AI for Resource Allocation and Resource Allocation for AI: a two-fold paradigm at the network edge

2022

5G-and-beyond and Internet of Things (IoT) technologies are pushing a shift from the classic cloud-centric view of the network to a new edge-centric vision. In such a perspective, the computation, communication and storage resources are moved closer to the user, to the benefit of network responsiveness/latency, and of an improved context-awareness, that is, the ability to tailor the network services to the live user's experience. However, these improvements do not come for free: edge networks are highly constrained, and do not match the resource abundance of their cloud counterparts. In such a perspective, the proper management of the few available resources is of crucial importance to impr…

Visual and optical performance with hybrid multifocal intraocular lenses

2010

During the past years, the wish to become independent of spectacles has been growing among cataract and presbyopic patients due to many factors, such as the increase in near visual demands, the aesthetic need for a spectacle-free image and ageing of refractive surgery patients, among others. This review assesses recently published studies that analyse visual and optical performance through different metrics of eyes implanted with multifocal intraocular lenses (IOLs), particularly hybrid IOL designs. The published evidence suggests that hybrid multifocal IOLs provide very good outcomes in a number of visual and optical performance parameters. Patients implanted with this type of IOL obtain a…

ANALYSE EMPIRIQUE DES ECARTS DE PREVISIONS DE BENEFICES DANS LES PROSPECTUS D'INTRODUCTION : LE CAS FRANCAIS

2002

International audience; Sur un échantillon de 151 introductions en bourse en France, nous analysons les biais et la rationalité des prévisions de bénéfices contenues dans les prospectus d'introduction. Nous proposons également un modèle explicatif des écarts de prévisions et vérifions si la performance boursière des actions est fonction des écarts de prévision.

Production Inventory and Enterprise System Implementation: An Ex-ante No-Cost Based Evaluation

2010

The objective of this paper is to present an Enterprise System (ES) ex-ante no-cost based three step evaluation technique, which enables a pre-emptive analysis of the effects of an ES implementation using a system of referenced non financial performance metrics. The innovativeness is in the use of a simulation model fully integrated with the evaluation procedure. Researchers can extend the presented technique to further modelling approaches and test it on different market sectors. The analysis provides practitioners with a measurement system that enables an analysis of the effects of a given ES implementation and can be further employed in financial evaluations.

Predicting lorawan behavior. How machine learning can help

2020

Large scale deployments of Internet of Things (IoT) networks are becoming reality. From a technology perspective, a lot of information related to device parameters, channel states, network and application data are stored in databases and can be used for an extensive analysis to improve the functionality of IoT systems in terms of network performance and user services. LoRaWAN (Long Range Wide Area Network) is one of the emerging IoT technologies, with a simple protocol based on LoRa modulation. In this work, we discuss how machine learning approaches can be used to improve network performance (and if and how they can help). To this aim, we describe a methodology to process LoRaWAN packets a…

Effect of ionization and the nature of the mobile phase in quantitative structure-retention relationship studies.

2005

Abstract The octanol–water distribution constant, commonly called partition coefficient, Po/w, is a parameter often retained as a measure of the hydrophobicity of a molecule. log Po/w, for a given molecule, can be conveniently evaluated constructing correlation lines between standard retention factor logarithms (log k) in reversed-phase liquid chromatography (RPLC) and standard log Po/w values. Many compounds of pharmaceutical interest can be quite hydrophobic and have, simultaneously, basic nitrogen atoms or acidic sulfur containing groups in their structure. This renders them ionizable. The hydrophobicity of the molecular drug form (Po/w value) is completely different from its ionic form …

Traductions, transformations, transmutations du Pygmalion de Rousseau dans les royaumes de Naples et de Sicile

2017

The Rousseau’s Melodrama, Pygmalion, first time staged in 1771 at Lyon, arrived in Naples in 1773 performed in French by a French theatrical company and with the music composed by Aspelmayr. At the same time in the kingdom of Naples, like in northern Italy and in Austria, the first Italian translations and the first attempt to change the original text in an Opera libretto put essential questions about the translation of theatrical texts and especially the change of a dramatic-musical form, a semiotic transmutation. In 1797, in Palermo, according to the historian Pitrè, was staged a Pigmalione or Pigmaglione translated perhaps by Sografi, transmuted in operatic form, put in music by Asioli o…

Is the French mobile phone cartel really a cartel?

2009

International audience; France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France's Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth, respectively) and for directly exchanging commercial information. While not contesting the legal decision, it is argued here that the economic reasoning is flawed. (1) As the CC made much of the firms' stable market shares, we have first followed this line of reasoning by considering that the market shares are quotas under uniform costs. Even if there is a general incentive to form a monopolistic cartel, BT was too small for it to be worth its while to join it; it i…
