2. 1. Antibacterial Surfaces for Biomedical Applications

   Author : Saba Atefyekta; Chalmers tekniska högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; contact killing surfaces; antibiotic delivery; Antibacterial surfaces; Infection; mesoporous titania; Elastin-like polypeptides; antimicrobial peptides;

   Abstract : Medical devices such as orthopedic implants are intended to serve for improved quality of life. However, clinical success cannot be taken for granted and the most common reason for failure is due to biomaterials associated infection (BAI). READ MORE

4. 2. Causes and treatment of chronic respiratory failure : experience of a national register

   Author : Torbjörn Gustafson; Kerstin Ström; Karl Franklin; Kjell Torén; Kurt Boman; Leif Bjermer; Umeå universitet; []
   Keywords : Internal medicine; Invärtesmedicin; chronic obstructive pulmonary disease; pulmonary fibrosis; kyphoscoliosis; respiratory failure; sex; smoking; occupation; survival; long-term oxygen therapy; mechanical ventilation; lungmedicin; Lung Medicine;

   Abstract : Long-term oxygen therapy (LTOT) or home mechanical ventilation (HMV) can improve survival time in chronic respiratory failure. A national quality register could be an aid to identifying risk markers and optimizing therapy for respiratory failure. READ MORE

5. 3. Acoustic and afterload evaluation of left ventricular assist devices

   Author : Per Sundbom; Henrik Casimir Ahn; Laila Hübbert; Fredrik Gustafsson; Daniel M. G. Karlsson; Michael Broomé; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Afterload; Electronic stethoscope; Flow; HeartMate II; HeartMate 3; iOS-devices; Sound Analysis;

   Abstract : Background: Heart Failure is a serious condition with consequences not only for the individual patient but also for the society with a 5-year mortality rate of 45-60%, and a substantial economic burden. The estimated prevalence in Sweden is 2.2% and the age adjusted prevalence increases with higher age. READ MORE

6. 4. Enhancing Machine Failure Detection with Artificial Intelligence and sound Analysis

   Author : Thanh Tran; Jan Lundgren; Sebastian Bader; Domenico Capriglione; Mittuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Failure Detection; Machine Learning; Deep Learning; Sound Signal Processing; Audio Augmentation;

   Abstract : The detection of damage or abnormal behavior in machines is critical in industry, as it allows faulty components to be detected and repaired as early as possible, reducing downtime and minimizing operating and personnel costs. However, manual detection of machine fault sounds is economically inefficient and labor-intensive. READ MORE

7. 5. On reliability modelling of ageing equipment in electric power systems with regard to the effect of maintenance

   Author : Tommie Lindquist; Prof. Roland Eriksson; Dr. Lina Bertling; Docent Carl-Ejnar Sölver; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical power technology; Maintenance; reliability modelling; electrical power systems; ageing; failure mechanisms; Elkraftteknik; Electric power engineering; Elkraftteknik;

   Abstract : Power system maintenance optimisation involves obtaining the minimum total costs, including preventive and corrective maintenance costs and the cost of failures for both supplier and customer. To calculate the cost of failure, information is needed about the equipment reliability characteristics. READ MORE
