We report a new method to select the optimal actuation frequencies in bulk acoustophoretic devices, by means of differential impedance spectral analysis measured via the actuating piezoelectric transducer (piezo). The impedance spectra are rich of large spurious resonance peaks originating from bulk resonances not related to the channel resonance why direct measurement of the piezo impedance spect

Despite the important roles volunteer workers in not-for-profit organization play in improving the quality of individual lives in various aspect, only a handful of research focusing on volunteer workers have been conducted. There are two main purposes for this study. First, to examine how overall volunteer workers in not-for-profit organizations view their working experience by analyzing the stren
Destructive leadership is a phenomenon widely known in organizations and may have severe consequences in high-risk environments such as the construction industry. The present study investigated the measurement of and relationship between safety climate, destructive leadership, and risk behavior on 2 construction sites in Sweden. It was assumed that the Destrudo-L exhibits at least an acceptable le
The topic of the thesis was Buddhist environmental activism in South Korea. The purpose of the study was to portray the activism and social engagement of Korean Buddhists to conserve the environment and to motivate the awareness of the people in how environmental destruction affects nature and society. This was done to then examine how Buddhist environmental activism is expressed in Korea, if work
National image as one important source of soft power has been paid close attention in China. This thesis examines China’s new national image shaping in the framework of ambitious Belt and Road Initiative (BRI), in the same time, how other countries like Pakistan and India respond to China’s self-image are discussed. By using Fairclough and Foucault’s critical discourse analysis, the thesis argues
Detta arbete har undersökt hur ett neuralt nätverk bör tränas för att utlinjera hjärtmuskeln i MR-bilder. Med en begränsad mängd data såg vi hur man bör behandla sin data för att producera en välfungerande modell.A convolutional neural network for automatic myocardial segmentation of MR images is described and implemented, based on the readily available architecture SegNet. A general network trained on both end-systolic and end-diastolic images is determined to be superior to the networks trained on the separate data. The evaluation of myocardial segmentation is discussed, as well as the importance of manu
Dagligen ingås det mängder av avtal näringsidkare emellan. Grundprincipen är att det råder avtalsfrihet och att varje part får stå för sina egna risker. Efter införandet av 36 § avtalslagen år 1976, öppnades dock en möjlighet för avtalsparter att få ett avtal jämkat eller ogiltigförklarat i domstol med hjälp av denna generalklausul. 36 § är en mycket omfattande paragraf och innefattar många tänkbaEvery day there are a lot of agreements between traders. The basic principle is that there is freedom of contract and that each party must bear its own risks. After the introduction of Article 36 of the Contracts Act in 1976, an opportunity was opened for contractors to get an agreement adjusted or void in court, with the help of this general clause. The paragraph is very immersive and involves lo
Tidigare forskning har visat på att sömn stärker minnen. Denna studie ämnade att utforska detta i en verklig situation genom att studera sömns effekt på vittnesmål. De 18 deltagarna fick se en video av en fiktiv misshandel och efter 12 timmar, där hälften av deltagarna var vakna under dagen och andra hälften av deltagarna sov under natten. De fick svara på ett minnestest om videon. Frågorna var inPrevious studies have shown that sleep strengthens memory. The current study has put this into a real-life context and study sleep’s effect on witness testimony. The 18 participants watched a video of a fictitious assault, and after a 12-hour delay, where half stayed awake during the day, and half slept during the night. They answered a questionnaire about the video, as a memory test. The question
The subject of this thesis is human activity recognition in health care. The data set used is the SBHAR data set. It contains accelerometer and gyroscope of 30 different individuals walking, walking upwards, walking downwards, sitting, standing and lying. The research questions is: How can we, using deep learning, understand more about and potentiallly improve Human activity recognition or HAR for
Heterogeneous team collaboration is a fundamental component of Disaster Risk Management (DRM). However, DRM teams face complex-dynamic situations characterised by high disruptions, distributed locations and other factors, which create persistent problems for team collaboration. In these contexts, even the smallest improvement to our understanding has the potential to yield enormous benefits to DRM
Uppsatsens syfte är att undersöka om lärarstudenterna har förändrat sitt förhållningssätt till begreppet och ämnet bedömning, och hur detta i så fall tar sig uttryck och avspeglas i deras språk. Tre forskningsfrågor formulerades utifrån detta syfte som hur studenterna talar om bedömning, vilka modalitetsuttryck de använder i förhållande till begreppet och ämnet bedömning och om där finns en föränd
Om någon vill ändra användningen av en byggnad, bygga till eller bygga nytt krävs oftast bygglov. Beslut om bygglov fattas av byggnadsnämnden. Om den sökta åtgärden vidtas utanför detaljplan skall alltid sakägare höras och ges tillfälle att yttra sig. Om den sökta åtgärden verkställs inom detaljplanerat område behöver detta endast ske om åtgärden innebär en avvikelse från detaljplanen. ExamensarbTo change the features of a existing building or to build a new building a building permit is needed. The building department at the municipality decides about building permits. The building departments inspection of the applied building permit are a public law inspection and are limited by the Planning and Building Act. Civil rights as ownership and easements are not to be included in the buildin
Examensarbetet är en dokumentation och undersökning av det existerande bruksområdet i Orrefors, Småland. Utgångspunkten för detta är att glasbruket lade ned sin produktion år 2013. Vidare utforskar detta projekt hur bruksområdets östra del kan vidareutvecklas för att hålla samma höga kvalitet i rumslighet som sin västra motsvarighet. Arbetet handlar också om att åter ta i anspråk tidigare brukslok
SpectraCure AB is a start-up company aiming at treating internal solid tumours such as prostate tumours with an innovative technology called ‘Interstitial Photodynamic Therapy’. This treatment requires the use of fibres to deliver the amount of light required to activate a drug injected to the patient which leads to the destruction of the tumours. This treatment is patient-based which means that t
The enactment of the Water Sustainability Act by the province of British Columbia, Canada, in 2016 signals a shift towards a more decentralized and localized approach to water governance in the province. In this context, this thesis explores the history of development in the socio- ecologically significant Fraser Basin and identifies that a unique and successful form of collective- action to addre
Den gåtfulla gränsytan mellan lipid och vatten Lipider är amfifila, vilket betyder att de består av en hydrofil och en hydrofob del. Vid kontakt med vatten arrangerar de sig i strukturer för att undvika oönskad interaktion. Den gränsyta som uppstår mellan vatten och lipider är intressant, eftersom den spelar en viktig roll i många processer, såsom nedbrytning av lipider med så kallade lipaser. TrThe triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. The enzyme attracts interest in industrial applications of the catalytic behavior it possesses, such as in food and pharmaceutical industries. Thus, understanding the interface which is controlling
Climate change has become one of the greatest concerns of the 21st century as its ramifications pose a major risk to all life on earth. However, not all individuals are aware of this risk and behavioral engagement to counteract the issue is often still lacking. This research examined the relationship between climate change risk perception and pro-environmental behavior. The aim of this cross-secti
The conflict between climate and economic development is one of the most significant dilemmas of this era. Under the prevalent discourse of sustainable development and green economy, many believe that environmental problems can be addressed through market-based approaches under the current capitalist economic regime (Waters, 2008). The purpose of this thesis was to analyze the case of Ant Forest,
