Conference paper (peer-reviewed)abstract
- COSIVU is a three year collaborative research project that ended in September 2015 and which has been funded within the European Green Car Initiative (now the European Green Vehicle Initiative). COSIVU addresses one of the most critical technical parts in fully electrical vehicles (FEV) besides the energy storage system: the mechatronic drive-train unit. The COSIVU project has delivered a new system architecture for multiple wheel drive-trains by a smart, compact and durable single-wheel drive unit with integrated electric motor, full silicon carbide (SiC) power electronics (switches and diodes), a novel control and health monitoring module with wireless communication, and an advanced ultra-compact cooling solution. DfR utilizing FEM simulations ensures first time right solutions. This paper presents the main results including the architecture of the drive train solution as well as the modular design of the inverter based on Inverter Building Blocks, one per phase. Performance tests are presented here for the first time for both the heavy duty commercial vehicle solution performed in a test rig by Volvo, and the tests of the COSIVU solution adapted to a passenger car done by Elaphe.

Issues in Child and Adolescent Inpatient Assessment and Evaluation After Discharge : Protocol for App Development and a Randomized Controlled Trial

Journal article (peer-reviewed)abstract
- BACKGROUND: New methods are needed for collecting data of in- and outpatients and for improving outpatient compliance after discharge. Mobile technologies, such as smartphone apps, have shown promising results, (eg, helping unwell people by offering support and resources). Screening for the condition, including comorbidities, is a vital part of psychiatric care. Comorbid conditions, especially in emergency evaluation, are often missed, leading to inaccurate diagnosis and treatment. One way of improving diagnostic accuracy is to use a structured diagnostic process. Digitalized screening and follow-up have the advantage of making administration and scoring easier and less time consuming, thereby increasing response rate. To address these problems, we decided to create a smartphone app called The Blue App. The Blue App was developed through 6 steps, described in the manuscript. OBJECTIVE: The aim of this paper is to describe (1) the development of The Blue App and (2) 2 planned research studies to evaluate the app. METHODS: Two studies will be performed. Study 1 has a descriptive design, mapping comorbidities before and after the introduction of The Blue App. Study 2 has a randomized controlled design, measuring compliance with outpatient treatments as well as depressive symptoms, rated as changes in Montgomery-Asberg Depression Scale scores during a 1-year follow-up. RESULTS: We have described app development. Data collection for Study 1 started in autumn 2017. Study 2 will start in autumn 2018. We expect to have enrolled the 150 patients in Study 2 by December 2019. Final results will be published in a scientific journal. CONCLUSIONS: A technically advanced and easy-to-use Web-based mobile phone app corresponding to the unit's needs was developed, and 2 studies are planned to evaluate its usefulness.

Reliability investigation on SiC BJT power module
- 2016
-
In: PCIM Europe 2016. - : Institute of Electrical and Electronics Engineers Inc.. - 9783800741861 ; , s. 1063-1071
-
Conference paper (peer-reviewed)abstract
- In this paper reliability investigation results for a power module fully based on silicon carbide (SiC) devices are presented. The module comprises four SiC bipolar junction transistors (BJT) and four SiC diodes in half-bridge configuration and is part of a newly developed 3-phase inverter for construction vehicles as well as for passenger car applications. The reliability investigations include electro-thermal and thermo-mechanical finite element simulations as well as power cycling tests with subsequent failure analyses. Furthermore, a double-sided cooling approach for the SiC BJT power module will be described and its thermal performance compared to the single-sided cooling version.
