Reliability testing has become extremely important in modern electronics as the soft error rate has been increasing due to technology scaling. The testing must be controllable, generic, done before deployment, cheap, and fast. Even though fault injection is often the most appropriate solution considering these requirements, it is very time-consuming. This work proposes a hybrid fault injection framework...
With the rapid advances in IoT technologies, the role of IoT gateways becomes even more important. Therefore, improving the reliability, availability and serviceability (RAS) of IoT gateways is crucial. Nowadays, Linux is widely adopted for core enterprise systems not only because it is a free operating system but also because it offers advantages in regards to operational stability. With many Linux...
Multicore architectures are increasingly becoming prone to transient faults. In this paper we present Shield, a middleware to provide transactional applications with resiliency to those faults that can happen anytime during the execution of a processor but do not cause any hardware interruption. Shield is inspired by the state machine replication approach, where computational resources are partitioned,...
DRAM is a crucial component in computing systems, and is expected to be even more important as data-intensive applications become more prominent. A key challenge in advancing DRAM technology is the growing cost of refresh operations, which can impose a large impact on the energy efficiency of DRAM modules. Existing refresh mitigation techniques all require hardware modifications, which may be undesirable...
Today, both the rapid improvement of process technology and the arrival of new embedded systems with highperformance requirements, have led to making the current trend in processors manufacturing shift from single-core processors to multi-core processors. This trend has raised several challenges for reliability in safety-critical systems that operate in high-risk environments, making them more vulnerable...
Some approaches and techniques that allow conducting of complex physiological research using closed-architecture measurement systems of different manufacturers are discussed. The experience in developing a system with flexible configuration and in solving arising problems by virtue of integration of equipment using an external synchronizing device, is described. Parallels are drawn with the modern...
Modern software systems provide many configuration options which significantly influence their non-functional properties. To understand and predict the effect of configuration options, several sampling and learning strategies have been proposed, albeit often with significant cost to cover the highly dimensional configuration space. Recently, transfer learning has been applied to reduce the effort...
Communications within power converters is becoming increasingly important particularly with the evolution of multilevel converters having distributed control structures. In the not so distant past, communications were used primarily for reference point setting and monitoring. Currently however communication is taking on an integral role in the control of the power converters particularly those with...
Due to technology scaling, which means smaller transistor, lower voltage and more aggressive clock frequency, VLSI devices are becoming more susceptible against soft errors. Especially for those devices deployed in safety- and mission-critical applications, dependability and reliability are becoming increasingly important constraints during the development of system on/around them. Other phenomena...
This paper describes the design and construction of a portable solar-powered phone booth coupled with a GPRS/GSM module capable of providing reliable communication while being independent of the electrical grid and telephone land-lines. Each phone booth has a pay phone case with electrical and electronic circuits to control the phone booth's operation including its power consumption and its lighting...
This paper presents a Controller Area Network (CAN) communication system in the Field-Programmable Gate Array (FPGA), which is Xilinx Artix-7. Hardware circuits and the software flow char are described in detail. The reusable IP (Intellectual Property) technology is used in FPGA as the core controller. In addition, the CAN communication system is implemented by System-on-a-Programmable-Chip (SOPC)...
A novel approach of a test environment for embedded networking nodes has been conceptualized and implemented. Its basis is the use of virtual nodes in a PC environment, where each node executes the original embedded code. Different nodes run in parallel, connected via so-called virtual channels. The environment allows to modifying the behavior of the virtual channels as well as the overall topology...
This study investigates the opportunities for transmission power control (TPC) protocols in resource constrained wireless sensor networks (WSNs). The paper begins by creating a generalised model to describe the relationship between transmission power, communication reliability and energy consumption. Applying this model to the performance of state-of-the-art radio hardware, the maximum potential energy...

Each unit of LAN equipment has been evaluated for criticality. LAN good technical condition criteria are determined. Failures types, consequences and criticality for possible malfunctions are analyzed. Existing or emerging defects...
Solar energy generation requires efficient monitoring and management in moving towards technologies for net-zero energy buildings. This paper presents a dependable control system based on the Internet of Things (IoT) to control and manage the energy flow of renewable energy collected by solar panels within a microgrid. Data for optimal control include not only measurements from local sensors but also...
Transient faults continue to be a critical concern in a range of computing domains including: High-Performance Computing (HPC), scientific computing, and the automotive industry. While radiation-induced faults have been well studied and understood in microprocessors, their impact on computations on Graphic Processing Units (GPU) has received less attention. GPUs are now being used in a large number...
The integration of Internet of Things (IoT) and Cloud computing has brought the rising of IoT Clouds able to provide different kinds of IoT as a Service solutions consisting of various micro-services deployed in IoT devices (including sensors and actuators) interacting with different Infrastructure, Platform, and Software as Service (i.e., IaaS, PaaS, SaaS) running in the Clouds' data centres. On...
With the development of GPU and GPGPU, GPU heterogeneous cluster has been widely used in parallel data processing in data center. In data green and sustainable computing, power consumption is a problem worthy of consideration. Power consumption may cause temperature rise and the problems of reliability and performance will probably occur. So temperature management and controlling has become a new...
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.
