In the initial stage of planning, considering the solar impact of urban layout on the building can effectively avoid some irreversible design issues, improve the indoor environment, and reduce energy demand. The typical architectural models of three representative cities (Copenhagen, Berlin and Hong Kong) were selected as the analysis cases in this study. By analysing several sunlight and solar me
Arkiv används ofta som en källa inom olika forskningsprojekt. I den här uppsatsen är det istället arkivet i sig som är studieobjekt. Utifrån mediearkeologisk teori undersöks Biblioteksstyrelsens arkiv i Åmål. Uppsatsens teoretiska utgångspunkter är att arkiv befinner sig i en samhällelig kontext och återspeglar det minne det lagrar. Uppsatsen är en kvalitativ studie och arkivet har undersökts på fArchives are often used as a source in various research projects. In this essay, it is instead the archive that is a study object. Based on media archaeological theory, the Library Board's archive in Åmål is examined. The theoretical basis of the essay is that archives are in a social context and reflect the memory it stores. It is a qualitative study and the archive has been investigated on s
Previous research indicate that social and ecological sustainability dimensions are handled separately within the work of goal fulfilment. Important key actors are having a hard time finding synergies between them which leads to a slower green and healthy transformation of cities. On the local level, this problem is connected to the decentralization of municipalities due to their growing assig
High fuel prices and stringent emission norms stimulate the improvement of engine efficiency and emission reductions. This is one of the leading issues in the truck industry. A waste heat recovery technology (WHR) can be used to solve this issue. The evaporative cycle represents the WHR. This thesis is part of a research project which is carried out at the department of Energy Science at Lund Univ
This thesis investigates numerically the out of equilibrium properties of quantum rings with magnetic impurities, using the periodic Anderson model (PAM). The model is a simple template for the discussion of the physics of regular arrays of rare-earth impurities in metallic hosts. The system considered is a quantum ring consisting of up to six sites, each of whom are connected to an Anderson impur
In the food industry, increasing market competition has seen intensified efforts in finding new solutions for safer, more efficient and higher quality production systems. If the established conditions of the production allows for the automation of processes, there is a substantial potential to achieve those various improvements throughout the production. Since each production system is unique and
This paper investigates the impact of information spillovers on the export entry decision of Chinese manufacturers between 2000 and 2006 by using a combination of firm and transaction level data that allows to track the occurrence of individual export starts and captures the extent of local export agglomeration at a detailed geographical level. We examine if the presence of neighboring exporters i
This thesis critically examines the issue of shared border sewage between San Diego and Tijuana. In light of the recent sewage spill in February of 2017, dumping 143 million gallons of raw sewage into the Tijuana River, the phenomena of border sewage in the transnational environment of the Tijuana River Watershed has been a topic of interest in local and international contexts; raising questions o
The round goby (Neogobius melanostomus) is a non-indigenous species to the Baltic Sea that has drawn the attention of many researchers in the last decade due to its rapid spreading and its impact on the local fauna. With recent concerns about the dispersal of the round goby towards the North Sea, the aim of this study was to determine if the native shore crab could compete with the invaders and pr
The rise of private firms was vital for China’s coastal economic development, and this institutional change should play an essential role if the country wants to replicate its successes elsewhere. The first testing ground for such replication is the Go West Program. Aimed at the catching up of China’s interior, the program uses the city of Chongqing as a growth pole. Based on the coastal experienc
This paper presents a fully integrated 60 GHz frontend for phased array receivers. For the first time in the literature a phase controlled phased locked loop (PC-PLL) is used for beamforming at 60 GHz. The front-end performs a two stage frequency down-conversion, first from 60 GHz to 20 GHz, then from 20 GHz to quadrature baseband. Both the local oscillator signals at 20 GHz and 40 GHz are generat
District heating and cooling systems have been undergoing continuous development and have now reached the fifth-generation. In this innovative technology, connected buildings share local excess energy that otherwise would be wasted, which consequently reduces primary energy demands and carbon emissions. To date, the issue of implementing fifth-generation district systems on existing buildings has
In the context of the COVID-19 pandemic, we aim to identify and understand the obstacles and barriers in applying electronic exams successfully in the process of distance education. We followed an exploratory descriptive approach through a questionnaire (one general, open question) with a sample of university teachers and students in four of the largest universities Palestinian in Gaza. A total of
Little is known about provision of medical services to adolescents prior to participating in international top-level sports. This study aimed to investigate experiences of medical service provision among high-level adolescent athletics (track and field) athletes from three continents. A thematic narrative analysis was applied to data collected from 14 athletes by semi-structured interviews. Althou
The present study numerically investigates the second law analysis of turbulent flow in novel outward helical corrugated tubes by using a Reynolds Stress Model (RSM). A case of a transverse corrugated tube and five cases of helical corrugated tubes with different height-to-diameter ratios and pitch-to-diameter ratios are examined with Reynolds number ranging from 3800 to 43,800 at a constant wall
Livestock production is important for local food security and as a source of income in sub-Saharan Africa. The human population of the region is expected to double by 2050, and at the same time climate change is predicted to negatively affect grazing resources vital to livestock. Therefore, it is essential to model the potential grazing output of sub-Saharan Africa in both present and future clima
This paper examines the linkages between cash-crop income and other dimensions of poverty to interrogate assumptions regarding the relationship between agricultural income and poverty alleviation. The analysis treats poverty as a multi-dimensional and socially disaggregated phenomenon. The paper employs a mixed methods approach to case studies of Ghana and Ethiopia to explore two critical issues.
The high endwall heat transfer in the junction of the hub and vane/blade is very crucial in turbomachinery and is of great concern for increasing the gas turbine inlet temperature but avoiding hot spots. The vortices generated in that region are mainly responsible for the high heat transfer. By controlling these vortices, heat transfer in the junction region can be controlled. In this study, a new
A number of recent experiments have indicated that magnetic nanoparticles can become locally hotter than their nonmagnetic surroundings during induction heating. While such nanoscale hotspot-effect is particularly attractive for applications within biomedicine and catalysis, its existence is a topic of scientific controversy. To address this, we here present simultaneous measurements of the intern
In this investigation, we have collected family-structured data from a partly self-compatible, outcrossing population of Brassica cretica to estimate and compare the effects of one-generation selfing on different types of characters. Inbreeding not only depressed characters that should be positively correlated with fitness irrespective of habitat, e.g. germinability, leaf number and inflorescence
