Connode have developed a mesh radio solution based on 6LoWPAN, IPv6 over Low Powered Wireless Personal Area Network. By using this technology the communication unit on every meter is acting as both receiver and
Båtklubben i Kiviks hamn har länge upplevt problem med stora vågor i hamnbassängen. Denna studie ämnar att fastslå vilka vågförhållanden och fenomen som ger upphov till dessa problem, samt att föreslå åtgärder. En undersökning av vågklimatet utanför hamnen utförs med hjälp av en enkel modell, kallad SPM, som beräknar en tidsserie vågor utifrån meteorologisk och geografisk data. För att kartlägga vThe yacht club in Kivik marina has experienced problems with large waves in the harbour basin for a long time. This study aims to determine the wave conditions and phenomena that give rise to these problems, and to propose measures. An investigation of the wave climate outside the harbour is carried out using a simple model, called SPM, which calculates a time series of waves based on meteorologic
A recurring argument in scholarly literature is that the EU is suffering from a democratic deficit in which its institutional legitimacy is being questioned by the public. To remedy this issue and gain public legitimacy, the EU has over the last 20 years developed a public communications approach to engage citizens in European affairs and to create a European public sphere. However, the EU has not
An increasing number of companies are now publicly committing to becoming carbon neutral or achieving net-zero emissions. While most organisations will focus on preventative measures to reach their targets, climate compensation will also make up part of a company’s carbon management strategy. Initial reports indicate that corporate investments in forestry-related initiatives have significantly inc
This dissertation discusses aspects of the syntax of Övdalian, a variety spoken by ca. 2,500 people in the province of Dalecarlia in Sweden. Initially, an overview of the history and current status of the language of Älvdalen is given, and the focus of the dissertation is on certain syntactic phenomena that have been well studied from a comparative and diachronic perspective in other Scandinavian
The healthcare sector is one of the fastest growing economic sectors of today. The medical device domain is one part of that sector. An increasing part of functionality in medical devices and systems is implemented in software and many features should not be possible to implement without software. The use of medical software is an inherent risk to the patient and the outcome of a failure can vary
Background: Cerebral ischemia activates both the innate and the adaptive immune response, the latter being activated within days after the stroke onset and triggered by the recognition of foreign antigens. Methods: In this study we have investigated the phenotype of antigen presenting cells and the levels of associated major histocompatibility complex class II (MHC II) molecules in the postischemi
Background: Sleep disturbances are common among older people (>65 years). Further, long-term use of sedative-hypnotics in older people is associated with morbidity and mortality. However, older people represent a large span of life years, and few studies have included the oldest-old above 85 years. Aim: To investigate and compare sleep quality, use of hypnotics and sleeping habits in different age
Introduction: Fenestrated aortic stent-grafts are increasingly being used to treat patients with juxtarenal abdominal aortic aneurysms (AM). Sizing of these stent-grafts is critical to ensure success and requires detailed expert assessment of aortic morphology. At present little is known about how sizing of these stent-grafts varies between observers and the necessary tolerances involved to ensure
Background: Interferon beta-1a (IFNbeta-1a; Avonex) is effective for the treatment of relapsing MS; however, the optimal dose of IFNbeta-1a is not known. Objective: To determine whether IFNbeta-1a 60 mug IM once weekly is more effective than IFNbeta-1a 30 mug IM once weekly in reducing disability progression in relapsing MS. Methods: In a double-blind, parallel-group, dose-comparison study, 802 pa

How does the brain transform the 2-D light arrays in our eyes into a meaningful 3-D description of surfaces around us? What assumptions does the visual system make about the world when information is incomplete? And how are these assumptions computationally expressed in this perceptual reconstruction process? These questions, and other aspects of binocular depth perception are analysed from a theo
Popular Abstract in Swedish Hawaiianernas liv och historia har dokumenterats allt sedan första kontakten med västerländska äventyrsresanden i slutet av 1700-talet. I samband med amerikanska missionärers ankomst år 1820 introducerade och etablerade dessa missionärer en puritansk lära och kunskapsförmedling via det skrivna ordet. Mötena mellan de olika kulturerna har beskrivits som fredliga. Dock haThe life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri
BACKGROUND AND OBJECTIVES: Few studies have demonstrated that bacterial vaginosis (BV) is associated with sexual behavior risk factors similar to those for other sexually transmitted diseases. The objective of this study was to determine the prevalence of these factors in a multivariate analysis of data from women infected with BV and Chlamydia trachomatis, and noninfected control subjects. GOALS:
Interactions between light and matter is one way to study both particles whose small spatial sizes render them irresolvable to our eyes and events where the characteristic time scale is too short for conventional recording and measurement techniques. The advent of free electron lasers allow laser pulses of high intensity and small temporal duration such that ultra-fast dynamics in matter systems a
På järnvägsstationer passerar dagligen många människor som pendlar till och från arbete eller skola och ofta sker byter mellan olika transportmedel. Vid dessa byten behöver oskyddade trafikanter (fotgängare, cyklister och elsparkcyklister) ofta korsa en väg vid ett övergångsställe. Beroende på övergångsställets reglering uppstår olika beteenden och konflikter. Oväntade beteenden hos oskyddade trafAt railway stations many people pass daily commuting to and from work or school, often switching between different forms of transportation. During the change of transportation, the unprotected road users (pedestrians, cyclists, and e-scooters) might need to cross a road at a crosswalk. Depending on the form om regulation of the crosswalk different behaviors and conflicts occurs. Unexpected behavio
As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. But as more DG is installed, it can lead to issues in the DN such as overloading and overvoltage when production is
Cultural tourism and cultural heritage management, while distinct disciplines with differing foci, are also inherently intertwined. However, conflicts between the two often arise due to the diverse number of stakeholders and interests involved in either the travel industry or the conservation and protection of cultural heritage. Despite this, cultural tourism can greatly benefit the conservation o
Background: Mental health is a global public health issue. Mental health disorders can develop in anyone, but the prevalence is higher among refugees. Mental Health and Psychosocial Support (MHPSS), aims to improve mental health and is commonly applied among persons from conflict-afflicted settings such as, refugees. There are several studies demonstrating the effectiveness of MHPSS but there
