they arerelated and interchanged. Terms such as peak voltage, rms voltage (Vrms = 0.707*Vp), period (T)and frequency (f =1/T) are covered. At this point in the AC activity, the relationship betweenvoltage, current, resistance, and power are re-introduced with a discussion about how therelationships relate to AC circuits. The DC battery source can be replaced with an AC source inthe previous series circuits. As a result, parallel resistive circuits and all the calculations wouldbe the same except that the source is a sine wave. Additionally, sinusoidal terminology wouldhave to be used in the calculation and reporting of data. This is a key connection to the previousDC activities
addition, Volkswagen expects to be the E-mobility leader and have electric vehicles represent three percent of its product sales by 2018.15The Chevrolet Volt will have a range of 40 miles and the Ford Focus 100 miles. These rangesare consistent with a survey by the U.S. Bureau of Transportation Statistics that indicated thatmore than 75% of people commute 40 miles a day or less.1 The onboard battery charger will becapable of plugging into 110 or 220-volt outlets, and charge times will vary from about 6 to 12hours depending on the outlet type used.The electric vehicle will help provide energy storage in the emerging Smart Grid through the useof Vehicle-to-Grid (V2G) technology.

The importance of integrating both globalization and social needs intothe engineering curriculum is acknowledged by the ABET criteria6, and human need is a clearpriority of the engineering profession, as indicated in the NSPE creed*,7. However, the majorityof North American engineering students are not familiar with the contexts in which vast needsexist, such as those among the physically disabled or the estimated 4 billion people living on lessthan $2 a day (PPP)8.

Recent technological development in thin-filmphotovoltaics (PVs) is leading to new generations of consumer portable solar panels. These newsolar panels are light weight, durable, flexible, and have been reported to achieve power Page 15.349.2efficiencies of up to 10% [2]. The portable solar panels make solar power readily available formobile power needs such as outdoor enthusiast, expeditions and campers. It also providesportable solar power for the military to extend the run time of military devices including satellitecommunications, two-way radios

IntroductionClimate changes, environmental concerns, high fossil fuel price, and limited world fossil fuelsreserves are driving the increasing search for new alternative and green energy resources. Theseenvironmental concerns and the ever-increasing need for electrical power generation and steadyprogress in power deregulation have created increased interest in environmentally consciousdistributed generation. Of particular interest are alternative energy distributed generation(AEDG) systems such as wind, photovoltaic (PV), and fuel cell (FC) power generation deviceswith zero (or near zero

It is imperative for the universities to modify their curricula to meet the growingdemands of the industry.If this challenge is not responded our students and our community will be failed. More over itcould make us fall behind our peers in the other parts of the world who are racing forward incommitment, action and innovation (Darwish & Agnello 2009).Methodology:The research was conducted in two parts: 1) Studying the Implementation of LEED in the curriculum of Bachelor’s of Science in Construction Engineering Technology at IPFWThe curriculum of Bachelor’s of Science in Construction

The solar cells,batteries and fuel cells can be manufactured today but can they beat the internationalcompetition to deliver the tough commodity performance metrics? High-level roadmapsfor alternative energies have been formulated 1 but the goals remain stubbornly distant 2.That emphasizes the need to recruit and

The power conditioning unit combines the electric energy from both the solarpower plant and the wind power plant. The dc output energy of the hybrid power plant will beconverted to ac and will be synchronized with the electric power grid by the power conditioningunit. The AC output will be generated and controlled by the power conditioning unit which hasmultiple benefits of both generation of electricity with high efficiency and improvement ofelectric power quality.1.

This curve shows how the voltage generated by the solar cellvaries with the current drawn from it. The I-V curve shows how the solar cell will operate undervarying parameters such as light intensity and temperature. Ironically, the hotter the solar cellgets, the less efficient it becomes. With the solar cell being underneath the sun all day, thisbecomes an issue.Two important points on the I-V

