Long term evaluation of an asymmetric CPC PV-thermal hybrid built for high latitudes, MaReCo (MaximumReflectorCollector), is performed in Lund, lat 55.7o, and this paper discusses output estimates and characteristics of the system. The output estimates are calculated using the MINSUN simulation program. To get the input for MINSUN, measurements were performed on two MaReCo prototypes. These measur
In recent years, thermographic phosphors used for surface temperature measurements have been developed to suit combustion applications. Pulsed ultraviolet laser radiation at 266 nm and 7 ns duration was used to excite a thermographic phosphor, Mg4FGeO6:Mn, which was adapted to the surface of the investigated material. The laser-induced emission from the phosphor was recorded. A calibration of the
Recent work has highlighted the potential benefits of exploiting ellipsoidal uncertainty-set-based robust Capon beamformer (RCB) techniques in passive sonar. Regrettably, the computational complexity required to form RCB weights is cubic in the number of adaptive degrees of freedom, which is often prohibitive in practice. For this reason, several low-complexity techniques for computing RCB weights
Aim: The aim of the present study was to retrospectively investigate the impact of induction chemotherapy on treatment outcome in patients treated with curatively intended radiotherapy for non-small cell lung cancer (NSCLC). Patients and Methods: Patients with a diagnosed NSCLC that have been subjected to curatively intended irradiation (>= 50 Gy) and treated in an oncology department in Sweden du
Background: The aim of this study was to evaluate the day-care interventions implemented in southern Sweden to restrict the dispersion of penicillin-non-susceptible pneumococci with a minimum inhibitory concentration of penicillin G of at least 0.5 mg/l (PNSP0.5). Methods: A retrospective epidemiological study was performed and data from 109 day-care centre interventions from 2000 to 2010 were ana
The aim of the overview is to give a perspective of global biobank development is given in a view of positioning biobanking as a key resource for healthcare to identify new potential markers that can be used in patient diagnosis and complement the targeted personalized drug treatment. The fast progression of biobanks around the world is becoming an important resource for society where the patient
Världen över finns det idag flickor, kvinnor och pojkar som inte får leva ut sin fulla potential, som inte får njuta av sina mänskliga och grundläggande rättigheter och friheter. Människor som förtrycks, utsätts för våld och i värsta fall även berövas livet. Deras brott är att de vill leva sina liv, såsom de själva vill. Hedersrelaterat våld och förtryck är ett angeläget samhällsproblem som angå
Valuing single-name Credit Default Swaps (CDS) is a dicult task since in order to make a fair valuation, one needs to assess the credit risk of the corresponding company. Many dierent models exist when it comes to modelling the credit risk, this report specically focuses on the branch of models named structural models. The aim of this thesis is to, for a number of companies, model the CDSspreads g
I examensarbetet gjordes fyra variationer av en modell med målet att simulera torkningen av bark. Alla fyra variationerna jämfördes med experimentella data från en pilotanläggning och värme- och massöverföringskoefficienten kalibrerades mot experimentella data. De fyra modellvariationerna är: • Adiabatisk mättningsmodell • Värme och massöverföringskoefficientsmodell • Isotermmodell • FraktionsmodeDuring this master thesis four variation of a model were created with the goal to simulate the drying process of bark. All four variations were compared with experimental data from a pilot plant and heat and mass transfer coefficient were calibrated against the experimental data. The four model variations are: • Adiabatic saturation model • Heat and mass transfer coefficient model • Isotherm model
The BRIC countries have been in a process of fast economic growth for more than a decade and the growth seems to continue. Economic growth is often linked to the use of fossil fuels and the release of greenhouse gases. The accumulation in the atmosphere of greenhouse gases contribute to global warming and the risk for climate change. The objective is to study the impact on global environment of th
Eutrophication is one of the biggest environmental problems in Scanian waters, where agriculture has the largest input. Through soil cultivation and usage of fertilizers, nutrients are added and released. If no uptake occurs nutrients can be further transported to watercourses through surface runoff or the drainage system. This study investigates three measures to reduce and reuse nutrients from d
The study focuses on the efforts surrounding youth delinquency from the perspectives of persons working in state and non-profit organizations. The aim is to investigate how the respondents perceive their roles in this endeavor and how these roles differ from each other. This is done to gain an understanding of society's work against youth delinquency. The methods employed in the study include
In aviation, pilots engage in safety critical activities in the cockpit to guarantee a safe flight. Throughout history these activities have been transformed by introducing new artifacts in the cockpit, such as rules and technology, changing thereby the way in which pilots try to achieve safe flight outcomes. The recent introduction of the iPad in the cockpit of airlines, as part of the process of
Bakgrund: Varje dag förmedlar aktieanalytiker världen över analyser och rekommendationer. Eftersom analytikerna spenderar sina dagar med att tolka all tillgänglig information på marknaden är det rimligt att anta att dessa personer är de bästa på att värdera bolag. Därmed kan det tänkas vara en bra strategi för den småsparare som inte själv har kunskap, lust eller tid att basera en strategi på dera
RTK GNSS is a way of deciding the position of a GNSS receiver with high precision. It should theoretically be possible to determine the position with the precision of a couple of centimeters. Traditionally the RTK GNSS system consists of a base station and a rover. The base station knows its position and compares that to the information it gets from the satellites in order to calculate the error.
This thesis investigates the ecological and urban regeneration of the Svisloch River in Minsk, focusing on its central urban segment. Historically a natural watercourse and public axis, the Svisloch has undergone a significant transformation into a technically regulated water body, reflecting the city's changing priorities as a result of Soviet-era infrastructure development and contemporary u
I Sverige pågår en elektrifiering av samhället, där transporter, industrier och hushåll i allt större utsträckning försöker övergå till el som energibärare. Detta är en central del i att nå våra klimatmål, men ställer samtidigt höga krav på elsystemets kapacitet. För att kunna planera för ett robust och hållbart elnät krävs en förståelse för hur el används idag. I denna rapport ligger fokus på attThis report aims to develop general synthetic load profiles representing electricity consumption in Swe- dish single-family homes. Based on historical hourly consumption data from Lomma and Helsingborg, provided by RISE, three models – SARIMAX, GRU, and Prophet – were trained and evaluated. To enable comparison and future scalability, the data was normalized by each user’s annual consumption. Amon
During Chávez’s presidency (1999-2013), Venezuela experienced an increase in lethal violence, becoming one of the most violent countries in the world. In contrast, Ecuador saw a significant decline in homicide rates during the presidency of Correa (2007-2017). This thesis examines why two countries with similar conditions such as oil dependency, socialist governments and geographical locations, ex
This study examines why some separatist insurgencies negotiate while others continue armed struggle, focusing on BRN-C in Southern Thailand and the Kachin Independence Organization (KIO) in Myanmar. Despite similar ethnoreligious, peripheral, and long-standing conflicts, BRN-C entered negotiations with the Thai state in 2025, while KIO continued its insurgency. Using a Most Similar Different Outco
