To receive a lettergrade of “B” for this portion of the course the student needed to demonstrate that their system Page 26.1597.8met the minimum project requirements within the allotted time slot.A formal project report on the project was due by Thursday at 5:00 pm of final exam week. Thereport requirements were given in exhaustive detail in the project handout and the grading metricfor the report is shown in Figure 9 below. EE-474/EE-574 Project Report Grading

In increasing orderof sophistication they are: a. Model as incompressible flow in a pipe, using steam density determined from turbine exhaust conditions b. Model as incompressible pipe flow, but account for compressibility by using steam density averaged between tube inlet (turbine exhaust) and tube exhaust conditions. This requires using the energy equation to determine the steam exhaust temperature, use of the steam tables, and a few cycles of iteration. c. Model as compressible, adiabatic, frictional constant area flow (Fanno flow); treat

The orange disk on the wall in the upper left is one of the hydrogen sensors. The two green lights on the wall-box indicate that the system is on, the actuator valve is open, and that gas is available for use. Two red lights directly below the green lights, not illuminated in this photo, indicate when the system is off and the actuator valve is closed.

The course is designedto inform students of four major dimensions of renewable energy development (See Figure 1),with particular emphasis being placed on ―bottom up‖ community-based energy production anddemand-related choices. The four major actors studied are: a) citizens; b) political andadministrative institutions; c) private businesses; and d) researchers. In a bottom up

code todetermine the best moves of different joints of this robot to pick and place an object from point Ato point B, so that the minimum energy is consumed in this process. To measure the energyconsumption, UNI-T UT230B-US Power Meter was used [14]. It is noted that the movementfrom point A to B can be done by involvement of different joints in different ways. For example,α 1 degree rotation of joint 1, followed by α 4 degree rotation of joint 4, and α 3 degree rotation ofjoint 3. Another possible way to move from point A to B may be α 2 degree rotation of joint 2,followed by α 4 degree rotation of joint 4, and α 6 degree rotation of joint 6. There are many waysto involve different joints of the robot for the same movement from A to B

Other benefits that permanent magnet motors provide are the Page 22.202.5following: a) Since the flux is produced by the permanent magnet, there is no need for anexternal flux control circuit, b) because there is no field circuit, the permanent magnet motordoes not have any field copper losses like shunt DC motors would have [17], c) since no fieldwindings are required, permanent magnet motors are smaller in size compared to shunt DCmotors [18]. The basic configuration and picture of a permanent magnet DC motor is shown inFigure 5
