The human brain can be seen as an ensemble of interconnected neurons, more or less specialized to solve different cognitive and motor tasks. In computer science, the term deep learning is often applied to signify sets of interconnected nodes, where deep means that they have several computational layers. Development of deep learning is essentially a quest to mimic how the human brain, at least part
Many microfluidic devices have been developed to separate rare cells, e.g. circulating tumor cells. The collection and analysis of the separated rare cells pose a challenge as it may lead to loss of target cells since extremely small number of cells are usually suspended in a large volume after separation. Here, we present an integrated device that allows acoustophoretic target cell separation and
Context: De novo brain tumors developing after treatment of pituitary/sellar lesions have been reported, but it is unknown whether this is linked to any of the treatment modalities. Objective: To study the occurrence of malignant brain tumors and meningiomas in a large cohort of patients treated for pituitary/sellar lesions, with special emphasis on the role of radiotherapy (RT). Patients and Meth
We develop fixed-point algorithms for the approximation of structured matrices with rank penalties. In particular we use these fixed-point algorithms for making approximations by sums of exponentials, i.e., frequency estimation. For the basic formulation of the fixed-point algorithm we show that it converges to the solution of a related minimization problem, namely the one obtained by replacing th
In object-oriented programs, the relationship of an object to many objects is usually implemented using indirection through a collection. This is in contrast to a relationship to one object, which is usually implemented directly. However, using collections for relationships to many objects does not only mean that accessing the related objects always requires accessing the collection first, it also
Problemformulering: Med sociala mediers stigande popularitet har influencer marketing blivit en relevant strategi för företag att utnyttja. Influencer marketing på Instagram innebär att varumärken använder sig av influencers för att kommunicera budskap till följare och därmed företagets målgrupp. Beroende på hur företag använder sig av sin influencer marketing-strategi kan konsumenters förtroende
Renewable hydrogen can be transported using different hydrogen carriers and modes of transport. Each carrier and mode is associated with different drawbacks and benefits relating to – among other factors – storage density and losses. The forthcoming expansion of offshore wind is likely to be coupled with hydrogen production in some way and there are many different ways that this can be done. Th
Den additiva tillverkningsprocessen och kvalificeringen av komponenter i metall är komplex och tillverkningsmetoden är inte ännu fullständigt förstådd. Syftet med detta examensarbete är därför att förvärva kunskap om kvalificeringsprocesser kopplade till additiv tillverkning i metall och att utveckla en hållbar kvalificering för additivt tillverkade komponenter hos Alfa Laval. KvalificeringsprocedThe process of additive manufacturing and qualification of components in metal is complex, and the manufacturing method is still not fully understood. Therefore, the purpose of this thesis is to gather knowledge of the qualification procedures connected to additive manufacturing in metal and to develop sustainable qualification for additively manufactured parts at Alfa Laval. The qualification pro
Losses and damages from climate change are not just a future risk but already a present reality, and “Loss and Damage” (L&D) as a policy domain has been formalised under the United Nations Framework Convention on Climate Change (UNFCCC), alongside mitigation and adaptation. While climate services currently provide strong support for adaptation and disaster recovery, here we propose that an exp
The R¨onneholm-Ager¨od peatland complex, situated in central Scania, contains numerous archaeological sitesdiscovered since the 19th century. Two sediment sequences were obtained at the Ager¨od peatland to compare thesediment stratigraphy with a previous sequence obtained in 1960 to detect any modern-day changes and toestablish the Holocene environmental development in the area. To clarify the tim
Due to its range-dependent target response, frequency diverse array multiple-input multiple-output (FDA-MIMO) radar systems enable superior detection capabilities as compared with conventional phased-array radars. This paper proposes an incoherent detector for airborne FDA-MIMO radar to detect independent but possibly non-identically distributed fluctuating targets. For FDA-MIMO, variations in the
This presentation brings light on how the materiality of three eHealth solutions affects care and care work. We conducted 92 semi-structured interviews with healthcare workers from the south of Sweden. The analysis of the data was interpretive with focus on the participants’ experiences. By exploring the lived experiences of the participants, we found that all the three solutions (1) changed the b
Objective: To develop a reliable and valid short form of the State Anxiety Subscale of the State-Trait Anxiety Inventory for Children (STAI-CH) in the Environmental Determinants of Diabetes in the Young (TEDDY) study. Methods: A Development Sample of 842 10-year-old TEDDY children completed the STAI-CH State Subscale about their type 1 diabetes (T1D) risk. The best 6 items (three anxiety-present a
Oral assessment is an important method to evaluate the learning outcomes of scientific courses. However,there are certain limitations when oral assessment is applied.One of these limitations, which is not apparent in anonymous written exams, is the existence of biases which could lead to unfair (positive or negative) outcomes of the assessment. This could lead to decreased motivation and sense of
Countries with abundant solar radiation have the potential to invest in simple technologies for deactivation of many bacteria and viruses in medical solid waste. In addition to the traditional Infection and Prevention Control (IPC) measures, these simple technologies contribute to better protection of health care workers in countries with compromised solid management schemes. Monitoring of tempera
