     School of Engineering | A4 Artikkeli konferenssijulkaisussa
    Battery electric city bus model has been created and the simulation results compared against the measured results from the full scale city bus developed for heavy vehicle research. The model utilizes multi-physics modelling approach with multiple-domains from friction-tyre and transmission model toelectrical drive and a simplified battery model. The modelled and measured motor torque, current and voltages in the battery and inverter and the bus speed were compared under a driving cycle based on a local bus line. The simulated results were in good agreement with the experimental measured results; theerror between the simulated and measured energy consumption was 1.4 %. The measured average energy consumption was 0.581 kWh/km while the simulation estimated 0.589 kWh/km.
  • Exploring the Recurrent Problems in the Last Planner Implementation on Construction Projects
    (2015) Dave, Bhargav; Hämäläinen, Juho-Pekka; Koskela, Lauri
     School of Engineering | A4 Artikkeli konferenssijulkaisussa
    Traditionally, production control on construction sites has been a challenging area, where the ad-hoc production control methods foster uncertainty - one of the biggest enemies of efficiency and smooth production flow. The Last Planner System® has been one of the most popular lean construction tools that offers a solution to tackle the problems of production management on construction sites. Since its inception almost 20 years ago, construction companies across the world have implemented Last Planner with reported success. However, there have also been reports of challenges in a number of areas whilst implementing the Last Planner. These challenge areas limit the effectiveness of Last Planner if not tackled properly. Some of the biggest challenges appear to be partial implementation of Last Planner; lack of standardised flow of reporting between shorter planning functions such as weekly and daily planning to long range plans (i.e. Phase and Master plans); lack of attention to long range plans; inability to deploy the collaborative aspects and lack of recognition of information systems. In this paper some of these challenges are explored through review of past literature and also through direct observation of Last Planner implementations. The challenges are categorised in two major areas and potential solution candidates are presented.
  • GEONAVPOS: Seminar publications on Geodesy, Navigation and Positioning
    (2013) Andrei, Octavian (editor); Vermeer, Martin (editor)
     School of Engineering | C2 Toimitettu kirja, kokoomateos, konferenssijulkaisu tai lehden erikoisnumero
    Modern geodesy may be defined as "the science of precise georeferencing and change monitoring on or above the Earth’s surface". Modern geodesy relies on space technology and integrates complex Earth observation systems and modelling of geospatial data at higher accuracy in order to understand and predict how the solid Earth, atmosphere, and oceans work as a system. Modern geodesy applications include precise determination of position and velocity of points on the surface of the Earth, precise determination of the shape and changes of the Earth’s ocean and land surfaces, or precise mapping of the spatial and temporal features of the gravity field. Navigation and geodesy relate both on positioning (location) information. Although a connecting element, positioning also makes the difference between navigation and geodesy. In navigation, the positioning information is required instantaneously or almost instantaneously with a certain latency (real-time). On the other hand, in traditional geodesy the position information is obtained post-mission after post-processing calculations. Usually, these calculations are carried out under the assumption that the points are fixed or undergo a very slow movement. However, in navigation, the points are variable, therefore time dependent. The Maa-6.3255 Seminar on Geodesy, Navigation and Positioning is offered to both master and doctoral students of Aalto University. The seminar builds on active participation between the theory and practice, using a student-centred approach for teaching. This publication consists of the best 12 student works prepared by the seminar participants (i.e., 24 students) during 2011-2013: (01) Post-glacial rebound: modelling, measurement, significance on society (02) The Current State of GPS Meteorology and Climatology (03) Matlab Application in VLBI Data Analysis (04) Science Network GNSS-verkon tasoitus ja antennikorkeuden ja - tyypinvaikutus koordinaatteihin (05) Koordinaattien laskenta Precise Point Positioning – menetelmällä (06) GOCE User Toolboxin käyttö Itämeren meritopografian visualisoinnissa (07) GNSS – Risks and threats (08) Global Navigation: Introduction to Satellite Based Augmentation System over Indian Region (09) Positioning Techniques of Modern Smartphones (10) Hybrid Positioning with a Smartphone (11) Dexter Industries GPS sensor for Lego Mindstorms NXT (12) GPS Wildlife Tracking
  • Global buckling and post-buckling of web-core sandwich and stiffened panels: sensitivity to general corrosion
    (2014) Jelovica, Jasmin; Romanoff, Jani
     School of Engineering | C2 Toimitettu kirja, kokoomateos, konferenssijulkaisu tai lehden erikoisnumero
    Corrosion can lead to reduction of structural stiffness and strength. This paper investigates the influence of a reduction in the thickness of the plates as a result of general corrosion on sandwich panel buckling load and onset of plasticity. The results are compared to the stiffened panel of the same in-plane and bending stiffness. Current guidelines for corrosion protection threat these two structures equally. Load-shortening curves are obtained with the finite element method, with the kinematics being represented using two approaches: (1) equivalent single-layer with first-order shear deformation theory, and (2) a three-dimensional model of the actual geometry of the structure, modeled using shell and connector elements. The former is also used to identify the influence of corrosion on the stiffness coefficients and, consequently, the buckling load, also via analytical equation. The decrease of the buckling load is found higher in sandwich panel than in stiffened panel. The reduction is especially high in the case of the diffusion of moisture (water) into the core. The reason for the higher sensitivity of sandwich panel is a larger reduction of transverse shear stiffness opposite to the stiffener direction due to corrosion.

