Aplikasi belajar membaca iqro' berbasis mobile

Abstrak Kemajuan Ilmu Pengetahuan dan Teknologi (IPTEK) hendaklah diikuti dengan Iman dan Takwa (IMTAK), sangat disayangkan, jika masih banyak masyarakat yang belum bisa membaca huruf hijaiyah yang merupakan dasar dari Al-Qur’an. Masyarakat sekarang telah disibukkan dengan berbagai aktipitas sehingga mereka sulit untuk belajar dengan Ustad atau Ustadza mengenai huruf hijaiyah. Untuk mengatasi m...

Lag-Lead Compensator for Shape Memory Alloy in Gripping Manipulation

Abstrak Shape Memory Alloy (SMA) adalah salah satu jenis aktuator yang sedang banyak dipelajari pada aplikasi skala mikro dan nano. Namun di sisi lain, pengembangan pengendalian dalam skala ini masih perlu pengembangan dan penelitian lebih lanjut. Artikel ini mempresentasikan hasil evaluasi tanggapan pergerakan kendali kalang tertutup dari TiNi SMA dalam bentuk spring yang dikendalikan kompensa...

Inverse Document Frequency (IDF): A Measure of Deviations from Poisson

Low frequency words tend to be rich in content, and vice versa. But not all equally frequent words are equally mean!ngful. We will use inverse document frequency (IDF), a quantity borrowed from Information Retrieval, to distinguish words like somewhat and boycott. Both somewhat and boycott appeared approximately 1000 times in a corpus of 1989 Associated Press articles, but boycott is a better k...

Understanding inverse document frequency: on theoretical arguments for IDF

The term weighting function known as IDF was proposed in 1972, and has since been extremely widely used, usually as part of a TF*IDF function. It is often described as a heuristic, and many papers have been written (some based on Shannon’s Information Theory) seeking to establish some theoretical basis for it. Some of these attempts are reviewed, and it is shown that the Information Theory appr...
