Beam-driven plasma-wakefield acceleration is an acceleration scheme promising accelerating fields of at least two to three orders of magnitude higher than in conventional radiofrequency accelerating structures. The scheme relies on using a charged particle bunch (driver) to drive a non-linear plasma wake, into which a second bunch (witness) can be injected at an appropriate distance behind the fir
The water footprint assessment framework aims to illustrate the full impact of water consumption in the whole life cycle of a product, from direct water extraction to water pollution. The framework provides a comprehensive indicator for water resources which, if used with care, can provide detailed information about the different impacts of water consumption in order to aid with water stewardship
This thesis adds the role of the different types of proximity to the discussion on business development. It does so by aiming at start-ups that are currently located in business incubators in the city of Amsterdam, The Netherlands. Current research has focused on the output, effectiveness, diversity, and different types and roles of business incubators. It focuses on what happens within the incuba
This paper investigates the firm and transaction characteristics of PIPE issuers. Whereas previous empirical studies have been focused on the U.S. market, this paper focuses on the characteristics of the European market and also examines the importance of PIPEs as a source of financing and the impact of the institutional settings in key European countries. My findings show that many PIPE issuers a
Policy making processes is under constant study and scrutiny. Different theories bring different dimensions to the table. The Advocacy Coalition Framework (ACF) is especially developed studying ”wicked” problems, which the climate issue without controversy can be called. The ACF studies belief systems among actors, forming advocacy coalitions which act to achieve desired policy outcome. In this st
Hållbar utveckling är ett begrepp som fått ökat genomslag i ljuset av den pågående globaliseringen. Även om det finns flera definitioner till begreppet så innebär hållbar utveckling i sak en strävan efter en varaktig och långsiktig ekonomiskt tillväxt utan att för den sakens skull försaka sociala resurser eller skada naturens ekosystem. Då en allmän uppfattning av globaliseringen är att den bidrarThe notion of sustainable development has gained increased interest due to the on-going process of globalisation. Sustainable development as a concept refers to lasting economic growth that does not deplete social resources or harm ecosystems. As there is a general perception that globalisation brings markets and society ever so close to each other, demands are being raised to hold market actors –
It is well-known that the classical Poisson kernel for the unit disc $\D$ in the complex plane is naturally associated to the Laplacian. In a recent paper Duman has shown that Poisson integrals with respect to the kernel $$ K_2(z)=\frac{1}{2}\frac{(1-\lvert z\rvert^2)^3}{\lvert 1-z\rvert^4}, \quad z\in\D, $$ solve the Dirichlet problem for the unit disc for a certain second order differential oper
In this roundtable we will present three cases of activist music education, in other words innovative and inclusive practices of music education initiated by courageous institutional leaders and teachers in the Finnish and Swedish context. By activism we mean professional thinking and action that strives toward new ways of making change inside and outside educational institutions through four char
Digitally animated characters are promising tools in research studying how we integrate information from speech and visual sources such as gestures because they allow specific gesture features to be manipulated in isolation. We present an approach combining motion capture and 3D-animated characters that allows us to manipulate natural individual gesture strokes for experimental purposes, for examp
Anaplastic thyroid cancer (ATC) is a rare and highly aggressive thyroid malignancy, usually resistant to conventional therapeutic strategies. The prognosis of ATC is extremely poor with a median survival rate of 6 months. Current treatment therapy includes surgical resection in combination with external radiotherapy and chemotherapy. The underlying mechanisms involved in ATC tumorigenesis is under
Accurate prediction of ship speed for given engine power and encountering sea environments is one of the key factors for ship route planning to ensure expected time of arrivals (ETA). Traditional methods need first to compute a ship's total resistance based on theoretical calculations, which are often associated with large uncertainties. In this paper, two statistical approaches are investigated t
We study membership in Lipschitz classes (Formula presented.) for a class of α-harmonic functions in the open unit disc (Formula presented.) in the complex plane. From earlier work by Olofsson and Wittsten we know that such an α-harmonic function u is the α-harmonic Poisson integral (Formula presented.) of its boundary value function f on the unit circle (Formula presented.). We determine when the
Healthy cortical bone tissue is both tough and strong and has a unique ability to resist fracture. One reason is the hierarchical structure of the tissue where toughening mechanisms at all length scales act to slow down or stop a propagating crack. The most potent toughening mechanisms arise at the microscale when cracks interact with the osteonal microstructure and deflect along weak interfaces.
This study focuses on the assessment and selection of applicants for doctoral positions. The empirical data was gathered through a survey among faculty staff at Lund University, Sweden. The findings are also contrasted against the literature within the subject area, which is surprisingly scarce. One interesting finding of the survey is the frequent use of interviews and infrequent use of other ass
This paper raises a principled objection against the idea that Bayesian confirmation theory can be used to explain the conjunction fallacy. The paper demonstrates that confirmation-based explanations are limited in scope and can only be applied to cases of the fallacy of a certain restricted kind. In particular; confirmation-based explanations cannot account for the inverse conjunction fallacy, a
