    End of ISSAC Conference 

THURSDAY, JULY 30, 1992 

  NSF-sponsored workshop: Integrated Symbolic-Numeric Computing.

                       NSF-SPONSORED WORKSHOP 

A workshop, entitled "Integrated Symbolic-Numeric Computing,"
and supported by the U.S. National Science Foundation, will
be held on Thursday, July 30, at the same location as the ISSAC conference.  
The subject of the workshop is the emerging area of combined symbolic and 
numeric methods for scientific and engineering problem solving, with 
possibly the necessary use of high performance computing environments. 
The invited talks will cover the areas of numerical techniques for symbolic 
problems, symbolic techniques for numerical problems, and applications of 
symbolic--numeric methods, as cited in the proposal.  In addition, ample time 
will be available for impromptu presentations and discussions by the 
workshop attendees.  The workshop is open to the public with no registration

                           OTHER EVENTS

Reception and Barbecue:  
   A reception on Sunday evening and barbecue on Tuesday evening 
   are included in your full registration fee (not student fees).  
   Additional tickets can be purchased for non-registered
   persons or students for an extra  $18.

   During the conference, meals will be available at the Foothill Housing
   cafeteria.  The hours are: breakfast 7:15--9:00, lunch 11:30--1:30,
   dinner 5:00--6:30.  For attendees staying in the Foothill Housing on 
   campus, meals are included in the housing cost; meal tickets will be
   issued at check-in time.  Others may purchase individual meals with cash.

Business Meeting:  
   There will be a business meeting for SIGSAM on Monday evening after 

Discussion of ISSAC Issues:  A discussion of ISSAC organizational
   issues, as requested by J. von zur Gathen, will follow the business

                        LOCATION AND HOUSING

ISSAC-92 will be held on the campus of the University of California at
Berkeley.  Residence rooms will be available at the Foothill Student
Housing Complex, a modern (1.5 year old) facility on the north side of
the campus at 2700 Hearst Ave, Berkeley.  ISSAC-92 technical sessions will 
be held in the Sibley Auditorium of the Bechtel Engineering Center, a short 
walk from the residence halls.  

Special group rates are available including meals for the duration of 
the conference: $164.00 per person double occupancy, and $224.00 per 
person single occupancy.  These rooms are arranged in suites, with 4 
to 11 rooms per suite. Each suite has one or two lavatory/baths, linens 
and towels, and telephones.  We encourage you to request double occupancy 
rooms so that we may accommodate all the conference attendees on site.
This single room and board fee covers arrival for brunch on the afternoon 
of Sunday July 26, through departure after breakfast on the morning of 
Thursday, July 30.  There is no reduction for shorter stays or missed meals.

Persons arriving before Sunday may be accommodated at adjacent Stern Hall, 
an older dormitory, for a low daily rate.  However, we suggest that you 
consider staying in San Francisco or other tourist locations, or stay in 
an airport hotel at weekend rates.  

You may arrange private hotels accommodations in the area; in such cases, 
conference meals may be purchased for cash at the conference or at
nearby restaurants.  Prices quoted for hotels below are without
meals.  Call before June 26 and mention ISSAC-92 for these discount rates.

Here are some nearby hotels:

Hotel Durant, located at 2600 Durant Ave. Berkeley, CA 94704, is
easy walking distance to the conference.  Toll free: (800) 238-7268; 
local phone (510)  845-8981; FAX: (510) 486 8336.  Typical rates are: 
$75/single, $85/double.

The Shattuck Hotel, located at Shattuck Ave. and Allston Way in Berkeley,
is a long walk or a short shuttle bus ride to the conference site.
Toll free: (800) 237-5359; in California, (800) 742-8825; 
local phone (510) 845-7300.  Typical rates are:  $82/single, $97/double.

The (luxurious) Claremont Resort Hotel, is located at Ashby and Domingo
Aves., Oakland, CA 94623.  It is approximately 2 miles from the meeting. 
Call (800) 551-7266 reservations; FAX (510) 843-6239.  Typical rates 
are: $149 and up for single, $169 and up for double.


