  1. 1. Microsystems for Harsh Environments

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stefan Knaust; Lena Klintberg; Klas Hjort; Fredric Ericson; Samuel Marre; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microsystems; harsh environments; high pressures; high temperatures; supercritical microfluidics; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : When operating microsystems in harsh environments, many conventionally used techniques are limiting. Further, depending on if the demands arise from the environment or the conditions inside the system, different approaches have to be used. READ MORE

  2. 2. Industrial Application of Sulfur Concrete An Environment-friendly Construction Material

    University dissertation from Institutionen för arkitektur

    Author : Amon Raphael Makenya; [2001]
    Keywords : Sulfur binder; Chempruf modifyer; Sulfur Concrete SC ; Durability; SC market survey; SC Applications; Environment.;

    Abstract : Sulfur Concrete (SC) is a thermoplastic constructionmaterial, of mineral aggregates and modified sulfur as binder.Elemental sulfur has now a low smelting point (120oC) and appears in two solid allotropic forms,separated by considerable contraction. Hence, the need formodification to delay the transition. READ MORE

  3. 3. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments

    University dissertation from Institutionen för arkitektur

    Author : Elof Köhler; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectric; Thermoelectric harvester; harsh environment; piezoelectric harvester; supercapacitor; coupled harvester; Piezoelectric; Energy harvester;

    Abstract : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. READ MORE
