Towards Automated Classification of Firmware Images and Identification of Embedded Devices

2017

Part 4: Operating System and Firmware Security; International audience; Embedded systems, as opposed to traditional computers, bring an incredible diversity. The number of devices manufactured is constantly increasing and each has a dedicated software, commonly known as firmware. Full firmware images are often delivered as multiple releases, correcting bugs and vulnerabilities, or adding new features. Unfortunately, there is no centralized or standardized firmware distribution mechanism. It is therefore difficult to track which vendor or device a firmware package belongs to, or to identify which firmware version is used in deployed embedded devices. At the same time, discovering devices tha…

Comparison of the Richardson and BCS models of superconductivity based on calculations of ground state energies

2017

Suprajohtavuuden Richardsonin ja BCS mallien vertailu perustilojen laskettujen energioiden perusteella. Suprajohtavuus on edelleen aktiivinen tutkimuksen alue, koska sen tarjoamista mahdollisuuksista huolimatta sitä ei vielä ymmärretä kokonaisvaltaisesti. Tässä pro gradu -tutkielmassa käyn läpi perusteet kahdelle suprajohtavuuden mallille, Richardsonin ja BCS malleille. BCS teoria on ensimmäinen ja käytetyin mikroskooppinen suprajohtavuuden teoria. Richardsonin malli on harvemmin käytetty malli, josta saadaan redusoidun BCS Hamiltonin operaattorin tarkat ominaistilat. Lasken molempien mallien perustilojen energiat sekä redusoidulle että täydelle BCS Hamiltonin operaattorille. Sama lasketaan…

A modelling framework for social media monitoring

2013

This paper describes a hierarchical, three-level modelling framework for monitoring social media. Immediate social reality is modelled through the first level of the models. They represent various virtual communities at social media sites and adhere to the social world models of the sites, i.e., the "site ontologies". The second-level model is a temporal multirelational graph that captures the static and dynamic properties of the first-level models from the perspective of the monitoring site. The third-level model consists of a temporal relational database scheme that models the temporal multirelational graph within the database. The models are specified and instantiated at the monitoring s…

Consumer value of camera-based mobile interaction with the real world

2013

Camera-based mobile interaction with the real world allows consumers to connect digital information with the real-world environment, and furthermore, to interact with real-world objects and places. To explore and understand the types of consumer value in the context of such consumer-level applications, we applied the critical incident technique to reflect actual use experiences from 107 application users with a recognized consumer value framework by Holbrook. The findings of the study suggest that at the current state value is heavily based on utilitarian efficiency and excellence. Although the applications enable a diverse value, they have yet to fulfill their potential in providing hedoni…

Utilizing online serious games to facilitate distributed requirements elicitation

2015

Online serious games are used to facilitate distributed requirements elicitation.Interactive games enhance collaboration and communication between project members.Serious games raise individuals' confidence to engage in requirements elicitation.Using serious games can improve both quality and quantity of software requirements.Serious games specially enhance the performance of less-experienced stakeholders. Requirements elicitation is one of the most important and challenging activities in software development projects. A variety of challenges related to requirements elicitation are reported in the literature, of which the lack of proper communication and knowledge transfer between software …

Visualization in the integrated SimPhoNy multiscale simulation framework

2018

Abstract We describe three distinct approaches to visualization for multiscale materials modelling research. These have been developed with the framework of the SimPhoNy FP7 EU-project, and complement each other in their requirements and possibilities. All have been integrated via wrappers to one or more of the simulation approaches within the SimPhoNy project. In this manuscript we describe and contrast their features. Together they cover visualization needs from electronic to macroscopic scales and are suited to simulations made on personal computers, workstations or advanced High Performance parallel computers. Examples as well as recommendations for future calculations are presented.

"All Tito wants is a little bit of unity" : kuva Titon Jugoslaviasta The New York Timesissa vuosina 1969- 1971

2012

Irtauduttuaan Neuvostoliiton johtamasta Itä-Euroopan kommunistimaiden liittoumasta 1940- luvun lopulla Titon johtama Jugoslavia kehittyi kylmän sodan aikana omaa tietään kulkevaksi sosialistiseksi valtioksi, joka oli ulkopolitiikassaan sitoutumaton etsien samalla paikkaansa idän ja lännen välissä, jonka talousjärjestelmä perustui ns. työläisten itsehallintojärjestelmään ja jonka sisäpoliittista kehitystä sävyttivät toisaalta erilaiset pyrkimykset reformeihin sekä toisaalta kysymykset siitä, miten Jugoslavian eri osatasavaltojen keskinäinen suhde kehittyisi ja vaikuttaisi näin koko maan tulevaisuuteen. 1960–1970-lukujen vaihteessa maassa elettiin sisäpoliittisesti epävakaata kautta, johon li…
