The goals of this project are to investigate the viability of using the MyoTM armband developed by Thalmic labs as a tool for myoelectric control of a hand prosthesis as well as investigate whether the armbands ability to record its spatial position and orientation can be used to increase the performance of the prosthesis control program. Using the surface electrodes, gyroscopes and accelerometers
The present thesis is an investigation about the analysis and study of what is the best way to obtain greater savings of heat principally from the reuse of Drain Hot Water (DWH). The study is carried out through the hypothetical application of one of these heat reuse systems and the installation of renewable solar system to reduce the electricity consume in a single-family house of 300 m2 located
Youth present either a risk or a great opportunity for change. Traditionally youth have been perceived in binary terms of either as victim of wars or as threats to peace and security. The UNSCR 2250 on Youth, Peace and Security presents a shift in the perception of young people, now regarding them as agents of peace and security. This thesis will shed light on young Palestinians through a case stu
Raman spectroscopy is well known as a method that can be used to study the structural characteristics of carbon materials such as soot and carbon black. In this work, a Raman spectroscopy setup was used to record spectra of various carbonaceous samples under different experimental conditions. The wave-number range of interest was from 900 to 3300 cm-1, which includes the first and second order Ram
Tissue-mimicking phantoms are of great interest in the development of bio-medical applications. Instead of applying to biological tissues directly, phantoms enable stable and easy accessibility to validate spectroscopy systems and measuring processes. This thesis project is centered on the development and characterization of phantoms. The interaction between light and biological tissue is mainly
The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. In the conversion between blue light and light of lower energy approximately 25-45 % of the radiant power is lost
In peritoneal dialysis ultrapure water used is produced from tap water by using several filter cartridges in series. One of the cartridges is an ion exchange filter removing cations and anions by either reverse osmosis membrane or chemical ion exchange resin. The ion exchange filter that is investigated in this thesis is a chemical ion exchange filter. The current chemical ion exchange system has
The core objective of this project was to design a controller for a drone (or quadcopter) that would allow the drone to keep a target in the center of a video filmed by a camera mounted on the drone. This was done by controlling the pitch of the gimbal, on which the camera was placed, and the yaw of the entire drone combined with using an image recognition program that could identify the target. F
Materialegenskaper som hållfasthet och duktilitet har historiskt förbättrats genom att materialet modifieras homogent, men även kompositer har vuxit fram som ett vanligt verktyg inom industrin som sätt att förbättra materialegenskaper. En alternativ metod som bygger på att materialets mikrostruktur modifieras heterogent, är harmoniskt strukturerade material. Det består av två olika moder av materMaterials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. Just recently the concept of heterogeneously modifying material micr
The pentadentate ligand 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine was isolated and characterized. Mononuclear iron(II) complexes of the ligand have been synthesized and characterized. Three iron complexes, [Fe(CH3CN)L1][OTf2], [Fe(OTf)L1] and [Fe(Cl)L1][Cl6Fe2O] (L1 = 2-(pyridine-2-yl)-N,N-bis(pyridine-2-ylmethyl)quinoline-8-amine) (OTf = triflate, trifluoromethane sulfonate)
Fibrosis is a process characterized by the accumulation of extracellular matrix components and is attributed to excessive scar formation and is a common feature of many chronic inflammatory conditions. Fibrogenesis involves multiple inflammatory cells including NKT cells, which have been suggested to play a prominent role in the control of this process. Here we characterize a transgenic mouse mode
Plant-insect interactions play a crucial role in the evolution of the coevolving web of life, shaping local interaction networks and moulding the diversity and the evolutionary history of two of the most diverse groups of organisms on earth. The interaction between Lithophragma bolanderi (Saxifragaceae), which presents a geographic mosaic of ploidy levels, and the pollinating floral parasite Greya
This study compares the performance of equal- and value-weighted portfolios using a broad investment universe consisting of the stocks from the Swedish stock market. While implementing random sampling in the portfolio construction procedure, three rebalancing schemes are applied on the equally weighted portfolio in order to observe differences in performance among these. In order to compare how mu
The main purpose of this thesis is to increase the understanding of how hydrogeological conditions are affecting the local water resources in Carrizal on the Barva Volcano, Costa Rica. Hydrogeological investigations of spring characteristics, soil infiltration rates and water flow in springs and rivers were conducted at the study area in Costa Rica as part of a Minor Field Study (MFS). A statistic
Training Generative Adversial Networks (GANs) for image synthesis problems is a largely heuristical process that is known to be fickle and difficult to set up reliably. To avoid common failure modes and succeed with GAN training, one needs to find very specific hyperparameter settings carefully tuned to the model architectures and datasets at hand. Standard GAN training optimization methods such a
Title: Identification and suggestions of emerging technologies for a smart warehouse Authors: Xinchuan Li, Monish Ashok Kumar Background description: The warehouse is a crucial point and one of the most vital logistics and supply chain management links. Warehouses are built to smooth the supply chain and can be divided into different classifications. The importance of warehouses has increased a lo
