It operates on single phase, DC or brushless DCsupply. The universal power cell has three balanced Hall effect devices, each with a fluxconcentrator. Each phase wire that carries current passes through an individual hole. Themagnetic flux around the wire is proportional to the current passing through the cable. A voltagesample for each phase is also provided. The Hall effect

What is the motivating force for the university, the facultymember and the company to enter into a faculty internship? University faculties have beenfacing the challenge of maintaining currency in knowledge and skills for decades. This has beenparticularly difficult for faculty in technical fields.

recognizing the phonemes in a waveform and understanding parameterization, thestudent needs to understand how to apply a decision using a threshold. By further reducing theshort parameter vector to a scalar, the relational operators learned in the MATLAB tutorial (whichoperate on scalars but not on vectors) may be applied. In this way, MATLAB scripts may be writ-ten to distinguish between speech waveforms representing two words. The threshold is the valueof the scalar that marks the point of separation between the two words. If the value of the scalaris greater than the threshold, the word is ‘A’; if it is less, the word is ‘B’.Three operations that reduce a parameter vector to a scalar are introduced: the MATLAB functionsSUM, MEAN and MAX.

Among their findings was the need for large buttons, less confusing error messages, and more visible activity on the screen during long down-loads. One issue with error messages was the need to reassure children that they had not done anything wrong, if for example, a URL was not found.

Effect of Drag ForceWhen there is drag on the pumpkin there is no simple equation to calculate the range since dragforce is not constant. Assuming that the drag coefficient is constant, the drag force is a function ofvelocity only. Even with a constant drag coefficient, the equations of projectile motion need to benumerically integrated to find the range.Drag force is given byFD=CD.rho.AP.Vo2/2whereCD= Drag coefficientrho= density of airAP=projected area of pumpkinInitially and towards the end of the motion drag force is large since pumpkin is moving at

We hope that we can give the students an appreciation of why this is wrong.The emphasis of Interactive Dynamics is not, and should not be, on writing since it is not a writ-ing-intensive course. Thus, the emphasis placed on the report style is minor when compared tothe emphasis placed on the dynamics content of the activity problems.
