Development of Modified PWM Technique
ISBN: 9783659482595 / Angielski / Miękka / 2014 / 164 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. This book focuses on the torque improvement of the PM BLDC motors by minimizing the generated torque ripples. An extensive review of the applied torque ripple minimization techniques is presented. The torque ripples in BLDC motor drives usually originate from the motor design structure, as well as from the drive side in the forms of current ripples. The torque ripples from the control side appear in the forms of spikes and dips on the output torque which is inherently due to the phase current mismatch during phase current commutation. Practically, the rate of current rise and decay between...

Prospective and Design of Thermo Electric Cooling Applications
ISBN: 9783659416675 / Angielski / Miękka / 2013 / 108 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. This book presents the design of a transformer-less converter for low power applications based on CUK topology which is basically a combination of buck and boost topologies. This topology is principled on dividing the input voltage into storage devices as charging state then delivering the stored energy to the load at the discharging state. This process operated at high speed to ensure continuous conduction of load current. The converter converts input DC voltage throughout multistage voltage chopping. The transfer of energy through the capacitive elements ensures that the load current is...

Person identification using face and fingerprint authentication
ISBN: 9783659212284 / Angielski / Miękka / 2015 / 192 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. A biometric system is generally a pattern recognition system which makes a personal identification by determining the authenticity of a specific physiological or behavioral characteristic indigenous from the user. Unimodel biometric systems perform person recognition based on a single source of biometric information and are affected by problems like noisy sensor data, non-universality and lack of individuality of the chosen biometric trait, absence of an invariant representation for the biometric trait and susceptibility to circumvention. Some of these problems can be alleviated by using...

Voltage and Time Dependence of the Potential Induced Degradation(PID)
ISBN: 9783659715976 / Angielski / Miękka / 2015 / 120 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. Since the generation of solar energy is increasing and getting important worldwide .PV systems is becoming bigger with increasing the amount of serially interconnected panels. These panels are exposed to high potential relative to the ground which causing high voltage stresses (HVS). This HVS causing instability of the solar panels depending on some factors which cause an unwanted property called potential induced degradation (PID). The factors which effect on the PID are (Voltage, humidity and high temp) which generate leakage current between the solar cells and the ground. The key is to...

Wael Ghonim was a little-known, thirty-year-old Google executive in the summer of 2010 when he anonymously launched a Facebook page to protest the death of one Egyptian man at the hands of security forces. The page's following expanded quickly and moved from online protests to a nonconfrontational movement. On January 25, 2011, Tahrir Square resounded with calls for change. Yet just as the revolution began in earnest, Ghonim was captured and...

Ampacity Optimization of Unequally Loaded Power Cables - Procedure for Calculation of Optimal Current Loadings of Dissimilar Underground Cables
ISBN: 9783639063417 / Angielski / Miękka / 2008 / 120 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. This book addresses the problem of finding ampacities of underground cables. Although standard methods for solving this problem provide satisfactory results, however, these results are not always optimal and algorithms are not always convergent. This book takes these standard methods as a starting point and formulates the ampacity calculations as an optimization problem. The solution to this optimization problem gives the required ampacities, and is determined by utilizing the barrier method algorithm. This algorithm is implemented in FORTRAN-77 and used to obtain ampacity solutions for...
