to go for help
 If you make yourself visible in class and
during office hours, the professor may
remember you while grading
 Teaching is not professors only
responsibility, often the are researchers
and advisors as well, so give them the
benefit of the doubt

101

generated, initial and freehand sketches are
vital to the design process
 Freehand does not mean messy. Sketches
should display an adequate amount of detail,
and any pertinent notes/comments pertaining
to the drawing
 For instance, if a line is supposed to be straight,
make it as straight as possible. A square will not
pass for a circle.

122
9.7 Graphical Communication

Structures
 Traditional: One leader, who directs
subordinates. Leader typically is the
only one who “speaks”.
 Participative: Leader is closer to
individual workers.
 Flat: There is no “leader”. All members
are equal. The leadership “moves” with
the situation to the worker with the
most expertise in a given subject

130
11.5 Decisions within a Team
 Consensus: All team members agree
on a decision
 Majority Rule
 Minority/Committee decision

 Many different Experiences are available

245
21.2 Summer Jobs
 Even jobs such as baby-sitting and mowing
lawns is a place to start
 All jobs help develop basic employable skills
 Provide stepping stone to better, more career
related jobs
 Skills include teamwork, communication, and
problem solving
 Help you discover what working environments
you like

246
21.3 Volunteer
 Especially useful to freshmen and
sophomores to gain experience

 Provides a unique experience
 Challenging in many different areas
 To learn more
 Talk to professors that share similar interests

248
21.5 Internships
 Paid or unpaid experience for a set period of time
 Usually during the summer
 No obligations for future employment
 Sometimes they support other engineers
 Other times they are given individual projects
 No official evaluation or credit given
 Short term projects
 Obtain a description of these projects prior to employment
to assure it is of interest
 Great for students with time, curriculum, and location
constraints

249
21.6 Co-operative Education
 Cooperative Education is often the preferred form of
experimental Learning
 Co-ops are considered to be academic and are
administered by the college
 Assignments are directly related to field of study
 Detailed job descriptions are used to create the best possible
matches
 School and work are closely integrated
 Alternating terms of school with work at the same company
 Projects become more extensive throughout the experience
 Term in school followed by a term at work followed by a term
at school and so on

250
 Parallel co-ops is an alternative
 Students are partially enrolled in classes and spend 20 to
25 hours at work
 Difficulties arise in allowing ample time for both areas
 Sometimes a longer alternating approach is used
 Students work two consecutive semesters then attend
class for a semester or two
 Allows for longer projects
 Some schools use all three methods
 Co-ops are rarely summer only
 Break between work assignments is too long
 Requires a three or four semester commitment

251
 Advantages for Students

 Philosophy

256
22.1 What are Connections?
 Look closely at what engineers really are and
what they really do
 “liberal” comes from liberty, so that liberal
arts means “works befitting a free man”
 Need for a general education
 Developed because people have a need for a
strong, open mind in addition to a specialty in
order to be well-rounded
 Not trapped by cultural blind-spots

257
22.2 Why Study Liberal Arts?
 Liberal arts help improve your
broadness
 Look in many directions at once
 Questions about areas that do not have
pre-set answers
 Expected to be a leader

258
 The Arts Improve:
 Your Perspective
 See the “big picture”
 Your Balance
 Practice dealing with a variety of diverse ideas
 Your People Skills
 Be aware of things that modern tendencies
avoid or neglect

259
 The Arts Improve:
 Your Sense of Duty and Responsibility
 Elevate, integrate, and unify the standards of
the profession

 Use to run your programs and see the results
 Command History window
 Shows a history of the commands that have been
entered into the command window
 Launch Pad window
 Allows you to start applications and
demonstrations by clicking the icons in the
window

268
 Demonstration Programs
 >>demo
 Help Files
 >>help <command name>
 >>lookfor topic
 >>helpwin
 MATLAB is case sensitive
 Apple ≠ apple ≠ APPLE ≠ aPPle

269
 Helpful commands
 >>who
 Allows the user to see the variables currently in
memory
 >>clear
 Erase the memory
 >>clear <variable>
 Clears just that variable

270
 MATLAB has some predefined functions that
should not be used to name variables
 A few variable names to avoid:
 ans
 Inf
 NaN
 i
 j
 realmin

271
B.3 Symbolic Manipulations
 To declare variables as a symbol
 >> syms x y
 Algebraic expressions
 >>solve (x^2-4)
 Symbolic derivatives
 >>diff (y^3)
 Symbolic integrals
 >>int (sin(x))

272
B.4 Saving and Loading Files
 To find out the identity of your working
directory, type pwd (print working
directory)
 Use cd to change the working directory
 >>cd c:matlabmystuff
 The file can be saved using save at the
MATLAB prompt

273
B.4 Saving and Loading Files
 Use the command load followed by the
file name to retrieve your file.
 >>load my_workspace
 path lists the directories that MATLA
will search for files
 addpath <pathname> will add the
location to the path listing

274
B.5 Vectors
 A vector is simply a row or column of
numbers
 Vectors are enclosed in square brackets
 >>row_vector = [1 2 6 9 12]
 >>col_vector = [2;4;6;8;10]
 To change a column vector into a row
vector and vice versa, use transpose

275
B.5 Vectors
 For vectors to be added and subtracted,
they must be of the same type and size
 To multiply or divide vectors, special
MATLAB symbols must be used
 “.*” is used for multiplication
 “./” is used for division

276
B.6 Matrices
 A matrix is a group of numbers
arranged in columns and rows
 Each element in a matrix is identified by
the use of two numbers or indices
 The first index is the row number
 The second index is the column number
 MATLAB can extract an entire row or
column, or specific elements

277
B.7 Simultaneous Equations
 Put the equations to be solved into
standard form
 To solve for matrix x from Ax=b
 X=Ab

278
B.9 Plotting
 To generate linear xy plots use plot
 >>plot(x axis values, y axis values, ‘symbol
or line type’)
 Use hold on to plot multiple data sets
 The axes can be labeled using the
commands xlabel, ylabel, and title
 To generate multiple plots on a single
figure use subplot

279
B.9 Plotting
 Semi-log and log plots
 semilogx
 semilogy
 loglog

281

series of MATLAB commands that can
be saved to run later
 Select new, M-file to open the
programming editor
 Enter MATLAB commands just like you
would type them into the workspace
 Add comments by using the % symbol

282
B.10 Programming
 Save the file with a .m extension
 Remember to avoid file names that
MATLAB already uses
 The file can then be executed by typing
the file name at the MATLAB prompt

283
B.10 Programming
 Input commands
 To ask the user to input a number
 >>W=input(‘Enter a number to be used by the
program’)
