Available in PDF, EPUB and Kindle. Book excerpt: In How to Kill a Dragon Calvert Watkins follows the continuum of poetic formulae in Indo-European languages, from Old Hittite to medieval Irish. He uses the comparative method to reconstruct traditional poetic formulae of considerable complexity that stretch as far back as the original common language. Thus, Watkins reveals the antiquity and tenacity of the Indo-European poetic tradition. Watkins begins this study with an introduction to the field of comparative Indo-European poetics; he explores the Saussurian notions of synchrony and diachrony, and locates the various Indo-European traditions and ideologies of the spoken word. Further, his overview presents case studies on the forms of verbal art, with selected texts drawn from Indic, Iranian, Greek, Latin, Hittite, Armenian, Celtic, and Germanic languages. In the remainder of the book, Watkins examines in detail the structure of the dragon/serpent-slaying myths, which recur in various guises throughout the Indo-European poetic tradition. He finds the "signature" formula for the myth--the divine hero who slays the serpent or overcomes adversaries--occurs in the same linguistic form in a wide range of sources and over millennia, including Old and Middle Iranian holy books, Greek epic, Celtic and Germanic sagas, down to Armenian oral folk epic of the last century. Watkins argues that this formula is the vehicle for the central theme of a proto-text, and a central part of the symbolic culture of speakers of the Proto-Indo-European language: the relation of humans to their universe, the values and expectations of their society. Therefore, he further argues, poetry was a social necessity for Indo- European society, where the poet could confer on patrons what they and their culture valued above all else: "imperishable fame."

This book was released on 2005 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the pages of the Sharafnama are present the Kurdish nation, already unified 400 years ago within a common culture, national ethos, a defined homeland and an integrated history stretching into antiquity. In the text of this unique history the empires of the Kurds parallel those of the Arabs, Persians and Turks, some, according to Bitlisi, reaching back over 4,000 years. As the Kurds continue their arduous journey to regain their proper position as the fourth largest ethnic group in the greater Middle East, it is clear why the Sharafnama has gained the status of a national document and the locus classicus of Kurdish authenticity. The great prestige of the Sharafnama as a national history among the Kurdish literati and rulers has lasted for centuries. To gain the honor of being mentioned in the Sharafnama enticed later Kurdish dynasties to shuffle their own dynastic history into the pages of the book long after Bitlisi's death. Meanwhile, due to the pristine condition of its surviving manuscripts, the Sharafnama has and continues to serve as a primary resource to compare and correct the scribal errors found in other histories written in Persian language before 1597. The Sharafnama also contains invaluable information on the Kurds' neighboring peoples and dynasties who interacted with the Kurds, as well as the empires that emerged and weathered in the area."

Book excerpt: A beautifully illustrated collection of mindfulness exercises for grounding, relaxation, and finding inner peace, from contemporary mystic Osho All of us have experienced moments of "coming home"--feeling relaxed, grounded, free of the restlessness that characterizes so much of our everyday lives. These moments can arise in nature or in the depths of an activity we enjoy, alone or together with people we love. They show us that we are exactly where we are supposed to be. The meditations in Coming Home to Yourself were selected from Osho's hundreds of public talks and intimate conversations. These passages are designed to be a companion on the journey toward transforming our rare moments of "at-home-ness" into an undercurrent that permeates all aspects of our lives. They offer guidance about meditation and specific techniques to try, insights into the habits that keep us tense and conflicted, and what life might look like if we recognize those habits and let them go. Exercises include activating your awareness, opening the heart, learning to relax and concentrate in order to reap the benefits of meditation, and freeing the brain from mental blocks. Featuring whimsical full color illustrations throughout, Coming Home to Yourself invites the reader to dip into the meditations at any point or read the book in sequence for a true homecoming experience.

