1. Automated Measurement of Relative HF Antenna Properties using WSPR
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The performance of antennas is an important factor in creating a well performing radio communication channel. Traditionally measuring High Frequency (HF) antennas is an expensive and complicated process. J. Zander[1] proposes an alternative method of evaluating antenna performances in the HF band. READ MORE

2. Computational prediction of cell-cell interactions in the brain-tumour microenvironment
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : Glioblastoma is the fastest-growing, and the most common malignant brain tumour in adults. It is normally treated with surgery and radio- or chemotherapy, but the approximate life expectancy is of 15 months with a high probability of cancer recurring. Therefore, there is a need for decreasing its severity. READ MORE

3. Arbitrary motion Synthetic Aperture Radar
University essay from Lunds universitet/Matematisk statistikAbstract : Syftet med denna avhandling är att utveckla en ny metod för att producera bilder med syntetisk aperturradar (SAR), med utgångspunkt i scenarier med arbiträr rörelse vad gäller radarsensorn. SAR är en väletablerad metod för att skapa 2- eller 3-dimensionella radarbilder, som traditionellt sett antar att radar-sensorns rörelse är linjär och förutsägbar. READ MORE

5. Damage Analysis of Reactive Ion and Atomic Layer Etched Silicon
University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionenAbstract : Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge.
