Computing Open Education Resources

In previous posts the availability on the JISC Jorum repository of three Open Education Resources (OERs) from the Computing Team at the University of Northampton was discussed. After 13 years the Jorum repository was discontinued.

Two of the OERs though were migrated across to the JISC Apps and resource store and available for reuse.

1. C Programming

Now available at https://store.jisc.ac.uk/#/resource/8395 and download from https://store.jisc.ac.uk/download/8395


















2. Summary of Evolutionary Algorithms

Now available at https://store.jisc.ac.uk/#/resource/8405 and download at https://store.jisc.ac.uk/download/8405

What do we do ? - bibliographic analysis

In an earlier post looked at the interconnections since 2011 of members of the Computing team at the University of Northampton, as viewed through data available in the University's Research Repository.

In the following images the most commonly (appears at least 3 times in either the title or abstract of papers) words are displayed. The data was processed using the VosViewer from the Centre for Science and Technology Studies, Leiden University, The Netherlands.

The image above is for the whole of the Computing publications listed and suggests since 2011 an emphasis on education, networking and modelling; with some 'islands' around data analysis; system design; network on a chip and interestingly 'clinical symptom' (which is probably related to some work with data analysis of animal health).


The two images below are taken from individual's team memeber's data within the repository. The criteria for inclusion was words that had appeared three or more times in either the title or the abstract - a word was only counted once per paper.

The one above covers data for one person; and seems to include areas around robots and problem-solving; modeling of systems.

This one seems to have groupings around smart cities; development of technology processes; simulation; and vehicle-to-vehicle communications.

Author: Dr Scott Turner
In this material you will be introduced to some of the principles of programming, and specifically learn to write fairly simple programs using a programming language called C. An idea central to this material is that programming is about problem solving; you write a program to solve a particular problem. It is hoped that at the end of the material you should see that there is nothing magical or mysterious about programming. One of the features some people like about programming is you are making the computer do what you want. During the programming exercises, do not worry about making mistakes. In this material you will be expected to try out programs and eventually write your own. The target audience is anyone who wants to learn a programming language or is looking for some assessment questions around programming. The material was originally aimed at second year engineering students at the University of Northampton.

evolutionary algorithms to select filters for evoked potential enhancement+ references

Use of evolutionary algorithms to select filters for evoked potential enhancement

Abstract
Evoked potentials are electrical signals produced by the nervous system in response to a stimulus. In general these signals are noisy with a low signal to noise ratio. The aim was to investigate ways of extracting the evoked response within an evoked potential recording, achieving a similar signal to noise ratio as conventional averaging but with less repetitions per average. In this thesis, evolutionary algorithms were used in three ways to extract the evoked potentials from a noisy background. First, evolutionary algorithms selected the cut-off frequencies for a set of filters. A different filter or filter bank was produced for each data set. The noisy signal was passed through each filter in a bank of filters the filter bank output was a weighted sum of the individual filter outputs. The goal was to use three filters ideally one for each of the three regions (early, middle and late components), but the use of five filters was also investigated. Each signal was split into two time domains: the first 30ms of the signal and the region 30 to 400ms. Filter banks were then developed for these regions separately. Secondly, instead of using a single set of filters applied to the whole signal, different filters (or combinations of filters) were applied at different times. Evolutionary algorithms are used to select the duration of each filter, as well as the frequency parameters and weightings of the filters. Three filtering approaches were investigated. Finally, wavelets in conjunction with an evolutionary algorithm were used to select particular wavelets and wavelet parameters. A comparison of these methods with optimal filtering methods and averaging was made. Averages of 10 signals were found suitable, and time-varying techniques were found to perform better than applying one filter to the whole signal.
