This paper computes the Non-central Moments of the Truncated Normal variable, i.e. a Normal constrained to assume values in the interval with bounds that may be finite or infinite. We define two recursive expressions where one can be expressed in closed form. Another closed form is defined using the Lower Incomplete Gamma Function. Moreover, an upper bound for the absolute value of the Non-central Moments is determined. The numerical results of the expressions are compared and the different behavior for high value of the order of the moments is shown. The limitations to the use of Truncated Normal distributions with a lower negative limit regarding financial products are considered. Limitations in the application of Truncated Normal distributions also arise when considering a CRRA utility function.

Abstract This paper contains parametric and informational shape measures for various families of the generalized beta exponential distribution since it is important to determination of the distribution shape for analysing an experimental data set. A logistic parameter is used to select independent types of beta exponential distributions, that it allows to combine the distributions of different subfamilies. In this paper the use of parametric shape measures to pre-define distribution shape is discusses. In particular, the initial and standard central moments for the main types of generalized beta exponential distribution are given. In the paper it is proposes to use the entropy coefficient of unshifted distribution as an independent information measure of the shape of unshifted generalized beta exponential distributions. In order to increase the reliability of the preliminary determination of the shape of the model, expressions for the entropy coefficient of shifted families both the generalized beta exponential distributions of the first and second types, and the generalized gamma exponential distribution were obtained. For practical applied the entropy coefficients of unshifted distributions for various subfamilies of generalized beta exponential distributions can be useful.

The <span>use of the fingerprint recognition has been and remains very important in many security applications and licensing systems. Fingerprint recognition is required in many areas such as licensing access to networks, corporate computers and organizations. In this paper, the system of fingerprint recognition that can be used in several cases of fingerprint such as being rounded at an angle by a randomly inked fingerprint on paper. So, fingerprint image is tooked at a different angle in order to identify the owner of the ink fingerprint. This method involves two working levels. The first one, the fingerprint pattern's shape features are calculated based on the central moments of each image being listed on a regular basis with three states rotation. Each image is rotated at a specified angle. In the second level, the fingerprint holder entered is identified using the previously extracted shape features and compared to the three local databases content of three rotation states. When applied the method for several persons by taken their inked fingerprint on the paper, the accuracy of the system in identifying the owner of the fingerprint after rotation states were close to 83.71.</span>

AbstractIn this paper, a new $( p,q ) $ ( p , q ) -analogue of the Balázs–Szabados operators is defined. Moments up to the fourth order are calculated, and second order and fourth order central moments are estimated. Local approximation properties of the operators are examined and a Voronovskaja type theorem is given.

This book compares two mystical works central to the Christian Discalced Carmelite and the Hindu Bhakti traditions: the sixteenth-century Spanish Cántico espiritual (Spiritual Canticle), by John of the Cross, and the Sanskrit Rāsa Līlā, originated in the oral tradition. These texts are examined alongside theological commentaries: for the Cántico, the Comentarios written by John of the Cross on his own poem; for Rāsa Līlā, the foundational commentary by Srīdhara Swāmi along with commentaries by the sixteenth-century theologian Jīva Goswāmī, from the Gauḍīya Vaiṣṇava school, and other Gauḍīya theologians. The phrase “savoring God” in the title conveys the Spanish gustar a Dios (to savor God) and the Sanskrit madhura bhakti rasa (the sweet savor of divine love). While “savoring” does not mean exactly the same thing for these theologians, they use the term to define a theopoetics at work in their respective traditions. The book’s methodology transposes their notions of “savoring” to advance a comparative theopoetics grounded in the interaction of poetry and theology. The first chapter explains in detail how theopoetics is regarded considering each text and how they are compared. The comparison is then laid out across Chapters 2, 3, and 4, each of which examines one of the three central moments of the theopoetic experience of savoring that is represented in the Cántico and Rāsa Līlā: the absence and presence of God, the relationship between embodiment and savoring, and the fulfillment of the encounter between the divine and the lovers.

A new optimization method presented in this work – the Least m-Order Central Moments method, is a generalization of the Least Squares method. It allows fitting a geometric object into a set of points in such a way that the maximum shift between the object and the points after fitting is smaller than in the Least Squares method. This property can be very useful in some engineering tasks, e.g. in the realignment of a railway track or gantry rails. The theoretical properties of the proposed optimization method are analyzed. The computational problems are discussed. The appropriate computational techniques are proposed to overcome these problems. The detailed computational algorithm and formulas of iterative processes have been derived. The numerical tests are presented, in order to illustrate the operation of proposed techniques. The results have been analyzed, and the conclusions were then formulated.
