We present an experimental study of velocity fluctuations in quasistatic flow of a 2D granular material deformed in a shear apparatus named 1γ2ε [1]. Radjaï and Roux [2] revealed systematic similarities between velocity fluctuations observed in discrete element simulations of quasistatic flow of granular material and turbulent flows in fluids. The character of these velocity fluctuations - named g
This paper focuses on the design and the evaluation of a three-phase permanent magnet synchronous machine (PMSM) that stator core is made of Soft Magnetic Mouldable Composite – SM2C. A radial flux PM machine with modular winding is designed for a high-speed low-voltage automotive application. Manufacturability and a high fill factor of the winding are vital for a low permeability stator core in or
Food and feeding is an important part in bringing up children. It is one way in which children become socialized; it gives rise to both pleasure and anxiety. In this article Marjorie DeVault’s understanding of food management is combined with the concept of responsibilisation. Building on in-depth interviews with mothers from different socio-economic backgrounds and focusing on their different exp
Occupations divide the labor market into separate repositories of skill, where labor market frictions hinder employee mobility between occupations. Such frictions shape the supply of skill, the wage structure of each occupation, and the occupation-specific opportunity cost and marginal utility of self-employment entry. We investigate why self-employment entry is dependent on occupation, using 7 ye
