TERM 1 The process of deliberately simplifying a real- world situation in order to isolate the most important elements for inclusion into a model is called DEFINITION 1 Abstraction TERM 2 Linear, exponential, and oscillatory are types of DEFINITION 2 functional behavior TERM 3 A structural feature of a model that reinforces whatever behavior the model is producing is a DEFINITION 3 positive feedback loop TERM 4 If not for the delay caused by the pipes, the output temperature in the shower model would be a simple linear combination of the inputs, called a DEFINITION 4 weighted average TERM 5 Phrenology is presented as an example of DEFINITION 5 discredited theory TERM 6 Responses of a real-world system correspond to which component of a model? DEFINITION 6 outputs TERM 7 A setting for a model that remains constant during a model run is a(n) DEFINITION 7 parameter TERM 8 A number that changes during a model run, and whose value is calculated by the rules of the model, is a(n) DEFINITION 8 dependent variable TERM 9 A structural feature of a model that dimishes whatever behavior the model is producing is a DEFINITION 9 negative feedback loop TERM 10 A run of the model with a single set of inputs, parameters, and outputs is called a DEFINITION 10 simulation TERM 21 This type of model is made up of specifically defined components and rules, expressed in terms of numbers and equations DEFINITION 21 Formal Model TERM 22 This type of model is most suitable for implementing on a computer: DEFINITION 22 Formal Model TERM 23 Yeast is a fungus and reproduces asexually by budding, resulting in a growth rate that is very similar to bacterial growth (bacteria reproduce asexually by fission). In the presence of enough food supply, the growth of the yeast population is __________. DEFINITION 23 Exponential TERM 24 the process of estimating a function value in between two known values DEFINITION 24 interpolation TERM 25 a computational (numerical) method which can be used to find an approximate solution for the logistic differential equation DEFINITION 25 euler's method TERM 26 In case of exponential decay, the growth rate of the exponential function is __________. DEFINITION 26 negative TERM 27 If the food supply is not resupplied during the propagation of the yeast population, in other words, the food is a nonrenewable resource, what would happen when the yeast propagate? DEFINITION 27 food decrease at accelerating rate TERM 28 Under the assumptions of finite food and fixed lifespan, how would the yeast population change over time? DEFINITION 28 increase exponentially at first, then decline to 0 TERM 29 What is the name of an equation like dN/dt = k*N, where dN/dt means the rate of change of N? DEFINITION 29 differential equation TERM 30 A system that will remain in the same state if it is not disturbed, but that will rapidly change if it is disturbed even slightly, is said to be in DEFINITION 30 unstable equilibrium TERM 31 A system that will remain in the same state if it is not disturbed, and that will return to this state if it is disturbed, is said to be in DEFINITION 31 stable equilibrium TERM 32 Input variables in a linear model are also called DEFINITION 32 independent variables TERM 33 A model that accurately predicts the behavior of a real-world system is called DEFINITION 33 valid model TERM 34 If your course grade is computed by a weighted average, DEFINITION 34 weights add up to 100% TERM 35 Which technique is used to find the linear model that best fits a collection of measured data? DEFINITION 35 regression
