The general structure and main principles of creating a multi-version post-severe NPP accident monitoring system, which consists of one wired and three drone-based wireless network subsystems, are proposed. Reliability block diagrams for the system are built. On the basis of the reliability block diagrams, reliability models of the system are developed. The dependence on probability of failure-free...
We proposes the development of a cyber-secure, Internet of Things (IoT), supply chain risk management architecture. The proposed architecture is designed to reduce vulnerabilities of malicious supply chain risks by applying machine learning (ML), cryptographic hardware monitoring (CHM), and distributed system coordination (DSC) techniques to mitigate the consequences of unforeseen (including general...
Most cluster-based rendering systems require at least one graphics processing unit (GPU) per node. However, there are many cluster systems which contain thin rack-mounted nodes that do not support GPUs. In this paper, we explore the utilization of such a system by combining it with a small commodity off-the-shelf tile rendering cluster. We call this a GPU-limited cluster because only those nodes responsible...
A wireless navigation system (WNS) is proposed that autonomously coordinates the motions of cooperating robots. The proposed WNS employs both Bluetooth technologies and wireless routing protocols that can discover routes around obstacles and other barriers to communications. A time-slotted, ad hoc on-demand distance vector routing (TAODV) protocol is designed to maintain secure, wireless communication...
An open source private cloud architecture environment is described that supports tablet-class computer devices as clients. The cloud architecture employs a Metadata server, Data servers, and Compute servers. The private cloud clients are treated as a limited resource device: limited in memory, view space and computing power. The client tablet makes requests to the Metadata server that maintains a...
This paper describes the mobile Ad-Hoc (wireless) network (MANET) for emergency scenarios in nuclear power plant (NPP). Authors proposed the system with such properties as flexibility and a self-forming and self-healing network topology that dynamically adjusts to the moving configuration per each intermediate routing node. It is also proposed to integrate MANET and Bluetooth-like technologies to...
A big data file transport (BDFT) protocol is presented that minimize overheads associated with packet streaming in Java. The BDFT protocol relies on block 1-data transfers, and the elimination of unnecessary data copying between the application layer and the send socket in the standard Java IO model. The implementation uses the Java New IO (NIO) and the Zerocopy libraries. Several experiments are...
The security of block and product ciphers is considered using a set theoretic estimation (STE) approach to decryption. Known-ciphertext attacks are studied using permutation (P) and substitution (S) keys. The blocks are formed form three (3) alphabetic characters (metacharacters) where the applications of P and S upon the ASCII byte representation of each of the three characters are allowed to cross...
