Figure 1, for example, shows a typical configuration of a dataacquisition system offered by AIM Sports specifically designed for motor racing.Both, the data collected and the analysis performed by the use of data acquisition systemscan be subdivided into suitable categories. This subdivision normally depends on theintended application of a data acquisition system.

Introduction The computer is ubiquitous across all engineering disciplines, and has had dramatic impact onthe nature of the engineering profession. No longer is the computer a mere tool in the engineer’stoolkit, but rather it has become a fundamental component of an engineer’s daily work. Morerecently, the rapid expansion and maturation of the internet, has resulted in the computer alsobeing adopted as a powerful collaborative medium for global engineering.The computer and the internet have also been widely adopted in education, increasing bothstudents’ learning efficiency and

There are two required laboratory classes in the curricula of mechanical engineering atLamar University: MEEN 3311 Measurements Lab and MEEN 4313 Materials Lab. These labcourses were the principal courses designed to meet the ABET EC 2000 outcome (b) related toexperimentation: an ability to design and conduct experiments as well as to analyze and interpretdata. This paper will discuss the Measurements Lab, a core junior level course for mechanicalengineering majors in the Department of Mechanical Engineering at Lamar University.

The piping includes several parallel loops, valves, flow meters, water pump,condenser/fan assembly, a 3,000 watt electric steam boiler, power meters, thermocoupleand pressure instruments and transducers. The purpose of the lab experiment is straightforward: to boil water at different pressures and record the pressure and temperature.Check the recorded temperature and pressure against the steam charts. The system alsoincludes a throttling calorimeter that the student will use to measure the enthalpy of thesteam as it exits the boiler.The

In fact, an engineering physics program, together with courses, could be viewed as auniversal donor 1. Fundamental concepts are usually covered in introductory engineeringphysics course. However, it was reported in a recent 2005 case study that some 10 to 15% ofsenior engineering students still have confusion about the difference of energy and temperature 2.The finding is consistent with an earlier 2000 report that some students identify movement ofelectricity and energy transfer as material flows, completely

Thelaboratory course brings together undergraduates from two engineering departments (electricaland mechanical) with plans to include systems and computer science students in the near future.Laboratory Hardware/Software InterfaceTo concentrate fully on the actual control design task and allow students to gain experience withindustrial control development tools, a dSPACE DS1104 DSP board6 is chosen as the maininterface between the controlled system (process) and the host computer. One of the salientfeatures of the dSPACE DS 1104 DSP-board is the ease of building real-time applications. Inorder for students to access the I/O dSPACE DS 1104 DSP-board, a software interface to theboard is required. Here, the student has two options: 1) the student can

Idealization of the real structure. This category includes all of the assumptions we intentionally make in order to model a structure. Some examples include assuming unrestrained rotation at every joint of a truss, exactly straight members, or perfectly rigid Page 11.1225.2 diaphragms. Fortunately, many of the errors induced by the idealization of the structure have a relatively small impact. The load and strength
ASSESSING TEACHING METHODS FOR A COURSE IN NUMERICAL METHODSAbstract Effectiveness of four instructional delivery modalities – 1) Traditional lecture, 2) Web-enhanced lecture, 3) Web-based self-study, and 4) Combined web-based self-study & classroomdiscussion, was investigated for a single instructional unit (Nonlinear Equations) over separateadministrations of an undergraduate course in Numerical Methods. Two assessment instruments– 1) student performance on a multiple-choice examination, and 2) a student satisfaction surveywere used to gather relevant data to compare the delivery modalities. Statistical analysis of theassessment data indicates that the second modality where web-based modules for instructionwere

To recruitcivil engineering students we emphasize that this course will give them a significant advantagefor studying structural dynamics in graduate school. This has proven to be the case, as severalcivil students have continued on to very good graduate programs in this area. Typically thecourse has 18-24 students, with a maximum of 24 based on the laboratory capacity. This pastfall there were eight civil engineering students and 14 mechanical engineering students.There are five main goals for the course:1.

Four laboratory projects were implemented: Digital Sound Effects, Touch-ToneDialing, a Voice Scrambler/Descrambler, and an exploration of Sampling and Aliasing in thecontext of the Telephone System. Each presented fundamental concepts, such as sampling andaliasing, in the context of a realistic problem. Students experienced the effects of signalprocessing manipulations aurally, visually, and in real-time, solidifying their understanding andincreasing their engagement in the material.1. IntroductionDigital signal processing (DSP) is central to modern Electrical and Computer Engineering (ECE)undergraduate curricula. The discipline of signal processing combines an extensive mathematicalbackground with
courses,business and finance aspects, as well as communication, ethics and interpersonal issues. One ofthese case studies was adapted and used in a Mechanics of Materials laboratory class as a pilotstudy on the effectiveness of the use of such a technique. In this paper the pilot study and itsresults are being discussed .IntroductionA paradigm shift is taking place in engineering and technology education. This shift is beingcaused by a number of forces.
