No full textAn Assurance-Based Risk Management Framework for Distributed Systems
No full textThe advent of cloud computing and Internet of Things (IoT) has deeply changed the design and operation of IT systems, affecting mature concepts like trust, security, and privacy. The benefits in terms of new services and applications come at a price of new fundamental risks, and the need of adapting risk management frameworks to properly understand and address them. While research on risk management is an established practice that dates back to the 90s, many of the existing frameworks do not even come close to address the intrinsic complexity and heterogeneity of modern systems. They rather target static environments and monolithic systems thus undermining their usefulness in real-world use cases. In this paper, we present an assurance-based risk management framework that addresses the requirements of risk management in modern distributed systems. The proposed framework implements a risk management process integrated with assurance techniques. Assurance techniques monitor the correct behavior of the target system, that is, the correct working of the mechanisms implemented by the organization to mitigate the risk. Flow networks compute risk mitigation and retrieve the residual risk for the organization. The performance and quality of the framework are evaluated in a simulated industry 4.0 scenario
Active head and cervical range of motion : effect of age in healthy females
No full textSTUDY DESIGN: A study on active cervical range of motion (RoM) in healthy females of different ages. OBJECTIVE: Perform a three-dimensional quantitative analysis of active head-cervical RoM in healthy females to assess the relationship with age. SUMMARY OF BACKGROUND DATA: Age-related variations in active cervical RoM are still partially unknown: some investigations demonstrated that age has no effect whatsoever on the primary movements, whereas other studies found an inverse proportionality between age and cervical RoM. METHODS: Three groups of females were compared: 22 aged 15 to 18 years (adolescents), 25 aged 20 to 30 years (young adults), and 16 aged 35 to 45 years (mid-aged women). Active flexion and extension, lateral bending and axial rotation were recorded via an optoelectronic system. After the mathematical exclusion of thoracic movements, cervical RoM was referred to head local reference system and calculated using the tilt/twist method. Data were compared using analysis of variance. RESULTS: Flexion and extension were larger in the adolescents (137 degrees ) than in the young adults (128 degrees ) and mid-aged women (127 degrees ). Lateral bending had similar ranges in the 3 groups: 103 degrees for adolescents, 101 degrees for young adults, and 100 degrees for mid-aged women. Axial rotation had similar ranges in the adolescents and in the mid-aged women (143 degrees ) and a slightly larger range in the young adults (151 degrees ). Primary movements were always associated with out-of-plane components. CONCLUSION: In healthy females, between 15 and 45 years old, cervical RoMs in the principal planes decrease (except for rotation), but these variations are not statistically significant (P > 0.05)
About the rapidity and helicity distributions of the W bosons produced at LHC
No full textW bosons are produced at LHC from a forward-backward symmetric initial state. Their decay to a charged lepton and a neutrino has a strong spin analysing power. The combination of these effects results in characteristic distributions of the pseudorapidity of the leptons decaying from W and W of different helicity. This observation may open the possibility to measure precisely the W and W rapidity distributions for the two transverse polarisation states of W bosons produced at small transverse momentum. bosons are produced at LHC from a forward-backward symmetric initial state.

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
