Investigate Experian

This m-file is used in experiments involving several factors where it is necessary to investigate the joint effects (main and interactions) of the factors on a response variable and determine by a formal analysis of variance which factor effects are nonzero. Each of the three factors (k = 3) of...

Say you are only able to obtain a limited number of terms in a power series, as each term is increasingly difficult to obtain (ex. virial equation of state). To explore possible analytic continuations, you need an infinite series representation. A rational function is one way to prescribe this,...

The program helps to investigate cell dynamics in fluorescent images that can be tracked using the spot track function in Imaris. I used Imaris 5.0.3 to generate the spot positions.Reads in spot positions in the excel output from Imaris image processing software and measures track lengths,...

KNIME, pronounced [naim], is a modular data exploration platform that enables the user to visually create data flows (often referred to as pipelines), selectively execute some or all analysis steps, and later investigate the results through interactive views on data and models.

NetEvo is a computing framework and collection of end-user tools designed to allow researchers to investigate evolutionary aspects of dynamical complex networks. By providing tools to easily integrate each of these factors in a coherent way, it is hoped a greater understanding can be gained of...

This script will create a column subset from a numeric spreadsheet, then take the row averages and create a histogram of those averages. You can specify the subset by column number or by marker (if the spreadsheet has a marker map). This is useful for LogR spreadsheets to investigate for possible...

Constraint satisfaction problems (CSPs) are pervasive in AI problems. A constraint satisfaction problem is the problem of assigning values to variables that satisfy some constraints. This tool lets you investigate arc consistency and domain splitting with backtracking as ways to solve these...

This simulation gives students a powerful way to investigate the meaning of shape and slope for three types of motion graphs: position vs. time, velocity vs. time, and acceleration vs. time. The simulation starts with a motion diagram of a blue ball moving horizontally, with a position vs. time...

Taxonnerator is a software package for carrying out simple similarity-based annotation of clustered barcode sequence data produced by jMOTU. It generates taxonomic annotation for MOTU by BLASTing representative sequences against a preformatted database of sequences from known organisms (available...

A capacitor is a device for storing charge. In this simulation, you can investigate a relatively simple capacitor, known as a parallel-plate capacitor. It consists of two identical metal plates, placed parallel to one another. The capacitor can be charged by connecting one plate to the positive...

The Driven Mass and Spring Mesh model displays the dynamics of a 2D array of masses coupled by springs and driven by a sinusoidal force. The model shows a time-dependent animation of the displacement or each mass. The driving force can be applied at a single point (shown in red) or uniformly at...

A velocity selector is a region in which there is a uniform electric field and a uniform magnetic field. The fields are perpendicular to one another, and perpendicular to the initial velocity of the charged particles that are passing through the region. The force exerted on a charged particle by...

The Light and Shadow Model shows light that either passes through a mask with a hole in it, or it is blocked by an object, as it travels to a screen on the right. The user can turn on and off two light bulbs (red and blue) and drag the bulbs around the screen to change their positions....

This interactive simulation allows students to collide two objects and investigate whether momentum and/or kinetic energy are conserved in the collision process. To keep things simple, the simulation involves an isolated system where the objects collide along a single line. Use the sliders to set...

Are you ready to investigate a haunting? The Peter Wren Paranormal Investigative Agency is working on a new case at Kotsmine Hills in Virginia, a lonely mining town that been the site of a terrible disaster in 1929. You see, a snowstorm swept through the area, blanketing the town and cutting it...
