Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing. In this paper, we address the construction of an efficient PDP scheme for distributed cloud storage to support the scalability of service and data migration, in which we consider the existence of multiple cloud service providers to cooperatively store and maintain the clients’ data. We prese...

Today, the Internet trust is a critical framework that forms fundamental premise for network security. Several identity federations are deployed to embody classic theory of framework. However, in an emerging blockchain-based decentralized system, we need model dynamically grown/shrunken trust. This paper models elasticity by formalizing PDP(policy decision point)s enrolling entities and introdu...

Krisis global pasca merebaknya epidemi Covid-19 berdampak pada proses belajar mengajar (PdP). Masalah utama pdP selama adalah keterbatasan dalam melakukan kegiatan tatap muka di kelas. Oleh karena itu, diperlukan bantuan pembelajaran agar PdP dapat berjalan optimal meskipun tidak ada interaksi antara guru dan siswa. Penelitian ini menyoroti penerapan Augmented Reality untuk mendukung jarak jauh...

Pickup and Delivery Problems (PDPs) are a relevant class of vehicle routing problems in which objects or people need to be collected and distributed. These problems have many applications in logistics, ambulatory services and robotics. In this thesis, we survey the static and dynamic PDPs appearing in the literature, we provide a classification scheme for them, and we show the relations between...

Peptide nucleic acids (PNAs) are DNA-mimicking molecules in which the sugar-phosphate backbone is replaced by a pseudopeptide backbone composed of N-(2-aminoethyl)glycine units. We determined whether double-stranded molecules based on PNAs and PNA-DNA-PNA (PDP) chimeras could be capable of stable interactions with nuclear proteins belonging to the Sp1 transcription factor family and, therefore,...
