The development of adolescents' comprehension-based Internet reading activities
2018
Abstract Internet-based reading involves integration and evaluation of information from different sources and different formats, but also requires fluent navigation skills for adequate comprehension. The effects of linguistic (word decoding and comprehension-based print reading) and non-cognitive factors (reading frequency and self-efficacy) have extensively been studied for print reading; we know very little about their role in Internet reading, which is our focus in this study. 558 students from grades 7 to 10 performed a set of comprehension-based Internet reading tasks on a computer, while their navigation and comprehension scores were recorded. They were also assessed on print reading …
IT-Enabled Effective and Efficient International Technology Transfer for SMEs
1999
This study describes the introduction of a new international technology transfer paradigm. The essence of this new paradigm is based on IT-enabled ITT process. The modern business environment is overwhelmed by increased competition and uncertainty, rapid changes in technology, a diminished technology life cycle, and the advent of more powerful, cheaper and easier to use ITs. These factors reinforce the need for the investigation of globalization possibilities of western SMEs via the utilization of high potential ITs in ITT. The ITT process has become more efficient as new ITs are integrated with SMEs’ existing information systems. This type of integration also eliminates many barriers of di…
Predictive and Evolutive Cross-Referencing for Web Textual Sources
2017
International audience; One of the main challenges in the domain of competitive intelligence is to harness important volumes of information from the web, and extract the most valuable pieces of information. As the amount of information available on the web grows rapidly and is very heterogeneous, this process becomes overwhelming for experts. To leverage this challenge, this paper presents a vision for a novel process that performs cross-referencing at web scale. This process uses a focused crawler and a semantic-based classifier to cross-reference textual items without expert intervention, based on Big Data and Semantic Web technologies. The system is described thoroughly, and interests of…
SEGMENTACIÓN DEL COMPRADOR A DISTANCIA: UN ANÁLISIS DE LOS MEDIOS INTERNET Y TELEVISIÓN /
2005
La aparición de nuevos canales de venta como Internet y la Televisión está generando nuevas oportunidades de mercado para las empresas y está cambiando los hábitos de compra de los consumidores. No obstante, debido a la escasa experiencia de consumidores y empresas en este nuevo medio, la influencia del perfil del consumidor en la decisión de compra en los entornos virtuales es todavía desconocida. El objetivo del presente trabajo es analizar y comparar el perfil sociodemográfico y comportamental de los compradores que utilizan los medios Internet y Televisión, con el fin de identificar los segmentos prioritarios de consumidores para las empresas interesadas en la realización de una campaña…
A Guaranteed performance of a green data center based on the contribution of vital nodes
2016
International audience; In order to satisfy the need for the critical computing resources, many data center architectures proposed to house a huge number of network devices. These devices are used to achieve the highest performance in case of full utilization of the network. However, the peak capacity of the network is rarely reached. Consequently, many devices are set into idle state and cause a huge energy waste leading to a non-proportionality between the network load and the energy consumed. In this paper, we propose a power-aware routing algorithm that saves energy consumption with a negligible trade-off on the performance of the network. The idea is to keep active only the source and …
Achieving energy efficiency in data centers with a performance-guaranteed power aware routing
2017
Nowadays, data centers are designed to offer the highest performance in case of high traffic load and peak utilisation of the network. However, in a realistic data center environment, the peak capacity of the network is rarely reached and the average utilisation of devices varies between 5% and 25% which results into a huge loss of energy since most of the time links and servers are idle or under-utilized. The high impact of this wasted power on environmental effects, energy needs and electricity costs raised the concerns to seek for an efficient solution to make data centers more power effective while keeping the desired quality of service. In this paper, we propose a power-aware routing a…
Computation of Yvon-Villarceau circles on Dupin cyclides and construction of circular edge right triangles on tori and Dupin cyclides
2014
Ring Dupin cyclides are non-spherical algebraic surfaces of degree four that can be defined as the image by inversion of a ring torus. They are interesting in geometric modeling because: (1) they have several families of circles embedded on them: parallel, meridian, and Yvon-Villarceau circles, and (2) they are characterized by one parametric equation and two equivalent implicit ones, allowing for better flexibility and easiness of use by adopting one representation or the other, according to the best suitability for a particular application. These facts motivate the construction of circular edge triangles lying on Dupin cyclides and exhibiting the aforementioned properties. Our first contr…
Location of navigation menus in websites: an experimental study with Arabic users
2015
Published online: 31 October 2015 While Arabic users represent by far the fastest growing language population on the Internet, research about how the peculiarities of Arabic language may shape users’ web interactions is still scarce. The preferences of Arabic users for menu location in websites have been studied. Two competing arguments have been proposed regarding the best location of menus in websites: conventional design (navigation menu should be placed on that side where users expect it based on previous experience) and reading direction (navigation menu should be placed on that side where readers are used to start off reading, so that the navigation menu is likely to be attended first…
Information Integration Platform for Patient-Centric Healthcare Services: Design, Prototype and Dependability Aspects
2014
Published version of an article in the journal: Future Internet. Also available from the publisher at: http://dx.doi.org/10.3390/fi6010126 Open Access Technology innovations have pushed today’s healthcare sector to an unprecedented new level. Various portable and wearable medical and fitness devices are being sold in the consumer market to provide the self-empowerment of a healthier lifestyle to society. Many vendors provide additional cloud-based services for devices they manufacture, enabling the users to visualize, store and share the gathered information through the Internet. However, most of these services are integrated with the devices in a closed “silo” manner, where the devices can…
Performance analysis of underlay two-way relay cooperation in cognitive radio networks with energy harvesting
2018
Abstract Cognitive radio and energy harvesting are two important approaches to solve the problem of spectrum scarcity and energy constraint in wireless communications. In this work, we study a two-way relay cooperation scheme in underlay cognitive radio networks (CRNs) with energy harvesting in which two secondary users exchange information via an energy harvesting relay node. Since the relay node collects energy from the received signals and utilizes it to forward the information, the secondary transmission power can be markedly reduced. Therefore the interference of the secondary network to the primary network can be substantially reduced. We derive the outage probability of the secondary…
