Back up your files regularly!
Email to yourself – can use GoogleDrive for larger files.
USB flash/jump drives (32GB for ~$20)
external USB hard drives, 1000GB for <$100
use synchronization software to replace only the files that were changed on your computer hard
drive or your external USB drive
for PCs try: SyncBack Freeware SyncBackFree V6.5.4.0 (see bottom of page or use
direct download page)
or Allway Sync
Time machine on the Mac
Your external drive might also come with synchronization software: more and more
manufacturers offer software/drives with encryption software included
Another option is to use on-line backup services, your files are then stored on an off-site server,
e.g.:
Carbonite
DropBox 2 GB are free!
Backup daily!
Keep file sizes manageable
•

large files are difficult to e-mail (size limits!)
take up lots of space on your computer (depends on your disk size)
backups are slow
File size issues can often be avoided:
make sure that images are not being stored at a resolution higher than the screen (or print)
resolution
typical print resolution is 200dpi (dots per inch), screen/projector resolution 96 dpi
size of projector image at most 1920 x 1200 = 2.3 mega pixels:
use image software to reduce image size/resolution
different sizes of graphic file formats vary in their file size: GIF or PNG format is appropriate for
images with sharp transitions and few colors (e.g., plots), JPEG is better for images with lots of
colors and smooth transitions, such as photographs;
Provide high quality images
the graphics in your thesis proposal/thesis need to be of high quality
images taken from the web often do not have high enough resolution, you perhaps need to
redraw the image
many journals now provide high resolution images on their websites, e.g. Mailloux et al., 2013
if you copy graphs from Adobe Acrobat, the resolution of your image depends on how large it
appears on the screen
you may scan images from printed materials, keep in mind what you want to use the image for
in case you have trouble lifting images from electronic sources, you can always take a screen
dump and paste it into an image processor, such as Paint or Photoshop
In Powerpoint, you can compress images to a certain resolution (click image and then go to
Format/Compress)
use the drawing toolbar to make cartoons yourself
PC/Macintosh compatibility issues
files created by the same applications on a Macintosh and PC are not always compatible,
although they should be
the problem is often that images are not transferred correctly or fonts are not recognized
tip: use basic fonts (e.g. Times Roman, Arial)
from a former version of the Microsoft website:
“When you add graphics to slides, be sure to use pictures saved in a graphics file format that is
common to both platforms, such as Portable Network Graphics (PNG), Joint Photographic
Experts Group (JPEG), or Graphic Interchange Format (GIF). If you are opening the presentation
on a computer that has PowerPoint, you’ll get the best results by using pictures saved in PNG
format. Otherwise, use a third-party graphics program to convert your pictures into JPEG or GIF
files.”
projection equipment at BC is PC based, if you create a file on a Mac, make sure it works fine on
a Windows PC before you give the presentation
another possibility is to store the presentation as Adobe PDF file, that format seems to be the
most compatible between different operating systems.
Bad and good Powerpoints:
Lots of examples on the web
avoid text-heavy slides (posters also)
Avoid complex Tables (e.g., don’t need most stats in presentations)
Keep plots neat and simple
Avoid distracting text
annotations and/or
images inside the graph pane.
Animations are useful, in
moderation: Avoid silly entry
and effects
Avoid overly complicated Tables

Remote control & File transfer issues
you will use a remote control for flipping from slide to slide
The remote control has a timer which will vibrate when you have 5 minutes and the again when
you have 2 minutes left.
The remote has a laser pointer as well
please deposit your PPTX and/or PDF file on the courseworks web page of EESC BC 3800/01
(under ‘shared files/mini conference’) before noon of the day of your presentation
Don’t use Prezi!!!! Only PDF or Powerpoint files are accepted
Use LastnameF.ppt as filename and add your Lastname, Firstname under ‘title’ when you post
the file
PLEASE don’t bring your presentation on a USB drive to class or download it from your mail
account to the presentation computer in the front – WE DON’T HAVE TIME FOR THIS!
During the mini conferences we will ask you to make comments on each other presentations in
writing; your advisor will channel those comments plus those of faculty back to you in writing
