Ons praat Afrikaans – diverse mense – een taal is meer as net nog ’n fotoboek: dit is die eindproduk van ’n projek wat sy ontstaan gevind het in een individu se liefde vir die Afrikaanse kultuur en taal, Douw Greeff. Die projek is geloods in 2016 toe fotograwe (amateur en ook professioneel) genader is om werke in te skryf wat hulle voel die Afrikaanse kultuur en taal raakvat. Verskeie inskrywings is ontvang en die top foto’s het deurgegaan na ’n beoordelings-rondte, waar ’n paneel die beste foto’s gekies het om in hierdie pragpublikasie te pronk.

Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

This book presents a comprehensive overview of wireless sensor networks (WSNs) with an emphasis on security, coverage, and localization. It offers a structural treatment of WSN building blocks including hardware and protocol architectures and also provides a systems-level view of how WSNs operate. These building blocks will allow readers to program specialized applications and conduct research in advanced topics. A brief introductory chapter covers common applications and communication protocols for WSNs. Next, the authors review basic mathematical models such as Voroni diagrams and Delaunay triangulations. Sensor principles, hardware structure, and medium access protocols are examined. Security challenges ranging from defense strategies to network robustness are explored, along with quality of service measures. Finally, this book discusses recent developments and future directions in WSN platforms. Each chapter concludes with classroom-tested exercises that reinforce key concepts. This book is suitable for researchers and for practitioners in industry. Advanced-level students in electrical engineering and computer science will also find the content helpful as a textbook or reference.

This book provides a unique study of the differences in economic behaviour according to the phases of the economic cycle in the countries of the European Union. It presents a comprehensive analysis of asymmetry in the EU over the last forty years, and shows that the problems in the global financial crisis were readily predictable.
The authors use empirical research and panel data to show how much economic behaviour changes between the up and down phases of the business cycle, and the difficulties this creates for monetary, fiscal and labour market policies. The volume demonstrates how prescient the asymmetric design of the Stability and Growth Pact was in trying to offset countries understandable optimism in fiscal policy, and the consequent tendency not to manage debt successfully. It also reveals the inherent problems for managing unemployment in an asymmetric labour market.

This book deciphers the intricacies of the compatibility of zodiac signs, the attraction between people of diverse temperaments and what leads to romantic alliances and conjugal ties.

Supervisory Control Theory (SCT) provides a tool to model and control human-engineered complex systems, such as computer networks, World Wide Web, identification and spread of malicious executables, and command, control, communication, and information systems. Although there are some excellent monographs and books on SCT to control and diagnose discrete-event systems, there is a need for a research monograph that provides a coherent quantitative treatment of SCT theory for decision and control of complex systems. This new monograph will assimilate many new concepts that have been recently reported or are in the process of being reported in open literature. The major objectives here are to present a) a quantitative approach, supported by a formal theory, for discrete-event decision and control of human-engineered complex systems; and b) a set of applications to emerging technological areas such as control of software systems, malicious executables, and complex engineering systems. The monograph will provide the necessary background materials in automata theory and languages for supervisory control. It will introduce a new paradigm of language measure to quantitatively compare the performance of different automata models of a physical system. A novel feature of this approach is to generate discrete-event robust optimal decision and control algorithms for both military and commercial systems.

Volksgeneeskuns in Suid-Afrika is ’n versameling van 8705 boererate en het die eerste keer in 1965 verskyn. Vandag, 60 jaar later, lyk die mediese en farmakologiese landskap totaal anders. Daarom is dit so interessant – en soms lagwekkend – om te sien hoe vinnig ons mediese en farmakologiese kennis intussen gevorder het.

Die versameling bevat rate wat op bygeloof of tradisionele mondelinge oorlewering berus. Ander rate maak staat op veldkennis en die botaniese name van middels word verstrek. Daar word raat uitgedeel vir kwale van asma tot ylhoofdigheid.

“Vermaaklike oomblikke is talryk vir die moderne leser – en die algemene gebruik van hondebloed, velle van pas geslagte katte, luislange en dies meer, laat ’n mens verbysterd – tot jy besef met hoeveel radeloosheid daar voor sekere siektes te staan gekom is.” Dr. Dione Prinsloo – geskiedkundige.

In December of 2020, Vir McCoy contracted Covid-19, which then developed into Post-Acute Sequelae Covid (PASC), commonly known as Long Covid or Long-Haul Covid. Drawing on his journey to heal his chronic Lyme disease years earlier, McCoy began collecting intuitive information, as a medical intuitive, and scientific information, as a scientist, about the nature of Long-Haul Covid. Integrating his intuitive impressions with extensive scientific and medical research, as well as other protocols and support group success stories, he developed a comprehensive healing guide for a successful recovery from Long Covid. The author discusses the primary symptoms and predispositions of Long Covid and outlines the basic steps for dealing with each of them, including brain fog, tinnitus, loss of smell and hair, debilitating headaches, hormonal dysregulation, immune malfunction, limbic system dysfunction, gut issues, mental instability, sleeplessness, and intolerance to certain foods. Backed up by more than 350 scientific references, he presents medicines and methods for healing Long Covid, ranging from pharmaceutical, herbal, and homeopathic remedies to breathwork practices, detox therapies, lymph drainage exercises, gut biome restoration, neuroplasticity retraining, immune modulation, and shamanic techniques, as well as meditations and mantras for calming the limbic system and the PTSD that can accompany chronic illness. Detailing the art of “intuitive access,� the author teaches how to discover your own unique remedies and presents a guide for incorporating these intuitive therapies with modern medical treatments and other healing strategies. He also explores the deeper significance of disease and how the “disease� may be teaching us something greater: a way to reclaim our power.

