Accelerating Engagement of First-Year Students in Academics: Use of Ideas from Quality Literature David A Gray Messiah College Grantham, Pennsylvania Abstract: This paper discusses three ideas that stem from concepts in the literature of Quality that combine to promote a more rapid transition of first year engineering students from the high school environment to the academic environment of college. These three ideas are: 1) The student is the primary employee in the academic process, 2) Grade distribution interpreted in the
analogsignal. Digital control is the simpler of the two control methods since only an on/offsignal need to be received by the device. For a solenoid valve a 5 volt signal might turnthe valve on while a zero volt signal would turn the valve off. An electrical heater isanother example of a device that can work with either digital or analog control. Theheater can either be on or off, digital control, or we can vary the current to the heater,proportional control. To send these signal we simply need an electrical switch. A simpleelectrical switch available commercially is called solid state relays. Other electricalswitches are available.The students also master the following skill list:1.

applications of feedback control techniques.1. IntroductionThe ball-on-beam balance system is a classic example of feedback control systems. The problem is tomaintain the position of a ball at the center of a beam on which the ball rolls along freely. The ball willreturn to the center position after it has been displaced from this location. This system is an effectiveeducational tool for teaching feedback control principles. Some of these systems are commerciallyavailable[1,2,3].The set-up of our ball-on-beam system is shown in Fig. 1. The beam is a 55” long, grooved aluminumbeam that a regular rubber ball can roll along freely. The beam is mounted at the center to a servo motor,which can tilt the beam in clockwise and counter-clockwise directions

IntroductionThe next generation of the IEEE802.16/WiMAX will be the most important component of the wirelesssystem. The standard version of IEEE 802.16/WiMAX employed advanced radio transmission technologyfor example OFDM (orthogonal frequency division multiplexing), adaptive modulation and coding, andEFC (adaptive forward error correction). The main purpose of using IEEE802.16/WiMAX is to providewell defined quality-of-service broadband wireless capabilities.IEEE 802.16/WiMAX technology needs a high rate transmission (about tens of Mbps), and strict quality-of-service for both indoor

In this paper, we present apreemptive goal programming model for the School of Engineering at the University of Bridgeport. Dataand case studies are provided along with a list of objectives for the Engineering School.Keywords: School of Engineering, Enrollment, Sustainability, Quality of Education, Preemptive GoalProgramming, Multiple Criteria Optimization.1. IntroductionToday, ever-decreasing budgets and dynamic variations in the number of both faculty and student bodiesare two major challenges that most U.S. universities deal with. In addition to the effort to solve theseproblems, every higher education institution also concentrates on ensuring
globalization and sustainable design anddevelopment. The course format consisted of three, 50-minute class meetings per week for the13-week semester (39 total class meetings). Class meeting times were used for lectures,workshops, and term project presentations. The first offering of the course was to a class of 16engineering seniors. COURSE TOPICS Course topics and the number of lectures, assignments, workshops, and in-class exercisesdedicated to them are presented in Table 1. Most topics involved traditional, stand-uppresentations. Often these presentations included in-class exercises that forced students toconsider and respond to the subject matter instantaneously. At other times, take-home mini-assignments were used to reinforce lecture

Typical lab modules developedand taught in the Mechanical and Industrial Engineering Programs include: 1. The CAD/CAM module:involves designing a spline with 6, 8, or 12 grooves using AutoCAD or Pro-Engineer, making the splineon a CNC machining center using the rotary axis (XZ-plane), measuring certain dimensions of the partmade, and making an error analysis; 2. The robot module: involves the use of a programmable five-axisrobot (CRS A255) for a Kool-Aid mixing application consisting of designing and building a fixture tohold a cup for Kool-Aid mix, cup for sugar, bottle of water, a
investigation of cognitive learning within the engineering profession is rather new, it hasbeen accepted by other fields of education with the most notable being the study of medicine. Untilrecently, the four-year medical school experience centered around lecture and laboratory work, somewhatsimilar to engineering education, with clinical work occurring primarily during the fourth year. Todaymany medical schools include clinical experience early in the medical school experience because studentshave demonstrated a better grasp of material when they are concurrently studying in “traditional” coursesand experience greater cognitive learning through the combination of clinical (problem-based learning)and lecture activities.1 A similar inclusion of

Russian students possess great background inmathematics whereas students from Latin America are very good with traditional electrical engineeringtopics such as power engineering. Many of them, e.g., the students from different Indian Institute ofTechnologies (IITs) or Tsinghua University, come with outstanding undergraduate training. However, theM.S. student population in teaching oriented schools seems to show some common characteristics. Wedescribe below these observations and anecdotal reasons that perhaps explain the observations. Note that,these observations should not be construed as negative comments in any way, but merely as whatthe author has experienced. 1.

