    Proceedings of the International Conference on Non-destructive Evaluation of Concrete in Nuclear Applications - NDE NucCon 2023
    (Aalto University, 2023) Al-Neshawy, Fahim; Ferreira, Miguel; Bohner, Edgar; Kekäläinen, Pirkko; Oey, Tandré; Lay, Vera; Rakennustekniikan laitos; Department of Civil Engineering; Mineral-based materials and mechanics; Insinööritieteiden korkeakoulu; School of Engineering
    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.

    (IOP, 2019) Alam, Sadaf; Lahdelma, Risto; Konetekniikan laitos; Department of Mechanical Engineering; Rakennetun ympäristön laitos; Department of Built Environment; Insinööritieteiden korkeakoulu; School of Engineering
    The European Union 2020 energy targets seems to be a progressive, however, it still needs to be worked upon. The implementation of Nearly Zero Energy Buildings (nZEBs) as the building target represents one of the biggest challenges to increase energy savings and minimize greenhouse gas emissions. In this paper detached house has been modelled using dynamic simulation tool and the energy efficiency measures, concerning different technologies for envelope systems and technical systems, were set up as parameters in dynamic simulation tool and simulated and analysed. The objective of this paper is to define the heating, cooling, and electricity demand of a residential building in a cold climate region. The façade parameters were optimized for the best possible energy performance, to be used as design guidelines for facades in low and nearly zero energy buildings for architects and engineers. The purpose of the study is to give guidelines of office buildings facade design from the perspective of energy-efficiency and daylighting to architects, engineers, real-estate developers, etc.

    Review of the safety engineering techniques for a complex ship system
    (ACEE, 2018) Basnet, Sunil; Valdez Banda, Osiris Alejandro; Kujala, Pentti; Konetekniikan laitos; Department of Mechanical Engineering; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
    Marine industry is leaning towards the autonomous vessels; and advanced technologies are being developed for autonomous operations. However, this rapid technological change has increased the level of complexity in ship systems. As the interactions between components are increasing further and software are getting imbedded into components, the nature of risks in modern systems can be different than in the traditional systems; where the risks were mostly limited to human errors and component failures. However, for identifying risks in modern systems, it is first important to understand the system composition and the behavior of components. Since traditional system-safety engineering techniques, developed for the relatively simpler systems in past, are still dominant in marine industry. These techniques may not be able to cope with the risks due to increasing complexity.This paper reviews and identifies a suitable modelling approach and a risk analysis method for a complex ship system. A modern modeling approach known as Systems-Modeling Language (SysML) and a modern risk analysis method known as Systems-Theoretical Process Analysis (STPA) are reviewed and compared with widely used traditional methods known as the Tree structure method and Fault Tree Analysis. SysML is a graphical modeling language that presents structural composition, component functions, behavior, constraints and requirements of a complex system. STPA is a risk analysis method that aims to identify and mitigate risks in a complex system. The review and comparison results are presented in the paper.The results of this study suggest that the modern methods are more suitable than the traditional methods when the functionality of each method are considered. However, as the modern methods are more detailed, and are focused on the functionality, they are relatively complex and require more resources for the analysis in comparison to the traditional methods. Some viable solutions to improve the drawbacks of SysML and STPA, and possible future research topics are presented.

    Global buckling and post-buckling of web-core sandwich and stiffened panels: sensitivity to general corrosion
    (ICTWS 2014, 2014) Jelovica, Jasmin; Romanoff, Jani; Sovelletun mekaniikan laitos; Department of Applied Mechanics; Marine Technology; Insinööritieteiden korkeakoulu; School of Engineering
    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.

    Exploring the Recurrent Problems in the Last Planner Implementation on Construction Projects
    (Institute for Lean Construction Excellence, 2015) Dave, Bhargav; Hämäläinen, Juho-Pekka; Koskela, Lauri; Rakennustekniikan laitos; Department of Civil and Structural Engineering; Insinööritieteiden korkeakoulu; School of Engineering
    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.

    Striving for Continuous Process Improvement - A Construction Case Study
    (Institute for Lean Construction Excellence, 2015) Dave, Bhargav; Appleby, Charlie; Rakennustekniikan laitos; Department of Civil and Structural Engineering; Insinööritieteiden korkeakoulu; School of Engineering
    Organisations must constantly monitor, measure, evaluate and improve their processes in order to remain competitive. Construction organisations are no different in this aspect and are increasingly realising the need for process improvement due to external and internal pressures. The construction industry is working towards improving its efficiency by implementing process improvement techniques such as Lean Construction along with information and communication systems. Business processes and information technology are closely associated and better results can be achieved by addressing them in an integrated manner. This paper provides details of a case study where an extensive business process improvement exercise was carried out over a period of five years alongside a major Enterprise Information System implementation. All major organisational units were assessed and its processes were modelled and evaluated with a view to improvement within the lean framework. Finally a continuous process improvement framework was put in place to avoid the risk of stagnation. The lean continuous improvement framework resulted in each organisational unit taking responsibility for their own processes ultimately leading to higher profitability and smoother supply chain processes. The case study also demonstrated that even smaller business units and its processes affected the overall value chain in a major way and the importance to analyse the process interdependencies between organisational units.
