High-Ratio Voltage Conversion in CMOS for Efficient Mains-Connected Standby

By: Hans Meyvaert,Michiel Steyaert

This book describes synergetic innovation opportunities offered by combining the field of power conversion with the field of integrated circuit (IC) design. The authors demonstrate how integrating circuits enables increased operation frequency, which can be exploited in power converters to reduce drastically the size of the discrete passive components. The authors introduce multiple power converter circuits, which are very compact as result of their high level of integration. First, the limits of high-power-density low-voltage monolithic switched-capacitor DC-DC conversion are investigated to enable on-chip power granularization. AC-DC conversion from the mains to a low voltage DC is discussed, enabling an efficient and compact, lower-power auxiliary power supply to take over the power delivery during the standby mode of mains-connected appliances, allowing the main power converter of these devices to be shut down fully.

Animation between Magic, Miracles and Mechanics

Principles of Life in Medieval Imagery

By: Hans Henrik Lohfert Jørgensen,Laura Katrine Skinnebach,Henning Laugerud

When it comes to images, we are all animists. Deep down, we all know that images can – at least potentially – be alive or come to life. Nowadays, we may tend to rationalize our ingrained animism and explain it away as a mere projection only happening in the space between image and viewer. In the Middle Ages, however, imagery made enthusiastic use of magical, miraculous and mechanical means of animation, empowered and ensouled by both natural and supernatural principles of life. This animist book investigates magic, miracles and mechanics as motors of animation and seeks to understand the living image in solidarity with medieval experience rather than dismissive alienation of it. Effigies did bleed, weep or lactate, either through divine intervention or through hydraulic machinery. Statues did move or speak, either as demonic oracles or as talking heads with implanted speaking tubes. Marvels made by magic or by miracles were real, as real as the wonders of physical mechanics moving bodily matter. We just need to look and listen more carefully to comprehend these fluid realities, even when – especially when – they challenge our received worldview. Animation was by no means uncontested or uncontradicted, but even its stiffest critics knew that gods and demons could intervene in inanimate matter to set it in motion, to speak in tongues and exude the liquids of life.

Exemplum

Model-book Drawings and the Practice of Artistic Transmission in the Middle Ages (ca. 900-ca. 1470)

By: Robert Walter Hans Peter Scheller

During the Middle Ages, artistic ideas were transmitted from one region to another and passed on from one generation to the next, in the form of drawings. This kind of handmade reproduction, 'exemplum' in Latin, was used to record the form and content of works of art. Some of those drawings have survived in 'model books'. The author presents a fascinating account of many and various aspects of these drawings with special emphasis on how they contribute to our understanding of the genesis of medieval works of art. Exemplum will be a standard work of reference for many years to come
