Broadband services require data rates that can only be achieved by using relatively high spectrum frequencies. At such high frequencies, the DSL (Digital Subscriber Line) signal is more susceptible to external noise sources, such as radio frequency interference and impulsive noise. This paper aims to characterize how the impulsive noise impacts on services and applications for a broadband system u
Popular Abstract in Swedish Syftet med denna avhandling är att skapa en bättre förståelse för vilken betydelse institutioner har för innovationsprocesser inom regionala innovationssystem. Den fokuserar särskilt på hur olika typer av institutioner på skilda geografiska nivåer samspelar; hur institutionell påverkan förändras i samband med att innovationsprocesser utvecklas över tid; samt vilka möjliEconomic geographers have long been intrigued by the role of institutions in innovation processes. It has been argued that differences in institutions are among the factors explaining the uneven innovative capacity across and within countries. The regional innovation system approach highlights the interrelationships of firms, universities, governmental authorities and other organizations, as well
Interactions between physical bodies constantly affect their properties. This thesis presents a theoretical study on the effects of interaction in few-body nanowire quantum dots. The focus is to a large extent on a phenomenon called Wigner localization, and how this, as well as other interaction effects, can be identified in an experiment by transport spectroscopy and by thermopower measurements.
This dissertation, based on six included papers, theoretically investigates properties of quantum few-particle systems. An overview of related experimental research - ultra-cold trapped dilute gases, and electrons in quantum dots - is given, followed by a description of some of the studied many-particle phenomena - Bose-Einstein condensation, quantized vortices, Wigner localization and the Tonks-G
The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years
Since the Industrial Revolution, human activity has driven major changes in the global climate through increased greenhouse gas emissions. To address this, the EU has introduced several regulatory instruments, including the CSRD and the accompanying ESRS, which require companies to report on environmental and social impacts, risks, and opportunities. As part of these obligations, companies are req
Environmental protection supervision is an important instrument for limiting and controlling the negative effects that environmentally hazardous activities can have on human health and the envi-ronment. Fuel facilities (“gas stations”) are one of these hazardous activities, supervised by envi-ronmental protection inspectors at the municipal level. To ensure legal compliance, inspectors use tools s
Sweden has long been seen as a leader in environmental policy. However, after the reorganization of the Swedish Ministry of the Environment in 2023, concerns have been raised about how this change affects the country’s climate work. This study investigates how the merger of the Ministry of Climate with the Ministry of Enterprise has influenced the political priorities between renewable energy and
Global biodiversity is declining, which threatens ecosystems as well as essen-tial ecosystem services. The corporate sector is an important part of the solu-tion. Companies covered by the Corporate Sustainability Reporting Directive (CSRD) are required to disclose their impacts on biodiversity according to the European Sustainability Reporting Standard (ESRS) E4 if their impacts are determined to
We are at a critical point where the carbon emissions worldwide must cease. One way to do so is to switch to renewable energy and become less dependent on fossil fuels. Solar power is an energy source which can be expanded rather quickly, and has become more common in the past years. The issue with large scale solar power plants is that they take up a lot of space, which leads to conflict of inter
Per- and polyfluoroalkyl substances (PFAS) are a group of highly persistent synthetic chemicals that have raised growing concern due to their widespread presence in the environment and potential health effects. This study focuses on Lake Bolmen, one of southern Sweden’s most important sources of drinking water, and investigates how PFAS enter and accumulate in the lake. A total of 23 PFAS compound
The public sector is responsible for 28 percent of the average Swedish citizen’s consumption-based greenhouse gas emissions (GHGe). Looking at purchasing categories with the highest GHGe, consumables – products like paper and single use items – play a significant role. The first step in becoming more circular and reducing waste is often to completely refrain from purchases when possible. However,
One third of the produced food for human consumption is wasted throughout the sup-ply chain. Given that 45% of the Earth's habitable land is classified as agricultural land, of which 16% is used for crop production, this situation is unsustainable. Food packaging could be one of the solutions to reduce food waste. Smart packaging, which includes active and intelligent packaging, is an innovati
IMPORTANCE: Human papillomavirus (HPV)-related cancers cause substantial morbidity and mortality. People with HIV (PWH) and solid organ transplant recipients (SOTRs) are at heightened risk due to impaired immune function, but direct comparisons of these groups within the same population are limited; understanding the relative risk and contributing factors is essential for targeted prevention and s
AimsTo evaluate the association between diabetes and four peripheral nerve entrapment syndromes: carpal tunnel syndrome (CTS), ulnar nerve entrapment (UNE), radial nerve entrapment (RNE), and tarsal tunnel syndrome (TTS).MethodsThis retrospective cohort study used the Merative™ MarketScan® Commercial Database (2007–2023). Adults ≥18 years were classified as having diabetes or serving as controls.
We aimed to investigate socioeconomic differences between sexes and the influence on outcome following surgery for carpal tunnel syndrome (CTS) or ulnar nerve entrapment (UNE) at the elbow. Patients with CTS (n = 9000) or UNE (n = 1266) registered in the Swedish National Register for Hand Surgery (HAKIR) 2010–2016 were included and evaluated using QuickDASH 12 months postoperatively. Statistics Sw
