DIVING INTO DIMENSIONS: EXPLORING THE FEASIBILITY OF 2D DIRECTION FINDING WITH A MULTI-ANTENNA PHASE INTERFEROMETER
Xiaojie Y Wang
In the radio direction finding system, direction finding methods of Phase Interferometer have been widely applied, but because of its direction finding ambiguity, there is a contradiction between direction finding range and direction finding accuracy. In order to relieve the contradiction, multi-baseline phase interferometer is generally used to measure angles. However, this method is mainly aimed at one-dimensional angle measurement, so its system utilization is low. Therefore, a phase interferometer based on multiple antennas is proposed in this paper to measure the angle of pitch and azimuth in two dimensions, and the dual-baseline ambiguity resolution method is used to improve...
INNOVATION IN BOVINE OBSTETRICS: CESAREAN SECTIONS AS A CORNERSTONE IN HEMATITIC FETAL MUMMIFICATION SOLUTIONS
Lakshmi Nair Meera
Fetal mummification is a gestational complication that typically occurs during the fourth, fifth, or sixth month of pregnancy in cows, resulting from the intrauterine death of the fetus. A 4-year-old pluriparous Jersey crossbred cow was presented to the Obstetrics Unit of VCC, VCRI, Orathanadu with a history of mild vaginal discharge and anorexia. The cow had been inseminated eight months prior. Clinical examination revealed a normal physical condition, but vaginal examination showed a two-finger dilation of the cervix's external os and a thickened wall. Rectal examination allowed palpation of a hard, firm fetal mass within the tightly contracted uterus, with...
HARVESTING INSIGHTS: NDVI-BASED ASSESSMENT OF CROP SUITABILITY IN DORNOD PROVINCE, MONGOLIA WITHIN THE KHERLEN BASIN
Oyundelger J. Ganbaatar, Enkhbat T Batbold
The Normalized Difference Vegetation Index (NDVI) is a graphical pixel indicator which used and analysed by remote sensing technology whether or not the target being observed contains live green vegetation. In this paper we estimated crop suitability using Normalized Difference Vegetation Index (NDVI) which depended on Land Surface Temperature (LST), The Normalized Difference Moisture Index (NDMI or water) from MODIS satellite data and Elevation, Slope form ASTER DEM satellite data. NDVI is used for several sector, especially in agriculture for cropland, precision farming and to measure biomass. Agriculture is one of the crucial and traditional sectors of Mongolia that produces...
