Thermal design of electric traction machines for high performance HEV drivetrains is a challenging task. Unlike conventional HEV traction machines, these machines are subject to continuous operation at or near their thermal limits during race-track driving, and so thermal management is of paramount importance to the mass and size of the machine. This article presents the main challenges related to

This paper forms part of a broader study on the design optimization of a high speed switched reluctance motor for automotive traction applications. Due to the high speed operation and resulting high electrical frequency, it is of extreme importance that the different loss components of this motor are accurately calculated. In this study, several effects are observed that influence the accurate mea

This paper forms part of a broader study on the design of an unconventional, high speed, switched reluctance machine (SRM), for automotive traction applications making use of soft magnetic composite (SMC) material. The aim is to have this machine operate at a fundamental frequency of up to 4 kHz. Another characteristic is that switched reluctance machines tend to be operated in deep saturation a l

Conductive Electric Road Systems (ERS) appear as a promising solution for the electrification of transportation, particularly for heavy vehicles and long distance trips, but also for light vehicles. Significant research efforts are currently devoted to the development of conductive ERS systems, with up to 4 pilot test sites with different technologies in operation only in Sweden. This article asse

This article presents the first thermal experiments conducted on a novel cooling concept applied to a high speed switched reluctance machine topology for traction applications. By circulating the coolant in between the coils and the stator poles the winding and the stator iron are virtually thermally decoupled. A test motorette is used to demonstrate the potential of the cooling concept at current

Electrifying road transport is seen as one of the key components in decreasing the carbon footprint of the society as a whole. Recent developments in electric drivetrain and battery technology have helped to design vehicles with ranges that make them independent of public charging infrastructure during most sub-urban and commuting trips. Once long-haul trips are planned, however, these vehicles re

This paper focuses on the development of a machine design environment for numeric modelling and analysis of radial flux machines. The design environment is based on Matlab/(Octave) environment, which calls numeric field analysis by FEMM/(Opera-2D). The analysis tool is intended for educational purposes; however it has proved to be a powerful research tool especially at early design stages.

Our study aims to investigate the relationship between social participation and loneliness among Chinese older adults and examine how their views of social change moderate the strength of this relationship. The cross-sectional nationwide data from the China Longitudinal Aging Social Survey (CLASS) was used. Results show that increased online participation and community participation were associate

Multi-talker noise impedes children's speech processing and may affect children listening to their second language more than children listening to their first language. Evidence suggests that multi-talker noise also may impede children's memory retention and learning. A total of 80 culturally and linguistically diverse children aged 7 to 9 years listened to narratives in two listening conditions:

We propose the Virtual Bingo Blower (VBB) as a way to generatecredible risk and ambiguity in computerized experiments. Using aphysics engine—a computer simulation of a physical system—the VBBsimulates a conventional bingo blower. Different aspects of the VBB,such as the number of balls, their color, and their speed, can be easilymodified. In an online experiment, we measure ambiguity attitudes and

Mechanical testing of articular cartilage yields highly variable results, posing challenges for tissue characterization. Many factors cause variability, one is sample geometry. Using in-situ phase-contrast enhanced synchrotron micro-tomographs of cartilage samples while tested in unconfined compression (stress relaxation) our group found high variability in the mechanical response. Since all sampl

Many scholars are struggling to find their way in a reality characterised by a growing sense of urgency to solve pressing social problems and a diminishing faith in traditional institutions, such as universities, spreading through society. Some scholars respond by turning towards activism, which manifests in overtly ideological teaching, increasingly radical critical research agendas, and even pub

B-cell progenitor acute lymphoblastic leukemia (BCP-ALL) is the most common childhood malignancy and is driven by multiple genetic alterations that cause maturation arrest and accumulation of abnormal progenitor B cells. Current treatment protocols with chemotherapy have led to favorable outcomes but are associated with significant toxicity and risk of side effects, highlighting the necessity for

High racial disparities between Europeans and Africans and high skill premiums are recurrent themes in the literature on inequality in colonial Africa. However, their determinants and effects on inequality remain underexplored. This paper investigates wage inequality, skill premiums, and racial discrimination in British Tanganyika from c. 1920 to 1960. It provides first estimates for wage inequali

The aim of the creation of this cohort was to investigate patterns of health and health care utilisation before and during the COVID-19 pandemic, overall and in relation to specific diagnoses, among people with intellectual disabilities (ID) compared to the general population. People living in Skåne, the southernmost region of Sweden, on 1st of January 2014 with at least one diagnosis of ID (ICD-1
