Jadual Kuantiti Asas (post khas wat student2 saya)

 

Mengenali kuantiti asas, unit asas dan simbol yang diguna pakai dalam ‘daily life’ mengikut buku-buku fizik… what are those quantities and symbols? Table below describes 5 kuantiti asas yang perlu diketahui… kira macam perkara wajib la…

 (all info are taken from: tripod.com)

 

Jadual 1.1 menunjukkan kuantiti asas, unit asas dan simbol bagi unit asasnya:

 

And in SI units:

 -   1 meter = Jarak yang dilalui oleh cahaya dalam vakum dalam selang masa 1 ÷  299792458 saat

-   1 kilogram = Jisim satu bongkah silinder aloi platinum-iridium yang disimpan di Biro Antarabangsa bagi Berat dan Sukatan di Sevres, Paris.                          

-   1 saat = Masa yang sama dengan 9192631770 kali tempoh sinaran yang  dikeluarkan oleh atom saesium-1.

-   1 kelvin = 1 ÷ 273.16 suhu termodinamik takat tigaan air (takat ais, air dan stim berada dalam keseimbangan pada tekanan tertentu).

-   1 ampere = 1 ampere ialah arus mantap yang mengalir dalam dua konduktor selari yang panjangnya tak terhingga, luas keratan rentas boleh diabaikan dan dipisahkan sejauh 1 meter dalam vakum yang menghasilkan daya sebanyak  2 × 10⁷ newton per meter di antara konduktor-konduktor itu.

ABSTRACT

Mobile networking environments have been developing very rapidly in line with the increase demand of users. The interaction between different protocols to improve handover performance in IPv6 has become a very hot topic . The research objective is to reduce mobile node’s handover processing and packet delay in the establishment of new services. Discussion on different proposal that enhance mobility and architecture for efficient mobile multicast has become an interest for reseachers. This architecture improves the performance in terms of less handover delay and packet loss

OMNeT++… What Is IT????

-a discrete event simulation, mainly of communication networks.
-can be used in other areas, example simulation of complex IT systems, queueing networks or hardware architectures as well.
-extensive GUI support, and the simulation kernel can be embedded easily into other applications.
-comes with different version or suits depending on the platforms.
-guess what??… it is free for noncomercial purpose — academic research.

What is NS-2?

-Network Simulator 2.
-It is an open-source software which can be freely downloaded from its official website.
-There are many available versions with different protocol of interest.
-Basically, the procedures of NS-2 simulation execution involve providing traffic pattern and mobility pattern to a simulation scenario
-The results obtained may be in the form of raw data and that can be interpreted by using appropriate programming language
