Biomass is often viewed as a primitive source of energy that needs to be modernized. However, itis unlikely that preferred modern energy sources will displace traditional biomass-based energyin the near term, especially in rural Africa and southeast Asia (FAO 2017). Demand for sustainablysourced biomass is likely to increase as the world moves away from fossil fuel dependence andtransitions to sus
MAX IV and SOLARIS are two synchrotron light sources located in Lund and in Krakow, respectively. A stripline is a standard multi-purpose component that is used in many accelerators and consists of one or multiple electrodes. The currents that are induced by the Lorentz contracted fields of the electron beam at the electrodes can be used for beam diagnostics, or one can excite the electrodes in or
Collaborative networks are widely employed as mechanisms to develop innovative responses in challenging environments. This approach has relevance in the area of regional development particularly where food production and tourism are two significant sectors underpinning regions. These two industries have conventionally operated as single sectors independent of each other. However, an inability to r
Cities face multiple social-ecological challenges, which nature-based solutions (NBS) promise to address. Strategies to mainstream NBS have only achieved partial success, hence recent studies suggest that inner dimensions - mindsets and transformative capacities - must be mainstreamed simultaneously. This study investigates municipal employees' engagement with inner dimensions, its impact on s
Som en del i utvecklingen mot grönare och miljövänligare processer, samt ett behov av ytterst specifika reaktioner, vill AAK AB utvidga sin användning av lipaser i sin produktion av strukturerade triacylglyceroler (STAGs). AAK vill bygga upp ett bibliotek av utvärderade lipaser. Syftet med detta examensarbete är att bidra till detta bibliotek genom att karakterisera en grupp kommersiellt tillgänglAs part of a switch towards more green and environmentally friendly processes, together with a need for highly specific reactions, AAK AB wants to broaden their use of lipases in the production of structured triacylglycerols (STAGs). AAK are working on creating a lipase library where several lipases are evaluated, this master thesis aims to contribute to this lipase library by characterizing a sel
Entreprenörskap karaktäriseras av en snabbföränderlig och osäker miljö. I tillägg har intressenter i området olika perspektiv och bekymmer samt är beroende av varandra. För att en ny affärsverksamhet ska lyckas är finansiering och humant kapital ofta viktiga faktorer, särskilt inom tech, och i dagsläget är det svårt att skapa/uppnå ”rätt” koppling i samspelet mellan unga företag (ideators), investThe field of entrepreneurship is characterized by a fast-changing and uncertain environment. In addition, stakeholders within the field all come with different perspectives and concerns and are dependent upon each other. For a new business to be successful, financing and human capital are often determinants, especially within tech, and it is difficult to attain the “right” connections between youn
Femtosecond pulse shaping is a versatile tool that enables the generation of ultrashort laser pulses with nearly arbitrary temporal shapes. Among others, the technique is of use in ultrafast spectroscopy experiments where it can be employed for dispersion control and the generation of well-defined laser pulse sequences. In this work, a Fourier-transform pulse shaper based on a pixelated liquid crys
In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a
The Laser Interferometer Space Antenna (LISA) is a space borne gravitational wave detec- tor set to launch in 2034, with the objective of detecting and studying the Gravitational Waves (GWs) of our universe. So far, ground-based detectors such as the Laser Interferometer Gravitational-Wave Observatory (LIGO) have been successful in detecting GWs, but the limitations of ground based detectors is wh
Machine learning as a field has expanded in an explosive manner, with more companies interested in using the technology. One of these companies, Spiideo, uses Machine learning to automatically stream and record sports, highlighting key events - all automatically without a cameraman. However, these cameras have to undergo a lengthy calibration process involving manual feature extraction. This work
Ultra millimeter-wave (mmWave) radars have become a vital sensor in automotive, surveillance, and consumer electronics thanks to its precise measurements and low power consumption. However, they required a precise control to coordinate their different modules and produce meaningful data. In this thesis work, we introduce an approach to perform the control and coordination of the radar based in mic
Det här examensarbetet utvecklar ett koncept för infästning av fenor på jetboards som inte intränger på befintliga patent. Det resulterande konceptet medför handlingsfrihet (FTO) och följaktligen tillåter produktion av fenor med originell design. FTO innebär möjligheten till att producera och sälja en produkt utan rättsligt ansvar gentemot ägare av patent. Examensarbetet presenterar och diskuterarThis master thesis generates a concept for the means of attaching fins onto jetboards without infringing on existing patents. The resulting concept establishes freedom to operate (FTO) and enables production of fins with original designs. FTO meaning the possibility of producing and selling a product without legal liability to any patent holders. The thesis further presents and discusses user need
Better access to finance and higher education levels in a country are two major policy areas of governments and international development cooperation organisations for the goal of reducing poverty. Microfinance has become a popular instrument to facilitate access to finance, but comparative evidence on a macro scale is scarce. This thesis examines the relative importance of the two policy areas us
The measurement of ensemble variability in time-aligned event signals is studied in relation to sampling rate requirements. The theoretical analysis is based on statistical modelling of time misalignment in which the time resolution is limited by the length of the sampling interval. For different signal-to-noise ratios (SNRs), the sampling rate is derived which limits the misalignment effect to le
Popular Abstract in Swedish I och med de smarta mobiltelefonernas framväxt överförs allt mer data i de mobila nätverken. Detta ställer allt högre krav på mobilsystemen och de mobila enheterna. Ett effektivt utnyttjande av de tillgängliga resurserna är nödvändigt. Det tillgängliga frekvensspektrat är begränsat och måste utnyttjas så väl som möjligt. Detta görs bland annat genom att öka mängden dataIn this thesis different aspects of baseband implementation of mobile communication systems is treated. The content is focused on symbol detection and channel estimation in MIMO and OFDM. The thesis deals with the complete chain from algorithm to silicon implementation within these areas. The main contribution of this thesis is described in the included papers. The first paper handles symbol dete
In this thesis we study several combinatorial problems in algorithmic graph theory and computational biology, and different algorithmical approaches for solving them. In particular, we focus on graph algorithms, seeking for the most part polynomial or sub-exponential exact solutions, but in some cases also approximate solutions. In the first part we study two problems on phylogenetic trees, the pr
Endovascular aortic repair of aortic pathologies has become widely spread among vascular surgeons. Much focus has been directed at perfecting and developing endovascular procedures to treat evermore-complex issues. Much less focus has been directed at the radiation hazards to patients as well as operators and staff when such procedures are performed. Radiation exposure must be used according to th
