This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. Also presented is a statistical method for relating the distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. Two
Popular Abstract in Swedish Denna avhandling undersöker dagvatten som en resurs i svensk urban miljö. Fokus har varit öppna dagvattensystem för flödeskontroll och uppsamlingssystem för regnvatten. För att analysera realiserandet av öppna dagvattensystem, presenteras två fallstudier; Augustenborg i Malmö och Bäckaslöv våtmark i Växjö. De kvarhållande och fördröjande effekterna som uppnås med gröna This thesis investigates the beneficial use of stormwater in Swedish urban environments. The focus has been on open stormwater systems for source control, as well as rainwater collection systems. To analyse the implementation of open stormwater systems, two case studies are presented: Augustenborg in Malmö and Bäckaslöv wetland in Växjö. The retention and detention effects of green-roofs have been
Offentlig upphandling är ett ämne där många har synpunkter och ämnet har också debatteras frekvent i media och inom den juridiska diskursen. Inte minst handlar det om miljökrav där också fler och fler använda sig ut av dessa krav i sina upphandlingar. Ett samordnade och stödjande arbete med råd om hur man kan ställa miljökrav har bedrivits, inte minst inom ramen för Miljöstyrningsrådet (MSR). SamPublic procurement has been frequently debated in news-media but also in the legal discourse, during the last years. Especially regarding the possibility to set environmental goals and we can see these requirements being more frequently used. Coordinating and supporting functions has been developed with advice on how to set these types of requirements. For example has MSR (Miljöstyrningsrådet) bee
Purpose - Food lost or wasted constitutes a substantial environmental, economic and social problem; today roughly one-third of edible parts of food that is produced for human consumption globally gets lost or wasted. Thus, a reduction of waste would contribute to a sustainable use of resources. It has been highlighted that packaging development has the potential to play an important role in this p
The thesis is based on a field study in Indonesia conducted in October-December 2001 and it focuses on one part of the Australian strategy for preventing asylum seekers from entering its borders in an irregular manner: an arrangement on the interception of asylum seekers transiting Indonesia en route to Australia. The Australian government argues that it wants to prevent secondary movements. It is
Purpose – The aim of this paper is to contribute with increased knowledge of the complex role of internal communication during a crisis like the COVID-19 pandemic. More specifically, the authors want to address the following research questions. How can the overall approach to internal crisis communication during the pandemic be interpreted, and what view of internal crisis communication does this
The Social and Solidarity Economy (SSE) have proved to combat inequalities, neoliberal policies, and ultimately, counteract the hegemonic economic rationale imposed by the market (Gaiger 2007). In particular, co-operatives are engaged in some market activity, although the economic principle does not prevail over the social objectives of the organisation. Indeed, this is the core of the social inno
The purpose of this study was to investigate the applicability of data-driven experimental design for the optimization of a hard coating for cutting tools in metal machining. The complexity of metal machining leads to difficulty in theoretically modeling and understanding the interactions and correlations between parameters and performance. Because of this and the importance of incremental perform
The advent of optogenetic tools has had a profound impact on modern neuroscience research, revolutionizing our understanding of the brain. These tools offer a remarkable ability to precisely manipulate specific groups of neurons with an unprecedented level of temporal precision, on the order of milliseconds. This breakthrough has significantly advanced our knowledge of various physiological and pa
The WT1 protein, a product of the Wilms’ tumour 1 gene (WT1) is a zinc finger transcription factor implicated in a number of cellular processes particularly involved in the development of the urogenital system. Mutations in this gene have been implicated in abnormal development of the urogenital system resulting in syndromes such as the Denys-Drash, WAGR and Frasier and in the childhood kidney mal
In semiarid and arid Tunisia, water quality and agricultural practices are the major contributing factors to the degradation of soil resources threatening the sustainability of irrigation systems and agricultural productivity. Nowadays, about 50% of the total irrigated areas in Tunisia are considered at high risk for salinization. The aim of this thesis was to study soil management and salinity re
