A method that identifies the optimal components set, joint designs and corresponding subassembly partitioning for a Body-In-White (BIW) made of the aluminium space frame (ASF) is presented where the structural stiffness, dimensional integrity and components manufacturing / assembly cost are considered as the objectives. The optimization problem is posed as a simultaneous determination of the lo...

The paper presents a joint predictive maintenance and spare parts provisioning policy for gradually deteriorating multicomponent systems with complex structure. The decisionmaking process related to maintenance, spare parts ordering, as well as inspections scheduling is based on both RUL prediction and structural importance measure. Moreover, economic dependency between components is studied an...

Present study focuses on the micro-structural and mechanical behavior effect of friction time for similar (AISI 316-AISI 316 and AISI 304-AISI 304) and dissimilar (AISI 304-AISI 316) joint during continuous drive friction welding. The welding carried out with different friction time: 6.5, 8.5 and 10 s while kept all other conditions constant. The effect of that time on the strength, structural ...

The purpose of this review is to explore the mounting evidence that primary osteoarthritis is secondary to childhood disorders such as dysplasia and/or to subtle morphologic and structural to subtle morphologic and structural abnormalities of the proximal femur and/or acetabulum that were previously unrecognized or underestimated. These structural deformities lead to early impingement through r...

Previous neuroimaging investigations in attention-deficit/hyperactivity disorder (ADHD) have separately identified distributed structural and functional deficits, but interconnections between these deficits have not been explored. To unite these modalities in a common model, we used joint independent component analysis, a multivariate, multimodal method that identifies cohesive components that ...

7000 series aluminum alloys are widely used in the automotive industries for structural lightweight components due to their exceptional high strength to weight ratio. however, this class of aluminum alloy is difficult to join by conventional fusion welding techniques so friction stir welding (fsw) widely is used for welding this alloys. the process has been demonstrated to be effective and is c...

This paper presents an extension of our previous work on decomposition-based assembly synthesis for structural stiffness [1], where the 3D finite element model of a vehicle body-inwhite (BIW) is optimally decomposed into a set of components considering the stiffness of the assembled structure under given loading conditions, as well as the manufacturability and assembleability of components. Two...

Open innovation has recently attracted considerable attention in both academic and practical fields. The effects of information and communication technology (ICT) and inand extra-role knowledge sharing (KS) on open innovation remain unknown. This study aims to fill this research gap. We believe that ICT application facilitates two types of KS that can enhance internal and external research and ...
