run various mill operations.This was attempted on some Newcomen-type engines, but was mostly satisfied by both Savery andNewcomen engines pumping water up to a reservoir and then running the water through waterwheels. This overall scheme included additional energy conversions, each with non-unityefficiency. Watt developed rotating shaft output engines in the 1780s. Watt’s plan to use acrankshaft was delayed until the expiration of a patent for use of this device in 1794. As a result, hedeveloped and patented a double gear rotational drive in 1781. After 1794, the crankshaft andflywheel were generally used.incorporating historic engines into current instructionThe graphics, description of operation, and calculations presented in this article

We plan to make frequent enginemodifications out in the field which will change the cycle details, so please also make your model easy toadjust with additional p-V data. Hopefully with the help of your model, we will be able to see how makingsmall changes to the cycle affects work produced and thermal efficiency. To keep the model easy to use, weask that you: 1) treat the fuel-air mixture in the combustion chamber as
TechnologyEach region faces different challenges with managing and developing plans for energy security.For example, while there might be some similarity, China does not face the same challenges asthe United States. Similarly, the East African region has very different challenges from thosecountries. These technologies are being developed to solve problems for the regions whichidentified the need. Wind energy is a great source of electricity in the United States however itmay not work as well in East Africa1. Alternatively, solar power would be well suited for thetropical region which gets great amounts of sunlight.Technology maturity is another challenge. With increasing demand for oil from China, India,Brazil and other emerging nations, renewable
developmentalnetwork ties, mentor and mentee are linked by several types of ties (e.g., friendship, collaborator,and service on the same committees). These multiplex ties between mentor and mentee can bebeneficial as multiple relationships strengthen the mentor-mentee bond and provide differentvenues for episodic mentoring to emerge naturally. For instance, faculty may engage in multiplementoring episodes through co-teaching courses, working on departmental policies, and sharingcourse plans and grant applications. Furthermore, encouragement of multiplex ties is beneficialfor faculty whose areas of expertise are not redundant with those of their other departmentalmembers. In this regard, our women engineering faculty participants discussed how theirmentoring

All of the concepts that are proposed as part of the project are based uponresearch findings from STEM education research (described below). The plan is todisseminate the MSE apps through the Apple App store, but currently they run only onour many iPod test devices during the development and testing phase of the projectbecause of Apple’s development licensing restrictions. At the conclusion of the project,all materials will be placed on the NSF sponsored National Science Digital Library(NSDL).While much is known about more effective practices in STEM education, many barriersexist to
demand unique new competencies of professional engineers. In the context of the Sociology of Professions, the ASME Board of Governors’ position on licensure reflects an orientation consistent with industries’ interest in maintaining a large supply of low-cost engineering talent. This perspective is clearly not in the best interest of the engineering profession, as it will only contribute further to the commoditization of engineering services and the subordination of the engineer’s professional authority to a corporate entity.References1.

administered at the beginning of the studio project, itis expected that start-up adjustments and normalization of student attitudes would lower theoverall perception of the students. The perceptions for the junior-level courses and thedistributions between the two classes are very similar despite being implemented by entirelydifferent personnel. Such a result is a positive indicator of the benefits of the systematicimplementation plan described above. While the majority of student responses for all threeclasses are positive, a lower fraction of sophomores perceive value. There are several plausiblefactors that may contribute to the difference between sophomores and juniors. As the
ofwriting still provides a useful overview of the ways in which writing practices can supportlearning [47]. He reviews four hypotheses: 1) the initial act of writing itself brings forth newknowledge as writers allow ideas to flow; 2) learning occurs as writers move through therevision process, as writers organize, link, evaluate, and refine their ideas; 3) different genrestructures such as argument, compare/contrast, or analysis support learning by helping studentsmove through logical processes; and 4) learning occurs as students plan their writing and setgoals and sub-goals for problem solving. Klein notes that while each of these hypotheses havemerit, and some degree of empirical evidence existed at the time of his writing to support them,much

For instance, a research survey of graduate students, postdoctoral fellows and tenuretrack/tenured faculty found that more graduate student women than men (28.5% of women vs.7.2% of men) are concerned that a career in science will be detrimental to their plans for a family(Ecklund and Lincoln 2011: 4).xxiv For many women – and some men – these concerns persistbeyond the graduate experience. For example, a 2009 National Research Council of the NationalAcademy of Sciences report found that women who receive a doctorate in science andengineering are less likely than men to seek academic research positions, and are more likely todrop out of the academy before tenure when they do pursue a faculty position.xxv1 A November2009

I think that really falls to the teachers in those courses to create – push the students and create some innovative projects to incorporate with the criteria that they’re teaching.”According to the participants, incorporating more of these projects into the curriculum wouldhave the additional benefit of helping

”. It is a centrally planned and controlledsystem with relatively little flexibility to fluctuations in energy demand. As the nation and theeconomy becomes increasingly digital, energy demand is growing rapidly. For example, it isestimated that by 2015 around 60% of the total electrical load will be from chip technologies andautomated manufacturing versus 10% of the total in the 1990s 1. While the automotive industry is presently dependent on petroleum sources, the growingpresence of Plug-in Hybrid Electric (PHEV) and Battery Electric Vehicles (BEV) will begin toact as a stress upon the electrical grid by drawing resources during times of peak energy demand.A study from Oak Ridge National Laboratory finds that charging vehicles during off

Even if using a singlearchitecture for teaching, we always have to make an effort to contrast how the same processesor operations would be performed on other architecture.A very important aspect now is energy conservation, and the battle of semiconductor companiesis in terms of who can deliver the best performance using the least energy. This is also anotherdimension that goes beyond the traditional criteria to select a platform when planning amicrocontroller course[9].Last but not least, what are the platforms most used in industry that will give students acompetitive advantage when looking for

The geometry curriculum was based on the Texas Essential of Knowledge and Skills5(TEKS) and followed the scope and sequence set forth by the school district. The primaryresource for practice problems for the students was found in the Holt Geometry textbook15 Thegeometry scope and sequence had 12 total units with one unit specifically focused on spatialability and its application. The unit was seven class days in length, six of which were instructiondays. The unit began by introducing students to 3D figures using nets (developments) and crosssections

The obvious downside, which is not insignificant and is of major concern toadministrators because of the cost, is that I obviously make a large number of copies. Onepossible solution, though I have not tried it, is to have students buy a “course guide” that has anyhandouts or example problem statements all together in one package. This of course means thatthe entire course needs to be planned out well before the first day of class which is not alwayspossible.At least once in the quarter, usually near the end, I dedicate a class period to more formal groupwork where I will rearrange the class into groups (i.e. not just working with neighbors) and givethem problems from topics throughout the course
