The need to quantify aleatory and epistemic uncertainties has been widely recognized in the engineering applications. Aleatory uncertainty arises from inherent randomness, whereas epistemic uncertainty is due to the lack of knowledge. Traditionally uncertainty has been quantified by probability measures and the two uncertainty components are not readily differentiated. Intervals naturally capture...
Hybrid memory designs, such as DRAM plus Phase Change Memory (PCM), have shown some promise for alleviating power and density issues faced by traditional memory systems. But previous studies have concentrated on CPU systems with a modest level of parallelism. This work studies the problem in a massively parallel setting. Specifically, it investigates the special implications to hybrid memory imposed...
Remaining useful life (RUL) estimation is an important part in modern prognostic and health management (PHM) approach. In this paper, a particular prognostic named similarity-based RUL estimation is proposed. In some complex condition, typical methods will perform inefficient, and in engineering application background, some traditional methods may be hard implemented. On the other hand, similarity-based...
Stereoscopic Warehouse plays an important role in the modernization of the logistics field. It is characterized by an informatization, automation, high efficiency, and often used in regional distribution center. In some special occasions or due to special field, the stereoscopic warehouse must be with tandem storage space in the reason that putting all of the racks parallelly in a single storage requires...
This paper presents a methodology to perform cost-benefit analysis on the application of Prognostics and Health Management (PHM) technology for equipment. The purpose of the methodology is to estimate the economic feasibility of the application of the PHM technology. This paper discusses the calculation of economic metrics for PHM technology, and determines the potential Return on Investment (ROI)...
Traditional bridge cranes waste a large amount of energy because payload oscillation causes the operator to move the massive bridge back and forth in order to damp out the swing. The energy efficient bridge crane (EEBC) is a new crane concept that adds a Micro Bridge fine-positioning stage to the typical dual-bridge crane. With this Micro/Macro dual-bridge design, there is the potential to save energy...
In this paper, a novel method is proposed to perform saliency detection in news video. This method comprises bottom-up attention model which considers low level features to produce bottom-up saliency map and top-down attention model which utilizes high level factors to generate top-down saliency map. In bottom-up attention model, color image is represented as quaternion. Then the quaternion discrete...
The paper analyzes the traditional hook and inline hook's imperfection—easily to be detected and be recovered. To improve the inline hook technology, authors put forward a new technology called secret inline hook which has greater confidentiality and can avoid the malware's detection and falsify effectively. The technology has been successfully applied to the automatic analysis system of malware behaviour...
Offline program profiling is costly, especially when software update is frequent. In this paper, we initiate a systematic exploration in cross-version program profile migration, which tries to effectively reuse the valid part of the behavior profiles of an old version of a software for a new version. We explore the effects imposed on profile reusability by the various factors in program behaviors,...
A proof-of-concept prototype of optical sub-wavelength switching fabric is demonstrated. The prototype supports petabit switching capacity with agile service granularity and low power consumption.
Based on the analysis of building energy efficiency features, considering the construction of energy efficiency factors, this paper AHP establish a comprehensive evaluation of building energy efficiency design model based on grey theory. This model mainly combines quantitative analysis, qualitative and quantitative analysis methods to overcome the evaluation's the subjectivity and arbitrariness, and...
A clear picture of ultrafast charge carrier dynamics, exciton-phonon interactions and frequency upconverted lasing properties in ZnSe nanowire was established through a comprehensive pump-fluence and temperature dependent two-photon-excitation study.
The optical absorption properties of the thin-film solar cell (SC) is an important manifestation of its performance. Finite-difference frequency-domain (FDFD) method is employed to discretize the Maxwell's equations for the designed structure. The relationship between the absorbed power density with the design structure and the incident angle were deeply explored. Our numerical results can provide...
Developing entrepreneurial quality education and Cultivating the university students' entrepreneurship and innovative ability, is to meet the trend of China's higher education reform which focuses on developing the quality education for cultivating the compound, innovative and applied oriented talents. China's higher educational circles now have formed the consensus that is urgent to strengthen the...
Against the background where the entrepreneurial economy is replacing the managerial economy, the study on the entrepreneurial firms' knowledge management mechanism facing their customers in the wider sense is becoming the key to upgrade these firms' customer knowledge management competence. Thus, based on the a conceptual model construction of entrepreneurial firms' entrepreneurial orientation and...
This paper introduces relational contract to the field of knowledge management, defines relational rent in the knowledge network's cooperation, defines knowledge asset specificity of the core enterprise and the agent organization in knowledge network, and analyses the different influences of the discount factor and the knowledge asset specificity on the self-enforceability of relational contract....
The problem of wireless security for the downlink of MISO-OFDMA systems operating over a frequency-selective channel is investigated. By exploiting the dimensions provided by multiuser MISO-OFDMA systems for random user selection and beamforming, a novel physical-layer security method is to achieve low probability of interception (LPI), which let the attacker's equivalent channel be a random one,...
Turbo equalization is an iterative technique for the equalization and decoding of data that has been transmitted over the inter-symbol interference (ISI) channels. A number of suboptimal and low-complexity equalization algorithms have been developed to replace the optimal maximum a probability (MAP) equalizer. In this paper, we present an improved turbo minimum mean-squared error (MMSE) equalization...
We investigate the junction leakage current and device performance for 45nm SiGe/Si pMOSFETs using various silicide technology. It is found that with the conventional Ni silicide method, the leakage current of a SiGe/Si junction is large and attributed to band-to-band tunneling and the generation-recombination process. The two leakage contributors can be suppressed quite effectively when a Si cap...
Three different programming methods, the conventional CHE injection, CHE with a positive substrate bias (CHE-P) and pulse agitated substrate hot electron injection (PASHEI) were compared to obtain the reliable multi-bit/level operations in 90nm SONOS memory. It is found that both CHE-P and PASHEI methods can improve the cycling endurance and retention characteristic for 2 bits operations. The CHE-P...
