3-D simulations of flows in the reconstituted lake Karla, Thessaly, Greece
(2010)We report on three-dimensional flow simulations carried out in order to describe the dominant water current patterns in the reconstituted lake Karla. The flow is considered to be generated mainly by wind shear while the ... -
An active sunlight redirection system for daylight enhancement beyond the perimeter zone
(2017)Over the past years, extensive research has been carried out in the creation of working environments that utilize natural light as their primary source of illumination. Transferring glare-free daylight into the core of the ... -
Cross-layer optimized authentication and error control for wireless 3D medical video streaming over LTE
(2017)3D video for tele-medicine applications is gradually gaining momentum since the 3D technology can provide precise location information. However, the weak link for 3D video streaming is the necessary wireless link of the ... -
The effect of shape and orientation on the barrier properties of flake-filled composites: A 3D approach
(2019)We carry out fully three-dimensional (3D) simulations in flake-filled composites with the objective of determining the effect of flake shape and orientation on their barrier properties. Our simulations are carried out in ... -
Fish-eye camera video processing and trajectory estimation using 3d human models
(2014)Video processing and analysis applications are part of Artificial Intelligence. Frequently, silhouettes in video frames lack depth information, especially in case of a single camera. In this work, we utilize a three-dimensional ... -
Non-linear 3D simulation of the construction and impounding of a CFRD
(2008)A general methodology for the non-linear 3D numerical simulation of the phased construction and subsequent reservoir impoundment of a concrete faced rockfill dam built in a narrow canyon is presented. The common characteristic ... -
Numerical study of particle transport in a river with a lateral harbor basin
(2017)In this study, the development and application of two mathematical models used to investigate particle transport in a river with a lateral harbor basin are presented: a two-dimensional depth-averaged hydrodynamic model and ... -
Prediction of collapse of the osteonecrosis of the hip by determining location and size of the lesion: A 2 to 17 years study
(2010)Osteonecrosis of the femoral head is a disease responsible for a large number of arthroplasties in young and active patients in the western world. Prediction of outcome of the disease remains a difficult task. The purpose ... -
Scalable 3D video streaming over P2P networks with playback length changeable chunk segmentation
(2015)3D video distribution over P2P networks has been thought as a promising way for 3D video entering home. The convergence of scalable 3D video coding and P2P streaming can provide diverse 3D experiences for heterogeneous ... -
Shape reconstruction using fisheye and projective cameras
(2016)Reconstructing shape from silhouettes is an interesting topic in computer vision. In the case of projective (pinhole) cameras, this task has been solved with several variations. The increasing use of omnidirectional cameras, ... -
Stability analysis of the simplest Takagi-Sugeno fuzzy control system using circle criterion
(2007)In this paper, we present two sufficient conditions in the frequency domain for the global stability analysis of the simplest Takagi-Sugeno (T-S) fuzzy control system, based on the circle criterion and its graphical ... -
System identification of a R/C bridge based on ambient vibrations and 3D numerical simulations of the entire soil-structure system
(2011)The scope of this paper is to identify the parameters affecting the dynamic response of an existing R/C bridge, based on low ambient amplitude vibration measurements and numerical predictions using complex finite element ... -
Three-dimensional nonlinear dynamic analysis of multi-base seismically isolated structures with uplift potential
(2010)The complexity of modern seismically isolated structures requires tools for fast, accurate and reliable analysis and the ability to capture potential discontinuous phenomena such as isolator uplift and their effects on the ... -
Ultra-real or symbolic visualization? the case of the city through time
(2006)The distinctive character of digital technology has created new conditions of approach and processing. The city as the object of visualization has its own peculiarities as a separate object, notwithstanding the demands ...
