Finite-level systems, Hermitian operators, isometries, and a novel parameterization of Stiefel and Grassmann manifolds

In this paper we obtain a description of the Hermitian operators acting on the Hilbert space \C^n, description which gives a complete solution to the over parameterization problem. More precisely we provide an explicit parameterization of arbitrary $n$-dimensional operators, operators that may be considered either as Hamiltonians, or density matrices for finite-level quantum systems. It is shown that the spectral multiplicities are encoded in a flag unitary matrix obtained as an ordered product of special unitary matrices, each one generated by a complex $n-k$-dimensional unit vector, $k=0,1,...,n-2$. As a byproduct, an alternative and simple parameterization of Stiefel and Grassmann manifolds is obtained.Comment: 21 page

Prediksi Alokasi Jumlah Produksi Minyak Sawit dengan Metode Regresi Linier Berganda pada PT. Palm Lampung Persada

PT. Palm Lampung Persada Way Kanan is a company engaged in oil palm plantations that produce crude palm oil. This company often experiences problems in the allocation of palm oil production.This research was conducted using multiple linear regression method to predict the allocation of the amount of palm oil production based on learning data using Microsft Excel 2010 and RapidMiner applications. In this study there are dependent variables (free) and independent variables (bound), namely: dependent variable (raw material, amount of labor, rainfall and land area) while the independent variable (palm oil).Calculations using multiple linear regression methods in determining the allocation of the amount of palm oil production can be used to assist companies in making a decision with predictive value close to the original data processed as learning data with a result of 170.811 and original data of 170 and an error value of 0.002

Makna simbolik ritual tiwah suku dayak ngaju sebagai sumber belajar sejarah lokal di Kalimantan Tengah

Penelitian dilakukan dalam upaya mengkaji makna simbolik ritual tiwah suku dayak ngaju yang berpotensi sebagai sumber belajar sejarah lokal di Kalimantan Selatan. Penelitian dengan metode deskriptif kualitatif melalui observasi, wawancara dan studi dokumentasi. Observasi bersifat non partisipasi dalam berbagai kegiatan masyarakat dengan wawancara terstruktur melalui daftar pertanyaan yang telah dirancang sesuai gambaran awal yang di dapat ataupun bebas. Wawancara dilakukan kepada tokoh dayak ngaju, perangkat desa serta guru SMAN Katingan. Analisis data berpedoman pada langkah reduksi data, penyajian data dan  penarikan simpulan. Hasil penelitian menunjukkan makna simbolik yang terdapat dalam tradisi ritual tiwah yaitu ritual tersebut merupakan bentuk tanggung jawab sosial baik berupa tangung jawab masyarakat adat, baik terhadap nenek moyang maupun menjunjung tinggi harkat dan martabat masyarakat atau keyakinan untuk membuang sial bagi keluarga yang ditinggalkan. Kemudian terdapat karakter gotong royong sebagai simbol kehidupan bermasyarakat mengingat ritualnya memerlukan waktu dan biaya besar. Guna menghemat pengeluaran, kini masyarakat Dayak mengadakan upacara tiwah bersama-sama. Lau adanya sikap ungkapan rasa syukur kepada tuhan YME atas nikmat dan permohonan supaya terhindar dari kemalangan, kemiskinan dan keterbelakangan. Makna simbolik itu berpotensi sebagai sumber penyusunan sejarah lokal yang masih kurang bagi sumber belajar siswa di SMA Katingan

Penggunaan Penyelesaian Persamaan Aljabar Riccati Waktu Diskrit pada Kendali Optimal Linier Kuadratik

Permasalahan kendali optimal linier kuadratik adalah mendapatkan aturan kendali optimal () dengan mendapatkan penyelesaian Persamaan Aljabar Riccati Waktu Diskrit (PRAWD) () yang definit positif dan matriks gain umpan Balik (). Untuk proses kendali berhingga, matriks-matriks () dan () adalah varian waktu. Akan tetapi, jika proses tersebut tidak berhingga maka matriks tersebut menjadi matriks konstan dan . Untuk mendapatkan penyelesaian kendali optimal steady state, diperlukan suatu penyelesaian PRAWD steady state. Penyelesaian PRAWD steady state didapat dengan membalik waktu dari PRAWD non steady state. Pendiskritan juga diperlukan untuk menyelesaikan kendali optimal waktu diskrit apabila diberikan sistem waktu kontinu dengan indeks performansi kontinu, contoh kasus adalah sistem servo dengan plant pendulum terbalik. Analisis pada PRAWD menunjukkan sifat invariant dari PRAWD jika matriks pemberat indeks performansi diganti. Perlu diketahui juga bahwa PRAWD memiliki penyelesaian minimum yang unik

The Influence of Marital Adjustment and Family Function Toward Family Strength in Early Marriage
