In this analysis‚ the stator current signal transformed to the frequency domain using a FFT algorithm. The stator current signal of the motor is used to analyze and detect specific fault frequencies related to incipient faults. For stator winding fault‚ there is an associated fault frequency that may be identified in the spectrum. The stator fault has been detected by comparing the healthy power spectrum to faulty power spectrum. The power spectrum of stator current for healthy no-load condition

Teaching methods Both the grammar translation method and communicative language teaching are teaching methods for acquiring a foreign language. Whereas the grammar translation method focuses on the translation of certain grammar rules and the translation of vocabulary‚ the communicative approach aims for acquiring the skill of communication for the learner Scrivener (2011). Both methods are effective in their own way‚ although the communicative approach focuses on the actual goal of language‚ namely

The Grammar-Translation Method As “modern” languages began to enter the curriculum of European schools in the eighteenth century‚ they were taught using the same basic procedures that were used for teaching Latin. Textbooks consisted of statements of abstract grammar rules‚ lists of vocabulary‚ and sentences for translation. Speaking the foreign language was not the goal‚ and oral practice was limited to students reading aloud the sentences they had translated. These sentences were constructed to

Project – Pedal-powered phone charger CALL FOR SCIENTIFIC AND TECHNOLOGICAL RESEACH PROPOSAL FOR 2013/2014 FUNDING CYCLE PROPOSAL Students intend to do the project of building a simple pedal-powered cell phone charger to mount on my bicycle. Cell phones are small potatoes in the big picture of energy consumption‚ but the apparatus to be built could be a very practical concept for those on self-supported bike tours or those living temporarily in situations without electricity.

A UPQC has the same structure as a UPFC. It can inject current in shunt and voltage in series simultaneously in a dual control mode. Therefore it can perform both the functions of load compensation and voltage control at the same time. The UPQC must also inject unbalanced and distorted voltages and currents and hence its operating characteristics are than that of a UPFC. Furthermore their operation philosophy is different. The UPQC is also an (PQ) enhancement device. UPFC and can operate under

A Case Study for E-Democracy: Development of Electronic Voting System for STCS By: Diana Diga‚ Lovely Joy Rivero‚ Nino Patrick Bravo & Ermie De Guzman Democracy is a form of administration by citizens. Citizens have the sovereign power to administrate the country by themselves or elect their fellows to act as their representative in the administration‚ which are members of parliament. By this mean‚ one of the basic features of democracy that cuts all across broad diversity of people is the act of

On the right in Figure 27 shown the power density spectral of noise measurements at low frequencies‚ from 1 Hz to 14 Hz and used commercial resistance of 1 kΩ to compare 2 different current generators. The curves in red color correspond KEITHLEY 2400 series and the curves in black color correspond to the ADRET current generator. The KEITHLEY generator slightly lower noise than ADRET generator. However‚ theoretically the differential measure with correct polarization can suppress this kind of noise
