This guide takes the reader through the 3D Printing for Repair (3DP4R) process. It consists of guidelines and tools to create a 3D printable version of spare parts needed for a product repair. 3D printing a spare part is more than just printing the original part. Instead, it is an iterative process in which the part is analysed, redesigned, manufactured, and tested, in order to come to a final part. This guide will describe these four phases in detail. The guide is meant for anybody who is interested in trying to manufacture spare parts with 3D printing technologies, remakers, tinkerers, volunteer repairers, professional repairers, and everyone who is interested in repair initiatives.

This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis.
This eBook covers Alternating Current (AC) circuit theory as well us a brief introduction of electronics. It is
broken up into seven modules. Module 1 covers the basic theory of AC signals. Since only DC sources are used in
the first eBook, details of AC signals such as sinusoidal waveforms (or sine waves), square waves, and triangle
waves are provided. Module 2, titled AC Circuits Math Background, covers the mathematics background needed
for solving AC circuit problems. The background material in Modules 1 and 2 are combined in Module 3 to solve
circuits with AC sources that include resistors, inductors, and capacitors (RLC circuits).

An essential and practical text for both students and teachers of AC electrical circuit analysis, this text picks up where the companion DC electric circuit analysis text leaves off. Beginning with basic sinusoidal functions, ten chapters cover topics including series, parallel, and series-parallel RLC circuits. Numerous theorems and analysis techniques are examined including superposition, Thévenin's theorem, nodal and mesh analysis, maximum power transfer and more. Other important topics include AC power, resonance, Bode plots and an introduction to three-phase systems. Each chapter begins with a set of chapter objectives and includes a summary and review questions. A total of over 500 end-of-chapter exercises are included. A companion laboratory manual is available.

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.

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.

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.

Le but du présent chapitre n’est pas de réaliser une description exhaustive de l’anatomie du rachis mais bien d’en présenter les caractéristiques essentielles du point de vue du clinicien afin de pouvoir juger de la normalité ou non du bilan d’imagerie. Cette lecture doit pouvoir s’effectuer sur la base des trois examens complémentaires aujourd’hui indispensables qui sont la radiographie, le CT-scan et l’IRM.

The structure of the human body is usually considered in courses in gross anatomy. These courses typically consist of lectures by the faculty, readings in assigned textbooks and the study of photographs and illustrations in human anatomy atlases. However, as student’s progress through the curriculum and move into the more clinical or practice oriented phases, many discover that the anatomical knowledge they actually need is somewhat different from the kind they possess. What many encounter is difficulty in applying their knowledge to a clinical setting.

Applied Human Anatomy was created to better integrate material that is more often than not treated separately in contemporary health care curricula. It is hoped that through this integration students will develop a deeper and more lasting knowledge and understanding of human anatomy as they are likely to need it in the evaluation and management of patients.
