In the case of the UC2system, the global clock is set at 11.0592 MHz which results in a maximum operationalspeed of over 300,000 rpm for a typical 512 slot codewheel. As illustrated in Figure 6, atwo-bit shift register employing D-type flipflops is used to detect transitions on channelsA and B.By way of example, a rising edge on channel A is detected when enc_dec0.q andenc_dec1.q are “1” and “0” respectively. The transitions between the various statesillustrated in Figure 5 can be decoded by analyzing the outputs of the four D-typeflipflops as shown in Table 1 below.State Transition Encoder Signals Flipflop outputs: enc_decX.q Past

Iowa State UniversityAbstractAs evidenced by students’ inability to explain their solutions, abstract concepts without directphysical representations in engineering are difficult to grasp because they lack direct sensory,physical, or perceptual referents. In this pilot study, we investigate whether visual aids helpstudents better understand abstract concepts and improve their learning outcomes. Specifically,in the context of the (Q, r) model in the inventory control theory, we first develop visual aids forlearning and teaching, i.e., the animation of line plots that show the evolution of key quantities inthe (Q, r) model over time. We then plan to use a paired t-test to see if there is any differencebetween the students’ scores in the pre-test

Forexample in the materials course, students learn about the thermal properties of materialsfrom the atomic viewpoint. Generally, the heat capacity, coefficient of thermalexpansion, and the thermal conductivity are discussed.7 Students are able to describe howand why thermal conduction takes place in metals and insulators as a function oftemperature. The one-dimensional heat conduction equation is used as a means of examiningthe changes in the thermal conductivity, k of various materials. ∂Q ∂T = − kA

angular velocity and rotation about a fixedaxis, the military tank shows even more value illustrating rotating reference frames and theconcepts of relative motion. For planar motion, the military tank can be thought of as twodistinct reference frames – the chassis reference frame and the turret/barrel reference frame.Students can relate to these two distinct reference frames because they already know theindependent motion of the turret with respect to the chassis. If the chassis (reference frame N)remains fixed to the ground and does not rotate but the turret (reference frame T) is free to rotate,the relative motion of two points, P and Q on the turret can be discussed (Figure 4). By fixingthe chassis of the tank to the ground, we can establish a

While most of the research ondiversity in computing focuses on gender and race/ethnicity, some interpret diversity in otherways. Undergraduate students are stakeholders in the assessment of cybersecurity as a diverseand inclusive subfield of computing--as they may or may not consider these concepts as theymake curricular and career decisions. A goal of the study is to enrich our understanding ofdiversity perspectives in the field, and so we sought complexity of interpretation over anarrowing or codifying of viewpoints.

From thisbasis of understanding, an additional load S is included in both load sequences to discuss itsinfluence on the displacement expression. This leads to a general understanding of the influencethat any number of additional loads would have on the displacement expression, and that theeffect of the load Q remains unchanged as these loads are applied.

The second objective is to examine whethersuch epistemological beliefs are related to student academic outcomes among first yearengineering students.This study focuses on students in introductory engineering courses for two reasons. First,introductory STEM (including engineering) courses are often large, posing difficulties forinstructors and students to closely examine and discuss concepts and knowledge covered in thecourses.

. VSA’s would be an ideal addition to any undergraduate communicationslaboratory because of their ability to investigate the many types of signals prevalent today.Unfortunately, most VSA’s are priced well beyond the budgets of typical undergraduate ECEdepartments. This paper describes a novel low-cost VSA that uses basic PC data acquisition(DAQ) cards to capture signals of interest and real-time processing of signals with LabVIEWand MATLAB. This VSA system provides a user interface that has much of the basicfunctionality of standard hardware VSAs, but with the limitation that bandwidth is constrainedby the sampling rate of the DAQ. The system provides real-time plots of I/Q constellations. Wedescribe the user interface as well as example
