With the efforts of genome-sequencing technology, phylogenetic reconstruction based on molecular information requires massive computation. In this way, mathematical method, computer technology and other auxiliary means play key roles in enhancing the efficiency and accuracy of phylogenetic reconstruction. Maximum parsimony is a very important method for phylogenetic reconstruction, and it needs efforts...
With the increasing of the diversity of imaging methods, multimodal images are applied in more wide field. But due to the constrain of the bang, multimodal image are sometimes polluted by noise. Cross Bilateral Filter (CBF) is one of the state of the art method which can denoising two multimodal images which are polluted by noise at the same times. In this paper we proposed an Cross Integral Histogram...
The study uses augmented reality (AR) technology to integrate virtual objects into the real learning environment for language learning. The English AR classroom is constructed using the system prototyping method and evaluated by semi-structured in-depth interviews. According to the flow theory by Csikszenmihalyi in 1975 along with the immersive factors from Trevino and Webster in 1992, the proposed...
Nowadays, microblogs provide abundant text data. Mining valuable information from it becomes an interesting topic. Based on the topic model, things can be easily traced. The complete view of an event can help people make decisions. Once we can track topics in a specific domain, experts can rapidly react according to important events. In this paper, we proposed a LDA [2] based framework to capture...
Traditional e-learning approaches are not appropriate for in-classroom interactive learning due to lack of the on-line interaction attribute. With the card mode, reader/writer mode and peer-to-peer mode supported in NFC (near field communication) technology, the issues in traditional e-Learning methods can be largely enhanced. In this work, we propose an NFC-based interactive and ubiquitous learning...
Most algorithmic composition system is implemented based on the input of music parameters, which needs professional music and technology training to complete the automated composition. This paper proposed an innovated way called Geographic and Meteorologic Data Sonification System (GMDSS), to perform the data mappings into music for various devices such as hand phone or other hand-hold devices, and...
Peer interaction plays an important role during the learning process. Currently predominant paradigm of digital learning materials limits learners' interaction with their peers using traditional user interfaces. To cope with this problem, this study proposes an embodiment-based learning environment to facilitate more peer interactions. The effectiveness of the environment is evaluated by designing...
As we all know, it is an era of information explosion, in which we always get huge amounts of information. Therefore, it is in urgent need of picking out the useful and interesting information quickly. In order to solve this serious problem, recommendation system arises at the historic moment. Among the existing recommendation algorithms, the item-based collaborative filtering recommendation algorithm...
Game tree search is a classical problem in the field of game theory and artificial intelligence. Fast game tree search algorithm is critical for computer games asking for real-time responses. In this paper, we focus on how to leverage massive parallelism capabilities of GPU to accelerate the speed of game tree search algorithms and propose a concise and general parallel game tree search algorithm...
In view of the laboratory instrument data continuous acquisition and storage, designed a acquisition system based on LabView VISA function. Introduce the hardware structure of the Fluke PM6306 RCL meter and configuration of Agilent 82537B. The serial port communication based on the VISA function is reported in detail. Finally, the optimized data acquisition rate and the experimental results are presented.
This paper proposes a novel distributed parallel EM modeling technique to speed up the process of neural network modeling for EM structures. Existing techniques for EM modeling usually need to repeatedly change the parameters of microwave devices and drive the EM simulator to obtain sufficient training and testing samples. As the complexity in EM modeling problem increases, traditional techniques...
Owing to the slow circuit board level maintenance and fault location of wireless communications equipment, and technically demanding problems, the multi-state circuit board testing environment was establish to study the circuit board interface type, input and output signals, power supply and others. Based on the diagnostic strategies of multi-signal flow model optimization design, this paper designed...
Propagation and transmission of laser beam through tapered glass capillary were investigated for light microbeams. Transmittances of laser light at 488 nm and 633 nm through capillaries were measured to be up to 15%, depending on outlet diameters. By modeling the real capillary, transmittances were calculated using taper angles obtained from shape analysis and agree well with experimental ones.
As the important part of the virtual application system, the remote control software plays an important role in the interaction between system and user. With the rise of mobile Internet, the virtual desktop software which runs in PC has been very difficult to adapt to the demand for mobile communication. This paper mainly introduces mobile virtual application, which based on the Remote Desktop Protocol...
The rapid development in the field of computer graphics (CG) makes it quite easy to create photo-realistic images and videos. This brings forward an emergent requirement for techniques that can distinguish CG from real contents. In this paper, we propose a method that leverages human pulse signal to distinguish between CG and real videos that include human faces. We use a robust tracking method to...
The popularity and the large market share of mobile devices such as smart phones and tablets have had a significant impact on our daily lives. The full-fledged computing platforms render a ubiquitous means to deliver information and knowledge. This project aims to utilize such platforms to enhance computer science education, especially in curricula such as programming, mobile application development...
Technology in education has caused numerous of changes. The use of electronic books (e-books) is one of these changes, however, it is given the slower than expected growth. In other words, there is few complete consideration for using e-books materials into education. Therefore, this study proposes a framework to consider how to transfer the traditional textbooks into electronic textbooks called e-textbooks...
Open Flow, an essential technology in Network functions virtualization (NFV) implementation, enables software-dened networking (SDN) to develop from a simple concept and divides traditional switch into two parts: a data plane and a control plane. Because software-dened rules are used to control traffic, the concept of NFV was developed. Numerous virtualization studies on NFV have investigated conventional...
Today's multi-processor system-on-chip (MPSoC) systems increasingly have to deal with dynamically changing application workload scenarios. To cope with such dynamic application behavior, these systems could dynamically adapt the mapping of application tasks onto the underlying system resources to improve the system's performance. However, such performance improvement comes at the cost of a system...
