Simulating complex physical systems often requires solving systems of nonlinear algebraic equations. One of the most frequently used numerical methods to solve systems of nonlinear equations is Newton's method with its advantage of quadratic local convergence. However, Newton's method does not guarantee global convergence. This raises the need for combining Newton's method with a globa
Bakgrund: Hälso- och sjukvårdspersonal har en skyldighet att främja amning och informera samhället om amningens fördelar. Sedan 2010 har amningsfrekvensen avtagit under barns första sex levnadsmånader och det är av största vikt att undersöka vilka faktorer som är bakomliggande till den nedåtgående amningstrenden. Syfte: Studiens syftet var att jämföra förstföderskors och omföderskors erfarenheter
Recent policy developments on the global, regional and national levels have materialised strategic goals for building resilience. Implementing resilience fundamentally requires operationalising the concept in order to make it measurable. This thesis scoped for professional resilience measurement methodologies across grey literature and analysed their organisational purposes and specifics of measur
The world today faces many different environmental problems, which has a negative effect. These are both global, regional and local, which means that they affect all people. To be able to overcome this and be able to promote a long-term sustainability, it is essential that all contribute and take responsibility for it. An example of doing this is to get more people to commute rather than using the
Abstrakt Syfte: Syftet med studien var att undersöka samkönade föräldrars upplevelser av barnhälsovården. Bakgrund: Samkönat föräldraskap ökar runt om i världen, men trots det upplever många samkönade föräldrar att hälso- och sjukvården är heteronormativ och inte ger utrymme för alternativa familjekonstellationer. Många blir bemötta med fördomar och heteronormativa antaganden, vilket ger en känsl
Physical activities such as running have previously been proven to be positive on the health of individuals who partake in such activities. Further studies have separately analyzed the positive benefits of natural environments, such as forests, and positive effects of music on runners. This study evaluates how the presence or absence of such natural environments with and without musical stimuli ef
Stora skärmar med stöd för multitouch börjar användas i många olika sammanhang, som till exempel museum eller skolor. Participativ design är exempel på en användbar metod för att inkludera medborgare i stadsplanering. Ett gränssnitt för participativ design på touchskärmar behöver vara väldesignat och intuitivt. För att utforska hur ett sådant gränssnitt kan se ut användes en iterativ användarcentr
In this study, vacuum impregnation (VI) was used to investigate the effect of different solutions: sucrose 21 % (w/v), calcium lactate 1 % (w/v), ascorbic acid 0.1 % (w/v), and GABA 0.075 % (w/v) on atmospheric composition, color, and shelf life of packed baby spinach leaves. VI was performed at two different temperatures: 21 C and 7.5 C. The packed, impregnated leaves were stored for 8 days at 21
This report contains a master thesis by Stina Leghammar that was developed at Axis Communication in Lund Sweden. The thesis contains a development and design process of a modular sensor unit that will be mounted on light poles in urban areas. The sensors that will be included in the unit is a camera, a radar, a thermometer, an Plasmonic Air Quality Sensor and a microphone, all to detect and get da
This study focus on influence of different drying and annealing conditions on the mechanical properties and film formation of the produced paint which is based on a novel hydroplasticized polymer dispersion. Two different coalescing agents with different polarity and a neat sample with two different thicknesses were used in order to study the influence of coalescing agent’s polarity, thickness and
I det här arbetet behandlas invånardialog på det sociala mediet Facebook. Jag har genomfört en studie av hur Helsingborgs stad använder sin Facebooksida för att föra en dialog med invånarna samt hur denna dialog ser ut i praktiken. Genom att göra en kvalitativ intervju med officiella representanter för Helsingborgs stad, en kvalitativ innehållsanalys av dialogen på sidan och granska styrdokument hIn this study I have adressed the topic of citizen dialogue on the social network Facebook. I have conducted a study of how the city of Helsingborg use their Facebook page to communicate with the citizens and how they relate to the different rules, guidelines and policies that exist about dialogue and communication with the citizens on social media. The result of the study has shown that the city
This master thesis consists of two parts, which both deal with NMR studies of the carbohydrate-binding domain of the protein galectin-3 (Gal3C). In the first part, 19F relaxation of two difluorinated diastereomeric ligands bound to Gal3C was analyzed with the model-free approach to extract information about the dynamics. The second part reports the assignments of the backbone amide 1H/15N resonanc
The thesis explores efficient implementation strategies for the European Spallation Source (ESS) linear accelerator simulator. The target simulator needs to run at real time, requires high computation accuracy, and should be scalable for high density beam scenarios. The high data processing, communication, and storage requirements due to a large data set, along with a strict accuracy requirement,
Many locations in Indonesia such as small islands and remote villages on the main islands are not connected to the main electricity grid, and may never be as they are too remote for grid extensions to be economically justifiable. Therefore, many either do not have electricity or are dependent on expensive diesel transports to fuel their stand alone, diesel powered mini-grids. Using a hybrid renewa
Many bird species living in farmland habitats have suffered severe declines in recent years. This fact has been object to many studies and the reasons for the decline are many, but it all comes down to effects of our shift to a more effective farmland management. We use the land in a more intense way than before. The use of chemicals has effect both on the birds and their food resources. A more ho
Each year millions of people receive emergency relief items from humanitarian organizations following disasters and crises. While significant time and resources have been invested in identifying the needs of affected populations and how to address those needs, significantly less focus has been given to environmental impacts of these response operations. These impacts can result in substantial nega
The fashion industry is a significant contributor to global environmental and social issues. But as a system, it is composed of different stakeholders that can work together to make a change. One of those actors involved are small fashion labels, which according to the European Commission, account for more than 90% of the workforce and produce almost 60% of the value within the textile industry (2
Humanitarian organizations transitioning from a service provider (SP) to a capacity strengthener (CS) in countries where there is political stability and economic growth presents a set of opportunities and challenges. Despite this there has been limited research studies that have been conducted on the transition of humanitarian organizations in this context. The overall objective of this research
Begreppet genre är centralt inom musikvärlden och inom musikundervisning. Således är detta ett begrepp vi behöver förhålla oss till. Syftet med studien är att ta reda på vilken funktion genre har i sångundervisningen och hur begreppet kan behandlas. Genre har en tydlig plats i styrdokumenten för sång och instrumentalundervisningen på det estetiska programmet. Därför är detta en intervjustudie med
As interest in social vulnerability to hazards grows, more indices are formulated for identifying and mapping population groups that may experience differential consequences from natural hazards. However, less attention has been given to the underlying choices researchers make when creating these indices. With the aim to contribute to understanding the issues surrounding social vulnerability indic
