    Neutrino Mass Ordering at DUNE: an Extra ν\nu-Bonus

    Full text link
    We study the possibility of extracting the neutrino mass ordering at the future Deep Underground Neutrino Experiment using atmospheric neutrinos, which will be available before the muon neutrino beam starts being perational. The large statistics of the atmospheric muon neutrino and antineutrino samples at the far detector, together with the baselines of thousands of kilometers that these atmospheric (anti)neutrinos travel, provide the ideal ingredients to extract the neutrino mass ordering via matter effects in the neutrino propagation through the Earth. Crucially, muon capture by Argon provides excellent charge-tagging, allowing to disentangle the neutrino and antineutrino signature. This is a critical extra benefit of having a Liquid Argon Time Projection Chamber as far detector, that could render a 4σ4\sigma extraction of the mass ordering after ten years of exposure.Comment: 8 pages, 2 figures.

    Image Compression using Discrete Cosine Transform & Discrete Wavelet Transform

    Image Compression addresses the problem of reducing the amount of data required to represent the digital image. Compression is achieved by the removal of one or more of three basic data redundancies: (1) Coding redundancy, which is present when less than optimal (i.e. the smallest length) code words are used; (2) Interpixel redundancy, which results from correlations between the pixels of an image & (3) psycho visual redundancy which is due to data that is ignored by the human visual system (i.e. visually nonessential information). Huffman codes contain the smallest possible number of code symbols (e.g., bits) per source symbol (e.g., grey level value) subject to the constraint that the source symbols are coded one at a time. So, Huffman coding when combined with technique of reducing the image redundancies using Discrete Cosine Transform (DCT) helps in compressing the image data to a very good extent. The Discrete Cosine Transform (DCT) is an example of transform coding. The current JPEG standard uses the DCT as its basis. The DC relocates the highest energies to the upper left corner of the image. The lesser energy or information is relocated into other areas. The DCT is fast. It can be quickly calculated and is best for images with smooth edges like photos with human subjects. The DCT coefficients are all real numbers unlike the Fourier Transform. The Inverse Discrete Cosine Transform (IDCT) can be used to retrieve the image from its transform representation. The Discrete wavelet transform (DWT) has gained widespread acceptance in signal processing and image compression. Because of their inherent multi-resolution nature, wavelet-coding schemes are especially suitable for applications where scalability and tolerable degradation are important. Recently the JPEG committee has released its new image coding standard, JPEG-2000, which has been based upon DWT

    Peda is a fermentation products by additing of salt in certain concentrations. In thefermentation is occurred breaking the complex compound of fish\u27s fat and protein intoseveral simpler compounds by enzymes of fermentor agents (the microbes). This researchwas purposed to know exactly salt concentration in the process of making peda withaddition of lactic acid bacteria from terasi. The type of this research is experiment.Population of this research is all Mackerels which are sold in Bertais market, and 36 ofthem are taken as sample, by purposive sampling. The treatment of this research consistsof 3 concentration of salt, that is 15%, 20% and 25%. Data was taken by using hedonictest by 5 expert panelists. Data was analyzed by using Kruskal-Wallis test. Result showedthat there were no treatment differences of salt and lactic acid bacteria towards hedonictests (P > 0,05). Yet, the most acceptable of peda, is fermented within 25% saltconcentration

    Biji karet merupakan salah satu bahan pakan hasil samping berkualitas dari perkebunan karet yang dapat dijadikan pakan ternak unggas maupun ruminansia. Salah satu kelemahan dari bahan pakan tersebut adalah tingginya kandungan asam sianida (HCN) yang dapat menyebabkan keracunan bila dikonsumsi oleh ternak. Salah satu cara untuk mengeliminasi bahkan menghilangkan kandungan antinutrisi tersebut yaitu dengan proses pengukusan. Penelitian ini bertujuan untuk mengetahui lama waktu pengukusan terhadap penurunan asam sianida maupun Perubahan zat makanan lainnya seperti bahan kering dan bahan organik. Penelitian ini menggunakan Rancangan Acak Lengkap dengan 4 perlakuan dan 4 ulangan. Data yang diperoleh dilakukan Analisis Ragam, sedangkan uji jarak berganda Duncan digunakan sebagai uji lanjut. Perlakuan yang terapkan adalah; P0 (tepung biji karet tanpa pengukusan sebagai kontrol), P1 (pengukusan tepung biji karet selama 10 menit), P2 (pengukusan tepung biji karet selama 20 menit) dan P3 (pengukusan tepung biji karet selama 30 menit). Hasil analisis ragam menunjukkan bahwa lama waktu pengukusan berpengaruh nyata (P<0,05) terhadap HCN tepung biji karet. Hasil penelitian menunjukkan bahwa semakin lama waktu pengukusan semakin signifikan menurunkan kandungan HCN, bahan kering maupun bahan organik tepung biji karet. Dapat disimpulkan bahwa pengukusan tepung biji karet selama 30 menit mampu menurunkan asam sianida 13 kali lebih rendah (9.542 - 0.712%) dibandingkan kontro

    The purpose of this action research is to find out: (1) the improvement of student learning achievement after the implementation of discovery learning and (2) the influence of student learning motivation after the implementation of discovery learning method. This study uses action research as many as three rounds. Each round consists of four stages: design, activity and observation, reflection and refinement. The subject of this study was the sixth grade students of the Gas Semester Blimbing II Elementary School, Paciran Subdistrict, Lamongan Regency, 2015/2016 Academic Year. Data obtained in the form of formative test results, observation sheets of teaching and learning activities. From the results of the data analysis concluded that student achievement has increased from cycle I to cycle III, namely, cycle I (58.33%), cycle II (75%), cycle III (91.33%)

    Mutu memiliki pengertian yang bervariasi. Oleh karena itu,diperlukan sebuah pemahaman yang jelas terhadap variasi maknamutu tersebut. Sebuah pemahaman tentang variasi arti mutu sangatdiperlukan sebagai langkah awal dalam memahami tentang TotalQuality Management (TQM). Total Quality Management (TQM)merupakan perluasan dan pengembangan dari jaminan mutu dantentang usaha menciptakan kultur mutu, yang mendorong semuaanggota stafnya untuk memuaskan para pelanggan. TQM adalahsebuah pendekatan praktis, namun strategis dalam menjalankanroda organisasi yang memfokuskan diri pada kebutuhan pelanggandan kliennya. Bukan merupakan sekumpulan slogan, namunmerupakan suatu pendekatan sistematis dan hati-hati untukmencapai tingkatan kualitas yang tepat dengan cara yang konsistendalam memenuhi kebutuhan dan keinginan pelanggan. Sebagaisebuah pendekatan, TQM mencari sebuah peningkatan danperubahan permanen dalam tujuan sebuah organisasi/lembaga, daritujuan kelayakan jangka pendek menuju tujuan perbaikan mutujangka panjang. Total Quality Management (TQM) adalah suatumakna dan standar mutu dalam pendidikan. maka perlu diingatbahwa dalam manajemen mutu terpadu dalam pendidikan harusmenempatkan pelanggan dan produk sebagai perhatian utama. Olehkarena itu perlunya pengembangan kurikulum secara terus menerusberdasarkan kebutuhan masyarakat yang selalu berkembang.Dimana pelanggan utama pendidikan adalah peserta didik yangmenerima pelayanan pendidikan dan latihan, sedangkan produknyaadalah peluang pembelajaran yang harus tercapai keperluan yangelemennya adalah kurikulum dan sumber daya pembelajaran.Kata Kunci: Mutu, pendidikan, dan Total Quality Managemen
