Date adjustment tools : Date rollover and Individual date adjustment

Learning Management Systems (LMSs) have become a larger part of teaching and learning in the modern world. Therefore has Moodle, a free and open source e-learning tool surfaced and gained a lot of attraction and downloads. A purpose of this study has been to develop a new local plugin in Moodle with guidelines from Magnus Eriksson and Tsedey Terefe. A purpose for this project has also been to build a plugin which has the functions Date rollover and Individual date adjustment. Mid Sweden University (Miun) stated that WebCT/Blackboard was in use before Moodle and some other LMSs and the dissatisfaction with WebCT/Blackboard was rife, however some teachers liked it. Therefore WebCT/Blackboard was abandoned and Moodle was embraced. The methods of gaining information has generally been web based sources and three interviews, likewise called user tests. Programs and other aids that have been used include but are not limited to: Google Drive, LTI Provider, Moodle, Moodle documentation, Notepad++, PHP and XAMPP. The plugin has been implemented as a local plugin. The result has shown that the coded plugin, Date adjustment tools could be improved and that it was changed. In the plugin, support for old American English dates were added and the code for using the two functions “Date rollover” and “Individual date adjustment” were rewritten to not interfere with one another. A conclusion to draw from the result is that the plugin has been improved from Terefe’s implementation, although more work can be made with the plugin Date adjustment tools.

Enhancing the numerical performance of fire field models (CMS Paper)

This paper describes two new techniques designed to enhance the performance of fire field modelling software. The two techniques are "group solvers" and automated dynamic control of the solution process, both of which are currently under development within the SMARTFIRE Computational Fluid Dynamics environment. The "group solver" is a derivation of common solver techniques used to obtain numerical solutions to the algebraic equations associated with fire field modelling. The purpose of "group solvers" is to reduce the computational overheads associated with traditional numerical solvers typically used in fire field modelling applications. In an example, discussed in this paper, the group solver is shown to provide a 37% saving in computational time compared with a traditional solver. The second technique is the automated dynamic control of the solution process, which is achieved through the use of artificial intelligence techniques. This is designed to improve the convergence capabilities of the software while further decreasing the computational overheads. The technique automatically controls solver relaxation using an integrated production rule engine with a blackboard to monitor and implement the required control changes during solution processing. Initial results for a two-dimensional fire simulation are presented that demonstrate the potential for considerable savings in simulation run-times when compared with control sets from various sources. Furthermore, the results demonstrate the potential for enhanced solution reliability due to obtaining acceptable convergence within each time step, unlike some of the comparison simulations.

Document analysis of PDF files: methods, results and implications

A strategy for document analysis is presented which uses Portable Document Format (PDF the underlying file structure for Adobe Acrobat software) as its starting point. This strategy examines the appearance and geometric position of text and image blocks distributed over an entire document. A blackboard system is used to tag the blocks as a first stage in deducing the fundamental relationships existing between them. PDF is shown to be a useful intermediate stage in the bottom-up analysis of document structure. Its information on line spacing and font usage gives important clues in bridging the semantic gap between the scanned bitmap page and its fully analysed, block-structured form. Analysis of PDF can yield not only accurate page decomposition but also sufficient document information for the later stages of structural analysis and document understanding.

Practical assessment on the run – iPads as an effective mobile and paperless tool in physical education and teaching

This paper investigates the use of iPads in the assessment of predominantly second year Bachelor of Education (Primary/Early Childhood) pre-service teachers undertaking a physical education and health unit. Within this unit, practical assessment tasks are graded by tutors in a variety of indoor and outdoor settings. The main barriers for the lecturer or tutor for effective assessment in these contexts include limited time to assess and the provision of explicit feedback for large numbers of students, complex assessment procedures, overwhelming record-keeping and assessing students without distracting from the performance being presented. The purpose of this pilot study was to investigate whether incorporating mobile technologies such as iPads to access online rubrics within the Blackboard environment would enhance and simplify the assessment process. Results from the findings indicate that using iPads to access online rubrics was successful in streamlining the assessment process because it provided pre-service teachers with immediate and explicit feedback. In addition, tutors experienced a reduction in the amount of time required for the same workload by allowing quicker forms of feedback via the iPad dictation function. These outcomes have future implications and potential for mobile paperless assessment in other disciplines such as health, environmental science and engineering.
