. Samples printed using the 3D printer, the advantages of the recyclingsystem, the difficulties encountered during the design and development, and recommendationsfor future recycling system design are presented and discussed.1. IntroductionRapid prototyping (RP) consists of a family of unique fabrication processes developed to makeengineering prototypes in a minimum possible lead times based on a computer–aided design(CAD) model for the item1. The variety of rapid prototyping technologies arise because productdesigners would like to have a physical model of a new part or product design rather than acomputer model or line drawing2. Three-dimensional (3D) printing builds the part in a usuallayer-by-layer fashion using an ink-jet printer to eject an

In actual study, we have just evaluated the game with 22 undergraduatestudents with two targets: (1) improving user experience with application and (2) spotting Page 22.425.2bugs and troubles on application for future versions’ improvement. The data obtained fromthe use of this application by the students, as described in this article, only constitute an initialtrial version of the mobile game and, therefore, cannot provide definitive conclusions.Although the idea that these applications are really useful for enhancing and practicing thestudents’ spatial reasoning may be derived from the comments left by the

The available frequency allocations shown in FCC regulation Part 15are identified in Table 1 of the publication and entitled “Part 15 Permitted FrequencyAllocations.” Table 1 shows the frequency bands that may be used are between 38.25 MHz and3.26 GHz and the emission limits for any type of use for a transmitter. The allowable radiatedenergy is stated in the list along with the actual frequencies, emission limits and their uses.Additionally, other applications such as cordless telephones, intermittent control signals, andperiodic transmissions are not included in the Table 1 of Part 15.23.

as well as results data must be kept to be retrievable afterwards, etc.. Thispaper collects requirements from a set of use cases around RLAB. It then groups the require-ments, proposes a data model, and describes the implementation using a relational databasesystem. Furthermore some issues are discussed when extending the laboratory by further modelsand/or experiments, and the paper explains how this is taken care of by the RLAB approach.These considerations and results may help institutions to create an appropriate data managementarchitecture when establishing some own remotely accessible experimentation sites.1.

[1], we have now reachedthe era of Globalization 3(G3), in which individuals have the power to collaborate and competeglobally.Globalization 3 has led to the emergence of various new paradigms related to breakthroughinnovation that are characterized by the self-organization of individuals into loose networks ofpeers to produce goods and services in a very tangible and ongoing way [8]. Examples of suchparadigms include mass collaboration [8], collective innovation [9], collective invention [10],user innovation [11], crowd sourcing [12], open innovation [13], and community-basedinnovation [14]. While the most popular examples of community-based innovation come fromopen-source software (OSS) such as Linux, Apache, and Mozilla, many physical
, 2011 Design in Context: Where do the Engineers of 2020 Learn this Skill?Increasingly, engineers must design engineering solutions that consider the contexts in whichthey are implemented. Examples like China‟s Three Gorges Dam, the development of next-generation fusion nuclear power, and the One Laptop per Child program illustrate thecomplexities and the stakes of current and future engineering projects. The National Academyof Engineering [1, 2] argues that the “Engineer of 2020” must not only be technically capable, butalso be able to understand the contextual requirements and consequences of their work.ABET program accreditation criteria[3] promote contextual engineering practice in several of

Five years later the environmentalengineering program was incorporated, and the department renamed the School of Chemical,Biological, and Environmental Engineering (CBEE). Since this time, CBEE has worked towarda common curricula for these three “process engineering” degree programs where appropriate.Figure 1 summarizes the student distribution from the past 3 years, showing also
experiment and evolve in order to keep pacewith advances in knowledge, changes in professional practice, and shifting conditions in society.The need for responsive academic programs is particularly a concern in scientific andtechnological fields where the growth of knowledge is exponential (Rugarcia, et al.,[1]). Achemical engineering department at a big research extensive university developed andimplemented several strategies to address these issues: (1) curriculum content reform anddevelopment; (2) faculty and students assessment activities; (3) integrated assessment plans andprocesses throughout the chemical engineering curriculum. The research points out that a majorchallenge is not initiating curricular reform but institutionalizing the reform
appliances in a home environment. The wireless sensor and actuator network consists ofmultiple measurement nodes and a central server module, where the measurement nodes havetwo-way communication with the central server module. Each measurement node in the networkis connected to and reads the energy use of one AC appliance, and wirelessly reports the readingsto the central server module for processing. The server displays the readings from these nodesthrough a user visual interface in real time. This system can help users better understand theirelectricity usage patterns and adapt their behavior to reduce their energy consumption and costs.Figure 1 shows an application of this wireless energy monitoring system in a home scenario,where the

