In Lab Experiments:
1. Breadboard the MOSFET biasing circuit with two power supplies of Fig. 1.
2. Measure the lp-Vos and Id-Vos characteristics of the 2N7000 MOSFET for 0 Voss
2.5 V and 0 sVps s 10 V, using the test circuit shown in Fig. 1(b). Enter the collected
data in the data table.
3. Build and test the circuit for biasing the MOSFET designed in Prelab. 10 (Fig. 2).
Measure Vs, VG, Vp, Vas, Vps, Vdo, and Id. Adjust the component values so that the
given specifications are met.
Postlab: Submit a written report.
1. Plot Ip-Vos and ID-Vos characteristics of the 2N7000 MOSFET with Matlab and
determine go and r, at Ip = 4 mA from the slope of the measured characteristics.

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges"what's being bought" are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them"for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s . so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of events"s of length m and s of length n, each possibly containing an event more than once"and decides in time o(m + n) whether s is a subsequence of s.

Which statement is true of web-based social media? a.they allow consumers to interact with and update content. b.they cannot be updated easily, as compared to print media. c.they are expensive to produce and maintain, as compared to print and television. d.they can exist independent of the internet.

Apython programming question: assume s is a string of lower case characters. write a program that prints the number of times the string 'bob' occurs in s. for example, if s = 'azcbobobegghakl', then your program should print number of times bob occurs is: 2
