  2. 11. Applanation Resonance Tonometry for Intraocular Pressure Measurement

    Author : Per Hallberg; Olof A. Lindahl; Anders Eklund; Christina Lindén; Per Ask; Umeå universitet; []
    Keywords : Physics; Resonance; applanation; tonometry; glaucoma; Goldmann; biomechanical; Intraocular; ART; Fysik; fysik; Physics;

    Abstract : Elevated intraocular pressure (IOP) is one of the major risk factors for glaucoma. Since glaucoma is a leading cause of blindness, reliable methods for measuring the IOP are important. This doctoral dissertation presents a new method, applanation resonance tonometry (ART), for measurement of IOP. READ MORE

  4. 12. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis

    Author : Marcus Hedegärd; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hysteresis modelling; adaptive hysteresis compensation; hysteresis compensation; magnetoelastic torque sensor; Preisach model; generalized Prandtl-Ishlinskii model; cylinder pressure estimation; torque estimation;

    Abstract : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. READ MORE

  5. 13. Novel Microsystem Techniques for Liquid Manipulation and Pressure Sensing

    Author : Jessica Melin; Göran Stemme; Sabeth Verpoorte; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; microsystem technology; pressure sensing; liquid manipulation; liquid control; micromixing; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : Scaling down operations and functions into the fascinating micro world not only improve performance, lower costs, and enable easier integration, but also opens the door to new functionalities. This truly multidisciplinary thesis presents novel solutions to current and relevant challenges in the areas of 1) on-chip liquid manipulation which has applications in micro total analysis systems, medical diagnostics, and drug discovery and 2) pressure sensing which has an established market in the automotive and industrial processes industry.

  6. 14. A Case-Based Reasoning System for the Diagnosis of Individual Sensitivity to Stress in Psychophysiology

    Author : Shahina Begum; Peter Funk; Helena Lindgren; Mälardalens högskola; []
    Keywords : Artificial Intelligence; Case-based reasoning; Sensor; Signals; Stress; Diagnosis; Computer-based system; TECHNOLOGY; TEKNIKVETENSKAP; Datavetenskap; Computer Science;

    Abstract : Increased stress is a continuing problem in our present world. Especiallynegative stress could cause serious health problems if it remainsundiagnosed/misdiagnosed and untreated. In the stress medicine, clinicians’measure blood pressure, ECG, finger temperature and breathing rate during anumber of exercises to diagnose stress-related disorders. READ MORE

  7. 15. Materials Design for the Improvement of SiC Field Effect Gas Sensor performance in High Temperature Process Control applications

    Author : Lida Khajavizadeh; Mike Andersson; Fredrik Eriksson; Krisztian Kordas; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Following growing concerns about the effect these last decades of accelerating energy consumption, escalating use of natural (not the least fossil) resources, and waste generation has had on earth’s climate, human health, and the environment, industry is facing mounting pressure to increase the energy-, resource-, and cost-efficiency of both processes and products while drastically reducing pollutant emissions. In response, industry is, besides increasing their utilization of renewable energy and introducing new bio-based products, taking advantage of the rapid development in 5G technology and associated wireless interconnectivity to move towards full automation of production processes and facilities.