  • Optimized patterns for digital image correlation
    (2013) Bossuyt, Sven
     School of Engineering | B3 Vertaisarvioimaton artikkeli konferenssijulkaisussa
    This work presents theoretical background on a novel class of strain sensor patterns. A combination of morphological image processing and Fourier analysis is used to characterize gray-scale images, according to specific criteria, and to synthesize patterns that score particularly well on these criteria. The criteria are designed to evaluate, with a single digital image of a pattern, the suitability of a series of images of that pattern for full-field displacement measurements by digital image correlation (DIC). Firstly, morphological operations are used to flag large featureless areas and to remove from consideration features too small to be resolved. Secondly, the autocorrelation peak sharpness radius en the autocorrelation margin are introduced to quantify the sensitivity and robustness, respectively, expected when using these images in DIC algorithms. For simple patterns these characteristics vary in direct proportion to each other, but it is shown how to synthesize a range of patterns with wide autocorrelation margins even though the autocorrelation peaks are sharp. Such patterns are exceptionally well-suited for DIC measurements.

    The third Open Source Geospatial Research & Education Symposium (OGRS) was held in Helsinki, Finland, on 10 to 13 June 2014. The symposium was hosted and organized by the Department of Civil and Environmental Engineering, Aalto University School of Engineering, in partnership with the OGRS Community, on the Espoo campus of Aalto University. These proceedings contain the 20 papers presented at the symposium. OGRS is a meeting dedicated to exchanging ideas in and results from the development and use of open source geospatial software in both research and education.  The symposium offers several opportunities for discussing, learning, and presenting results, principles, methods and practices while supporting a primary theme: how to carry out research and educate academic students using, contributing to, and launching open source geospatial initiatives. Participating in open source initiatives can potentially boost innovation as a value creating process requiring joint collaborations between academia, foundations, associations, developer communities and industry. Additionally, open source software can improve the efficiency and impact of university education by introducing open and freely usable tools and research results to students, and encouraging them to get involved in projects. This may eventually lead to new community projects and businesses. The symposium contributes to the validation of the open source model in research and education in geoinformatics.

    While non-destructive evaluation (NDE) of reinforced concrete structures (RCS) in civil engineering applications has a long history, as well as NDT of the pressurized (metallic) components of a nuclear power plant, testing of concrete constructions in nuclear installations has partly been neglected. At the same time there are many specific challenges to NDE that justify a dedicated international event. The International Conference on Non-destructive Evaluation of Concrete in Nuclear Applications (NDE NucCon) was co-organized by VTT Technical Research Centre of Finland, Aalto University, Finland, and Bundesanstalt für Materialforschung und -prüfung (BAM), Germany. The event was sponsored by the Euratom projects ACES and PREDIS. In January 2023 about 70 participants gathered for three days in the Dipoli convention center in Espoo, Finland to listen to about 50 presentations from 15 countries, complemented by an exhibition with international instrument manufacturers and service providers. This book includes all peer reviewed manuscripts submitted to the conference. The reader will find a large variety of subjects from basic research, new inspections methods and case studies in actual facilities. We, the organizers m hope you will enjoy the read.
