    We report on the spectral evolution of 6 classical novae, V1186 Sco, V2540 Oph, V4745 Sgr, V5113 Sgr, V458 Vul, and V378 Ser, based on the low-resolution spectra obtained at the Fujii-Bisei Observatory and the Bisei Astronomical Observatory, Japan. In the light curves, these 6 novae show several rebrightenings during the early phase lasting ~10 days after the first maximum in fast novae, and ~100 days in slow novae. The early spectra of all of these novae had emission lines with a P-Cygni profile at the maximum brightness. The absorption component of the P-Cygni profiles then disappeared after the maximum, and reappeared when the novae brightened to the next maximum. We suggest that the re-appearance of the absorption component at the rebrightening is attributable to re-expansion of the photosphere after it once shifts sufficiently inside. From the light curves, we found that the time intervals of the rebrightenings of these 6 novae show a similar systematic trend, which is applicable to all types of novae: fast and slow, and Fe II type and hybrid type. Moreover, we note the difference between the spectra at the rebrightenings during the early phase and at the rebrightening in V2362 Cyg, and at the oscillation during the transition phase in V1494 Aql, which means difference of the physical mechanism of the rebrightening during the early phase and the later oscillations.Comment: 11 pages, 15 figures, accepted for publication in PAS

    Fast Freenet: Improving Freenet Performance by Preferential Partition Routing and File Mesh Propagation

    Get PDF
    The Freenet Peer-to-Peer network is doing a good job in providing anonymity to the users. But the performance of the network in terms of download speed and request hit ratio is not that good. We propose two modifications to Freenet in order to improve the download speed and request hit ratio for all participants. To improve download speed we propose Preferential Partition Routing, where nodes are grouped according to bandwidth and slow nodes are discriminated when routing. For improvements in request hit ratio we propose File Mesh propagation where each node sends fuzzy information about what documents it posesses to its neigbors. To verify our proposals we simulate the Freenet network and the bandwidth restrictions present between nodes as well as using observed distributions for user actions to show how it affects the network. Our results show an improvement of the request hit ratio by over 30 times and an increase of the average download speed with six times, compared to regular Freenet routing

    Spectral Evolution of the Unusual Slow Nova V5558 Sgr

    We report on the spectral evolution of the enigmatic, very slow nova V5558 Sgr, based on the low-resolution spectra obtained at the Fujii-Bisei Observatory and the Bisei Astronomical Observatory, Japan during a period of 2007 April 6 to 2008 May 3. V5558 Sgr shows a pre-maximum halt and then several flare-like rebrightenings, which is similar to another very slow nova V723 Cas. In our observations, the spectral type of V5558 Sgr evolved from the He/N type toward the Fe II type during the pre-maximum halt, and then toward the He/N type again. This course of spectral transition was observed for the first time in the long history of the nova research. In the rebrightening stage after the initial brightness maximum, we could identify many emission lines accompanied by a stronger absorption component of the P-Cygni profile at the brightness maxima. We found that the velocity of the P-Cygni absorption component measured from the emission peak decreased at the brightness maxima. Furthermore, we compared the spectra of V5558 Sgr with V723 Cas, and other novae which exhibited several rebrightenings during the early phase.Comment: 8 pages, 7figures, accepted for publication in PAS

    Ethnomathematics is a study that combines mathematics and culture. Culture is a legacy passed down from ancestors that becomes a characteristic or characteristic of a particular region, one of the regions that has characteristics that are famous for its culture is the city of Palembang. Palembang city has various cultures that are in great demand by outsiders such as the Limas traditional house and jumputan cloth. Discussing about culture, this is certainly inseparable from learning concepts found in everyday life, one of which is the concept of learning mathematics. Where in this case the researcher takes the concept of mathematics on the phytagorean theorem associated with Limas houses and jumputan cloth. The type of research that researchers use is ethnographic qualitative research. Data sources are primary data and secondary data. Data collection techniques through interviews, observations and documentation. The data obtained was then analysed by data reduction, data presentation, and conclusions and verification. The result of this research is that Palembang culture, namely the Limas house roof, has the application of the phytagoras theorem concept. In the motifs of jumputan fabric patterns and the plan of the Limas house looking sideways contains the concept of proving the truth of the phytagoras theorem

    Get PDF
    Istilah Islam politik merupakan sebuah konsep yang digunakan untuk menjelaskan gejala sosial politik dikalangan aktivis atau sekelompok individu yang mendasarkan gerakan mereka dengan ideologi. Seiring dengan itu, dalam sorotan media massa, wacana Islam politik iu sudah ditentukan oleh hubungan antara; media, wacana Islam politik, serta audiensnya yang dipengaruhi oleh relasi-relasi dibaliknya seperti; kebijakan redaksional media. Tulisan ini mencoba untuk menjawab relasi apa yang melatar belakangi wacana Islam politik dihadirkan di harian Kompas dan harian Republika tentang penyerangan warga Ahmadiyah di Cekeusik, Banten pada 06-02-2001, Penyerangan Gereja di Temanggung, Jawa Tengah 07-02-2011, penyerangan warga Syiah di Sampang, Jawa Timur 28-08-2012, berita partai-partai Islam setelah verifikasi komisi pemilihan umum (KPU) Januari 2013 08-01-2013. Berdasarkan analisis isi yang berparadigma analisis wacana kritis, kedua media nasional ini (harian Kompas dan harian Republika) samasama mampengaruhi pembaca. Bedanya, harian Kompas membingkai wacana ini kedalam dinamika ke-Indonesia-an dalam kerangka kebinekaan dan kesatuan bangsa sedangkan harian Republika membungkus wacana Islam politik kedalam dinamika keislaman. Walaupun demikian kedua media ini sama-sama menekankan arti penting peran pemerintah dalam penanganan kasus Islam politik di Indonesia. Tulisan ini juga bisa dijadikan sebagai bahan kritis dalam pembacaan atas wacana Islam politik di media massa, khususnya di Indonesia
