ERNA and Friedman's reverse mathematics
No full textElementary Recursive Nonstandard Analysis, in short ERNA, is a constructive system of nonstandard analysis with a PRA consistency proof, proposed around 1995 by Patrick Suppes and Richard Sommer. Recently, the author showed the consistency of ERNA with several transfer principles and proved results of nonstandard analysis in the resulting theories (see [12] and [13]). Here, we show that Weak Konig's lemma (WKL) and many of its equivalent formulations over RCA(0) from Reverse Mathematics (see [21] and [22]) can be 'pushed down' into the weak theory ERNA. while preserving the equivalences, but at the price of replacing equality with equality 'up to infinitesimals'. It turns out that ERNA plays the role of RCA(0) and that transfer for universal formulas corresponds to WKL

Penentuan Koe¯sien Daya Angkat PesawatTerbang Layang terhadap Gerakan Angin Vertikal
No full textPermasalahan penentuan waktu terbang minimum dari sebuah pesawat terbang layang akibat pengaruh gerakan angin vertikal adalah merupakan permasalahan kontrol optimal non linear atau permasalahan optimasi non linier. Sedangkan penentuan waktu tercepat dengan lintasan bebas, adalah merupakan permasalahan penentuan fungsi pengontrol pesawat terbang layang yang dipengaruhi kecepatan angin sehingga dicapai sasaran yang tepat dengan waktu tercepat. Dalam makalah ini dikaji penentuan fungsi pengontrol yang sesuai untuk mendapatkan waktu minimum dengan keadaan awal dan akhir lintasan pesawat adalah tetap. Masalah ini diselesaikan secara numerik dengan menggunakan metode Runge-Kutta Order Empat. Hasil simulasi dilakukan untuk beberapa kecepatan angin yang berbeda, se- hingga diperoleh fungsi pengontrol yaitu sudut angkat untuk masing-masing kecepatan angin dengan waktu terbang minimum
KAJIAN ANALISIS DALAM METODE ASIMILASI DATA
No full textAsimilasi data adalah suatu metode estimasi yang diperolehdari penggabungan antara model sistem dan data-data pengukuran. Salah satu metode asimilasi data adalah Kalman lter yang merupakan metode estimasi variabel keadaan dari sistem dinamik stokastik. Filter Kalman telah banyak diterapkan pada berbagai bidang ilmu antara lain hidrodinamika, meteorologi, navigasi pesawat dan masalah matematika nansial. Algoritma dasar dari Filter Kalman telah banyak mengalami perkembangan agar dapat diterapkan pada masalah real dan mempunyai waktu komputasi yang cepat. Pada makalah ini akan disajikan beberapa contoh pengembangan algoritma lter Kalman atau asimilasi data secara umumyang memerlukan kajian analisis. Aspek-aspek analisis yang sering diperlukan antara lain norm matriks, konvergensi dan kestabilan
Metode Asimilasi Data sebagai Estimasi Penyelesaian Masalah-masalah Lingkungan
No full textAsimilasi Data merupakan metode estimasi sistem dinamik stokastik yang merupakan penggabungan model dinamik dengan data-data pengukuran. Metode Asimilasi data telah banyak digunakan dalam mengestimasi masalah-masalah meteorologi, hidrodinamika. Di sini akan dibahas tentang apa metode asimilasi data itu, bilamana dipergunakan, apa kelebih- annya dibandingkan dengan metode lainnya serta bagaimana penerapannya pada masalah lingkunga
