Kamera tersembunyi

Kamera (gadget) 

Kamera ialah alat yang digunakan untuk merakam imej sebagai gambar foto yang pegun atau satu susunan imej bergerak (filem atau video)
yang pastinya semua orang tahu apa itu kamera , mungkin masyarakat yang tinggal di pelusuk pendalaman sahaja yang tidak tahu akan kewujudan kamera.maklumlah zaman Milenium.

kebaikannya memang ada tetapi ada sesentengah individu dan pihak menggunakannya dengan salah.
Contoh terbaik adalah,pihak hotel yang tidak bertanggungjawab memasang kamera tersembunyi di dalam bilik hotel untuk merakam  aktiviti yang dilakukan oleh pelanggan.Tujuannya ,pikir kan sendiri.

untuk langkah penjagaan,boleh la menggunakan (camera detector)
-Alat pengesan kamera tersembunyi
-Boleh kesan di mana camera tersembunyi samaada di tandas dan sebagainya
-Sebagai langkah keselamatan peribadi anda..

Geotechnical Engineering -A historical Perpective

   For Engineering purpose ,soil is defined as uncemented aggregate of mineral grains and decayed organic matter (solid particles) with liquid and gas n the empty spaces between the solid particles.Soil is used as a construction material in various civil engineering projects and it support structural foundations.Thus,civil engineers must study the properties of soil,such as its
  1. origin,
  2. grain size distribution,
  3. ability to drain water
  4. compressibility,
  5. shear strength
  6.  and load bearing capacity.
 Soil Mechanics is the branch of science that deals with the study of the physical properties of soil and the behaviour of soil and the behaviour of soil masses subjected to various types of forces.

 Soil Engineering is the application of the principle of soil mechanics to practical problems.

Geo technical engineering is the sub discipline in Civil Engineering that involves natural materials found close to the surface of the earth.

All of this includes the application  of the principles of soil mechanics to design of foundation,retaining structures and earth structures.
