Astronautically Phased Mission System (APMS) has the characteristics of sophisticated system structure, complex mission profile and varied system working modes and states. For these characteristics, this paper analyses the mission profile and reliability features (sequential, correlate and dynamic) of APMS, and proposes a method of reliability synthetic modeling considering multi-feature for APMS...
Different kinds of maintenance events in practical maintenance have different effects on equipment operation and task success. Based on the characteristics of multiple events and uncertainties of maintenance events, this paper analyzes the influence of various maintenance events on maintenance cost decision under different maintenance times, and determines the influencing factors of maintenance cost...
Most existing weakly supervised localization (WSL) approaches learn detectors by finding positive bounding boxes based on features learned with image-level supervision. However, those features do not contain spatial location related information and usually provide poor-quality positive samples for training a detector. To overcome this issue, we propose a deep self-taught learning approach, which makes...
Short-term tracking is an open and challenging problem for which discriminative correlation filters (DCF) have shown excellent performance. We introduce the channel and spatial reliability concepts to DCF tracking and provide a novel learning algorithm for its efficient and seamless integration in the filter update and the tracking process. The spatial reliability map adjusts the filter support to...
With the degradation of electrical connector performance, the intermittent failure (IF) may occur in connector when subject to vibration, thermal and humidity stress. Intermittent failure is generally a precursor to a permanent fault (PF). During the whole life cycle of the electrical connector. The dynamic parameters such as frequency and duration of intermittent failure, evolve continuously with...
In the multi-temporal InSAR technique, a deformation map is obtained by arc integration. Therefore, the reliability of an arc solution directly influences the precision of the final result. Many methods have been proposed to estimate arc parameters, but few have evaluated the arc quality. In this study, the influence of phase ambiguity is analyzed and two indicators are defined to identify the arcs...
Discriminative correlation filters (DCF) have aroused great interests in visual object tracking in recent years due to the accuracy and computation efficiency. However, occlusion is still the main factor that affects performance. In this paper, a spatial-temporal consistent correlation filter utilizes the rich features extracted from a pre-trained convolutional neural network (CNN) is proposed to...
Spatial outlier detection in wireless sensor network (WSN) can detect the objects whose non-spatial attributes are significantly different from their spatial neighbors, so as to ensure the reliability and accuracy of sensor data before decision-making process. The main drawback of existing spatial outlier detection algorithms is high user-dependency, which is not suitable for dynamic WSN data. This...
online social networks are progressively being adopted among young people in developing countries. The public is questioning why so many people adopt this technology in many aspects of their lives? The purpose of this study is to understand the acceptance of social networks by Thai students. We used traditional TAM's behavioral constructs: subjective norms (SN), perceived usefulness, perceived ease...
Because of the characteristics of the availability and practicability, mobile media technology had got a rapid development in the whole world. So, people now often use mobile devices through a mobile application (APP). Based on this, this study established a mobile application customer engagement model to carry on the investigation and research about mobile application of customers' recommendation...
Employing the Theory of Planned Behavior (TPB), this study aims to find determinant factors that have influence over individuals' intention to cyberbully others. Using a scenario-based questionnaire, the data were collected from 96 students in Universiti Teknologi Malaysia. According to the results, only subjective norms reflected to be significant over cyberbullying intention, while the rest of variables...
Performance of safety applications of vehicular networks largely depends on the reliability of the communication channel. However the IEEE 802.11p channel is unreliable according to the previous measurement-based work, which reported that the whole communication range is a “gray-zone” and the packet inter-reception time suffered from blackouts with a relatively high probability. Besides the 5.9 GHz...
Products arranged in the same zone usually have some spatial correlation, function relation and the impact of environmental stress, which usually causes coupling effect with other products in the same zone. This kind of coupling effect affects products' quality, and may influence the veracity and comprehensiveness of the quality analysis. To solve this issue, starting from changing the traditional...
The study herein summarized was focused on the development of a method to derive reliable estimates of the quality of movement of stroke survivors via the analysis of wearable sensor data. Data was collected from 34 subjects while they performed a battery of functional movements that are part of a standard clinical assessment. The quality of movement was assessed using the Functional Ability Scale,...
Knowledge sharing is a key process that influences individual and organizational performance. The significance of sharing knowledge is confirmed through enormous number of previous studies. However individuals are not always motivated to share their knowledge. There are different factors might encourage or hinder employees to engage in knowledge sharing. This study aims at investigating the impact...
The problem of search for delay of broadband signals on the basis of code sequences is considered. The problem arises when using long code sequences in conditions of limited signal observation time and high requirements to reliability and synchronization accuracy. In these conditions use of various non-optimal methods and search algorithms, in particular, sequential-parallel search, consecutive algorithms...
The vision of cyber-physical systems (CPSs) considered the Internet as the future communication network for such systems. A challenge with this regard is to provide high communication reliability, especially, for CPSs applications in critical infrastructures. Examples include smart grid applications with reliability requirements between 99–99.9999% [2]. Even though the Internet is a cost effective...
Despite employing the architectures designed for high service reliability and availability, cloud computing systems do experience service outages and performance slowdown. In addition to these, large-scale cloud systems experience failures in their hardware and software components which often result in node and application (e.g., jobs and tasks) failures. Therefore, to build a reliable cloud system,...
As conventional tools for assessing and improving the ability of older adults to perform functional tasks that entail executive functions (EF) are limited, there is a need to identify alternate approaches including the use of simulated environments. The objectives of this study were (1) to investigate differences in EF in older and young adults as determined by their performance on the Adapted Four-Item...
This research aimed to analyze the impact of the competence, work ethic, professionalism and motivation of people (lecturer and staff) on their performance. The data taken from questionnaires to 317 respondents and interviewed the 12 respondents. Data were analyzed using multiple regression analysis. The results showed that the Competence, Work Ethics, Professionalism and Motivation on the lecturer...
