3D printing or additive manufacturing is a novel method of manufacturing parts directly from a digital model by using layer by layer material build-up approaches. This discovery is predicted to have the greatest impact on the future industries. Additive manufacturing has numerous applications in different areas including healthcare. Applications encompass many medical fields such as dentistry, surgery, and medical devices as well as the pharmaceutical field. Due to transplant donor deficiencies, ‘bioprinting’ has been invented to print biocompatible organs. Adding ‘time’ as a 4th dimension, 4D printing uses ‘smart materials’ to initiate the ‘smart drugs’ era.

This paper presents a method for classification of medical images, using machine learning and deformation-based morphometry. A morphological representation of the anatomy of interest is first obtained using highdimensional template warping, from which regions that display strong correlations between morphological measurements and the classification (clinical) variable are extracted using a watershed segmentation, taking into account the regional smoothness of the correlation map which is estimated by a crossvalidation strategy in order to achieve robustness to outliers. A Support Vector Machine-Recursive Feature Elimination (SVM-RFE) technique is then used to rank computed features from the extracted regions, according to their effect on the leave-one-out error bound. Finally, SVM classification is applied using the best set of features, and it is tested using leave-one-out. The results from a group of 61 brain images of female normal controls and schizophrenia patients demonstrate not only high classification accuracy (91.8%) and steep ROC curves, but also exceptional stability with respect to the number of selected features and the SVM kernel size
Medical data processing and analysis
Medical data can be defined as obtaining information from patients (such as signals, images, sounds, chemical components and their concentration, body temperature, respiratory rate, blood pressure, and different treatment measurements) to quantify the patient’s status and disease stage. Computer-aided diagnostic (CAD) systems use classical image processing, computer vision, machine learning, and deep learning methods for image analysis. Using image classification or segmentation algorithms, they find a region of interest (ROI) pointing to a specific location within the given image or an outcome of interest in the form of a label pointing to a diagnosis or prognosis. Computer science, with the evolution of artificial intelligence and machine learning techniques, facilitates the modeling and interpretation of results—from carrying out measurements to experiments and observations.
Medical centers management system
The medical clinics management system (MCMS) is a system that manages a group of clinics distributed within different governorates and regions in Syria, as it manages data entry processes for each patient such as personal information, disease and accompanying symptoms in addition to doctors' information, and clinics through a web application. The system also performs mining algorithms on the current data for discovering new symptoms and diseases by analyzing patient, diseases and symptoms data available within the database, to subsequently notify the admins of the emergence of a new symptom or an increase in a disease in a given area. In addition to generating daily or weekly reports containing the number of visits and cases of recovery and other information.
Mechanosensing and Mechanochemical Transduction in Extracellular Matrix : Biological, Chemical, Engineering, and Physiological Aspects
Mechanosensing and Mechanochemical Transduction in Extracellular Matrix offers the reader recent information in addition to models of how mechanical information is transduced into genetic and biochemical changes at the cellular and tissue levels. Mechanosensing and Mechanochemical Transduction in Extracellular Matrix is intended to serve as a textbook at the graduate and advanced undergraduate level in a biomedical engineering curriculum.
Mechanisms of mineralization of vertebrate skeletal and dental tissues
Presents a multi-disciplinary approach to understanding mechanisms regulating the formation of mineral in vertebrate skeletal and dental tissues. The focus of the book is directed toward the mineralization process, an evolutionarily conserved system in which cells synthesize a complex and unique extracellular matrix into which mineral is deposited. Regulatory control is viewed though lenses that emphasize the genetic, physical-chemical, biochemical, structural, cellular and extracellular aspects of the mineralization process as they relate to crystal nucleation, growth and maturation. Throughout the book, defects in regulation at the genetic and transcriptional levels are linked to the numerous clinical problems associated with the mineralization of bone, cartilage, tendon, tooth, and soft tissues.
Mechanisms of Angiogenesis
Is it advisable to go back from bedside to the bench? During the last decade, few topics encountered such a broad interest in bio- gy and medicine as angiogenesis. The amazing ability of the body to restore blood flow by induction of blood vessel growth as part of an adaptive process has alarmed physicians dealing with diseases in which angiogenesis is either exaggerated (as in tumors) or too slow (as in ischemic diseases of heart and brain). Not surprisingly, pro- and antiangiogenic strategies have found their way into clinical trials. For instance, for the USA, the NIH website in early 2004 displayed 38 clinical studies involving either pro- or antiangiogenic th- apies. Given the expected overwhelming wealth of clinical data, the question may be asked whether further exploration of biological mechanisms is required or whether results from the bedside are instructive enough to proceed. This question depends also on the progress of pro- and antiangiogenic clinical trials. In the following, I give a short overview about some of the progress that has been made in this field. Since Judah Folkman proposed antiangiogenic tumor therapy thirty years ago, it has become increasingly evident that agents which interfere with blood vessel formation also block tumor progression. Accordingly, antiangiogenic therapy has gained much attention as a potential adjunct to conventional c- cer therapy.
