This thesis focuses on the terminal aspects of massive MIMO systems. Based on the degree of freedom a terminal have in a MaMi, different antenna configurations, transceiver topologies with associated transmission schemes, and the underlying algorithms are researched.The first studied topic concerns multiple-antenna terminals in a massive MIMO system for sub-6 GHz, operated at the center frequency
INTRODUCTION The purpose of this chapter is twofold. First, it aims to provide managers and researchers with a number of concepts and perspectives which are relevant to understanding the evolution of environmental management as a corporate function. Second, in adopting and developing a critical position toward a number of current conventions or common assumptions, it aspires to add something of va
This book is in honour of Professor Anna-Sofia Maurin on her 50th birthday. It consists of eighteen essays on metaphysical issues written by Swedish and international scholars.
AIM: Developing a theory explaining how public health nurses accomplish and adapt counselling in lifestyle habits to decrease obesity in people with mobility disability.DESIGN: Empirical research - qualitative.METHOD: Classic grounded theory with face-to-face interviews, 2017-2018, using inductive approach to understand public health nurses' intervening experiences with obesity patients.RESULTS: T
INTRODUCTION Human resource management (HRM) has an important role to play in corporate environmental management in supporting the success of environmental policies and programmes. Indeed, the sorts of changes advocated in this book are unlikely to succeed without the full support of human resource managers. Equally environmental initiatives and culture change programmes will not succeed without t
If resolving the global environmental cns1s were simply a matter of 'techniques', in other words installing new production technologies, converting to zero-emissions vehicles, using less packaging, changing to 'green' fiscal policies and strengthening emissions laws. then why haven't we already implemented them? The technical principles of a shift to a sustainable society are simple and straightfo
Employing two recently developed X-ray imaging techniques, we investigated methods for observing moisture at different length scales in organic fibers and textiles. Using the coherent diffractive imaging technique of ptychographic tomography, structural features in a single coated wool fiber in both dry and humid conditions were observed at about 200 nm resolution. The reconstructed three-dimensio
In this work we develop a computer-aided diagnosis (CAD) scheme for classification of pulmonary disease for grating-based x-ray radiography. In addition to conventional transmission radiography, the grating-based technique provides a dark-field imaging modality, which utilizes the scattering properties of the x-rays. This modality has shown great potential for diagnosing early stage emphysema and
In order to reduce the current hadronic uncertainties in the theory prediction for the anomalous magnetic moment of the muon, lattice calculations need to reach subpercent accuracy on the hadronic-vacuum-polarization contribution. This requires the inclusion of O(α) electromagnetic corrections. The inclusion of electromagnetic interactions in lattice simulations is known to generate potentially la
We derive short-distance constraints for the hadronic light-by-light contribution (HLbL) to the anomalous magnetic moment of the muon in the kinematic region where the three virtual momenta are all large. We include the external soft photon via an external field leading to a well-defined Operator Product Expansion. We establish that the perturbative quark loop gives the leading contribution in a w
This thesis combines a number of methodologies and measures in order to address the processing of two types of negation (with not and un) in relation to each other and to non-negated affirmative meanings. The four investigations in this thesis target the processing of these meanings at different levels, namely the word level (Study 1) and sentence level (Studies 2–4). In two artificial language le
This thesis is concerned with spoken dialogue and the dynamic negotiation of meaning in English conversation. It serves two aims, one theoretical and the other practical. The theoretical aim is to further our understanding of the kinds of properties that influence the meaning of constructions in spoken dialogue and the role of underlying socio-cognitive processes. The practical aim is to compile a
Grating-based X-ray dark-field contrast is an emerging new imaging modality that is demonstrating particularly high potential for radiography. The signal in dark-field X-ray imaging is determined by small-angle X-ray scattering at structures typically below the spatial resolution of the imaging setup. Thus, this technique not only yields complementary information but also visualizes information th
Denna sammanläggningsavhandling berör beräkningar som behövs för precisionsfysik vid låga energier inom Standardmodellen, särskilt högre ordningars korrektioner. I avhandlingens två första artiklar introduceras beräkningar på ordning p8 i kiral störningsräkning, vilket är en effektiv fältteori för QCD vid låga energier. De sista två artiklarna handlar om myonens anomala magnetiska moment och de haThis thesis concerns higher order calculations needed for precision physics in the low energy region of particlephysics. Of the four papers it contains, the first two introduce calculations at order p8 in the power countingof chiral perturbation theory, which is an effective field theory of QCD at low energies. The remaining twopapers concern the hadronic contributions to the muon anomalous magnet
