Multilayer network analysis has become a vital tool for understanding different relationships and their interactions in a complex system, where each layer in a multilayer network depicts the topological structure of a group of nodes corresponding to a particular relationship. The interactions among different layers imply how the interplay of different relations on the topology of each layer. For a...
This paper proposes a vehicle blind spot detection (BSD) system to reduce the traffic accident when car was changing lanes on the road. The cameras are installed at the bottom of the left and right side view mirrors. The system reaches 99% vehicle detection rate and is applicable during daytime and nighttime without high-cost radar. Furthermore, the system integrates with functions of auto cycle video...
In order to solve the problem of traffic accidents that caused by drivers and passengers open the door abruptly, this paper proposes a door open alarm (DOA) system that uses the camera as the sensor, and applies two analog cameras that set at the both side view mirrors to get the video information. This paper is based on image processing to develop the algorithm and has been implemented on Renesas...
We are witnessing the giant leap of Smart Cities and the prosperity of Internet of Things (loTs), but the anomalous vehicle surveillance issues in Intelligent Transportation Systems (ITS) are still challenging, especially when more computing tasks are migrated from Cloud center to the network edge. Different research studies attempted to tackle this problem, however, existing approaches are either...
Recently the quick development of virtual technology has made technology-aided learning more versified and education revolution more advanced. With visual and audio stimulation, technology-aided teaching can make student pay more attention than traditional way. Currently the way of learning idioms in elementary school is of more traditional way, which, without multiple interactions with students,...
Growing attention is being paid to the use of game-based learning in education, due to the rapid progress of information technology Internet. Students need to cultivate not only their own abilities, but also the ability of collaboration after graduation. However, collaboration must be directed by appropriate guidance in order to demonstrate the expected results, the rules of the game guide can be...
The purpose of the study was to investigate the interface design of a web-based formative assessment system. The present study was focused on question presentation and feedback design. A total of 28 college students participated in the study. Usability questionnaires were used to collect qualitative and qualitative data. The results are provided for online educators, learning management system developers,...
Modern machine-learning techniques greatly reduce the efforts required to conduct high-quality program compilation, which, without the aid of machine learning, would otherwise heavily rely on human manipulation as well as expert intervention. The success of the application of machine-learning techniques to compilation tasks can be largely attributed to the recent development and advancement of program...
In this study, a game integrated historical events were designed for improving and promoting students' motivation and understanding for history education. For this reason, the epistemological beliefs were incorporated in the model to explore students' digital games preference by applying technology acceptance model (TAM). A total of 112 fifth grade students in an elementary school were participated...
This paper demonstrates a high performance brain-computer interface (BCI) that allows users to dial phone numbers. The system is based on Canonical Correlation Analysis (CCA) and the automatic artifacts removal system based on BSS-CCA method and Steady-State Visual Evoked Potential (SSVEP). Through six frequency bands (9Hz, 10Hz, 11Hz, 12Hz, 13 Hz, 14Hz) displayed on the screen, subjects can choose...
A rare-earth free white light-emitting material is attained by synthesizing ZnXMn1-XS (ZnS:Mn) nanostructures caped with poly (9,9-di-n-hexylfluorenyl-2,7-diyl) (PF). The photoluminescence spectrum of ZnS:Mn/PF nanocomposites shows a narrow band emission peaked at 440 nm and a broad band emission ranging from 500 nm to 650 nm under ultraviolet (UV)-light excitation. The blue light is attributed to...
In this paper, we present a distributed complex event processing (CEP) engine for Internet of Things and its applications. A CEP Engine combines information from a variety of sources. It looks for patterns in these event streams and then responds in real-time. Complex event processing is an effective mechanism to analyze object data, to reason sensing events, and to trigger responding actions for...
Fuzzy C-Means (FCM) clustering is the most well-known clustering method according to fuzzy partition for pattern classification. However, there are some disadvantages of using that clustering method, such as computational complexity and execution time. Therefore, to solve these drawbacks of FCM, the two-phase FCM procedure has been proposed in this study. Compared with the conventional FCM, the usage...
Recently, research has been conducted to explore the prediction schemes to identify the severity of bug reports. Several text mining approaches have been proposed to facilitate severity prediction. However, these studies mainly focus on the textual information of the bug reports. Other attributes of the bug reports have not been comprehensively discussed. In this paper, we investigate the influences...
A MCU-based charger for the LiFeO4 battery pack is implemented in this paper. The main circuit is a full-bridge phase-shift converter. The user can select the charging strategy and observe the state of charge (SOC) of the battery from the operation interface. Moreover, the proposed charger system communicates with the battery management system via the I2C interface, and generates the charging current...
This paper presents a new CMOS inverter (CGTFET), which is composed of a Gated control IIP for load transistor (Gated-IIP) and a tunneling field effect transistor (TFET) for driven transistor. Based on the measurement data of Gated-IIP and TFET devices published, we have for the first time drawn the load lines and the quiescent point line (Q line) of the new designed CGTFET compared with the conventional...
XOR based RAID 6 systems outperform other RAID systems. Among the XOR (exclusive OR) based RAID-6 schemes, RDP has better performance than others by a narrow margin. However, the RDP code scheme cannot take full advantage of parallel hardware implementation of XOR codes. In this paper, we propose an extension of the double-erasure-correcting RDP code called EDP, which consists of a parallel decoding...
IPTV (Internet Protocol Television) is a very important field in the network development. Comparing to the traditional television, the IPTV combines the digital contents like media. The communication and the advertisement with the interaction serve into the emerging business model to provide the users to watch television service. Because the IPTV contains many merits; therefore, the world holds the...
This paper proposes a novel fast dehazing method based on dark channel prior. The dark channel prior is the phenomenon about normal outdoor images containing at least one low energy pixel around a block among three channels. It helps roughly estimating the air mediums thickness, which decreases the scene transmission. We propose a variation of optical model whose single atmospheric attenuation coefficient...
The dynamical network topology is the source of most challenges in VANETs (Vehicle Ad hoc Networks). In urban area, however, it is feasible to meet the challenge by taking advantage of the heavy traffic. This paper proposes a location aware virtual infrastructure (LAVI) based on recognition memory. Combining the memory of past cooperation with the location information, the mobile nodes can construct...
