Itô-Stratonovitch Formula for the Wave Equation on a Torus
2010
We give an Ito-Stratonovitch formula for the wave equation on a torus, where we have no stochastic process associated to this partial differential equation. This gives a generalization of the classical Ito-Stratonovitch equation for diffusion in semi-group theory established by ourself in [18], [20].

Document de référence d’une entreprise française : types de procès de la partie environnementale
2012
Tässä tutkimuksessa tarkasteltiin erään yrityksen vuosikertomuksen tekstin rakennetta. Tutkimuksen teoreettisena pohjana toimi M. A. K Hallidayn kehittämä systeemi- eli systeemis-funktionaalinen kielioppi, jonka määrittelemät eri prosessityypit toimivat lähemmän tarkastelun kohteena. Tutkimuksessa selvitettiin, mitä prosessityyppejä tekstistä on löydettävissä ja kuinka usein nämä esiintyvät aineistossa. Saatuja tuloksia verrattiin erääseen aikaisemmin ilmestyneeseen samankaltaiseen tutkimukseen. Aineistona tutkimuksessa käytettiin tekstiotteita ranskalaisen Arkema-nimisen yrityksen vuoden 2010 vuosikertomuksesta, tarkemmin sen ympäristöä käsittelevästä osiosta.
Aurinkosähkön tekninen potentiaali Jyväskylässä
2014
Tutkielman tavoitteena on selvittää Jyväskylän asuinrakennusten aurinkosähköistä potentiaalia simuloimalla katolle asennettavan aurinkosähköjärjestelmän tuottoja ja vertaamalla niitä rakennuksen sähkönkulutukseen. Tarkastelu tehtiin tätä tarkoitusta varten suunnitellun MATLAB-ohjelman avulla. Laskennan pohjana käytettiin Jyväskylän yliopiston kemian laitoksen sääasemalta saatuja säteily-, lämpötila- ja tuulennopeusaineistoja vuosilta 2010 ja 2011. Tutkimuskohteina käytettiin viittä kerrostaloa, jotka sijaitsevat alle 1,5 kilometrin etäisyydellä sääasemasta. Tasakatolle sijoitettavat aurinkosähköpaneelit suunnattiin etelään 47 asteen kallistuskulmassa. Harjakatoille paneelit sijoitettiin lap…

Synchronous R-NSGA-II: An Extended Preference-Based Evolutionary Algorithm for Multi-Objective Optimization
2015
Classical evolutionary multi-objective optimization algorithms aim at finding an approx- imation of the entire set of Pareto optimal solutions. By considering the preferences of a decision maker within evolutionary multi-objective optimization algorithms, it is possible to focus the search only on those parts of the Pareto front that satisfy his/her preferences. In this paper, an extended preference-based evolutionary algorithm has been proposed for solving multi-objective optimiza- tion problems. Here, concepts from an interactive synchronous NIMBUS method are borrowed and combined with the R-NSGA-II algorithm. The proposed synchronous R-NSGA-II algorithm uses preference information provid…
Context–content systems of random variables : The Contextuality-by-Default theory
2016
Abstract This paper provides a systematic yet accessible presentation of the Contextuality-by-Default theory. The consideration is confined to finite systems of categorical random variables, which allows us to focus on the basics of the theory without using full-scale measure-theoretic language. Contextuality-by-Default is a theory of random variables identified by their contents and their contexts, so that two variables have a joint distribution if and only if they share a context. Intuitively, the content of a random variable is the entity the random variable measures or responds to, while the context is formed by the conditions under which these measurements or responses are obtained.

Biased graph walks for RDF graph embeddings
2017
Knowledge Graphs have been recognized as a valuable source for background information in many data mining, information retrieval, natural language processing, and knowledge extraction tasks. However, obtaining a suitable feature vector representation from RDF graphs is a challenging task. In this paper, we extend the RDF2Vec approach, which leverages language modeling techniques for unsupervised feature extraction from sequences of entities. We generate sequences by exploiting local information from graph substructures, harvested by graph walks, and learn latent numerical representations of entities in RDF graphs. We extend the way we compute feature vector representations by comparing twel…
Simplicity and the art of something more: A cognitive-semiotic approach to simplicity and complexity in human-technology interaction and design exper…
2018
In human–technology interaction, the balance between simplicity and complexity has been much discussed. Emphasis is placed on the value of simplicity when designing for usability. Often simplicity is interpreted as reductionism, which compromises both the affective nature of the design and usability itself. This paper takes a cognitive–semiotic approach toward understanding the dynamics between the utilitarian benefits of simplicity in design and the art of something more: considerate complexity. The cognitive–semiotic approach to human–technology design experience is a vehicle for explaining the relationship between simplicity and complexity, and this relationship’s multisensory character …
Essence : Reference Architecture for Software Engineering - Representing Essence in Archimate Notation
2018
Essence is a standard for working with methods in software engineering. As such, it can be seen as the reference architecture for software engineering. The Essence consists of the Kernel, and a notation called the Language. This representation is not widely known and likely hinders the adoption of the Essence. This paper represents the work-in-progress of representing the Essence using ArchiMate, the de facto notation for enterprise architecture. Our purpose is to help organisations to adopt Essence by representing it in the language already understood by different stakeholders. peerReviewed