The thesis deals with experiments and numerical simulations of adiabatic laminar premixed flames anchored to a heat-flux burner using different mixtures under various operating conditions. The aim is to obtain a better understanding of cellular instability in heat-flux burner anchored flames. Numerical and experimental studies were carried out to characterize the onset and the evolution of cellula
This thesis presents work aimed at the development and application of a new lithography system for direct material patterning with the MeV proton beam at the Lund Nuclear Microprobe (NMP) facility. MeV proton beams are advantageous for use as a patterning tool due to their deep and well defined penetration through matter and their highly local energy deposition. This allows the fabrication of thre
In regard to the energy sector, it is generally presumed that in post-Lisbon era and since the adoption of Third Energy Package the Member States and institutions of the Union act in a shared format. However, by developing new legislation in the field, supra-national institutions tend to shift the competence away from shared (as it currently stands). Even if the guidelines for decisions granting e
I syfte att bekämpa grov brottslighet vidtar svenska myndigheter olika provokativa åtgärder, däribland brottsprovokation. Otillbörlig brottsprovokation innebär att någon provoceras att begå ett brott som denne annars inte hade begått. Detta är idag otillåtet, både enligt svensk rätt och enligt Europeiska konventionen om skydd för de mänskliga rättigheterna och de grundläggande fri- och rättigheterIn order to combat serious crime, Swedish authorities implement provocative actions, including entrapment. Undue entrapment means that someone is provoked to commit a crime that he or she would not otherwise have committed. This is currently prohibited, both under Swedish law and under the European Convention on Human Rights (ECHR). The purpose of the prohibition of such entrapment is to protect t
När ett barn placeras i ett familjehem, med anledning av missförhållanden i ursprungshemmet, är grundprincipen att barnet så snart det är möjligt ska återvända hem. För att omhändertagandet inte ska utgöra en kränkning av barnets rätt till familjeliv, måste myndigheterna arbeta aktivt för att få till ett återförenande. Samtidigt har det i olika rättsliga dokument och rättspraxis utvecklats en prinWhen a child is placed in foster care, the basic principle is that the child should return home as soon as possible. In order for the treatment not to constitute a violation of the child's right to family life, the authorities must work actively to reunite the family. At the same time, a principle has been developed in various legal documents and case law, whereby continuity and stability must
Det kan konstateras utan vidare att den världen som vi lever i håller på att bli allt mer digitaliserad. Människor kommunicerar på Facebook, beställer varor på Amazon och använder sig av Google Search för att komma åt allting som Internetet har att erbjuda. En gemensam nämnare för dessa tjänster är att de erbjuds gratis. Affärsmodellen för dessa företag är istället att maximera upptagningen av datIt goes without saying that the world that we live in is becoming increasingly digitised. People communicate on Facebook, order products on Amazon, and use Google Search to find everything the Internet has to offer. A common denominator of these services is that they are all offered for free. Instead of requiring payment, the business model of such undertakings is to maximise data collection on it
The adoption of the General Data Protection Regulation proclaimed Europe’s stance on the significance of the right to data privacy today whereas digital technologies have prevailed all around the globe and all spheres of our lives. Digitalization is thus a phenomenon that has ever since drawn attention from leaders and policymakers which why the Regulation along with other European privacy regimes
The purpose of my Master Thesis is to examine, in detail, how current international law relates to autonomous weapon systems. The background for this project is that the requirement of current international humanitarian law presupposes that the characters of war, namely soldiers and military officers, are human beings. Warfare has, however, changed increasingly since the Geneva Conventions were wr
In the radiation or early matter dominated eras of the Universe, there is a theoretical possibility for the formation of black holes (BHs). These primordial black holes (PBHs) have been thought of as a possible candidate for dark matter (DM), and an attractive one at that as it would explain DM using only baryonic physics. Constraints from theory and observations such as microlensing has nearly ex
