SIAM Conference on Applications of Dynamical Systems (DS19)

General Information

Standard Audio-Visual Set-up in Meeting Rooms

SIAM does not provide computers for any speaker. When giving an electronic presentation, speakers must provide their own computers. SIAM is not responsible for the safety and security of speakers’ computers.

A data (LCD) projector and screen will be provided in all technical session meeting rooms. The data projectors support both VGA and HDMI connections. Presenters requiring an alternate connection must provide their own adaptor.

All speakers should review SIAM’s AV Policy prior to the pre-registration deadline.


Complimentary wireless internet access will be available in the guest rooms, public areas, and meeting space of the Cliff Lodge.

Email stations will also be available during registration hours.

Local Area

Please visit the Visit Salt Lake website for local tourist information. Check out the Salt Lake City’s visitor guide here. You can also visit Snowbird's website for more information. 

The average temperature in Snowbird during May varies between 33° F (1° C) and 52° F (11°C).  Please remember that meeting room temperatures and personal comfort zones vary widely. It is recommended that you bring a sweater or jacket to the sessions.


All of the lodging rooms in the Cliff Lodge, Lodge at Snowbird and The Inn have complimentary humidifiers.

Altitude Awareness

Important Information for visitors not accustomed to Snowbird’s high altitude: Utah’s Wasatch Mountains are among the most beautiful in America and we hope you will enjoy every minute of your visit. But some of the very features which make the high country so attractive may cause problems unless you recognize and know how to prevent them. Here’s why:

As you go higher, barometric pressure decreases, the air is thinner and less oxygen is available.  It’s also colder and drier, and the ultraviolet rays from the sun are stronger. Each of these changes may have unpleasant effects on your body.


Many popular resorts are 8,000 to 9,500 feet above sea level (Snowbird’s base is 7,900 feet), and the mountain summits rise more than 3,000 feet higher. You will probably notice that your breathing is faster or deeper and you may feel short of breath, especially when you exercise. This is the body’s first and most effective response to altitude.  You heart is likely to beat faster also; this too, is a helpful normal reaction.

However, you may also develop a headache, a touch of nausea, or unusual tiredness; some people even have trouble sleeping. Depending on the altitude, 20% to 30% of all visitors from near sea level have one or several of these symptoms, which we call acute mountain sickness or AMS. Children are slightly more susceptible; the older you are, the less likely you are to be affected.

These symptoms usually go away in a day or two. If they grow worse, or if you are worried, be sure to consult a doctor. If you develop a worsening cough, increasing shortness of breath, or feel like you have fluid in your lungs, see a doctor at once! Altitude illness, though usually minor, can become serious quite rapidly, so don’t take it lightly or try to tough it out!

Before you leave home, you can do a few things to decrease the effects of altitude. Our studies show that spending two nights at a modest altitude like 5,000 feet decreases symptoms when you go higher. Eat more foods which are high in carbohydrates, drink more water, and take less salt. Your doctor may be able to prescribe medication that will assist in lessening symptoms.

Once you arrive, take it easy for the first day or two. Reduce alcohol, caffeine, and salty foods. Drink more water than usual. Salt causes your body to retain fluid, which increases the severity of altitude illness.

Above all – listen to your body! Don’t push. If you feel worse and worse, get help! Minor altitude symptoms occasionally become life threatening.


The sun has more power in thin air, and a bad sunburn can spoil your stay. No matter how tanned you may be, use a protective cream. “Cold sores” are aggravated at altitude but might be prevented by various medications which your doctor can prescribe. Snow blindness – which is sunburn of the eyes – is a real danger, especially on new snow, and even on foggy or cloudy days. Wear sun glasses or goggles with ultraviolet protection.

Temperature falls about three degrees Fahrenheit for every 1,000 feet of altitude, and it can get cold very fast.  Take extra clothes. Hypothermia (low body temperature) can occur even in the summer if you are wet or windchilled, hungry, tired, or poorly dressed. The warning signs are clumsiness, trouble thinking or talking clearly, irritability, and confusion.  Watch for these in each other.  If in doubt, stop, warm up, eat and drink, -- and if necessary send for help.


The crisp mountain air is exhilarating, but it’s also very dry. You lose much more water than you realize in exhaled air and from sweating. It’s very important to maintain the body’s water level, so drink two or three times more than you usually drink. Fill your canteen or water bottle in the hotel. Don’t drink from streams. Juices and water are better than tea or coffee or alcohol. Remember that at high altitudes, one alcoholic drink does the work of two.


Accidents can happen at any time to anyone, but they are more common when you are cold, tired, and hungry. Remember that lack of oxygen can blunt your judgment, leading you to do foolish things. Whether hiking, skiing, biking, swimming, or playing tennis, give your body plenty of food and water to function efficiently. Don’t keep going when you are very tired; quit while you’re ahead.


Of course, you are as likely to get a cold or flu or stomach trouble in the mountains as you are at home. But altitude illness feels very much like flu, or a hangover, and it can be a lot more serious. If you have any doubt, get medical help. Don’t let ignorance or carelessness spoil your stay. There is a great personal joy, beauty, and spiritual peace to be discovered in the mountains. Treat yourself with respect and enjoy your visit.

Helpful Hints

Leading the applied mathematics community . . . Join SIAM and save!

SIAM members save up to $140 on full registration for the SIAM conference on Applications of Dynamical Systems (DS19)! Join your peers in supporting the premier professional society for applied mathematicians and computational scientists. SIAM members receive subscriptions to SIAM Review, SIAM Unwrapped and SIAM News and enjoy substantial discounts on SIAM books, journal subscriptions, and conference registrations.

If you are not a SIAM member and do not join SIAM before you register for the conference, you can pay the non-member rate and still apply the difference between what you paid for the conference and what a member would have paid ($140 for a non-member) towards a SIAM membership. After you register for the conference, contact SIAM Customer Service for details about membership or join at the registration desk at the conference.

If you are a SIAM member, it only costs $15 to join the SIAM Activity Group on Dynamical Systems (SIAG/DS). As a SIAG/DS member, you are eligible for an additional $15 discount on this conference. As the total price of membership plus conference registration is the same, you might want to consider joining the activity group.

Any student who registers as a non-member will automatically be given a free membership in SIAM, so please ensure that your contact information and online profile are complete when you register.

Visa Information

International attendees at conferences in the U.S. may already be aware that there have been changes to the visa program for scientific visitors, which affect even people from visa waiver countries. The website, maintained by The National Academies, provides guidance on obtaining the necessary documents. 

As of January 12, 2009, a valid ESTA approval is required for all Visa Waiver Program (VWP) to travel to the United States. Please visit the Visa Waiver Program for additional information and procedures regarding the visa waiver program as maintained by the U.S. Department of State.