Available in PDF, EPUB and Kindle. Book excerpt: Through creative combinations of ethnohistoric evidence, iconography, and contextual analysis of faunal remains, this work offers new insight into the mechanisms involved in food provisioning for complex societies. Contributors combine zooarchaeological and historical data from global case studies to analyze patterns in centralization and bureaucratic control, asymmetrical access and inequalities, and production-distribution-consumption dynamics of urban food provisioning and animal management. Taking a global perspective and including both prehistoric and historic case studies, the chapters in the volume reflect some of the current best practices in the zooarchaeology of complex societies. Embedding faunal evidence within a broader anthropological explanatory framework and integrating archaeological contexts, historic texts, iconography, and ethnohistorical sources, the book discerns myriad ways that animals are key contributors to, and cocreators of, complex societies in all periods and all places. Chapters cover the diverse sociopolitical and economic roles wild animals played in Bronze Age Turkey; the production and consumption of animal products in medieval Ireland; the importance of belief systems, politics, and cosmologies in Shang Dynasty animal provisioning in the Yellow River Valley; the significance of external trade routes in the kingdom of Aksum (modern Sudan); hunting and animal husbandry at El Zotz; animal economies from two Mississippian period sites; and more. Food Provisioning in Complex Societies provides an optimistic roadmap and heuristic tools to explore the diverse, resilient, and contingent processes involved in food provisioning. The book represents a novel and productive way forward for understanding the unique, yet predictably structured, provisioning systems that emerged in the context of complex societies in all parts of the world. It will be of interest to zooarchaeologists and archaeologists alike. Contributors: Joaquin Arroyo-Cabrales, Fiona Beglane, Roderick Campbell, Kathryn Grossman, Patricia Martinez-Lira, Jacqueline S.

Book excerpt: This book provides a comprehensive overview of the emerging technologies for next-generation 5G mobile communications, with insights into the long-term future of 5G. Written by international leading experts on the subject, this contributed volume covers a wide range of technologies, research results, and networking methods. Key enabling technologies for 5G systems include, but are not limited to, millimeter-wave communications, massive MIMO technology and non-orthogonal multiple access. 5G will herald an even greater rise in the prominence of mobile access based upon both human-centric and machine-centric networks. Compared with existing 4G communications systems, unprecedented numbers of smart and heterogeneous wireless devices will be accessing future 5G mobile systems. As a result, a new paradigm shift is required to deal with challenges on explosively growing requirements in mobile data traffic volume (1000x), number of connected devices (10–100x), typical end-user data rate (10–100x), and device/network lifetime (10x). Achieving these ambitious goals calls for revolutionary candidate technologies in future 5G mobile systems. Designed for researchers and professionals involved with networks and communication systems, 5G Mobile Communications is a straightforward, easy-to-read analysis of the possibilities of 5G systems.

Download or read book Spatial Resource Allocation in Massive MIMO Communications written by Trinh Van Chien and published by Linköping University Electronic Press. This book was released on 2019-12-09 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Massive MIMO (multiple-input multiple-output) is considered as an heir of the multi-user MIMO technology and it has gained lots of attention from both academia and industry since the last decade. By equipping base stations (BSs) with hundreds of antennas in a compact array or a distributed manner, this new technology can provide very large multiplexing gains by serving many users on the same time-frequency resources and thereby bring significant improvements in spectral efficiency (SE) and energy efficiency (EE) over the current wireless networks. The transmit power, pilot training, and spatial transmission resources need to be allocated properly to the users to achieve the highest possible performance. This is called resource allocation and can be formulated as design utility optimization problems. If the resource allocation in Massive MIMO is optimized, the technology can handle the exponential growth in both wireless data traffic and number of wireless devices, which cannot be done by the current cellular network technology. In this thesis, we focus on the five different resource allocation aspects in Massive MIMO communications: The first part of the thesis studies if power control and advanced coordinated multipoint (CoMP) techniques are able to bring substantial gains to multi-cell Massive MIMO systems compared to the systems without using CoMP. More specifically, we consider a network topology with no cell boundary where the BSs can collaborate to serve the users in the considered coverage area. We focus on a downlink (DL) scenario in which each BS transmits different data signals to each user. This scenario does not require phase synchronization between BSs and therefore has the same backhaul requirements as conventional Massive MIMO systems, where each user is preassigned to only one BS. The scenario where all BSs are phase synchronized to send the same data is also included for comparison. We solve a total transmit power minimization problem in order to observe how much power Massive MIMO BSs consume to provide the requested quality of service (QoS) of each user. A max-min fairness optimization is also solved to provide every user with the same maximum QoS regardless of the propagation conditions. The second part of the thesis considers a joint pilot design and uplink (UL) power control problem in multi-cell Massive MIMO. The main motivation for this work is that the pilot assignment and pilot power allocation is momentous in Massive MIMO since the BSs are supposed to construct linear detection and precoding vectors from the channel estimates. Pilot contamination between pilot-sharing users leads to more interference during data transmission. The pilot design is more difficult if the pilot signals are reused frequently in space, as in Massive MIMO, which leads to greater pilot contamination effects. Related works have only studied either the pilot assignment or the pilot power control, but not the joint optimization. Furthermore, the pilot assignment is usually formulated as a combinatorial problem leading to prohibitive computational complexity. Therefore, in the second part of this thesis, a new pilot design is proposed to overcome such challenges by treating the pilot signals as continuous optimization variables. We use those pilot signals to solve different max-min fairness optimization problems with either ideal hardware or hardware impairments. The third part of this thesis studies a two-layer decoding method that mitigates inter-cell interference in multi-cell Massive MIMO systems. In layer one, each BS estimates the channels to intra-cell users and uses the estimates for local decoding within the cell. This is followed by a second decoding layer where the BSs cooperate to mitigate inter-cell interference. An UL achievable SE expression is computed for arbitrary two-layer decoding schemes, while a closed form expression is obtained for correlated Rayleigh fading channels, maximum-ratio combining (MRC), and largescale fading decoding (LSFD) in the second layer. We formulate a sum SE maximization problem with both the data power and LSFD vectors as optimization variables. Since the problem is non-convex, we develop an algorithm based on the weighted minimum mean square error (MMSE) approach to obtain a stationary point with low computational complexity. Motivated by recent successes of deep learning in predicting the solution to an optimization problem with low runtime, the fourth part of this thesis investigates the use of deep learning for power control optimization in Massive MIMO. We formulate the joint data and pilot power optimization for maximum sum SE in multi-cell Massive MIMO systems, which is a non-convex problem. We propose a new optimization algorithm, inspired by the weighted MMSE approach, to obtain a stationary point in polynomial time. We then use this algorithm together with deep learning to train a convolutional neural network to perform the joint data and pilot power control in sub-millisecond runtime. The solution is suitable for online optimization. Finally, the fifth part of this thesis considers a large-scale distributed antenna system that serves the users by coherent joint transmission called Cell-free Massive MIMO. For a given user set, only a subset of the access points (APs) is likely needed to satisfy the users' performance demands. To find a flexible and energy-efficient implementation, we minimize the total power consumption at the APs in the DL, considering both the hardware consumed and transmit powers, where APs can be turned off to reduce the former part. Even though this is a nonconvex optimization problem, a globally optimal solution is obtained by solving a mixed-integer second-order cone program (SOCP). We also propose low-complexity algorithms that exploit group-sparsity or received power strength in the problem formulation.

