  • An Introduction to 3G Networks Introduction What exactly are 3G networks? 3G is short for Third Generation (Mobile System). Here is a quick run-down: † 1G, or first generation systems, were analogue and offered only a voice service – each country used a different system, in the UK TACS (Total Access Communications System) was introduced in 1980. 1G systems were not spectrally efficient, were very insecure against eavesdroppers, and offered no roaming possibilities (no use on holidays abroad.)....

  • The objective of this work was to support the design of mechatronic systems by the use of simulations. This raises the question of what exactly is mechatronics. Current definitions describe mechatronics as an interaction between electronics, mechanics and information technology, see Isermann [164] or Wallaschek [421]. It makes no difference here whether we are talking about macromechanics or micromechanics.In the former case we speak of mechatronics, in the latter of micromechatronics or microelectromechanical systems (MEMS)....

  • A query expresses in a high-level language like SQL must first be scanned, parsed, and validated. • Once the above steps are completed, an internal representation of the query is created. Typically this is either a tree or graph structure, called a query tree or query graph. • Using the query tree or query graph the RDBMS must devise an execution strategy for retrieving the results from the internal files. • For all but the most simple queries, several different execution strategies are possible. The process of choosing a suitable execution strategy is called query optimization....
