A treatment of the mathematical properties is provided for the Lindley distribution. The properties studied include: moments, cumulants, characteristic function, failure rate function, mean residual life function, mean deviations, Lorenz curve, stochastic ordering, entropies, asymptotic distribution of the extreme order statistics, distributions of sums, products and ratios, maximum likelihood estimation and simulation schemes. An application to waiting time data at discrete mathematics and its application pdf bank is described.

The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. To calculate the five year Impact Factor, citations are counted in 2016 to the previous five years and divided by the source items published in the previous five years.
SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field. SJR is a prestige metric based on the idea that not all citations are the same. Publishing your article with us has many benefits, such as having access to a personal dashboard: citation and usage data on your publications in one place. This free service is available to anyone who has published and whose publication is in Scopus.
Contributions presented to the journal can be research papers, short notes, surveys, and possibly research problems. The “Communications” section will be devoted to the fastest possible publication of recent research results that are checked and recommended for publication by a member of the Editorial Board. The journal will also publish a limited number of book announcements as well as proceedings of conferences. These proceedings will be fully refereed and adhere to the normal standards of the journal. Potential authors are advised to view the journal and the open calls-for-papers of special issues before submitting their manuscripts. Only high-quality, original work that is within the scope of the journal or the targeted special issue will be considered.
We also provide many author benefits, such as free PDFs, a liberal copyright policy, special discounts on Elsevier publications and much more. All published items, including research articles, have unrestricted access and will remain permanently free to read and download 48 months after publication. The most downloaded articles from Discrete Applied Mathematics in the last 90 days. The latest Open Access articles published in Discrete Applied Mathematics. Since 1st September 2013, we have made over 200,000 archived mathematics articles freely available to the mathematics community.
Release of STIX Fonts Version 2. All articles published after 48 months have unrestricted access and will remain permanently free to read and download. Special issues published in Discrete Applied Mathematics. This article is about the study of topics such as quantity and structure. When mathematical structures are good models of real phenomena, then mathematical reasoning can provide insight or predictions about nature.
The research required to solve mathematical problems can take years or even centuries of sustained inquiry. The universe cannot be read until we have learned the language and become familiar with the characters in which it is written. It is written in mathematical language, and the letters are triangles, circles and other geometrical figures, without which means it is humanly impossible to comprehend a single word. Without these, one is wandering about in a dark labyrinth.
David Hilbert said of mathematics: “We are not speaking here of arbitrariness in any sense. Mathematics is not like a game whose tasks are determined by arbitrarily stipulated rules. Rather, it is a conceptual system possessing internal necessity that can only be so and by no means otherwise. There is no clear line separating pure and applied mathematics, and practical applications for what began as pure mathematics are often discovered.
Mathematics has since been greatly extended, and there has been a fruitful interaction between mathematics and science, to the benefit of both. Mathematical discoveries continue to be made today. 9 million, and more than 75 thousand items are added to the database each year. The word for “mathematics” came to have the narrower and more technical meaning “mathematical study” even in Classical times. This has resulted in several mistranslations. Some of these definitions emphasize the deductive character of much of mathematics, some emphasize its abstractness, some emphasize certain topics within mathematics.
