We have investigated the possibility of using a curved dipole antenna inside the mouth for the tongue controlled wireless devices in 2.45GHz ISM band. These devices can be interfaced with the wheelchair or the computer used by the paraplegic patients. Two antenna placement positions have been investigated: in front of the teeth and behind the teeth. The investigations were done through the FDTD si
Adaptive techniques such as gain scheduling, automatic tuning and continuous adaptation have been used in industrial single-loop controllers for about ten years. This paper gives a survey of the different adaptive techniques, the underlying process models and control designs. An overview of industrial products is also presented, which includes a fairly detailed investigation of four different adap

Meningsfull förändring har diskuterats i flera studier, med den återkommande frågan om hur den skulle kunna konceptualiseras och bedömas för att identifiera vad som utgör meningsfull förändring och var den uppstår. Tidigare studier har genomfört statistiska analyser baserade på traditionella betygsskalor (d.v.s. PHQ-9) för att bedöma meningsfull förändring. Det finns inga bevis för att tidigare stMeaningful change has been discussed in multiple studies, with the recurring question of how it could be conceptualized and assessed to identify what determines meaningful change and where it occurs. Previous studies have conducted statistical analyses based on traditional rating scales (i.e., the PHQ-9) to assess meaningful change. There is no evidence to be found of previous studies attempting t
With increasing pressure to get rid of the world’s dependence on fossil fuels to reach the world’s climate goals, the use of alternative fuels for propulsion are needed. This is a challenge for the maritime industry, where ferries have good properties to become renewable by the usage of batteries. Their routes are mostly fixed routes and with good infrastructure established at each stop, fully bat
Reco Port AB is a company that builds folding garage doors and is a part of the ASSA ABLOY group. Reco uses Styrofoam as insulation in their doors and their current solution of cutting the Styrofoam is using a plunge saw and a custom built table to hold the Styrofoam in place. The solution is not ergonomic and spreads a lot of debris of Styrofoam around the workstation. Due to this it was requeste
Today, most software systems are event-driven, meaning that code execution is triggered by events handled dynamically. A typical example is a graphical user interface, where a button click initiates a specific action. In contrast, classic automation systems rely on programmable logic controllers, which execute code periodically at fixed intervals. The purpose of this study is to compare periodic a
The existing Power Supply Unit (PSU) at Axis Communication contains a fully discrete solution that lacks flexibility for future updates. This research aims to address critical challenges by exploring methods to enhance speed, reduce PCB area, and introduce flexibility to the existing hardware solution. The approach involves replacing hardware functionalities within the control unit with software-c
The aim of this bachelor degree project is to design a modular luminaire with a longer lifespan, in order to reduce consumption. The project aims to explore how design can contribute to sustainable development by creating a durable and adaptable lighting solution. The luminaire is versatile and can either be hung from the ceiling, mounted on the wall, or placed on a table. It can be expanded
The efficiency of combustion engines is crucial for their future development, prompting researchers to explore various factors to enhance performance. Among these factors, exhaust gases hold significant potential. Typically, exhaust gases carry about 30-40% of the engine's energy, which often remains underutilized. Although technologies like turbochargers have made progress in recovering some
Digital integrated circuits are fundamental to modern electronic devices, with increasing design complexity requiring robust verification methods to ensure error free functionality. This thesis examines the critical role of formal verification in digital Integrated Circuits (IC) design, particularly during the architecture modeling phase. Using a state machine module that controls clock frequency
