Afriend of yours is quite excited about having developed a new class of codes: pair codes. pair codes are a generalization of the 2-out-of-5 representation discussed in notes set 4.2 (lumetta's notes). in a pair code, each code word has exactly two 1 bits. however, one can define a pair code on any number of bits n. for example, if n=100, one has 100 bits in the code words, and exactly two 1 bits. your friend points out that as n grows, the fraction of valid code words drops dramatically. for n=100, for example, there are only 4950 valid code words (100 times 99 divided by 2), but there are 2100 bit patterns. your friend argues that error correction capabilities for pair codes must be quite powerful, since the codes are so sparsewhat is the hamming distance of the pair code with 6-bit code words? use an example to prove that your answer is correct. what is the hamming distance of the pair code on 100-bit code words? explain how you can again prove that your answer is correct ( avoid writing 100-bit numbers).how many bits can be corrected using a pair code with n-bit code words?

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
