1. Theoretical Analysis of Sewer Pipe Inspections andOptimization of CCTV Inspection for EffectiveMaintenance: Moving from Reactive to Proactive : A Guide Towards Selecting and Implementing Advanced Technologies forEnhanced Sewage Infrastructure Management
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : The wastewater- and sewage distribution network is a critical aspect for maintaining a socialandenvironmental well-being. However, in the latest time, many failures (such as leakages) haveoccurred due to poor conditions in the wastewater-infrastructure, causing several consequencessuch as damage to the environment or pose health hazards to the public.

2. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. LÄS MER
3. Modeling of a Hydraulic Rock Drill for Condition Monitoring
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : This thesis aims to investigate the possibility of using a mathematical model to detect several common faults in a hydraulic rock drill. To this end, a parameterized state space model of the hydraulic drill, which simulate its behavior, is created. LÄS MER
4. A Standardized Approach for Water Reduction Measures in Industrial Companies : Organizational Constraints and Effects on Economy and Environment
Master-uppsats, Linköpings universitet/EnergisystemSammanfattning : The access of water globally is becoming more strained, why the focus on industrial water use is increasing. The present study examined how industries should approach water efficiency projects, what organizational constraints that should be addressed, and what effects water saving measures have on economic costs, environmental impact and influence from water related risks.

5. Identification and evaluation of internal leakages of a BFB Boiler integrated within a pulp and paper mill.
Master-uppsats, Högskolan i Gävle/EnergisystemSammanfattning : Alternative fuels like biomass have become really popular in the last decades as a substitute to fossil fuels. One of the most used technologies in Sweden for the obtention of the energy from the biomass is its direct combustion in a boiler. LÄS MER
