Honours dissertation in Electrical Engineering "Interactive Computer Package Demonstrating: Sampling Convolution and the FFT", Adrienne Gaye Thompson, University of Aberdeen (1983). The package computes the linear convolution of two signals in the time domain then compares their circular convolution by demonstrating the convolution theorem. Each signal is modelled by a register of discrete values simulating samples of a signal, and the discrete Fourier transform (DFT) computed by means of the Fast Fourier Transform (FFT). GNU C-Graph is interactive, prompting the user to enter character or numerical values from the keyboard, dispensing with the learning curve for writing code. The software will be useful to students of signals and systems theory. C-Graph is written in contemporary Fortran. You can find pre-GNU development versions at: Code Art Now. Adrienne Gaye Thompson is the sole author of GNU C-Graph and looks forward to sharing further development with the Free software community.

CT Sim: Computed Tomography is the technique of estimating the interior of objects from the measurements of radiation projected through the object. That radiation can be transmitted through the object such as in X-ray computed tomography or emitted from internal radiation sources as in nuclear medicine scans. CTSim simulates the transmission of X-rays through phantom objects. These X-ray data are called projections; CTSim reconstructs the original phantom image from the projections using a variety of algorithms. The program also has a wide array of image analysis and image processing functions.

CVAssistant: Whether you're looking for a job or trying to help a friend to find one, CVAssistant is the number one tool for you. It helps you by preparing resumes and cover letters and organizing your job application process. It: Stores all your skills and experiences. Creates resumes tailored for each job you apply. Creates cover letters summarized to match each job advertisement. Keeps a history of job applications so you are ready when you receive a phone call. Write resumes in your language. All languages are supported! It's a free and open source software which you can easily download to your computer and start using it out of the box. CV Assistant helps you create specialized resumes in Word .docx format fast and easy. The idea is to have a master resume with all skills and experiences in it. Then based on skills mentioned in the job advertisement, export a clean but well formatted word .docx file as a summarized resume with only relevant skills in it. This increases your chance of getting a job interview as most companies are using Applicant Tracking Software (ATS) or at best hiring managers which may be unaware of similarity between phrases like skilled in MS Word, familiar with Microsoft Word and Fully experienced with office suites. So job seekers need to create specialized resumes for each and every job position with the same wordings used in the advertisement. Add all your skills to CV Assistant, pick only relevant ones. It also creates cover letters! Again, write all possible sentences, and select those relevant ones per job post. CVAssistant helps you free of charge and this software remains for free!

CVSSearch: CVSSearch searches for code fragments using CVS comments. Since a CVS comment describes the lines of code involved in the commit and that this description will typically hold for many future versions. CVSSearch lets you to better search and understand the most recent version of the code by looking at previous versions. For each line of code in the most recent version, we build a profile consisting of all CVS comments that involved that line in past commits. This profile is used not only to search the most recent version of the code but also to understand what the code does --- including its motivation and history.

Celestia: Celestia is a real-time visual simulation of space. Choose a point within the Local Group of galaxies, and Celestia will show you an approximation of how it would appear to your eyes were you actually there. Some of what Celestia shows is necessarily hypothetical--the farther away from Earth you get, the less real data there is and the more guesswork is involved. Thus Celestia supplements observational data with good guesses based on models of stellar and planetary processes. You can also navigate at an immense range of scales. Orbit a couple kilometers above the surface of a tiny, irregular asteroid, then head off toward Jupiter, watching it grow from a bright point of light into a looming sphere filling your field of vision. Leave our solar system entirely and observe the sun as it fades from a brilliant disk to a bright star, disappearing almost entirely as you head off toward the Upsilon Andromeda system to orbit around its innermost giant planet.
