Continuing to improve computational energy efficiency will soon require developing and deploying new operational paradigms for computation that circumvent the fundamental thermodynamic limits that apply to conventionally-implemented Boolean logic circuits. In particular, Landauer's principle tells us that irreversible information erasure requires a minimum energy dissipation of kT ln 2 per bit erased,...
The turret system is one of the key functional components of the CNC lathe. Therefore it is important that the reliability of the turret system is optimised. In this paper, an imperfect preventive maintenance strategy, based on the Weibull distribution, for the turret system of the CNC lathe is proposed. The restoration and failure intensity increase factors are consistent with a uniform distribution...
Cloud computing has been evolved from server based context to service-oriented context. This transformation poses lots of challenges to a cloud environment in terms of cloud service reliability and information security. In most of the aspects of current cloud service environment, lot of information exchange taking place without much security. In this context cloud computing, with reliability and security...
The design of path allegiance metric (PAM) based routing protocol leverages upon a trust management framework proposed in our earlier works. The PAM routing protocol strives to provide data plane security in mobile ad hoc network and its working is based upon the belief, disbelief and uncertainty components of the trust management framework which assigns a trust metric based upon the packet forwarding...
Internet of Vehicles, an emerging industry, is being gradually popularized and applied. This paper is to propose a new construction method to neural network ensembles that based on the key technology to multi-sensor data fusion of Internet of Vehicles system, which is an effective solution to the problems such as the information collection about vehicle traffic. Training a group of neural networks...
This research is an attempt to identify the impact of effectiveness of the maritime simulator training program on different factors of needs and interest of the program. Model is developed to understand the impact. Data was collected from the course participants attending various simulator based training programmes from three training centers. Confirmatory factor analysis was employed to examine the...
This paper proposes a complete set of dynamic reliability quantitative assessment method which is applicable to any type of relay protection system. First, taking into account the comprehensiveness and representativeness, choose the reliability assessment indexes for relay protection system. Secondly, establish the dynamic fault tree model of the relay protection system reliability and transform the...
In the context of swift development of P2P e-commerce, it is critical to defending both customers and sellers from being victimized by probable deception stemming from uncertainties, vagueness and ambiguities that characterize the interactions amongst unfamiliar dealers. Accordingly, credit standing concerning each business partaker plays a decisive part in preventing fraud in P2P transactions and...
In this paper, the effect of crosswind on triple natural draft dry cooling towers is studied and analyzed. Concerning this area, many researches have concentrated on one cooling tower. This research focuses on the mutual effects of the adjacent towers' performance, and also makes a comparison between the efficiency of the three cooling towers in windy and no-wind conditions. Three dimensional governing...
Data-driven research is increasingly ubiquitous and data itself is a defining asset for researchers, particularly in the computational social sciences and humanities. Entire careers and research communities are built around valuable, proprietary or sensitive datasets. However, many existing computation resources fail to support secure and cost-effective storage of data while also enabling secure and...
This paper is a continuation of a previous work regarding deception detection in concurrent engineering. In earlier work, we studied the deception detection techniques, analyzed the deceptive information in concurrent engineering and identified the concepts to represent the deception. Earlier work revealed that ‘Sharing of Reliable and complete information’ plays a significant role in implementing...
The purpose of this study is to investigate the intention to use the cloud sphygmomanometer in Taiwan. This study also aims at providing suggestions on the popularization of cloud medical services. This study was established in a way that the model constructs in Technology Acceptance Model (TAM) were adapted to the context of cloud sphygmomanometer application in health management. Scale items on...
As the technology for acquiring and storing images becomes more prevalent, we are faced with a growing need to sort and label these images. At this time, computer vision algorithms cannot parse abstract concepts from images like a human. As a result, there may be performance gains possible from the integration of human analysts with computer vision agents. We present an image triage system which facilitates...
Cloud computing brings new technologies and concepts that favor communication services and data storage. Services like OneDrive, Google Drive and DropBox increase data availability and provide new features as synchronization and collaboration. This article aims to assess the availability and performance of private cloud storage service. A set of models that use a hierarchical strategy is proposed...
Cascading failures (CFs) in a complex product are the failures of interconnected functions in which the crash of a function can trigger the failure of successive functions. They can affect product function failure probability seriously, and their root causes analysis is a very complicated and challenging task. Therefore, it is significant to develop an applicable analyzing method considering the effects...
In this paper, we present the "Slow Start Problem" in participatory sensing applications where a service is provided based on data collected by participants. The slow start problem refers to the initial stage in participatory sensing service deployment, during which service adoption remains sparse and, hence, the collected data does not offer adequate coverage. Predictive models, learned...
Remaining useful life (RUL) prediction is a key link in prognostics and health management. More accurate RUL prediction results will lead to more reasonable decision making on sequential management activities including maintenance, replacement, spare parts ordering, etc. In engineering practice, many products exhibit more volatile degradation paths when they have high degradation rates. By this observation,...
Despite the consistent advances in visual features and other Content-Based Image Retrieval techniques, measuring the similarity among images is still a challenging task for effective image retrieval. In this scenario, similarity learning approaches capable of improving the effectiveness of retrieval in an unsupervised way are indispensable. A novel method, called Cartesian Product of Ranking References...
Increased end user reliability expectations coupled with the deployment of complex electronic systems in product applications such as automotive, military and avionics is driving a continual growth in the duration of validation testing.
In this paper, we propose a Skyline service selection approach based on QoS prediction. We first consider the QoS history records as time series and predict the QoS values by using Autoregressive Integrated Moving Average (ARIMA) model to provide more accurate QoS attributes values. And then we calculate the uncertainty of the prediction result by adopting an improved Coefficient of Variation. In...
