We will compare theperformance on exam problems that are correlated with specific computing skills, such as asensitivity analysis of thermodynamic properties. We will compare exam questions with similaraspects from years before and after computing was introduced

students become frontline innovators, and how moreauthentic creative capacity measures might be developed. Flatline in Other Fields?For the sake of the engineering curriculum, we recommend researching changes in studentcreativity in other disciplines. Is the flatline phenomenon unique to engineering? Are theredisciplines that are effectively enhancing creativity? Looking into disciplines, such as science,technology, and mathematics, will be essential. We also plan to look into fields that areseemingly unrelated, with a focus on those fields traditionally labeled ‘creative’, such asadvertising, visual and performing arts, and creative writing. Through this research, we hope tolearn effective approaches, techniques

The mechanical engineering course combines an introduction to fundamentals in the areasof statics, stress analysis, dynamics, fluid mechanics, and thermodynamics with activitiesdesigned to give students a broad sense of the profession. An important project within thatcourse is an introductory computer-aided engineering (CAE) project.In the CAE project, students use Pro/ENGINEER, Pro/MECHANICA andPro/MANUFACTURING software from PTC to design, analyze and plan the manufacture of asimple two-headed wrench

Through the introduction of nano-particles, there is an increase in the rate ofcooling since the fluid is able to effectively absorb more heat from the engine.According to a recent study conducted by the U.S. Environmental Protection Agency (EPA),locomotive diesel engines contribute significantly to air pollution in many of our nation’s citiesand towns. Since control plans for on-road vehicle emissions have been put into effect,locomotives could become the primary source for dangerous air pollution in the country.
