Oncethe muscles are compromised, the creature is challenging to control. As an example, the syringes had to bereset frequently on leaking muscles because the air volume in the system would slowly decrease.Furthermore, actuating the syringes rapidly can be fairly exhausting for the operator after a while due to theamount of friction caused by this. The silicone tubing also can cause issues, specifically withmaneuverability, because the weight and elastic force caused by the tubes can affect the movement of thecreature.(b) Prototype ActuationBefore production of the McKibben creature, each team must first

unlikely to collaborate and share ideas with peers or apply the knowledge aftergraduation. Thankfully, the data show there is a measured improvement of 20% in student“confidence” with the material. However, the population that gained the highest boost in“confidence” was not the extremes in terms of GPA and course grade, but instead students closerto the median. In terms of student GPA, students with a GPA between 3.0 and 4.0 saw thelargest increase in confidence following interaction with the power demonstrator board.Similarly, students who earned a B or B+ in the course had the largest change in confidence;27% and 25% respectively. This growth and comfort with the course material is valuable to thestudent, enabling more direct engagement of the
steady, cruising flight at various altitudes3-4. According to Figure 1(a), as altitudeincreases so does the thrust required for a given wing loading. Keeping in mind that lower altitudesare more ideal for planetary exploration, an altitude of 5km was chosen for further analysis. Figure1(b) presents the constraint analysis and solution space of the system at an altitude of 5 km. Thesolution space in Figure 1(b) provides the wing loading necessary for flight to be 30N/m2. Throughanalysis of the weight distributions of various gliders with similar flight capabilities trying to beachieved such as the AAI RQ-7 Shadow [3], the estimated total weight of the drone is 30 N, with astructural, equipment, and fuel weight of 135 N, 67.5 N, and 67.5 N
instructional technique. Another motivation was toprovide students with an "evaluation scale" they readily understood: the "A-B-C-D-F" grading scale. To clearlydelineate the "course" and "instructor" criteria, as well as to help focus students’ responses through the use ofsubsidiary questions, were additional factors motivating the design. Last, but certainly not least, was themotivation to clearly show how each calculation was performed, and to illustrate — in a graphical fashion —how a given course "stacked up" against other courses in its comparison group (and to clearly define the consti-tuents of each comparison group). A key challenge in the design of the new course & instructor evaluation instrument was not only thechoice of criteria

The matrix used in the remote laboratory at BTH has five mainnodes and ten main branches, Figure 3. The main nodes are denoted A, B, C, D and GND. Theground terminals of the function generators and the oscilloscope are connected to GND.

The data shown in Figure 4(a) was obtained from DC output of the lock-in amplifier by changing angle of the 2nd polarizer and various system gains were also applied.Then the system sensitivity was measured DC output of the lock-in amplifier using a fit of thedata as shown in Figure 4(b). We found the system sensitivity of 6.4429 V/Degree, which meansevery 10 millidegree of rotation gives about 64.429 mV VDC output.

component gas is at a partial temperature of the full temperature of the mixture.d. The equivalent molar weight of the mixture is the density weighted sum of the components.2. The thermal diffusivity is the conductivity k divided by the heat capacity (density *Cp). If thematerial A has a very low thermal diffusivity and material B a very high one, heat applied to oneside of both A & B will cause:a. The heat to spread more rapidly through A than Bb. Material B to absorb more heat than material A.c. Material A and B will behave the same way.d. Material B will transfer the heat more quickly than material B.3. A rod of material A has a larger Young’s modulus than a rod of material B with the samedimensions. If the two rods are both loaded with the
mixture contains two components: a solute (A) and a liquid solvent (B). The mixture is contacted in an agitated vessel with a second liquid solvent (C) that has two key properties: A dissolves in it, and B is immiscible or nearly immiscible with it. (For example, B may be water, C a hydrocarbon oil, and A a species that dissolves in both water and oil.) Some of the A transfers from B to C and then the B-rich phase (raffinate) and the C-rich phase (the extract) separate from each other in a settling tank. If the raffinate is then contacted with fresh C in another stage, more A will be transferred from it. This process can be repeated until essentially all of the A has been extracted from

Whenever possible, the lecture topics were tied to the concurrent designproject that emphasizes hands-on experience in the lab. At the same time, whenever possible,concepts/methods from lectures were incorporated into project activities to help the studentsmake the connections between theories learned from the classroom and their applications on areal-world system.A.

replace current day textbooks with toolkits forexceptional teaching (TExTs)11. A TExT would provide all the same resources currently providedby textbooks along with additional resources for both the student and the instructor. For students,in addition to written objectives, information and examples, the TExT would provide videos withcontent corresponding to the lectures of the traditional teaching approach. However, these videolectures would be used by the students outside of the classroom, ideally just prior to thecorresponding class meeting. For the instructor, the TExT would provide (a) slides and notes thatcould be used in class to briefly review the material from the readings and videos assigned forthat day, (b) a catalog of learning
