SMOS-IC: An Alternative SMOS Soil Moisture and Vegetation Optical Depth Product
2017
© 2017 by the authors. The main goal of the Soil Moisture and Ocean Salinity (SMOS) mission over land surfaces is the production of global maps of soil moisture (SM) and vegetation optical depth (τ) based on multi-angular brightness temperature (TB) measurements at L-band. The operational SMOS Level 2 and Level 3 soil moisture algorithms account for different surface effects, such as vegetation opacity and soil roughness at 4 km resolution, in order to produce global retrievals of SM and τ. In this study, we present an alternative SMOS product that was developed by INRA (Institut National de la Recherche Agronomique) and CESBIO (Centre d'Etudes Spatiales de la BIOsphère). One of the main go…
FPGA-based Acceleration of Detecting Statistical Epistasis in GWAS
2014
Abstract Genotype-by-genotype interactions (epistasis) are believed to be a significant source of unexplained genetic variation causing complex chronic diseases but have been ignored in genome-wide association studies (GWAS) due to the computational burden of analysis. In this work we show how to benefit from FPGA technology for highly parallel creation of contingency tables in a systolic chain with a subsequent statistical test. We present the implementation for the FPGA-based hardware platform RIVYERA S6-LX150 containing 128 Xilinx Spartan6-LX150 FPGAs. For performance evaluation we compare against the method iLOCi[9]. iLOCi claims to outperform other available tools in terms of accuracy.…
Item Response Trees: a recommended method for analyzing categorical data in behavioral studies
2015
Behavioral data are notable for presenting challenges to their statistical analysis, often due to the difficulties in measuring behavior on a quantitative scale. Instead, a range of qualitative alternative responses is recorded. These can often be understood as the outcome of a sequence of binary decisions. For example, faced by a predator, an individual may decide to flee or stay. If it stays, it may decide to freeze or display a threat and if it displays a threat, it may choose from several alternative forms of display. Here we argue that instead of being analyzed using traditional nonparametric statistics or a series of separate analyses split by response categories, this kind of data ca…
Extension du domaine du sacré
2013
Faisant le constat qu’il releve d’un monde aujourd’hui completement revolu, Paul Ricœur (1974 : 71) ecrivait : « Le sacre est l’archaique ». Demarche bien temeraire, donc, celle d’engager Questions de communication dans un debat referme sur le passe, voire depasse. La discussion serait close et le sujet entendu. Tournons la page. Pourtant le sacre reste d’une etonnante acuite. Il y a quelques annees, il trouvait encore a s’exposer dans ce temple de la creation moderne et de l’avant-garde qu’e...
A Conceptual Model for the IT-supported International Subsidiary Establishment Process
2004
This study examines how the IT-supported international subsidiary establishment process can be implemented. An in-depth literature review uncovered that there is a significant lack of literature to guide managers about how to execute the establishment process of a subsidiary through the support of various IT-tools. This study, by answering the research question “What are the phases in the establishment of a subsidiary through IT-support and how have the phases been executed?” introduces a conceptual model for the IT-supported international subsidiary establishment process. The research findings are useful for both practice and further research. peerReviewed
The Comparison of Software Reliability Assessment Models
2015
Abstract The reliability of the software represents one of the most important attributes of software quality, and the estimation of the reliability of the software is a problem hard to solve with accuracy. Nevertheless, in order to manage the quality of the software and of the standard practices in an organization, it is important to achieve an estimation of the reliability as accurate as possible. In the present work there are described the principles and techniques which underlie the estimation of the reliability of the software, starting from the definition of the concepts which express the attributes of software quality. It is taken into account the issue of the estimation of a software…
Bibliometrics applied to gamification as a digital learning strategy
2019
Este trabajo se interesa por un tema de actualidad como es la gamificación en educación, una interesante estrategia didáctica para responder a los alarmantes datos sobre fracaso y abandono escolar obtenidos año tras año en las pruebas diagnósticas realizadas en el ámbito europeo. A través del estudio bibliométrico de la producción científica se ha analizado las principales tendencias en gamificación, como práctica mediada por la tecnología en las aulas de las diferentes etapas educativas, a través de 137 documentos alojados en la base de datos Scopus y publicados en la última década. En los resultados se revela que el número de documentos se ha incrementado notablemente en los últimos años;…
Accessibility of Cultural Heritage in the Virtual Environment of Latvia Memory Institutions
2014
The aim of research is to evaluate the level of e-service provision in digital collections created by memory institutions (libraries and archives) of Latvia. The problem under study is as follows: digital collections have insufficient usability due to lack of appropriate e-services. The empirical basis for research is e-services of digital collections created by national and regional level libraries, as well as the National Archives of Latvia. The evaluation of e-services is based on 14 indicators within 7 categories: visibility, search, reference, personalization, user participation, instructions, and document delivery. The analysis reveals that the level of eservice development is quite l…
Balanced Large Scale Knowledge Matching Using LSH Forest
2015
Evolving Knowledge Ecosystems were proposed recently to approach the Big Data challenge, following the hypothesis that knowledge evolves in a way similar to biological systems. Therefore, the inner working of the knowledge ecosystem can be spotted from natural evolution. An evolving knowledge ecosystem consists of Knowledge Organisms, which form a representation of the knowledge, and the environment in which they reside. The environment consists of contexts, which are composed of so-called knowledge tokens. These tokens are ontological fragments extracted from information tokens, in turn, which originate from the streams of information flowing into the ecosystem. In this article we investig…
Factory Workers' Ordinary User Experiences: An Overlooked Perspective
2018
Experiences with technology often are described as exciting and outstanding, for instance, in relation to novel technologies at home or at work. In this article, we aim to complement this perspective by emphasizing people’s mundane and ordinary experiences with technology, that is, unremarkable experiences happening in the background of people’s attention. Based on our investigations of user experience in a semiconductor factory, we show how such ordinary experiences are substantial in workers’ everyday interactions with technology, which are mainly shaped by repetitive activities and routines. However, current conceptions of user experience seem to overlook those mundane experiences and ho…
