buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Hybrid Compression Technique Using Linear Predictive Coding for Electrocardiogram Signals

Linear Predictive Coding (LPC) is used for analysis and compression of speech signals. Whereas Huffman coding is used forElectrocardiogram (ECG) signal compression. This paper presents a hybrid compression technique for ECG signal using modifiedHuffman encoding andLPC.The aim of this paper is to apply the linear prediction coding and modified Huffman coding for analysis, compression and predict...

Pole-zero analysis of speech by linear predictive coding

Linear Predictive Coding is All-Pole Resonance Modeling

Linear predictive coding (LPC) is a widely used technique in audio signal processing, especially in speech signal processing. It has found particular use in voice signal compression, allowing for very high compression rates. As widely adopted as it is, LPC is covered in many textbooks and is taught in most advanced audio signal processing courses. So why another article on LPC? Despite covering...

- 2 - Time - Varying Linear Predictive Coding of Speech Signals

For linear predictive coding (LPC) of speech, the speech waveform is modelled as the output of an all-pole filter. The waveform is divided into many short intervals (10-30 msec) during which the speech signal is assumed to be stationary. For each interval the constant coefficients of the all-pole filter are estimated by linear prediction by minimizing a squared prediction error criterion. This ...
