Protected Alvar Aalto building awarded for accessibility after renovation(Aalto University, 2016) Raike, Antti; Ahlava, Antti; Tuomi, Teemu; Skyttä, Pauliina; Verma, Ira; Arkkitehtuurin laitos; Department of Architecture; Kampuspalvelut; Campus Services; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and Architecture; Palvelut; ServicesThe main building of the former Helsinki University of Technology (TKK) designed by Alvar Aalto is part of the cultural heritage in Finland. The building underwent a major renovation in 2011–2015 and has now become an awarded Undergraduate Centre for the modern interdisciplinary education of Aalto University. This paper presents how the architectural masterpiece from the 1960’s was renovated and updated into a modern and accessible university building. Particular attention was paid for entering the building by wheelchairs, prams and pushchairs. The successful renovation was awarded in 2015 by the ‘Esteetön Suomi -palkinto’ (Accessible Finland Award), given every two years as a mark of recognition to activities or locations implementing the principles of accessibility and universal design for all on a broad scale and in a nationally significant way.Item Aaltovaikutus(Aalto University, 2019) Allinson, Matthew (kirjoittaja/toimittaja); Flowers, Andrew (kirjoittaja/toimittaja); Haikarainen, Paula (kirjoittaja/toimittaja); Hopiavaara, Riikka (kirjoittaja/toimittaja); Hölttä, Minna (kirjoittaja/toimittaja); Jurva, Katrina (kirjoittaja/toimittaja); Norjamäki, Niina (kirjoittaja/toimittaja); Ollikainen, Terhi (kirjoittaja/toimittaja); Rosin, Susanna (kirjoittaja/toimittaja); Seppälä, Helena (kirjoittaja/toimittaja); Särkisilta-Lundberg, Riitta (kirjoittaja/toimittaja); Tolonen, Annamari (kirjoittaja/toimittaja)Item Academic writing and dialogue: Reflections on the work of Janne Tienari(Aalto University, 2016) Meriläinen, Susan (editor); Vaara, Eero (editor); Johtamisen laitos; Department of Management Studies; Kauppakorkeakoulu; School of BusinessItem Active control of radial rotor vibrations in electric machines : identification, modeling and control design(Helsinki University of Technology, 2008) Orivuori, Juha; Laiho, Antti; Sinervo, Anssi; Department of Automation and Systems Technology; Automaatio- ja systeemitekniikan laitos; Faculty of Electronics, Communications and Automation; Elektroniikan, tietoliikenteen ja automaation tiedekuntaThis paper presents results related to modeling, identification, control design and simulation of an electric motor equipped with a new force actuator. The model consists of several partial models, thus separating certain physical phenomena into independent processes. The inputs and outputs of the models to be identified are strongly correlated. This makes the identification process significantly more complicated. Three different control algorithms are designed for the process. The performance of the control algorithms are tested against finite element models in extensive simulations. The paper concludes in description of preliminary test results with an actual test machine.Item Analysis and design of a position observer with resistance adaptation for synchronous reluctance motor drives(Institute of Electrical & Electronics Engineers (IEEE), 2011) Tuovinen, Toni; Hinkkanen, Marko; Luomi, Jorma; Sähkötekniikan ja automaation laitos; Department of Electrical Engineering and Automation; Electric Drives; Sähkötekniikan korkeakoulu; School of Electrical EngineeringA back-EMF-based reduced-order position observer with stator-resistance adaptation is analyzed for motion-sensorless synchronous reluctance motor drives. Analytical equations for steady-state estimation errors and stability conditions are derived (with and without resistance adaptation), taking into account errors in the parameter estimates. The effect of the observer gain on the noise reduction is studied by means of eigenvector analysis. A robust gain selection is proposed, which maximizes the allowed uncertainties in the parameter estimates. The proposed observer design is experimentally evaluated using a 6.7-kW synchronous reluctance motor drive; stable operation is demonstrated at low speeds under various parameter errors.Item Analysis and design of a position observer with stator-resistance adaptation for PMSM drives(Institute of Electrical & Electronics Engineers (IEEE), 2010) Hinkkanen, Marko; Tuovinen, Toni; Harnefors, Lennart; Luomi, Jorma; Sähkötekniikan ja automaation laitos; Department of Electrical Engineering and Automation; Electric Drives; Sähkötekniikan korkeakoulu; School of Electrical EngineeringThis paper deals with reduced-order observers with stator-resistance adaptation for motion-sensorless permanent-magnet synchronous motor drives. An analytical solution for the stabilizing observer gain and stability conditions for the stator-resistance adaptation are derived. The proposed observer design is experimentally tested using a 2.2-kW motor drive; stable operation at very low speeds under different loading conditions is demonstrated.Item Analysis of Different Models of Iron Precipitation in Multicrystalline Silicon(IEEE, 2014) Morishige, Ashley; Laine, Hannu; Schön, Jonas; Hofstetter, Jasmin; Haarahiltunen, Antti; Schubert, Martin; Savin, Hele; Buonassisi, Tonio; Mikro- ja