Remanufacturing has been characterized as a critical component of the circular economy and an engine of the closed loop supply chain process. However, few researches focus on consumers' intention to purchase remanufactured products. To enrich researches on this, we propose an extended theory of planned behavior (TPB) by adding more explanative variables to investigate the affecting factors of consumers'...
With rapid proliferation of internet and advancement in video streaming techniques, demand for video content over the internet is on the rise. In this era of digital transformation the end user consumption of video content, is not just limited to conventional television sets, but extends to multiple viewing platforms like laptops, mobile phones, tablets, connected TVs, gaming consoles etc. As the...
There is a continual growth of test and validation in high reliability product applications such as automotive, military and avionics. Principally this is driven by increased use and complexity of electronic systems installed in vehicles in addition to increased end user reliability expectations. Furthermore product development cycles continue to reduce, resulting in less available time to perform...
Reliability of safety critical systems such as nuclear power plants and automobiles has become a significant issue to our society. As more computing systems are utilized in these safety critical systems, there are high demands for verification and validation (V&V) techniques to assure the reliability of such complex computing systems. However, as the complexity of computing systems increases,...
The article shows an analysis of the reliability of a compression-ignition engine used in a medium duty truck. The criterion for the reliability assessment was the decrease in combustion chamber tightness. The analysis was based on the results of compression pressure tests and leak-down tests conducted during a long-term operation of 5 trucks. Experimental survival functions and then continuous reliability...
Cloud computing, which is a relatively new approach to distributed computing, uses cloud infrastructures that automatically scale to support an application's hardware requirements, and therefore, must have high reliability in order to meet user expectations. To achieve a high level of quality and reliability, cloud platforms and infrastructures must be tested thoroughly. Typically, cloud providers...
Expendable Launch vehicles remain the primary means of delivering payloads to orbit. 1 2 High reliability in these systems is vital to the safe delivery of the valuable payloads they carry. A considerable number of past launch vehicle failures can be attributed to propulsion subsystems. These subsystems contain combustion, control thrust levels, maintain vehicle stability, and withstand the dynamic...
The efficient development of a highly reliable system, such as a new crew launch vehicle, cannot afford to ignore the lessons of history. A number of interesting studies of launch vehicle failures provide very valuable, albeit qualitative “lessons learned” on measures that a risk-informed program should take. If schedule and funds were unlimited, a very intensive and exhaustive test program would...
In the product development process, test planning can be a time-consuming task, in particular, the test methods for product reliability are usually selected manually because many documents must be referred to when selecting suitable test methods. To make this process more efficient, we have been researched methods to support test planning. In this paper a new automatic selection method for test plans...
Third generation Intel??IBIST (IBIST) is the first full featured edition of what was originally envisioned in 1999. The objective was to create a standard infrastructure for validating, debugging, and testing high speed IOs (Input/Output) which could be supported by a common software toolset. This vision was realized in 2009 on Intel products. The IBIST methodology has become a standard at Intel....
This paper presents a new methodology for testing the adaptive digitally-calibrated pipelined ADCs. By the using the uncalibrated output codes, the health of the ADC under test can be reliably examined. We propose using ??the error signature?? which is obtained by integrating the absolute difference between the uncalibrated and exact output codes as a response to applying an on-chip generated test...
To benefit from grids, scientists require grid workflow engines that automatically manage the execution of inter-related jobs on the grid infrastructure. So far, the workflows community has focused on scheduling algorithms and on interface tools. Thus, while several grid workflow engines have been deployed, little is known about their performance-related characteristics, and there are no commonly-used...
In this paper a BISR architecture for embedded memories is presented. The proposed scheme utilises a multiple bank cache-like memory for repairs. Statistical analysis is used for minimisation of the total resources required to achieve a very high fault coverage. Simulation results show that the proposed BISR scheme is characterised by high efficiency and low area overhead, even for high defect densities...
This paper describes a benchmarking workload model for business process execution language (BPEL) engines for Web services. The proposed model is based on simulation of real world traffic conditions by defining a set of requirements which best characterize the end-users. The performance characteristics are evaluated on top of collected measurements such as success/fail rate, response times or round-trip...
Reliability is the probability that a system will perform its intended function for a specified period of time in a specified environment. Often, the reliability of a system cannot be directly measured through test to compare against its requirement because of programmatic constraints on testing. In cases where testing cannot adhere exactly to the defined mission profile, it is necessary to normalize...
