Adopting XML for Large-Scale Information
2011
This book has presented many different ways to encode information in XML format and the purposes for doing so. In this concluding chapter we consider problems related to managing XML information assets and the methods available to address those problems. Approaches for persistently storing XML data can be divided into file storage and database storage, and the research community has been especially active in designing new solutions for XML databases. However, adoption of XML often means massive migration procedures from some legacy data into the XML format; examples of migration cases are given. While describing the problems related to adopting XML, we give examples of the kinds of data fo…
Why Use XML?
2011
Since its inception a decade ago, XML has become a standard technology for software engineers, all Web browsers are able to parse and show XML documents, and huge XML data resources are available from the Internet. Many of the documents are in XHTML, but other XML applications are quite common as well. XML has also become a format that is increasingly common in the files of local disks. This success would not have been possible without collaborative efforts throughout the Web community. Such world-wide collaborative development has included standards, software applications, and case implementations that can serve as models when developing new solutions. In this chapter we consider what ki…

Sociālā tīmekļa datu apkopošana un analīze
2020
Twitter sociālā tīmekļa lietotāju daudzums visā pasaulē arvien palielinās, tāpēc pieaug arī lietotāju izveidoto datu daudzums un lietotāji nenojauš kādi dati īsti tiek dalīti ar citiem. Darba mērķis ir izpētīt sociālā tīmekļa Twitter tvītu metadatu sastāvu, tvītu ievākšanas metodes, publiski pieejamas sistēmas lietotāja profila analīzei un iegūt ieskatu kādu informāciju varētu uzskatīt par lietotājam nedrošu. Darba praktiskajā daļā izveidota tīmekļa vietne, kurā lietotājs var pieteikties sistēmā un pārbaudīt savus pieejamos datus par atrašanos vietu tvītu metadatos, ja atrašanās vietas opcija ir iespējota. Papildus darba praktiskajā daļā izveidota lietotne Twitter Baltijas valstu lietotāju …
Network Capacity Estimators Predicting QoE in HTTP Adaptive Streaming
2022
The aim of adaptive HTTP streaming technology is preserving the best possible video streaming quality for viewers in heterogeneous network conditions. This can be achieved by making multiple quality versions of the video available. Switching between versions during playback should be imperceptible and fluent. The decision about quality-level switching is typically based on network capacity estimation and buffer occupancy, which predict the risk of stalling. Since quality-level switching and stalling are directly evident to the user, they are often classified as influence factors of quality of experience (QoE). In this paper, we observe different network capacity estimators and buffer behavi…
FALCON - joint fair airtime allocation and rate control for DASH video streaming in software defined wireless networks
2020
Software Defined Wireless Networks offer an opportunity to enhance the performance of specific services by applying centralized mechanisms which make use of a global view of the network resources. This paper presents FALCON, a novel solution that jointly optimizes fair airtime allocation and rate recommendations for Server and Network Assisted DASH video streaming, providing proportional fairness among the clients. Since this problem is NP-hard, FALCON introduces a novel heuristic algorithm that is proved to achieve almost optimal results in a practical amount of time. The performance of FALCON is evaluated when used in conjunction with three referent Adaptive Bit Rate strategies (PANDA, BO…
A hardware skin-segmentation IP for vision based smart ADAS through an FPGA prototyping
2017
International audience; In this paper we presents a platform based design approach for fast HW/SW embedded smart Advanced Driver Assistant System (ADAS) design and prototyping. Then, we share our experience in designing and prototyping a HW/SW vision based smart embedded system as an ADAS that helps to increase the safety of car's drivers. We present a physical prototype of the vision ADAS based on a Zynq FPGA. The system detects the fatigue state of the driver by monitoring the eyes closure and generates a real-time alert. A new HW/SW codesign skin segmentation step to locate the eyes/face is proposed. Our presented new approach migrates the skin segmentation step from processing system (S…
La intervención posconflicto en el Derecho internacional: una auditoría de género
2013
Que el conflicto armado tiene un impacto diferenciado de género es harto conocido. Demostrar además que la intervención posconflicto también lo tiene, constituye el objetivo de esta tesis. Por ello, partiendo de la potencialidad del gender mainstreaming o perspectiva transversal de género como herramienta fundamental para la gestión internacional de conflictos y, en línea con los postulados de la resolución 1325 del Consejo de Seguridad de Naciones Unidas sobre mujeres, paz y seguridad de 31 de octubre del año 2000, esta investigación adopta la forma de auditoría de género para trazar, mediante un análisis contextual (primera parte), jurídico (segunda parte) y clínico (tercera parte), la ev…
Students with Severe, Permanent Disabilities and Their Educational Inclusion in Spain
2014
This article analyses the educational inclusion of students with severe and permanent disabilities in the different autonomous communities of the Spanish State. After describing the Spanish socio-economic context, a comparative analysis is carried out based on the following indicators: the conception of severe, permanent disabilities; the regulation framework; responsibility of schooling and provision of services; identification and assessment of flaws; incidence in the population; curricular proposals (model and modalities of support); specific centers and units; human and material resources; the role of families and funding. The analysis of the implemented policies concludes by pointing o…
Aborted quantitative study in the French music industry: the changes of music labels facing streaming
2020
International audience; This paper shows a failed case study of the impact of streaming on labels’ life through the exploitation of three quantitative databases. Streaming is a major external change for the music consumption and music producers. As labels are dealing with both producers and consumers, they may have been hardly impacted by this change. Yet there was a need to identify the changes that streaming brought and its impact for the organizations that decided not to adopt it. The ecology of population framework and the death vs dynamism dyad was supposed to give a clear reading of this phenomenon. In order to identify labels that did not adopt streaming, three databases were tested,…
