Operational cloud screening service for Sentinel-2 image time series
2015
This paper deals with the development and implementation of a cloud screening algorithm for image time series, with the focus on the forthcoming Sentinel-2 satellites to be launched under the ESA Copernicus Programme. The proposed methodology is based on kernel ridge regression and exploits the temporal information to detect anomalous changes that correspond to cloud covers. The huge data volumes to be processed when dealing with high temporal, spatial, and spectral resolution datasets motivate the implementation of the algorithm within distributed computer resources. In consequence, an operational cloud screening service has been specifically designed and implemented in the frame of the Se…
Cloud Based Cross-system Integration for Small and Medium-sized Enterprises
2017
The usage of information technology (IT) is one of the major factors for ensuring the growth and competitiveness of enterprises, as well as it also benefits the effective knowledge management within the organisation.There are large-scale knowledge management systems (KMS) covering the full functionality for facilitating the effectiveness and productivity of employees. These systems are frequently integrated into other organisation's management systems. But the most of the small and medium-sized enterprises (SMEs) cannot afford to use these KMS, and also the full functionality of these KMS is not necessary for them. Thus, the solution is to combine the parts of cloud based knowledge manageme…
Business Intelligence and Analytics in Small and Medium-sized Enterprises: A Systematic Literature Review
2017
Despite much interest in business intelligence and analytics (BI&A), empirical research shows that small and medium-sized enterprises (SMEs) are still lagging behind in the proliferation of BI&A. However, there are no studies found on literature reviewing research on BI&A in SMEs. This paper collects, categorizes, synthesizes, and analyzes 62 articles related to BI&A in SMEs. The identified research topics being addressed in BI&A include: BI&A components, BI&A solutions, Mobile BI&A, Cloud BI&A, BI&A application, BI&A adoption, BI&A implementation, and BI&A benefits. Further, research gaps and directions for future research are presented to facilitate the progression of BI&A in SMEs researc…
Value networks in cloud computing
2011
PurposeThe purpose of this paper is to examine value networks in cloud computing. It demonstrates the kinds of value offered by such networks to firms within a given network, and considers how and why the network may change over time.Design/methodology/approachThe paper reports on a longitudinal case study, including a total of seven semi‐structured open‐ended interviews, conducted with five informants from the case firm.FindingsIt was found that cooperation in value networks provides not merely financial benefits, but also knowledge, among other intangible benefits. Value networks should be evaluated as a whole, since there may be indirect connections – i.e. the value comes not directly fr…
Understanding cloud computing adoption issues: A Delphi study approach
2016
An exploratory ranking-type Delphi study and follow-up interviews were conducted.Important cloud computing adoption issues are identified, categorized and ranked.Three subpanels top-ranked issues from security, strategy and legal categories.A framework of inhibitors and drivers for cloud computing adoption is proposed.Recommendations to assist decision-makers in cloud computing adoption are proposed. This research paper reports on a Delphi study focusing on the most important issues enterprises are confronted with when making cloud computing (CC) adoption decisions. We had 34 experts from different domain backgrounds participated in a Delphi panel. The panelists were IT and CC specialists r…
Dynamic Computation Offloading Scheme for Fog Computing System with Energy Harvesting Devices
2020
Fog computing is considered as a promising technology to meet the ever-increasing computation requests from a wide variety of mobile applications. By offloading the computation-intensive requests to the fog node or the central cloud, the performance of the applications, such as energy consumption and delay, are able to be significantly enhanced. Meanwhile, utilizing the recent advances of social network and energy harvesting techniques, the system performance could be further improved. In this paper, we take the social relationships of the energy harvesting MDs into the design of computational offloading scheme in fog computing. With the objective to minimize the social group execution cost…
Des Translators neue Kleider. Die Translationwirtschaft in Zeiten von Digitalisierung, Datafizierung und Big Data Management
2017
Abstract The Internet of things will influence all professional environments, including translation services. Advances in machine learning, supported by accelerating improvements in computer linguistics, have enabled new systems that can learn from their own experience and will have repercussions on the workflow processes of translators or even put their services at risk in the expected digitalized society. Outsourcing has become a common practice and working in the cloud and in the crowd tend to enable translating on a very low-cost level. Confronted with promising new labels like Industry 4.0 and Work 4.0, professional freelance translators will have to organize themselves as smart office…
The cloud of Thecla and the construction of her character as a virgin (παρθένος), martyr (μάρτυς) and apostle (ἀπόστολος)
2019
In the Acts of Paul and Thecla (APTh) a cloud appears in the most important scenes of the tale. This motif is used to highlight the protection offered by God on behalf of the young woman and echoes that cloud appearing in Exodus guiding and protecting the Israelites. Thanks to these kinds of echoes, the author of the APTh tries to establish a connection between both scenes in his readers’ minds and builds, at the same time, the character of Thecla, portrayed as a virgin, a martyr or an apostle in different scenes of the narration. En los Hechos de Pablo y Tecla (APlTh) aparece una nube en algunas de las escenas más importante de la narración. Este motivo es utilizado para resaltar la protec…
Carbon monoxide detection
2019
Carbon monoxide (CO) is a particularly toxic gas, and the CO poisoning is the leading cause of fatal poisoning in the world. One solution to deal with this dangerous gas is to exploit the advantages given to us by the applications and the technology advances in internet of things (IoT). In this context, we propose to integrate carbon monoxide detection objects to the internet, as part of civil protection intervention applications in case of detection of carbon monoxide to avoid poisoning. To do this, we propose a typical IoT architecture to manage the alerts sent to civil protection in the event of detection of carbon monoxide (CO). The architecture is based on the Message Queue Telemetry T…