nanotekniikan laitos; Department of Micro and Nanosciences; Sähkötekniikan korkeakoulu; School of Electrical EngineeringSimulation of solar cell processing enables inexpensive and rapid process optimization. Over the last twenty years, several models describing the distribution and behavior of iron point defects and iron-silicide precipitates have been developed and incorporated into process simulations. The goal of this work is to elucidate what physics are needed to accurately describe industry-relevant as-grown impurity and defect distributions and processing conditions by simulating different material-processing combinations with each model. This rigorous comparison helps scientists and engineers choose the appropriate level of model complexity, and consequently simulation run time, based on material characteristics and processing conditions.Item ARCH 14 - International Conference on Research on Health Care Architecture - November 19-21, 2014, Espoo, Finland - Conference Proceedings(Aalto University, 2015) Verma, Ira (ed.); Nenonen, Laura (ed.); Sanaksenaho, Pirjo; Fröst, Peter; Björgvinsson, Erling; Sandin, Gunnar; Ståhlberg-Aalto, Freja; Nord, Catharina; Yan, Shuang; Taegen, Jonna; Antinaho, Tuula; Kivinen, Tuula; Yli-Karhu, Tiina; Andersson, Morgan; Aalto, Leena; Nenonen, Suvi; Lindahl, Göran; Yläoutinen, Jyrki; Peltoniemi, Sanna; Andersson, Jonas E.; Rönn, Magnus; Gromark, Sten; Malmqvist, Inga; Nylander, Ola; Wijk, Helle; Elf, Marie; Thörn, Catharina; Verma, Ira; Lassfolk, Christina; Linnavuo, Matti; Talvitie, Sanna; Hietanen, Marja; Sepponen, Raimo; Paju, Vesa S.; Ketola, Eeva; Kariniemi-Örmälä, Kristiina; Halonen, Juha; Werning, Rashmi; Kuutti, Jussi; Paukkunen, Mikko; Eskelinen, Pekka; Nordin, Susanna; MacKee, Kevin; Kekäläinen, Reijo; Sepponen, Raimo E.; Arkkitehtuurin laitos; Department of Architecture; Sotera; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and ArchitectureHealthcare Architecture has grown rapidly in recent years. However, there are still many questions remaining. The commission, therefore, is to share the existing research knowledge and latest results and to carry out research projects focusing more specifically on the health care situation in a variety of contexts. The ARCH14 conference was the third conference in the series of ARCH conferences on Research on Health Care Architecture initiated by Chalmers University. It was realized in collaboration with the Nordic Research Network for Healthcare Architecture .It was a joint event between Aalto University, Finnish Institute of Occupational Health (FIOH) and National Institute of Health and Welfare (THL International).The conference gathered together more than 70 researchers and practitioners from across disciplines and countries to discuss the current themes.Item Architecture as human interface 2012 : the 4th symposium of architectural research in Finland - the 4th international conference on architectural competitions(Aalto University, 2014) Di Marino, Mina; Teräväinen, Helena (eds.); Arkkitehtuurin laitos; Department of Architecture; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and ArchitectureItem Around the world in 36 hours - Understanding the dynamics of the global product design relay marathon(European Society for Engineering Education, 2017) Tuulos, Tiina; Kauppinen, Tomi; Ivorra Penafort, L. R.; Riveros Ospina, D. I.; Design Factory; Design Factory; Factoryt; FactoriesIn this system paper we will present a learning experiment - a unique three-day global product design relay marathon organized by the Design Factory Global Network (DFGN). The experiment called Rat Relay simulates a real-world situation in product development where very often a person or team is only working on a project for a limited time and not from beginning to end, individuals work in multidisciplinary and multicultural teams around complex problems, and everything is done with a fast pace. Rat Relay is a learning experiment developed by the Design Factory Global Network, a network of innovation hubs in universities and research organizations in five continents of the world aiming to contribute to transformation of learning and research through a passion-based culture of interdisciplinary collaboration and effective problem solving.Item Art as we don't know it(Aalto University School of Arts, Design and Architecture, 2020) Berger, Erich (editor); Mäki-Reinikka, Kasperi (editor); O'Reilly, Kira (editor); Sederholm, Helena (editor)2018 marked the 10th anniversary of the Bioart Society and created the impetus for the publication of Art as We Don’t Know It. For this publication, the Bioart Society joined forces with the School of Arts, Design and Architecture of the Aalto University. The close history and ongoing collaborative relationship between the Bioart Society and Biofilia – Base for Biological Arts in the Aalto University lead to this mutual effort to celebrate together a diverse and nurturing environment to foster artistic practices on the intersection of art, science and society. Rather than stage a retrospective, we decided to invite writings that look forward and invite speculations about the potential directions of bioarts. The contributions range from peer-reviewed articles to personal accounts and inter-views, interspersed