This paper has four interrelated themes: 1 express Laplace and Mellin transforms of sums of positive random variables in terms of the Mellin transform of the summands; 2 show the equivalence of the two Barnes' lemmas with known properties of gamma distributions; 3 establish properties of the sum of two reciprocal gamma variables, and related results; 4 study the G distributions whose Mellin transforms are ratios of products of gamma functions.

Gamma distributions occur frequently in models used in engineering such as time to failure of equipment and load levels for telecommunication services , meteorology rainfall , and business insurance claims and loan defaults for which the variables are always positive and the results are skewed unbalanced. The gamma function, a generalization of the factorial function to nonintegral values, was introduced by Swiss mathematician Leonhard Euler in the 18th century.

The double factorial of a positive integer is a generalization of the usual factorial defined by. Note that , by definition Arfken , p. The origin of the notation appears not to not be widely known and is not mentioned in Cajori For , 1, 2, OEIS A The numbers of decimal digits in for , 1, The double factorial is implemented in the Wolfram Language as n!!

The double factorial is a special case of the multifactorial. The double factorial can be expressed in terms of the gamma function by. Arfken , p. There are many identities relating double factorials to factorials. For , 1, For odd ,. For even ,. Therefore, for any ,. OEIS A , where is a lower incomplete gamma function. This sum is a special case of the reciprocal multifactorial constant. Hardy , p. Whipple gives a generalization of this sum Hardy , pp.

The purpose of this paper is to determine whether gamma-band activity detection is improved when a filter, based on empirical mode decomposition EMD , is added to the pre-processing block of single-channel electroencephalography EEG signals. EEGs from 25 control subjects were registered in basal and motor activity hand movements using only one EEG channel. Over the basic signal, IMF signals are computed. Gamma-band activity is computed using power spectrum density in the 30—60 Hz range. Event-related synchronization ERS was defined as the ratio of motor and basal activity.

Интересно, что они еще придумают. Телефон на столе громко зазвонил. Сеньор Ролдан поднял трубку с обычной для него самоуверенностью. - Buenas noches, - произнес мужской голос на беглом испанском; звонивший выговаривал слова чуточку в нос, словно был немного простужен.  - Это гостиница.

 Они повсюду! - крикнула Соши. - Присоединяются зарубежные налетчики! - крикнул один из техников.  - Уже обо всем пронюхали. Сьюзан отвернулась от экрана ВР к боковому монитору.
