1. 1. Wireless Communication for Critical Control : Analysis and Experimental Validation

   Författare :Xiaolin Jiang; Carlo Fischione; Zhibo Pang; Ming Xiao; Preben Mogensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Wireless communications are an essential enabler of the Industry 4.0 vision, as they have the potentiality to be deployed in scenarios where the installation of cables is impractical. LÄS MER

3. 2. Moisture-induced stress and distortion of wood : A numerical and experimental study of wood's drying and long-term behaviour

   Författare :Sara Florisson; Sigurdur Ormarsson; Johan Vessby; Kent Persson; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analytical method; calibration; controlled climate; creep; distortion; experimental methodology; FEM; fibre orientation; mechano-sorption; moisture transport; natural climate; Norway spruce; numerical model; three-dimensional; timber beam; validation; wood; Byggteknik; Civil engineering; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : With the current advances made in three-dimensional modelling of wood, it is possible to provide an overall picture of moisture flow, and moisture-induced stress and deformations, whereas previously, experiments only provided local measurements. The main aim of the doctoral thesis is to investigate the possibilities of the developed three-dimensional numerical model to predict the behaviour of wood when simultaneously exposed to a mechanical load and a particular climate.

4. 3. Aerothermal Experimental Investigation of LPT-OGVs

   Författare :Borja Rojo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Experimental; Turbine Rear Structure; Aerodynamics; Wind Tunnel; CFD; Gas Turbine; Engine Exit Structure; Outlet Guide Vane; Heat transfer.; Turbine Exhaust Case; Turbine Rear Frame; Exit Guide Vane;

   Sammanfattning : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. LÄS MER

5. 4. Experimental Validation of a Phased Array Ultrasonic Testing Probe Model and Sound Field Optimization

   Författare :Xiangyu Lei; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phased array; Sound field optimization; Experiments; Validation;

   Sammanfattning : New manufacturing technologies are developed to facilitate flexible product designs and production processes. However, the quality of the final products should not be compromised, especially for safety prioritized industries, e.g. aerospace industry. LÄS MER
