TFRH robot is based on embedded system. The TFRH has mainly two Atmel AT89S52 microcontrollers which communicate with each other via an RF module 434 Mhz. This will be explained in the forthcoming sections. The TFRH is based on 8-bit microcontroller The IC used was Atmel AT89S52 ICS. The hardware cost is reduced by removing various sub ICs used in the design. The design part had successfully removed the 8255 IC and had used multiplexer cd 4051 to support the 7 different motor for the various function

Phaedra Rosengarth 10/20/14 NT1110 Unit 5 Analysis 1: Pentium Flaw The nature of the Pentium flaw was in the floating – point math subsection. In certain conditions‚ low order bits of the result of floating-point division operations would be incorrect. This would lead to an error that will quickly compound in operations to larger errors when future calculations were completed. The flaw was first discovered in June 1994‚ when Intel engineers first noticed that the floating-point unit (FPU) on the

There are 3 questions on this exam. You have 2 hours to complete it. Please do your own work. 1. The number 124 has the property that it is the smallest number whose first three multiples contain the digit 2. Observe that 124*1 = 124‚ 124*2 = 248‚ 124*3 = 372 and that 124‚ 248 and 372 each contain the digit 2. It is possible to generalize this property to be the smallest number whose first n multiples each contain the digit 2. Write a function named smallest(n) that returns the smallest number
