Individual components have also been supported by the National Aeronautics and Space Administration (NASA) through the Chandra X-ray Center, which is operated by the Smithsonian Astrophysical Observatory for and on behalf of the NASA contract NAS8-03060, and by the Space Telescope Science Institute, operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS5-26555. This research has made use of the NASA/IPAC Extragalactic Database which is operated by the Jet Propulsion Laboratory, California Institute of Technology, under contract with the NASA.

Aggressive source detection methods will result in detection of many false positive source candidates. Candidate detections will then

The library wraps a subset of the lower-level wcslib functions to provide an easy interface to both users and developers. The Transform library is designed to be used within C++ programs

We describe the new face of CIAO, the internal restructuring, the factors that led to the changes, and our vision for further development.

UAD memiliki Lembaga Penelitian dan Pengabdian Masyarakat (LPPM) yang menjadi sarana untuk mempublikasikan penelitian dosen. Dosen diwajibkan melakukan kegiatan ilmiah yaitu penelitian dalam memecahkan masalah dengan cara sistematis yang telah ditetapkan untuk mencapai tujuan yang telah dirumuskan. LPPM UAD mengelola judul penelitian dosen dengan cara menyimpan dan mempublikasikan tetapi belum mengelompokkannya. Berdasarkan permasalahan tersebut, maka penelitian ini bermaksud membuat program untuk mengelompokkan judul penelitian dosen berdasarkan kategori penelitiannya. Metode yang digunakan dalam penelitian ini adalah K-Means sedangkan metode pendekatan yang digunakan adalah Cosine Similarity. Penelitian ini meliputi tahapan dari text mining yaitu tokenizing, filtering, stemming, algortima k-means, menghitung akurasi menggunakan pengujian silhouette coe...
