Video Delivery in Dense 5G Cellular Networks
(2017)One of the main challenges for mobile network operators today is the efficient delivery of mobile VoD services. In order to satisfy their requirements, we must revolutionize the way we manage the densely deployed resources ... -
Video delivery over heterogeneous cellular networks: Optimizing cost and performance
(2014)Video delivery to mobile users is one of the largest challenges that network operators face today. In this work we consider a heterogeneous cellular network with storage capable small-cell base stations, and study this ... -
Video Laryngoscopy Improves Intubation Times With Level C Personal Protective Equipment in Novice Physicians: A Randomized Cross-Over Manikin Study
(2021)Background: The use of video laryngoscopes by novice physicians may improve first-pass success rates compared with direct laryngoscopy. Objective: The aim of the present study was to assess whether time to intubation, ... -
Video-aware multicast opportunistic routing over 802.11 two-hop mesh networks
(2014)In this paper, we propose and characterize the performance of a novel video-aware Opportunistic Routing (OR) algorithm for multicast, using a one-hop and two-hop forwarding scheme in 802.11 mesh networks. We believe that ... -
Video-Aware Multicast Opportunistic Routing over 802.11 Two-Hop Mesh Networks
(2017)Opportunistic routing benefits from the broadcast nature of wireless communication and outperforms the packet losses occurring in a wireless environment, especially in the case of multicast. In this work, we present and ... -
Video-aware relay selection in single-carrier and OFDM wireless systems
(2014)In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ... -
Video-aware relay selection in single-carrier and OFDM wireless systems
(2016)In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. ... -
Video-aware time-domain resource partitioning in heterogeneous cellular networks
(2015)Heterogenous cellular networks (HCN) consist of macrocells and small cells that are overlaid in the same geographical area. Hence, is critical that the high power macrocell shuts off its transmissions for a fraction of the ... -
Video-Based Eye Blink Identification and Classification
(2022)Blink detection and classification can provide a very useful clinical indicator, because of its relation with many neurological and ophthalmological conditions. In this work, we propose a system that automatically detects ... -
Video-surveillance and context aware system for activity recognition
(2010)Fall detection is the main issue in design an AAL system for elderly. This paper describes an algorithm for vision and audio fall detection. The main problem with video surveillance is the distinction of a fall from similar ... -
Vidian canal and sphenoid sinus: an MDCT and cadaveric study of useful landmarks in skull base surgery
(2020)Purpose: To present the anatomical variations of vidian canal (VC) and sphenoid sinus (SS), relative to other anatomical landmarks of skull base area, which may be helpful for safer surgical approach to this area. Materials: ... -
Views and experiences of persons with chronic diseases about strategies that aim to integrate and re-integrate them into work: A systematic review of qualitative studies
(2018)The effectiveness of strategies targeting professional integration and reintegration strongly depends on the experiences of participants. The aim of this systematic literature review is to synthesize European qualitative ... -
VIIRS lunar radiance removal by Dark Object Subtraction
(2019)The removal of lunar radiance in Visible Infrared Imaging Radiometer Suite (VIIRS) - Day/Night Band (DNB) images is explored based on the Dark Object Subtraction method. A Dark Object is selected and the difference of the ... -
VIM-1 metallo-beta-lactamase in Acinetobacter baumannii
(2006)In 2004 and 2005, 5 metallo-beta-lactamase (MBL)-positive Acinetobacter baumannii isolates were found in 2 Greek hospitals. Isolates were unrelated and carried bla(VIM-1) in a class 1 integron; bla(OXA-51-) and bla(OXA-58-like) ... -
VIM-1 metallo-β-lactamase in Acinetobacter baumannii
(2006)In 2004 and 2005, 5 metallo-β-lactamase (MBL)-positive Acinetobacter baumannii isolates were found in 2 Greek hospitals. Isolates were unrelated and carried blaVIM-1 in a class 1 integron; blaOXA-51- and blaOXA-58-like ... -
VIM-12, a novel plasmid-mediated metallo-β-lactamase from Klebsiella pneumoniae that resembles a VIM-1/VIM-2 hybrid
(2005)A transferable plasmid from Klebsiella pneumoniae carried a class 1 integron containing blaVIM-12, a novel blaVIM-type gene, flanked by two copies of aacA7. blaVIM-12 was clustered between bla-VIM-1 and bla-VIM-2 and ...
