Almost half of industry and organizations over the past decades into the the industrial revenues came from successive projects with ex- schools. These efforts include the mathematic modeling weeks, isting customers; while an additional 60 new customers joined multi-day events in which groups of students, instructors, and us from very diverse sectors. This clearly demonstrates the capa- student teachers get together to work on externally generated bilities, economic relevancy, and currency of the research topics problems. A very nice encouragement to continue this activity being pursued at ITWM. The revenue forecasts are optimistic, and engagement in the same direction came in the form of win- the employees are highly motivated for new challenges, and ning the top prize in the “Schools meet Science” competition we anticipate a resurgence of economic growth in 2012.
