Local Structure Studies of Ti for SrTi16O3 and SrTi18O3 by Advanced X-ray Absorption Spectroscopy Data Analysis
2015
Strontium titanate is a model quantum paraelectric in which in the region of dominating quantum statistics the ferroelectric instability is inhibited due to nearly complete compensation of the harmonic contribution into ferroelectric soft mode frequency by the zero-point motion contribution. The enhancement of atomic masses by the substitution of 18O for 16O decreases the zero-point atomic motion and low-T ferroelectricity in SrTi18O3 is realized. In this study we report on the local structure of Ti in SrTi16O3 and SrTi18O3 by Ti K-edge extended x-ray absorption fine structure measurements in temperature range 6 – 300 K.
Analysis and description of an open source janitor project
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad The objective of this study is to describe the inside and impact of the Linux Kernel Janitor Project. To describe and discuss how such janitor activity can be useful for others is also an objective. The Linux Kernel Janitor Project is a project defined to perform maintenance of the Linux kernel source, often taking on tasks that nobody else will be doing. The patches produced by the janitors have been analysed and some of the effects and properties of the work the project has carried out are described. Analysis show that janitor activity reduces the amount of code while still keeping the same functio…
Joukkoistamisen käyttö vaatimusmäärittelyssä : tapaustutkimus
2017
Tämän pro gradu -tutkielman lähtökohta oli tutkia, miten joukkoistamista voidaan käyttää vaatimusmäärittelyssä. Kirjallisuuskatsauksen lisäksi luotiin joukkoistetun vaatimusmäärittelyn malli sekä tehtiin tapaustutkimus KoiraNet jalostustietojärjestelmän MH-luonnekuvausta koskevaan dataan liittyvien käyttötarpeiden selvittämisestä ja joukkoistetusta vaatimusmäärittelystä. Joukkoistaminen tapahtui projektia varten luodussa Facebook-ryhmässä, johon saatiin avoimella kutsulla kaikkiaan 107 jäsentä. Tutkimuksen tuloksiin lukeutui paitsi kerätyt vaatimukset, myös joukon aktiivisuudesta tehdyt määrälliset havainnot. Joukkoistamalla kerättyjen vaatimusten laadun arvioimiseksi suoritettiin erilliset…
Systemic Management of Architectural Decisions in Enterprise Architecture Planning. Four Dimensions and Three Abstraction Levels
2006
This paper presents a process model for the management of architectural decisions in enterprise architecture planning. First, decisions are made at the enterprise level, with strategic business considerations on the enterprise information, systems and technology strategy and governance issues. The next step is to define the domains, to then go on with domain architecture decisions. At the systems level, the enterprise and domain architecture decisions are collected and converted into architecture descriptions accurate in precision, form and detail to be given as input to the information systems development process, following the architectural planning. The model is derived from previous wor…
Elements of Sustainability for Public Sector Software : Mosaic Enterprise Architecture, Macroservices, and Low-Code
2021
Public sector is a large consumer for software. In countries such as Finland, many of the systems are made to order by consultancy companies that participate in public tenders. These tenders initiated by the state, cities, and other public sector organizations. Furthermore, as public sector tasks are often decomposed to various actors, each and every one of them makes their purchase based on their own needs. In this paper, we argue that to maintain software sustainability in this context, there is a need for three key elements. Firstly, there is a need for an enterprise architecture where independent services from various vendors are can be easily deployed and integrated. Secondly, these se…
Introduction to software product lines : Engineering, service, and management minitrack
2013
Software has become the key asset for competitive products and services in all industries. Thus, competitiveness in software development, maintenance, and related services has become a concern for organizations. Competitiveness can be increased through (1) internal strategies such as the strategic creation and reuse of software assets and (2) external strategies such as outsourcing software development, maintenance, and/or services from third party service providers and acquiring off-the-shelf components from providers and open source communities. A viable third strategy is to enact both strategies in parallel. This minitrack focuses on the first and third strategy. The minitrack accepted f…
Development of Network Security Education
2021
Distance education has grown tremendously over the last decade. Internet technologies have enabled a large-scale dispensation of lectures, exercises, and training. Virtual Learning Management Systems (LMSs) offer a number of tools to realize distance education and distance learning. In this work, we present a virtual system architecture for training cyber security professionals with hands-on skills. The architecture is based on a VirtualBox virtualization environment. Guest machines are installed on an instance of VirtualBox. The installed environment offers a safe and isolated workbench for experiments. After installation and configuration of the environment, students perform a number of i…
Evaluating End-user Support : Validating the Use of Multiple Media in a CSCW Application
2006
Human-centred views on information systems are gaining more and more attention in IS community. The need to evaluate information systems from such a perspective is thus evident. In this paper, we exploit our earlier developed theoretical framework for evaluating end-user support in information systems, and demonstrate its usage in validating the use of multiple communication and collaboration media in a CSCW application. The evaluation is performed in terms of user perception in ISD process, users’ role in organizational information processing, and users’ behavioural nuances. Our study shows that a context specific theoretical framework is useful in validating the empirical results of syste…
Social welfare professionals willing to participate in client information system development - Results from a large cross-sectional survey.
2021
Human-centered design methods should be implemented throughout the client information system (CIS) development process to understand social welfare professionals’ needs, tasks, and contexts of use. The aim of this study was to examine Finnish social welfare professionals’ experiences of participating in CIS development. A national cross-sectional web-based survey on the CIS experiences of social welfare professionals (1145 respondents) was conducted in Finland in spring 2019. This study focused on statements concerning the experiences of end users with CIS development and participation. The results are reported by professional and age groups. Half (50%) of the 1145 respondents had participa…
Towards Practical Cybersecurity Mapping of STRIDE and CWE — a Multi-perspective Approach
2021
Software vulnerabilities are identified during their whole life-cycle; some vulnerabilities may be caused by flaws on the design while other appear due to advances on the technologies around the systems. Frameworks such as OWASP are well- known and are used for testing a systems security before or after implementation, and such testing is carried out against the existing system. Threat modeling however focuses on the early stages of the system design when it is feasible and easy to fix security-related flaws and prevent possible damage caused by them. For example, STRIDE is one very popular threat modeling framework. A STRIDE threat modelling specialist deals with abstract categorizations o…
