Aurel Systems Inc. offers a commercial dynamic process simulation program called CADSIM Plus™ (www.aurelsystems.com). At several places in the program sets of nonlinear equations must be solved or nonlinear functions must be minimized (for example, solving pressure flow networks, solving for independent variables given sets of user defined dependent variables, solving for both temperatures on a heat exchanger with condensation or flash).
Medication non-compliance is associated with poor outcomes in patients. Although different methods are currently used to measure compliance, the ability to translate this measure into a meaningful metric, which is interpretable for both methodologists and clinicians, has not yet been realized. Medication compliance has become an increasingly important area of research as policy makers perceive the extent and effect of the problem that non-compliance poses.
Semiconductor materials are essential for today’s fast growing electro-optic and computer industries and semiconductor crystal growth is a key stage in the manufacturing process. There is constant market pressure to increase the size and quality of crystals so that more and better devices can be put on a single wafer. The most widely used crystal growth technique is the Czochralski (Cz) method, in which a semiconductor crystal is grown at the tip of a seed-crystal while the seed is slowly extracted from a pool of molten material.
The Communications Security Establishment (CSE) is Canada’s national cryptologic agency. CSE is mandated to acquire and provide foreign signals intelligence and to provide advice, guidance and services to help ensure the protection of Government of Canada electronic information and information infrastructures. It also provides technical and operational assistance to federal law enforcement and security agencies. The intern’s research centred on developing a model, or clustering technique, that will enable CSE to predict communications activity.
Detecting ovarian cancer is, in general, difficult because of the lack of effective screening tests. If the disease is discovered when confined to the ovaries, surgery alone is curative in more than 90% of patients - however, in most patients, diagnosis only occurs after dissemination beyond the ovaries. In these cases, a combined treatment of surgery and chemotherapy is necessary. Unfortunately prognosis is grim and median survival is only 3 years despite treatment.
Teck Cominco Ltd. is a diversified mining, smelting and refining group, a world leader in the production of metallurgical coal and zinc and a major producer of copper and gold. The company was interested in investigating the dispersion of particulate matter from its Trail facility into the surrounding area under the influence of diffusion, advection by the wind and settling effects. In particular, the company was interested in estimates of yearly release rates from particular release points which are very difficult and costly to measure directly.
