RODA is an open-source full-fledged digital preservation repository capable of ingesting, managing and providing continuous access to various types of digital objects, namely textdocuments, raster images, relational databases, video and audio. It is supported by open-source technologies and makes use of existing standards such as the OAIS [1], METS [2], EAD [3] and PREMIS [4].

According to topological quantum chemistry (TQC), a class of electronic materials has been called obstructed atomic insulators (OAIs), in which portion valence electrons necessarily have their centers located on some empty Wyckoff positions (WPs) without atom occupation the lattice. The obstruction centering these coinciding with host atoms is nontrivial and results metallic boundary states whe...

The paper presents the architecture of experimental Content-Based Image Retrieval (CBIR) system APICAS ("Art Painting Image Colour Aesthetics and Semantics"). This system has been developed within a doctoral thesis which aims to provide a suite of specialized tools for CBIR within a digital library of art images. The high-level architecture suggested in this work takes OAIS as a basis and adds ...

The OAIS Reference Model framework has been adopted by many organizations and institutions, including the government departments and digital libraries. This paper, upon the basis of the introduction to the Reference Model of Open Archival Information System, discusses and analyses the preservation metadata schema of the Military Academy Digital Library Application Software System of China, incl...

In the beginning, SPAR, the National Library of France's repository, was designed as the OAIS softwarified. It was intended to be a "full OAIS", covering all preservation needs in one tidy system. Then as its potential revealed itself across the library, high hopes arose for a do-it-all digital curation tool. Yet in day to day preservation activities of the BnF, it turns out that SPAR's growth ...

Imaging through random media is an important problem with many applications including optical remote sensing and bio-optics. In this paper, we will investigate the applications of Radiative Transfer Equation (RTE) in optical imaging. In particular, we study off-axis intensity subtraction (OAIS) and cross-polarization intensity subtraction (CPIS) imaging techniques. These techniques were propose...
