Brandgasventilation i stora lokaler

The aim of this study is to investigate parameters that influence the effectiveness of the two main methods of smoke management, thermal and mechanical smoke ventilation, to determine when one of these methods is favorable to the other. To accomplish this simple hand calculations as well as more advanced computer programs, such as FDS and Argos, were used. The study was conducted in collaboration

Inelastic LIDAR for Monitoring Aquatic Fauna

Det här examensarbetet fokuserar på att designa och konstruera en ny typ av instrument för att studera plankton och den miljö de lever i. Arbetet utnyttjar de framsteg som gjorts inom små diod-lasrar och små kamerasensorer tillsammans med innovativ optik för att konstruera ett kompakt och relativt billigt instrument som på avstånd kan upptäcka individuella plankton på flera djup samtidigt och på saThis thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases. Here we extend the concept to inelastic hyperspectral ranging ca

Current ripple simulation of the electric system of an electric bus

With effect of global warming and climate change the electrification of vehicles enables a more sustainable and environmentally friendly alternative to conventional vehicles as it reduces toxic emissions and overall energy consumption. Different extents of electrification is today used. Hybrid and electric vehicles are two examples. Tools to simplify the design of electric vehicles are of value to

Reglering av hållbarhetsredovisning - En studie om energibolags kommunikation med intressenterna

Problem: Hållbarhetsredovisning har alltid varit fri från formkrav vilket har inneburit stor flexibilitet för företag både sett till om hållbarhets- rapporter ska upprättas och vilket innehåll dessa ska ha. Då lagreglering blir gällande från och med räkenskapsåret 2017, som gör det tvingande för större företag att hållbarhetsredo- visa, frågar vi oss hur detta lagkrav kan komma att påverka den inf

Analys av aktörsnätverket involverat i hanteringen av översvämningsrisk i Göteborg

Klimatförändringar medför ökad risk för översvämningar och kustnära Göteborg är särskilt utsatt. Aktörerna som arbetar med att hantera översvämningsrisker bildar ett socialt nätverk och hur det ser ut kan få stora effekter för riskhantering i samhällsplaneringsprocessen. Via examensarbetet har det nu gjorts försök att kartlägga och analysera effekterna av detta nätverk. Förändringar i klimatet orDue to today’s climate changes, the risk of flooding is increasing, both caused by rising sea levels and as a consequence of heavy rainfall. Urban environments are largely consisting of impermeable surfaces, unable to permeate large amounts of water in the event of a flooding. In the scope of this work, the aim has been to map the social network of actors involved in flood management in Gothenburg

Optimization of methods to grow spinach hydroponically in the presence of antagonists and their activity against Escherichia coli

Fruits and leafy vegetables are the major target of pathogenic E.coli outbreaks. Usually soil and other contaminants present in the land provides easy pathway for pathogenic bacteria to enter the plant body. Later upon consumption of such infected food lead to various health problems. To overcome such outbreaks, during our study one of the leafy vegetable spinach was used as a medium to understand

New Concepts for PTR Functionality in Fixed Domes

This report describes the design and development of new concepts for pan, tilt and rotate functionality in fixed domes at Axis Communications. The aim of the master’s thesis was to generate a concept that are smaller and less expensive compared to the solutions today. Remote pan, tilt and rotate is a unique feature which makes it possible to remotely control a camera during installation and redire
