ABSTRACT In PSS design, hardware and service developers often have different objectives. Lacking to communicate and negotiate them across boundaries might lead to solutions unable to generate market shares and long-term profitability. This paper aims to contribute to the definition of ‘boundary objects’ that facilitate the sharing of knowledge between members of cross-functional teams engaged […]

ABSTRACT In this study, laminated composites consisting of LDPE (Low Density Polyethylene), Al-foil (Aluminum foil)and an adhesive interface layer is focused. The defects like necking in LDPE, Al-foil layer and interfacial delamination can significantly impact the loading capacity of the laminated material. However, the influence mechanisms of the defects are still unclear, and no appropriate […]

ABSTRACT In recent times a service-dominant logic is permeating the design of complex systems. However, in spite of their appeal, initiatives such as Product Service Systems (PSS) have not become mainstream, and methods are lacking to support this transition. This paper argues that methodological guidance, as well as tools for decision support, may be found […]

ABSTRACT Despite significant validation and even qualification efforts, complex industrial product development projects frequently struggle with difficulties in integrating new technologies. A recent example, the introduction of new battery technologies in the Boeing 787 aircraft caused un-desired problems for the manufacturer and drove new practices (Williard et al 2013). The effort and cost of validating […]
Read MoreABSTRACT Self-similar solutions are found for a quadratically cubic second-order partial differential equation governing the behavior of nonlinear waves in various distributed systems, for example, in some metamaterials. They are compared with self-similar solutions of the Burgers equation. One of them describing a single unipolar pulse is shown to satisfy both equations. The other self-similar […]

ABSTRACT Nowadays, it is a great challenge to understand what models shall be used to iteratively translate customer desires into terms that are meaningful for engineering design decision-making. This paper proposes a framework illustrating the iterative evolution of model-based enablers for value during conceptual system design. The framework is developed from the analysis of four […]

Research paper published in Journal of Cleaner Production. Highlights Gasoline car causes the most emissions from its manufacturing and use phases. Local jobs from renewables give positive contribution to social sustainability. Renewable electricity in electric carpool cause least socio-ecological impact. Car Pooling is more cost-effective for those who drive from 2000 to 8500 km. People travel […]
Read MoreABSTRACT The subsurface exploration of other planetary bodies can be used to unravel their geological history and assess their habitability. On Mars in particular, present-day habitable conditions may be restricted to the subsurface. Using a deep subsurface mine, we carried out a program of extraterrestrial analog research – MINe Analog Research (MINAR). MINAR aims to […]

ABSTRACT A modified equation of Burgers type with a quadratically cubic (QC) nonlinear term was recently pointed out as a new exactly solvable model of mathematical physics. However, its derivation, analytical solution, computer modeling, as well as its physical applications and analysis of corresponding nonlinear wave phenomena have not been published up to now. The […]

ABSTRACT Gaussian signal is produced by ordinary random vibration controllers to test the products in the laboratory, while the field data is usually non-Gaussian. Two methodologies are presented in this paper for shaker simulation of wind-induced non-Gaussian vibration. The first methodology synthesizes the non-Gaussian signal offline and replicates it on the shaker in the Time […]
