Adjustment theory can be regarded as the part of mathematical geodesy that deals with the optimal combination of redundant measurements together with the estimation of unknown parameters. It is essential for a geodesist, its meaning comparable to what mechanics means to a civil engineer or a mechanical engineer. Historically, the first methods of combining redundant measurements originate from the study of three problems in geodesy and astronomy, namely to determine the size and shape of the Earth, to explain the long-term inequality in the motions of Jupiter and Saturn, and to find a mathematical representation of the motions of the Moon. Nowadays, the methods of adjustment are used for a much greater variety of geodetic applications, ranging from, for instance, surveying and navigation to remote sensing and global positioning.

The two main reasons for performing redundant measurements are the wish to increase the accuracy of the results computed and the requirement to be able to check for errors. Due to the intrinsic uncertainty in measurements, measurement redundancy generally leads to an inconsistent system of equations. Without additional criteria, such a system of equations is not uniquely solvable. In this introductory course on adjustment theory, methods are developed and presented for solving inconsistent systems of equations. The leading principle is that of least-squares adjustment together with its statistical properties.

The inconsistent systems of equations can come in many different guises. They could be given in parametric form, in implicit form, or as a combination of these two forms. In each case the same principle of least-squares applies. The algorithmic realizations of the solution will differ however. Depending on the application at hand, one could also wish to choose between obtaining the solution in one single step or in a step-wise manner. This leads to the need of formulating the system of equations in partitioned form. Different partitions exist, measurement partitioning, parameter partitioning, or a partitioning of both measurements and parameters. The choice of partitioning also affects the algorithmic realization of the solution. In this introductory text the methodology of adjustment is emphasized, although various samples are given to illustrate the theory. The methods discussed form the basis for solving different adjustment problems in geodesy.

An open-source textbook covering vector calculus, ordinary and partial differential equations, and Fourier series. The textbook is used in a first-year graduate level course in the Department of Mechanical Engineering at the Colorado School of Mines. It undergoes extensive revisions annually, but is relatively complete.

The purpose of this tutorial (along with the “Advanced Keyword Searching, Part I” tutorial) is to help the student master comprehensive, keyword searching. Performing a truly comprehensive, keyword search is more difficult than performing a similarly thorough, subject heading search. We hope that this tutorial will make the steps involved in this complex process easier to understand and master.

Aerodynamics and Aircraft Performance, 3rd edition is a college undergraduate-level introductory textbook on aircraft aerodynamics and performance. This text is designed for a course in Aircraft Performance that is taught before the students have had any course in fluid mechanics, fluid dynamics, or aerodynamics. The text is meant to provide the essential information from these types of courses that is needed for teaching basic subsonic aircraft performance, and it is assumed that the students will learn the full story of aerodynamics in other, later courses. The text assumes that the students will have had a university level Physics sequence in which they will have been introduced to the most fundamental concepts of statics, dynamics, fluid mechanics, and basic conservation laws that are needed to understand the coverage that follows. It is also assumed that students will have completed first year university level calculus sequence plus a course in multi-variable calculus. Separate courses in engineering statics and dynamics are helpful but not necessary. Any student who takes a course using this text after completing courses in aerodynamics or fluid dynamics should find the chapters of this book covering those subjects an interesting review of the material.

The 236-page text was created specifically for use by undergraduate students in Aerospace Engineering and was based on Professor Marchman’s many years of experience teaching related subject matter as well as his numerous wind tunnel research projects related to aircraft aerodynamics and his personal experience as the owner and pilot of a general aviation airplane. It has been used at Virginia Tech and other universities.

Aerospace Structures by Eric Raymond Johnson is a 600+ page text and reference book for junior, senior, and graduate-level aerospace engineering students. The text begins with a discussion of the aerodynamic and inertia loads acting on aircraft in symmetric flight and presents a linear theory for the status and dynamic response of thin-walled straight bars with closed and open cross-sections. Isotropic and fiber-reinforced polymer (FRP) composite materials including temperature effects are modeled with Hooke’s law. Methods of analyses are by differential equations, Castigliano’s theorems, the direct stiffness method, the finite element method, and Lagrange’s equations. There are numerous examples for the response axial bars, beams, coplanar trusses, coplanar frames, and coplanar curved bars. Failure initiation by the von Mises yield criterion, buckling, wing divergence, fracture, and by Puck’s criterion for FRP composites are presented in the examples.

"Air Safety Investigation – The Journey" is an introductory book that explores the world of air safety investigation. Unlike a how-to manual for investigating aviation accidents, this book focuses on the essential knowledge and mindset required to conduct a safety investigation. It covers the various phases of an investigation, from gathering facts to formulating safety recommendations, with each chapter addressing a different relevant aspect. With the increasing complexity of investigations, critical thinking, logic, and speculation are essential skills for investigators to possess. This book delves into these topics, offering thought-provoking examples and questions to address the challenges of drawing conclusions and obtaining positive investigative outcomes. Its aim is to help students and readers interested in air safety develop the necessary mindset and knowledge to conduct an investigation. By the end of the book, readers will gain a deeper understanding of the complexities involved in an air safety investigation.

This is a textbook for first year Computer Science. Algorithms and Data Structures With Applications to Graphics and Geometry.

Short Description:
This book explores the topic of anxiety disorders. Including information on neuroscience, assessment, and intervention.

Long Description:
Anxiety disorders are one of the most common mental health disorders experienced by people in the United States. However, given their complexity, they are also one of the most misunderstood. While these disorders can be quite debilitating, appropriate assessment, diagnosis, and treatment planning are critical to the recovery process.

The chapters introduce the reader to a variety of topics. The chapters include introduction to anxiety and the nervous system, building blocks of anxiety, assessing anxiety, and cognitive and behavioral interventions. The chapters were written to build upon one another. Thus, skipping a chapter and jumping ahead can be problematic as the reader may have missed foundational material in the prior chapters.

