There are two, partially interlaced, themes treated in this thesis; inverse problems of tomographic type and fast and accurate methods for the application of convolution operators. Regarding the first theme, the inverse problem of Doppler tomography is considered and the Doppler moment transform is introduced for that purpose. By investigating the properties of the transform, we prove results reg

We believe in managers and we believe in learning. Not least, we believe in managerial learning. Further, the dominant conception is that managers, through reflection on experience, develop an increasingly sophisticated understanding of their work, which in turn renders increasingly skillful managerial actions. Metaphorically, this learning trajectory can be described as a journey from stupidity t

Abstract Author: Marinette Kindeland Title: School Social Work’s perspective on Promoting Mental Health – to be handled and to handle in the School Dramaturgy Supervisor: Alexandru Panican Assessor: Anna Angelin From the 1980s until today, a doubled number of youths are suffering from mental illness in Sweden. One of the most important institutions that meet and socialize young people, are school

Sammanfattning I svensk rätt finns flera inskränkningar av den personliga avtalsfriheten. Pactum turpe är en av dessa och inskränkning innebär att vissa former av avtal som faller under den inte erhåller rättsordningens skydd. Under denna bestämmelse innefattas avtal som står i strid med lag eller goda seder, varav den senares innebörd är närmast omöjlig att fastslå. För att avgöra om ett avtal fa

To bring your case in front of a court – “Access to Justice” – is something most of us look upon as a human right for the citizens in a state governed by law. But to process in court demands time, knowledge and not least money. To facilitate “Access to Court” there is a possibility for litigants in Sweden to apply for legal aid. The government then (partly) finances the legal help one can be l

The aim of this study is to systematically survey and analyse the Scanian manors’ economic and labour organisational development from the province’s Danish times to the middle of the nineteenth century. In this thesis the various surveys provides some clear results that make it possible to generalise the Scanian estate development. Manors were generally large at the end of the the seventeenth cent

In the present doctoral dissertation an attempt is made to qualify the theorertical assumptions about the marginal characret of the popular sectors of the developing countries. According to these theories, individuals belonging to the populart sectors cannot become fully members of their societies because they lack the attitudinal prerequisites. My argument is that their actions are quite sophisti

This thesis is devoted to the analysis of three important issues in financial economics in general and portfolio selection in particular: the risk measure, estimation risk and time diversification. Besides a short introductory chapter the thesis consists of four empirical essays. In the second chapter, the effect of estimation risk on the efficient frontier in the lower partial moment framework is

Membrane filtration is a very gentle separation technique and can be used at low temperatures. This makes it suitable for liquids that contain micro-organisms and/or are heat sensitive, which is often the case in liquids processed in the field of biotechnology. However, one drawback is that these liquids are often very complex, which is a disadvantage when using membrane technology as it makes the

The aim of this dissertation has been to examine the growth, development, and organisation of the knitting industry in southern Halland during early modern times. This proto-industrial enterprise was conducted primarily via a putting-out system in the goods districts. Wallen's estate in Våxtorp parish played an active role in the enterprise already from an early stage. During the latter half of th

This dissertation is a study of In the Heart of the Country (1977), Waiting for the Barbarians (1980), Age of Iron (1990), Disgrace (1999), Diary of a Bad Year (2007), and Summertime (2009) written by J. M. Coetzee. The aim of the dissertation is to analyze these works of fiction using four postcolonial aspects that function as consistent themes in the novels. The aspects are; the relationship bet

The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. There are several architectures for implementing an ADC, but in the last decade, continuous-time Delta-Sigma mod

The use of enzymes for synthetic applications is an area of increasing interest. Enzymes have been pointed out to be an environmentally friendly alternative to existing chemical methods, as well as making completely new synthetic routes possible. Over the last decades, much focus has been put on the enzyme group oxidoreductases, which can selectively introduce oxygen and hydrogen into molecules. T

The in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone

This thesis focuses on engine system simulation using thermodynamics and chemical kinetic models to investigate the performance and efficiency of Homogeneous Charge Compression Ignition (HCCI) engines for stationary applications. It includes the development of software as well as models for engine, turbocharger, intercooler, inlet and exhaust manifolds, wastegate valve, inlet air humidifier, inle
