[9] Just last year, General Electric (GE) moved their headquarters fromFairfield, CT to Boston, MA, 120 miles closer to MMA a possible source of new employees.One possible reason for the gender gap at MMA could be attributed to cultural stereotypes as astereotype may put pressure on a minority when it is judged against his/her group. Schmadar, T.et. al in their research showed that “activation of negative stereotypes can impair theperformance of stigmatized individuals on a
throughout history. Unlike the conventionalelectric power generation systems, in energy harvesting concept, fossil fuels are not used and thegeneration units might be decentralized. There are many sources for harvesting energy, such assolar, wind, ocean, hydro, electromagnetic, electrostatic, thermal, vibration, and human bodymotion. Even the energy of radio frequency waves, propagated due to television and radiobroadcasting in the environment, can be harvested. However, advanced technical methods shouldbe developed to increase the efficiency of devices in harvesting energy from variousenvironmentally friendly resources and converting them into electrical energy. Thesedevelopments have sparked interest in engineering community as well as the

The goal of providing this information was toenable the SME to assess if the object was potentially dangerous, not dangerous, or potentially sodangerous that perhaps divers should not be in their vicinity. It is important to note that the toplevel objectives provided to the student team were purposely generalized and not directive innature, in order to encourage non-traditional and out-of-box solutions and to avoid driving thestudent team toward a specific solution.

As seen in Figure 1below, applying heat temperatures that ranged from (150 to 180)°C [4] generated possibilities tohand-compress plastic waste at manageable pressures. Figure 1 Hand-Driven Compression Data [5]To achieve functional success, two challenges were presented during conceptual design for asystem that is capable of processing ocean plastic. The first challenge was the need to substitutethe HMC’s hand-compression method by use of a linear actuator, and the second challenge wasto integrate a heating process to soften plastic debris.

The use of MAESTRO in the graduateprogram affords the students greater insight into ship structural response to load effects that arenot always accurately analyzed by current manual methods (simple prismatic beam analysis). Inthe undergraduate program, the students use MAESTRO to develop a structural model as part oftheir senior ship design project. There has been difficulty in the undergraduate program in thedevelopment of a whole ship model, but the software allows the mid-portion of the ship structureto be easily created. In both the

effectiveness of an engineering curriculum is measured by how well studentscan apply and integrate their technical knowledge to solve real life problems. The currentengineering curriculum has been designed to only to provide the theory, however, it doesn’tprovide the integration of how this knowledge can be applied. The courses that are taken aspreparation for system engineering students include standard mechanical studies such asstatics, dynamics, and structural analysis, but also, computer software and hardwarecourses that study C programming, circuit analysis and electronics. These types ofcollegiate engineering classes that are taken on a general level in all system engineeringdisciplines, are supposed to provide the theory that is needed to build

The average grade washigher than the average cumulative GPA of the students completing the course.The perceived technical competencies were aligned with the learning objectives of the classes, aslisted in Table 3. Students were asked to indicate their competencies on a 7-point scale, where 1indicates very weak and 7 indicates very strong. Students’ perceptions of achieved technicalcompetencies were solid; their assessments of learning in the areas of fluid mechanicsfundamentals, experimental, and computational methods were generally above 6 on a 7-pointscale.
