Notes:
1. This syllabus may be changed by the instructor as
needed for good adademic practice. Use the "refresh"
or "reload" function on your browser.
2. Quizzes and tests are open book (must have a legally
obtained copy-no Xerox copies) OR one handwritten
page of notes. Calculator allowed.
3. There will be no make-up, or early exams given.
Attendance is required for all tests.
4. Americans with Disabilities Act: The University of
Texas at Arlington is on record as being committed to
both the spirit and letter of federal equal opportunity
legislation; reference Public Law 92-112 - The
Rehabilitation Act of 1973 as amended. With the
passage of federal legislation entitled Americans with
L01 Aug 25
12
Disabilities Act (ADA), pursuant to section 504 of the
Rehabilitation Act, there is renewed focus on providing this
population with the same opportunities enjoyed by all
citizens. As a faculty member, I am required by law to
provide "reasonable accommodations" to students with
disabilities, so as not to discriminate on the basis of that
disability. Student responsibility primarily rests with
informing faculty of their need for accommodation and in
providing authorized documentation through designated
administrative channels. Information regarding specific
diagnostic criteria and policies for obtaining academic
accommodations can be found at www.uta.edu/disability.
Also, you may visit the Office for Students with
Disabilities in room 102 of University Hall or call them at
(817) 272-3364.

5. Academic Integrity: It is the philosophy of The
University of Texas at Arlington that academic
dishonesty is a completely unacceptable mode of
conduct and will not be tolerated in any form. All
persons involved in academic dishonesty will be
disciplined in accordance with University regulations and
procedures. Discipline may include suspension or
expulsion from the University. "Scholastic dishonesty
includes but is not limited to cheating, plagiarism,
collusion, the submission for credit of any work or
materials that are attributable in whole or in part to
another person, taking an examination for another
person, any act designed to give unfair advantage to a
student or the attempt to commit such acts." (Regents’
Rules and Regulations, Series 50101, Section 2.2). See
http://www.uta.edu/studentaffairs/conduct/.

6. Submit a signed copy of
http://www.uta.edu/ee/COE%20Ethics%20Statement%
20Fall%2007.pdf (the COE Ethics policy). Review the
contents of this page and the website referenced in 5
above.
7. If identical material is submitted for grade by different
students, the grade earned will be divided among all
identical submissions.
8. A paper submitted for regrading will be compared to a
copy of the original paper. If the paper does not agree
with the original, points will be deducted.
9. Student Support Services Available: The University of
Texas at Arlington supports a variety of student
success programs to help you connect with the
University and achieve academic success. These
L01 Aug 25
15
programs include learning assistance, developmental
education, advising and mentoring, admission and
transition, and federally funded programs. Students
requiring assistance academically, personally, or socially
should contact the Office of Student Success Programs
at 817-272-6107 for more information and appropriate
referrals.
10. Final Review Week: A period of five class days prior to
the first day of final examinations in the long sessions
shall be designated as Final Review Week. The purpose
of this week is to allow students sufficient time to
prepare for final examinations. During this week, there
shall be no scheduled activities such as required field
trips or performances; and no instructor shall assign any
themes, research problems or exercises of similar
L01 Aug 25
16
scope that have a completion date during or following
this week unless specified in the class syllabus. During
Final Review Week, an instructor shall not give any
examinations constituting 10% or more of the final
grade, except makeup tests and laboratory
examinations. In addition, no instructor shall give any
portion of the final examination during Final Review
Week. Classes are held as scheduled during this week
and lectures and presentations may be given.
11. Librarian to Contact: See http://library.uta.edu/sel/ and
http://libguides.uta.edu/content.php?pid=3545
12. Electronic Communication Policy: A UTA listserv is being
established for EE 2303. All class communication will be
conducted via this list. To sign up, go to
https://listserv.uta.edu/archives/EE5340.html, click on
the link "Join or Leave EE5340", or send e-mail to
L01 Aug 25
17
listserv@listserv.uta.edu with the command "subscribe
EE5340 your_name" (without the quotes) in the body of
the message. You may receive communication from this
listserv at any email address you choose. If you have
questions, send email to ronc@uta.edu. In addition, the
University of Texas at Arlington has adopted the
University “MavMail” address as the sole official means
of communication with students. MavMail is used to
remind students of important deadlines, advertise
events and activities, and permit the University to
conduct official transactions exclusively by electronic
means. For example, important information concerning
registration, financial aid, payment of bills, and
graduation are now sent to students through the
MavMail system. All students are assigned a MavMail
account. Students are responsible for checking
L01 Aug 25
18
MavMail regularly. Information about activating and
using MavMail is available at
http://www.uta.edu/oit/email/. There is no additional
charge to students for using this account, and it remains
active even after they graduate from UT Arlington.
13. Grade Grievance Policy: Forms to report a grade
grievance are available in the EE Office.
