The classification of toxic comments is a well-researched area with many techniques available. However, effectively managing multi-label categorization still requires a considerable amount of work. In this thesis, we performed a classification experiment on over 200 thousand comments from the Jigsaw toxic comment competition data available on Kaggle. We aimed to optimize a model to identify six di

This project covers the increasingly growing problem of in-car driver distraction due to infotainment systems. The purpose was to understand this topic and variables, like size and user flows, that lead to distraction and then implement a solution in Spotify ́s Apple CarPlay application. This to combat this problem by providing the user with greater usability in terms of starting music playback. A

The present thesis investigates motion-emotion metaphors in Estonian and compares them cross-linguistically with Finnish, English and Swedish. Motion-emotion metaphors (e.g. I fell into depression) are expression types that denote affective responses, which imply conspicuous bodily changes, using motion verbs and other linguistic expressions that typically express actual motion. Metaphor has been

The topic of this thesis is to identify a surface with robot force control. To achieve this a robot performing contact force control on a surface while it also follows a trajectory is needed. All experiments were performed in the robot laboratory at the Department of Automatic Control at Lund Institute of Technology. The robot used was an ABB Irb-2000 robot, equipped with a wrist mounted force and

Enligt högskoleförordningen kan universitet och högskolor I Sverige vidta disciplinära åtgärder mot studenter som fuskar. Reglerna kräver dock att en student ska ha begått handlingen med uppsåt för att ansvar ska kunna utkrävas. Endast oaktsamhet kan således inte utgöra en grund för att vidta disciplinära åtgärder mot en student. Trots att ett stort antal studenter varje är blir föremål för discipThe Swedish governmental ordinance for higher public education, Högskoleförordningen, allows universities in Sweden to take disciplinary measures towards students that are found cheating. However, the rules require that the cheating actions of the student has been committed either intentionally or knowingly in order for them to be held responsible. Simple negligence is thus not an allowed reason t

For some time now “Rondellen”, a roundabout just outside Folkets Park in Malmö, has been a place where drug transactions are taking place out in the open street. Buyers know that sellers will be there for a quick and easy transaction in a central part of Malmö. But why are the transactions taking place just there? A lot of people are passing by who can watch them trade or the police can come aroun

This master thesis is part of the development of a new industrial machine. The machine is a fully automated transplanting machine for the forest industry and will be used by nurseries around the world. Nurseries grow seedlings and sell them when they have grown enough to be planted in the ground. The machine being developed moves plants from a tray with small cells to a tray with bigger cells. Thi

CFD simulations of direct gas injection, especially in large dual-fuel engines, can be expensive both regarding time and computational power. The nozzle area needs to be resolved with a fine mesh to capture all phenomena and for a full engine model this results in a large amount of cells. A method using a Lagrangian Particle Tracking (LPT) approach was developed to handle gas injection by injectin

By recirculating exhaust gases to the gas turbine inlet a temperature rise and hence, a density reduction, is achieved at the compressor inlet. For a constant volume flow this results in a reduced mass flow, ultimately affecting the temperature of the flame, and the emissions, at part load. This study is conducted by creating a model of the Siemens twin shaft gas turbine SGT-750 in the software IP

Popular science This study describes the development and implementation of a Photo Voltaic (PV)Roof Integration Analysis Tool integrated into a GIS system in order to be used in conducting research within alternative energy field. This study focuses on the Dokki district in Greater Cairo that was used as a case for developing the idea of a tool to assess the possibility of the roofs of existing bu

In a globalized world, schools are becoming more diverse. Research has shown that feelings of belonging are important for the success of migrants in school. Mostly quantitative research has been carried out, however, and it has shown a relationship between belonging and educational achievement, academic motivation, and health-related issues. For this thesis, I use previous research as a stepping s

In the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade

This report depicts the design development of a modular tool used in the creasing process of packaging material. The aim of the new design is to decrease the setup time while at the same time increase the degree of customization to create new packaging designs for small series production which is difficult with the current tool. Multiple design concepts for the new tool were generated from explori

Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. Cellular Internet of Things (IoT) is expected to ma

Det finns idag många olika lösningar för att mäta fluidflöden. För att uppnå hög precision i mätningarna blir sensorernas tillverkningskostnad ofta hög och deras principer är generellt baserade på avancerad teori. I det här examensarbetet undersöks en ny mätprincip, baserad på konceptet för en vanlig rotameter. Den nya mätprincipen använder en solenoid för att skapa ett magnetiskt fält som håller Fluid flow measurement is a task for which many different solutions exist. For high precision sensors the production cost is high and measurement principle is generally based on advanced theory. In this thesis a new principle of fluid flow measurement, based on the concept of a conventional rotameter, is investigated. The new principle uses a solenoid to create a magnetic field to maintain a float

In this master thesis an equipment for measuring the quality on various grains within the agricultural industry is being investigated. The equipment is manufactured by FOSS Tecator a company situated in the beautiful city of Höganäs in Sweden. The food-analyzing is conducted with so called NIR-spectrometry, a method in which the grain is exposed to light with various wavelengths. The different wav
