Elements of Numerical Relativity : From Einstein`s Equations to Black Hole Simulations
Spurred by the current development of numerous large-scale projects for detecting gravitational radiation, with the aim to open a completely new window to the observable Universe, numerical relativity has become a major field of research over the past years. Indeed, numerical relativity is the standard approach when studying potential sources of gravitational waves, where strong fields and relativistic velocities are part of any physical scenario. This book can be considered a primer for both graduate students and non-specialist researchers wishing to enter the field. Starting from the most basic insights and aspects of numerical relativity, Elements of Numerical Relativity develops coherent guidelines for the reliable and convenient selection of each of the following key aspects: evolution formalism, gauge, initial and boundary conditions as well as various numerical algorithms. The tests and applications proposed in this book can be performed on a standard PC.

Econometric Analysis of Count Data
The book provides graduate students and researchers with an up-to-date survey of statistical and econometric techniques for the analysis of count data, with a focus on conditional distribution models. Proper count data probability models allow for rich inferences, both with respect to the stochastic count process that generated the data, and with respect to predicting the distribution of outcomes. The book starts with a presentation of the benchmark Poisson regression model. Alternative models address unobserved heterogeneity, state dependence, selectivity, endogeneity, underreporting, and clustered sampling. Testing and estimation is discussed from frequentist and Bayesian perspectives. Finally, applications are reviewed in fields such as economics, marketing, sociology, demography, and health sciences. The fifth edition contains several new topics, including copula functions, Poisson regression for non-counts, additional semi-parametric methods, and discrete factor models. Other sections have been reorganized, rewritten, and extended.
Eating disorders
What is an Eating Disorder (ED)? Eating disorders are a type of serious mental health condition characterized by severe disturbances in eating behaviors and related to persistent eating behaviors that negatively impact your health, your emotions and your ability to function in important areas of life. Most eating disorders involve focusing too much on your weight, body shape and food, leading to dangerous eating behaviors. These behaviors can significantly impact your body's ability to get appropriate nutrition. Eating disorders can harm the heart, digestive system, bones, and teeth and mouth, and lead to other diseases. Eating disorders affect several million people at any given time, ED often develop in the teen and young adult years, although they can develop at other ages. Eating disorders can affect people of all genders, ages, races, religions, ethnicities, sexual orientations, body shapes, and weights.
Earthquake alert with smartwatch = تنبيه الزلازل باستخدام الساعة الذكية
After the recent events and earthquakes that affected the region, resulting in the deaths of many individuals due to the lack of timely emergency response, the idea for this project emerged Earthquake Alert with Smartwatch. Initially, our application gathers information about the user, such as age, family members, and any existing medical conditions. In the event of an earthquake, the application sends an alert to the user. It receives earthquake information, such as ‘magnitude, time, location…’ from United States Geological Survey “USGS” through an API. If the user is within the geographical area affected by the earthquake, the application will assist the Smartwatch in calculating vital signs such as ‘heart rate and blood pressure’. Additionally, there is another artificial intelligence model that receives the user's audio recordings and converts them into written texts. All this information, along with the user's geographical location, will be sent to the nearest emergency point for the purpose of aiding those individuals trapped under the rubble.
Earth Observation of Global Change : The Role of Satellite Remote Sensing in Monitoring the Global Environment
Global Change is increasingly considered a critical topic in environmental research. Remote sensing methods provide a relevant tool to monitor global variables, since they offer a systematic coverage of the Earth Surface, at different spatial, spectral and temporal resolutions. The data provided by Earth Observation Satellites are being operationally used for monitoring atmospheric conditions, ice sheets and glaciar movements, crop dynamism and land use changes, deforestation and desertification processes, as well as water conditions. The book includes an analysis of the leading missions in global Earth observation, and then reviews the main fields in which remote sensing methods are providing vital data for global change studies.
Early Development of the Human Pelvic Diaphragm
A sound and detailed knowledge of the anatomy of the pelvic floor is of the utmost importance to gynecologists, obstetricians, surgeons, and urologists, since they all share the same responsibility in treating patients with different pathological conditions caused by pelvic floor dysfunction. The most common clinical expressions of pelvic floor dysfunction are urinary incontinence, anal incontinence, and pelvic organ prolapse. Most often these clinical expressions are found in women, and they are briefly discussed below based on the outline presented in the Third International Consultation on Incontinence, a joint effort of the International Continence Society and the World Health Organization.

Disordered Materials : An Introduction
This self-contained text introduces the physics of structurally disordered condensed systems at the level of advanced undergraduate and graduate students. Among the topics are the geometry and symmetries of the structural units used as building blocks of extended structures, the various kinds of disorder, the phenomenology and the main theories of the glass transition, the structure of amorphous systems and the techniques to investigate it, the evolution of system's structure with its size (clusters) and the presence of orientational order in the absence of translational order (quasicrystals). In the second edition, the treatment of the mode coupling theory of the glass transition has been enlarged and connects now to a new section on collective excitations in disordered systems. Special attention has been devoted to nanometer-sized disordered systems, with emphasis on cluster-assembled materials. Questions of what governs the occurrence and stability of quasicrystals, the features of the amorphous to quasicrystal transformation and its reverse transition are discussed. The conditions leading to nano-quasicrystalline phases of technological interest are examined. Throughout the text relevant recent experimental and theoretical results are discussed so as to give readers insight into the currently most vibrant research topics.
