2. 1. 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

4. 2. 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

5. 3. Following the mevalonate pathway to bone heal alley

   Author : Björn Skoglund; Lars Nordsletten; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bone screws; coated materials; biocompatible; chemistry; diphosphonates; pharmacology; Equipment failure analysis methods; Femoral fractures; drug therapy; fracture fixation; instrumentation; Fracture fixation; fracture healing; drug effects; simvastatin; tibial fractures; physiopathologyial fractures; surgery; Pharmaceutical chemistry; Farmaceutisk kemi; Other veterinary medicine; Övrig veterinärmedicin;

   Abstract : The mevalonate pathway is an important biosynthetic pathway, found in all cells of virtually all known pro- as well as eukaryotic organisms. This thesis is an investigation into the use of two drugs, originally developed for different applications, but both affecting the mevalonate pathway, in to models of fracture repair. READ MORE

6. 4. Condition measuring and lifetime modelling of disconnectors, circuit breakers and other electrical power transmission equipment

   Author : Per Westerlund; Patrik Hilber; Tommie Lindquist; William Q Meeker; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reliability; maintenance; condition monitoring; disconnector; circuit breaker; Weibull distribution; prediction; risk analysis; decision making; beta distribution; Electrical Engineering; Elektro- och systemteknik;

   Abstract : The supply of electricity is important in modern society, so the outages of the electric grid should be few and short, especially for the transmission grid. A summary of the history of the Swedish electrical system is presented. The objective is to be able to plan the maintenance better by following the condition of the equipment. READ MORE

7. 5. Probabilistic Stability Analysis of Underground Mine Excavations

   Author : Musa Adebayo Idris; Tarcísio Celestino; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : The creation of underground mine excavation disturbs the original state of the rock mass surrounding the excavation which often leads to instability of the excavation. This poses a threat to the safety of personnel and equipment in and around such excavations. READ MORE
