The past few years have seen a dramatic increase in the popularity and adoption of XML, the eXtensible Markup Language. This explosive growth is driven by its ability to provide a standardized, extensible means of including semantic information within documents describing semi-structured data. This makes it possible to address the shortcomings of existing markup languages such as HTML and support data exchange in e-business environments.

The purpose of this book is to provide a theory of Digital Power Electronics and its applications. It is well organized in 400 pages and over 300 diagrams. Traditionally, Power Electronics is analyzed by the analog control theory. For over a century, people have enjoyed analog control in Power Electronics, and good results in the analog control and its applications in Power Electronics mislead people into an incorrect conclusion that Power Electronics must be in analog control scheme. The mature control results allowed people to think that Power Electronics is a sunset knowledge.We would like to change these incorrect conclusions, and confer new life onto the traditional Power Electronics. In this book the authors initially introduce the digital control theory applied to Power Electronics, which is completely different from the traditional control scheme.

Trauma in general is a major cause of morbidity and mortality worldwide, and causes more loss of productive years than ischemic heart disease and malignancy together. Cardiothoracic trauma occurs in 60% of multitrauma patients and is 2-3 times more common than intra-abdominal visceral injuries. It constitutes 25% of traumatic deaths and contributes significantly to at least another 25% of these fatalities. Though only about 15% of chest trauma requires operative intervention, a considerable number of preventable deaths occur due to inadequate or delayed treatment of otherwise an easily remediable injury. The aim of this study was to describe rare but serious and sometimes fatal entities in patients with cardiothoracic trauma sustained in two Scandinavian countries, and to determine the outcome.
