To evaluate its effectiveness,experiments were conducted in which the customary lectures were replaced by use of this instructional software.Students who used the superposition software were compared to students in five other Mechanics of Materialssections on the basis of (a) score on a superposition problem included in the common final exam, (b) total score onthe common final exam, and (c) a survey questionnaire consisting of a number of subjective rating items. Thosestudents who used the superposition software were statistically comparable to the other students on all theseoutcome measures. In addition, there was evidence

MethodsThe Kaiser design process involves calculating the Fourier series of the ideal filter and then multiplying itwith a Kaiser window that best fits the filter specifications. Filter specifications are (Figure 2(b)): Filtertype: can be low-pass, high-pass, stop-band or pass-band; Wp1, Ws1 – pass-band and stop-band edge cut-off frequencies, respectively; Wp2, Ws2 – second pass-band and stop-band
. Atconcentrations above that range the times continued to decrease but at a much lesser rate. Geltemperature (Figure 3(b)) showed a similar pattern of little change at the higher concentrations,reaching a plateau around 185 C. The inflection temperature pattern was not as clear.The gel time and temperature behavior reflect the molecular make up of the vinyl ester. Asoriginally made, the resin is much too viscous to be used for composite materials. Consequently,it is diluted with styrene monomer. (It is the styrene monomer that gives polyester resins thecharacteristic odor that many people associate with “fiberglass” composites 2.) Fortunately, thestyrene monomer enters into the gel and cure reactions and thus is a reactive diluent. As part ofthe final

The giventooth height is 115µm, and the tooth width, b, was calculated using the formula 5: 2C b= (2) σ 0.2 mϕrWhere C is the applied torque, σ0.2 is the elastic limit stress (0.2% of plastic deformation), m isthe tooth modulus, φ is the fatigue factor, and r is the gear radius. The gears are to be supportedon axles made of steel of diameters 160 and 100µm for the gear and pinion respectively, bothwith

They help to reinforce thepurpose of the writing consultant presentation, and provide a way for instructors to assesswhether the lesson has come across correctly.3. Midterm PortfolioThis project (Attachment B) asks students to assemble their best and weakest lab report andrespond briefly in writing to the reports’ efficacy. It also gives students an option to rewrite theirworst lab report based on the writing consultant’s comments if they desired. The assembly of theportfolio counts for that week’s “one-minute” paper, and the rewritten paper (if submitted) isregraded and the higher grade recorded in the grade book.

In this case, we obtain an amorphous microstructure that is entirely differently from one that is a result of solidification. The photograph below is a scanning electron microscope picture of an amorphous alloy consisting of Fe-Zr-B-Cu metals. (Most engineering materials are not composed of a single element or compound, but rather of a complex mixture of a number of elements. A substance which contains a mixture of elements is referred to as an alloy.) The matrix is amorphous, but upon reheating, small crystallites of Fe being to nucleate out of

discounted at arisk-rate, and inflation must be handled consistently. The rule to measure the future of a projectis simple too: “An investment is worth if it has a positive NPV, and if the investment has anegative NPV, it should be rejected.” 1 These rules have many times killed projects before theyare even born.In order to understand better this topic, lets say BDS Corporation is planning to buy land for$120,000 to develop a condominium. The intention of the company is to build seven (7)apartments type A or 11 apartments type B. Current value of apartment A is $ 97,000 and type Bis 105,000 and the cost are 80,000 and 95,000 respectively. Could the company build the projectthis year?Because the project will be build this year, time T = 0. Table No
discipline in the solution step calculations was indeed hindering the students. Upon further examination, the author was able to simplify the needed discipline into somevery basic, yet crucial, concepts. These distilled and clarified ideas, termed “Solution StepDiscipline” (“SSD”), are: 1. Solution Steps form a logical chain. 2. Solution Steps proceed down the page. 3. Solution Steps are to be understandable to a knowledgeable reader. 4. Each Solution Step must be one and only one of: A. Starting Equation B. Substitution C.

At the Destination Download Station, the robot receives commands serially.These commands are intersection codes that define a path from point A to point B. Afterpower to the robot is recycled, (this forces use of the PIC12F675 EEPROM to storeintersection codes) the robot must travel the prescribed path. Sensor outputs are analog andmust be processed either by the comparator or the ADC. The timers are used for timingcritical issues such as PWM generation for motor drive and, in some implementations,turning at intersections.

students graciously obliged. For the testing of the VaNTH learning modules, studentswere randomly assigned to either a trial group or the control group by drawing the assignmentslip from a hat. The trial group used the VaNTH website material for the exercise, and thecontrol group used a hardcopy paper version of the same material. The course instructorrecorded the students’ names in each group, but also assigned a random two-digit ID number toeach student with no correlation between the ID number and the group assignment. This IDnumber was subsequently used for all data to assure anonymity. Since there were three modulestested, this random assignment procedure was conducted three times during the semester,resulting in Groups A and B, C and D, and

Turing writes: The new form of the problem can be described in terms of a game which we call the 'imitation game'. It is played with three people, a man (A), a woman (B), and an interrogator (C) who may be of either sex. The interrogator stays in a room apart from the other two. The object of the game for the interrogator is to determine which of the other two is the man and which is the woman. He knows them by

systems has been shown a successful start for quickintroduction of rotating mechanical systems to students at TAMUK. Figure 2 illustrates the twosystems and Table 2 gives corresponding variables and equations. By comparing the two systemsby Figure 2 and Table 2, students can quickly and effectively get the concepts of angularposition, speed, and acceleration, the meanings of inertia and torque, and Newton’s law inrotation systems. Then, based on Newton’s law in rotation, a simple example such as a solidcylinder can be used for calculation of inertia to let students more clearly understand the conceptof inertia and factors that can affect it. x a) A linear motion system b) A