Mechanics of Microelectronics
Written by the leading experts with both profound knowledge and rich practical experience in advanced mechanics and microelectronics industry, this book aims to provide the cutting edge knowledge and solutions for various mechanical related problems, in a systematic way. It contains essential and detailed information about the state-of-the-art theories, methodologies, the way of working and real case studies.
Mechanics of Material Forces
The book covers both theoretical and numerical developments. Conceptually speaking, common continuum mechanics in the sense of Newton—which gives rise to the notion of spatial (mechanical) forces—considers the response to variations of spatial placements of "physical particles” with respect to the ambient space, whereas continuum mechanics in the sense of Eshelby—which gives rise to the notion of material (configurational) forces—is concerned with the response to variations of material placements of "physical particles” with respect to the ambient material. Well-known examples of material forces are driving forces on defects like the Peach-Koehler forece, the J-Integral in fracture mechanics, and energy release. The consideration of material forces goes back to the works of Eshelby, who investigated forces on defects; therefore this area of continuum mechanics is sometimes denoted Eshelbian mechanics.
Mechanics of biomaterials : Fundamental principles for implant design
Teaching mechanical and structural biomaterials concepts for successful medical implant design, this self-contained text provides a complete grounding for students and newcomers to the field. Split into three sections: Materials, Mechanics and Case Studies, it begins with a review of sterilization, biocompatibility and foreign body response before presenting the fundamental structures of synthetic biomaterials and natural tissues. Mechanical behavior of materials is then discussed in depth, covering elastic deformation, viscoelasticity and time-dependent behavior, multiaxial loading and complex stress states, yielding and failure theories, and fracture mechanics. The final section on clinical aspects of medical devices provides crucial information on FDA regulatory issues.
Mechanics and Physics of Fracture : Multiscale Modeling of the Failure Behavior of Solids
Provides a comprehensive understanding of the macroscopic failure behavior of solids from the description of the microscopic failure processes and their coupling with the microstructure. Several fundamental questions were addressed: the relation between the microstructural features of materials and their fracture properties and crack trajectories; the role of damage mechanisms and non-linear deformations near the crack tip on the failure behavior of solids; and finally the role of dynamic inertial effects during fast fracture was more briefly evoked.
Mechanical Response of Composites
This book contains twelve selected papers presented at the ECCOMAS Thematic Conference — Mechanical Response of Composites, and the papers presented by the three plenary speakers. It describes recent advances in the field of analysis models for the mechanical response of advanced composite materials, ranging from the simulation of the manufacturing process to the inelastic response and collapse of the material. The analysis models are based on recent advances in computational mechanics such as multi-scale modeling, cohesive and partition of unity models.
Mechanical Behaviour of Engineering Materials : Metals, Ceramics, Polymers, and Composites
How do engineering materials deform when bearing mechanical loads? To answer this crucial question, the book bridges the gap between continuum mechanics and materials science. The different kinds of material deformation (elasticity, plasticity, fracture, creep, fatigue) are explained in detail. The book also discusses the physical processes occurring during the deformation of all classes of engineering materials (metals, ceramics, polymers, and composites) and shows how these materials can be strengthened to meet the design requirements. It provides the knowledge needed in selecting the appropriate engineering material for a certain design problem. The reader will thus learn how to critically employ design rules and thus to avoid failure of mechanical components.
Measuring the Business Value of Cloud Computing
The importance of demonstrating the value achieved from IT investments is long established in the Computer Science (CS) and Information Systems (IS) literature. However, emerging technologies such as the ever-changing complex area of cloud computing present new challenges and opportunities for demonstrating how IT investments lead to business value.
Measuring Methane Production from Ruminants
The world’s livestock sector is amidst a major transformation, fuelled by high demand for meat and milk, which is likely to double over the next two decades in developing countries. The challenge is to enhance animal productivity without adversely affecting the environment. A key to this is reducing methane emissions from ruminants. The major limitation to ruminant production in many tropical regions of Africa, Asia and Latin America, where a large proportion of the global ruminant population is located, is poor nutrition. The productivity of animals is restricted by the low nitrogen and high fibre content of the native grasses and crop residues, which form the basis of the diets in these regions. Animals on these types of diets emit more methane than animals fed better quality temperate forages. These methane emissions represent a loss of digestible energy to the animal (up to 15%) as well as a threat to the environment.The challenge is to devise nutritional strategies and identify dietary components, particularly from locally available plant resources, that reduce methane emissions.
