  1. 36. Weight Optimization of Radar Shelter using Design of Experiment

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nils Jonnerby; [2018]
    Keywords : Weight optimization; Design of experiment;

    Abstract : This master thesis covers the subject of Design of Experiment which is a method of executing experiments or simulations in designed and well planned approaches. The method has been investigated and implemented at a Radar shelter at the Giraffe A4 Radar truck developed by SAAB AB. READ MORE

  3. 37. Robust Design and Analysis of Automotive Collision Avoidance

    University essay from Göteborgs universitet/Institutionen för matematiska vetenskaper

    Author : Anders Sjöberg; [2017-02-10]
    Keywords : Simulation-based optimization; response surface methodology; radial basis functions; multi-objective optimization; Pareto optimal solutions; trigger edge; tunable parameters; false intervention; robustness; positive and negative performance scenarios.;

    Abstract : Automotive collision avoidance systems help the driver to avoid or mitigate a collision. The main objective of this project is to find a methodology to improve the performance of Volvo's automotive collision avoidance system by optimizing its configurable parameters. READ MORE

  5. 39. Comparing the diffusive gradient in thin film (DGT) method with water and ammonium-acetate-lactate for P extraction and extractable P required for maximum cereal yield using long-term field experiments

    University essay from SLU/Dept. of Soil and Environment

    Author : Cornelia Mesmer; [2017]
    Keywords : fertilization; plant-availability; agriculture; diffusion; phosphorus efficiency;

    Abstract : Using more phosphorus fertilizer than needed generates unnecessary costs for farmers and can lead to eutrophication of surface waters. Up to now, most country-specific soil tests to determine P plant-availability use chemical extractions that often extract P from non-plant available pools and are not suitable for all soil types.

  6. 40. Landscape factors related to performance of in-situ sensors for prediction of total phosphorus : a statistical analysis of data from 194 streams in Sweden

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Cham Hoang; [2017]
    Keywords : surface water monitoring; surrogate parameters; total Phosphorous; turbidity; catchment; land-use; soil type;

    Abstract : Accurate monitoring data of phosphorus concentrations in the water will benefit the evaluation of measures taken to reduce the problems of eutrophication. Today, the quantification of phosphorus loads from diffuse sources involves large uncertainties. READ MORE