Download or read book Optimizing Massive MIMO written by Hei Victor Cheng and published by Linköping University Electronic Press. This book was released on 2018-04-11 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decades have seen a rapid growth of mobile data traffic,both in terms of connected devices and data rate. To satisfy the evergrowing data traffic demand in wireless communication systems, thecurrent cellular systems have to be redesigned to increase both spectralefficiency and energy efficiency. Massive MIMO(Multiple-Input-Multiple-Output) is one solution that satisfy bothrequirements. In massive MIMO systems, hundreds of antennas areemployed at the base station to provide service to many users at thesame time and frequency. This enables the system to serve the userswith uniformly good quality of service simultaneously, with low-costhardware and without using extra bandwidth and energy. To achievethis, proper resource allocation is needed. Among the availableresources, transmit power beamforming are the most important degrees offreedom to control the spectral efficiency and energy efficiency. Dueto the use of excessive number of antennas and low-end hardware at thebase station, new aspects of power allocation and beamforming compared to currentsystems arises. In the first part of the thesis, new uplink power allocation schemes that based on long term channel statistics isproposed. Since quality of the channel estimates is crucial in massive MIMO, in addition to data power allocation, joint power allocationthat includes the pilot power as additional variable should be considered. Therefore a new framework for power allocation thatmatches practical systems is developed, as the methods developed in the literature cannot be applied directly to massive MIMO systems. Simulation results confirm the advantages brought by the the proposed new framework. In the second part, we introduces a new approach to solve the joint precoding and power allocation for different objective in downlink scenarios by a combination of random matrix theory and optimization theory. The new approach results in a simplified problem that, though non-convex, obeys a simple separable structure. Simulation results showed that the proposed scheme provides large gains over heuristic solutions when the number of users in the cell is large, which is suitable for applying in massive MIMO systems. In the third part we investigate the effects of using low-end amplifiers at the basestations. The non-linear behavior of power consumption in these amplifiers changes the power consumption model at the basestation, thereby changes the power allocation and beamforming design. Different scenarios are investigated and resultsshow that a certain number of antennas can be turned off in some scenarios. In the last part we consider the use of non-orthogonal-multiple-access (NOMA) inside massive MIMO systems in practical scenarios where channel state information (CSI) is acquired through pilot signaling. Achievable rate analysis is carried out for different pilot signaling schemes including both uplink and downlink pilots. Numerical results show that when downlink CSI is available at the users, our proposed NOMA scheme outperforms orthogonal schemes. However with more groups of users present in the cell, it is preferable to use multi-user beamforming in stead of NOMA.
