- trauma
- A body wound or shock produced by sudden physcial injury (physical or mental)
- Regression analysis
- Modeling and analysis of numerical data consisting of values of a dependent variable (response variable) and of one or more independent variables (explanatory variables).
- mastication
- the act of chewing : as of food
- Rhytidectomy
- plastic surgery to remove wrinkles and other signs of aging from your face
- pyramid (geometry)
- it is a conic solid with polygonal base
- parametric surface
- E.g. Bivariate parametric surface - Defined by 3 functions of 2 parametric variables, one function for each spatial dimensions. These surfaces are defined in terms of control values (3D points which are near) and basis functions.
- prosthesis
- A device either eternal or implanted that substitiutes for or supplements a missing or defective part of the body
- Pathology
- The study and diagnosis of diseases throught the examination of organs, tissues, bodily fluids and whole bodies.
- prism
- 2 p-gons and p parallelograms as faces, e.g. hexagonal prism - 2 hexagons connected by 5 parallelograms
- cadaver
- a dead body
- Ultrastructure
- The detailed structure of a biological specimen that can be observed by a ELECTRON microscope
- polygon
- A plane figure that is bounded by a closed path or circuit, E.g. triangle, quadrilateral
- Constitutive Equation
- A relation between two physical quantities (often described by tensors) that is specific to a material or substance and does not follow directly from physical law
- Nonlinear regression
- It fits data to any equation that defines Y as a function of X and one or more parameters. The aim is to minimize the sum of the squares of the vertical distances between data points and curve. This requires a intensive iterative approach
- Osteology
- The branch of anatomy dealing with the skeleton. Study of the structural bone, skeletal elements, teeth, morphology, function, disease, pathology. Often used by scientists with identification of human remains with regard to age, death, sex, growth, and development in a biocultural context.
- Stereology (stereo - solidity, three dimensionality)
- A branch of science dealing with the determination of the three-dimenaional structure of objects based on 2D views of them
- Musculature
- The muscular system of an animal, or of any of its parts
- Orthopedics (Ortho- 'correct')
- The branch of surgery concerned with the correction or prevention of injuries or disorders of the skeletal system and the associated muscles, joints and ligaments.
- Neo-Hookean
- - Special case of Mooney-Rivlin (if C1 = 0.5G, C2 = 0), - Strain energy is proportional to the first invariant of Finger tensor and the shear modulus (ratio of shear stress over shear strain)
- excision
- removal of skin lesion (any morbid change in the exercise of functions or the texture of organs) by completely cutting it off
- Rheology.
- The study of deformation and flow of matter under applied stress.
- flap
- tissues taken from one part to another part of the body (e.g. skin, fascia, muscle, bone) with an intact blood supply
- quadrilateral
- a polygon with four sides or edges and four vertices or corners
- Morphology
- refers to the outward appearance (shape, structure, colour, pattern) of an organism or taxon and its component parts. This is in contrast to physiology, which deals primarily with function.
- Lagrange polynomials
- is the interpolation polynomial for a given set of data points in the Lagrange form
- implicit surface
- Defined by a function F(x, y, z) that assigns a scalar value to each point in x, y, z space.
- interpolation polynomial in the Hermite form
- The coefficients of the polynomial are calculated using divided differences, that considers given derivatives at data points, as well as the data points themselves. The interpolation will give a polynomial that has a degree less than or equal to the number of both data points and their derivatives, minus 1.
- Topology
- The study of those properties of geometric forms that remain invariant under certain transformations e.g. bending without shearing
- axiom
- Universally accepted principle
- flex (the polygon must be laid out in a way that allows the face to flex)
- to bend
- Histology
- The study of (microscopic anatomy) tissues. Performed by examination a thin slice of tissues under a light telescope.
- Physiology
- The study of biomechanical, physical and mechanical functions of living organisms
- Mooney-Rivlin
- W = C1(I1 - 3) + C2(I2 - 3) + 1/d (J - 1)^2, -Nonlinear relationship between stress and strain (Elastic modulus of the material increases after a certain point)
- impetus (The grant for building the opera house gave impetus to the city's cultural life), (The approaching deadline gave impetus to the investigation)
- A moving force; impulse; stimulus
