Estado del Arte del Flujo de Cargas Probabilistico
ISBN: 9783659050183 / Hiszpański / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. El flujo de cargas es una herramienta fundamental en el diseno y operacion de los sistemas electricos de potencia. Uno de los grandes inconvenientes del flujo de cargas convencional es su caracter determinista. En la realidad, las inyecciones en los nudos estan asociadas a incertidumbre. Esta incertidumbre se ve acentuada por la creciente penetracion de la generacion distribuida. La aproximacion determinista no ofrece, por tanto, resultados realistas en el analisis de los sistemas de potencia modernos. Con el fin de considerar tal incertidumbre, se plantea la necesidad de formular un...

A Simple approach for Speech Recognition
ISBN: 9783659227332 / Angielski / Miękka / 56 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The main objective of this work is to provide a low cost alternative for the "literate" deaf people suffering from Sensori Neural Loss and Central loss, or what we call as Permanent Deafness. Though Cochlear Implant is a solution for this problem, it requires the patient to spend Lakhs of rupees for the surgery. In a country like India, not all can afford such a huge amount of money. So, a low cost alternative would definitely help the middle class people. The proposed project describes Isolated Word Recognition of Kannada Digits. The system reads the spoken speech signal. Wavelet transform...

Denoising of Speech and ECG Signal by Using Wavelets
ISBN: 9783659231704 / Angielski / Miękka / 64 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Denoising of any type of signal is a vital part of communication and signal processing system. A signal in the communication system is the information containing part which needs to be processed, but during the process some noise is added in the signal and signal become noisy. The source of noise like noisy engine, pump etc introduces noise over telephone channel or in radio communication device. This is now necessary to denoise that signal or to remove that noise from that signal. Denoising of a signal can be done by using a low pass Butterworth filter, statistically matched wavelet filter...

A Comparative Analysis to Remove CFO in OFDM System
ISBN: 9783659235856 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The most important aspect in an OFDM is frequency and time synchronization as this form the reason for orthogonality between the subcarriers. However OFDM is susceptible to synchronization errors between transmitter and receiver local oscillator frequencies. This error is known as the carrier frequency offset (CFO) and causes ICI and also destroys the orthogonality between the subcarriers. In this literature we study the effects that CFO can cause to the SNR in an OFDM system, estimate the amount of frequency offset. Also the performance of the estimate is studied in a multipath environment....

Wireless Prepaid Billing of Digital Energy Meter
ISBN: 9783659237614 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The present system of energy billing is error prone and also time and labor consuming. Errors get introduced at every stage of energy billing like errors with electro-mechanical meters, human errors while noting down the meter reading, and errors while processing the paid bills and the due bills. There are many cases where the bill is paid and then is shown as a due amount in the next bill. There is no proper way to know the consumers maximum demand, and usage details. The major drawback of a post paid system is that there is no control of usage from the consumers side. There is a lot of...