The University of California at Berkeley campus is about 45 minutes by
car from the San Francisco International Airport, and 30 minutes from
the Oakland International Airport.  Foothill Housing is at the North
East corner of the campus near the intersection of Hearst Ave. and
Gayley/LaLoma Road.  If you are driving a rental car from an airport
(all major rental car agencies have offices at both airports), ask for
direction and a map to Berkeley.

One recommended route from interstate highway 80 is to take the
University Ave. exit in Berkeley.  Follow University Ave. (East) until
a T at Oxford St.  Turn Left on Oxford then (almost immediately) right
on Hearst Ave.  Follow Hearst (uphill) just past Gayley/LaLoma (This
is one street which changes names as it crosses Hearst).  See the
signs for the registration area about 100 meters ahead and to your
right.  This address is 2700 Hearst.  The registration desk is through
the gate and to the right.  After hours, visit the registration desk
for Stern Hall: through the gate and straight ahead.

Since parking at registration is quite limited, you may have to park
behind the residence halls -- follow Hearst Ave up to parking lots on
your right.  You can then walk down to the registration desk. (You may
find it better to leave luggage in your car temporarily, since you
would then have to carry it back up to the rooms.)  Note that
if you intend to keep a car at the conference site, you must obtain a
parking permit and pay $15 for the week.

It is certainly not necessary to have a car during the conference.
If you are not driving from the airport, there are several bus services;
you may take any of them that will take you to Berkeley, but only
the Bay Porter Express (1-800-548-8811 or 415-467-1800) offers door-to-door
service from either airport (for about $15). Taxi service is also available
and may be less expensive for groups of 3 or more.  Public transportation 
via Bay Area Rapid Transit (BART) and shuttle busses at both ends is also 
available, but is time consuming.

AMTRAK (train) and Greyhound Bus service provide transportation
to Berkeley or nearby Oakland or Richmond.  A taxi from these stations
(for about $15) is the simplest way to reach the conference site.

                        ACTIVITIES IN THE AREA 

Berkeley, San Francisco, and other nearby areas provide an unparalleled 
opportunity for cultural and recreational pursuits.

San Francisco is justly regarded as the most scenic city in the United
States.  It is surrounded on three sides by the Pacific Ocean and 
San Francisco Bay.  Its buildings and streets, located on a succession
of steep hills, provide an unending series of exhilarating views.
The mountainous Marin Peninsula lies just across the Golden Gate Bridge, 
and the Berkeley area lies on the eastern edge of the bay.  

The Bay Area provides an abundance of cultural events through its
museums, theaters, symphonies, opera, ballet, jazz festivals, and other
performing arts.  There is a great variety of cultural events and 
an outstanding art museum on the Berkeley campus itself.  

Virtually every cuisine can be enjoyed in the famous restaurants of 
San Francisco and Berkeley.  The scenic Napa Valley, just a one hour
drive from Berkeley, produces some of the best wines of the United
States; most wineries welcome visitors and provide free tasting rooms.

The climate provides a year-round opportunity for such outdoor 
sports as sailing, tennis, and golf.  For a small fee conference attendees 
may also use the extensive campus recreational facilities.

Northern California enjoys a wealth of opportunity for those interested
in hiking, camping, bicycling, or just sight-seeing.  A few hours to 
the south of the Bay Area along the coast are Monterey, Carmel, and the 
Big Sur area where the coast range reaches the ocean.  To the north are the 
Mendocino coast, the redwood trees, and Mount Shasta.  In the Bay Area 
itself, Mount Diablo, Mount Tamalpais, Muir Woods, and the Point Reyes 
National Seashore provide many recreational facilities.  

ISSAC is not scheduling conference group tours, but tours to 
surrounding areas are readily available, and public transportation into 
San Francisco is fast and pleasant.


The weather in Berkeley is dominated by a maritime climate.
July is almost invariably dry and often cool, with morning and evening fog.
The average daily high temperature is 72F (22C); the average daily low is
54F (12C). A light sweater or jacket is advisable.
