Physical optics analysis of a four-reflector antenna, part 1

Concern has been raised for the 64-m to 70-m antenna upgrade project that the 70-m system may experience greater S-band beam-pointing perturbations than the 64-m system. The S-band perturbations are due to minor (higher order) mode generation, causing subtle cross-polarization fields affecting beam pointing direction, as described herein. For the antennas in their present configuration (64 m), a slight S-band gain degradation of about 0.05 dB can be attributed to these effects. Therefore, a full physical optics analysis was performed for the present-day 64-m system, as described herein. The results were compared with past analyses and experimental observations in order to verify the algebra and computer code with the intent of deriving a valid analysis method for accurately analyzing the 70-m shaped dual reflector Cassegrainian antenna. The results of the new analysis appear to be in excellent agreement with previous analyses and experimental data

PENGARUH PENGUASAAN KONSEP SUKU BANYAK TERHADAP KEMAMPUAN MENYELESAIKAN MATRIKS SISTEM PERSAMAAN LINEAR MENGGUNAKAN KAIDAH CRAMER

Gina Patriasih. 14111520077. Pengaruh Penguasaan Konsep Suku Banyak Terhadap Kemampuan Menyelesaikan Matriks Sistem Persamaan Linear dengan Menggunakan Kaidah Cramer. Kemampuan menyelesaikan matriks sistem persamaan linear dengan menggunakan kaidah cramer siswa dianggap sudah baik. Hal ini ditandai oleh banyaknya siswa yang sudah mencapai nilai rata-rata cukup memuaskan. Konsep suku banyak merupakan konsep dasar yang harus dipahami untuk menjelaskan materi selanjutnya mengenai matriks sistem persamaan linear dengan menggunakan kaidah cramer. Karena antara materi satu dengan lainnya saling berkesinambungan. Sehingga penguasaan konsep suku banyak dapat meningkatkan kemampuan menyelesaikan matriks sistem persamaan linear dengan menggunakan kaidah cramer. Penelitian ini bertujuan untuk 1) mengetahui penguasaan siswa tentang konsep suku banyak, 2) mengetahui kemampuan siswa di kelas Xdalam mempelajari matriks sistem persamaan linear, 3) Untuk mengetahui pengaruh penguasaan konsep suku banyak siswa terhadap kemampuan menyelesaikan matriks sistem persamaan linear menggunakan kaidah cramer. Penelitian ini dilakukan di SMK Islamic Centre Cirebon, jumlah populasi seluruh siswa kelas X sebanyak 918 siswa. Pengambilan sampling dilakukan dengan teknik cluster random sampling, terpilih kelas X Administrasi Perkantoran 3 sebanyak 43 siswa sebagai sampel penelitian. Berdasarkan pengolahan data, hasil penelitian menunjukkan bahwa nilai rata-rata tes penguasaan konsep suku banyak sebesar 45,11 termasuk kategori cukup baik dan rata-rata tes kemampuan menyelesaikan matriks sistem persamaan linear dengan menggunakan kaidah cramer sebesar 71,39 termasuk kategori sangat baik. Persamaan regresi yang dihasilkan untuk memprediksi kemampuan menyelesaikan matriks sistem persamaan linear menggunakan kaidah cramer berdasarkan penguasaan konsep suku banyak adala

From the page to the screen : representations of zainichi identity

This report looks at how zainichi identity has been constructed and negotiated by prominent zainichi figures in Japan over the past three decades. Zainichi are ethnically Korean and are Korean citizens, but reside in Japan. They straddle both cultures, but belong to neither. My case studies include three prominent zainichi figures: Yi Yangji (1955-1992), a literary author whose semi-fictional works demonstrate the difficulties zainichi experience when trying to adapt to Korean culture; Yū Miri (b. 1968), a politically-engaged author and essayist whose works show the difficulties faced by zainichi who try to maintain a hybrid identity while living in Japan; and Akiyama Yoshihiro (b. 1975), a Mixed Martial Artist and popular culture icon, who successfully straddles the two cultures, capitalizing on his fluid, hybrid identity in order to achieve transnational stardom. For each of these figures, on a personal level, such representations offer a means for them to renegotiate their ties to South Korea and their place in Japan. On a more political and universal level, these artists and their lives are calls for acceptance, both self-acceptance by zainichi as well as by citizens of both nations to embrace the in-betweenness.Asian Studie
