Hot methane line lists for exoplanet and brown dwarf atmospheres
We present comprehensive experimental line lists of methane (CH4) at high
temperatures obtained by recording Fourier transform infrared emission spectra.
Calibrated line lists are presented for the temperatures 300 - 1400 degC at
twelve 100 degC intervals spanning the 960 - 5000 cm-1 (2.0 - 10.4 microns)
region of the infrared. This range encompasses the dyad, pentad and octad
regions, i.e., all fundamental vibrational modes along with a number of
combination, overtone and hot bands. Using our CH4 spectra, we have estimated
empirical lower state energies (Elow in cm-1) and our values have been
incorporated into the line lists along with line positions (cm-1) and
calibrated line intensities (S' in cm molecule-1). We expect our hot CH4 line
lists to find direct application in the modeling of planetary atmospheres and
brown dwarfs.Comment: Supplementary material is provided via the Astrophysical Journal

Islamic Bathroom: A Recommendation of Bathroom Layout Design with Islamic Values
A bathroom is a room that cannot be separated from humans’ daily lives and there are activities performed inside of it. Today’s bathroom usually is designed in the universal style, even though there is no human with the same background nor the same religion. Every religion has its own rules and should be applied by its followers in every aspect of their lives, especially in Islam. There are two guidelines which have the explanation of the bathroom etiquette, Al Quran and Hadits. For the Muslim users, the synchronization between bathroom etiquette and the design of the bathroom is an effort of the observance to Allah SWT. Therefore, this writing is an attempt to give a reminder and also a recommendation of bathroom design layouts based on the rules of Islamic bathroom etiquette. The methodology of this research is to describe all of the bathroom etiquettes in Al-Quran and Hadits and make the concept of the bathroom design layouts based on what is permitted and forbidden
Analisa Perbandingan Logic Fuzzy Metode Tsukamoto, Sugeno, Dan Mamdani (Studi Kasus : Prediksi Jumlah Pendaftar Mahasiswa Baru Fakultas Sains Dan Teknologi Universitas Islam Negeri Sunan Gunung Djati Bandung)
Universitas Islam Negeri (UIN) Sunan Gunung Djati Bandung salah satu institusi perguruan tinggi yang memiliki kualitas yang bagus dan memiliki potensi yang dapat menyerap mahasiswa baru berdasarkan berlimpahnya data awal yang diperoleh dari tahun ajaran 2013/2014 sampai dengan 2016/2017, dengan tahapan seleksi penerimaan yang banyak bahkan mahasiswa baru yang terserap beberapa tahun terakhir mengalami peningkatan dan penurunan.Dalam penelitian dilakukan analisa perbandingan algoritma fuzzy logic metode Tsukamoto, Sugeno dan Mamdani untuk memprediksi jumlah pendaftar untuk tahun kedepan dilihat dari jumlah mahasiswa yang lulus dan registrasi dari tahun sebelumnya dan dalam membandingkan perhitungannya menggunakan nilai rata-rata dari hasil yang diperoleh pada ketiga metode fuzzy tersebut dengan aplikasi berbasis web.Hasil dari penelitian yang telah dihitung bahwa metode fuzzy Mamdani mempunyai tingkat error yang lebih kecil sebesar 19,76 % dibandingkan dengan metode Tsukamoto sebesar 39,03 % dan Sugeno sebesar 86,41 % pada prediksi jumlah pendaftar mahasiswa baru

Similarity hash based scoring of portable executable files for efficient malware detection in IoT
YesThe current rise in malicious attacks shows that existing security systems are bypassed by malicious files. Similarity hashing has been adopted for sample triaging in malware analysis and detection. File similarity is used to cluster malware into families such that their common signature can be designed. This paper explores four hash types currently used in malware analysis for portable executable (PE) files. Although each hashing technique produces interesting results, when applied independently, they have high false detection rates. This paper investigates into a central issue of how different hashing techniques can be combined to provide a quantitative malware score and to achieve better detection rates. We design and develop a novel approach for malware scoring based on the hashes results. The proposed approach is evaluated through a number of experiments. Evaluation clearly demonstrates a significant improvement (> 90%) in true detection rates of malware
Glycaemic Index Of Uwi, Gadung, And Talas Which Were Given On Rat
The aim of the study was the determination of glycaemic index (GI) of local tubers such as Uwi (Dioscorea alata), Gadung (Dioscorea hispida), dan Talas (Colocasia esculenta). Tubers were prepared as raw flour which were administered orally to the rats. Blood were taken at 0; 0,5; 1 and 2 hour after tubers administration. The dose was 2,5 kg/kg body weight (BW) whereas glucose was administered as a standart treatment. Area Under Curve (AUC) was calculated after plotting the graph of time versus glucose levels. Glucose levels were determined using GOD-PAP kit. GI values were calculated as a ratio of AUC (0-2hr) of tubers to glucose. Porang was moderate while the other tubers were low GI
C-Band All-Sky Survey: A First Look at the Galaxy
We present an analysis of the diffuse emission at 5 GHz in the first quadrant
of the Galactic plane using two months of preliminary intensity data taken with
the C-Band All Sky Survey (C-BASS) northern instrument at the Owens Valley
Radio Observatory, California. Combining C-BASS maps with ancillary data to
make temperature-temperature plots we find synchrotron spectral indices of
between 0.408 GHz and 5 GHz and between 1.420 GHz and 5 GHz for ,
. Through the subtraction of a radio recombination
line (RRL) free-free template we determine the synchrotron spectral index in
the Galactic plane () to be between
0.408 GHz and 5 GHz, with a contribution of per cent from free-free
emission at 5\,GHz. These results are consistent with previous low frequency
measurements in the Galactic plane. By including C-BASS data in spectral fits
we demonstrate the presence of anomalous microwave emission (AME) associated
with the HII complexes W43, W44 and W47 near 30 GHz, at 4.4 sigma, 3.1 sigma
and 2.5 sigma respectively. The CORNISH VLA 5 GHz source catalogue rules out
the possibility that the excess emission detected around 30\;GHz may be due to
ultra-compact HII regions. Diffuse AME was also identified at a 4 sigma level
within , between 5
GHz and 22.8 GHz.Comment: 16 pages, 9 figures, submitted to MNRAS, referee's corrections made,

Effect of Screw Diameter in Femoral Fracture Fixation Modeled by Finite Element Method
Research in the field of biomechanics related to orthopedic implants is rapidly growing in the world, especially for fixation of fractured bone. Fixation is a surgery to locate and attach a plate pressed by screws at the fractured bone. Most of the fracture bones sited in femur. This research focuses on modeling and simulation of plate and screw made of SS316L material for the fixation of the fractured femur using finite element method (FEM). SS316L is a material with good biocompatibility, cheap, and ductile enough. Modeling and simulation done using ANSYS 15.0 software. Simulation results are stress, strain, and total deformation. It is obtained that optimum diameter of screw is 4.5 mm with respect to minimum value of von Mises stress and deformation
Developing Information System on Lunar Crescent Observations
We present a progress report on the development of information system of lunar crescent astronomical observations which will be largely accessible for public domain. This consists of calculations of the Moon's ephemeris as well as systematic real-time lunar crescent observations. A well suited small telescope, equipped with a simple digital detector, is connected to a server to provide information on lunar crescent observations. The system has been used and worked well. The only constraint is poor weather condition. Network of small telescopes, installed at various locations in Indonesia, are currently planned to provide plethora of data. In the long term, this will be used to help to determine the astronomical visibility criteria of lunar crescent for Islamic calendar
