Title:
An Improved Parametric Side-Vertex Triangle Mesh Interpolant
Abstract:
There are many schemes for fitting triangular surface patches
to a triangular net of data. In general, local schemes
produce surfaces with poor surface quality. Although variational
techniques construct surfaces of higher quality, such techniques
tend to be computationally expensive. In this paper, I will
present modifications to Nielson's side-vertex method that improve
its surface quality without resorting to variational techniques.

COMPUTER SCIENCE SEMINAR



                    -Tuesday, May 12, 1998



Daniela  Rosu,  Georgia  Institute  of Technology, will

speak  on  ``FARA  -  A  Framework for Dynamic Resource

Allocation for Adaptive Real-Time Applications''.



TIME:                10:30-12:00 noon



ROOM:                DC 1302



ABSTRACT



Runtime   adaptation   and  resource  allocation  (ARA)

decisions  are  required  in  both  embedded  and  open

systems  when a new application arrives into the system

or when a change occurs in the resource availability or

in   the   resource   needs   of   a  currently  active

application.    Previous  research  concerning  on-line

adaptation  for  real-time  applications  has only been

interested   in   achieving   acceptable  steady  state

performance.   We   submit   that   on-line  adaptation

decisions  must  also  consider  the performance of the

application  during  its  transition  to  the  targeted

steady  state.  This  is  because  ARA  decisions might

result  in  delays  and  overheads  that can affect the

application performance during transition times.



FARA   is  a  Framework  for  Adaptation  and  Resource

Allocation  that  addresses  the  overall impact of ARA

decisions  on application performance. FARA is designed

to  support  the  development  of  resource  allocation

infrastructures in systems running multiple independent

applications.   FARA   enables   the   development   of

allocation  and  adaptation  heuristics  that result in

steady state improvements while exhibiting low decision

and enactment overheads. This is achieved by using rich

information  about  the adaptation capabilities of each

application  in  the  system  and  by  using  effective

mechanisms for decision support.



The   talk  will  present  the  models  and  mechanisms

embedded  in  FARA  and the manner in which they can be

used   to   reduce  the  impact  of  ARA  decisions  on

application  performance  during  the transition to the

targeted steady state.

                          Unix Tutorial Part II



                            Unix Shell Basics

 Now  that you are able  to send mail and  read news all around  the world,

you want to  get more from your  UNIX account.   Let us show you how  to get

Unix to do more work for you!

 This  tutorial is intended  for users with  some experience with  UNIX and

will be  held  in an  X-terminal lab  so that  participants can  immediately

experiment with the material being discussed.   Upon your completion of this

tutorial, you  will be able to  use files, directories,  redirection, pipes,

and apply filters.  Also, some  of the advanced command-line features of tcsh

will be revealed.

 Math students  should be sure to have their  accounts activated in MC3011,

and temporary accounts will be available to non-math students.



                Tuesday 9 June and Thursday 11 June, 1998
