1. 21. Surface energy modification of metal oxide to enhance electron injection in light-emitting devices : charge balance in hybrid OLEDs and OLETs

   University essay from Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

   Author : Sergio Apicella Fernandez; [2017]
   Keywords : organic; inorganic; semiconductors; OLEDs; OLETs; TFT; stack; thin-film; deposition; spin-coating; thermal; evaporation; process; reactive; sputtering; luminescence; EQE; PEIE; metal-oxide; ZnO; ZnO:N; MoO3; F8BT; Alq3; NPB;

   Abstract : Organic semiconductors (OSCs) present an electron mobility lower by several orders of magnitude than the hole mobility, giving rise to an electron-hole charge imbalance in organic devices such as organic light-emitting diodes (OLEDs) and organic light-emitting transistors (OLETs). In this thesis project, I tried to achieve an efficient electron transport and injection properties in opto-electronic devices, using inorganic n-type metal oxides (MOs) instead of organic n-type materials and a polyethyleneimine ethoxylated (PEIE) thin layer as electron transport (ETLs) and injection layers (EILs), respectively.

3. 22. Automatic detection of issues related to colour vision deficient internet users

   University essay from KTH/Medieteknik och interaktionsdesign, MID

   Author : Joel Ekman; [2017]
   Keywords : Colour vision deficiency; Colour blindness; Colour contrast; Developer tools; Accessibility;

   Abstract : With increasing demand placed on online accessibility, a tool that enables developers to more easily build accessible websites for colour vision deficient (CVD) internet users becomes a crucial consideration. An extension was developed for the web browser, Google Chrome, and issues for CVD internet users were identified. READ MORE

4. 23. Indoor Environmental Quality Audit and Investigation of Ceiling Fans in an Aged Care Facility

   University essay from KTH/Energiteknik

   Author : MICHELLE TOMMOSGÅRD; [2016]
   Keywords : ;

   Abstract : This thesis project involved research into the thermal comfort of the occupants and staff at the Warrigal aged care facility at Warilla, NSW, Australia. An Indoor Environmental Quality (IEQ) Audit has been completed with a focus on parameters of luminance, noise levels, concentrations of CO2, NO2, formaldehyde and CO, and air velocity. READ MORE

5. 24. Mönster-elektroretinografi (PERG) på häst

   University essay from SLU/Dept. of Clinical Sciences

   Author : Linnéa Viklund; [2015]
   Keywords : mönster-elektroretinografi; mönster-ERG; PERG; retina; häst;

   Abstract : Mönster-elektroretinografi (mönster-ERG, pattern-ERG, PERG) är en elektrofysiologisk mätmetod där retinas funktion utvärderas objektivt utifrån de spänningsvariationer som fås vid stimulering med ett mönster, oftast på en bildskärm. Mätningarna av dessa elektriska signaler används för att kunna diagnosticera avvikelser och att hitta var i synsinnet ett eventuellt problem är lokaliserat. READ MORE

6. 25. H.264 VIDEO CODING ARTIFACTS : MEASUREMENT AND REDUCTION OF FLICKERING

   University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

   Author : RAKESH ANIL CHODISETTI; BALA RAMA KRISHNA DASARI; [2014]
   Keywords : H.264; Artifacts; Blocking; Ringing; Flickering; Temporal; SSD.;

   Abstract : H.264 video compression technique is currently one of the most widely used video codec for video compression and transmission. It is very important to maintain the quality of video with compression. Our research work mainly focuses on finding the various artifacts caused in the video due to compression using H. READ MORE
