  4. 13. ON DVB-H RADIO FREQUENCY PLANNING: : ADJUSTMENT OF A PROPAGATION MODEL THROUGH MEASUREMENT CAMPAIGN RESULTS

    University essay from Institutionen för teknik och byggd miljö

    Author : Gema Roig; [2008]
    Keywords : Propagation; model; adjustment; planning; radioplanning;

    Abstract : The present Master Thesis analyzes the DVB-H radio Frequency Network Planning problematic, studying the influence of a propagation model used in the calculation of network coverage. In this way, the aim of this work is the design of a procedure and algorithm to adjust a propagation model considering measurement campaigns performed in different environments (dense-urban, urban, sub-urban and rural).

  5. 14. Mjölkningsfrekvensens inverkan på mjölkfettets kvalitet

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Anna-Karin Båvius; [2006]
    Keywords : mjölkkor; mjölkkvalitet; mjölkningsfrekvens;

    Abstract : The milk production has developed rapidly the last years. The milk production per cow is increasing and the production units are larger with an increasing number of animals and a decreasing number of workers. Many milk producers invest in automatic milking systems (AM) to meet this change. READ MORE
