A multi-perspective method for gear efficiency and contact analysis

Modern gearing applications, in particular electrification, impose new challenges in many different fields of engineering and research. In specific, new demands are imposed on gears, including higher rotational speed, lower noise acceptance, and increased efficiency, as well as increased resistance against pitting and scuffing. To meet these demands, a better understanding of gear contacts is need

Introduction

In the latter half of the 1360s, Catherine became connected to the mantellate, a group of laywomen, most of whom were financially independent widows like Birgitta.

Visions, or revelations, played an enormously important role in late medieval society. So much so that the question what constituted an authentic vision was debated at the highest ecclesiastical levels. Furthermore, the majority of visionaries in this period were women, and visions afforded them with unique opportunities to exercise their abilities in contexts otherwise almost exclusively reservedVisions, or revelations, played an enormously important role in late medieval society.

Applying labour law to micro, small and medium-sized enterprises: : A comparative study of 16 countries

The self-employed and micro, small and medium-sized enterprises (MSMEs) account for the greatest share of employment and make up the largest number of economic units worldwide. However, some countries exclude these economic units from certain obligations under their national labour laws in the belief that such obligations may impair enterprise growth and prosperity. This study considers the ways i
