Non-Gaussianity analysis of GW background made by short-duration burst signals

We study an observational method to analyze non-Gaussianity of a gravitational wave (GW) background made by superposition of weak burst signals. The proposed method is based on fourth-order correlations of data from four detectors, and might be useful to discriminate the origin of a GW background. With a formulation newly developed to discuss geometrical aspects of the correlations, it is found that the method provides us with linear combinations of two interesting parameters, I_2 and V_2 defined by the Stokes parameters of individual GW burst signals. We also evaluate sensitivities of specific detector networks to these parameters.Comment: 18 pages, to appear in PR

Fear Management of Flood

This research is intended to identify the management of fear toward flood of eachresidence and compare fear management of flood between 2 residences. Since fear ismental state, which can be explored by questioning the object, questionnaire is used asresearch instrument. Questionnaire was developed to measure fear management, sothat fear management is categorized as latent variable. Therefore, SEM is used toanalyze data. Result show that from the view of flood fear, there is different betweenhabitants in Kampung Melayu and Kelapa Gading. Habitants in Kampung Melayushown the more risk flood experience than them in Kelapa Gading. As well, it can befound also the different between habitants in the two areas based on fear of floodmanagement. It can be also stated that habitants in Kelapa Gading have bettermanaging the risk of flooding in long term than in Kampung Melayu; whereas habitantsin Kampung Melayu manage the risk of flooding in short term. This result can be usefulinformation to government in order to manage the relocation on the time needed

Perasaan dan Sikap terhadap Promosi Berdasarkan Jenis Kelamin

Tujuan dari penelitian ini adalah mengukur perbedaan perasaan dan sikap siswa perempuan dan laki-laki terhadap promosi. Partisipan pada penelitian ini adalah siswa Sekolah Menengah Atas Negeri (SMAN) unggulan di lima (5) wilayah DKI Jakarta. Perasaan dan sikap bersifat subjektifitas pada individu, maka penenelitian ini menggunakan kuesioner sebagai alat pengumpulan data. Meskipun demikian, penelitian ini tergolong sebagai percobaan semu, karena presentasi digunakan sebagai perlakuan untuk memengaruhi perasaan dan sikap partisipan. Berhasil dikumpulkan 392 partisipan. Data selanjutnya diolah menggunakan model persamaan struktural. Hasil penelitian menunjukkan bahwa tidak ditemukan perbedaan antara siswa laki-laki dan perempuan dalam merasakan dan menyikapi promosi. Juga ditemukan bahwa promosi yang diberikan tidak memengaruhi perasaan dan sikap siswa perempuan dan laki-laki terhadap karir bidang TI/komputer

The aim of this research is to evaluate the differences of human resource between senior highhomeschooling students and civil senior high school students in Jakarta with self-regulatedlearning. The participants of this research are 80 students, which is 40 students are fromsenior high homeschooling students and the other 40 students are from civil senior highschool students in detail. This research uses quasi experimental with senior highhomeschooling students as experiment group and civil senior high school students in Jakartaas control group. The result shows significant differentiation in human resource betweensenior high homeschooling students and civil senior high school students in Jakarta. Thisfinding shows that homeschooling would be able to develop competitive human resource withself-regulated learning

Pengaruh Metode Pembelajaran Penugasan Dan Media Pembelajaran Terhadap Prestasi Belajar Siswa

The objective of research was to find out: (1) whether or not there is a significant effect of assignment learning method on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013; (2) whether or not there is a significant effect of learning media on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013; and (3) whether or not there is a significant effect of assignment learning method and learning media simultaneously on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013.This study was a quantitative research with descriptive method. The population of research was all X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013 consisting of 79 students. The sample consisted of 44 students. The sampling technique used was proportional random sampling. Meanwhile technique of collecting data used was questionnaire and documentation technique. Technique of analyzing data used was statistic test with correlational and multiple regression analyses. Considering the result of data analysis, it could be concluded that (1) there was a significant effect of assignment learning method on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013; (2) there was a significant effect of learning media on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013; and (3) there was a significant effect of assignment learning method and learning media simultaneously on main handling course in the X graders of Office Administration Skill Competency in SMK Negeri 3 Surakarta in the school year of 212/2013.The multiple linear regression equation was Ŷ = 50.929 + 0.293 X1 + 0.255 X2. The relative contribution of (X1) to (Y) was 53.72% and that of (X2) to (Y) was 46.28%. Meanwhile the effective contribution of (X1) to (Y) was 23.15% and that of (X2) to (Y) was 19.95%

Prospects for direct detection of circular polarization of gravitational-wave background

We discussed prospects for directly detecting circular polarization signal of gravitational wave background. We found it is generally difficult to probe the monopole mode of the signal due to broad directivity of gravitational wave detectors. But the dipole (l=1) and octupole (l=3) modes of the signal can be measured in a simple manner by combining outputs of two unaligned detectors, and we can dig them deeply under confusion and detector noises. Around f~0.1mHz LISA will provide ideal data streams to detect these anisotropic components whose magnitudes are as small as ~1 percent of the detector noise level in terms of the non-dimensional energy density \Omega_{GW}(f).Comment: 5 pages, 1 figure, PRL in pres

Relativistic Resonant Relations between Massive Black Hole Binary and Extreme Mass Ratio Inspiral

One component of a massive black hole binary (MBHB) might capture a small third body, and then a hierarchical, inclined triple system would be formed. With the post-Newtonian approximation including radiation reaction, we analyzed the evolution of the triple initially with small eccentricities. We found that an essentially new resonant relation could arise in the triple system. Here relativistic effects are crucial. Relativistic resonances, including the new one, stably work even for an outer MBHB of comparable masses, and significantly change the orbit of the inner small body.Comment: 9 pages, 5 figures, to appear in PR

Signature of the Overhauser field on the coherent spin dynamics of donor-bound electron in a single CdTe quantum well

We have studied the coherent spin dynamics in an oblique magnetic field of electrons localized on donors and placed in the middle of a single CdTe quantum well, by using a time-resolved optical technique: the photo-induced Faraday rotation. We showed that this dynamics is affected by a weak Overhauser field created via the hyperfine interaction of optically spin-polarized donor-bound electrons with the surrounding nuclear isotopes carrying non-zero spins. We have measured this nuclear field, which is on the order of a few mT and can reach a maximum experimental value of 9.4 mT. This value represents 13 % of the maximal nuclear polarization, and corresponds also to 13 % of maximal electronic polarization.Comment: 15 pages, 4 figure

Recognition of Recording and Reporting Accounting at Tour and Travel

This final assignment is done in tour and travel. The company didn't record any transaction conducted, the company only used receipt as transaction evidence. So that the company experienced difficulties in determining the exact profits obtained. Based these problems, the researcher gives a guide in recording transactions and making financial statements so company can keep records in every transactions to improve accounting process especially in making financial statements
