Although integrated modular avionics (IMA) provides many advantages such as the reduced weight and higher efficiency for system operations, safety problems with correlations of system states come up due to its resource sharing mechanism. Correlations of system states contribute to the fault propagation in IMA systems. In other words, when a shared resource goes into an error state, components which...
The smart substation is an important part of smart grid. By transmitting GOOSE (Generic Object Oriented Substation Event) and MMS (Manufacturing Message Specification) message among devices, the smart substation can realize the functions including, protection, control, alarm etc. Currently available smart substation secondary system's operation and maintenance analysis doesn't take account of the...
In this paper, the problem of estimating the motion and shape parameters from the infrared signature of precession object is addressed. To limit the scope of this work, only objects with shape of flat-plane, cone, cylinder, cone-cylinder combination are considered. Different from the current research, the parameter estimating is based on signal modeling. First, a signal model is proposed to approximate...
Recently, there are many big data analytic models which have been developed. In this paper, we consider the spatial panel model and extend the STIRPAT model. These two models are integrated for us to investigate the effects of the urbanization on energy consumption in China. Our study is based on the panel data of 29 provinces in China from 2002 to 2013. Several conclusions are made from our investigation...
This study has a purpose to investigate the adoption of online games technologies among adolescents and their behavior in playing online games. The findings showed that half of them had experience ten months or less in playing online games with ten hours or less for each time playing per week. Nearly fifty-four percent played up to five times each week where sixty-six percent played two hours or less...
This paper proposes a method using SDG (Signed Directed Graph) to investigate fault propagation mechanism of IGBT faults in traction system of CRH (China Railway High-speed) trains. A TCG (Time Causal Graph) model is obtained from the BG (Bond Graph) model of CRH5 traction system first; then, an SDG model is derived from the TCG model in accordance with fault tree propagation backward derivation....
Reliability analysis based on failure mechanism takes advantage of unnecessary requirement for the field data, compared with the traditional method based on probability statistics. Current reliability analysis for systems based on failure dependence mainly focus their views on either failure level or failure process level, but barely from the aspect of failure mechanism. Our previous work used Mechanism...
We propose a Success Rate (SR) estimation model for Correlation Power Analysis (CPA) attack on AES-128 encrypted devices. The SR is a ratio between the number of successful attacks to obtain secret key and the total number of attacks. There are two key features in the proposed model. First, we derive the Second Order Standard Deviation (SOSD) of the processed data to analyze their switching activities...
Transformer oil-based nanofluids have gained wide recognition for its higher dielectric strength compared with pure oil. But few researches focus on its thermal capability. In this paper, computational models working on different kinds of nanoclusters in transformer oil fluidic system have been developed at an atomic-molecular level to explore the temperature impact on the systems' viscosity. SiO2...
In this paper, we model an essential feature of underwater mine hunting with the aim of suggesting improvements to existing search tactics. We derive the effect of correlation between multiple sonar images of an underwater mine target - where a correlator represents the relation between images of the same target. For example, with duplicate images of the same target the correlator shows the absence...
At present, many mobile video perception studies are intended to describe the degree of correlation between the influencing indicators, but most of them are based on the experience of experts, so the results are imperfect comparatively. In this paper, a mobile video perception assessment model based on the improved analytic hierarchy process (IAHP) is proposed by mapping the key quality indicators...
Innovation is widely recognized as one main contributor to a firm's competitiveness. To conduct innovation, an organization must utilize its tangible and intangibles resources. The current study is aimed at examining the effect of intangible resources, namely human, organizational and relational resources on innovation in the context of service firms (i.e., tutoring agencies) in Indonesia. In addition,...
Electronic systems, like they are embedded in road vehicles, have to be compliant to functional safety standards like ISO 26262 [1], which limit the impacts of malfunctions for safety critical systems. ISO 26262, for instance, defines different safety levels for road vehicles, which require different means and measures for a safety compliant system and its development process like risk analysis and...
In order to verify whether there is a correlation between human behavior and EEG signal, proposes a method based on exploratory analysis to study the relationship between human behavior and EEG. Through the acquisition of mice EEG and respiratory signal under sleep state, using exploratory analysis modeling to construct a transmission system of the linear time invariant multi-resolution model, then...
Adaptive Augmented Reality (A2R) presents the environment and useful information for the user decision making, this is in real time. Nowadays, there is a gap in A2R acceptance research, although A2R is an emergent technology, specific studies of A2R acceptance has not been conducted yet. In contrast, Augmented Reality (AR) acceptance and recommendation acceptance has actually been addressed in several...
The analysis of the quantization error in fixed-point arithmetic is usually based on simplifying assumptions. The quantization error is modelled as a random variable which is independent of the quantized variable. This contribution investigates the wordlength reduction of a digital multiplier in greater detail. The power spectrum of the quantization is expressed by the power spectrum of the multiplier...
Widely linear (WL) receivers can fulfill single antenna interference cancellation (SAIC) of one rectilinear (R) or quasi-rectilinear (QR) co-channel interference (CCI). The SAIC technology for QR signals has been shown to be less powerful than SAIC for R signals. To overcome this limitation, a SAIC/MAIC enhancement using three-inputs WL frequency-shift (FRESH) receiver has been introduced for QR signals...
The autoregressive models (AR) and moving-average models (MA) are regularly used in signal processing. Previous works have been done on dissimilarity measures between AR models by using a Riemannian distance, the Jeffrey's divergence (JD) and the spectral distances such as the Itakura-Saito divergence. In this paper, we compare the Rao distance and the JD for MA models and more particularly in the...
The zero-inflated negative binomial regression model is used to study the influencing factors of casualties in water traffic accidents. The Pearson correlation analysis is used to obtain the influencing factors of casualties in water traffic accidents. The ZINB regression model is established to evaluate the influencing factors. According to the analysis results, influencing factors are sorted in...
This preliminary study investigates feasibility of a running speed based heart rate (HR) prediction. It is basically motivated from the assumption that there is a significant relationship between HR and the running speed. In order to verify the assumption, HR and running speed data from 217 subjects of varying aerobic capabilities were simultaneously collected during an incremental treadmill exercise...
