Journal of Quality in Maintenance Engineering | Year: 2017
Purpose - For the expected increase in the capacity of existing transportation systems and efficient energy utilisation, smart maintenance solutions that are supported by online and integrated condition monitoring systems are required. Industrial internet is one of the smart maintenance solutions which enables real-Time acquisition and analysis of asset condition by linking intelligent devices with different stakeholders' applications and databases. The purpose of this paper is to present some aspects of industrial internet application as required for integrating weather information and floating road condition data from vehicle mounted sensors to enhance effective and efficient winter maintenance. Design/methodology/approach - The concept of real-Time road condition assessment using in-vehicle sensors is demonstrated in a case study of a 3.5 km road section located in Northern Sweden. The main floating data sources were acceleration and position sensors from a smartphone positioned on the dash board of a truck. Features extracted from the acceleration signal were two road roughness estimations. To extract targeted information and knowledge, the floating data were further processed to produce time series data of the road condition using Kalman filtering. The time series data were thereafter combined with weather data to assess the condition of the road. Findings - In the case study, examples of visualisation and analytics to support winter maintenance planning, execution and resource allocation were presented. Reasonable correlation was shown between estimated road roughness and annual road survey data to validate and prove the presented results wider applicability. Originality/value - The paper describes a concept of floating data for an industrial internet application for efficient road maintenance. The resulting improvement in winter maintenance will promote dependable, safe and sustainable transportation of goods and people, especially in Northern Nordic region with harsh and sometimes unpredictable weather conditions. © Emerald Publishing Limited.

Urbanization acts as a filter on bird species behavioral traits so that only few species can tolerate urban constraints. We analyzed how behavioral traits (nesting, feeding, and migratory habits) of breeding bird species affect their frequency of occurrence in the urban centers of 38 European towns. We used binary logistic regression analysis to predict the bird species traits belonging to each trait group. A total of 108 species (21% of the European breeding bird species) were found to breed in the European town centers. According to our broad-scale analyses the bird species most frequently breeding in town centers nest in buildings and/or buildings have diverse diets, in trees (40%) and are resident omnivores, or relied on seeds or fruits as their sources of food. However, almost all bird species also fed on arthropods (92%) during the breeding season. Only a few urban bird species bred on the ground. Four out of the studied 108 species were non-native and five species were predators. Our broad-scale results from Europe indicate that bird species with different behavioral traits can respond differently to urbanization. Bird species that nest in cavities/buildings have diverse diets, that benefit a resident way-of-life, may have an advantage in living and settling in European town centers. Our results from Europe may provide insights related to the development of bird assemblages in the urban core areas of the New World. © 2014 Springer Science+Business Media New York

The performance of many organizations depends on their ability to utilize their IT service systems effectively. This implies the necessity to optimize the relationships between IT service provider(s), IT management and customers. In this paper, we propose a model of IT service system based on Service-Dominant Logic. This model is considered within an internal organizational context where an IT department offers IT services to other business units. We define three types of actors and the relationships between them including information exchange. We further recommend that customers should be actively co-producing IT service offerings and the IT service provider should participate in the design of business processes in the organization. A case study shows how the IT serv ice system in Lapland University of Applied Sciences is analyzed and redesigned based on the proposed model. © Springer International Publishing Switzerland 2015.

Bendability is an important material property for ultra-high strength steel. The bendability of a certain material is expressed as the minimum bending radius Rmin of the inner surface of the bend and expressed in multiples of the sheet thickness. Bendability is limited by either cracking on the surface or the edges of the bend or by surface waviness that usually precedes cracking on the outer surface. Surface waviness is a form of strain localization in bending and the intensity of the phenomenon is dependent on e.g. The punch radius, the lower tool width and the sheet thickness. In this study the bendability of a S960 grade steel was investigated using optical strain measurements of three-point bending tests to determine the strain level and the bending angle when localization starts with different punch radii. The unbent samples were marked with a grid using laser marking and the deformation was measured with the GOM ARGUS strain analysis system after bending. The quality of the bend was also evaluated visually. In addition, tensile tests were performed and evaluated with the GOM ARAMIS deformation analysis system to investigate the local mechanical properties of the studied steel. The results of strain measurements and visual evaluation were then compared. It was found that beyond a certain angle the maximum strain across the bend did not significantly change with further increases in the bending angle when the punch radius was at least three times the sheet thickness. But with smaller punch radii the maximum strain increased almost linearly with increasing bending angle until fracture appeared. With the smaller punch radii deformation localizes and surface waviness begins to form in smaller bending angles because the deformation is concentrated in a narrow zone. © (2015) Trans Tech Publications, Switzerland.

Engineering competences form a potential basis for entrepreneurship. There are pressures to find new approaches to entrepreneurship education (EE) in engineering education, as the traditional analytical logic of engineering does not match the modern view of entrepreneurship. Since the previous models do not give tangible enough tools on how to organise EE in practice, this article aims to develop a new framework for EE at the university level. We approach this aim by analysing existing scientific literature complemented by long-term practical observations, enabling a fruitful interplay between theory and practice. The developed framework recommends aspects in EE to be emphasised during each year of the study process. Action-based learning methods are highlighted in the beginning of studies to support students’ personal growth. Explicit business knowledge is to be gradually increased only when professional, field-specific knowledge has been adequately accumulated. © 2015 SEFI

In this paper, we present the IoT Owl, which is the result of exploration of the use of textile materials as part of a visualization system. After hectic workshop days, our development team had several ideas to be prototyped. The IoT Owl is a prototype of a system that, via lighting and movement, displays the presence information from a sensor at a remote location, based on scan of available Bluetooth devices. It can be completely operated via Internet. The purpose of the IoT Owl is to help the user to avoid a rush hour in a chosen public space and meet the right people at the right time for example during lunch hours. The IoT Owl can calculate the crowd amount but it can also recognize familiar devices. We present a concept design for the device and create an initial prototype with features and technology in it.

High Strength Steels became more popular as a construction material during last decade because of their increased availability and affordability. On the other hand, even though general use of Advanced High Strength Steels (AHSS) is expanding, the wide utilization is limited because of insufficient information about their behaviour in structures. The most widely used technique for joining steels is fusion welding. The welding process has an influence not only on the welded connection but on the area near this connection, the so-called heat affected zone, as well. For that reason it is very important to be able to determine the properties in the heat affected zone (HAZ). This area of investigation is being continuously developed in dependence on significant progress in material production, especially regarding new types of steels available. There are currently several types of AHSS on the world market. Two most widely used processes for AHSS production are Thermo-Mechanically Controlled Processing (TMCP) and Quenching in connection with Tempering. In the presented study, TMCP and QC steels grade S960 were investigated. The study is focused on the changes of strength, ductility, hardness and impact strength in heat affected zone based on the used amount of heat input. © Published under licence by IOP Publishing Ltd.

Coopetition, namely the co-presence of cooperation and competition, is a new strategy that goes beyond the established business paradigms of competition and cooperation. This type of strategy is relevant in tourism destinations, for instance in theme parks, where competing, co-located companies also collaborate. In this paper, we address the temporal dynamics of interorganizational relationships in Finnish and Italian theme parks (i.e. Lapland and Riviera Romagnola). Our comparative study shows that cooperation and coopetition among tourism businesses often shift from a prevalently short-term basis to a long term one when public and private stakeholders understand the benefits accruing to cooperation in terms of enhancement of the brand image of the destination and attraction of a higher number of visitors, by leveraging the destination's multifaceted assets. © 2012 Taylor & Francis.
