INTRODUCTIONECALC v2.0 is a menu-driven windows-based1 interactive program for the solution ofknown electronic circuits. With ECALC you can solve the basic types of transistorcircuits found in a typical analog electronics course. The main type of calculations thatECALC can perform are: • DC Bias calculations, and • Small-signal amplifiers calculationsfor electronic circuits with one transistor (one stage). In its present version ECALC is capable of analyzing circuits composed of bipolarjunction transistors (BJT) and some members of the FET family of transistors, namelyjunction

In another paper, we identified principles to guide thosepracticing ecological engineering that reflect our own thinking as well as ideas from others whohave written on engineering and ecological design (Bergen et al., 1997b). The five basic designprinciples we propose are: 1. Design consistent with ecological principles 2. Design for site-specific context 3. Maintain the independence of design functional requirements 4. Design for efficiency in energy and information 5.

The part time students are adult students who hold fulltime jobs. Hence, they are familiar with the workplace and know why they are going to schooland what they hope the degree will do for their career. We wanted to learn how similar theirresponses were, compared to the alumni responses and if current evening students could providea proxy for our alumni in future surveys. A total of 133 responses were received from EETstudents, including 74 alumni and 47 current part time students. RESULTSTo characterize the

L is assumed very large, so that output current can be considered having no ripple at all. The diodes used are ideal diodes with zero switching delay. Hence, the shape of the output current is rectangular. But, this causes electromagnetic interference. UF of the transformer is only 74%, as each phase conducts 1/3 of the time in every cycle.Because it points out clearly the main points of important areas of the subject, this workbook waswell received by the

INTRODUCTIONA recently received e-mail message contained a quote attributed to Albert Einstein:"In theory, there is no difference between theory and practice; in practice there is."This quote from Einstein is wrong on several counts, and therefore needs a more extensivediscussion. It leads to misinterpretations of both theory and practice, and of the relationshipsbetween them. It assumes that there is a conflict situation, a dichotomy. The falseness of theimpression of dichotomy can be shown by several other quotations from eminent people:"Theory and Practice are not antagonistic, as is so often tacitly assumed. Theory is notnecessarily unpractical, nor Practice unscientific, although both of these

As an example, if vibrato (a slight periodic (a few hertz) variationof the frequency of a sound) is desired, the sinusoidal output of a low-frequency oscillator(LFO) would be connected to the frequency control input of a voltage-controlled oscillator(VCO). The output of the VCO would then vary in frequency sinusoidally at the rate setby the LFO.Although there are many of types of modules that can be constructed to generate andmodify sounds (or rather audio frequency electrical signals) there are only a few which areused to implement most sounds. Out of this group, some are beyond the scope of anintroductory circuits course, so the problem was to determine a subset of modules whichwould be sufficient to

Whenever energy efficiency and conservation curb the use offossil fuels, a reduction in CO2 emissions will follow as well as other pollutants contributing toacid rain and urban smog. Energy conservation must interface with a facility’s pollution controlprogram along with the energy savings steps.

We should let the student build his/her own psychical model wheneverpossible.Even abstract problems in descriptive geometry such as auxiliary view planes and the projectionof points, lines and planes on these view planes are a big problem for a student to visualize. Inmy courses, students were allowed to manipulate their own drawings and were encouraged tofold back the sheet of paper along the fold line to see that “mysterious” auxiliary view plane.Once the student had done it, it was no longer a problem for him or her to understand andconceive what we were speaking

the relative simplicity of the Anglo-Saxon model in engineering education(B.S./3-4 years, M.S./1-2 years, Ph.D./3-4 years), the French system may be characterized by theextreme diversity of its components, namely: * The varying size of its institutions * The eclectic nature of the organizations which run and fund the institutions * The organization of the academic curricula and the subjects taught. Another important difference between the Anglo-Saxon and French models concerns thesocial status of engineers. In France, engineers tend to occupy the upper echelons of managementposts, competing with other specialists (such as economists and business school graduates) forthe highest positions in government and industry
