1. Exploring the Impact of Pseudo and Quasi Random Number Generators on Monte Carlo Integration of the Multivariate Normal Distribution
Kandidat-uppsats, Lunds universitet/Statistiska institutionenSammanfattning : This thesis examines the effects of pseudo and quasi-random number generators on the accuracy and efficiency of Monte Carlo Integration in the case of the multivariate normal distribution. The study compares the performance of the Mersenne Twister (a pseudo-random number generator) with Sobol and Halton sequences (quasi-random number generators). LÄS MER
2. Evaluating image analysis techniques for ultrasound optical tomography in breast tissue
Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknikSammanfattning : Breast cancer is the most commonly diagnosed cancer in the world today and early detection is crucial to minimize the mortality. ”Ultrasound optical tomography” (UOT) is a method under development for deep tissue imaging.

3. Development of a new SBRT dose planning strategy for thoracic tumours in RayStation
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/RadiofysikSammanfattning : Umeå University Hospital has acquired a new treatment planning system, RayStation, for radiotherapy. It has a different set of dose calculation algorithms that require new planning strategies for stereotactic lung cancer treatments. LÄS MER
4. Optimization of Radiotherapy Treatment Plans Based on Monte Carlo Dose Computations
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Treatment planning plays a vital role in providing good treatment to cancer patients. In order to reach an adequate treatment plan, the algorithm used for simulating the dose in the patient must model the reality well. LÄS MER
5. An Empirical Investigation of The Effect of Proxy Response and The Merits of Its Remedial Measures
Magister-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : In the event of missing data, substitution of data from proxy sources are usually considered a very useful alternative when available to avoid the problem of missingness. Nonetheless, research has also shown that this approach often induces “response bias”. LÄS MER
