Amplitude is typically 1 milli-volt peak to peak in the presence of much larger (1000 timeslarger) external high frequency noise plus 50/60 Hz interference common mode voltages (common to allelectrode signals). We present a method to eliminate much of the noise using a pre-amplifier design withhigh common mode rejection ratio and high input impedance. We verify our results using computersimulation of the signal via the software MULTISIM 9.0.1. IntroductionThe electrocardiogram (ECG or EKG) is a graphic recording or display of the time-variant voltagesproduced by the myocardium during the cardiac cycle. [3] It is the

It willalso describe how the project was structured so that each student on the team had both an in-depthexperience within their discipline and learned how to integrate their discipline specific expertise in thelarger multidisciplinary project. Finally the paper will present the results of the students’ work andlearning outcomes.1. Introduction One of the desired outcomes of nearly all engineering programs is that the students participate ina project where their work is integrated into a larger multidisciplinary project. The multidisciplinaryproject adds more real-word constraints and considerations to the problem than a single-disciplinaryproject can offer
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
taken at the completion of the course indicated that student interest in thisproject was very high. In the interest of providing long-term retention of fundamental skills,several inductive learning techniques were employed. By maintaining student interest, we hopethat the skills they learn from this experience will stay with them throughout their engineeringcareers.IntroductionThis project, entitled the “Rainbow Sculpture: Artistic Engineering”, adapted from CliffordMatthews’ Case Studies in Engineering Design 1, is a case-based learning study that extends intohybrid problem/project based learning. “Rainbow Sculpture” borrows bits and pieces from manydifferent techniques to reach and impress upon a broad array of audiences.

medical terms, anatomic information, video format, etc., while specific ontology is a data-driven one including color, location, and region of images. The process of creating multimediaontology consists of three steps: (1)collection of raw data from WCE videos, such as video dataformat, feature values, meta-data information and anomalies, (2) classification of the raw datainto concepts including generic and specific ontology, and (3) identification of relationshipbetween two concepts such as ‘Is-A’, ‘Part-Of’, and ‘Has-A’. This WCE Ontology structure canbe used to better address the open problems by providing ‘relevant area focus’ from the formedstructure and can also be extended to other problems like detection of lesions and polyps.Keywords

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

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

It isin the city of Zarka, the second largest city in Jordan behind its capital Amman. The university isa co-ed university and it has close to one hundred engineering faculty members in manyengineering fields. The Hashemite University was the choice because one of the authors is afaculty member in it albeit the fact that he is not an engineering educator.THE SAMPLEThe sample of this investigation consists of seven engineering educators. Efforts were made tocover as many engineering fields and academic ranks as possible. Details of these educators areas follows.1. Mr

The productwas test marketed during the cold and flu season of 1990-91 and launched nationally in the fall of 1991.The launch of a new product can be used as an example of project management. Here we have a newproduct idea that had not been done before. Several organizations were needed (Manufacturing, R&D,Marketing, Finance, a contract manufacturer, Distribution, Sales, and others), all having a vested interestin the success of the project. No one organization could successfully execute the project alone. Therewas a clear timeline, a clear budget, and a clear definition of quality and customer

problem has been addressed in many different ways over the years. Backgroundenvironmental noises degrade the performance of speech-processing systems such as speech coding,speech recognition, and hearing aids. By modifying the processing according to the type of backgroundnoise, the performance can be enhanced. This requires classifying different noises. In this paper, westudied seven commonly encountered background noises: subway, highway, inside train, inside car, rain,restaurant, and airport. The acoustical properties, Auto Correlation Function (ACF), energy, and delay arecalculated. Our experimental results show significant differences between some types of noises.1.IntroductionSound environment have changed in the last four decades. The

The author found that this approach did succeed in attracting a variety ofstudents who otherwise would learn little of engineering, and in engaging them in the subject and givingthem a basic quantitative understanding of some aspects of the subject. Of course, the approach was notwithout its difficulties, including the problem of integrating very diverse material. On the whole, theauthor found that the approach worked well and recommends it for further development.The rest of this paper is in five parts: (1) An account of how and why the course was developed and itseducational goals; (2) The design of the course, including the syllabus; (3) Observations on the types ofstudents who took the course; (4) The students
some segments and used the zero crossing rate and energycalculations to separate the voiced and unvoiced parts of speech. The results suggest that zero crossingrates are low for voiced part and high for unvoiced part where as the energy is high for voiced part andlow for unvoiced part. Therefore, these methods are proved more effective in separation of voiced andunvoiced speech.1. IntroductionSpeech can be divided into numerous voiced and unvoiced regions. The classification of speech signalinto voiced, unvoiced provides a preliminary acoustic segmentation for speech processing applications,such as speech synthesis, speech enhancement, and speech recognition.“Voiced speech consists of more or less constant frequency tones of some duration