Job and long-termcareer opportunities for recent graduates involved with the energy program are also discussed.Lastly, a discussion is included regarding what changes and additions that are planned for theenergy program at Lawrence Tech to keep the program vibrant and adapting to the ongoingknowledge and understanding needs of today’s engineering graduates.1) BackgroundIn the early spring of 2003 Lawrence Technological University (also known as Lawrence Tech)submitted a proposal to NextEnergy (a nonprofit corporation created by the State of Michiganwith the mission to support and promote alternative energy within the State of Michigan) andwas awarded one of five $100,000 grants in early summer 2003
. Page 22.105.2IntroductionFinding thermodynamic properties for various substances has traditionally been accomplished byusing thermodynamic tables. Interpolation between established values is normally requiredwhen the desired values of the properties do not exactly match the tabulated values. This can bea time-consuming process, particularly when iterative calculations requiring thermodynamicproperties are involved. A Microsoft Excel add-in that is available per Reference [1] includesthermodynamic properties for air and for flue gasses. To provide the versatility needed for awide variety of fuels and their combustion products, the thermodynamic tables from Reference[2] were written into Visual Basic Applications (VBA) in a Microsoft Excel file
, one of thefounders of pragmatism in education who believed that learning was active and that mathcould be learned through everyday activities such as cooking.[1] Building upon thisconcept, RAMP-UP has created original activities that anyone could recreate in theirhome to help teach math. For example, one of the Program’s most popular activities isthe “Marshmallows and Toothpicks Activity” where students build two-dimensional andthree-dimensional geometric shapes using marshmallows and toothpicks.Following a pragmatist approach, it is believed that active learning is a fun and feasibleteaching style that replaces words with activities as the means of communicating newconcepts. RAMP-UP creates opportunities for active learning through many out
configurations. PV modules,commonly called panels, are a collection of PV cells that are connected in series and/or parallelcombination and bound together on a common frame. A row of modules connected in series iscalled a series string or simply, a string. The combiner box contains several protection devicessuch as circuit breakers and combines the series strings into a single output. The inverterconverts the DC power from the array into standard AC electricity.Solar Radiation and Local ClimateSolar irradiation is the total amount of solar energy collected on an area over time. Solarirradiation is typically expressed in kWh/m2. At most locations on Earth, solar irradiation willpeak around 1 kW/m2 every day around solar noon. Insolation is the solar

This program began recently, in the fall of 2010. In order to provide an initial evaluation of a sample of courses in the program a survey was administered to students currently enrolled in undergraduate and graduate courses that are part of the program. One part of the survey focused on the impact of the courses on motivation and engagement, and the other consisted of Felder’s Inventory of Learning Styles (ILS) [1]. Results indicated that motivation and engagement, in this context, could be conceived of as
RequirementsThe battery cycler is intended to work with individual cells of voltage ranging from 1.0 to 4.2volts. This range covers popular battery types such as NiMH and Li-Ion. It is intended to allowfor high current charge and discharge of cells 2- 5 amp-hours. Ideally, the cycler can beexpanded to test from 1 to 100 cells. The cycler can also heat the cells to an elevated temperatureand keep that temperature regulated with less than 1 degree C error.Commercial Equipment OptionsSeveral life cycle testing commercial solutions are available and offer a good set of features fordata acquisition, selection of charge/discharge profiles, and high or low current dischargecapability. However, the cost of these systems is high. Unfortunately, these systems can
traditional non-renewable energy sources are dwindling and concerns over environmentalpollution are rising everyday due to increased use of fossil fuels, the focus of the automotive andboat industry have shifted to production of hybrid electric vehicles that are more energy efficientand have less green house gas emission rates. In particular, there is an educational and industrialincrease in hybrid and electric boat projects [1-5]. The first electric boat was developed by Moritzvon Jacobi in 1839 in St Petersburg, Russia, a 24-foot boat which carried 14 passengers at3 mph. However, it took more than 30 years of battery and motor development before this craftbegan to be deployed in any numbers. In 1886, an electric boat crossed the English Channel

Moreover,increasing numbers of manufacturers are beginning to evaluate their products and even theirproduct packaging for sustainability, whether to meet mandatory retail initiatives or to reap someof the rewards associated with greater environmental stewardship. This shift in product designmeans that engineering education needs to produce engineers that can provide technologicalinnovation while protecting the environment. These demands also mean that universities acrossthe nation need to build bridges between undergraduate engineering education and sustainabilityengineering in both research and industry.1 This paper describes an approach to includesustainability engineering within an existing engineering program through 1) curriculumdevelopment

circular swept area of 1 m diameter or less. The rotors were designedusing the traditional blade-element-momentum method. The performance of the blade waspredicted and then the blades and hub were constructed and tested at the given windspeedfor several loads. These tests provided data which allowed for a comparison between thepredicted turbine design performance to its actual performance. Previous manufacturingtechniques which formed each blade by removing material from a single rough block ofmaterial proved unsatisfactory since they were either too costly, required large amounts ofmachining time, or were too inaccurate due to hand construction. These problems led tothe development a new technique using recyclable molds to quickly and accurately

Also about 12% of the total energy generated in the United States was from renewablesources in 2012. New renewables (small hydro, modern biomass, solar, wind, geothermal)account for another 3% share and are rapidly increasing 1. In its new monthly forecast, EIA,reports that solar generation in the electric power sector is expected to grow even more
Energy SystemsIntroduction The low percentages of students being retained in engineering majors have been welldocumented [1]. Without increasing the numbers in this subset, it is difficult to impact thenumbers of new graduates entering the workforce and pursuing higher degrees. The problemwith the general image of engineering that is known to contribute to low enrollments is the lackof understanding of how engineering can be used to improve society. One way to this image is to engage students in hands-on experiments. The students’ interest inscience and engineering can be increased if they are exposed to more hands-on researchexperiences rather than what is traditionally offered in undergraduate curricula. Those personalstudent experiences
