  1. 1. Compact Ku-band Microwave Filters Realised using Suspended Integrated Stripline Technology

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Henrik Åkerberg; [2023]
    Keywords : Suspended Substrate Stripline; Microwave filter; Low Profile; Quasi-Planar; Bandpass Filter; Hängande-Substrat-Stripline; Mikrovågsfilter; Låg profil; Kvasi-planar; Bandpassfilter;

    Abstract : As the fifth generation of telecommunications is deployed, and the number of devices transmitting in the microwave bands grows, effective filtering technologies are becoming ever more important. When a filter is designed, some performance trade-offs have to be made, and one of them is the trade-off between filter size and electrical performance. READ MORE

  3. 2. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

    University essay from Umeå universitet/Institutionen för fysik

    Author : Sara Holmér; [2021]
    Keywords : ;

    Abstract : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

  4. 3. Evaluating abundance of deciduous trees in production forests along small stream : can Sweden meet current policy goals without intensive management

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Jessica Åström; [2020]
    Keywords : Riparian forests; small stream; strategic management objectives; deciduous; forest policy change;

    Abstract : Riparian zones are important for many ecological functions such as for providing shade to streams and leaf litter to instream organisms, as well as acting as filters for sediments and excess nutrients that are released during forestry operations. Riparian areas are also important for preservation of biodiversity. READ MORE

  5. 4. OPEN STORMWATER SYSTEMS FOR REDUCTION OF HEAVY METALS : AN EVALUATION OF COMMONLY USED DIMENSIONING METHODS

    University essay from Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Author : Johan Jönsson; [2018]
    Keywords : Stormwater; Heavy metals; Ponds; Filter strips; Wetlands;

    Abstract : In Östersund there are a few stormwater ponds and oil separation units   connected to the stormwater network, but mostly there is no systems for   filtration of stormwater before it is released into a nearby lake which acts   as Östersund’s source of drinking water. In the Industrial area in Lugnvik there   is an oil separation unit connected to the stormwater network but no other   means of filtration. READ MORE

  6. 5. Sequential phosphorus extraction using iron (hydr)oxide-impregnated filter paper strips

    University essay from SLU/Dept. of Soil and Environment

    Author : Jean Rene Marius Tuyishime; [2016]
    Keywords : phosphorus; Pi-filter strip; desorption; depletion; soil phosphorus tests;

    Abstract : Phosphorus (P) is an important element for crop production. A low concentration limits crop growth whereas the residual quantity after fertilization contributes to eutrophication of surface waters. A key to success in the soil P management is its accurate estimation and potential supply to the plant. READ MORE
