Auditory attention detection is crucial for understanding speech in noisy environments, a challenge known as the "cocktail party problem." This project investigates the use of electroencephalography (EEG) to identify which speaker a listener attends to. EEG’s portability and real-time recording capabilities make it a promising tool for practical applications. We propose a novel neural n
Options play a significant role in the financial market. The pricing of the options is a prevailing topic in academia. The Black and Scholes (Black & Scholes, 1973) model, on the one hand, was applauded by its simplicity and ease of use, on the other hand, it was criticized by the practitioner and academics because of the over-idealized constant volatility and underlying distribution assumptio
Vulkanisk aktivitet har sedan längre observerats ha en stor påverkan på klimatet. Svavelaerosoler från utbrott bildar molntäcken som kan sprida sig runt globen och hindrar en del solstrålar från att nå markytan. Till följd av detta sker en temperaturminskning av marknära luft under det område som molnet täcker. Den här kandidatuppsatsen reder ut skillnaden mellan inverkan på klimatet samt atmosfär
Följande studie har ämnat undersöka i vilken grad beteendefrekvens förväxlas med uppfattad kompetens, samt ifall ansvarsutkrävande (accountability) kan ha en påverkan på sambandet. Följande hypoteser bildades: H1: Individer som exponeras för hög beteendefrekvens kommer att tillskriva högre kompetens till den bedömda personen jämfört med individer som exponeras för låg beteendefrekvens. Samt, H2: DThe following study aimed to explore the extent of which behaviour frequency is confused with competence, and furthermore if the manipulation of perceived accountability has any effect on the relationship. From this, the following two hypotheses were formed, H1: Individuals exposed to high behaviour frequency will attribute higher competence to the person being judged, compared to those who are ex
In 2023, Russia invaded Ukraine and began an occupation of large parts of the country. This invasion sparked concern in many nations and led to an increased interest in defence issues, thereby triggering a narrative of rearmament. A major focus within this rearmament narrative is the drone, which, in the midst of the war, became a game changer for both the Russians and the Ukrainians. The drone is
The political landscape is in a constant state of transformation. Today, the political map is being redrawn, with pronounced shifts to the right. Parallel to this development, the public administration is expected to adapt to these shifts. This development raises questions about how changing political power dynamics influence politicians' perception of the civil servants. This thesis aims to e
The discrete Bak-Sneppen model is a Markov chain describing the co-evolution of n species arranged in a one-dimensional circular lattice with periodic boundary conditions. Each species i at time t is assigned a fitness value xi(t) ∈ {0,1} and the system evolves through local interactions: at each time step, a species with fitness 0 is selected, and its fitness—along with that of its two neighbors—
Although remote video communications are prevalent, they lack some natural aspects of usual human interactions. To an extent, these aspects can be reintroduced by immersive technologies and human digital representations, the avatars. A commonly occurring challenge faced by such Extended Reality applications is communication between dissimilar spaces, i.e. spaces with different layouts. In such la
This bachelor thesis studies a specific recurring trend from the 1990’s, which in this case is exemplified as dungarees, or as more commonly used, overalls. To understand the essence of this trend and why it’s recurring, a semiotic analysis is applied to the study and to understand the qualitative values it houses, such as social practices and structures, as well as signs, codes and symbolism, wil
