This book presents an analytical framework for calculating the fracture toughness of generally layered beam structures with an elastically coupled response and hygrothermal stresses. The beam under study features several peculiarities: it consists of multiple layers of dissimilar materials, features bending-extension coupling, and contains residual hygrothermal stresses. Here, a generic analytical model is proposed to compute the energy release rate and the mode mixity. Mechanics of composite materials, crack closure integral, and energetic methods are among the theoretical tools employed for developing the model.A wealth of new closed-form expressions is presented, together with their validation through finite element analyses, which enables investigating various material systems and testing configurations. Experimentalists will find directions for the design and interpretation of delamination tests on laminated composites with uncommon stacking sequences. At the same time, theoreticians can exploit the analytical solution as a benchmark test for more refined analytical and numerical models. Furthermore, the book gives novel insights into the fracture behavior of a titanium-to-CFRP adhesive joint, which is intended for application in the hybrid laminar flow control of a future aircraft. It reports on experiments and theoretical analyses that help understand the behavior of this novel joint. All in all, this book offers extensive updates on methods for fracture analysis of materials with an elastically coupled behavior and residual stresses. It addresses students, researchers, and engineers alike.

The Bioethics of Space Exploration provides a comprehensive discussion of the possible bioethical issues and challenges that may arise when considering future long-term space missions. Because of numerous threats within the space environment, many consider the concept of radically modifying humans to be a serious and perhaps even necessary option. Konrad Szocik presents what types of ethical and bioethical challenges may await participants on commercial, scientific, and colonizing missions, and provides a new perspective into the potential for radical biomedical technologies.

This book describes the development and design of a unique combined data and power management infrastructure for small satellites. This new edition became necessary because in the frame of the system's impressive evolution from an academic prototype to one of today's most advanced core avionics, many elements were upgraded to their next technology generation and diverse new components complement the upgraded design. All elements are presented in updated respectively new chapters.This modular infrastructure was selected by the Swiss start-up ClearSpace SA for ESA's first mission ClearSpace-1 to remove space debris. Furthermore it is the baseline for the Thai national satellite development program and is used by an increasing number of universities worldwide for research studies.

Highly accurate and reliable passenger air travel demand forecasts are critical for airports as they are a key input into airport master plans and they are also used to guide management decisions on airport design and infrastructure planning, airport operations, and resource planning. The objective of this book is to develop and empirically test adaptive neuro-fuzzy inference system (ANFIS) and artificial neural networks (ANNs) to predict airport¿s passenger demand. The study is based on five major airports: Frankfurt Airport, Hong Kong International Airport, Tokyös Narita International Airport, Chicagös O¿Hare International Airport, and Sydney Kingsford Smith Airport, Australia. The performance of the artificial neural network (ANN) and adaptive neuro-fuzzy inference systems models was assessed by five goodness of fit measures: coefficient of determination (R2), mean absolute error (MAE), mean absolute percentage error (MAPE), and root mean squared error (RMSE). Artificial intelligence-based machine learning modelling techniques are worthy of consideration for those interested in forecasting airport passenger demand.

