Modeling and Backstepping Control of the Electronic Throttle System
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/871674 Open access Electronic throttle is widely used in modern automotive engines. An electronic throttle system regulates the throttle plate angle by using a DC servo motor to adjust the inlet airflow rate of an internal combustion engine. Its application leads to improvements in vehicle drivability, fuel economy, and emissions. In this paper, by taking into account the dynamical behavior of the electronic throttle, the mechanism model is first built, and then the mechanism model is transformed into the state-space model. Based on the s…
Production and Efficiency in 21 Industrialized Countries from 1966 to 2007 to Analyse the Italy’s Decline: Application of a Stochastic Frontier Model…
2008
This paper uses a stochastic frontier production model to estimate the technical efficiency of 21 nations among the more industrialized countries in the world for the wide period from 1966 to 2007. A Cobb-Douglas with labour and capital as inputs, GDP as output and efficiency with exponential distribution appears to work good from a statistical point of view. This model is used to estimate in a bayesian approach the efficiency score of these 21 countries. The bayesian way, applied via Gibbs sampling, is here useful to avoid problems about the small number of observations. So, each efficiency score is obtained as mean of 10,000 draws. The results underline a general and progressive efficienc…
Female Technology Education Teachers’ Experiences of Finnish Craft Education
2016
In order to introduce a more equitable gender balance in education and consequently in the labour market, it is highly relevant to continue to expand our knowledge of technology education and to give attention to gender related issues. The ultimate purpose of this study was to contribute to efforts to get more women to study technology and pursue technological careers by investigating their experiences. To approach this, the aim was to offer an overview of the gendered processes that girls and women may experience when studying and working in the area of technical craft and technology education. The study was carried out using semi-structured theme interviews, and the data were collected fr…
THE RELATIONSHIP BETWEEN WOMEN´S ARTISTIC GYMNASTICS TECHNICAL SKILL, PHYSICAL PERFORMANCE TEST RESULTS AND SUCCESS IN COMPETITIONS IN FINLAND
2019
The aim of this study was to find out the potential of the Minoritest to identify the most likely talented gymnasts to join the national team pre-training group in Finland. The study examined the relationships between gymnasts´ (N=215, age 10–13) Minoritest results (2006–2010) and success in competitions after the Minoritests until the end of 2016. The competition results were also compared between the gymnasts who had participated in the test and a random number (N=180) of gymnasts who had not. According to this study, the majority (92%) of the best gymnasts in competitions had participated in the Minoritest. 39% of the best in competitions were among the top 10 in the Minoritest. The test…
Seeking Technical Debt in Critical Software Development Projects : An Exploratory Field Study
2016
In recent years, the metaphor of technical debt has received considerable attention, especially from the agile community. Still, despite the fact that agile practices are increasingly used in critical domains, to the best of our knowledge, there are no studies investigating the occurrence of technical debt in critical software development projects. The results of an exploratory field study conducted across several projects reveal that a variety of business and environmental factors cause the occurrence of technical debt in critical domains. Using Grounded Theory method, these factors are categorized as ambiguity of requirement, diversity of projects, inadequate knowledge management, and res…
Hydro-mechanical modelling of MX-80 bentonite: one dimensional study
2016
As a first step towards modelling the coupled Thermo-Hydro-Mechanical-Chemical (THMC) behaviour of bentonite, the Barcelona Basic Model (BBM) has been implemented into Numerrin finite element code. This model has been fully coupled with the single phase flow equation for unsaturated soils which models liquid water transport. Suction obtained from solving the flow equation is used as an input for the BBM model and the volumetric deformations from the mechanical analysis are used to update the pore water pressure field. As an alternative, BBM is used alongside the Kröhn’s model which assumes that bentonite re-saturation is mainly driven by water vapour diffusion. The paper simulates one dimen…
Looking for Peace of Mind? Manage your (Technical) Debt : An Exploratory Field Study
2017
Background: In the last two decades Technical Debt (TD) has received a considerable amount of attention from software engineering research and practice. Recently, a small group of studies suggests that, in addition to its technical and economic consequences, TD can affect developers’ psychological states and morale. However, until now there has been a lack of empirical research clarifying such influences. Aims: In this study, we aim at taking the first step in filling this gap by investigating the potential impacts of TD and its management on developers’ morale. Method: Drawing from previous literature on morale, we decided to explore the influence of TD and its management on three dimensio…
Visibility without voice: Media witnessing irregular migrants in BBC online news journalism
2016
In the analysis of journalistic representation of irregular migration to Europe, rather little attention is given to the variation of modes and genres of journalism. Most studies focus on text in ‘old media’ and the news genre. This article analyses affordances of different modalities and genres of online journalism in framing irregular migrants. Media framing in BBC online news coverage of a mediatised conflict in Spain, defined as a ‘migration crisis’, is analysed with multimodal social semiotics. While mediation makes global audiences witness tragedies at Europe's borders and online journalism affords more voice and deliberation for migrant sources, the frames of threat and victim domina…
Humanisierung des technischen Fortschritts. Ein Projekt von Papst Franziskus
2020
Theology of technique, in addition to the philosophy of technique, opens up a new research perspective on technique that defines everything or almost everything in the reality that surrounds us. The aim of these considerations my research is to seek a new idea of technological progress that will allow building of an integral vision of reality. The teaching of Pope Francis, especially in the Encyclical Laudato si’ (2015), forms the basis for the selected topic. The structure of the considerations refers to the principles of the social doctrine of the so-called three steps: look, judge, act. Therefore, the text presents firstly the features of technical progress (1), then its evaluation (2), …
Zwischen Rom und Silicon Valley. Papst Franziskus angesichts des technischen Fortschritts
2019
Co Rzym ma wspólnego z Doliną Krzemową? Innymi słowy, co Kościół ma współcześnie wspólnego z nauką i technologią? Jak Kościół odnosi się do problematyki postępu naukowo-technicznego, którego symbolem jest Dolina Krzemowa? Celem podjętych rozważań jest poszukiwanie nowej koncepcji postępu technicznego, uwzględniającej całościową wizję rzeczywistości. Nauczanie papieża Franciszka, zwłaszcza z Encykliki Laudato si’ (2015), stanowi podstawę realizacji wybranego tematu. Struktura rozważań nawiązuje do zasad nauki społecznej tzw. trzech kroków: zbadać, ocenić, działać. Dlatego w trakcie rozważań są prezentowane najpierw cechy postępu technicznego (1), dokonana jego ocena (2), a następnie elementy…
