With the growing popularity of audio and video communication services on the Internet, network operators, service providers and application developers are becoming increasingly interested in assuring that their services give the best possible experience to the users. Since real-time audio and video services are very sensitive to packet loss, latency and bandwidth variations, the performance of the
The main topic of this thesis is the investigation of small molecules adsorbed on metal surfaces by means of core-level photoemission spectroscopy. The thesis consists of three parts; The first group of papers concerns the effects of internal molecular vibrations on the core-level photoemission spectra. The second and third groups of papers concern more basic adsorption properties, like adsorption
This thesis consists of three essays on VIX futures and options, and deals with issues highly relevant to all financial markets, such as understanding the operation of markets and developing flexible and tractable pricing models for contracts traded in them. It consists of four chapters. Chapter 1 provides a short introduction to the VIX and a brief explanation of how the old and new VIX are cons
Recent years have seen an increasing attention given to wireless Personal Area Networks (PANs), which are typically networks with small transmitter-receiver (TX-RX) separation. The desire for high data rates has led to an interest in deploying multiple-input multiple-output (MIMO) transmission for such systems, but up until this date there exists, to the authors’ best knowledge, no MIMO channel mo
Enzymes are involved in most reactions in nature. They are important both for the understanding of biological life and for reactions of industrial interest, e.g. in the production of artificial fertilizers, the production of biomass or biofuels. Enzymes with one or several metal ions are called metalloenzymes. In this thesis we study three different metalloenzymes, nitrogenase, lytic polysaccharid
Gebel el-Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point. The site is generally known for its many Pharaonic cenotaphs, stelae and the speos of Horemheb, but it was once also the world’s largest quarry. As such it was renowned for its high quality sandstone, and the stone was extracted and transported to all overUpper Gebel el Silsila (Mountain of Chain) is located between Kom Ombo and Edfu on both banks of the Nile where it reaches its narrowest point.

With the emergence of industrial IoT and cloud computing, and the advent of 5G and edge clouds, there are ambitious expectations on elasticity, economies of scale, and fast time to market for demanding use cases in the next generation of ICT networks. Responsiveness and reliability of wireless communication links and services in the cloud are set to improve significantly as the concept of edge clo
Future manufacturing systems need to be more flexible, to embrace tougher and constantly changing market demands. They need to make better use of plant data, ideally utilising all data from the entire plant. Low-level data should be refined toreal-time information for decision-making, to facilitate competitiveness through informed and timely decisions. The Line Information System Architecture (LIS
This paper presents preliminary results for a novel 128-antenna massive Multiple-Input, Multiple-Output (MIMO) testbed developed through Bristol Is Open in collaboration with National Instruments and Lund University. We believe that the results presented here validate the adoption of massive MIMO as a key enabling technology for 5G and pave the way for further pragmatic research by the massive MIM
In this paper, we describe Docforia, a multilayer document model and application programming interface (API) to store formatting, lexical, syntactic, and semantic annotations on Wikipedia and other kinds of text and visualize them. While Wikipedia has become a major NLP resource, its scale and heterogeneity makes it relatively difficult to do experimentations on the whole corpus. These experimentat
The main purpose of this paper is to make the study of spatially coupled turbo-like codes (SC-TCs) more complete by investigating the impact of spatial coupling on the thresholds of hybrid concatenated codes (HCCs). In our previous studies, we introduced some classes of SC-TCs and considered their density evolution (DE) analysis. The obtained results indicated that for a fixed coupling memory, bra
The new-economy encompasses a variety of industries, particularly pharmaceuticals and online-based companies. These may hold strong market positions, or be strong future competitors, despite having low turnover. Where foreclosure techniques to curtail competition are employed, the concentration may result in a long-lasting anti-competitive impact on the market. However, due to low or insufficient
Issue: Does a statistical relationship between OMXS30 and S&P500 plus OMXS30 and DAX30 exist after extreme returns? Is it possible to explain the relationship between OMXS30 and S&P500 plus S&P500 and DAX30 with the chosen economic theories? Purpose: The purpose is to examine the effects on OMXS30 during 6 days after extreme returns on S&P500 or DAX30 are present. These effects wi
Chilli extract is used in the food industry for multiple applications, such as a flavour for hot sauces or spicy chocolates. The demand for organic products has grown in the recent years, while changes in demography make it necessary to obtain and aroma that can fulfil the market needs. Hence, the purpose of this project was to develop an extraction method to obtain an organic and halal chilli ext
The Artificial Intelligence (AI) Act is a relatively new regulation set out in the European Union (EU). It lays out various requirements for AI systems that are placed on the market in the EU. This paper provides a critical and differentiated view of its requirements from a software engineering perspective. A detailed analysis of the legal document shows what requirements are set out for different
Bakgrund Framväxten av hälsoapplikationer som gör det möjligt för patienter att kontakta och kommunicera med vårdpersonal digitalt kan förändra hur patienter ser på sin vård och hur de kontaktar vårdpersonalen (WHO, 2011). Digitala system kan också, utifrån sin design, ge förutsättningar för relationscentrerad vård genom att patienterna ges möjlighet att, i samverkan med vårdpersonalen, vara aktiv
