A Novel Approach for Accelerating Bitstream Relocation in Many-core Partially Reconfigurable Applications
2013
International audience; Partial Bitstream Relocation (PBR) has been introduced in recent years, as a means to overcome the limitations of the traditional Xilinx Partial Reconfiguration flow, particularly in terms of the limited module placement, a fact that can greatly reduce the memory footprint of applications which require multiple implementations of the same module... However, PBR consumes scarce resources in hardware implementations, and introduces a prohibitive time overhead when done in software. This is particularly true in applications such as large scalable systems, which typically require multiple copies of the same module to accelerate a task, but in which the relocation time ov…
Location-Aware Mobile Intrusion Detection with Enhanced Privacy in a 5G Context
2010
Published version of an article from the journal: Wireless Personal Communications. The original publication is available at Spingerlink. http://dx.doi.org/10.1007/s11277-010-0069-6 The paper proposes a location-aware mobile Intrusion Prevention System (mIPS) architecture with enhanced privacy that is integrated in Managed Security Service (MSS). The solution is envisaged in a future fifth generation telecommunications (5G) context with increased but varying bandwidth, a virtualised execution environment and infrastructure that allows threads, processes, virtual machines and storage to be migrated to cloud computing services on demand, to dynamically scale performance and save power. 5G mob…
Achieving agility and quality in product development -an empirical study of hardware startups
2020
Context: Startups aim at scaling their business, often by developing innovative products with limited human and financial resources. The development of software products in the startup context is known as opportunistic, agility-driven, and with high tolerance for technical debt. The special context of hardware startups calls for a better understanding of state-of-the-practice of hardware startups’ activities. Objective: This study aimed to identify whether and how startups can achieve product quality while maintaining focus on agility. Method: We conducted an exploratory study with 13 hardware startups, collecting data through semi-structured interviews and analysis of documentation. We pro…
“Nos inventamos un mundo que no existía”. Una profesión de riesgo.
2019
Since the end of Franco's dictatorship, editorial censorship has been an object of interdisciplinary study that has been incorporating, to the initial analysis of the constitution and nature of censorship, the study of a variety of case studies that are resizing the phenomenon. On the one hand, in the context of memory studies, it is necessary to analyze what effects censorship had on the configuration of cultural memory. On the other hand, censorship has a considerable effect on publishing strategies, both in itself and because it fosters self-censorship and countercensorship. In particular, this article explores the work of women publishers who, in the Barcelona of the 1960s and 1970s, op…
Diversity in search strategies for ensemble feature selection
2005
Ensembles of learnt models constitute one of the main current directions in machine learning and data mining. Ensembles allow us to achieve higher accuracy, which is often not achievable with single models. It was shown theoretically and experimentally that in order for an ensemble to be effective, it should consist of base classifiers that have diversity in their predictions. One technique, which proved to be effective for constructing an ensemble of diverse base classifiers, is the use of different feature subsets, or so-called ensemble feature selection. Many ensemble feature selection strategies incorporate diversity as an objective in the search for the best collection of feature subse…
Practices and Knowledge: Philosophy of Biomedicine, Governance and Citizen Participation
2018
The present chapter addresses the emergence of new forms of governance and citizen participation in the context of certain biotechnologies. On the basis of three case studies, we have mapped different models of public participation in health issues (especially health activism and Internet users, though not exclusively): identifying and analyzing actors, their mutual relationships (mainly those between "patients"/activists groups and the biomedical community), strategies and forms of participation, the exchange and circulation of "expert/lay" knowledge (and the role of the Internet in these processes), and the different activities and forms of knowledge production by "lay" citizen groups (or…
Public Governance Principles in General Education School Management of Latvia
2015
In contemporary world the effect of globalisation and information technologies cause transformational processes of states` public management that promote the application of new managament approaches and principles in public institution management.The changes in the public managament have effected and still effects processes of management also in education. The increase of school autonomy, a stronger focus on the process of education and its results created the need to expand the application of contemporary public management principles also in the managament of education institutions. The main goal of the report is to analyze the principles of public management and their implementation in th…
Problematic internet use prior to and during the COVID-19 pandemic
2021
The health and socio-economic challenges arising from the COVID-19 pandemic have led to greater reliance on the internet to meet basic needs and responsibilities. Greater engagement in online activities may have negative mental and physical health consequences for some vulnerable individuals, particularly under mandatory self-isolation or ‘lockdown’ conditions. The present study investigated whether changes in levels of involvement in online activities during the COVID-19 pandemic (i.e., watching TV series,online sexual activities, video games, social networks, gambling, online shopping, and instant messaging) were associated with problematic internet use, as well as whether certain psychol…
An efficient hardware implementation of Diamond Search motion estimation using CAL dataflow language
2011
Motion estimation represents a key module in video compression. The Reconfigurable Video Coding context (RVC) requires proposing a flexible solution for motion estimation. The motion estimation performance should be modified to fit with the user or the environment's constraints. Depending on the required performances fixed by the application, a full search is sometimes not suitable, hence, alternative fast/reduced solutions should be considered. In this paper, an efficient Diamond Search motion estimation, described in RVC-CAL actor language, is introduced. Starting from a high level description based CAL language, an automatic translation of the proposed CAL module to HDL is performed. Thi…
A Comparison Between Japanese and French Cost Management – Contingency and Institutional Perspectives
2018
From an historical perspective, management accounting is a very recent phenomenon (see Johnson & Kaplan, 1987) and is culturally grounded in a few old-industrialized countries, in Europe: Germany, United-Kingdom, France, but also in Japan and in the United-States. Notwithstanding the cultural dominance of English-speaking countries on management, non-English speaking countries keep strong institutional and cultural roots that still influence their ways of managing companies. This is the case when looking at management accounting and more especially at cost accounting and cost management practices (now cost accounting/management). This paper, based on contingency and institutional frameworks…
