Human-computer interaction

What is good and bad about the way UNIVERSAL TV REMOTE CONTROL works? Then list, (i) its functionality and (ii) the range of tasks a typical user would want to do using it. Is the functionality greater, equal, or less ? Compile the set of usability and user experience goals that will be useful in evaluating the device. Which is the most important one and explain why. Please think about interaction design.

Calculation and conversion of time given in hours, minutes and seconds

1- inputs a time duration in hours, minutes, and seconds; 2-calculates the equivalent total number of seconds; 3-recalculates the hours, minutes, and seconds from the total; 4-displays the values of the hours, minutes, seconds, and total seconds. Specific Requirements 1-The program must be otherwise formatted and documented 2-The program should contain a single method, main 3-The program should declare 4 variables, hours, minutes, seconds, and totalSeconds, all of type int. You may declare at most 1 additional variable for temporary usage. No other variable are allowed. 4- The program should declare and use exactly 2 constants, MIN_PER_HR and SEC_PER_MIN (minutes per hour and sec... click for more

Theory of Computation/Computer Science Problem

Consider the following three languages, all subsets of Σ* where Σ={a,b}: (1) L1 = {w l w is a word with odd number of a's} (2) L2 = {w l w is a word that ends with a b} (this question is asking for a word that ends with one b) (3) L3 = {w l w is a word with even length} From these: (a) Construct three DFA's (deterministic finite state automata's) that recognize these three languages (b) Construct a DFA (deterministic finite state automata) that recognizes L1 intersection L2 (c) Construct a DFA (deterministic finite state automata that recognizes L2 union L3) Please consult the attached file for the complete problem.

Theory of Computation/Mathematics/Computer Science Problem

Let x be an element of Σ+ be a word. Show that for all such x, the language L=x* is regular. Give an example of x such that the language: L subscript 2/3 = {uw l there exists a y an element of L, y=uvw, l u l = l v l = l wl } is not regular. Prove your answer. (note: l l is equal to the length) Please see the attached file for a more concise view of the problem.
