A force-directed approach for offline GPS trajectory map matching
, 2018 We present a novel algorithm to match GPS trajectories onto maps offline (in batch mode) using techniques borrowed from the field of force-directed graph drawing.

River‐Scale Evaluation of a Floating LED Light Array for Behavioral Guidance of American Eel
River Research and Applications, EarlyView.ABSTRACT Exploiting the sensory physiology of migratory fishes to guide them away from hazards like hydroelectric turbines is of interest to regulatory agencies and hydropower operators to achieve conservation and management goals. Here we describe a river‐scale experiment where out‐migrating adult American eel (Anguilla rostrata) were tracked ...

Determination of ship's plane trajectory curvature by GPS
, 2010 W artykule przedstawiono sposób określania krzywizny trajektorii statku w płaszczyźnie horyzontu z wykorzystaniem ciągu pozycji GPS. Stosując aproksymację średniokwadratową ciągu pomiarów współrzędnych pozycji, możemy otrzymać równania parametryczne ...

T-DBSCAN: A Spatiotemporal Density Clustering for GPS Trajectory Segmentation
, 2014 Trajectory data generated from personal or vehicle use of GPS devices can be utilized for travel analysis and traffic information service, whereas trip segmentation is a key step toward the semantic labelling of the trajectories. Two issues are difficult

Remote Sensing in Ecology and Conservation, EarlyView.We evaluated single‐ and multi‐sensor UAV approaches for classifying tree species and standing dead trees in boreal forests, focusing on key biodiversity indicators such as European aspen. Using spectral and structural features extracted from RGB, multispectral (MSP), and LiDAR point clouds for 1,205 field‐measured trees, we compared classification ...

Preprocessing Procedure for Propagation Measurements on MEO Satellite Links
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper presents a software tool designed for preprocessing data from an experimental campaign aimed at characterizing the tropospheric propagation channel using Medium Earth Orbit (MEO) satellites. The collected data provide critical insights into the channel in scenarios involving continuous variations in azimuth and elevation, along with

Design of Unmanned Underwater Vehicle (UUV) For Precision Targeting Using Simple PID-Controler
, 2009 A model of an Unmanned Underwater Vehicle (UUV) for precision targeting using simple PID controller has been designed. The system has been assumed to have two-dimensional character, such that the mechanical control mechanism would be performed solely by ...

Visual cueing for collision avoidance system [PDF]
, 2012 The modern Traffic Alert and Collision Avoidance System (TCAS) used in airlines today is the TCAS II. It provides pilots with both Traffic Advisory (TA) and Resolution Advisory (RA) which in turn reduces the incidence of mid-air collisions.
