Comparison of Induction and PM Synchronous motor drives for EV application including design examples [PDF]

open access: yes, 2012
Three different motor drives for electric traction are compared, in terms of output power and efficiency at the same stack dimensions and inverter size. Induction motor (IM), surface-mounted permanent-magnet (PM) (SPM), and interior PM (IPM) synchronous ...

Comparison of unitary transforms [PDF]

open access: yes, 2002
We analyze the problem of comparing unitary transformations. The task is to decide, with minimal resources and maximal reliability, whether two given unitary transformations are identical or different.

Multiple comparisons [PDF]

open access: yesBMC Biology, 2015
Oat plants grown at an agricultural research facility produce higher yields in Field 1 than in Field 2, under well fertilised conditions and with similar weather exposure; all oat plants in both fields are healthy and show no sign of disease. In this study, the authors hypothesised that the soil microbial community might be different in each field, and

Pyramidal Systems in Resistance Training

open access: yesEncyclopedia, 2021
Pyramidal systems refer to a particular type of resistance training in which sets are performed with increasing (or decreasing) weight, in such a way that the number of repetitions is low when the weight is high (and vice versa). Multiple implementations

The $K$-groups and the index theory of certain comparison $C^*$-algebras [PDF]

open access: yes, 2010
We compute the $K$-theory of comparison $C^*$-algebra associated to a manifold with corners. These comparison algebras are an example of the abstract pseudodifferential algebras introduced by Connes and Moscovici \cite{M3}. Our calculation is obtained by

Mathematical Modelling of Solar Thermal Collectors and Storages

open access: yesActa Technologica Agriculturae, 2019
Block-oriented modelling is a powerful tool in system design. The models developed this way can be used to study various systems, such as solar thermal systems. In the work presented, main goal is to compare different mathematical models of solar thermal
