  1. 1. Arbetsresultat efter markberedning med en tvåhövdad hängande testbänk med inversfunktion

    University essay from SLU/School for Forest Management

    Author : Martin Andersson; [2018]
    Keywords : invers; högläggning; aggregat;

    Abstract : Today, inverting is performed mostly using crane-mounted devices. These devices must increase their productivity in order to become more cost-competitive. One way to increase productivity is to make a two-headed device that can prepare the soil using both inverting and mounding. READ MORE

  2. 2. Smart Hydroponics : Conceptual Design of Hydroponic Plant System for Home Environment

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Erik Földhazy; [2018]
    Keywords : Industrial Design Engineering; User Experience; Sustainability; Product Design; Human- Centered Design; Hydroponics; Teknisk Design; Användarupplevelse; Hållbarhet; Produktdesign; Human-Centered Design; Hydroponik;

    Abstract : Hydroponics is a method of cultivating plants without the use of soil. Soil acts as a growth medium which gives plants stability, provides nutrients and allows roots to be kept wet without drowning. In hydroponics the soil’s functions are replaced by synthesized methods. Stability comes from a substrate (i. READ MORE

  3. 3. Carbon budgets in northern Swedish Forests, 1800-2013

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

    Author : Gustav Stål; [2018]
    Keywords : climate change mitigation; northern Swedish forests; carbon dept; substitution; harvested wood products; klimatförändringar; norra Sveriges skogar; kolskuld; substitution; träprodukter;

    Abstract : Forests and forest management can mitigate increased carbon dioxide (CO2) concentrations in the atmosphere through sequestration of carbon and/or substitution. A major question has been whether it is better to use or conserve forests, with some claiming that European forests carry a huge carbon debt as a result of forestry. READ MORE

  4. 4. Low Power Wide Area Network (LPWAN) Technologies for Industrial IoT Applications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Nikolaos Tsavalos; Ahmad Abu Hashem; [2018]
    Keywords : iot sigfox nb-iot cat-m1 iiot industrial hms coverage capacity latency pycom lund malmo hurva; Technology and Engineering;

    Abstract : Industrial Internet of Things (IIoT) is part of the well-known IoT concept where a large number of devices need to be interconnected in order to collect and exchange data. Companies’ aim is not only to minimize cost during product design, operation and maintenance but also to enable remote monitoring on the efficiency of the devices-assets through the utilization of cloud services.

  5. 5. Improved Lightning Performance for 132 kV OHL

    University essay from Chalmers tekniska högskola/Institutionen för material- och tillverkningsteknik

    Author : Tomas Ingemarson; Johan Stelin; [2017]
    Keywords : Lightning performance; statistical insulation coordination; shield wire; portal tower; tower foot resistance; fault distribution; 132 kV.;

    Abstract : Lightning strokes to transmission lines causes a majority of the power quality issues that are so severe that sensitive industrial loads are disturbed. Historically Vattenfall concluded that it is too expensive to use shield wires for the 132 kV grid due to the high soil resistivity in Sweden. READ MORE
