Adaptable Flight Line Planning for Airborne Photogrammetry Using DEM

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Flight line planning is the first step in an aerial photography campaign. Its two key parameters, ground sampling distance (GSD), and overlap should be designed carefully as they will impact subsequent flying workload and even the final mapping accuracy.

Optical Line Recognition Sensors for Line Follower [PDF]

Acta Mechanica Slovaca, 2013
Paper deals with optical line recognition sensors, which are useful for line follower robots. Line follower is the category of robotic contests. The basic idea is to locomote with robot and follows the black line on white surface. Robot design is very frequently based on two wheeled differentially driven undercarriage with third supporting support ...

Perioperative Red Cell Line Trend following Robot-Assisted Radical Prostatectomy for Prostate Cancer

Medicina, 2022
Background and Objective: Blood loss represents a long-standing concern of radical prostatectomy (RP). This study aimed to assess how red line cell values changed following robot-assisted radical prostatectomy (RARP) for prostate cancer (PCa).

Shape of the 4.438 MeV gamma-ray line of ^12C from proton and alpha-particle induced reactions on ^12C and ^16O

, 2001
We calculated in detail the angular distribution of gamma-rays and the resulting shape of the gamma-ray line produced by the nuclear deexcitation of the 4.439 MeV state of ^12C following proton and alpha-particle interactions with ^12C and ^16O in the ...

A Classic and Fuzzy Parallel Hybrid Controller of PD-PI Type for a Two-Wheeled Self-Balancing Robot

Automation
Two-wheeled self-balancing robots (TWSBRs) are difficult to control because they are nonlinear, unstable, and underactuated, particularly when balance, velocity regulation, and line tracking must be achieved simultaneously.

Vortex spectrum in superfluid turbulence: interpretation of a recent experiment

, 2007
We discuss a recent experiment in which the spectrum of the vortex line density fluctuations has been measured in superfluid turbulence. The observed frequency dependence of the spectrum, $f^{-5/3}$, disagrees with classical vorticity spectra if ...
