The traffic is modeled as a stochastic process representing the demand that users of a communications network impose on the resources of the network. Originally it was considered that the times between arrivals of the demands of the users were independent of each other, as well as the same quantity of the demand (times between calls and duration of the calls, times between arrival of packages and length of the packages, times between requests for connections and length of sessions, etc.). Later, it was necessary to include the effect of the existing correlation between these variables, for which more elaborate models were developed in which the correlation declined exponentially with time. However, it has recently been shown that in modern communications networks, the correlation between these variables does not decay as rapidly and can persist across many time scales. This phenomenon, which significantly affects the performance of communications networks, can be adequately represented by fractal or autosimilar and multifractal traffic models. This article presents the basal concepts that are involved in the study of these models, in order to facilitate the reader introduction to the specialized literature on the subject.

Climate change and its impact on water resources is the problem of the times. Therefore, this study is concerned with the subject of climate change and its impact on the water ration of the grape harvest in Diyala Governorate. The study was based on the data of the Khanaqin climate station for the period 1973-2017, (1986-2017) due to lack of data at governorate level. The general trend of the elements of the climate and its effect on the water formula was extracted. The equation of change was extracted for the duration of the study. The statistical analysis was also used between the elements of the climate (actual brightness, normal temperature, micro and maximum degrees Celsius, wind speed m / s, relative humidity% The results of the statistical analysis confirm that the water ration for the study area is based mainly on the X7 evaporation / netting variable, which is affected by a set of independent variables X1 Solar Brightness X4 X5 Extreme Temperature Wind Speed ​​3X Minimal Temperature and Very High Level .

Let X(t) be a homogeneous and continuous stochastic process with independent increments. The subject of this paper is to characterize the stable process by two identically distributed stochastic integrals formed by means of X(t) (in the sense of convergence in probability). The proof of the main results is based on a modern extension of the Phragmén-Lindelöf theory.

Ruth, a tale of human kindness and just dealing far beyond the norm, contains elements that for centuries have been the subject of debate. With a sprightly translation and a commentary rich in informed speculation, Professor Campbell considers the questions of layman and scholar alike. Finding no overt mighty acts, the layman asks, “Why was Ruth included in the Bible at all? Where is God?” Professor Campbell shows that God is not only present throughout but is indeed the moving force behind all the developments of the story. Naomi, Ruth, and Boaz each act as God to each other, by taking extraordinary responsibility and performing extraordinary acts of kindness. And it is God who is responsible for the series of coincidences on which the plot hinges. The scholar’s questions deal with such matters as purpose, date, and genre. Professor Campbell’s research into ancient customs and linguistics suggests to him that Ruth is a historical novelette, entertaining and instructive, composed not long after the reign of King David, during the time of Solomon or within the subsequent century. Professor Campbell demonstrates the storyteller’s skill with sensitive analysis of form, pacing, and wordplay. By delving into word origins and nuances he shows how convincingly the characters are developed. One instance: Naomi and Boaz use obsolescent language, emphasizing the generation gap between them and Ruth. In addition, the illustrations help the reader understand unfamiliar elements of the story—the setting, the agricultural seasons and harvesting, the clothing of the times, the city gate where elders and interested villagers gather to make sure that all is done in a just and godly way.

Abu Zayd believes that understanding the Qur'an is not limited to explanations or comments. It involves an interpretation process for capturing the significance (maghza) from the literal text. Interpretation also requires a presupposition that the Qur'an itself does not produce literal absolutes and certainty. The presupposition needs an interpretation that illustrates the possibility of accepting the diversity of Qur'anic interpretations in the times. By using Abu Zayd's hermeneutics, the Qur'an is an icon of Islam and at the same time a representation of Arab culture itself which is not necessarily literally absolute, but is open to interpretation. Hans Georg Gadamer's hermeneutic circle that inspired Hermeneutics of Abu Zayd emphasized that in understanding and applying the meanings of the text, the subject played a role in the text rather than the other way around. This study aims to open opportunities that the Qur'an on the one hand is an objective thing seen from the content of its truth, that is seen from its universal message, but on the other hand it is subjective, because it is bound by the interpretation of the text. This research is also intended to avoid the sacredness of the ordination of a single interpretation of the Qur'an which has resulted in the emergence of fundamentalism which has recently become so prevalent in global Islamic societies, not least in Indonesia.

The article introduces a method of performing a radio link quality assessment based on the Link Quality Indicator (LQI) which will be calculated for every system that is available. The method presented has been developed during the netBaltic project completed in Poland and generally applies to the so-called maritime zone A, i.e. the sea area where ships are still within the range of shore-based radio communication systems, particularly 3G/LTE cellular networks. The algorithm was developed based on the results of measurements obtained during two separate campaigns. That measurement data served as a basis for the method’s initial assumptions and was utilized during the method’s verification.

This book is about one of the most intriguing features of human communication systems: the fact that words which go together in meaning can occur arbitrarily far away from each other. The kind of long-distance dependency that this volume is concerned with has been the subject of intense linguistic and psycholinguistic research for the last half century, and offers a unique insight into the nature of grammatical structures and their interaction with cognition. The constructions in which these unbounded dependencies arise are difficult to model and come with a rather puzzling array of constraints which have defied characterization and a proper explanation. For example, there are filler-gap dependencies in which the filler phrase is a plural phrase formed from the combination of each of the extracted phrases, and there are filler-gap constructions in which the filler phrase itself contains a gap that is linked to another filler phrase. What is more, different types of filler-gap dependency can compound, in the same sentence. Conversely, not all kinds of filler-gap dependencies are equally licit; some are robustly ruled out by the grammar whereas others have a less clear status because they have graded acceptability and can be made to improve in ideal contexts and conditions. This work provides a detailed survey of these linguistic phenomena and extant accounts, while also incorporating new experimental evidence to shed light on why the phenomena are the way they are and what important research on this topic lies ahead.
