4434Introduction to Software Engineering
https://www.merlot.org/merlot/viewMaterial.htm?id=1209037
Homework to provide students with a introductory understanding of the discipline of Software Engineering. Thu, 28 Jul 2016 12:44:13 -0700Desktop applications: Microsoft Access 2010 intermediate day 2
https://www.merlot.org/merlot/viewMaterial.htm?id=1208936
This illustrated training guide follows on from Desktop applications: Access 2010 Intermediate day 1. It is a step-by-step reference guide to some advanced features of Microsoft Access 2010. This guide is a companion to the Access 2010 Intermediate Day 2 course. The guide includes some advanced ways of using forms to control data entry and ensuring the integrity of the data entered into the tables. The use of macros to automate tasks in Microsoft Access 2010 will be introduced. This guide will also examine some of the advanced properties of reports.The training guide is provided by the IT Services Training team at The University of Manchester, England.Thu, 28 Jul 2016 08:19:56 -0700Solar and Lunar Eclipse Model
https://www.merlot.org/merlot/viewMaterial.htm?id=1207205
The Solar and Lunar Eclipse model simulates the occurrences of solar and lunar eclipses. Moon's orbital inclination of 5.145 degrees with respect to the ecliptic (the Earth-Sun orbital plane) is what is responsible for solar and lunar eclipses not occurring every month. In addition, the orbital plane of Moon precesses every 8.85 years, the so-called precession of the apsides. The inclination and the motion of Moon and Earth are depicted (the size of Sun, Earth, and Moon and the size of Moon's orbit are not shown to scale). The illuminated sides of Earth and Moon and the regions of possible eclipses (in yellow and green) are also depicted. In the Ecliptic View, the motion of Sun and Moon across the sky (+/- 7 degrees from the ecliptic) are shown. Moon's phase is shown and solar and lunar eclipses can occur on the ecliptic when Earth, Sun, and Moon line up properly.Wed, 27 Jul 2016 19:55:47 -0700Exoplanet Detection: Radial Velocity Method
https://www.merlot.org/merlot/viewMaterial.htm?id=1207203
The Exoplanet Detection: The Radial Velocity Method model simulates the detection of exoplanets by using the radial velocity method and the Doppler effect. In this simulation the exoplanet orbits the star (sun-sized) in circular motion via Kepler's third law. The radial velocity of the star is determined from the velocity of the exoplanet. This velocity is then used to calculate the Doppler shift of the Fraunhofer lines of the star. In practice it is the Doppler shift of the Fraunhofer lines of the star that are detected and from this the radial velocity is inferred. From this the mass and orbital period and average exoplanet-star separation are determined. In the simulation the star-exoplanet system is shown as seen from Earth (edge on view) and from space (overhead view), and with the star and exoplanet sizes not shown to the scale of the orbit. In addition, the Fraunhofer lines are shown. The radial velocites of stars are such that the Doppler shifts are small, to compensate you may snap to the Na line and use the right-hand side slider to zoom in on that line to see wavelength shift. The mass of the exoplanet (relative to the mass of Jupiter), the average star-exoplant separation (in AU), and the inclination of the system relative to Earth can be changed. The simulation uses Java 3D, if installed, to render the view the star and exoplanet. If Java 3D is not installed, the simulation will default to simple 3D using Java.Wed, 27 Jul 2016 19:55:42 -0700GalaxSee HPC II: Scaling N-Body Simulations
https://www.merlot.org/merlot/viewMaterial.htm?id=1207201
This teaching module continues with a demonstration of parallel and high-performance computing applied to the simulation of n-body system with a consideration of the issues that arise and approaches that are used to scale the such simulations. An initial introduction into GalaxSee HPC is covered in part I of the GalaxSee HPC modules. Part II will focus on numerical issues related to solving the N-Body problem more efficiently, in particular the use of softened potentials in the force calculation, the use of tree-based methods such as the Barnes-Hut method, and the use of spectral methods such as the Particle-Mesh method. Some of the mathematics involved can be performed by a student with a solid basis in algebra; however the theory behind the Particle-Mesh method does assume some knowledge of partial differential equations and of the use of Fourier transforms to simplify the solution of PDEs with periodic boundary conditions.Wed, 27 Jul 2016 19:55:40 -0700QuarkNet

Practice finding elapsed time given a starting time and an ending time. Elapsed Time is one of the Interactivate assessment explorers.Wed, 27 Jul 2016 19:55:32 -0700Number Base Clocks
https://www.merlot.org/merlot/viewMaterial.htm?id=1207195
Visually explore counting and place value with different number bases, from base 2 to base 16, and up to the hundreds place using a clock like interface. The activity also allows you to look at the numbers on the clock in base 10 or in your other chosen base to explore the relationship between those values.Wed, 27 Jul 2016 19:55:28 -0700
