Write a method that takes three numerical String values and sums their values. For example, the call sumStrings("1", "5", "7") would return 13. This is done in Java.

You have just been hired as an information security engineer for a large, multi-international corporation. unfortunately, your company has suffered multiple security breaches that have threatened customers' trust in the fact that their confidential data and financial assets are private and secured. credit-card information was compromised by an attack that infiltrated the network through a vulnerable wireless connection within the organization. the other breach was an inside job where personal data was stolen because of weak access-control policies within the organization that allowed an unauthorized individual access to valuable data. your job is to develop a risk-management policy that addresses the two security breaches and how to mitigate these risks.requirementswrite a brief description of the case study. it requires two to three pages, based upon the apa style of writing. use transition words; a thesis statement; an introduction, body, and conclusion; and a reference page with at least two references. use a double-spaced, arial font, size 12.

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
