- Automated and connected traffic systems with cooperative functionality need effective testing. One way to enable such testing is to represent the current traffic environment by co-simulating different simulators using a communication layer between the simulators for cooperative functionality. With this approach, this paper presents a platform with its included simulators (vehicle, pedestrian, and traffic simulators), the used run-time infrastructure (RTI) for co-simulation, and the connection to the Unreal Engine based visual system for the simulators. The architecture was tested with two vehicle simulators (one autonomous bus and a truck), one pedestrian simulator, and one traffic simulator connected using a cloud-based service for the RTI.

- BACKGROUNDTraumatic acute subdural hematomas (ASDHs) are associated with high rate of morbidity and mortality, especially in elderly individuals. However, recent reports indicate that the morbidity and mortality rates might have improved.OBJECTIVETo evaluate postoperative (30-d) mortality in younger vs elderly (70 yr) patients with ASDH. Comparing younger and elderly patients, the secondary objectives are morbidity patterns of care and 6 mo outcome according to Glasgow outcome scale (GOS). Finally, in patients with traumatic ASDH, we aim to provide prognostic variables.METHODS This is a large-scale population-based Scandinavian study including all neurosurgical departments in Denmark and Sweden. All adult (18 yr) patients surgically treated between 2010 and 2014 for a traumatic ASDH in Denmark and Sweden will be included. Identification at clinicaltrials.gov is NCT03284190.EXPECTED OUTCOMESWe expect to provide data on potential differences between younger vs elderly patients in terms of mortality and morbidity. We hypothesize that elderly patients selected for surgery have a similar pattern of care as compared with younger patients. We will provide functional outcome in terms of GOS at 6 mo in younger vs elderly patients undergoing ASDH evacuation. Finally, clinical useful prognostic factors for favorable (GOS 4-5) vs unfavorable (GOS 1-3) will be identified.DISCUSSION An improved understanding of the clinical outcome, treatment and resource allocation, clinical course, and the prognostic factors of traumatic ASDH will allow neurosurgeons to make better treatment decisions.

- Recent technical developments have resulted in the increased use of Virtual Reality and Head Mounted Displays (HMDs) for entertainment and industrial purposes (Bengtson, Borsos, & Krupenia, 2017). A persistent problem associated with the use of HMDs for VR is that when moving within a virtual environment, the user can experience motion sickness and disorientation resulting in reduced ease of use or efficiency. The purpose of the current research was to establish which movement-based design principle(s) is/are best suited for a virtual environment. Three movement techniques were implemented and tested; a fading teleport, a drag/floating movement, and a hybrid concept. Of interest were motion sickness, disorientation, ease of use, and efficiency. Results indicated that the fading teleport technique best supported ease of use and also reduced disorientation. Further investigation into the teleportation technique and how it can be further improved is suggested.
