We describe a tool for physical database design based on a combination of theoretical and pragmatic approaches. The tool takes as input a relational schema, the workload defined on the schema, and some additional database characteristics and produces as output a physical schema. For the time being, the tool is tuned towards Ingres. 1 Introduction The design of databases takes place on several l...

Most bituminous adhesives or binders that are used for pavement materials are derived mainly from fossil fuels. Due to the availability of large quantities of biorenewable sources such as triglyceride oils, proteins, starch, and other carbohydrates from different organic sources, there are virtuous technical and economic prospects in utilizing them to produce bio-binders. Recently, through the ...

For different bio-oils d...

Focus of this chapter is the description of the exposure systems used for data acquisition during the exposure to radiofrequency (RF) electromagnetic (EM) fields in bioelectromagnetic investigations. Such a kind of system will be referred to as real-time and can be defined as an EM structure (waveguide or antenna) able to generate and control a known and reproducible EM field and suitable to be...

Increased life expectancy on the one hand and dramatically reduced physical activity in daily life on the other hand are characteristic features of postmodern life. Consequently Homo sapiens is increasingly confronted with the problems associated with accelerated bone loss, osteoporosis and osteoporosis related fractures. This is true of Industrialised countries as well as of threshold countrie...
