Huge antiquity

Today, I went to one of hundreds ancient regions in Persia, near of Neyshabur town, northeastern Iran. Neyshabur is situated 46 miles (74 km) west of Mashhad. The town, which has shifted its position repeatedly in historical times, lies at an elevation of 3,980 feet (1,213 m) in a wide, well-watered, and fertile plain at the southern foot of the Binalud Mountains.

There are some world famous human's tombs in that region such as Attar, Khayyam, and Kamalolmolk.

Omar Khayyam

Persian poet, mathematician, and astronomer, renowned in his own country and time for his scientific achievements but known to English-speaking readers for his roba'iyatThe Rubáiyát of Omar Khayyám.

Shadyakh asleep historical town

In some meter far from Khayyam's tomb an asleep town in about 2 meters under ground explored in recent years… this town has 700 years archaism and its architecture and rooms are very exciting!

Smithy, dungeon, cellar rooms for extracting grape and residential rooms are wonderful in shadyakh!(क्लिक्क फॉर बिग्गेर इमेज)

In this town except of architecture and rooms, very things had been explored such as some wonderful skeleton bodies with different archaism and some dishes and container and some types of pegs. Name of this town is Shadyakh and because this name was repeated in some historical texts causes to explore by scientists. I think if scientists have been research in that region again causes to exploring more monuments…

Three skeleton bodies that was died in an earthquake 700 years before and very wonderful skeleton body with 5300 years old!! Yes, I don’t know about true or false of it but in this region with famous historical background is not an exaggeration!!! You find it in this picture:

She was lived in 5300 years before and was a member from 7000 years of Persia's written history.

She is a 35 Persian woman and found under a residential room…

ARM Microprocessors is it suitable?

some days ago i had an offer about very exciting project about Computer LAN Networks!
but this project is not an usual project for me and i must gather some rare informations
from the web to implementing of it...
during these days i understand that i must use a microcontroller with high speed option more than 50MHz because for having a connection in a 100Base Ethernet network need 50 MHz speed for processing packets and frames to transceive... AVR microcontrollers is not suitable because they work up to 16 MHz and is very low speed for this purpose... having this problem cause me to finding ARM Microprocessors that worked up to 400MHz and is suit for a OS such as linux,WinCE,Symbian,... on some processing devices!!!
Atmel Company have some ARM processors with AT91SAM nick name and i think it is proper to use ...
ARM Micros are some series with different characteristics in ARM7 ,ARM9,ARM10,ARM11 generations.
I thinks AT91SAM7S256 is good for my project this microprocessor is in ARM7TDMI Range.
but i am searching in the web for its limitations and abilities that may cause me...

MSI Circuits

Techniques were developed to put more and more complex circuits on the same chip, evolving into medium scale integration (MSI). Since these circuits are more reliable, cost less, and use less power than the transistors equivalents, they are easier and chiper to use. These circuits have found widespread use in the electronics world.
The evolution of the large scale integration (LSI) circuits opened the door for microprocessors.Developing the LSI capability required new concepts in circuits, manufacturing methods, and testing. New techniques were developed to improve the yield of the manufacturing and testing processes. All this required hundreds of thousands of dollars worth of engineering and development time.

First Start

In the name of God.

first, better work is starting with name of God.

My main purpose for creating this weblog is increasing ability to writing english language
and getting ready for speeking english truly.

i like relation with other people in all off the word to getting more information that
i need to live better...

good luck
