This paper presents an iterative decoder for faster-than-Nyquist (FTN) and orthogonal signaling multi-carrier systems. FTN signaling is a method of improving bandwidth efficiency at the expense of higher processing complexity in the transceiver. The decoder can switch between orthogonal and FTN signaling modes and exploits channel properties to improve bandwidth efficiency. The decoder is fabricat

This thesis investigated the modeling and control problems in the context of the flex-fuel compression-ignition (CI) engine and fuel cell, which shows great potential in the transition from fossil fuel to renewable energy sources.The modeling parts included the flex-fuel engine combustion process and intake system, and the system scale fuel cell model.The flex-fuel engine gas system models describ

IL-8 is a major human neutrophil chemoattractant at mucosal infection sites. This study examined the C-X-C chemokine response to mucosal infection, and, specifically, the role of macrophage inflammatory protein (MIP)-2, one of the mouse IL-8 equivalents, for neutrophil-epithelial interactions. Following intravesical Escherichia coli infection, several C-X-C chemokines were secreted into the urine,

To date, the most efficient perovskite solar cells (PSCs) require hole-transporting materials (HTMs) that are doped with hygroscopic additives to improve their performance. Unfortunately, such dopants negatively impact the overall PSCs stability and add cost and complexity to the device fabrication. Hence, there is a need to investigate new strategies to boost the typically modest performance of d

The frequent replacement of office furniture contributes to the increasing production of solid waste that leads to the use of more landfill space. Germany only produces approximately 700000 t of office furniture waste per year whereas most of this waste goes to landfill or incin-eration (Nolte, 2001). In addition, there are concerns about the use of hazardous chemicals in office furniture producti

In recent years the concept of “Blue carbon” has brought attention to the importance of Mangroves, Seagrass and Saltmarsh ecosystems in carbon cycles. Concerns over climate change has had countries commit to decreasing CO2 emissions, often using natural processes to sequester CO2. This trend has often followed a market approach through creating a monetary value and market for CO2. This Climate Fin

This report has been compiled within the framework of the programme on Regional Air Pollution in Developing Countries (RAPIDC), Phase III, conducted during the period 2005-2008. RAPIDC has been funded by the Department of Infrastructure and Economic Cooperation (INEC) of the Swedish International Development Cooperation Agency (SIDA). It is coordinated by the Stockholm Environmental Institute (SEI

Low carbon sustainability has been addressed in China’s national development strategies. This research explores individual behaviour change and engagement in building low carbon communities in China through a case study looking at the building of a low carbon campus at Fudan University, Shanghai. Individual behaviour directly influences the overall energy consumption and carbon emissions on Fudan

Electron injection from the transition metal complex Ru(dcbpy)(2)(NCS)(2) (dcbpy = 4,4'-dicarboxy-2,2'-bipyridine) into a titanium dioxide nanocrystalline film occurs on the femto- and picosecond time scales. Here we show that the dominating part of the electron transfer proceeds extremely rapidly from the initially populated, vibronically nonthermalized, singlet excited state, prior to electronic

The gel-forming MUC5AC and MUC5B mucins have been identified as major components of human airway mucus but it is not known whether additional mucin species, possibly with other functions, are also present. MUC16 mucin is a well-known serum marker for ovarian cancer, but the molecule has also been found on the ocular surface and in cervical secretions suggesting that it may play a role on the norma

In the philosophy of J. L. Schellenberg, “evolutionary religion” is a religious stance oriented towards the deep future. According to Schellenberg, the best form of evolutionary religion is non-doxastic faith in ultimism. I reject Schellenberg’s arguments for preferring ultimism and suggest that committing non-doxastically to traditional religion makes more sense from an evolutionary perspective.

Earlier studies have shown that when assessing explanations of psychological phenomena, there is a bias for explanations including references to neuroscience, even when these references contain logically irrelevant information (Fernandez-Duque, Evans, Christian & Hodges, 2015; M inahan & Siedlecki, 2016; Weisberg, Keil, Goodstein, Rawson and Gray, 2008; Weisberg, Taylor & Hopkins, 2015

The combination of solar heat and ground-source heat pumps in dwellings gives opportunities for optimising the use of renewable energy sources and minimize the share of bought energy. Solar collectors in the system may give advantages for the operational conditions both for the solar collectors and for the heat pump. The aim of this project was to analyse different variables such as energy demand,

District heating networks are an integral part of the energy system in many countries. In future smart energy systems, they are expected to enhance energy flexibility and support the integration of renewable and waste energy sources. An important aspect of these networks is the control of flow rates, which dictates the heat delivered to consumers. This paper concerns the properties of flow rates i
