Upon successful completion of this course, students will be able to: * Create lumped parameter models (expressed as ODEs) of simple dynamic systems in the electrical and mechanical energy domains * Make quantitative estimates of model parameters from experimental measurements * Obtain the time-domain response of linear systems to initial conditions and/or common forcing functions (specifically; impulse, step and ramp input) by both analytical and computational methods * Obtain the frequency-domain response of linear systems to sinusoidal inputs * Compensate the transient response of dynamic systems using feedback techniques * Design, implement and test an active control system to achieve a desired performance measureMastery of these topics will be assessed via homework, quizzes/exams, and lab assignments.

Choice of material has implications throughout the life-cycle of a product, influencing many aspects of economic and environmental performance. This course will provide a survey of methods for evaluating those implications. Lectures will cover topics in material choice concepts, fundamentals of engineering economics, manufacturing economics modeling methods, and life-cycle environmental evaluation.

The aim of this paper is to illustrate the effect of initial stresses on the propagation of plane waves in a general anisotropic elastic medium. Therefore, we present an analytical treatment supported by extensive numerical illustrations of the bulk acoustic wave propagation in Aluminium Nitride (AlN) as piezoelectric hexagonal elastic material. The characteristic equation which is Christoffel's equation is solved. The velocities of wave propagation in this material under the influence of initial stresses are calculated and compared without that influence and the results are presented graphically. This study is useful in signal processing, sound system and wireless communication in addition to improvement of SAW wave devices and military defence equipment.

Broadcasting is used in on-demand routing
protocols to discover routes in Mobile Ad-hoc Networks
(MANETs). On-demand routing protocols, such as AODV (Adhoc
On-demand Distance Vector) routing, commonly employ
pure flooding based broadcasting. However, pure flooding
generates excessively redundant routing traffic that may lead to
broadcast storm problem (BSP) and deteriorate the performance
of MANETs significantly. Probabilistic broadcasting schemes
were proposed in the literature to address BSP. However, these
schemes do not consider thermal noise and interference which
exist in real life MANETs, and therefore, do not perform well in
real life MANETs. This paper presents a novel Channel Adaptive
Probabilistic Broadcast (CAPB) scheme to disseminate RREQ
packets efficiently. The proposed CAPB scheme determines the
probability of rebroadcasting RREQ packets on the fly according
to the current SINR (Signal to Interference plus Noise Ratio) and
node density in the neighborhood. The proposed scheme and two
related state of the art (SoA) schemes from the literature ( [1] and
[2]) are implemented in the standard AODV routing protocol to
replace the pure flooding based broadcast. Simulation results
show that the proposed scheme outperforms the standard AODV
and the two competitors in terms of routing overhead,
throughput and end-to-end delay significantly

This lesson introduces students to the fundamental concepts of electricity. This is accomplished by addressing questions such as "How is electricity generated," and "How is it used in every-day life?" The lesson also includes illustrative examples of circuit diagrams to help explain how electricity flows.

Building on concepts taught in the associated lesson, students learn about bioelectricity, electrical circuits and biology as they use deductive and analytical thinking skills in connection with an engineering education. Students interact with a rudimentary electrocardiograph circuit (made by the teacher) and examine the simplicity of the device. They get to see their own cardiac signals and test the device themselves. During the second part of the activity, a series of worksheets, students examine different EKG print-outs and look for irregularities, as is done for heart disease detection.

First published in 1968 by John Wiley and Sons, Inc., Electromechanical Dynamics discusses the interaction of electromagnetic fields with media in motion. The subject combines classical mechanics and electromagnetic theory and provides opportunities to develop physical intuition. The book uses examples that emphasize the connections between physical reality and analytical models. Types of electromechanical interactions covered include rotating machinery, plasma dynamics, the electromechanics of biological systems, and magnetoelasticity. An accompanying solutions manual for the problems in the text is provided.

" This is an advanced course on modeling, design, integration and best practices for use of machine elements such as bearings, springs, gears, cams and mechanisms. Modeling and analysis of these elements is based upon extensive application of physics, mathematics and core mechanical engineering principles (solid mechanics, fluid mechanics, manufacturing, estimation, computer simulation, etc.). These principles are reinforced via (1) hands-on laboratory experiences wherein students conduct experiments and disassemble machines and (2) a substantial design project wherein students model, design, fabricate and characterize a mechanical system that is relevant to a real world application. Students master the materials via problems sets that are directly related to, and coordinated with, the deliverables of their project. Student assessment is based upon mastery of the course materials and the student's ability to synthesize, model and fabricate a mechanical device subject to engineering constraints (e.g. cost and time/schedule)."
