By recent advancements in information technology and artificial intelligence, the chatbot has become a promising venture to streamline the key business function that is customer support, concurrently as the worry of AI taking jobs are rising. This raise concern that a chatbot adoption in the customer support would be underutilized due to negative pre-implementation attitudes of the workforce and u

The role of public transport in society is crucial, particularly for those who do not have access to alternative transport modes. For public transport to be able to fulfil its societal role, it should not be perceived as unsafe or unhealthy by its (potential) users. Several studies from all over the world have shown that anxiety has increased remarkably during the pandemic, and it is likely to las

Fog and clouds are difficult to predict for meteorologist today. Models have a tendency to show either too much or too little clouds or fog, which can be a problem for people and industries that depend on the weather conditions. Improvements are being done, but errors still occur. One of the problems is that when an improvement is attained, it might only work for one specific season. This happens,

This study aims to examine how women, between the ages 18-30, experience the safety during the usage of the dating apps Tinder/Badoo. The study also aims to examine which possible factors that can comprise the experience of safety during the usage. The reason behind this is based on the wide range that this type of dating has gotten over the past several years. Previous studies have mainly been fo

A system for detecting protein-protein interaction using a bacterial two-hybrid approach, a heterologous expression system in Escherichia coli strain based on adenylate cyclase enzyme reconstitution, was invented twenty years ago (Karimova, et al., 1998, PNAS, 95:5752). Before inventing this system, yeast two-hybrid technology was used for screening putative interaction between either two proteins

The effective width model was introduced to show how the flow was linearly proportional to the effective width on stairwells accounting for the edge effect as well as lateral body sway. In this sense, small increments on the width of the stairwell were proven to increment the flow through it in a linear manner. This same principle is currently applied as part of the background for the hydraulic ca

The thesis purpose is to determine how people’s evacuation performance is affected by carrying weight while performing a stair-climbing motion. The fire safety engineering and physiology fields are merged to increase the knowledge regarding ascending evacuation. A laboratory experiment was conducted, in which participants performed three different sessions; during the first session, participants p

The Internet of Things (IOT) is a fast growing field with new actors constantly joining in. Locations such as farms or remote areas do not always have Internet coverage to access the IoT. This thesis looks at LoRaWAN as an IoT technology and ad-hoc networking to solve this problem. Existing ad-hoc routing protocols such as AODV, HWMP, and ZRP were studied. Based on the study they were evaluated as

Undersökningen syftar till att utifrån en alternativ infallsvinkel analysera utvecklingsbegreppets möjliga bredd och alternativa definition. Utvecklingsbegreppet är under ständig förändring och med bakgrund av milleniemålen är det möjligt att tala om en förändring endast baserad på mätbara faktorer vilket ur flera aspekter anses vara negativt. Utifrån en begreppsanalytisk metod samt ett teoretiskt

Transformer-based sentiment analysis systems have become widespread in automated decision-making, particularly in the field of financial sentiment analysis. These models are easy to implement, inexpensive, and offer state-of-the-art performance in sentiment analysis. However, their rapid and broad adoption calls for careful evaluation of algorithmic bias in such models. Previous research has shown

Straumann® Emdogain® is a protein-based gel used in dentistry for tissue regeneration. Emdogain® contains enamel matrix proteins, which are mainly amelogenin proteins. These are obtained through weakly acidic extraction from porcine tooth buds. Embedded in the enamel matrix is also hydroxyapatite which releases calcium ions. These ions saturate the solution, and the protein extraction halts. An at

Purpose: This thesis aims to investigate how customers’ pre-existing brand loyalty influences their perceptions of four characteristics – Perceived Usefulness (PU), Perceived Ease of Use (PEoU), Perceived Trustworthiness (PT), and Perceived Human-likeness (PH) – of AI chatbots used in customer service. In turn, we strive to examine how those perceptions affect overall customer satisfaction towards

Detta examensarbete utvecklar fram en skräddarsydd prototyp av en tillgänglig kommunal webbplats. Det innebär en kommunal webbplats som är anpassningsbar och lätt att navigera, speciellt för användare som tar hjälp av tillgänglighetsverktyg för att utforska webben. För att kunna ta fram denna prototyp, utvecklades först två prototyper som var nära besläktade. Dessa två prototyper jämfördes sedan This thesis project brings forth a tailored working prototype of an accessible municipal website. This means a municipal website that is adjustable and easy to navigate, especially for users in need of accessibility tools to browse the web. To create this prototype, we first created two separate prototypes that closely resembled each other. These two prototypes were then compared to each other and

In recent years, machine learning models have changed the field of video denoising. Most state-of-the-art models utilize multiple frames as input to denoise a single frame, which limits the temporal context window and often requires more computational power. Another, less explored, approach is to use recurrence to gain a hidden memory state in which temporal information can be stored. While the fo

This thesis explores the potential of generative AI to recreate biological spatial systems, using termite mound structures as inspiration. Termite mounds, known for their unique internal networks and passive climate regulation, feature complex spatial logics that challenge traditional modeling techniques. This project investigates whether diffusion-based generative models can be trained to mimic s

It is a continued open question how there can be an azimuthal anisotropy of high p⊥ particles quantified by a sizable v2 in p+Pb collisions when, at the same time, the nuclear modification factor RAA is consistent with unity. We address this puzzle within the framework of the jet quenching model Jewel. In the absence of reliable medium models for small collision systems we use the number of scatte

During the last two decades, an active line of research in proof complexity has been into the space complexity of proofs and how space is related to other measures. By now these aspects of the resolution proof system are fairly well understood, but many open problems remain for the related but stronger proof system polynomial calculus (PC/PCR). For instance, the space complexity of many standard “
