Tracing battery usage for second life market with a blockchain-based framework

2021

This work describes the design of a platform based on a permissioned blockchain for sharing relevant information among the actors involved in grid service provision programs. The information collected by a proprietary monitoring on-board system accessing the central unit of the Electric Vehicle, EV, is then sent to a dropbox folder owned by the car owner and then written on a blockchain platform. The platform could be supplied from similar data from the grid operator collected on the grid during the provision of services. In this way data can be validated and used for tracing the health status of the EV's battery. The design of customized smart contract allows to acquire the profiles of bat…

MODELLING USER UNCERTAINTY FOR DISCLOSURE RISK AND DATA UTILITY

2002

In this paper we show how a simple model that captures user uncertainty can be used to define suitable measures of disclosure risk and data utility. The model generalizes previous results of Duncan and Lambert.1 We present several examples to illustrate how the new measures can be used to implement existing optimality criteria for the choice of the best form of data release.

Predicting mobile apps spread: An epidemiological random network modeling approach

2017

[EN] The mobile applications business is a really big market, growing constantly. In app marketing, a key issue is to predict future app installations. The influence of the peers seems to be very relevant when downloading apps. Therefore, the study of the evolution of mobile apps spread may be approached using a proper network model that considers the influence of peers. Influence of peers and other social contagions have been successfully described using models of epidemiological type. Hence, in this paper we propose an epidemiological random network model with realistic parameters to predict the evolution of downloads of apps. With this model, we are able to predict the behavior of an app…

Decoding Children's Social Behavior

2013

We introduce a new problem domain for activity recognition: the analysis of children's social and communicative behaviors based on video and audio data. We specifically target interactions between children aged 1-2 years and an adult. Such interactions arise naturally in the diagnosis and treatment of developmental disorders such as autism. We introduce a new publicly-available dataset containing over 160 sessions of a 3-5 minute child-adult interaction. In each session, the adult examiner followed a semi-structured play interaction protocol which was designed to elicit a broad range of social behaviors. We identify the key technical challenges in analyzing these behaviors, and describe met…

Objetivos: Análisis bibliométrico de los trabajos publicados por RELIEVE en los últimos 15 años; que se corresponden con los procesados por Emerging Sources Citation Index (ESCI), una nueva base de datos de Web of Science (WOS) que pretende corregir la deficiente cobertura de las revistas nacionales de algunos países. Método: Fuente de datos: 195 artículos de RELIEVE recogidos en ESCI. Análisis: Se analizaron las 7.408 referencias emitidas por los 195 trabajos. Igualmente se analizaron las 599 citas recibidas por la revista. Temáticas cubiertas: se volcaron las Author-Keywords de los 195 trabajos en la herramienta de software VOSviewer. Resultados: las citas emitidas arrojan un promedio por…

A Bibliometric Analysis of the HICSS Software Technology Track

2020

The HICSS Software Technology track has a long tradition and many papers have been published as part of its history. Its impact in terms of citations, paper contributions, author share and community impact does not yet seem to have been investigated, though. In particular, software technology has evolved, and as it stands, it is of primary importance for mobile computing, the Internet-of-Things and Cyber-physical Systems. Hence, the development of these topics and the related impact of this track are of particular interest. In this paper, we present a bibliographic analysis as a first step towards such an investigation. We found that the history of the track is indeed noteworthy. Our result…

Big Data Processing in the ATLAS Experiment: Use Cases and Experience

2015

Abstract The physics goals of the next Large Hadron Collider run include high precision tests of the Standard Model and searches for new physics. These goals require detailed comparison of data with computational models simulating the expected data behavior. To highlight the role which modeling and simulation plays in future scientific discovery, we report on use cases and experience with a unified system built to process both real and simulated data of growing volume and variety.

Big Data in metagenomics: Apache Spark vs MPI.

2020

The progress of next-generation sequencing has lead to the availability of massive data sets used by a wide range of applications in biology and medicine. This has sparked significant interest in using modern Big Data technologies to process this large amount of information in distributed memory clusters of commodity hardware. Several approaches based on solutions such as Apache Hadoop or Apache Spark, have been proposed. These solutions allow developers to focus on the problem while the need to deal with low level details, such as data distribution schemes or communication patterns among processing nodes, can be ignored. However, performance and scalability are also of high importance when…
