Behaviour-driven development mobiiliohjelmistojen kehityksen tukena
2014
Lähivuosien aikana älypuhelinten yleistyminen on avannut mahdol- lisuuksia aivan uusille ohjelmistomarkkinoille. Samaan aikaan mobiilisovellusten yleistymisen kanssa myös ohjelmistokehityksen menetelmät ovat muuttuneet, ja vanhojen prosessien tilalle on tullut uusia iteratiivisia ketteriä menetelmiä. Tässä tutkielmassa selvitetään mahdollisuuksia hyödyntää käyttäytymislähtöisen ohjelmistokehityksen menetelmiä mobiilisovelluksia kehitettäessä. Since smartphone have become more and more common in recent years, it has opened completely new markets for software developers. At the same time, the software development processes have been evolving from old sequential processes to new agile and iter…
Anchoring Belonging Through Material Practices in Participatory Arts-Based Research
2020
How do people understand belonging and what kinds of stances toward belonging do they take? What kind of knowledge or ways of knowing (EISNER, 2008) does artistic practice yield about belonging? We ask these questions in this article, which is based on the research project Crossing Borders, in which we used participatory arts-based methods to study belonging. We invited participants to explore the notion of belonging in three parallel workshops drawing on different art forms, film, writing and visual arts. The goal of the workshops was for each participant to produce an artwork that deals with belonging. In the article, we identify four stances that the participants expressed toward the con…
Lisämateriaali julkaisuun: Genetic colour variation visible for predators and conspecifics is concealed from humans in a polymorphic moth
2022
The definition of colour polymorphism is intuitive: genetic variants express discretely-coloured phenotypes. This classification is however elusive as humans form subjective categories or ignore differences that cannot be seen by human eyes. We demonstrate an example of a ‘cryptic morph’ in a polymorphic wood tiger moth (Arctia plantaginis), a phenomenon that may be common among well-studied species. We used pedigree data from nearly 20000 individuals to infer the inheritance of hindwing colouration. The evidence supports a single Mendelian locus with two alleles in males: WW and Wy produce the white and yy the yellow hindwing colour. The inheritance could not be resolved in females as thei…

Attractor as a convex combination of a set of attractors
2021
This paper presents an effective approach to constructing numerical attractors of a general class of continuous homogenous dynamical systems: decomposing an attractor as a convex combination of a set of other existing attractors. For this purpose, the convergent Parameter Switching (PS) numerical method is used to integrate the underlying dynamical system. The method is built on a convergent fixed step-size numerical method for ODEs. The paper shows that the PS algorithm, incorporating two binary operations, can be used to approximate any numerical attractor via a convex combination of some existing attractors. Several examples are presented to show the effectiveness of the proposed method.…
Aerobisen ja anaerobisen kynnyksen määrittäminen laskennallisesti juoksumattotestidatasta
2017
Kunto- ja urheilutestauksessa halutaan usein selvittää henkilön aerobinen ja anaerobinen kynnys. Kynnykset voidaan jakaa määrityksessä käytettyjen muuttujien mukaan ventilaatio- ja laktaattikynnyksiin. Kynnykset ilmiönä ovat kiistanalaisia ja haasteellisia. Tässä tutkimuksessa tarkasteltiin kirjallisuudesta löytyviä aerobisen ja anaerobisen kynnyksen määritysmenetelmiä ja niiden soveltuvuutta suomalaiseen kuntotestausprotokollaan. Tutkimuksessa testattiin 12 kynnysmääritysmenetelmää, joista yksi oli kirjallisuudesta löytynyt, kahdeksan oli löytyneistä jatkokehitettyjä ja kolme uusia menetelmiä. Parhaat menetelmät saivat parempia tuloksia kuin kirjallisuudesta löytyneet tulokset. Determining…
Discrete exterior calculus for photonic crystal waveguides
2022
The discrete exterior calculus (DEC) is very promising, though not yet widely used, discretization method for photonic crystal (PC) waveguides. It can be seen as a generalization of the finite difference time domain (FDTD) method. The DEC enables efficient time evolution by construction and fits well for nonhomogeneous computational domains and obstacles of curved surfaces. These properties are typically present in applications of PC waveguides that are constructed as periodic structures of inhomogeneities in a computational domain. We present a two-dimensional DEC discretization for PC waveguides and demonstrate it with a selection of numerical experiments typical in the application area. …
Interspace for empathy : engaging with work-related uncertainty through artistic intervention in management education
2022
How can artistic intervention facilitate empathic engagement with work-related uncertainty in postgraduate management education? To examine this, we theorize artistic intervention as creating an interspace of temporarily suspended organizational norms through which empathy as relational knowing can emerge between participants. Drawing on an ethnographic study entitled Becoming in Academia, a nine-month artistic intervention conducted by a group of doctoral students in a Nordic business school (NBS), this paper highlights how an interspace for empathic engagement with work-related uncertainty was created by the participants through three intervention activities: aligning oneself to the other…