with artistic contributions and Bioart Society projects. The selection offers a purview of the rich variety, both in content and form, of the work currently being made within the field of bioart. The works and articles clearly trouble the porous and provisional definitions of what might be understood as bioart, and indeed definitions of bioart have been usefully and generativity critiqued since the inception of the term. Whilst far from being definitive, we consider the contributions of the book to be tantalising and valuable indicators of trends, visions and impulses. We also invite into the reading of this publication a consideration of potential obsolescences knowing that some of today’s writing will become archaic over time as technologies driven by contemporary excitement and hype are discarded. In so doing we also acknowledge and ponder upon our situatedness and the partialness of our purview in how we begin and find points of departure from which to anticipate the unanticipated. Whilst declining the view of retrospection this book does present art and research that has grown and flourished within the wider network of both the Bioart Society and Biofilia during the previous decade. The book is structured into four thematic sections Life As We Don’t Know It, Convergences, Learnings/Unlearnings, Redraw and Refigure and rounded off with a glossary.Item Art of Research 2023(Aalto University, 2023) Laakso, Harri; Pantouvaki, Sofia; Valle Noronha, Julia; Krokfors, Karin; Helke, Susanna; Falin, Priska; Arkkitehtuurin laitos; Department of Architecture; Elokuvataiteen ja lavastustaiteen laitos; Department of Film, Television and Scenography; Muotoilun laitos; Department of Design; Taiteen ja median laitos; Department of Art and Media; Taiteiden ja suunnittelun korkeakoulu; School of Arts, Design and ArchitectureItem Assistive tool for collaborative learning of conceptual structures(Springer Berlin Heidelberg, 2009) Lahti, Lauri; Tietotekniikan laitos; Department of Computer Science and Engineering; Perustieteiden korkeakoulu; School of ScienceThere is a demand for computational methods assisting learners to generate relevantassociations for current context. Many concepts in natural language have ambiguous meaningsimplying alternative ways to define associations for them. It is crucial to develop collaborativemethods that support free experiments with promising conceptual structures in learning.Methods for evaluating these structures in respect to the person’s needs are also required. Wepropose a new collaborative ideation scheme and based on that we have implemented anassistive tool for learning conceptual structures in a collaborative Web environment.Item Augmented Reality in Forest Machine Cabin(Elsevier B.V., 2017) Palonen, Tuomo; Hyyti, Heikki; Visala, Arto; Sähkötekniikan ja automaation laitos; Department of Electrical Engineering and Automation; Autonomous Systems; Autonomiset järjestelmät; Sähkötekniikan korkeakoulu; School of Electrical EngineeringAugmented reality human machine interface is demonstrated in the cabin of a forest machine outdoors for the first time in real time. In this work, we propose a system setup and a real-time capable algorithm to augment the operator’s visual field with measurements from the forest machine and its environment. In the demonstration, an instrumented forestry crane and a lidar are used to model the pose of the crane and its surroundings. In our approach, a camera and an inertial measurement unit are used to estimate the pose of the operator’s head in difficult lighting conditions with the help of planar markers placed on the cabin structures. Using the estimate, a point cloud and a crane model are superimposed on the video feed to form an augmented reality view. Our system is tested to work outdoors using a forest machine research platform in real time with encouraging initial results.Item Automatic Speech Recognition for Northern Sámi with comparison to other Uralic Languages(The Research Group on Artificial Intelligence (RGAI), 2016) Smit, Peter; Leinonen, Juho; Jokinen, Kristiina; Kurimo, Mikko; Signaalinkäsittelyn ja akustiikan laitos; Department of Signal Processing and Acoustics; Speech Recognition Research Group; Sähkötekniikan korkeakoulu; School of Electrical EngineeringSpeech technology applications for major languages are becoming widely available, but for many other languages there is no commercial interest in developing speech technology. As the lack of technology and applications will threaten the existence of these languages, it is important to study how to create speech recognizers with minimal effort and low resources. As a test case, we have developed a Large Vocabulary Continuous Speech Recognizer for Northern Sámi, an Finno-Ugric language that has little resources for speech technology available. Using only limited audio data, 2.5 hours, and the Northern Sámi Wikipedia for the language model we achieved 7.6% Letter Error Rate (LER). With a language model based on a higher quality language corpus we achieved 4.2% LER. To put this in perspective we also trained systems in other, better-resourced, Finno-Ugric languages (Finnish and Estonian) with the same amount of data and compared those to state-of-the-art systems in those languages.
