The practice of this process seems to improve the completion of the activities and the outputs. This processes has never been analyzed or measured. I am interested and excited to learn where improvements might aid productivity and quality. This process includes the activities needed to attend‚ complete‚ and earn a good grade in a class at

Dehghan Dehnavi‚ Student Member‚ IEEE‚ Mustafa Mohamadian‚ Member‚ IEEE‚ Ali Yazdian‚ Member‚ IEEE‚ and Farhad Ashrafzadeh‚ Senior Member‚ IEEE Abstract—Recently‚ nine-switch inverter and nine-switch-zsource inverter have been proposed as dual output inverters. In this paper‚ the space vector modulation (SVM) of nine-switch inverter and nine-switch-z-source inverter is proposed. The proposed method increases the sum of modulation indices up to 15% in contrast with the conventional‚ scheme in

usually adopts either DEA or SFA method‚ but not both of them. Therefore‚ this paper is aimed to measure the operating efficiencies of 27 international container ports from 1999 to 2002 by applying both SFA and DEA models with three inputs and single output. The result shows that the total average of operating efficiency scores are SFATR(0.8217) ＞ SFACD(0.7979)＞DEABCC(0.7075)＞DEACCR(0.6150)‚ and Hong Kong port demonstrates the best performance in each model. Also‚ three hypotheses for port performance

express Vis. Theory: The dynamics of a linear system can be represented through linear derivative equations. The representative equation of a first order system is as follows: Here τ is the time constant‚ x(t) is the input and y(t) is the output. The discrete form of the equation is as follows‚ with t=n: This is the iteration used in the simulation of the dynamic response of the first order system. The typical representation of the second order system is as follows: The

ADC 3-bits Flash DURRMANN Antoine – GEAMBLU Clément 1 I- Introduction We have decided to design an one-step Flash converter. As shown in the schematic below‚ in this type of ADC the input signal is compared to the 2n nodes of resistors. At the output of the comparators‚ the sampled input value can be read in thermometer-code. At the beginning of this project‚ we were novice in circuit

signal. Using the oscilloscope‚ the mean value was found to be -37.6 mV‚ the RMS Voltage was 292 mV‚ the frequency was 1 kHz and the Peak to Peak voltage was 1.01 V. The values observed‚ differed from what was expected as a result of the inaccuracy to output perfect values. The triangular wave was then given a non-zero DC Offset. The latter change displaced the triangular signal vertically by keeping its initial frequency and Peak to Peak values. Another goal of Part 1 was to determine how AC and DC coupling

CHAPTER 4 HARDWARE DESCRIPTION 4.0 Arduino: The Arduino Uno is a microcontroller based on the ATmega328. It has 14 digital input/output pins in which 6 can be used as PWM‚ 6 analog inputs‚ a 16 MHz ceramic resonator‚ a USB port‚ a power jack‚ an ICSP header‚ and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.[11] The Uno differs from all preceding boards in
