Abstract:
In the evolving scenario of 5G networks, resource allocation algorithms for the Cloud Radio Access Network (C-RAN) model have proven to be the key for managing ever increasing Capital Expenditure (CAPEX) and Operating Expenditure (OPEX) for mobile networks while ensuring high Quality of Service (QoS). In Chapter 1 a brief overview of the main elements of the C-RAN and of the methodologies that are employed in this work is provided. In Chapter 2, an exact scalable methodology for a static traffic scenario, based on lexicographic optimization, is proposed for the solution of a multi-objective

Abstract:
Current mobile network architecture is facing a big challenge as the traffic demands have been increasing dramatically these years. Explosive mobile data demands are driving a significant growth in energy consumption in mobile networks, as well as the cost and carbon footprints [1]. In 2010, China Mobile Research Institute proposed Cloud Radio Access Network (C-RAN) [2], which has been regarded as one of the most promising architecture to solve the challenge of operators. In C-RAN, the baseband units (BBU) are decoupled from the remote radio units (RRH) and centralized in one or more locations

Abstract:
<p>Det här självständiga arbetet i militärteknik avhandlar huruvida Försvarsmakten, med i huvudsak redan befintlig materiel, genom en teknisk aktiv skyddslösning kan uppnå en förbättrad skyddsförmåga mot indirekt eld. Förmågan som söks är främst avsedd för, men inte begränsad till, att kunna nyttjas för att erhålla ett förbättrat skydd av Försvarsmaktens internationella camper. Därmed utgörs hotbilden framförallt av granatkastarammunition och raketer vilka inom ramen för en teknisk aktiv skyddslösning först måste kunna detekteras för att sen medge förvarning, eller ännu hellre avvärjning, inna

Abstract:
The purpose of this thesis is to study the following problem. Suppose that X,Y are bounded self-adjoint operators in a Hilbert space H with their commutator [X,Y] being small. Such operators are called almost commuting. How close is the pair X,Y to a pair of commuting operators X',Y'? In terms of one operator A = X + iY, suppose that the self-commutator [A,A*] is small. How close is A to the set of normal operators? Our main result is a quantitative analogue of Huaxin Lin's theorem on almost commuting matrices. We prove that for every (n x n)-matrix A with ||A|| ≤ 1 there exists a normal matri

Abstract:
In a recent series of papers, Kumjian, Pask, and Sims have investigated the effect of "twisting" C*-algebras associated to higher-rank graphs using a categorical 2-cocycle on the graph. This work has included a characterisation of simplicity for these twisted C*-algebras in terms of the underlying graphical and cohomological data. In this thesis, we initiate the study of twisted C*-algebras associated to topological higher-rank graphs using groupoid techniques, and we characterise simplicity of these C*-algebras. For each cofinal, proper, source-free topological higher-rank graph, and each co

Abstract:
This thesis is the outcome of a research project undertaken to determine how diet can affect the reliability of rat bone (especially that of Rattus exulans) for accurate radiocarbon analysis. It addresses questions about the reliability of R. exulans bone for radiocarbon dating with respect to the survival of bone in archaeological and natural burial sites, laboratory processing methods, and the extent to which diet influences radiocarbon ages of bone. I have shown that R. exulans bone can return reliable radiocarbon dates, based on bone survival and the efficacy of chemical treatment to remo
