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

Nonetheless, in the past decade or so, countless scholarly writings asserted the availability of[real] or virtual laboratories that mimic real laboratory experimentations. Within these virtual experiments’infrastructures, the elements of real experimentation- in comparison to conventional laboratories

By modifying the processing according to the type of backgroundnoise, the performance can be enhanced. This requires classifying different noises.

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

This paperwill discuss the author’s attempt to address this problem.Force on a spur gearWhen two spur gears are meshed shown in Fig. 1, and the left one is the driver, the contact pointmoves along a line as the gears rotate, as shown in Fig. 2. The line of action is sometimes calledthe pressure line. The force pushing the driven gear is shown in Fig. 3, and will always be alongthis line of action. The type of force is bearing (pushing) force, applying pressure to the matingtooth. From the principal of force transmissibility in statics, we know that any point along theline of action will still create the same torque about the gear. Therefore, we can use a fixedcontact point (pitch point) to simplify the
