This thesis reports on the design, fabrication, and testing of state-of-the-art, high-performance inverted top-emitting organic light-emitting diodes (OLEDs). The vast majority of research reports focuses on a device architecture referred to as a conventional OLED which has its anode on the bottom of the device and its cathode on the top. Moreover, most conventional OLEDs are bottom-emitting such that light exits the structure through both a semitransparent bottom electrode of indium-tin oxide and a glass substrate. The particular device architecture developed in this thesis is one in which the devices are inverted (i.e. their cathode is on the bottom as opposed to on top) and top-emitting. Despite the advantages that inverted top-emitting OLEDs possess over conventional bottom-emitting OLEDs, their development has been relatively slow. This is because inverted OLEDs have traditionally been hampered by the difficulty of injecting electrons effectively into the device. In this work, a novel method of injecting electrons from bottom cathodes into inverted OLEDs is discovered. In several previous reports, bottom Al/LiF cathodes had been used with the electron-transport material Alq3 to produce inverted OLEDs, but the resulting inverted OLEDs exhibited inferior performance to conventional OLEDs with top cathodes of Al/LiF. A new route for the development of highly efficient inverted OLEDs is shown through the use of electron-transport materials with high electron mobility values and large electron affinities. After systematic device optimization, inverted top-emitting OLEDs are demonstrated that currently define the state-of-the-art in terms of device efficiency. Optimized green and blue inverted top-emitting OLEDs are demonstrated that have a current efficacies of 92.5 cd/A and 32.0 cd/A, respectively, at luminance values exceeding 1,000 cd/m2. Finally, this discovery has enabled the development of the first stacked inverted top-emitting OLEDs ever made, combining all of the advantages offered by an inverted architecture, a top-emissive design, and a stacked structure. These OLEDs have a current efficacy of 200 cd/A at a luminance of 1011 cd/m2, attaining a maximum current efficacy of 205 cd/A at luminance of 103 cd/m2.

Over the last few years, there have been striking developments in wearable computing. Among all the different forms of wearable devices, Head Mounted Displays (HMDs) are deemed the first seamless solution to enabling workers with real time contextual information and allowing companies to integrate with existing back-end systems. The hands-free feature that come along with the HMDs is also believed a great advantage over many traditional technologies. However, few studies had discussed the impact of different design characteristics of head mounted displays on task performance. This study aimed to find out how different display positions of Head Mounted Displays may affect the performance of workers performing guided repair and maintenance tasks. A set of car maintenance tasks were performed by 20 participants with task guidance presented at four Display Conditions: above-eye HMD, eye-centered HMD, below-eye HMD and the traditional paper manual. Time and errors were measured and discussed, as well as other user experience related measurements.

Plasmodium vivax Duffy binding protein (DBP) is an essential ligand for reticulocyte invasion making it a premier asexual blood stage vaccine candidate. However, strain-specific immunity due to DBPII allelic variation may complicate vaccine efficacy, suggesting that an effective DBPII vaccine needs to target immune responses to conserved epitopes that are potential targets of strain-transcending neutralizing immunity. Anti DBPII monoclonal antibodies, which were previously characterized by COS7 cell binding assay as inhibitory and non-inhibitory to DBPII-erythrocyte binding, were mapped to DBPII gene fragment libraries using phage display. Inhibitory mAb 3C9 binds to a conserved conformation-dependent epitope in subdomain 3 while non-inhibitory mAb 3D10 binds to a linear epitope in subdomain 1 of DBPII. More definitive epitope mapping of mAb 3D10 was achieved using a random peptide library displayed on phage. Since DBP region II is mostly made up of alpha-helices, we used a randomized helical scaffold library, the Affibody library, displayed on phage, to determine epitope of conformation-dependent antibodies. The immunogenicity of the identified epitopes was evaluated in mice and the immune sera evaluated for binding to DBPII by ELISA and inhibition of DBPII-erythrocyte binding by the COS7 cell assay. Immune serum from the mAb3C9 epitope blocked DBPII-erythrocyte, suggesting this epitope could be a good subunit vaccine target.

ITC/USA 2013 Conference Proceedings / The Forty-Ninth Annual International Telemetering Conference and Technical Exhibition / October 21-24, 2013 / Bally's Hotel & Convention Center, Las Vegas, NV / Images frames have always been used as information source for the Flight Test Campaigns (FTC). During the flight tests, the images displayed on the Head-Up Display (HUD) could be stored for later analysis. HUD images presents aircraft data provided by its avionics system. For a simplified Flight Test Instrumentation (FTI), where data accuracy is not a big issue, HUD images could become the primary information source. However in this case data analysis is executed manually, frame by frame for information extraction (e.g. Aircraft position parameters: Latitude; Longitude and Altitude). In approximately one hour of flight test about 36,000 frames are generated using standard-definition television format, therefore data extraction becomes complex, time consuming and prone to failures. To improve efficiency and effectiveness for this FTC, the Instituto de Pesquisas e Ensaios em Voo (IPEV - Flight Test and Research Institute) with Instituto Tecnológico de Aeronáutica (ITA - Aeronautical Technology Institute) developed an image processing application with pattern recognition using the correlation process to extract information from different positions on the images of the HUD. Preliminary test and evaluation carried out by 2012 using HUD images of the jet fighter EMBRAER A1. The test results demonstrate satisfactory performance for this tool.

This project starts with the idea to develop a game to train people in evacuation drills. The game has to allow people to learn evacuation plans. To do it, the core aspect to be considered is the transfer of spatial knowledge from a virtual environment. Hence in this study, the transfer of spatial knowledge has been evaluated. In particular, the acquisition from a virtual environment has been compared between head mounted display and desktop display. 26 subjects have participated in the experiment. They have been divided in two groups: the first group played the game with a desktop display, the second group played with a head mounted display. The collected data and feedback underline that it is possible to acquire spatial knowledge from a virtual environment, and that participants who used a desktop display obtain more nformation than participants who used head mounted display.
