Bytewise approximate matching algorithms have in recent years shown significant promise in detecting files that are similar at the byte level. This is very useful for digital forensic investigators, who are regularly faced with the problem of searching through a seized device for pertinent data. A common scenario is where an investigator is in possession of a collection of “known-illegal” files...

-This work is based on a previous Fast Frequency Hopping Spread Spectrum (FFHSS) transceiver designed for wireless optical communications. The core of the transmitter was a discrete Direct Digital Synthesizer (DDS). In the first prototype the DDS control and the digital synchronization signal were generated using a Programmable Logic Device (PLD), besides a discrete external filter was necessar...

The Archaeology Data Service (ADS) is a digital archive that has been promoting good practice in the use of digital archaeological data and supporting research, learning and teaching with high quality and dependable digital resources for twenty years. The ADS does this by preserving digital data in the long-term and by promoting and disseminating, open and free datasets, gathered from all secto...

The aim of this study was to assess the applicability of gray scale inversion in performing digital linear endodontic measurements. Standardized digital images were taken of 40 extracted human permanent single-rooted teeth with K-files size 15 placed at different lengths in the root canal, using the CDR Wireless(®) digital system. All images were treated with Positive, a digital tool that inver...

This article is devoted to the analysis of methods for creating a knowledge base digital library based on semantic model authority files. The also describes practical aspects an electronic legal encyclopedia Creation network files significantly optimizes quality and speed searching resources in libraries creates basis intellectualization information retrieval. examines detail existing approache...

Digital technology encourages hope of searching across and between different media forms (text, sound, image, numeric data). We describe topic searches in two different media: text files and socio-economic numeric databases and also for transverse searching, whereby retrieved text is used to find topically related numeric data and vice versa. Direct transverse searching across different media i...

The BBC Archive now contains around 15 Petabytes (single copy) of uncompressed audio-visual files that have been created from videotapes since 2007. This process is still on-going, creating an ever growing file-based collection of the BBC's television history. This is of course in addition to the new content now being produced that begins life as files. This paper focuses on the technology aspe...

Sharing in silico experiments is essential for the advance of research in computational biology. Consequently, the COMBINE archive was designed as a digital container format. It eases the management of files related to a modelling result, fosters collaboration, and ultimately enables the exchange of reproducible simulation studies. However, manual handling of COMBINE archives is tedious and err...
