6. Detecting bark beetle damage with Sentinel-2 multi-temporal data in Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : The European spruce bark beetle is considered as one of the most destructive forest insects to Norway spruce trees in Europe. Climate change may increase the frequency and intensity of bark beetle outbreaks. It is therefore of vital importance to detect the bark beetle outbreaks and take it under control to prevent further damages. LÄS MER
7. Unbiased pitch detection and phase estimation in entomological lidar
Master-uppsats, Lunds universitet/Matematisk statistikSammanfattning : Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained.

8. Bioinformatic approaches for detecting homologous genes in the genomes of non-model organisms : A case study of wing development genes in insect genomes
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/EvolutionsbiologiSammanfattning : Identifying homologous genes, that is genes from a common ancestor, is important in comparative genomic studies for understanding gene annotation and the predicted function of a gene. Several pieces of software, of which the most well-known is BLAST, have been developed for identifying homologues, but this can be challenging in non-model organisms where sometimes poor quality of genome assemblies and lack of annotation make it difficult to robustly identify homologues.

9. Miniaturization of a Low Power Harmonic Radar for UAV use
Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknikSammanfattning : The aim with this Master thesis work is to design, build and test a small size, light weight and low power consumption harmonic radar system that will be installed in a flying drone for the purpose of tracking and localizing tagged Bogong moths near their aestivation caves and crevices in Australia during summer. A FMCW harmonic radar is proposed, it comprises a radar transmitter, receiver and a signal processor. LÄS MER
10. Unbiasing entomological kHz Scheimpflug LIDAR data
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/FörbränningsfysikSammanfattning : Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time. Insect observations can be distinguished from the background signal through adaptive thresholding. LÄS MER
