Assume you have created a mechanical arm that can hold a pen. The arm can perform the following

tasks:

§ Lower the pen to a piece of paper.
§ Raise the pen from the paper.
§ Move the pen one inch along a straight line. (If the pen is lowered, this action draws a one-inch line from left to right; if the pen is raised, this action just repositions the pen one inch to the right.)
§ Turn 90 degrees to the right.
§ Draw a circle that is one inch in diameter.
Draw a structured flowchart or write pseudocode describing the logic that would cause the arm to draw the following:
a. a one-inch square
b. a two-inch by one-inch rectangle
c. a string of three beads

Creating "smart interfaces" in all sectors of industry, government, and the public arena is one of the fastest growing hct areas. these interfaces model, interpret, and analyze such human characteristics as speech, gesture, and vision. the field of biometrics, in which humans authenticate themselves to machines, is an area of considerable interest to hct practitioners. fingerprint scans are one of the most frequently used biometric options, and this article, biometric student identification: practical solutions for accountability & security in schools, makes a case for the implementation of fingerprint scans in schools. critique the article, and answer the following questions: according to the author, what are the main benefits of adopting fingerprint scans in schools for student identification? according to the author, what are the main drawbacks of adopting fingerprint scans in schools for student identification? do you agree with the author's assessment of the pl

Technician a says that with self-adjusting clutch systems, the release bearing constantly rotates. technician b says that the ball bearing portion of the release bearing should be lubricated with high-temperature grease during routine maintenance. which technician is correct?

Write pseudocode to represent the logic of a program that allows the user to enter a value. the program multiplies the value by 10 and outputs the result.