I would like to acknowledge that as part of this open educational resource product, there were several mental health providers that peer-reviewed these chapters. I would like to extend a deep gratitude for their time, edits, and constructive feedback.

Le diagnostic est défini comme l’ensemble des mesures réalisées afin d’identifier la nature et la cause des pathologies. Cette recherche est par essence imparfaite et tout thérapeute visera, autant que faire se peut, à s’approcher au plus près du diagnostic. Dans ce processus, plusieurs modalités (anamnèse, examen clinique et examens complémentaires) seront nécessaires tout en restant insuffisantes - ou pour le moins imprécises - lorsqu’elles seront considérées de manière isolée. Au final, c’est la synthèse de ces données qui nous offrira la meilleure vision d’une pathologie nécessairement spécifique et individuelle. La médecine se trouve à mi-distance entre les sciences exactes et les sciences humaines. Certains la définissent aussi comme un art, c’est-à-dire comme une capacité individuelle qu’aurait chaque médecin à soigner. En partie en réaction avec cette idée, depuis une trentaine d’années, l’Evidence Based Medicine s’est progressivement imposée dans les parcours thérapeutiques en même temps qu’une multitude de nouveaux examens complémentaires. Cette évolution vers davantage de science se voit aujourd’hui modérée par un retour progressif à une prise en charge plus globale des patients et c’est probablement à mi-chemin que se trouvera la meilleure stratégie. L’avantage de cette méthode est appuyé par la littérature scientifique actuelle qui montre, chaque jour un peu plus, l’interconnexion des différentes pathologies là-même où nous aurions pensé les séparer par une frontière bien nette. La prise en charge du patient dans sa globalité est garantie par un interrogatoire et un examen clinique bien conduits. Eux seuls peuvent efficacement orienter la nécessité d’examens complémentaires dont la précision extrême reste limitée soit dans l’espace (une IRM lombaire ne couvre que quelques vertèbres…) soit par leur technologie (faible résolution spatiale de la scintigraphie...). La pathologie rachidienne est décrite, à cause de sa prévalence, comme la pathologie du siècle. Elle constitue un des premiers motifs de consultation. Son impact est important sur le plan socio-économique et sur le plan de la santé publique. En effet, en termes d’invalidité, les problèmes lombaires sont au premier plan, suivis par la dépression et les autres affections musculo-squelettiques. Le vieillissement de nos populations s’accompagne d’une augmentation des pathologies dégénératives - y compris rachidiennes - associant des symptômes d’enraidissement, de douleur, de déformation ou de déficit neurologique. Dans ce chapitre, nous nous efforcerons de mettre en lumière les éléments fondamentaux à recueillir dans le cadre d’une consultation en pathologie rachidienne. Il ne s’agit donc pas d’une description exhaustive de l’ensemble des techniques d’interrogatoire et d’examen clinique mais plutôt d’un recueil d’étapes nécessaires pour pouvoir s’orienter correctement et parler un même langage.

Short Description:
This textbook is designed to actively engage your exploration and critical analysis of human anatomical variation in an Australian and New Zealand context. Understanding anatomical variation is essential for all health professionals to avoid patient misdiagnosis such as confusing a natural variant with a pathology, minimise surgical or procedural errors that may occur if variations are unexpected, and ultimately improve patient outcomes by applying culturally safe practices. Research in anatomical variation has demonstrated significant differences in phenotypic expression of variants between and within geographic, ancestral and socioeconomic populations, as well as displaying significant variance between males and females. It is therefore critical as a health professional to understand anatomical variation in the context of the population you intend to practice in. This textbook compiles this critical information into an easy to read summary of the range and frequency of anatomical phenotypes in Australian and New Zealand patients by drawing from contemporary anatomical science research. Anatomical variation of Aboriginal, Torres Strait Islander and Māori peoples has also been highlighted where research is available.

Long Description:
The anatomy of our outwardly facing physical appearance exhibits great diversity between individuals, from different eye, skin and hair colour to the size of our feet and our height. However, it is less known whether our anatomy differs beneath the surface… is the anatomy of the internal organs the same between individuals? Most textbooks would like you to think so with simplified standard descriptions of human anatomy such as the lung lobes and fissures, aortic arch branches and bone numbers. But this eBook is different. Here we build your understanding of the scope and clinical importance of human anatomical variation to improve your clinical skills as a health professional or biomedical scientist.

Anatomical variation is described as the differences in macroscopic morphology (shape and size), topography (location), developmental timing or frequency (number) of an anatomical structure between individuals. It presents during embryological or subadult development and results in no substantive observable interruption to physiological function. Every organ displays an array of anatomical phenotypes, and for these reasons the anatomy of each person is considered a variant. Understanding anatomical variation is essential for all health professionals to avoid patient misdiagnosis such as confusing a natural variant with a pathology, minimise surgical or procedural errors that may occur if variations are unexpected, and ultimately improve patient outcomes by applying culturally safe practices.

Anatomical variation of Aboriginal, Torres Strait Islander and Māori peoples has also been highlighted where research is available.

The textbook is organised to complement your health science studies by developing your depth of understanding to address three critical themes in anatomical variation: Theme 1: Categorise and describe a range of anatomical variation within the human body. Theme 2: Theorise the implications of anatomical variation on patient outcomes and in professional contexts. Theme 3: Investigate the process of anatomical variation formation and its potential causes.

Each chapter employs a multimodal and active learning approach using text and video summaries of key information, checkpoint quizzes, interactive images, clinical and professional discussion activities, and recommended readings. In this way, the activities in this textbook can be easily embedded into existing health science curricula to strengthen anatomical variation understanding in all health professional courses.