Groover [1] defines a PLC as: “Amicrocomputer-based controller that uses stored instructions in programmable memory to implementlogic, sequencing, timing, counting, and arithmetic functions, using digital and analog input/output (I/O)modules, for controlling machines and processes.” Although PLC’s are used in the process industries(e.g., processing mined materials and oil refineries), they are more commonly found in discretemanufacturing industries, such as in machine control, transfer lines, and material handling equipment.First conceived in 1968 by Richard Morley, the PLC was originally developed as a device to overcomethe inflexibility and high cost of hard-wired controllers made of
wealthier citizens reside adjacent to others living in extreme poverty. Many of thepoor neighborhoods originated from the occupation of land without permission (i.e. squatters). Theseland invaders or “Invasores” as they are called in the local community staked their claims by buildingsmall shacks on parcels of land. These dilapidated houses were built quite literally using any materialsthat the people could get their hands on. Over time these communities grew as the walls of one housebecame the walls of the next. One of these neighborhoods, called Luz Consuelo, is shown in the satellitephotograph in Figure 1. Notable is the poor condition of the houses as compared to the wealthiersurrounding neighborhoods. Figure 2 shows some of the materials that

This change was made for all eight engineering programs such that all engineeringstudents would experience a common curriculum during the first year. Many benefits have resulted fromthis change over the past decade including the following highlights: • Retention of engineering students from the freshman year to the sophomore year increased from ~60% to ~72% (see figure

Nonetheless, in the past decade or so, countless scholarly writings asserted the availability of[real] or virtual laboratories that mimic real laboratory experimentations. Within these virtual experiments’infrastructures, the elements of real experimentation- in comparison to conventional laboratories
Early and Continuous Exposure to Engineering as a Profession: Career Imprinting in Grades PK-12 Hudson V. Jackson, PhD, P.E and Evelyn A. Ellis, Ed.D United States Coast Guard Academy, New London, Connecticut, U.S.A.AbstractIn recent years, there has been much discussion about declining interest in engineering programsthroughout U.S. colleges and universities. Several possible causes for the decline have been identified andare fodder for debate: (1) PK-12 educational systems are not adequately preparing students tocomprehend the connections among science, technology, engineering, and mathematics (STEM) andfuture career opportunities and (2) College engineering curricula need to be more
horrible accidents whenhumans contact high voltage. In this article we cite 3 cases of high voltage accidents.Each accident teaches something different about electricity and electric safety.Let us first begin with some clarifications. By formal definition, high voltage is definedas any voltage above 600 volts. Below 600 volts, one should consult the NEC (NationalElectric Code) for the rules of electrical installation and safety [1]. Above 600 volts, thebetter safety code is written by OSHA [2]. This should not in any way diminish thedanger of low voltage circuits. People die in their homes every day from electrocutioncaused by 120 and 220 volt sources. Furthermore, we have personal experience ofvisiting factories and other sites where electricity
materials that leads to a composite that exhibit superior properties than any one ingredientalone.While composites can be made out of a number of components, most composites are made of just two.One of them is known as matrix phase which is continuous and surrounds the other one known asdispersed phase. Mechanical properties of composites are a function of those of the ingredients, as wellas their relative fraction amounts, and how the dispersed phase is distributed. The distribution ischaracterized by type/shape of the dispersed phase particles, size of the particles, as well orientation anddistribution.Distribution of fibers in fiber-reinforced composites is varied as per the application or load to be carried.These types are (1) continuous fiber
insufficient figures to illustrate these rules. This paperwill discuss the author’s attempt to address this problem.Force on a spur gearWhen two spur gears are meshed shown in Fig. 1, and the left one is the driver, the contact pointmoves along a line as the gears rotate, as shown in Fig. 2. The line of action is sometimes calledthe pressure line. The force pushing the driven gear is shown in Fig. 3, and will always be alongthis line of action. The type of force is bearing (pushing) force, applying pressure to the matingtooth. From the principal of force transmissibility in statics, we know that any point along theline of action will still create the same torque about the gear. Therefore, we can use a fixedcontact point (pitch point) to simplify the
experimentally after it was shown geometrically, theyoungsters cut out symmetrical geometric shapes and hung them with a plumb-line from two points ondifferent lines of symmetry confirming that their intersection was the center of mass as shown in Figure-1. Through simple qualitative discussion and demonstration the students were introduced to the fact thatfor every object, regardless of its shape and size, when freely suspended from any point on the shape, aplumb line will always pass through the center of mass. Using two points not on the same line of “masssymmetry” will result in an intersection which is the mass center of the object as illustrated in Figure-2.During this experiment the principal of gravity and how it works was explained and

(See Felder, 2004.) A recent, andwidely publicized, illustration of the trend was the creation in 1997 of the Olin College ofEngineering. The Olin Foundation made a $300 million investment to establish a new college ofengineering that would integrate project work in all four years of the new curriculum.(Somerville, et al, 2005).For almost 20 years, there has been significant investment by the National Science Foundationintended to increase
content means making tough choices about what to remove in order tomake room. This paper proposes a viable method for weaving a green environmentality into a standardundergraduate reinforced concrete design course without sacrificing course content. The United States Green Building Council has established an industry standard in Green BuildingRating Systems with their Leadership in Energy and Environmental Design (LEED) certification. TheLEED certification process involves earning credits for environmentally friendly construction processesand materials and the use of efficient building systems. The certification has several tiers (gold, silver,etc.) for different levels credit.1 One way LEED credit can be earned is through use of recycled
1 Inclusion of RFID in a BSEE CurriculumJohn Adams and Charles Kochakian, Merrimack College Department of ElectricalEngineeringAbstractThis paper discusses the evolution of a course in RFID which is now a required part of thecurriculum in Merrimack College’s BSEE program. In 2004 the department identified RFID as animportant emerging technology that would be timely to introduce at the undergraduate level.Initially, the department sponsored two seminar series with sessions taught by industryprofessionals, followed in 2007 with a full course in RFID. Advantages of RFID as a requiredcourse include using it to introduce
