Certain Integrals Arising from Ramanujan’s Notebooks

In his third notebook, Ramanujan claims that ∫ ∞ 0 cos(nx) x2 + 1 log xdx+ π 2 ∫ ∞ 0 sin(nx) x2 + 1 dx = 0. In a following cryptic line, which only became visible in a recent reproduction of Ramanujan’s notebooks, Ramanujan indicates that a similar relation exists if log x were replaced by log x in the first integral and log x were inserted in the integrand of the second integral. One of the go...

Speech reconstruction from mel frequency cepstral coefficients and pitch frequency

This paper presents a novel low complexity, frequency domain algorithm for reconstruction of speech from the melfrequency cepstral coe cients (MFCC), commonly used by speech recognition systems, and the pitch frequency values. The reconstruction technique is based on the sinusoidal speech representation. A set of sine-wave frequencies is derived using the pitch frequency and voicing decisions, ...

The Function of Pitch Range Variations in Samples of Emotional Expressions in Persian

This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

On Asymptotics of Certain Recurrences Arising

Ramanujan's Q-function and the so called \tree function" T(z) deened implicitly by the equation T(z) = ze T(z) found applications in hashing, the birthday paradox problem, random mappings, caching, memory connicts, and so forth. Recently, several novel applications of these functions to information theory problems such as linear coding and universal portfolios were brought to light. In this pap...

Variations in the Age-Incidence of Mortality from Certain Diseases

period forms a curved line above or below the mean. It is obvious that by this method any deviation from a straight line represents variation in the age-incidence of mortality. The first diagram (Fig. 1) which I will ask you to look at is based upon the deaths in London from diphtheria and croup, from the period 1859 to 1905. The first period, represented by a curved line, relates to the years ...
