  • Assessment of Genetic Relationship of some Horseshoe Bats (Chiroptera: Rhinolophidae) in Vietnam Using Cytochromoxydase Subunit I (COI) Gene Sequence

    • Authors: Tran, Thi Nga; Tran, Thi Thuy Anh; Do, Thi Thanh Huyen; Nguyen, Truong Son; Vu, Dinh Thong; Nguyen, Van Sang; Hoang, Trung Thanh (2016)

  • DNA barcoding was used to examining the genetic relationship between some Rhinolophus bat taxa (R. malayanus, R. cf. malayanus, R. marshalli, R. cf. marshalli) in Vietnam using cytochrome oxidase-I (COI) gene sequence. Through this study, we constructed the phylogenic trees and analysed genetic relationships between some Rhinolophus taxa collected in Vietnam. The obtained phylogenetic tree showed two well-defined clusters. The genetic distances between species varied from 2.7% to 16.3%. The smallest distances were recorded between species from the same group whereas the largest distances were between species from the different groups. Genetic data supported the previous conclusion bas...

  • Design and implement UAV for low-altitude data collection in precision agriculture

    • Authors: Vu, Minh Trung; Nguyen, Truong Son; Quach, Cong Hoang; Pham, Minh Trien (2021)

  • In recent years, along with the development of precision agriculture, Unmanned Aerial Vehicles (UAVs) in crop data collection is becoming more popular because of the advantages of collecting data in a large area. However, many crops and special growing conditions require low-flying UAVs to collect data such as orchards. This challenge with the safety control algorithm of the UAVs. The research aims to develop UAVs capable of autopilot and sampling at low altitudes. The safety control problem of UAV is solved by the Visual Inertial Odometry (VIO) algorithm using a stereo camera synchronized with an inertial measurement unit (IMU). Besides that, the UAV is equipped with a high-resolutio...

  • Design of UAV system and workflow for weed image segmentation by using deep learning in Precision Agriculture

    • Authors: Dao, Duc Anh; Nguyen, Truong Son; Quach, Cong Hoang; Nguyen, Duc Thang; Pham, Minh Trien (2021)

  • Collecting and analyzing weed data is crucial, but it is a real challenge to cover a large area of fields or farms while minimizing the loss of plant and weed information. In this regard, Unmanned Aerial Vehicles (UAVs) provide excellent survey capabilities to obtain images of the entire agricultural field with a very high spatial resolution and at a low cost. This paper addresses the practical problem of the weed segmentation task using a multispectral camera mounted on a UAV. We propose the method to find the ideal workflow and system parameters for UAVs to maximize field crop coverage while providing data for reliable and accurate weed segmentation. Around the segmentation task, we...
