activities are inincreasing demand in industry and education because modern tasks and products are morecomplicated than before and companies need effective collaboration in their teams to meet theirgoals [1]–[5]. Teams whose members are dependent of each other in their goals and tasksperform better than individuals [6]–[8]. Working in teams has the potential to provide a higherlevel of diversity, and teammates could learn from each other and exchange more opinions [3].Hence, effectively working in teams is a crucial ability for candidates seeking jobs, and recruiterscontinue to evaluate this ability [9], [10]. According to the Job Outlook survey performed by theNational Association of College and Employers (2010), the “ability to work in a team

“hands-on” academic programs, like those in engineering technology, require laboratory courses or components within courses to acquaint students with actual hardware components, instrumentation, and software. Breadboards are used to serve as a way of connecting devices in electrical and electronic programs. Breadboards like the one shown in Figure 1 are often used to make connections easier.

Jeremy was also given some literature to study, starting with atextbook on entropy4. Theoretical BackgroundNeural NetworksA neural network mimics the function of the human brain. It takes its inputs and processes themthrough a network of neurons, usually arranged in two or more layers. The neurons combineweighted inputs, add a bias and then apply a transfer function before giving their output as aninput for the next layer. Figure 1

Ideally, each student willcome out of the program understanding how everything that they studied fits together,rather than thinking of it as just a series of independent courses. This fits into our goal ofinterdisciplinary study and the view of security engineering as a discipline that is appliedto other fields. Individual courses in the program are described in detail below and asummary chart of all courses is provided in Table 1.

Finite Difference approach for formulation of heat transfer problemsThe finite difference method is based on replacing derivatives by differences. A heattransfer formula consists of a differential equation. In the finite difference method, thederivatives in the differential equations are replaced by differences. For example, it canbe shown that the finite difference formulation for a one-dimensional steady heatconduction is as shown in equations (1) and (2). Figure 1 is a schematic that clarifies thenotations used in equations (1) and (2). Equations (1) and (2) are derived

Twocomputer design and analysis modules are used to provide the basics of the engineering designprocess. Using these tools developed over the first 3 weeks, the students are tasked to design andbuild a bridge that can support the weight of their professor.Six class modules are developed and presented in detail. The modules include: 1) BridgeStructures and Components, 2) Strength of Materials, 3) Structural Analysis Basics, 4) StructuralDesign and Project Management, 5) Computer Design Process, and 6) Detailed ComputerDesign.

one pixel to the next. There are many ways to perform edgedetection. However, the majority of the methods may be grouped into two categories, thegradient-based methods and the Laplacian based methods. A gradient-based method detects theedges by looking for the maximum and minimum in the first derivative of the image. An edgehas the one-dimensional shape of a ramp and calculating the derivative of the image canhighlight its location. Clearly, the derivative shows a maximum located at the center of the edgein the original signal. This method of locating an edge is the characteristic of the “gradient filter”family of edge detection filters, which includes the Sobel method [1]. A pixel location isdeclared an edge location if the value of the

. Unfortunately, there is not as much emphasis placed on teaching at theundergraduate level, since universities are struggling to obtain funding from outsidesources, which is most easily gained through privately funded outside research4, 5. Thisdrive for external funding takes precedence over teaching and service, as well as stayingup-to-date with the developments in the field.The argument can be made that since industrial experience is required as a condition ofgaining tenure in engineering technology programs, there is no lack of practicalexperience. This argument fails to acknowledge two distinct groups of educators: 1) newgraduates who may not have the required experience at the beginning of their academiccareers 2) educators that achieved tenure but

As a result, it is a big challenge foran instructor to prepare lectures that integrate the business programming aspects of anyapplication along with the theoretical concepts. RecommendationsAfter teaching this course for the first time, it was obvious that a total revamp was neededin order to engage the students in the learning process. In order to make this courserelevant the instructor needed to gain a broad understanding of the field. The approachwas two-fold; confer with employers, and, collaborate with GIS instructors.1.

Florman defines engineering as the “art or science of making practicalapplication of the pure sciences.”1 By this definition, we can see that students ofengineering need to learn at least two disciplines: 1) “the pure sciences” and 2) “practicalapplication” of these sciences. Combine these two necessities with the imperative fromnearly every employer that engineers must learn communication skills, and we have quitea wealth of information to teach our students in four (or increasingly five or six) years. Inorder to meet each of these goals, we must have a concerted, self-reflective teachingstrategy.Here is where James Britton, et al. enter the picture, because their study TheDevelopment of Writing Abilities2 illuminates students’ learning

This discipline is the basis for an engaging mindset. HCI is an interdisciplinary methodology that involves skills from disciplines such aspsychology/cognitive science, engineering, informatics, computer science/software engineering,ergonomics, human factors, and social sciences4. Therefore, HCI is more closely aligned with user-centered development.

Further, state and federal authorities have createdvarious programs to introduce and implement new ways of instruction to enhance undergraduateeducation. Various national organizations aim towards this objective. For instance, theAmerican Society of Engineering Education (ASEE) is fully dedicated to promote engineeringand engineering technology education.1 The ASEE convenes an annual conference andexposition exclusively for this purpose.

In addition, we asked whether or not the chosen majorof students was independent of ethnicity by doing a chi-squared test of hypothesis.Finally, we explored the relative success of science majors versus non-science majors byusing a two-sample t-test to assess if the average cumulative GPA for Science majorsdiffers from the average cumulative GPA for non-science majors ResultsAs indicated in Table 1, the total number of undergraduate TWU students in Fall 2003was 7,273.

It uses asemi-random, or heuristic, search method to explore the design space. The initial runs of theGenetic Algorithm are used for exploring the design space and the later runs are used forexploitation or convergence. The ability to maintain a balance between exploration andexploitation makes the Genetic Algorithm less susceptible to the problems of local convergencethan many other stochastic algorithms.The Genetic Algorithm involves: 1.

The design objective was to create a mechanism that was bothdurable and performed with repeatability. An important constraint on the assignment wasto only use concepts of kinematics and kinetics that had been covered thus far in the classfor the design and analysis of the mechanism. The available concepts included 2-D and3-D rectilinear motion, including projectile motion, concepts of force, mass, andacceleration, including frictional forces, work, power, kinetic energy, potential energy,impact and systems of particles. Due to the aerodynamics of the ball and the smallvelocities involved in the experiment, aerodynamic drag was neglected

Other designs involved the use of a push or pull springs to drive the motion of the ball byconverting the spring’s potential energy into kinetic energy for the ball (Figure 2). Several otherdesigns employed some sort of an impact mechanism to drive the ball’s motion (see Figure 3 forone example). Other design concepts employed catapult-type construction. One such design useda stretched elastic rubber band to swing the golf bar upon release (Figure 4). Another catapultwas built entirely out of play LEGO and naturally generated a lot of interest from both

IntroductionIn episode 1410 of the “Engines of Our Ingenuity,”1 John Lienhard states, “The Greek word tecnh (pronounced techne) describes art and skill in making things. Tecnh is the work of a sculptor or a stonemason, a composer, or a clock-maker. Ology is the study or the lore of something. Technology is the knowledge of making things.