The assessmentutilizes: 1) student surveys, and 2) direct measures, i.e., student performance on related courseoutcome scores. The assessment was applied to two student groups, one that simply followedlab procedures and the other that were tasked with designing the experiments.IntroductionA successful engineer must be proficient in a variety of areas. This includes an ability to designand implement experimental methods in order to test ideas and designs. This ability is directlyaddressed in ABET Criterion 31 as “an ability to design and conduct experiments, as well as to
systems, a problem solving environment (PSE) for automated system designhas been developed. The PSE provides a virtual environment for building, testing, andvalidating designs for a process to be automated.This virtual environment allows students to design systems to automate manufacturing processes.Students may build systems to automate either a single type of process (continuous, discrete, orbatch) or a combination of processes (hybrid). The user is presented a toolbox containingequipment and building blocks of automation such as sensors and actuators. The PSE supportsstudents in design problem-solving activities such as (1) reviewing the problem, (2)understanding the process to be automated, (3) line balancing, (4) layout, (5) simulation, and
a strong programming capability. The benefits of such a laboratory course are twofold.Firstly, students learn simulation, which is widely used by engineers in the industry to verify andvalidate system designs. Secondly, these laboratory projects have been designed following theGagne‟s nine events of instruction15 which leads to an enhanced learning environment. Also,when compared to hardware based labs, such as with EMONA TIMS16, Mobile Studio17 andEttus USRP18, Simulink has the advantage of lower cost and ease of maintenance.Simulink Laboratory Projects for Communication Systems CourseSix Simulink laboratory projects are constructed to teach Simulink skills in parallel with thetheory. Table 1 enumerates topics covered in the six labs and
API libraries to access andcontrol these blocks. The processor is programmed by using the API libraries and C Language.The boards that are used in this paper are shown in Figure 1. Figure 1(a) displays the PSoC1Evaluation board while Figure 1(b) shows the wireless PSoC1 Low Power RF node. Both boardsare Cypress Semiconductor products.

The class time is split fairly evenly betweenthe project and the lecture. With much of the lecture front loaded and the project back loaded.This works well as the students have a complete background on facilities planning during thefirst part of the course and can spend many hours on the project near the end. Students are gradedon their performance on a final exam and on the project. Below (Table 1) are the learning

Therefore, thecareer opportunities for graduate engineers with a Bachelor’s degree (of only threeyears) are obviously restricted.

This is a significant change that meansengineering as a profession will have to remain socially sensitive and be aware of the ways inwhich it must adapt if it is to properly address the needs of its stakeholders. The engineers of2020 and beyond, as envisioned by the NAE‟s report, must become versed in more than thetechnical possibilities of problem solving by incorporating a deep and meaningful understandingof the social context in which their design work is situated. In going beyond, engineers shouldaspire to “expand their vision of design through a solid grounding in the humanities, socialsciences, and economics”1.The movement in

semester of 2010, the total enrollment of the INTR 225 class was 13 students, ofwhich 12 were females and 1 was male. Since this sample group was not balanced in terms ofgender and could not represent the target user population, students were instructed to find andmeasure one opposite-gender person outside the class roster. In the end, the sample group wasequalized with a total of 26 people.Due to privacy concerns, results of the anthropometric and ergonomic data gathered in this studywill not be shared in this paper.The third task of the first benchmark was to create concepts. Students used freehand sketching,digital and traditional mass studies, and other concept development techniques. In this stage, theyalso used their own data, which they had

Thecourse sequence is currently being offered for a second time.IntroductionResearch on attracting and retaining students suggests that educators should portray engineeringas a field through which one can contribute to the social good. ABET, in turn, asks that weprovide our students with “the broad education necessary to understand the impact ofengineering solutions in a global, economic, environmental, and societal context.”1 Exposingstudents to ways that technology is having an impact in low-income regions and the developingworld is one mechanism for making engineering relevant and showing its power to impact theworld positively.

Programs In a review of the development and characteristics of future faculty preparationprograms2, it is pointed out that they can provide a smooth transition between graduate schooland faculty positions. These programs evolved from TA training programs that proliferatedbetween 1960 and 1990. Establishment of the Preparing Future Faculty (PFF) program in 1993formed a base for a sustained national initiative to transform doctoral education. The PFFprogram has three core features3 of 1) addressing the full scope of faculty roles andresponsibilities, 2) students have multiple mentors and receive reflective feedback and 3) bothare addressed in the context of a cluster of institutions typically involving a doctoral degree-granting institution

The laboratory component of the course is project oriented involving severallow-cost mechatronic testbeds. The students go through the design of an embeddedcomputer system using open-architecture mechatronic testbeds and integrateddevelopment environments. Furthermore, the students experience automatic C codegeneration techniques using high level code generation tools in the Matlab/Simulinkenvironment which is further discussed in this paper.1 IntroductionEmbedded computer applications have experienced a rapid growth in the past few years1,2 .

misconceptions. Thus, the Pre-post Topic ConceptQuizzes are tools that have been used to measure effectiveness of instruction and conceptualchange. A rubric can also be used to provide a quantitative measure of conceptual gain.Another formative assessment used is the daily, class-end Points-of-Reflection assessment12.These points included: "Most Interesting Point" (with a 1-5 Likert scale), "Muddiest Point" (witha 1-5 Likert scale), and a "What Did You Learn About Your Learning?" point. The MuddiestPoint can reveal what students consider to be a "Difficult Concept" when a large fraction of theclass rates a given concept at a 4-5 average on the Likert scale. High rating averages of the "MostInteresting Point" can reveal positive student attitude on a
