Anomaly Detection in Traffic Surveillance Videos Using Deep Learning
2022
In the recent past, a huge number of cameras have been placed in a variety of public and private areas for the purposes of surveillance, the monitoring of abnormal human actions, and traffic surveillance. The detection and recognition of abnormal activity in a real-world environment is a big challenge, as there can be many types of alarming and abnormal activities, such as theft, violence, and accidents. This research deals with accidents in traffic videos. In the modern world, video traffic surveillance cameras (VTSS) are used for traffic surveillance and monitoring. As the population is increasing drastically, the likelihood of accidents is also increasing. The VTSS is used to detect abno…
Digitālā medija zīmola attīstīšana patērētājauditorijā.
2019
Darba tēma: Digitālā medija zīmola attīstīšana patērētājauditorijā. Darba mērķis: Pamatojoties uz teorētiskajām atziņām zinātniskajā literatūrā, kā arī autores veikto pētījumu rezultātiem, izpētīt digitālā mediju zīmola veidojošās komponentes un atšķirīgās īpašības, izvirzot secinājumus un izstrādājot priekšlikumus digitālā mediju zīmola attīstības veicināšanai un lomai patērētāju vidū. Hipotēze: Veiksmīga digitālā medija zīmola attīstība ir tieši saistīta ar patērētāju attieksmi pret produkta funkcionālajiem aspektiem, kā arī pret zīmola lomu un atpazīstamību sabiedrībā kopumā. Darbā ir trīs galvenās nodaļas. Pirmajā nodaļā teorētiski tiek apskatīts zīmola jēdziens un to veidojošie kompone…
Real-Time Photoplethysmography Imaging System
2011
Real-time non-contact photoplethysmography imaging (PPGI) system for high-resolution blood perfusion mapping in human skin has been proposed. The PPGI system comprises of LED lamp, webcam and computer with video processing software. The purpose of this study is to evaluate the reliability of the PPGI system when measuring blood perfusion. The validation study of PPGI and laser-Doppler perfusion imager (LDPI) was performed during local warming of palm skin. Results showed that the amplitude of PPGI increases immediately after warming and well correlated with the mean LDPI amplitude (R=0.92+-0.03, p<0.0001). We found that PPGI technique has good potential for non-contact monitoring of blood p…
Dažādi videospēļu žanri kā literāri darbi
2018
Žanrus var izmantot, lai efektīvi kategorizētu darbus dažādās sfērās, taču šī pētījuma uzsvars ir uz salīdzinājumu tieši starp divām konkrētām nozarēm – sen pastāvošo daiļliteratūru un nesen izveidojušos videospēļu industriju. Mērķis ir analizēt videospēles no literāra skatupunkta, nosakot, vai starp abiem pastāv līdzības, un kādas tās ir. Šī pētījuma fokusā ir pieci literāro žanru veidi un to iezīmes, kam seko to meklējums un analīze sešās videospēlēs. Lai iegūtu rezultātus, tika pielietoti žanru pētījumi, interpretēšana, naratīva salīdzinājumi un analīze. Pētījuma iznākums liecināja par to, ka lielākā daļa izvēlēto literāro žanru īpašību bija sastopamas arī atbilstošajos videospēļu žanros…
Nursing students' perceptions of a video-based serious game's educational value: A pilot study.
2018
Abstract Background Despite an increasing number of serious games (SGs) in nursing education, few evaluation studies specifically address their educational value in terms of face, content, and construct validity. Objectives To assess nursing students' perceptions of a video-based SG in terms of face, content, and construct validity. In addition, the study assessed perceptions of usability, individual factors, and preferences regarding future use. Design A pilot study was conducted. Setting and Participants An SG prototype was implemented as part of two simulation courses in nursing education: one for home health care and one for hospital medical-surgical wards. The SG aimed to teach clinica…
Video Streaming Distribution in VANETs
2011
Streaming applications will rapidly develop and contribute a significant amount of traffic in the near future. A problem, scarcely addressed so far, is how to distribute video streaming traffic from one source to all nodes in an urban vehicular network. This problem significantly differs from previous work on broadcast and multicast in ad hoc networks because of the highly dynamic topology of vehicular networks and the strict delay requirements of streaming applications. We present a solution for intervehicular communications, called Streaming Urban Video (SUV), that 1) is fully distributed and dynamically adapts to topology changes, and 2) leverages the characteristics of streaming applica…
Re-ventriculostomy for treatment of obstructive hydrocephalus in cases of stoma dysfunction.
2002
In this article, 12 re-ventriculostomies in the treatment for obstructive hydrocephalus are described. The etiology of the hydrocephalus was a benign aqueductal stenosis in 9 patients, a tumor around the aqueduct in 2 patients and intraventricular bleeding in one patient. In all cases the initial ventriculostomy was successful, but after a time interval of 2 weeks to 6 years the patients developed similar clinical symptoms as preoperatively. In all except one case the radiological findings spoke in favour of stoma closure. Intraoperatively the stoma was completely closed in 9 patients and in 3 patients a subtotal closure was observed. In all cases a re-ventriculostomy was performed bluntly …
Realistic model of compact VLSI FitzHugh–Nagumo oscillators
2013
In this article, we present a compact analogue VLSI implementation of the FitzHugh–Nagumo neuron model, intended to model large-scale, biologically plausible, oscillator networks. As the model requires a series resistor and a parallel capacitor with the inductor, which is the most complex part of the design, it is possible to greatly simplify the active inductor implementation compared to other implementations of this device as typically found in filters by allowing appreciable, but well modelled, nonidealities. We model and obtain the parameters of the inductor nonideal model as an inductance in series with a parasitic resistor and a second order low-pass filter with a large cut-off freque…

Video arte a Catania.
2014
L'articolo propone una riflessione sulla manifestazione, tenutasi nel 2014 a Catania presso lo spazio Ritmo, «Cinema D’essai», rassegna particolarmente interessante la cui protagonista assoluta è stata l’arte del video. Filo conduttore dei lavori in mostra, realizzati da artisti tanto giovani quanto apprezzati che dedicano parte della loro ricerca alla video arte, è non soltanto il medium ma anche la riflessione sul medium stesso.
