Quality and compressibility analysis of checkerboard-based digital halftoning algorithms
… statistical redundancies form the resulting files. Mock image file formats based on Case’s halftoning methods and the above compressions are compared to other popular image formats to assess the potential of this technology.

Forensic Reconstruction of Fragmented Variable Bitrate MP3 files
File carving is a technique used to recover data from a digital device without the help of file system metadata. The current file carvers use techniques such as using a list of header and footer values and key word searching to retrieve the information specific to a file type. These techniques tend …

Crystallographic refinement of thermal parameters using normal modes
… crystallographic functions. Furthermore, the file formats and input conventions from CCP4 are used so that our program can be easily integrated into a crystallographer's toolset. The software package was tested on two systems, formiminotransferase cyclodeaminase (FTCD) and the KcsA potassium …

Design, Analysis and Fabrication of Complex Structures using Voxel-based modeling for Additive Manufacturing
… representation (e.g., the STL and the AMF file formats); which do not contain any volumetric information and often, designing/slicing/printing complex geometries exceeds the computational power available to the designer and the AM system itself. To enable efficient design and fabrication of …

Investigation of the effects of image compression on the geometric quality of digital protogrammetric imagery
… at hand. Recently, many fast and efficient image file formats have also been developed to store, organise and display images in an efficient way. Almost every image file format incorporates some kind of compression method to manage data within common place networks and storage devices. The current …

Reassembly and clustering bifragmented intertwined jpeg images using genetic algorithm and extreme learning machine
File carving tools are essential element of digital forensic investigation for recovering evidence data from computer disk drives. Today, JPEG image files are popular file formats that have less structured contents which make its carving possible in the absence of any file system metadata. However, …

Cartographic visualization of Saskatchewan’s population using dasymetric mapping.
… on the results of regression analysis. Different file formats (raster and vector) were considered when producing the dasymetric maps. It was observed that, due to the regular sizes of raster cells, dasymetric maps using raster data are generally more accurate than dasymetric maps using vector …

Digital preservation in institutional repositories in Namibian academic libraries: A case study of the Namibia University of Science and Technology (NUST) and the University of Namibia (UNAM)
… upgrades and maintenance as well as using open file formats i.e. PDF are the main techniques used at NUST and UNAM. The study also discovered a significant lack of knowledge amongst staff members on the concept of long-term digital preservation. Furthermore, the study revealed that the aspect of …
