Mechatronics Systems Engineering (MSE)

Under the leadership of Chair, John Evans Professor, Dr. Kimon P. Valavanis in the Department of Electrical & Computer Engineering Department. The Daniel Felix Ritchie School of Engineering & Computer Science successfully completed the ABET accreditation in October of 2010 for the Mechatronics Systems Engineering (MSE) degree programs. ABET's positive observations and comments were on the strengths of the undergraduate common curriculum that is (enhanced) by the Mechatronics Systems Engineering program. The new PhD program in Mechatronic Systems Engineering (MSE) started on September 1, 2010. The Ritchie School of Engineering & Computer Science at the University of Denver, is the only University in the U.S.A that offers BS, M.Sc, and PhD degrees in Mechatronic Systems Engineering (MSE)!

Terminator bot mechatronics research

The Mechatronics Systems Engineering programs involve the integration of mechanical, electrical, and computer engineering to design complex systems to perform real-world tasks. The advent of inexpensive and relatively powerful microprocessors and microcontrollers has allowed almost any purely mechanical system (i.e. a car engine or a garage gate) to acquire some "intelligence" or to be controlled far more effectively than before. Mechatronic systems have become so pervasive and essential to everyday life that it is almost impossible to go through your day without using one. The ubiquitous presence of mechatronics creates a wide variety of employment and/or research opportunities for the student to master this multidisciplinary field, with the ability to integrate systems of components and people from differing engineering disciplines. The two main areas of specialization are Computer Systems and Mechanical Systems. These include courses in computer and mechanical engineering accompanied by a series of control courses and machine learning. Furthermore, the program offers research opportunities in the areas of robotics and unmanned systems, which allow for a deeper understanding of the mechatronics principles and give "hands-on" experience to the students. Examples of student projects range from model cars controlled by smartphones, automated landing platforms for small helicopters, to miniature radar systems and swarms of robots.

Enhancing Physical and Mental Abilities through Medical Engineering

The field of biomedical devices is expanding its role into therapeutics through local medication and treatments. Engineers, computer scientists and medical researchers are strengthening their collaborations to develop smarter joints, smarter implants, smarter artificial organs, and smarter organ repair, while tracking and understanding the complex connections within the human brain that could result in new therapies for Down Syndrome, Autism, Parkinson's Disease, and Alzheimer's Disease. Through medical engineering, the Ritchie School of Engineering & Computer Science faculty and students are developing transformative technologies that will result in life style management for the elderly and disabled, and new medical and diagnostic technologies for the treatment of neuro-psychiatric conditions.  

A team of senior DU engineering and computer science students were selected as one of six finalists to compete in a national design project sponsored by the American Society of Mechanical Engineering. The students, in collaboration with Craig Hospital and faculty across three academic departments, have developed a low-cost device to control a computer or iPad using eye motions, allowing paraplegic patients with traumatic brain or spinal cord injuries the ability to communicate electronically. The students' design will reduce the purchase price for the device from over $5,000 to a little over $100 per unit, thereby making the technology available to virtually everyone who needs it. The competition will took place this summer at the ASME Summer Bioengineering Conference in Puerto Rico.

DU Aerosol Group

Orion Plane for DU Aerosol Research

John Evans Professor Dr.Wilson leads the the University of Denver Aerosol Group. This research group develops and builds instruments and sampling inlets that we and other groups then use to study aerosols. Most of our measurements are made from aircraft platforms. Aerosols are collections of particles suspended in gas. The atmospheric aerosol comes from natural processes and human activities. The particles found in the air are very diverse in origin and chemical composition as the following examples show. Near the seashore, salt particles are abundant. Down wind of volcanic eruptions, we often find rocks, ash and sulfuric acid particles. High up in the atmosphere, meteors leave tiny debris particles in their wake as they burn up. We often live with the particulate results of combustion, construction and industry. In some places, the aerosol strongly resembles gasoline. Denver's brown cloud contains contributions from sources including the sand used on the streets, combustion products and particles formed from combustion products. SO2 emitted by power plants and other sources is oxidized to sulfuric acid that forms particles in the atmosphere. The concentration and size of atmospheric particles also vary dramatically. In the stratosphere, we often find fewer than 10 particles/cm3, but near a poorly designed or maintained diesel engine, the concentration can exceed a million particles/cm3. We measure particle diameters from 4 nm (1 nm= 10-9m) to 10 micrometer (1 micrometer = 10-6m).

Aerosol can affect many things we care about from human health to the manufacture of integrated circuits. The DU Aerosol Group has frequently studied the role of particles in stratospheric ozone depletion and in global climate change. We also study the sources and formation of pollution particles in urban and industrial settings, the emissions of aircraft and rockets and the processes that maintain the stratospheric aerosol. Many of these phenomena occur over a large scale, and we have made measurements at altitudes from sea level to over 70,000 ft (20 km). Our instruments have flown on NASA's ER-2, WB-57f and DC-8 research aircraft, NCAR's Gulfstream V. The German DLR has flown our instruments on their Falcon. The DU Low Turbulence Inlet is flown on the NOAA WP-3D, the NCAR C-130 and the UK Met Office and the Natural Environment Research Council FAAM aircraft (BAe-146). We have gone to Sweden, Chile, New Zealand, Australia, Alaska, Maine, California, the Virgin Islands, Japan, Costa Rica and points in between in pursuit of particles. Our instruments have gone to the North Pole and Antarctica without us.

Our instruments use light scattered from individual particles or controlled condensation of vapors on small particles followed by light scattering to tell us how many particles there are and how big they are. Our instruments and inlets are autonomous and computer controlled. They have passed the air-worthiness requirements of Lockheed-Martin, NASA, NOAA and NCAR, BAe Systems.
