in the conventional design and analysis methods affecting parameters (loads, materials'strength, etc) are not set as probable variables. safety factors in the current codes andstandards are usually obtained on the basis of judgment and experience, which may beimproper or uneconomical. in technical literature, a method based on nonlinear static analysisis suggested to set reliability index on st...

Shrinking transistor sizes and reduced supply voltages, in combination with enhance CPU frequencies, increase the susceptibility of recent processors against external interference, as for example cosmic radiation. These emerge in terms of transient hardware faults, which can temporarily influence the system behavior, without necessarily leading to permanent damage. While this topic is well know...

one of the most important problems in the system reliability optimization is redundancy allocation problem that has been studied in different system configurations. k-out-of-n structure is a general system configuration and offers enhanced capabilities for analyzing more design problems. hence, in this paper, the redundancy allocation problem of k-out-of-n systems is studied. in the most previo...

Available networked embedded systems, e.g., in the field of automotive networks bind functionality statically onto electronic control units (ECUs). Thus, if a node fails, the functionality hosted by the control unit will be lost, and due to data dependencies, other functions on working nodes may not operate either. The same holds true for erroneous communication links which may lead to an isola...

High-speed target three-dimensional (3D) trajectory and velocity measurement methods have important uses in many fields, including explosive debris rotating specimen tracking. The conventional approach a binocular system with two high-speed cameras to capture the target’s 3D motion information. Hardware cost for is high, accurately triggering several difficult. Event-based recently received con...

This paper presents a novel hardware implementation of a disparity estimation scheme targeted to real-time Integral Photography (IP) image and video sequence compression. The software developed for IP image compression achieves high quality ratios over classic methodologies by exploiting the inherent redundancy that is present in IP images. However, there are certain time constraints to the sof...

Error detection plays an important role in fault-tolerant computer systems. Two primary parameters concerned for error detection are the latency and coverage. In this paper, a new, hybrid error-detection approach offering a very high coverage with no detection latency is proposed to protect the data paths of high-performance microprocessors. The feature of no detection latency is essential to r...

System reliability is an important aspect of real-time systems, because the result of a real-time application may be valid only if the application functions correctly and its timing constraints are satisfied. There are two kinds of faults, hardware and software faults, and the paper considers hardware transient faults. Full replication or full hardware redundancy can achieve a high degree of re...

We describe an architecture of an enterpriselevel storage control system that addresses the issues of storage management for storage area network (SAN) -attached block devices in a heterogeneous open systems environment. The storage control system, also referred to as the “storage virtualization engine,” is built on a cluster of Linux-based servers, which provides redundancy, modularity, and sc...

A comprehensive online test strategy requires both concurrent and non-concurrent fault detection capabilities to guarantee SoCs’s successful normal operation in-field at any level of its life cycle. While concurrent fault detection is mainly achieved by hardware or software redundancy, like duplication, non-concurrent fault detection, particularly useful for periodic testing, is usually achieve...
