This paper designed a 1-Mb HfOx-based embedded Resistive Random Access Memory (RRAM) device with a one-transistor-one-resistor (1T1R) structure, and systematically investigated its working temperature range. It noted that this embedded RRAM macro has a 1.6X working temperature range than previous design for some extreme environment. Using the peripheral-assisted technique, it can enable the error...
This paper presents the specifications for a network architecture of a squadron of Unmanned Aerial Vehicles to be used to scan rocket impact areas. It presents the main features of communication networks for multi UAV systems and the details of its application. In this context, we propose a network architecture based on XBee Pro 900HP S3B modules integrated to a hardware platform controlled by embedded...
Recent standardization efforts in IEEE 802.15.4-2015 Time Scheduled Channel Hopping (TSCH) and the IETF 6TiSCH Working Group (WG), aim to provide deterministic communications and efficient allocation of resources across constrained Internet of Things (IoT) networks, particularly in Industrial IoT (IIoT) scenarios. Within 6TiSCH, Software Defined Networking (SDN) has been identified as means of providing...
The challenge of failure management emerges in decentralized architectures due to the distributed nature of the layered control process. Failures in microgrid system may occur at the microgrid level or any of the control layers. A failure detection and response mechanism is required to attain a reliable, fault-tolerant microgrid operation. This paper introduces a Failure Management Unit as an essential...
Series-stacked server power delivery architectures have been proposed recently that can achieve much higher energy efficiency than conventional power delivery architectures. When servers are connected in series, differential power processing (DPP) converters can be used to regulate the server voltages when the servers are consuming different amount of currents. Server-to-bus DPP architecture has unique...
DC distribution is emerging as a solution for data centers, however the optimal system architectures have not been established in the industry. This paper first reviews the most recent studies, products and activities of DC distribution in data centers. A hybrid AC and DC distribution architecture is introduced by using both 415V AC and 380V DC together to achieve the data center reliability requirements...
This work presents the major characteristics and lessons learned by the development and prototype implementation of an event-oriented and cloud-based SCADA system that is constructed using a microservice architecture. The microservices are then utilized to propose an approach for implementing product-driven production systems under the RAMI4.0 specification.
Data assurance and resilience are crucial security issues in cloud-based IoT applications. With the widespread adoption of drones in IoT scenarios such as warfare, agriculture and delivery, effective solutions to protect data integrity and communications between drones and the control system have been in urgent demand to prevent potential vulnerabilities that may cause heavy losses. To secure drone...
There has been renewed attention given to High Speed Railways (HSR) in the US, in terms of adapting more speed, reliability, increasing passenger capacity and providing passenger centric services. Any future Train-To-Ground (T2G) communication system therefore has to embrace reliable signaling and control-specific needs of HSR, while also catering towards the high performance networking demands of...
The need for performance has motivated the increasing adoption of solid-state drives (SSD) both in personal computers and data centers. However, the high cost per gigabyte and reduced lifetime hinder the thorough replacement of hard disk drives (HDD) with SSDs. To mitigate these issues, several architectures have been conceived based on hybrid storage systems, but performance and dependability models...
This paper describes our blockchain architecture as a new system solution to supply a reliable mechanism for secure and efficient medical record exchanges. The Advanced Block-Chain (ABC) approach was designed to meet the demands in healthcare growth as well as in the new form of social interactive norms. It is going to revolutionize the e-Health industry with greater efficiency by eliminating many...
Recent developments induced by the Internet of Things (IoT) force a paradigm shift to deploy on demand services to a broad range of different computing architectures. Mainly single board computers (SBCs) gained a lot of attraction in recent years, shifting highly available processing power to service consumers and IoT devices. Simultaneously, container virtualization achieved a breakthrough by the...
In this paper, design of a novel Network on Chip (NoC) structure and its integration with Reliable Reconfigurable Real Time Operating System (R3TOS) are presented. NoC has been recently identified as a scalable communication paradigm to avoid the communication bottleneck in bus based communications. Dynamically Reconfigurable Field Programmable Gate Array (FPGA)s are particularly suited for applications...
This paper presents a methodology to calculate the worst-case reliability of smart distribution system. Impact of communication infrastructure failure on the system reliability is investigated in both substation-centered and decentralized multi-agent restoration management. Different communication infrastructure is also examined to evaluate the impact in the reliability of the substation centered...
The Wireless Sensor Networks (WSNs) are widely being used for monitoring different environments and are very effective for monitoring those areas where human presence can be critical. Meanwhile, Cloud Computing (CC) has emerged as a very large scale computational and storage service with pay-as-you-go usage model which has taken the WSN to entirely a new paradigm. This integration of WSN with CC provides...
In this paper, we outline the challenges we have encountered in mission critical system development projects based on public tendering processes and list reasons why the challenges we have faced are difficult to tackle. Furthermore, based on our experienc-es in the mission critical system provision domain, we see that the software-as-a-service (SaaS) model saves us from many of the shortcomings of...
Communication between air traffic controllers and pilots remains a vital part of air traffic control operations, and communication problems can result in hazardous situations. The modern Air Traffic Management (ATM) system has independent direct communication channels (CC) for each controllers operating at different radio frequencies. Currently, the main method of improving the reliability of controller's...
Evaluating architecture of aircraft power supply system precisely is the basis of optimizing aircraft architecture design. The multi-index evaluation of its architecture involves reliability, expense, maintainability, weight and power quality, which provides designers with the optimal decision information, including two steps: normalize individual evaluation index and export each single-index result;...
Reliability evaluation is a critical task in computing systems. From one side, the results must be accurate enough not to under-or over-estimate the overall system reliability (thus either resulting in a non-reliable system, or a system for which too expensive solutions have been adopted). On the other side, the time required for the analysis should be kept at the minimum. This paper presents some...
General Purpose computing on Graphics Processing Unit offers a remarkable speedup for data parallel workloads, leveraging GPUs computational power. However, differently from graphic computing, it requires highly reliable operation in several application domains. In this paper we present SIFI a reliability evaluation framework for soft-errors on AMD GPUs built on top of Multi2Sim, a micro-architectural...
