Pretrained language models are integral part of AI applications, but their high computational cost for training limits accessibility. Initiatives such as Bloom and StarCoder aim to democratize access to pretrained models for collaborative community development. Despite these efforts, such models encounter challenges such as limited multilingual capabilities, risks of catastrophic forgetting during
The practical application of aqueous rechargeable batteries faces several challenges due to the limited stability window of electrolytes and parasitic side reactions, such as corrosion, passivation, gas evolution, and co-intercalations. The solid electrolyte interphase (SEI) formed at the electrode/electrolyte interface plays a critical role in determining interfacial properties and battery perfor
A decentralized strategy for object transportation is presented, assuming that the object is grasped by a team of N cooperative manipulators. The proposed strategy consists of two steps. First, each robot estimates the wrenches applied to the object by all the others robots, even without all-to-all communication. Second, an admittance control scheme is used to limit internal wrenches, preventing e
This special issue introduction explores dialogic organizing centred on affirming public engagement for hope and solidarity. We propose ways of retheorizing and revitalizing dialogic perspectives and practices. In so doing we take our cue a Bakhtinian understanding of dialogue; however, we suggest that it is necessary to move beyond this foundational understanding. Instead, it needs to be read in
The HIBEAM-NNBAR program is a proposed two-stage experiment at the European Spallation Source focusing on searches for baryon number violation processes as well as ultralight dark matter. This paper presents recent advancements in computing and simulation, including machine learning for event selection, fast parametric simulations for detector studies, and detailed modeling of the time projection
We report 23 lichenicolous fungi new to Sweden, among these, one is new to Europe, 21 are new to Fennoscandia, and two are newly reported for Norway. This article focuses only on mitosporic fungi. The newly reported species are Acremonium pertusariae, Cladophialophora dimorphospora, Cladosporium licheniphilum, Corynespora laevistipitata, Didymocyrtis cladoniicola, D. grumantiana, Ellisembia lichen
The rate of change in adaptive laboratory evolution (ALE), in which a population of microorganisms is continuously cultivated under a specific selective pressure, is controlled by the cellular mutagenesis rate and the randomness of where in the genetic material mutations are introduced. The constant selection pressure makes it a crucial, yet slow, method in developing microorganisms with novel phe
Education is by the UN stated to be the foundation to creating sustainable development. Lately, there has been a tremendous increase in the use of information and communications technology (ICT) for educational purposes worldwide, but as many countries lag behind both in terms of uptake and usage of ICT, this limits their populations’ chances to participate. Given this, the aim of this thesis was
While perovskite solar cells have become increasingly more efficient and popular, electrical characterisation of the semiconductor properties of perovskites has been limited due to the instability of the material. In this work, multiple approaches for creating such electrical test structures from perovskites are discussed. The chemical processing limitations for perovskites are laid out and common
Thin-Film Transistor (TFT) technology refers to process and manufacture transistors, circuits, Integrated circuits (ICs) using thin-film organic or metal-oxide semiconductors on different substrates, such as flexible plastic foils and rigid glass substrates. TFT technology is attractive and used for applications requiring flexible, ultrathin ICs to enable seamless integration into devices. TFT t
In the last 30 years, a new mobile communications generation has been developed every 7 to 10 years. The last one that is currently under development is the Fifth Generation. This generation aims to fulfill a wide range of requirements for different use cases. To that end, a new radio access technology called New Radio (NR) has been developed. The main design principle behind NR is to allow enoug
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
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
Wireless Power Transfer (WPT) technology has experienced phenomenal success in the application of wireless charging of smartphones. With the Qi Specification becoming the dominant standard, wireless charging's convenience goes beyond cable-free charging to facilitate interoperability between chargers and devices from different vendors. For wireless charging to operate correctly, the power tr
Failure often captures public attention, especially in an intelligence context were the consequences can be devastating and the successes are rarely visible. Understanding failure is important if we are to prevent it and both the field of organizational theory and the field of intelligence have been interested in the nature of failure. This study aimed to further the understanding of intelligence
Polymers of N-substituted glycine (NSG) or as they are also called, peptoids, have shown potential in biomedical applications due to proteolytic resistance, among other interesting properties. In this thesis project, two synthetic routes have been performed and evaluated to achieve a better understanding of large-scale syntheses of peptoids as a bioinert coating for nanoparticles. The primary fo

Since the purchasing expenditure of many companies is such a large part of the total cost and 99,8 % of companies are classified as Small and Medium Sized Enterprises (SME), one might expect that theories on purchasing strategy would not only be conducted for large companies but also SMEs. In order to fill this gap in theory, this thesis aims to create a purchasing strategy framework for SMEs in t