Herein Volume 1, we explore principally relativistic rocket flight in so-called astral planes.Accordingly, we include formulas for relativistic rocket flight performance, fuel supplies, shielding, and the like. In this volume, we cover more or less conventional relativistic rockets and astral planar analogs.We approach the notions of astral planar flight in formulaic detail in the following manners.First, we consider astral planar variables in associated equations and formulas as derived from axiomatic modifications of equations and formulas for conventional relativistic rocket flight.Second, we assume closely parallel formulaic analogs with known relativistic flight formulas under the assumption that since it appears that the laws of physics in our physical realm are the way they are because that is the way they must be for the physical cosmos to per due.Third, we assume that the fundamental constants in astral planar laws are analogs of those in the physical realm and indeed must be so as to provide stability in astral planes and associated rocket travel.Fourth, we assume that no-go theorems such as the chronological protection conjecture and the certainty of light-speed limits in our physical universe have analogs in astral planes.Fifth, we assume that the operation of fiat such as rockets in astral planes operate in close analogies with the operation of such craft as would occur in our physical realm.Sixth, we assume that except for higher levels of intellectual, emotional, social, and psychological functioning in astral planes compared to that of us in the physical realm, astral planar proverbial landscape is similar looking to that of present day physicality. We base this assumption on the common and repeated content of personal accounts of near death experiences and the like and how such experiences are similar to those in the physical world such as the perception of colors, the existence from lush grassy meadow, flowers, animal playing together in the presence of Jesus, and the like.Astral planes are assumed to come in a plethora of levels. The first level is most closely analogous to the physical realm accept at a higher more refined level. In Volume 1, we concern our formulas, natural constants, topologies, geometries and other kinematic aspects in a first level of astral planes as more closely related to that in the visible physical realm.The book is divided into two main parts. The first part considered conventional relativistic rocket flight in the physical realm while the second part considers analogs in a first level of astral planes.In many cases for the portion of the book on astral planar rocket flight, we do not always specifically replace word for word of, say for instance, relativistic rocket with astral-planar relativistic rocket, nor other words of primary themes. However, the context in which dual wordage is provided is made clear in the astral-planar analogues.In Volume 1, we consider astral-planar analogs of relativistic rocket flight in a first level and category of performance, such as for example, conventional relativistic rocket flight in the range of Lorentz factors ranging from just a bit greater than one to values on the order of billions and trillions.

Zweite, vollständig überarbeitete und erweiterte AuflageIn der knapp dreißigjährigen Geschichte der Junkers-Werke entstanden zwischen 1915 und 1945 fast 30.000 Junkers-Flugzeuge. Die meisten dieser Flugzeuge wurden im zweiten Weltkrieg gebaut und gingen während ihres Kriegseinsatzes oft nach nur wenigen Einsatztagen verloren. Das, was am Ende des verlorenen Kriegs übrig blieb, war wertvoller Rohstoff und wurde zur Rohstoffgewinnung verschrottet. Hiervon blieben in Deutschland auch die Flugzeuge nicht verschont, die schon in den zwanziger und dreißiger Jahren als technisches Kulturgut in eines der aufstrebenden Technikmuseen gelangten. Einige wurden bei alliierten Bomberangriffen zerstört. Andere verschwanden auf dem Weg in vermeintlich sichere Lagerstellen. Anfang der fünfziger Jahre existierte in Deutschland keines der 30.000 Junkers-Flugzeuge mehr. Die heute noch existierenden, annähernd 100 Originalflugzeuge überstanden den Krieg durchweg außerhalb Deutschlands. Einige von ihnen haben inzwischen den Weg zurück in deutsche Luftfahrtmuseen gefunden. Eine Reihe guter Nachbauten ergänzt die wenigen Originale.Die vorliegende Buchreihe ist eine Bestandsaufnahme der heute noch existierenden Junkers-Flugzeuge, sowie der inzwischen entstandenen Nachbauten und dokumentiert die individuelle Geschichte dieser Exponate. Der erste Band widmet sich den frühen Flugzeugentwicklungen, die unter der Leitung von Hugo Junkers bis 1932 entstanden sind. Die noch zahlreich vorhandenen Junkers Ju52 sind Gegenstand des zweiten Bandes, während die Flugzeugentwicklungen nach der Zeit von Hugo Junkers in einem abschließenden dritten Band behandelt werden.Fünf Jahre nach Erscheinen der Erstauflage des ersten Bandes legen wir mit dieser Zweitauflage nicht nur eine einfache Aktualisierung vor. Zahlreiche neue Objekte, zum Teil auch Originalflugzeuge, die aus Lagerresten unerwartet wieder zusammengesetzt werden konnten, die Wiederaufnahme einer Serienfertigung flugfähiger Junkers-Nachbauten bei der neu gegründeten Junkers Flugzeugwerke AG in der Schweiz, sowie die Neu- und Umgestaltung zahlreicher Flugzeugsammlungen machten eine grundlegende Überarbeitung des Inhalts der Erstaufgabe erforderlich.

