This thesis proposes a novel method for multi-pitch estimation. The method operates by posing pitch estimation as a sparse recovery problem which is solved using convex optimization techniques. In that respect, it is an extension of an earlier presented estimation method based on the group-LASSO. However, by introducing an adaptive total variation penalty, the proposed method requires fewer user s
Produktionsvåtmarker – lika bra för alla syften? Produktionsvåtmarker kan vara ett bra verktyg för att motverka övergödningen av våra hav och vattendrag. Detta eftersom produktionsvåtmarker genom till exempel växtupptag kan fånga in näring samtidigt som växter och djur får ett bättre och mer varierat landskap. Växtbiomassan kan sedan skördas och användas som resurs för biogasproduktion. Hur väl vModern agricultural practices give rise to environmental issues such as the eutrophication of waters (e.g. rivers and oceans). Increased knowledge and understanding of the negative consequences of nutritional leakage have led to comprehensive mitigation measures, one of which is the construction of wetlands. In order to achieve successful, cost-effective and sustainable measures it is essential to
Learning partnerships are becoming increasingly common for municipalities to fulfill their roles as important actors in adaptive governance regimes for sustainability. However, there is little theoretical guidance for municipalities, endangering the effectiveness of partnerships. The Ball-Bearing Framework used in this thesis is one of the first attempts to understand inter-municipal partnerships,
Nästan alla moderna programspråk använder en interpretator – en flexibel och praktisk om än långsam lösning. Vi prövar ett enkelt sätt att kraftigt öka prestandan på Erlangs interpretator.We have modified the Erlang runtime to add support for a tracing just-in-time (JIT) compiler, similar to Mozilla’s TraceMonkey. Tracing is a technique to augment an existing interpreter with a JIT simply by recording the instructions executed during a loop iteration, and then generate optimized native code from this. Tracing compilers are particularly suited to optimize number crunching tight loo
This paper seeks to outline the implications of an increasingly entrepreneurial mindset among top and middle management on the execution of key managerial activities in a successful strategic implementation and the interrelated outcomes. The intention is the draw valid managerial implications for those considering strategic change as well as implications for future research. The research contribut
Detta är en kvalitativ studie som studerar medialt uppmärksammade skandaler utifrån en fallstudie. Genom analyser av fem intervjuer med anställda på det statliga företaget Systembolaget, samt innehållsanalyser på artiklar från Dagens Nyheter och Aftonbladet har syftet med denna uppsats varit att undersöka vilken betydelse och funktion medierna har vid konstruerandet av en skandal, hur de framställ
This thesis explores a group of young Western-oriented Chinese consumers called xiaozi in Shanghai, comprised mainly by young individuals from an urban lower middle-class background who attempt at adopting a lifestyle and identity marked by a taste for fine arts and foreign culture. The study shows that by means of social distinction through taste and foreign cultural practices the xiaozi youth ca
My purpose of this study was to examine LSS staffs’ (LSS: The Swedish Act concerning support and service for persons with certain functional Impairments) consideration of clients’ needs and self-determination as well as the staffs’ own power in the use of coercion and restraint in the work with clients in group housings. My study was based on five interviews with staff from two different group hou
A purchasing cost model is a tool used to facilitate decision-making for selection, evaluation and development of suppliers. The model consists of a set of cost components, which at the bottom line constitute a total cost for a certain purchase. Different models cover different areas of purchasing, but in general the transaction of a purchase is central and then additional areas such as supplier m
In 1973, the psychologist Tajfel proposed the Social Identity Theory which claimed that human behaviour is affected by the social relation of the people involved in a given situation, as documented by Burke (2006). The culture and language of Japan seem to embody the aspects of this theory as social relation is portrayed frequently, if not constantly, through the use of language. Academics such as
Studien undersökte hur förhållandet mellan arbetsklimat och arbetsmotivation såg ut på två olika arbetsplatser. Teorier kring skapande, förekomst och avsaknad av ett positivt arbetsklimat och arbetsmotivation behandlades. De organisationer som undersöktes var dels ett lager/logistik-företag samt en livsmedelsproducent. Tre hypoteser ställdes: 1. Det finns en korrelation mellan individens upplevda The purpose of the study was to examine the relationship between a positive work climate and work motivation at two different organisations. Theories regarding creation, presence and lack of work climate and work motivation were discussed. The companies taking part in the study were a warehouse/logistics company and a producer of food. Three hypothesis ́ were set: 1. There is a correlation between

[Translated title] Supervisor: Eva Palmblad Assessor: Weddig Runquist The aim of this essay was to study, from a social worker’s point of view, their thoughts and experiences in helping children who
Heta Jupitrar är gasjättar som Jupiter vars omloppsbana för dem närmre sin värdstjärna än Merkurius bana kring Solen. Sen deras upptäckt har de visat sig vara väldigt viktiga i vår förståelse för exoplanet-atmosfärer. På Jorden minskar temperaturen av atmosfären med höjd över marken, förutom i ett område där temperaturen plötsligt går upp igen då ozonet som fångar UV-ljuset befinner sig på den höjContext. The discovery of hot Jupiters, giant gas exoplanets on tight orbits close to their host star, has proven instrumental in the study of exoplanet atmospheres through transit spectroscopy. Just as a temperature increase with height manifests in Earth’s atmosphere due to ozone absorbing ultraviolet radiation, transit spectra of some hot Jupiters has yielded evidence that suggests the presence
Dagens föränderliga och dynamiska marknad har lett till att organisationer tvingas vara flexibla för att snabbare kunna fatta beslut och anpassa sig. Vidare har detta lett till en förändring inom Business Intelligence (BI), där en nyare lösning kallad Self-Service Business Intelligence (SSBI) har vuxit fram. SSBI syftar huvudsakligen till att förbättra beslutsfattande i organisationer genom att gö
People depend on the benefits derived from nature, so called ecosystem services (ES). ES are a promising framework to evaluate ecosystems and promote conservation, but they are also difficult to measure and visualize, and the accuracy of such efforts is questionable as a basis for land management. In this thesis, I both measured and problematized the measurement of ES. In the first part of this th

Biotechnology companies are characterized by long development and capital intensive processes, which includes certain risks throughout the development chain. When attracting investments from VC funds, specific portfolio strategies and evaluation criteria drive the decision making for investors, and biotechnology companies can face significant challenges in knowing what investors seek. Also, due to
