You have already acquired basic Kiswahili grammar and vocabulary and would like to deepen both through exercises? Then this exercise book is just the right thing for you. It allows you to practise grammar and vocabulary step by step and to consolidate what you have learned. As the first volume of the series 'Kiswahili Grammar and Vocabulary Training', you will find exercises for the following units: 1. Pronunciation 2. Verbs 3. The simple imperative 4. Greetings and farewells 5. Personal pronouns 6.1 Present 'to be' 6.2. Negate 'to be' 7. Introducing oneself 8. Nominal classes 1 (ki/vi and m/wa) 9. Genitive construction 10. Present 'to have' 11. Sentence formation with subject and predicate 12. Possessive pronouns The exercise book is specially designed for independent training. PART 1 provides you with varied exercises on grammar, vocabulary and phrases. To enable you to check your learning, in PART 2 the solutions to the exercises are also provided.

Gegenstand dieser Arbeit ist eine systematische Erforschung des Zerspanverhaltens von faserverstärkten Keramiken mit unbeschichteten Fasern in einer porösen Aluminiumoxid-Matrix bei der Schleifbearbeitung in Abhängigkeit von der Faserorientierung bezogen auf die Schleifrichtung, dem Matrixtyp, dem Fasertyp und ausgewählten Schleifprozessparametern. Im Rahmen dessen werden die Ursache-Wirkungsbeziehungen, die zu den Zerspanmechanismen führen, vor dem Hintergrund der Werkstoffstruktur diskutiert.

This thesis studies the application of physics-based via models for an efficient modeling of large via arrays in multilayer PCBs. Three main aspects are addressed: the study and improvement of the modeling accuracy, the study and improvement of the model efficiency, and the application of the model in a systematic evaluation of via array design alternatives for high speed links. With regard to the modeling accuracy, the application of an improved local field model is identified as a suitable way to improve the model accuracy for the simulation of via arrays, especially at frequencies above 20 GHz. With the improved model, an accurate simulation of via arrays with a pitch of 60 mil or larger becomes possible in the frequency range up to 50 GHz. Improvements with regard to the model efficiency lead to a reduction of calculation times which allows to carry out fast design explorations for smaller via arrays on a standard PC. Finally, an approach for a systematic design evaluation is presented which integrates the advantages of the efficient physics-based via model in a larger concept. With the approach, a quantitative comparison of design alternatives becomes possible that takes into account the impact of design changes on both signal integrity and energy efficiency for the complete system.