Die Mikrogravitationsumgebung ist eine hervorragende Plattform für Forschung, Anwendung und Ausbildung. Es ist eine Umgebung, in der Schwerelosigkeit vorausgesetzt wird. Alle Experimente, die unter 1G durchgeführt werden, können unter Mikrogravitation wiederholt werden, wenn sie verfügbar sind, ebenso können neue Experimente formuliert werden, um die unter 1G erzielten Ergebnisse mit der Mikrogravitation zu vergleichen. Weltraumtaugliche Experimente in der Mikrogravitation sind ungewöhnlich und teuer, was die Zahl der Forscher in diesem Bereich einschränkt. Auf der Erde stehen Plattformen zur Verfügung, die im freien Fall, in Ballons, Sondierungsraketen usw. Schwerelosigkeit erfahren; diese Plattformen reagieren schnell, während einige Experimente nur langsam auf die Mikrogravitation reagieren. Dies führte zur Entwicklung mehrerer alternativer bodengestützter Geräte zur Simulation der Mikrogravitation bzw. der Aufhebung der Schwerkraft. Clinostat ist eines dieser Geräte. In diesem Buch werden die möglichen Proben und die experimentellen Variablen für den 2D-Klinostat beschrieben. Außerdem werden die Vorteile der Mikrogravitationsforschung im Hinblick auf ihre Anwendung in der Ausbildung und in den Biowissenschaften (Landwirtschaft, Pharmazie, Mikrobiologie, Medizin und Biotechnologie) am Beispiel des Klinostats aufgezeigt.

What has motivated the knowledge and development of human beings? The answer is simple, because since time immemorial curiosity has been the propelling agent of the development of our existence and of the different civilizations. This concept has been helped by the observation from a distance and from space with information provided by artificial satellites created precisely for the study and location of various phenomena and changes occurring on the earth's surface, and that in our era point to a joint and collaborative work between different specialties.

Che cosa ha motivato la conoscenza e lo sviluppo dell'uomo? La risposta è semplice, perché da sempre la curiosità è il motore dello sviluppo della nostra esistenza e delle diverse civiltà. Questo concetto è stato favorito dall'osservazione a distanza e dallo spazio con le informazioni fornite dai satelliti artificiali creati proprio per lo studio e la localizzazione dei vari fenomeni e cambiamenti che avvengono sulla superficie terrestre, e che nella nostra epoca puntano a un lavoro congiunto e collaborativo tra diverse specialità.

This study mainly developed a mapping method and assessed the risk of flooding in urban areas, adapted to the context of anarchic urbanization and poorly controlled sanitation in the municipality of Abobo (Abidjan, Côte d'Ivoire). It was broken down into three specific objectives: First, the identification of hazard and vulnerability factors at the origin of flooding; Second, the mapping of flood risk areas, based on Saaty's AHP Multicriteria Analysis; Third, the modeling of the rainfall runoff system, at the scale of the Sagbé-Anonkoi Kouté watershed, in order to establish a projection of flooding over the periods of 5, 25, 50, and 100 years, with a view to assisting decision-makers in considering anticipatory decisions.

Questo studio ha sviluppato principalmente un metodo di mappatura e ha valutato il rischio di inondazioni in un ambiente urbano, adattato al contesto di urbanizzazione anarchica e di servizi igienici scarsamente controllati nel comune di Abobo (Abidjan, Costa d'Avorio). È stato suddiviso in tre obiettivi specifici: In primo luogo, l'identificazione dei fattori di pericolosità e vulnerabilità all'origine delle alluvioni; in secondo luogo, la mappatura delle aree a rischio di alluvione, basata sull'analisi multicriteriale AHP di Saaty; in terzo luogo, la modellazione del sistema di deflusso delle precipitazioni, alla scala del bacino idrografico di Sagbé-Anonkoi Kouté, al fine di stabilire una proiezione delle alluvioni su periodi di 5, 25, 50 e 100 anni, con l'obiettivo di aiutare i decisori a prendere decisioni anticipate.
