An Overview of 5G Slicing Operational Business Models for Internet of Vehicles, Maritime IoT Applications and Connectivity Solutions

2021

Identification of ecosystems and Business Models (BM) is an important starting point for new complex system development. The definition of actor (or stakeholder) roles and their interactions (at both business and technical levels), together with target scenarios and use cases, provide essential input information for further system requirement collection and architecture specification. The powerful and flexible Fifth Generation (5G) network slicing technology, which is capable of creating virtually isolated and logically parallel networks, enables a large range of complex services and vertical applications. Although various terminologies and models have been proposed in recent years for BMs …

Basics of Ion Scattering in Nanoscale Materials

2009

Energetic ions interact with materials by collisions with the nuclei and electrons of the atoms that make up the material. In these collisions, energy and momentum is transferred from the projectile particle, which is a moving atom or ion, to the target particles (atomic nucleus or electron). Each collision leads to a slowing down of the moving projectile and also a deflection of the trajectory that gives rise to the term scattering, which is often used synonymously to describe the energy transfer process.

The dream of Abha. Note su una ricerca universitaria

2019

Il testo conduce una riflessione sugli esiti della ricerca condotta (in ambito universitario) sull'architettura islamica in Arabia Saudita. Si tratta, anzitutto, di un lavoro di studio e di riconoscimento dei caratteri tradizionali riguardanti lo spazio, il linguaggio, ma anche gli insediamenti che hanno caratterizzato il Paese nella sua storia recente e fino al tempo attuale. Inoltre, a partire dalle condizioni tramandate dalla dalla tradizione, si propone un ragionamento secondo il quale il progetto di architettura interpreta lo sviluppo sostenibile e coerente delle città. Ciò alla luce delle linee strategiche dettate da "Vision 2030", il programma con cui il Principe Salman bin Abdulaziz…

Understanding and managing process interaction in IS development projects

2012

Published version of an article from the book: Nordic Contributions in IS Research. Also available on SpringerLink:http://dx.doi.org/10.1007/978-3-642-32270-9_2 Software-based information systems must be developed and implemented as a part of business change. This is a major challenge, since business change and the development of software-based information systems usually are performed in separate processes. Thus, there is a need to understand and manage the relationship between these two kinds of processes. In this paper we draw on a longitudinal case study. We suggest a framework to analyze the case as interaction between software development processes and organizational change processes.…

Reducing the Human Effort in Text Line Segmentation for Historical Documents

2021

Labeling the layout in historical documents for preparing training data for machine learning techniques is an arduous task that requires great human effort. A draft of the layout can be obtained by using a document layout analysis (DLA) system that later can be corrected by the user with less effort than doing it from scratch. We research in this paper an iterative process in which the user only supervises and corrects the given draft for the pages automatically selected by the DLA system with the aim of reducing the required human effort. The results obtained show that similar DLA quality can be achieved by reducing the number of pages that the user has to annote and that the accumulated h…

Algorithms for rational discrete least squares approximation

1975

In this paper an algorithm for the computation of a locally optimal polefree solution to the discrete rational least squares problem under a mild regularity condition is presented. It is based on an adaptation of projection methods [8], [12], [13], [14], [18], [19] to the modified Gaus-Newton method [4], [10]. A special device makes possible the direct handling of the infinitely many linear constraints present in this problem.

On some flaws of university rankings: The example of the SCImago report

2012

International audience; Using France as our main example, we show there is a much scope for improving the SCImago ranking. We detect problems of nomenclature, double affiliation, aggregation and of bias toward large public-funded research organizations. The output per scholar is more important than the output per organization. The examples we cite suggest that only detailed knowledge of the situation can help in addressing the issue and take us beyond any automatic reading of the metadata.

Normalizing biproportional methods

2002

International audience; Biproportional methods are used to update matrices: the projection of a matrix Z to give it the column and row sums of another matrix is R Z S, where R and S are diagonal and secure the constraints of the problem (R and S have no signification at all because they are not identified). However, normalizing R or S generates important mathematical difficulties: it amounts to put constraints on Lagrange multipliers, non negativity (and so the existence of the solution) is not guaranteed at equilibrium or along the path to equilibrium.

フィンランドのネウボラの視察から見えたわが国の利用者支援事業の課題 －ケースの視察及び利用者インタビューから－ [Issues Related to Japan's User Support Project for Children and Childcare Support System Dis…

2016

The aim of this article is to introduce Neuvola, a childrearing support service in Finland, and to discuss issues related to Japanʼs User Support Project for Children and Childcare Support System. The authors visited and sat in on Neuvola sessions for three clients, and they conducted interviews with a client between October 4 and 8, 2015. Clients and Neuvola nurses were relaxed, and clients initiated the topics discussed during the visit. There was rapport between clients and Neuvola nurses, and clients seemed to be at ease in receiving the service. During the interviews, the client mentioned that she was able to talk about sensitive issues because the nurses would help the family to move …
