We report optical photometry and Hi synthesis observations of the southern edge-on S c,d galaxy IC 5249. The observations were carried out primarily to determine if IC 5249 has a red halo surrounding it similar to the halo that has recently been found surrounding the northern edge-on galaxy NGC 5907. The galaxy IC 5249 is almost perfectly edge-on, and it shows no direct sign of warping or flari...

Vegetasi di daerah perkotaan tumbuh diantara gedung dan jalan. Bangunan sekitar pohon berdampak pada identifikasi tanaman menggunakan citra drone. Paper ini menjelaskan tentang perbandingan kemampuan drone band cahaya tampak, near infrared, red-edge untuk tropis perkotaan. Kami menyusun dataset yang berisi paduan saman (Samanea Saman), cemara (Casuarina equisetifolia), pohon-lain. Setiap melalu...
To accurately estimate leaf area index (LAI) in mangrove areas, the selection of appropriate models and predictor variables is critical. However, there is a major challenge in quantifying and mapping LAI using multi-spectral sensors due to the saturation effects of traditional vegetation indices (VIs) for mangrove forests. WorldView-2 (WV2) imagery has proven to be effective to estimate LAI of ...
Previously in class we proved that if we color the edges of K6 using blue or red color, then either there is a blue K3 or a red K3 as a subgraph. Here Kn is the complete graph (every pair of vertices are connected) on n vertices. We can generalize the above concept and ask, are there complete graphs for which any 2-coloring gives rise to either a blue Kk or a red Kl. It has been shown that ther...
Using our non-local time-dependent theory of convection, the linear non-adiabatic oscillations of 10 evolutionary model series with masses of 1–3M⊙ are calculated. The results show that there is a red giant instability strip in the lower temperature side of the Hertzsprung-Russel (HR) diagram which goes along the sequences of the red giant branch (RGB) and the asymptotic giant branch (AGB). For...
ESA's upcoming satellite Sentinel-2 will provide Earth images of high spatial, spectral and temporal resolution and aims to ensure continuity for Landsat and SPOT observations. In comparison to the latter sensors, Sentinel-2 incorporates three new spectral bands in the red-edge region, which are centered at 705, 740 and 783 nm. This study addresses the importance of these new bands for the retr...
Camouflaged Object Detection (COD) aims to detect objects with similar patterns (e.g., texture, intensity, colour, etc) their surroundings, and recently has attracted growing research interest. As camouflaged often present very ambiguous boundaries, how determine object locations as well weak boundaries is challenging also the key this task. Inspired by biological visual perception process when...
