  1. 1. Simulations of drainage and phosphorus leaching with the ICECREAM model for 15 years at Mellby experimental field

    University essay from SLU/Dept. of Soil and Environment

    Author : Jian Liu; [2010]
    Keywords : drainage; phosphorus leaching; ; ICECREAM model; Mellby experimental field;

    Abstract : Phosphorus (P) losses from agricultural fields have been recognised as one of the mostimportant sources of P causing eutrophication in water bodies. Water transport in soil playsan important role in P leaching from drained fields. READ MORE

  3. 2. Behavior Modeling of a Digital Video Broadcasting System and the Evaluation of its Equalization Methods

    University essay from Datorteknik

    Author : Wang Jian; Xie Yan; [2010]
    Keywords : ATSC; Multipath; Channel Estimation; Channel Equalization; FEQ; Inter-Block Interference;

    Abstract : In this thesis, a single carrier ATSC DTV baseband transmitter, part of the receiver(including channel estimator and channel equalizer), were modeled. Since multi-pathinduced ISI (inter symbol interference) is the most significant impact on theperformance of single carrier DTV reception, modeling and implementation of singlecarrier channel estimator and channel equalizer have been the focus of the thesis.