Develops a Comprehensive, Global Model for Contextually Based Processing Systems A new perspective on global information systems operation Helping to advance a valuable paradigm shift in the next generation and processing of knowledge, Introduction to Contextual Processing: Theory and Applications provides a comprehensive model for constructing a contextually based processing system. It explores the components of this system, the interactions of the components, key mathematical foundations behind the model, and new concepts necessary for operating the system. After defining the key dimensions of a model for contextual processing, the book discusses how data is used to develop a semantic model for contexts as well as language-driven context-specific processing actions. It then applies rigorous mathematical methods to contexts, examines basic sensor data fusion theory and applies it to the contextual fusion of information, and describes the means to distribute contextual information. The authors also illustrate a new type of data repository model to manage contextual data, before concluding with the requirements of contextual security in a global environment. This seminal work presents an integrated framework for the design and operation of the next generation of IT processing. It guides the way for developing advanced IT systems and offers new models and concepts that can support advanced semantic web and cloud computing capabilities at a global scale.

Many models in this volume can be used in solving portfolio problems, in assessing forecasts, in understanding the possible effects of shocks and disturbances.

This book deals with the fundamental causes of the Indo-Pak conflict-why it is difficult, if not impossible, to have peace between the two neighbors. Also it explores the short spurt of Pulwama-Balakot stand-off or a game of one-upmanship. It analyses the perennial conflict scenario and goes to stress that for Pakistan, in recent times, there has been no marked change in disincentives (negative stresses) that could compel it to moderate its behavior towards India-and nor there exists a package of incentives (positive stresses) that should force it to go for a change towards peace. All the key stakeholders of Pakistan (including army, ISI and terror outfits), other than the Pak public, will stand to lose if the religion-steeped state turned friendly, or even nonaggressive, towards India. In that situation, it is indeed difficult to comprehend for a logical mind that why should Indian politicians and diplomats hanker for the illusionary scenario of peace to unfold. Let it be clear for one and all that peace (or even normalcy) between India and Pakistan will only be possible under one of the following situations. That' incentives' package (positive stresses) for Pakistan in the event of being friendly is so great that the same can't be resisted. Or, the disincentives for retaining its historical behavior towards India are so great that the same can't be resisted by its army-and ISI combine. As long as one of the above two conditions doesn't materialize, or isn't forced upon, it shall remain just foolhardy for India to expect that things between the two quarrelsome neighbors shall turn towards normalcy.

Magnitude and quality of life as well as sustainable human progress inescapably depend on the state of our environment. The environment, in essence, is a common resource of all the living organisms in the biosphere as well as a vivacious basis of the evolution of life on Earth. A sustainable future broods over a sustainable environment-an environment encompassing life-originating, life-supporting, and life-sustaining uniqueness. A deteriorating environment haplessly sets in appalling conditions leading to shrinkage of life and a halt in human progress. The current global environment scenario is extremely dismal. Environmental disruptions, largely owing to anthropogenic activities, are steadily leading to awful climate change. Horribly advancing toward mass extinction in the near or distant future and posing a threat to our Living Planet, the unabatedly ongoing climate change, in fact, is an unprecedented issue of human concern about life in the recorded human history. How to get rid of the environmental mess and resolve environmental issues leading to climate change mitigation is the foremost challenge facing humanity in our times. There are several measures the whole world is resorting to. They are primarily focused on cutting down excessive carbon emissions by means of development of technological alternatives, for example, increasing mechanical efficiencies and ever-more dependence on clean-energy sources. These are of great importance, but there is yet a natural phenomenon that has been, and will unceasingly be, pivotal to maintain climate order of the Earth. For it to phenomenally boost, we need to explore deeper aspects of environmental science. It is the environmental plant physiology that links us with deeper roots of life. Environmental Plant Physiology: Botanical Strategies for a Climate-Smart Planet attempts to assimilate a relatively new subject that helps us understand the very phenomenon of life that persists in the planet's environment and depends on, and is influenced by, a specific set of operating environmental factors. It is the subject that helps us understand adaptation mechanisms within a variety of habitats as well as the implications of the alterations of environmental factors on the inhabiting organisms, their populations, and communities. Further, this book can also be of vital importance for policy makers and organizations dealing with climate-related issues and committed to the cause of the earth. This book can be instrumental in formulating strategies that can lead us to a climate-smart planet. Features: * Provides ecological basis of environmental plant physiology * Discusses energy, nutrient, water, temperature, allelochemical, and altitude relations of plants * Reviews stress physiology of plants and plants' adaptations to the changing climate * Examines climate-change effects on plant physiology * Elucidates evolving botanical strategies for a climate-smart planet
