Security research and training using cyber-physical systems (e.g., automotive networks) is challenging because of the need to replicate the interactions between the hardware components and the control software of the systems. These interactions are challenging to replicate due to dynamic inputs in real-world environments that cause various interactions of hardware components and control softwar...

Timing isolation is critical for automotive systems. Real-time virtualization, such as RT-Xen, is a promising technique to integrate legacy automotive systems onto a powerful multi-core platform for achieving better performance and lower cost without breaking the timing isolation. However, the real-time virtualization has never been evaluated with real automotive applications in a non-simulatio...

aims: the performance of the vision system as the most important sense of the body depends largely on the optimum lighting of an environment. it is one of the factors that lead to vision problems such as visual fatigue of employees. this study aimed to assess the local lighting and visual fatigue among the official staff of an automotive industry development and research center which was conduc...

In this paper, a novel foam-filled double ellipse tube (F-DET) is proposed. First, the circle and ellipse tubes with three different configurations(hollow, foam-filled, double foam-filled) are investigated under axial and oblique impact by using the nonlinear finite element code LS-DYNA. The numerical results showed that the F-DET tube has the best crashworthiness performance than tubes with ot...

Developing an appropriate design process for a conceptual model is a stepping stone toward designing car bodies. This paper presents a methodology to design a lightweight and modular space frame chassis for a sedan electric car. The dual phase high strength steel with improved mechanical properties is employed to reduce the weight of the car body. Utilizing the finite element analysis yields tw...

A study is conducted to determine the sensitivity of 2 topologically distinct metamodel types to variations in the experimental design brought about by sequential adaptive sampling strategies. The study focuses on examples encountered in crashworthiness design. Three sampling strategies are considered for updating the experimental designs, namely (i) a single stage approach, (ii) a sequential a...

A significant proportion of motor vehicle crash fatalities are potentially preventable with improved acute care. By increasing the accuracy triage more victims could be transported directly to best suited care facility and provided optimal We hypothesize that On Scene Injury Severity Prediction (OSISP) algorithms, developed utilizing machine learning methods, have potential improve by complemen...

The past years have seen growing investments in the area of product lifecycle management (PLM) by the automotive sector. Due to its complex development cycle, the automotive OEM has begun to adopt the supplier integration into its product development process. To respond to this new trend, the PLM system needs to evolve to support the collaboration and partnership management between the automoti...

In this paper, crashworthiness characteristics of conical steel tubes stiffened by annular rings and rigid polyurethane foam are investigated. For this purpose, wide circumferential rings are created from the outer surface of the conical tube at some determined areas along tube length. In fact, this method divides a long conical tube into several tubes of shorter length. When this structure is ...
