Abstract

pada paper ini menjelaskan transformasi Fourier baik yang bernilai real maupun yang bernilai quaternion. Perbedaan mendasarnya terletak pada kernel transformasi, dimana pada transformasi Fourier quaternion dibedakan menjadi tiga jenis, yaitu sisi kiri, sisi kanan dan dua sisi. Adapun sifat-sifat yang dibuktikan seperti pergeseran, modulasi, pengskalaan dan lain-lain (TFQ sisi kanan).

Abstract

Penelitian ini membahas tentang pengukuran kualitas Layanan Program Studi Matematika Fakultas Sains dan Teknologi UIN Alauddin Makassar dengan Metode Sig-Sigma dengan Tahapan Define, Measure, and Analyze . Adapu n Tujuan Penelitian yaitu Mengetahui besar pengukuran layanan kinerja program studi matematika Fakultas Sains dan Teknologi Uin Alauddin Makassar dengan pendekatan six sigma. Hasil Penelitian Menunjukkan bahwa pengukuran kualitas layanan dengan 5 indikator diantaranya, Keandalang, Daya Tanggap, Jamina, Empati dan Bukti Fisik diperoleh bahwa pada kapabilitas proses diperoleh nilai hanya pada indicator andalan pada penggunaan 1-sigma dan 4 indikator lainnya memperoleh indeks . Dari hasil indeks kapabilitas proses dapat disimpulkan bahwa proses layanan yang berjalan saat ini pada program studi matematika masih kurang dan perlu dilakukan perbaikan dan peningkatan  untuk beberapa proses layanan yang sudah sesuai harapan mahasiswa.

Abstract

Let  be a graph and  be an ordered subset of the vertex set og graph  The representation of a vertex  in  with respect to is defined as , where  is the distance between vertex  and  for all $ The set  is called a resolving set of  if the representation of every vertex in  is distinct. A resolving set with the minimum cardinality is called a basis of  and the cardinality of a basis of  is the metric dimension of the graph . A vertex in  is called an isolated vertex if there are no edges incident to . A resolving set  is called a non-isolated resolving set if the subgraph induced by does not contain isolated vertices. A non-isolated resolving set with the minimum cardinality is called an -basis of , and the number of its members is called the non-isolated resolving number of , nonated by . In this paper, we discuss non-isolated resolving numbers of a graph obtained from the corona product of two graphs. The corona product of graph  and graph , denoted by , is a graph obtained by taking one copy of  and as many copies of  as there are vertices in , then connecting every vertex from the -th copy of  to the -th vertex in . The results show that if  is a wheel graph or a fan graph, then the non-isolated resolving number of the corona product  depends on the number of vertices in the graph
