Energy poverty has been kept at bay in Sweden for the past decades owing to several beneficial circumstances. However, geopolitical pressure and an accelerating energy transition are changing the circumstances and exposing vulnerabilities to energy poverty in Sweden particularly connected to electricity price peaks. The circumstantial nature of the exposed risks for energy poverty motivates a conc
Recently the Intergovernmental Panel on Climate Change released their 6th Assessment reports which confirm that the impact of climate change is visible, e.g. through an increased weather volatility leading both to hotter drier weather and increased flooding in some regions globally. One clear example of this is the increased prevalence of wildfires in recent years and increasing wildfire potentialRecently the Intergovernmental Panel on Climate Change released their 6th Assessment reports which confirm that the impact of climate change is visible, e.g. through an increased weather volatility leading both to hotter drier weather and increased flooding in some regions globally.

Pilot på LTH med skåp för elcykelbatterier Under september 2024 sätts tre skåp för förvaring och laddning av elcykelbatterier upp på campus i samarbete mellan LU Byggnad, LTH och Akademiska Hus. Skåpen kommer att stå utanför E-huset, A-huset och Kemicentrum och kan användas av både medarbetare och studenter. Detta är en av flera lösningar som är på gång med anledning av förbudet att ta in elcykelb
Globally 884 million people depend on unsafe drinking water, of which 159 million depend on untreated surface water (WHO, 2017). In Tanzania 44% of the popula- tion lack access to safe drinking water (WaterAid, 2017). Women and children in the small city of Chonyonyo, in Karagwe district are walking several hours a day for contaminated drinking water. According to a study, carried out in Tanzani
Presently the telecom industry is going through a massive shift in technology. In the business to business environment regarding delivery and service of fixed telephony, the traditional circuit-switched PBX (private branch exchange) technology is successively replaced by a new Ip-based (Internet protocol) PBX technology. The new way of switching voice-calls doesn't demand a separate infrastruc
Many spatial audio applications, including active noise control, virtual reality, and the generation of individual sound zones, rely on an understanding of acoustic propagation. In room acoustics, which is the focus of this thesis,the sound field generated by a point source is typically modelled as a linear time-invariant system, described by its room impulse response (RIR). The RIR captures the r
Non-linear acoustic methods has shown increasing potential in the identication of damage in brittle materials such as concrete. Commonly, these methods focus on one or several resonance frequencies of the material and on the relative change in resonance frequency and attenuation with strain amplitude which has been shown to allow one to identify the extent of the material damage. However, current
Renewable energy pursuit and implementation are undoubtedly one of the most important steps in sustainable development across the globe. So far there are several developed high-income countries in the world, that have replaced their fossil fuel-powered electricity systems for renewable energy technologies, however, most of the world still relies on non-renewable energy sources. This research will
"At searching for lost point sources, it is important to use an optimal search strategy and an optimal methodology for spectrum data analysis. The purpose of this work is to evaluate a simple on-line method for locating lost point sources in the environment with carborne gamma spectrometry and study different strategies for detector geometries and speed of the car. The scope of this thesis
Introduction: Regional and global brain volumes are of great interest in many different research projects, not least in Alzheimer’s research. The purpose of this project is to optimize the MPRAGE sequence for automatic and repeatable segmentation of human brain tissue. The volume is calculated for the whole brain, white matter (WM), grey matter (GM) and cerebrospinal fluid (CSF). Materials and met
This work investigates crew opinions about manual intervention on board submarines and planned new solutions on the new submarine, the A26. The planned solutions include an unmanned aft and the installation of water mist instead of Halon 1301 as fire suppression system. Literature, survey and interviews were used to gather information. The crew routines and previous fire incidents were determined.
Abstract in Undetermined An alternative to the standard endurance/perdurance accounts of persistence has recently been developed: the stage theory (Sider, 2001; Hawley, 2001). According to this theory, a persisting object is identical with an instantaneous stage (temporal part). On the basis of Leibniz’s Law, I argue that stage theorists either have to deny the alleged identity (i.e. give up their
It is sometimes said that modern politics has lost track of ideology and vision - that personal charisma and expertise is rewarded more than firm beliefs and connections with an organised movement. In their book Technopopulism: the New Logic of Democratic Politics, Christopher J. Bickerton and Carlo Invernizzi Accetti go beyond such suspicions. Their main argument is that the organisational politi
Global environmental issues concern a growing number of people and businesses are expected to communicate efforts towards environmental sustainability. Due to the controversial nature of its business practices and contribution to environmental problems, the oil industry holds a poor reputation and is considered to have a special need to communicate their efforts towards more sustainable business p
