric Navier-Stokes equations which are discussed in[28].In particular,we discretize the helically reduced Navier-Stokes equations emerging from a reduction of the independent variables such that the remaining variables are:t,r,ξwithξ=az+bϕ,where r,ϕ,z are common cylindrical coordinates and t the *** this,all three velocity components are kept non-zero.A new non-singular coordinateηis introduced which ensures that a mapping of helical solutions into the three-dimensional space is well *** that,periodicity conditions for the helical frame aswell as uniqueness conditions at the centerline axis r=0 are *** the sector near the axis of the computational domain a change of the polynomial basis is implemented such that all physical quantities are uniquely defined at the *** the temporal integration,we present a semi-explicit scheme of third order where the full spatial operator is splitted into a Stokes operator which is discretized implicitly and an operator for the nonlinear terms which is treated *** are conducted for a cylindrical shell,excluding the centerline axis,and for the full cylindrical domain,where the centerline is *** all cases we obtain the convergence rates of order O(hk+1)that are expected from DG *** addition to the first DG discretization of the system of helically invariant Navier-Stokes equations,the treatment of the central axis,the resulting reduction of the DG space,and the simultaneous use of a semi-explicit time stepper are of particular novelty.

Predicting Future Rumours

引用

Chinese Journal of Electronics 2018年第3期27卷 514-520页

作者： QIN Yumeng dominik Wurzer TANG Cunchen School of Computer Science (International School of Software) Wuhan University School of Information Management Wuhan University

Recent uproar of fake news and misinformation on social media platforms has sparked the interest in the scientific community to automatically detect and refute them. The most popular research task to counteract misinformation, Rumour detection, requires repeated signals to reach adequate detection accurate. Consequently,rumour detection recognizes rumours only when they have started spreading and causing harm. We introduce a new task called "rumour prediction" that assesses the possibility of a document arriving from a social media stream becoming a rumour in the future. Note that rumour prediction differentiates itself from rumour detection through instant decision making. This allows refuting misinformation before it spreads and causes harm. Our approach to rumour prediction harnesses content based features in combination with novelty based features and pseudo *** experiments show that we are able to accurately predict, whether a document will become a rumour in the future. Additionally, we show how rumour prediction can significantly improve the accuracy of state-of-the-art Rumour detection systems.
