In this paper, we present a cooperative passers-by tracking system between fixed view wall mounted cameras and a mobile robot. The proposed system fuses visual detections from wall mounted cameras and detections from a mobile robot–in a centralized manner–employing a “tracking-by-detection” approach within a Particle Filtering strategy. This tracking information is then used to endow the robot ...

In this paper, we present a cooperative perception system between wall mounted cameras and sensors on-board a mobile robot to : (i) track and follow a given target person wearing a Radio Frequency Identification (RFID) tag, and (ii) facilitate navigation in the presence of passers-by during the execution of this mission. We employ a "trackingby-detection" approach within a Particle Filtering st...

A large eddy simulation (LES) is used to explore the effects of high frequency actuation on a wall-mounted hump geometry. Low frequency forcing at F ∼ O(1) has been shown to increase entrainment through regular shedding of large-scale structures. Using a LES technique previously validated on the baseline and controlled flow over the wall-mounted hump geometry, the effectiveness of high frequenc...

The accuracy of object reconstruction was tested for six high quality digital cameras. Nikon D80, D200, D2X and D3 with the same 24 mm Nikon lens, a Canon EOS 5D with a normal as well as a stabilized 35 mm Canon lens and an Alpa 12 WA with special fixation of a digital camera back and lens were evaluated. All cameras were investigated on a test cube that was designed according to VDI/VDE 2634, ...

The objective of our study was to optimize magnetic resonance image (MRI) sequences and parameters using operative assisted images (three-dimensional images) for radical prostatectomy at 3 tesla (T) MRI. Five healthy volunteers underwent MRI on the 3.0 T scanner. Various sequences and parameters [Cube (TE/TR = 18, 50, 90 ms/2000 ms), FIESTA (TE/TR/FA = 2.4 ms/5 ms/40 degrees, 90 degrees), fSPGR...

Abstract One known method to reduce vortex shedding from the tip of a blade is use end plates or winglets. Although aerodynamic impact such has been investigated in past, no studies exist on effect far-field noise. The aeroacoustic noise reduction three different end-plate geometries experimentally investigated. are applied free wall-mounted symmetric NACA 0012 airfoil and cambered 4412 with an...

In the present paper, we evaluate performances of three stochastic models for particle dispersion in case a three-dimensional turbulent flow. We consider flow channel with cubic wall-mounted obstacle, and perform large-eddy simulations (LESs) including passive particles injected behind cases low strong inertial effects. also Reynolds-averaged same case, using standard turbulence models, employ ...
