In marked contrast with the ideal error-free feedback assumption that is common in the literature, practical systems are likely to have severely bandwidth-limited, error-prone feedback channels. We consider the scenario where feedback from the receiver is used by the transmitter to select the best antenna, out of many available antennas, for data transmission. Feedback errors cause the transmitter
This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. One approach to achieve flexibility in the run-time scheduling of control tasks is feedback sched
Extraction and chromatographic separation of fat-soluble vitamins is a challenging task, due to the sensitivity of these compounds towards light, oxygen, heat and pH. In light of this, supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC) are attractive techniques as they function at considerably milder conditions than conventional solvent-based analytical techniques. M
Biosensors, combining a selective biological recognition element and a sensitive transducer, are versatile analytical tools applied more and more in different fields, such as medicine, food quality and safety control, and environment pollution monitoring. They are expected to play an increasingly important role in the improvement of life quality. In this context, the present work covers recent app
Mänskliga attityder är fundamentala för att bevara jordens ekosystem. Denna studie undersökte sambandet mellan mänsklig empati och upplevelsen av samhörighet med naturen, mer specifikt, med specifika växter. Undersökningen baserades på enkäter och den statistiska analysen gjordes med rmANOVA. Deltagarna (N = 106, medelålder =32,7 SD =16,0) bedömde sin empati och upplevelse av samhörighet med naturHuman attitudes toward nature are fundamental for preserving earth’s ecosystems. This study investigated the malleability of human empathy and connectedness to specific plants. We randomly assigned participants (N = 106, Mean age = 32.7, SD = 16.0) to one of three different induction conditions, and measured trait general empathy and connectedness to nature, as well as state empathy and connectedn
Bosnia and Herzegovina has been one of the countries in the Western Balkans mostly affected by terrorism and the phenomenon of foreign terrorist fighters, which it has had a hard time combating. The country has been on the agenda of EU integration for many years, a process which has taken a very long time, but has in recent years accelerated rather drastically. There are many theories about terror
As supply uncertainties and increased lead times were more prominent than ever during the covid-19 pandemic, many companies experienced disrupted supply chains and realized the weaknesses in their inventory management and supply chain planning. Many organizations, including the case company in this thesis, Beijer Ref, experienced the impact of the bullwhip effect on their operations. The bullwhip
Adsorption is an important separation technique in chemical engineering, capable of achieving a high purity of product. As it is also capable of concentrating even very low concentrations it was investigated as a possible method to concentrate the product of an ammonia plasma reactor in the EU DARE2X project. As the development of adsorption systems is expensive and time consuming, a simulation of
PFAS is a group of long-lasting chemicals with multiple known toxicological effects which has been found everywhere in nature. One of the possible source points of PFAS is via landfill through leachate leaving the area. It is therefore important to investigate and implementing remediation techniques to reduce the contamination risk. This thesis focuses on two components, first a literature study w
Early designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin
Modern medicine is rapidly evolving toward personalized treatments, where therapies are tailored to an individual’s genetic profile. This shift is driven by the promise of pharmacogenomics, which aims to match patients with the most effective medications based on their unique biological makeup. As a result, biotherapeutics made from biological sources like proteins, peptides, and antibodies are be
This thesis investigates the integration of the individual learning rates from Rprop into SGD and Adam optimization methods. The individual learning rates are updated separately from the weights. A major focus of this work is the role of mini-batch size in updating these learning rates. Empirical analysis demonstrates that selecting an appropriate mini-batch size can accelerate convergence and imp
Glioblastoma (GBM) remains one of the most aggressive and treatment-resistant brain tumors, with limited systemic therapeutic options and high recurrence rates. New treatment modalities in oncology, including antibody-drug conjugates and CAR-T cells, target the tumor cell surfaceome. However, despite extensive genomic and transcriptomic profiling, actionable surface antigens for targeted immunothe
This master thesis analyses the effectiveness of smart beta strategies in improving the returns of index funds within the Nordic and Baltic regions. The study employs a mixed-method approach, combining qualitative literature review with quantitative empirical analysis of historical market data, focusing on key stock indices in Sweden, Denmark, Finland, Iceland, Norway, Lithuania, Latvia and Estoni
Biomanufacturing increasingly relies on computational modeling to strengthen process understanding, speed up process development, scale-up and scale-down, improve experimental design, and reduce reliance on costly and laborious wet lab activities. Here we present CADET-Hub, a modular web-based platform for biomanufacturing and stability modeling, developed within the Inno4Vac project. CADET-Hub un
Problem discussion: To be competitive in a changeable environment, as the video surveillance market, in a time when the company and the market grow with almost 40% yearly, the sales organization must be well trimmed and effective. Knowledge about customers’ needs and what makes success are essential parts of the progress. Sales Product Management (Sales PM) is a new group at Axis with the main tas
Cell reprogramming technologies have enabled the generation of various specific cell types including neurons from readily accessible patient cells, such as skin fibroblasts, providing an intriguing novel cell source for autologous cell transplantation. However, cell transplantation faces several difficult hurdles such as cell production and purification, long-term survival, and functional integrat
Using the configuration interaction technique, the energy spectra of 2s(2)2p(4), 2s2p(5), 2s(2)2p(3)3s, 2s(2)2p(3)3d, configurations of oxygen-like chlorine Cl X have been calculated. The obtained data are used for the evaluation of wavelengths and oscillator strengths of all possible one-electron and two-electron 2s(2)2P(3)3p-2s2p(5) electric dipole transitions. The calculated results are compare
