This doctoral dissertation presents a study of linear radio transmitters based on the combined analog locked loop universal modulator (CALLUM) approach. Linear architectures such as CALLUM are very attractive for power-efficient operations, since they have no fundamental limitations prohibiting a 100% efficiency for all envelope levels, without sacrificing the potential of a linear transmission. T

This publication presents a model that describes the lifetime of a tool when used for cutting work in strain-hardened material. The model is known as the Shortcut-Wear-Model (SWM) and can be com-pared with the established model based on Colding equation. The extent of this work has been limited to the turning of the nickel-based alloy 718 with fibre reinforced ceramic cutting tools. This model has

For centuries antiquarians and archaeologists have tried to reconcile the terminology of ancient writers on architecture, such as Vitruvius, with the perceived realities of the material record. One particular issue of debate concerns the interpretation of different words for "brick" in Latin. In this paper it is argued that earlier attempts to settle this question are unsatisfactory and leave seve

This manuscript presents simulation results of energy dissipation in sub-threshold (sub-VT ) of various 16-bit adder structures. The architectures designed for the comparative experiments are, a bit-serial, an 8-bit digit-serial and a 16-bit parallel adder structures. The designs are synthesized in a 65 nm low-leakage high-threshold CMOS technology. The results show that an energy minimum operatin

The present thesis constitutes a close study of a single architectural monument, the tomb of Caecilia Metella. This is a well-preserved cylindrical tomb situated on the Via Appia outside Rome, and it is generally associated with sepulchral buildings of the traditional tumulus type. An inscription reveals that the occupant of the grave was a noble woman belonging to one of the most prestigious fami

Whether the Ganges river in Varanasi (India) is pristinely pure or heavily polluted depends on by whom it qualities are defined, the Brahmin religious specialists in the city or the science oriented environmentalists. While the controversy continues, some Hindu religious leaders are searching for ways to adjust their respective traditions to the environmental paradigms, an initiative that reflects

The aim of this study was to examine how an organisation’s approach to brands can, in the building up of a brand competence, prevent trademark degeneration and develop and protect brands as strategic resources. A line of argument is put forward for adopting a new corporate approach (mind-set) to brands. The starting-point is the concept of trademark degeneration (genericness), which is both the ke

This dissertation in anthropology of religion focuses on images of Tibet, among Westerners as well as among Tibetans. Based on approximately one year of fieldwork in the former British Hill station, it also deals with the politics of the Central Tibetan Administration (CTA) and some of its political and social implications for the exiled Tibetan youth living in Dharamsala, India. The Western perc

The aim of the study is to improve on the understanding of the implications for adolescents of being placed in foster care. The basis for the study is that the adolescents´ previous relationship with their parents has significance for the manner in which the adolescents will handle the separation from the parents and how they will relate to foster parents. 27 adolescents aged 13-16 years were exam

It is difficult for states to cooperate on issues related to international peace and security. Yet, ever since 1970, the EU member states have succeeded to gradually intensify their foreign policy cooperation and increasingly act in unison towards the rest of the world. This PhD thesis seeks an explanation to this trend. It does so by initially painting a picture of when, in time, the volume and c

The drying of a porous material occurs in two different periods: the constant rate period and the falling rate period. During the constant rate period, the drying rate is determined by the external conditions regarding heat and mass transfer, and the drying rate is not influenced by the properties of the drying material. During the falling rate period, the material properties, such as the transpor

My study focuses on the analysis of single poems chosen as paradigmatic of Fole Isaksson's style and poetic vision. This approach is grounded in the belief that there is a certain thematic unity to Isaksson's lyric output, a unity which stems from the poet's constant preoccupation with the relations between the speaker of a poem and external nature, i.e. the place or landscape in or before which t

In this thesis existence and uniqueness of limit cycles are shown for a resonant converter, by extending Poincaré-Bendixson theory to non-smooth vector fields. We discuss relevant control theory and the role of simulations.

The main objective in the research described in this thesis was to design and test the use of lean premixed combustion using combustion gas recirculation for gas fuelled Stirling engine combustors. A system using a flame-arrester type of flame-holder to stabilize the flame and an ejector system for the recirculation of combustion gas was designed and tested in the laboratory. The impact of changes
