  1. 6. Unbiased pitch detection and phase estimation in entomological lidar

    University essay from Lunds universitet/Matematisk statistik

    Author : Johan Fogelmark; [2019]
    Keywords : Entomological lidar; wing beat frequency estimation; phas; Mathematics and Statistics;

    Abstract : 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.

  3. 7. Bioinformatic approaches for detecting homologous genes in the genomes of non-model organisms : A case study of wing development genes in insect genomes

    University essay from Uppsala universitet/Evolutionsbiologi

    Author : Lauri Mesilaakso; [2019]
    Keywords : bioinformatics; homology detection; exonerate; BLAST; non-model organisms; homologous genes; wing development genes;

    Abstract : 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.

  4. 8. Miniaturization of a Low Power Harmonic Radar for UAV use

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Saleh Aljaser; [2019]
    Keywords : Harmonic; Radar; Insects; Tracking; Detection; UAV; FMCW; Small; Low Power; Wireless; Communications; Technology and Engineering;

    Abstract : 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. READ MORE

  5. 9. Unbiasing entomological kHz Scheimpflug LIDAR data

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Alexandra Andersson; [2018]
    Keywords : Entomological LIDAR; Insect detection; Wing-beat frequency; Unbiasing of analysis model; Physics and Astronomy;

    Abstract : 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. READ MORE

  6. 10. Insect Event Extraction in LIDAR Images using Image Analysis and Convolutional Neural Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Ludvig Malmros; [2018]
    Keywords : Image analysis; Machine Learning; Mathematics and Statistics;

    Abstract : Insect monitoring has earlier been a manual, tedious and time consuming task that is impossible to do in real time. Thus there exists a need for a real time automatic insect monitoring system for counting and classifying insect for use in scientific research and pesticide spraying control. READ MORE
