The increasing pervasiveness of the internet, broadband connections and the emergence of digital compression technologies have dramatically changed the face of digital music piracy. Digitally compressed music files are essentially a perfect public economic good, and illegal copying of these files has increasingly become rampant. This paper presents a study on the behavioral dynamics which impac...

Flexible digital library systems need to be able to accept, or “import,” documents and metadata in a variety of forms, and associate metadata with the appropriate documents. This paper analyzes the requirements of the import process for general digital libraries. The requirements include (a) format conversion for source documents, (b) the ability to incorporate existing conversion utilities, (c...

the aim of ideal canal preparation is to prevent iatrogenic aberrations such as transportation. the aim of this study was to evaluate the root canal transportation by reciproc file with and without glide path.thirty acrylic-resin blocks with a curvature of 60° and size#10 (2% taper) were assigned into two groups (n= 15). in group 1, the glide path was performed using stainless steel k-files siz...

Early digital forensic examinations were conducted in toto – every file on the storage media was examined along with the entire file system structure. However, this is no longer practical as operating systems have become extremely complex and storage capacities are growing geometrically. Examiners now perform targeted examinations using forensic tools and databases of known files, selecting spe...

File carving is a recovery technique which does not consider file tables or other meta-data which is used to organize data on storage media. As files can be recovered based only on their content and/or structure, this technique is an indispensable task during digital investigations. The main contribution of this paper is the description of procedures that allow for successful content-based reco...

Nowadays compressed files are very widespread and can be considered, without any doubt, with regard to the Digital Forensic realm, an important and precious source of probatory data. This is especially true when in a digital investigation the examiner has to deal with corrupted compressed files, which have been gathered in the collection phase of the investigative process. Therefore, in the com...

Digital objects are often more complex than their common perception as individual files or small sets of files. Traditional methods of preserving these complex objects such as migration may not be suitable for maintaining access to them in an economically and technically feasible way. Many of today’s preservation scenarios would benefit from a change in our understanding of digital objects. Ins...

Digitised and born-digital Audio-Visual (AV) content presents new challenges for preservation and Quality Assurance (QA) to ensure that cultural heritage is accessible for the long term. Digital archives have developed strategies for avoiding, mitigating and recovering from digital AV loss using IT-based systems, involving QA tools before ingesting files into the archive and utilising file-base...
