Physics Lab Line Straightening and Graphing in a Spreadsheet Using data from a Coulomb Torsion Balance experiment, I show how to use a spreadsheet to first linearize the data, then graph it. This includes putting in a trendline (line of best fit) and a formula representing the trendline. I am using Calc as my spreadsheet program. Oh, and yes, I know I put in the wrong units for the x axis on the graph. Should be (m^-2).
Linear Vs. Exponential Functions This video gives an example of a linear function and an example of an exponential function. I discuss the differences between the two functions in terms of their rates of change. Please forgive the mistake at approx. 4:26 where I state the y-intercept as being at 100 rather than 105.

Logarithmic Suck Factor.MP4 This is an improvement on the Relative Suck Factor. Here's an example of how logarithms can be used to linearize a scale. Relative Suck Factor (RSF) started as a joke by people who were comparing the undesirability of two possible choices. RSF is fine, but it is highly non-linear. Using logarithms to form the Logarithmic Suck Factor (LSF) solves the problem
Modeling Lecture 18: Introduction to RTDs - Quantum Charge Self-Consistency (Hartree) - Part 1/2 The previous lectures showed that a semi-classical charge distribution results in a vast improvement in the realism of the electrostatic potential over a linear potential drop approximation. In this semi-classical charge and potential model the quantum mechanical simulation is performed once and the quantum mechanical charge is in general not identical to the semi-classical charge. In the high doping contacts that is a reasonable assumption, however close to heterointerfaces the quantum mechanical nature of the carriers reflects itself in the charge profile significantly and a semi-classical charge profile is not necessarily the best approximation. Simple quantum charge-selfconsistent potential (Hartree) calculations feed the quantum charge into the potential calculation and iterate until the two do not change anymore from one iteration step to the next. The quantum mechanical charge calculations predict a charge accumulation inside the central RTD which increases the charge inbalance in the undoped region, which in turn forces the electrostatic potential to resist that charge inbalance. The resonances therefore do not get pulled down in voltage linearly anymore. The charge & potential interactions introduce a non-linear device behavior which stretches out the voltage axis, linearizes the IV curve, and increases the peak current. Learning Objectives: Semi-classical charge and quantum charge differ significantly at the interfaces and inside the RTD. The electrostatic ...

Regression ***ysis vs Newton's Law of Cooling Nonlinear Least Squares Regression - CurveFitter is developed to help the children suffering from cancer in the "Save-the-Children" charity project of Children's Hospital in Finland. CurveFitter is a powerful statistical ***ysis program that performs linear and nonlinear regression ***ysis (ie curve fitting). CurveFitter determines the values of parameters for an equation, whose form you specify, that cause the equation to best fit a set of data values. CurveFitter can handle linear, polynomial, exponential, and general nonlinear functions. Unlike many "nonlinear" regression programs that can only handle a limited set of function forms, CurveFitter can handle essentially any function whose form you can specify algebraically. CurveFitter performs true nonlinear regression ***ysis, it does not transform the function into a linear form. As a result, it can handle functions that are impossible to linearize such as ("Newton's Law of Cooling"): y = (a - c) * exp(-b * x) + c Another advantage of handing the function in true nonlinear form is that the minimization of the sum of squared residual values (ie, "least squares") is based on the true nonlinear value rather than some linearized transformation. In addition to computing the optimal values of the parameters to best fit the function to the data, CurveFitter generates plots of the data points and the fitted equation. In addition, it plots the distribution of residual values. This state-of-the-art data fitting includes the ...

Pendubot A pendubot is simply a double pendulum, with one end connected to a motor, and an encoder attached at the elbow. Here I demonstrate that in an un-powered state, the pendubot acts as a double pendulum, and will swing in seemingly chaos when released. Once powered, the pendubot can receive a set of poles, which can be derived from the linearization of the system dynamics around the equilibrium points. Here I am linearizing the pendubot so it will swing into, and self balance in an up-up position. Check out my other videos, where I linearize it to a down-up position.
Life Mask Portraiture - Receptionists.m4v This body of work expands upon my first 'Life Mask Portrait' pieces, making use of my home-made 20x16 camera to produce life size documents of University Receptionists. The concept here, is to make abstract recordings that question the way we perceive individuals who provide us with information. Such positions entail brief encounters with many individuals, each of whom will formulate a mental effigy of their encountered desk staff. Faces are but palates that we apply the paint, flesh for which we wear the masks. The nature of our culture, in its embellishment of semiotic structuring, enhances such delusions of objectivity. As presented here, my approach has incorporated two types of portrait images. One is my 20x16 paper negative 'Life Mask Portraits'. These abstract, fine detailed documents, through the lateral and tonal reversal, subvert the visuality if our daily perception. The level of detail that is otherwise passively un-acknowledged is, through the scale of the negative and the optics, illuminated for all to see. Such nuances are of little concern to us, as are the nuances of social realities (injustice). Secondly, I incorporate a life-size positive image (produced on transparency film), which I call 'Emotion Portraits'. These focus on documenting posed emotions, which I collaborate with my sitters to produce. Such insincerity, and often the obviousness of it, is something I have sought to explore. My intention here is to play with the idea of subjectivity in ...

Detection of Functional Matrix Metalloproteinases by Zymography Watch video protocols on JoVE - . Journal of Visualized Experiments (JoVE) is a scientific journal publishing video articles on biological experiments filmed at leading research institutions. JoVE is the first video journal indexed in PubMed. To see more of this protocol go to Detection of Functional Matrix Metalloproteinases by Zymography This video protocol was filmed at Baylor College of Medicine. Matrix metalloproteinases (MMPs) are zinc-containing endopeptidases. They degrade proteins by cleavage of peptide bonds. More than twenty MMPs have been identified and are separated into six groups based on their structure and substrate specificity (collagenases, gelatinases, membrane type [MT-MMP], stromelysins, matrilysins, and others). MMPs play a critical role in cell invasion, cartilage degradation, tissue remodeling, wound healing, and embryogenesis. They therefore participate in both normal processes and in the pathogenesis of many diseases, such as rheumatoid arthritis, cancer, or chronic obstructive pulmonary disease1-6. Here, we will focus on MMP-2 (gelatinase A, type IV collagenase), a widely expressed MMP. We will demonstrate how to detect MMP-2 in cell culture supernatants by zymography, a commonly used, simple, and yet very sensitive technique first described in 1980 by C. Heussen and EB Dowdle7-10. This technique is semi-quantitative, it can therefore be used to determine MMP levels in test samples when known concentrations of ...
