Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic
2022
This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.
UAV-Aided Secure Short-Packet Data Collection and Transmission
2023
Benefiting from the deployment flexibility and the line-of-sight (LoS) channel conditions, unmanned aerial vehicle (UAV) has gained tremendous attention in data collection for wireless sensor networks. However, the high-quality air-ground channels also pose significant threats to the security of UAV aided wireless networks. In this paper, we propose a short-packet secure UAV-aided data collection and transmission scheme to guarantee the freshness and security of the transmission from the sensors to the remote ground base station (BS). First, during the data collection phase, the trajectory, the flight duration, and the user scheduling are jointly optimized with the objective of maximizing t…
Service Provisioning and User Association for Heterogeneous Wireless Railway Networks
2017
In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …
Joint Sub-Carrier and Power Allocation for Efficient Communication of Cellular UAVs
2020
| openaire: EC/H2020/857031/EU//5G!Drones Cellular networks are expected to be the main communication infrastructure to support the expanding applications of Unmanned Aerial Vehicles (UAVs). As these networks are deployed to serve ground User Equipment (UEs), several issues need to be addressed to enhance cellular UAVs’ services. In this paper, we propose a realistic communication model on the downlink, and we show that the Quality of Service (QoS) for the users is affected by the number of interfering BSs and the impact they cause. The joint problem of sub-carrier and power allocation is therefore addressed. Given its complexity, which is known to be NP-hard, we introduce a solution based …

Operētājsistēmu interaktīva instalācija no interneta
2015
Mūsdienās operētājsistēmu izplatīšanai tiek izmantots iekšējais tīkls, kas atrodas uzņēmuma iekšienē. Piekļuvei ir nepieciešamas atbilstošas tiesības un tehniskās zināšanas, kas ne visiem piemīt. Darba mērķis ir apvienojot Windows un Linux tehnoloģijas izstrādāt metodoloģiju, kas ļautu gala lietotājam bez tehniskām zināšanām veikt operētājsistēmu instalēšanu no interneta. Darbā izpētīti operētājsistēmu izplatīšanai, industrijā, plaši izmantojamie risinājumi, to metodes, uzbūve, darbība un veikta to salīdzinoša analīze. Praktiskajā daļā tika izstrādāti vairāki skripti instalācijas procesa automatizēšanai un izveidotas instalācijas pakotnes, lietotāja turpmāka darba atvieglošanai, atbilstoši …

Frazeologizmy v demotivatorah
2008
The article presents new compound words, which are frequently a verbal component of internet polycode texts, i.e. demotivators. Demotivators, i.e. pictures combining graphics or photo and ironie commentary, were at first a response to motivational posters, whose task was to encourage people to work or learn. In the virtual world demotivators comment on current events or mock everyday nonsense. They are such a solidified genre that some of the commentaries used in demotivators can be perceived as phraseological neologisms.
Efectos de las consultas boca a boca en redes sociales en la compra de cosméticos en Ecuador.
2022
Las redes sociales han reestructurado el paradigma de la comunicación en el marketing. Investigaciones recientes demuestran que la conducta de consultar reseñas está adquiriendo un rol fundamental en la decisión de compra de los consumidores. En este contexto, el presente estudio desarrolló un marco de investigación para determinar la cadena de relación entre influencia social, credibilidad percibida del boca a boca, adopción del boca a boca e intención de compra aplicada a la industria cosmética del Ecuador. A través de una muestra de 406 consumidores y la aplicación del método de análisis de ecuaciones estructurales, los resultados evidencian el vínculo existente entre las variables plant…
INFORMATION QUALITY PROBLEMS ON WEBSITES
2019
The goal of this publication is to identify and characterize the typical problems with information quality on websites, and to present exemplary remedies for those problems. In this article the information quality problems within their origins, as well as the consequences of using poor-quality information by the Internet user were defined. There were also presented ways of improving information quality - which should facilitate the information needed by producers/authors and the managers/administrators of services in or to find solutions to the remaining problems. The presented varied remedies are not all possible solutions to improving quality in the area of the WWW content and its infrast…
