Abstract

Sekarang ini banyak dikembangkan metode penyelesaian masalah secara komputasi. Pada penelitian ini dikonstruksi suatu transformasi wavelet menggunakan operator dalam aljabar max-plus yang disebut sebagai MP-Wavelet. Hasil konstruksi ini secara komputasi membutuhkan waktu yang lebih cepat daripada transformasi wavelet pada umumnya. Pada konstruksi ini dihasilkan satu tipe MP-Wavelet yang disebut dengan MP-Wavelet tipe B. MP-Wavelet tipa ini merupakan pengembangan dari penelitian Fahim yang dipublikasikan pada “Seminar Nasional Pendidikan Sains Tahun 2014” dan “Konferensi Nasional Matemtika 17”. Tipe B ini digunakan untuk pemampatan citra. Untuk melihat hasil rekonstruksi pada proses pemampatan citra “Lena”. Dari simulasi pemampatan ini didapatkan bahwa MP-Wavelet tipe B ini menghasilkan rekonstruksi citra yang lebih baik daripada tipe I yang dikonstruksi oleh Nobuhara (2010); dan tipe I serta tipe A Fahim (2014).

Abstract

Ruang b–metrik cone merupakan perluasan dari ruang b–metrik dan ruang metrik cone. Pada paper ini, diselidiki eksistensi dan sifat ketunggalan titik tetap pemetaan kontraktif pada ruang b–metrik cone yang lengkap. Selanjutnya, dikaji fungsi b-metrik pada ruang b-metrik cone dan dibuktikan beberapa teorema ekivalensi antara kedua ruang tersebut dengan disertai beberapa contoh terkait, khususnya ruang b-metrik cone bernilai

Abstract

Metrics have an important role in mathematics, both in analysis as well as applications. One of the new concepts of metric space is fuzzy -metric space. This metric space is an expansion of the fuzzy metric space by adding  generator. In this paper, we discuss characterization of F-bounded in the fuzzy -metric space. The property of F-bounded is obtained from the compact subset of a given universe set. This characteristic has been discussed by Changqing and Kedian in Hausdorff fuzzy metric spaces. In this paper, the necessary and sufficient conditions are obtained so that the fuzzy  -metric space satisfies the properties of F-bounded.

Abstract

The metric space is one of the objects studied in functional analysis. The metric space has undergone many developments, some eHamples of which are partial metric spaces and rectangular metric spaces. The difference between the metric space and the partial metric space can be seen in the distance of a point from itself. In the metric space, it is always equal to zero, while in the partial metric space it is not equal to zero. On the other hand, the difference between a metric space and a metric rectangular space can be seen in the inequalities used. In the metric space we use triangular inequalities, while in the metric rectangular space we use rectangular inequalities.  Shukla in 2014 presents the development of another metric space called  rectangular partial metric space, which combines the concept of  partial metric space with  rectangular metric space. This research we discusses the problem of the properties of the rectangular partial metric space, including convergence sequences, Cauchy sequences, and completeness of space in the rectangular partial metric space.
