Indonesia has implemented national policies and legislations to encourage biofuel production as means to achieve energy security and self-sufficiency and to reduce reliance of fossil fuel reserves. However, there is still no clear road-map for the socio-technological transition. While acknowledging economic impediments, this case study investigates social and political obstacles to bioethanol prod

The memory is by far one of the brain’s most important and fundamental functions, but perhaps also one of the most unreliable. In order for information to be retained in memory, the brain performs, in a few milliseconds, an outstandingly complex process that is also very sensitive to external disturbances. With the information technology available today, it is easy to be distracted by redundant in

En forskargrupp vid partikelacceleratorn Large Hadron Collider (LHC) har nyligen visat att för en viss mätning så stämmer inte data från experiment överens med resultat från datorsimuleringar. Mätningen som gjordes var en undersökning av vinkelrelationer mellan de partiklar som bildas när andra partiklar kollideras vid väldigt hög energi, vilket innebär en hastighet väldigt nära ljusets. De partiAn analysis of two-particle angular correlations was recently performed on measurements taken from pp collisions at $\sqrt{s}$ = 7 TeV by ALICE at the LHC. The correlations for mesons are in good agreement with simulations performed in Monte Carlo event generators such as PYTHIA and PHOJET, but there is a significant difference for baryons. We here investigate particle production mechanisms in PYT

Energisystemsmodellering med fokus på den svenska vattenkraftens förmåga att balansera en ökad andel vind- och solelproduktion Det pågår idag en global omställning av elsystemet, från fossila till förnybara energikällor. Den nya elproduktionen väntas till stor del utgöras av variabel produktion, vilket medför nya utmaningar för elsystemet. I examensarbetet utvecklas en modell för att undersöka huThis thesis considers the representation of intermittent and flexible power production in long-term energy system models, and more specifically at the Swedish hydropower's capability of balancing the variations from increased shares of power from intermittent energy sources. The thesis aims to investigate how a present national TIMES model can be improved to better capture the technical, physi

An adaptive control system is proposed for an unknown integrator process with unknown dead-time. The process dead-time and gain are estimated simultaneously using an extended regression model and recursive least-squares estimation. The parameter estimates are used to scale the actuator signal, transforming the unknown process into a known reference process, while the dead-time estimate provides de

Wide-angle distance measurements are needed for positioning with multilateration when there is no information about in which direction objects of interest are located. Several transmitters of varying kinds were evaluated in a data-driven way using a 6 DOF robot actuator. A wide-angle (±98 degrees) distance measurement system us- ing ultrasound was developed. The resulting solution was integrated i

Vår målsättning är att skapa en sakral plats i en modern ceremonibyggnad - baserad på traditionella sakrala rum men utan religiös symbolik eller koppling. Vår vision är en plats där människor kan mötas och dela olika typer av ceremonier och ritualer men också finna andrum från vardagen, avskildhet och utrymme för eftertanke och kontemplation. Sverige sägs vara världens mest sekulära land. SamtidiThe aim for this our master thesis project is to create a sacred space in a modern ceremony-building without religious symbolism or connection. A place where people with different, or no, religious believes can meet and share different types of ceremonies but also find peace and quite for contemplation and reflection. Sweden is known to be one of the least religious countries in the world, but w

Purpose: The aim of this study is to discover whether team building activities positively affect team performance or not, by probing into the correlation of the components of high-performing teams. Consequently, the objective of this study is to develop the understanding of the effect of team building as well as probing into the factors which managers should consider when conducting team gathering

Förbättrad positionering av bröstcancerpatienter som genomgår strålbehandling Cirka 30 000 kvinnor får diagnosen cancer varje år i Sverige [1]. Av dessa utgör bröstcancer den vanligaste diagnosen med över 9000 fall per år [2]. Cancern kan vara begränsad till endast bröstet, men kan också ha spridit sig till de intilliggande lymfkörtlarna. Behandling av bröstcancer med körtelengagemang inleds vanlPurpose: The overall purpose of this master thesis was to investigate if the patient positioning could be improved for breast cancer patients with nodal involvement, using the optical scanning system Catalyst during patient setup. Patient motion during treatment and the effect it has on the dose distribution was also investigated. Materials and Methods: Eleven patients positioned according to the

En tredjedel av de män som diagnostiseras med cancer i Sverige idag diagnostiseras med prostatacancer. Prostatacancer är den vanligaste förkommande cancerformen i Sverige. Det finns flera behandlingsmetoder för prostatacancer, en utav dem är extern strålbehandling. Vid behandling med denna metod bestrålas prostatan med en strålkälla som befinner sig utanför kroppen. En liten stråldos ges vid fleraBackground and purpose: The MRI only workflow aims to base the treatment planning solely on magnetic resonance imaging (MRI), hence excluding the traditional computed tomography (CT) scan. To do that synthetic computed tomography (sCT) data is generated, replacing the conventional CT data. The aim of this study was to investigate the possibility of using cone beam computed tomography (CBCT) images

Det finns alltid en strävan att kunna uppskatta stråldoser på bättre och mer effektiva sätt. Om det så handlar om människor som blivit exponerade för joniserande strålning vid en olycka, ett attentat med radioaktiva ämnen eller för att mäta stråldoser på t ex. sjukhus. Idag finns det många kommersiellt tillgängliga alternativ för att utföra dosmätningar, så kallade dosimetrar. Samtidigt hade det vThere is always a need to improve and develop new ways of estimating effective doses to people and environments that have been exposed to ionizing radiation. Dose monitoring is also important in hospitals and the nuclear industry. Today there are several commercially available dosimeters, the most common being thermoluminescent dosimeters, TLDs, made from LiF. These are widely used for personal do

Jorden tar emot ett konstant flöde av energi via solinstrålning som sedan cirkulerar mellan atmosfären, haven och markytan innan den slutligen strålas ut i rymden. Dessa energiflöden är bränslet som driver planetens väder- och klimatfenomen och det vetenskapliga samfundet efterfrågar ökad kunskap om detta system för att utmaningarna med klimatförändringar ska kunna förutspås och hanteras. En grundFlows of energy between the atmosphere, the oceans and the land surfaces drive weather and climate on Earth. Increased understanding of these processes is crucial to successfully predict and address the challenges of climate change. Land surface models (LSM) are mathematical models designed to mimic natural processes and evolution of land surfaces with the basic task to simulate surface-atmosphere

Secure attachment representations, rooted in experiences with primary caregivers in early childhood, are considered a fundamental resource for a happy and healthy life. According to meta-analytical data, every third adult does not have secure attachment representations. Lacking secure attachment representations is associated with numerous health-related problems, perhaps mediated by increased susc

All businesses have a responsibility to respect human rights, including women’s rights. Whilst the UN Guiding Principles on Business and Human Rights acknowledge the vulnerabilities of women in the global value chains, there is limited guidance on what measures corporations should take in order to avoid and address women specific harms. Taking a rights-based approach to gender equality, this study

Network cameras has in the recent years become more powerful. Each camera is independent and has its own surveillance task. It is reasonable that network cameras in the future should cooperate together to increase surveillance effectiveness. There is a need to find cameras sharing the same field of view in order for an operator to switch perspective. This thesis investigates how multiple network c
