My trip to Bukit Bintang and Museum Negara

 The MRT tourist map I made

A metal chair at Museum Negara.


  1. When you reach the Bukit Bintang station, don't go through the ticket gate immediately.
  2.  You should first look for the correct exit. 
  3. Head towards the exit, then exit the ticket gate.
  4. Map of Bukit Bintang station and information of places nearby.

Ez-12 Parabolic Reflector (Windsurfer Wifi Extender) Experiment




  1. 固定性变数: 测量WiFi强度的地点;摆放WiFi增幅器的位置;测量WiFi强度的仪器;摆放路由器的地点。
  2. 操纵性变数:WiFi增幅器的大小;WiFi增幅器的数量。
  3. 反应性变数:实验后,WiFi的读数。
  4. 假设:WiFi增幅器的数量越多,实验后,WiFi强度的读数越高;WiFi增幅器越大,实验后,WiFi强度的读数越高。
  5. 目地:为了研究WiFi增幅器的大小和数量,与实验后,WiFi的读数之间的关系。
  6. 观察:在2.4 Ghz的频率,WiFi增幅器的大小和数量在近距离大致上没有改变WiFi的强度在;在远距离WiFi增幅器的大小没有改变WiFi的强度;在远距离,放3个WiFi增幅器时,WiFi的强度比没有WiFi增幅器提高了10 dBm。
  7. 观察2:在5 Ghz的频率,WiFi增幅器的大小和数量在近距离大致上没有改变WiFi的强度在;在远距离WiFi增幅器的大小没有改变WiFi的强度;在远距离,放3个WiFi增幅器时,WiFi的强度比没有WiFi增幅器提高了20 dBm。
  8. 原应(推断):WiFi增幅器把WiFi集中并传出更远,提高远距离的WiFi强度,在进距离却只有很少帮助。
  9. 结论:WiFi增幅器的数量越多,实验后,WiFi强度的读数越高;WiFi增幅器越大,实验后,WiFi强度的读数保持不变。

Ticket to Mars!


     

get your ticket here!
NASA stands for National Aeronautics and Space Administration. NASA was started in 1958. NASA was in charge of U.S.science and technology that got something with airplanes or space. NASA does a lot of different things like making satellites.

Filling in the form won't send you to Mars. However, your name will be sent to Mars in a microchip. A future Martian might be able to find your name in the microchip. Your name will be a part of  Martian history.
