Astronomernas främsta verktyg har alltid varit ljus. I många tusen år har vi observerat ljuset från stjärnorna med blotta ögat och noterat deras positioner på himlavalvet. Ett av de största genombrotten i astronomi var upptäckten att när ljuset bryts ner i ett spektrum med ett prisma eller ett gitter, och alla färger syns separat, syns det mörka linjer i spektrumet. Varje grundämne har sitt egna kObserving in the infrared has many benefits, such as seeing through the interstellar dust in the galaxy, easier use of adaptive optics, and better flux ratios for direct observations of exoplanets. Before the infrared spectral range can be utilised for highly accurate stellar spectroscopy there is a need for a better understanding of both stellar modelling and the atomic physics that go into formi

Advancements in today's technology has motivated invention of faster mobile communication systems. The fifth generation mobile network, 5G, is the latest version made by the third generation partnership project (3GPP) and expects to both increase connection speed and reduce latency, which eventually will make it applicable in supporting state-of-the art technologies such as virtual reality and

Syftet med studien var att förstå om och hur sångare har upplevt fysisk och emotionell påverkan av målbrottet och hur deras kunskap om målbrottet ser ut. Vidare var syftet att ta reda på hur utbildade och erfarna sångpedagoger förhåller sig till och arbetar med målbrottet i sin undervisning för att förstå vilka arbetssätt framtida sångpedagoger kan använda sig av. Bakgrunden till studien grundar sThis study aims to understand if and how singers experience voice change in a physical and emotional way and how much knowledge they have about their adolescent voice change. Further on the study also aims to understand how educated and experienced vocal teachers adapt and are working with adolescent voices and how their working methods can be used for other future vocal teachers. The background t

Syftet med denna studie var att göra en systematisk litteraturstudie genom att undersöka tio RCT-studier om traumarelaterad skam och PTSD. Syftet var att identifiera i vilken utsträckning KBT-behandlingar effektivt kan behandla skam relaterad till traumaincidenter, och även hur skam har behandlats i studier av traumabehandling. De undersökta studierna använde olika KBT-behandlingar och studerade oThe aim of this study was to make a systematic literature study by examine ten RCT studies regarding trauma-related shame and PTSD. The aim was to identify to what extent CBT-treatments would effectively treat shame arisen from trauma incidents, and also regarding how shame has been treated in studies of trauma treatment. The examined studies used different CBT-treatments and studied different pop

In our pursuit of carbon neutrality, drastic changes to generation and consumption of electricity will cause new and complex demands on the power grid and its operators. A cheap, promising, and under-exploited mitigation is real-time power grid topology optimization (RTTO). However, beyond the simplest action of line switching, the combinatorial and non-linear nature of RTTO has made all computati

Ägarlägenheter är idag en ovanlig bostadsform på den svenska bostadsmarknaden, och har ännu inte byggts i särskilt vid omfattning. Boendeformen infördes i svensk lagstiftning år 2009, vilket kan vara en av anledningarna till att den ännu inte har hunnit etableras i samhället. Utomlands är boendeformen välkänd, men i denna uppsats undersöks främst den svenska lagstiftningen gällande fastighetsbildnOwner-occupied flats are today an unusual form of housing on the Swedish housing market, and have not yet been built to a particularly large extent. The form of housing was introduced into Swedish legislation in 2009, which may be one of the reasons why it has not yet had time to establish itself in the society. Abroad, the form of housing is well known, but in this essay the Swedish legislation r

Examensarbetet jämför tre olika metoder för dimensionering av en spont. Syftet med arbetet är att utreda hur de valda beräkningsmetoderna inverkar på dimensionerande snittmoment och dimensionerande förankringskrafter samt att undersöka hur resultaten från de olika beräkningsmetoderna varierar vid ändring av ingående parametrar. De tre beräkningsmetoder som jämförs är den analytiska metoden från SThis master thesis compares three different methods for dimensioning a sheet pile wall. The purpose is to investigate how the chosen calculation methods affect dimensioning moments and anchoring forces in a sheet pile wall and to investigate how the results from the different calculation methods vary when changing the input parameters. The three calculation methods that are compared are the analy

Fältandaktsboken i dess olika utgåvor har som syfte att vara en del av den militära själavård som Försvarsmakten tillhandahåller. Själavården är i sin tur en del av Försvarsmaktens personalvård. Där många andra myndigheter och företag har personalvårdsavdelningar som gör insatser för att uppmuntra sina medarbetare samt stödja dem i svåra stunder så är Försvarsmaktens personalvård dessutom inriktad

A nebuliser is a drug delivery device administrating medication in the form of a mist inhaled into the lungs, and used to treat respiratory diseases or disorders. Daily sterilisation of the nebuliser is required to avoid bacterial growth, and to maintain a high functionality. The aim of the project is to investigate what an optimal design for a portable sterilisation method of VMT nebulisers could

Gender equality has been recognized as an important factor on the road to economic development. Smart Economics and Gender Mainstreaming are two gendered development discourses aiming to achieve economic development through reducing gender inequality. This study aims to assess to what extent these discourses have an impact on economic development. A difference-in-differences analysis is conducted

Risk is of large importance for financial institutions and there are many different measures that can be used. A popular one is value at risk (VaR), which is the maximum likely loss for a portfolio of financial assets. Different methods of estimating it has been suggested, one often described is the variance-covariance method. Here a method based on a generative model called generative adversarial

Environmental brand activism has become a strategy applied by many brands to engage and take a stand in the issue of climate change. The aim is to spur a debate and spark an interest and collective action among the consumers (Sarkar & Kotler, 2018). However, environmental brand activism has not created the same kind of engagement and debate as other forms of brand activism (Manfredi-Sánchez, 2

In a rapidly urbanising world, the importance of rural towns and villages is often forgotten. Many people see more opportunities for employment, social life and their children’s future in the big city, leaving smaller, rural places empty and abandoned. This process of rapid urbanisation can in the long run result in the loss of many valuable villages, along with their local community and the tradi

Brain computer interfaces (BCI) provide ways for the brain to communicate directly with a computer, and are today primarily used as an aid for people with severe movement impairing disorders. In this study a BCI feature extraction method using a combination of spatial filtering and time-frequency (TF) analysis is developed. The features are then classified using a convolutional neural network. A f

On the 23rd of April 2019, TENA made a bold decision to launch a game-changing product by addressing a taboo subject publicly. The Silhouette Noir product is a unique adult diaper that looks and feels like elegant black underwear. Since it is the first black underwear on the market designed for the purpose of empowering women with incontinence, TENA wanted to tackle the dilemma publicly. Therefore

Den här studien har som syfte att utreda om Sveriges kraftvärme kan bidra till ökad flexibel elproduktion och i så fall på vilket sätt. Detta undersöks genom att kombinera analys av tekniska, marknads- och regelverksmässiga förutsättningar för Sverige. Detta gjordes med inriktning på kraftvärmeverk i Skåne, exklusive egenproducenter av el samt industrikraftvärmeverk. Dessutom analyseras erfarenhetThis master thesis aims to investigate if and how Swedish Combined Heat and Power (CHP) plants can increase its flexibility in electricity production. This is examined through a combining analysis of technical, market-oriented and regulatory conditions for Swedish and primarily Skåne CHP plants, excluding autoproducers and industrial plants. Further, Danish CHP experiences are analysed and applied
