Kiinan suorittaman kybervakoilun aiheuttamat pitkäaikaiset haitat KIBS-yrityksille

2015

Tämä kandidaatintutkielma käsittelee Kiinan suorittaman kybervakoilun aihe- uttamia pitkäaikaisia haittoja KIBS-yrityksille. Tutkielma toteutettiin kirjalli- suuskatsauksena teorialähtöisesti. Tutkielma selvittää, millaisia haittoja Kiinan suorittama kybervakoilu aiheuttaa KIBS-yrityksille, sekä lisäksi sen, kuinka va- kavia nämä KIBS-yrityksille koituneet haitat ovat. Aihetta on tärkeä tutkia, sillä Kiinan suorittamasta kybervakoilusta on saatu todisteita. Lisäksi kybervakoilusta koituvien haittojen on arvioitu olevan nousussa. Aihetta ei ole aiemmin tutkittu riittävästi, sillä sitä on hankala tutkia, koska yritykset eivät monesti tahdo tuoda julkisuuteen joutuneensa k…

Modelling landslides in unsaturated slopes subjected to rainfall infiltration using material point method

2016

This paper presents a dynamic fully coupled formulation for saturated and unsaturated soils that undergo large deformations based on material point method. Governing equations are applied to porous material while considering it as a continuum in which the pores of the solid skeleton are filled with water and air. The accuracy of the developed method is tested with available experimental and numerical results. The developed method has been applied to investigate the failure and post-failure behaviour of rapid landslides in unsaturated slopes subjected to rainfall infiltration using two different bedrock geometries that lie below the top soil. The models show different failure and post-failur…

Jak pozostać sobą w obcym języku? Strategie konwersji językowej pisarzy pochodzenia słowiańskiego

2017

Ihe article is dcvoted to writers who after emigrating decided to change the language in which they wrote their books from their native language to the language of the country which became their second home. The strategies which are described in the article are determined by the personal experiences of the writers, for whom the choice of a second language in which their works were to be written became an opportunity to express various attitudes. Piotr Rawicz, a Jew of Polish origin, treated his literary debut - the novel Le sang du ciel, written in French - as an autobiography, which was expressed not in a direct manner but in a manncr based on intermediation of both the complex narrative d…

L’éducation au plurilinguisme dès l’enfance : des réalités aux moyens d’agir (Maghreb, particulièrement l’Algérie)

2017

Ce que nous apprend la psycholinguistique, en particulier les chercheurs qui œuvrent sur plusieurs langues et dans une perspective interculturelle, c’est le caractère essentiel des premières acquisitions : non seulement le langage à travers la langue 1, mais avec langage par la langue 1, les fondamentaux de la pensée, concepts-cadres et relations.Nous constatons que l’école exerce ensuite un passage brutal en langue de scolarisation, et refuse la langue1 ; pourtant celle-ci pourrait jouer l’indispensable rôle de transition (1re année primaire, par ex.) afin de relier les premières acquisitions socio-cognitives et langagières avec les apprentissages scolaires. What psycholinguistics teaches …

Rail and Joint Bar (Fish Plate) NDE Advances in North America

2010

Improvement and development of rail track nondestructive inspection (NDI) technologies to reduce in-service failures of rail and joint bars (fish plates) in a continuous effort to make rail transport safer is a primary focus for the railroad industry. Researchers at The Transportation Technology Center, Inc., working under the direction of the Association of American Railroads and its Strategic Research Initiative Program, have worked with companies worldwide to develop novel NDI approaches for dynamic inspection of rail and joint bars. In the area of rail inspection an ultrasonic rail (U-Rail) system for noncontact rail flaw inspection has been developed. This system combines high energy l…

Sulle orme del consumatore affinity analysis e knowledge visualization per il processo decisionale

2016

L’articolo analizza i reali comportamenti di acquisto dell’acquirente all’interno del punto vendita e individua i pattern latenti più significativi attraverso un’analisi di affinità di 128.364 scontrini estratti da un dataset di 715.662 transazioni effettuate in un anno. Lo studio individua le strutture associative più ricorrenti relativamente alla singola merceologia. Attraverso la tecnica della Market Basket Analysis è stato possibile individuare le categorie merceologiche che creano “poli d’attrazione” sul punto vendita stimolando acquisti di altre categorie. In particolar modo, applicando le regole associative sul punto vendita è stato possibile identificare le “aree calde” e le “aree f…

Sharing on web 3D models of ancient theatres. A methodological workflow

2016

Abstract. In the last few years, the need to share on the Web the knowledge of Cultural Heritage (CH) through navigable 3D models has increased. This need requires the availability of Web-based virtual reality systems and 3D WEBGIS. In order to make the information available to all stakeholders, these instruments should be powerful and at the same time very user-friendly. However, research and experiments carried out so far show that a standardized methodology doesn’t exist. All this is due both to complexity and dimensions of geometric models to be published, on the one hand, and to excessive costs of hardware and software tools, on the other. In light of this background, the paper describ…

Plasmonic Stripes in Aqueous Environment Co-Integrated With Si3N4 Photonics

2018

We demonstrate the design, fabrication, and the experimental characterization of gold-based plasmonic stripes butt-coupled with low-pressure-chemical-vapor-deposition (LPCVD)-based Si3N4 waveguides for the excitation of surface-plasmon-polariton (SPP) modes in aqueous environment. Plasmonic gold stripes, in aqueous environment, with cross-sectional dimensions of 100 nm × 7 μm were interfaced with 360 nm × 800 nm Si3N4 waveguides cladded with low-temperature-oxide, exploiting linear photonic tapers with appropriate vertical (VO) and longitudinal (LO) offsets between the plasmonic and photonic waveguide facets. An interface insertion loss of 2.3 ± 0.3 dB and a plas…

RAPID PROTOTYPING FOR THE EXTENSION OF THE ACCESSIBILITY TO CULTURAL HERITAGE FOR BLIND PEOPLE

2019

Abstract. The extension of accessibility of CH to disabled people is a current topic of great importance. Today, there exist a lot of ongoing projects aimed at the extension of accessibility using the most recent and low cost technologies to improve accessibility to CH. One of the technologies, today available that can help to improve accessibility to CH, is certainly rapid prototyping. The main goal of the research here illustrated is the application of rapid prototyping for the extension of accessibility of Cultural Heritage (CH) to blind and visually impaired people. This document reports an experiment that compared the effectiveness of different 3D models for the introduction of blind a…
