This thesis concerns the evaluation of cost functionals on H2 when designing optimal controllers using finite Youla parameterizations and convex optimization. We propose to compute inner products of stable, strictly proper systems via solving Sylvester equations. The properties of different state space realizations of Laguerre filters, when performing Ritz expansions of the optimal controller are
Multiple modern methods of statistical feature extraction and machine learning are applied to classification of encoding and retrieval of episodic memories using electroencephalogram (EEG) recordings. Raw data, different time-frequency methods, and multiclass common spatial patterns are used for statistical feature extraction. For each type of feature extraction multiple machine learning algorithm
The issue of thin capitalization has risen in importance in recent years, to the point that it warranted international action. That action came in the form of Action 4 of the OECD BEPS Project, of Article 4 of the EU ATAD and of the new interest deduction limitation rules in the national Swedish legislation. The main part of the chosen rule in all these instances disallows interest deduction over
Sedan 1970-talet har antalet rapporterade cancerfall dubblerats, dels på grund av förändrade levnadsvanor och dels på grund av bättre screeningmetoder som upptäcker cancern i tidigt skede. Tidig upptäckt av cancern i kombination med utvecklad cancerbehandling har bidragit till att risken för att avlida av cancer har minskat. Cancerbehandling sker huvudsakligen genom operation, strålbehandling elle
Every day more devices all over the world are connected to networks. Some of these devices have microphones that could potentially be used in a networked array. This opens up the possibility to determine where sounds in the environment are produced, given the positions of the microphones are known. This thesis investigates the feasibility of using a number of network connected speakers with built-
This thesis examines what barriers and opportunities exist for public participation in addressing biodiversity loss and adapting to climate change in Swedish biosphere reserves (BRs). This was approached by conducting an instrumental case study of all seven BRs in Sweden, consisting of semi-structured interviews and a case-specific literature review. The results identified that while a significant
Lignin, the most abundant aromatic polymer in nature, is a valuable renewable resource due to its high phenolic compound content. Utilizing depolymerized lignin for the bioproduction of valuable industrial precursors such as muconic acid has garnered significant attention. In this study, several genetically modified strains of Pseudomonas putida were constructed to bioconvert vanillin and guaiacol
A system for affective touch has been constructed, in a study of humanoid and social robotics. The system detects, processes and analyses signals from touch, identifies touch types, and provides a corresponding emotional response and expression. Touch is detected on an Epi humanoid robot head through the use of conductive paint on the inside on the head shell, and the electrical signal produced is
Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. Topological relationships are for instance relations
Purpose of the study: To further generate an understanding of previous research on NSD challenges in small firms and NSD methods used by firms when developing new experiential services. Theory: Research on challenges faced by small firms with performing NSD and methods experiential service firms use to perform NSD. Methodology: Qualitative multiple case study, the study is deductive in nature. Dat
Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. These unique properties make TB a great candidate as a molecular cleft compound and a good structure as a mo
In Skåne, Southern region of Sweden, where the idea that no Sámis live in the area is largely spread across the Swedish population, the few Sámis living there find themselves navigating their ethnic identity, between performativity, agency, and making use of the policies implemented at a national level. In a context of ongoing decolonisation of the Sámis and their lands, official institutions such
Threat and Error Management (TEM) har framförts som en modell för att förstå, förklara och utbilda i hur olika flygsäkerhetsrisker uppkommer och kan hanteras för att uppnå en ökad flygsäkerhet. Den bygger till stor del på den tidigare utvecklade modellen för övervakning av operationell flygverksamhet, Line Operations Safety Audit (LOSA). Information har insamlats med hjälp av litteraturstudier, in
Modern embedded development flows often depend on FPGA board usage for pre-ASIC system verification. The purpose of this project is to instead explore the usage of Electronic System Level (ESL) hardware-software co-simulation through the usage of ARM SoC Designer tool to create a virtual prototype of a cellular IoT modem and thereafter compare the benefits of including such a methodology into the
Eutrophication caused by nutrients such as phosphorus has become a major issue over the years. Dealing with this phenomenon is a major concern in many countries, and municipalities are establishing strict rules to cope with this problem in water bodies. However, the development of cities has a cost, and supplying the food needs of people is essential. In order to optimize agricultural lands, the u
Interactions between T-cells and other body cells is an essential part of the immune system. It involves the binding between surface receptors of the two cells. Specifically, T-cell receptors (TCRs) bind onto pMHC (peptide-loaded major histocompatibility complex) molecules on the partnering cell surface. This way, a cell signal from the TCR to the nucleus can be initiated. Depending on the "m
With socio-economic hardships arising and dramatically worsening as a cause of the present-day financial crisis, The World Bank has warned against severe cases of brain drain as emigration becomes increasingly desirable to the Lebanese population. Lebanon, already possessing one of the world’s largest diaspora, can be characterized as being one of the largest remittance-receiving countries, where
