Flash Interactive - Pistons and the Period of a Sine Curve (from www.intmath.com)

Here's another interactive that you can use to explore the concept of period and frequency. The frequency = 1/period. We'll see more on this below.

The piston engine is the most commonly used engine in the world. Its motion can be described using a sine curve.

Things to Do

1. Click "Start" and you will see a sine curve traced out as the piston goes up and down.
2. Now, change the value of b using the slider. If you increase b, the period for each cycle will go down and the frequency will increase. Click "Start" again to see the effect of your change.
3. Observe the number of cycles that you see between t = 0 and t = 2π. For b = 1 you see one cycle, for b = 2, you see 2 cycles, and so on. If b < 1, you do not see any complete cycles.

The units along the horizontal (time) axis are in radians. So 3.14 = π radians and 6.28 = 2π radians.

Introduction

Di bawah ini adalah slides pengantar kuliah Jaringan Nirkabel; meliputi sejarah, sistematika bab, dan ruang lingkup pembahasan. Penting untuk memberikan gambaran awal dan global tentang kuliah ini. Mohon dibaca juga aturan main dan petunjuk di bawah:



Adapun aturan kuliah kita adalah sebagai berikut:

1. Setiap kelompok memiliki tugas untuk menerjemahkan dan menjelaskan slides yang ada dengan bahasa yang lugas dan mudah difahami. Serta disertai dengan praktek, simulasi, atau pembuatan prototype (tidak hanya teori).
2. Setiap mahasiswa wajib terlibat dalam diskusi online melalui blog comments. Saya kadang kala akan memantik diskusi dengan beberapa pertanyaan/pernyataan. Tapi lebih bagus lagi kalau topik dari Anda sendiri. Waktu diskusi adalah seminggu sebelum sebuah topik/bab dipresentasikan. Setelah itu comments akan ditutup. Jangan lupa dengan nama asli (depan atau belakang), jangan nama alias karena tidak sesuai absensi.
3. Setiap mahasiswa wajib terlibat dalam diskusi offline ketika presentasi kelompok di kelas.
4. Have fun and enjoy!
