2015 3rd International Conference on Applied Computing and Information Technology/2nd International Conference on Computational Science and Intelligence (ACIT-CSI)
This paper has analyzed the property of the structure of MP3 file, and provided a parallel decoding method for the property. Thus, for CPU with multiple cores, this paper has provided a parallel decoding method based on multi-thread. The method can increase the utilization rate of CPU and decrease the decoding time while the load of each core of CPU is not balanced. At last, we have conducted three...
This paper analyzes the key technology of uninterrupted broadcast, describes the working principle and processes of the dynamic caching scheme. After extracting the features and needs, this paper adopts the UPPAAL based on timed automata theory to construct the model, and describes the expected properties by using TCTL language, and then performs automatic verification based on model checking. Eventually,...
It is predicted that Nankai Trough Earthquake will occur in the near future in Japan. Based on this prediction, we develop the disaster simulation by Projection Mapping. Our study aims to promote disaster information visualization, disaster reduction education and voluntary/active individual behavior for disaster reduction. We mapped the video to the diorama of the three-dimensional map model of Aichi...
Histograms of Oriented Gradients (HOG) feature has been successfully used in pedestrian detection and achieves high accuracy. This paper introduces a content retrieval algorithm based on improved HOG. The method has two steps which are adjusting the HOG structure by scanning the image with a sliding HOG window and reducing feature dimension by principle component analysis (PCA) technique. The experimental...
Systematically collected class attendance records of students in university let us possible to observe friendship networks among students through time. With the friendship networks observed by this method we study local structures, which are called ego-centric networks, of friendship networks and transition of the structures. In order to observe transition of egocentric networks we classify them to...
The mathematical models to represent the relationship between the thermal stress and the deterioration rate for electrical insulation are well established based on the Arrhenius law and appropriate underlying probability distributions for constant thermal stress. There are two kinds of methods to deal with the thermal lifetime: one is the two-valued discrete model representing 0 for alive and 1 for...
The network structures of supply chains (SC) are extremely complicated to understand in their entirety. However, complicated social challenges involving a chain of decision making might be realized through gaming simulations. This study uses a supply chain management (SCM) game to define effective strategies for decision making in a SC. The game rules and system architecture should be simple but should...
We have developed an intravenous (IV) infusion monitoring system in nursing-houses/hospitals. The system assists nurses to manage the IV infusion process by integrating hardware devices, composing of a drip-bag weight scale and a RFID/NFC tag reader, and an IV fusion monitoring software. A 6502-based microcontroller is used as a platform of connecting an s-type load cell sensor and a RFID/NFC reader...
It is very difficult for students who do not have a business career or experience to understand business models or structures. In addition, business models from the student viewpoint remain largely within a model-based understanding, and students do not have practical opportunities to create an image of business uncertainty. Our goal is to provide an experimental learning environment beyond the level...
Complexity science is a new field of science that help us to understand complex social phenomenon such as economies, traffics, wars, epidemics, mass actions, etc. On the other hand, multi-agents simulation (MAS) methods are useful and powerful tools for complex system science. They come to be applied to studies and analysis of complex systems along with the development of computers. It can be said...
Dissimilarity computed from frequency information obtained by applying three-dimensional Fourier transformation to a plasma video has been proposed. This paper defines the evaluation criteria for plasma videos in order to confirm which features the dissimilarity reflects on. To this end, a subjective experiment is conducted. From the experimental result, it becomes clear the dissimilarity reflects...
This paper investigates on the techniques to search for optimal configuration parameters sets for Hadoop HDFS (Hadoop Distributed File System). An optimization technique, so-called the automated benchmarking configuration methodology (ABCM) [4], has been proposed and demonstrated by employing a two-staged sampling technique in order to mitigate the computational complexity and cost of the search process...
This study explores how evolutionary changes of the rules affect the characteristics of the games in the Shogi species. There are Dai-Shogi (Big Shogi) variants that are played with a big board and numerous pieces, but almost all such variants are now obsolete. Only a variant called Chu-Shogi is still played by some people. In this paper, we evaluate the impact of special Chu-Shogi rules that are...
We are concerned with a card game called Daihinmin, which is a multi-player imperfect information game. Using Marvin Minsky's "Society of Mind" theory, we attempt to model the workings of the minds of game players. The UEC Computer Daihinmin Championship is held at The University of Electro-Communications every year, to bring together competitive client programs that correspond to players...
Clustering of web users is an important research field in web mining. Information of web user clusters have been wildly used in many applications, such as solution of website structure optimization, reconstruction of website and distribution of advertising business. In this paper, we convert web log data into a sparse matrix, and propose a novel approach to calculate influence degree of each web page...
StarCraft: Brood War is one of most-popular classic real-time strategy (RTS) games and has attracted much interest in recent researches. The Artificial Intelligence (AI) in StarCraft has not been that advanced, so professional players have consistently been stronger than any AI. We have considered the build order problem in RTS games for this paper and propose a simple human-like build-order management...
We studied the internal structure of snow by conducting a Ground Penetrating Radar (GPR) survey which has used for the study of the ground structure and the site in the past. First, the laboratory experiment was conducted to study variations in the radio wave's reflection patterns of the internal structure of snow at the Snow and Ice Research Center of NIED. Ice layers and water channels were created...
The purpose of this study is examining the eye movements of the understandability of cardinal direction. Specifically we give task to participants, which is to look north shown in each cardinal direction. In addition we were measuring the eye movement of until the reaction time for each cardinal direction. As a result, In the case of reaction time, the RTs increased with increasing design elements...
The mobile user behaviors data were usually collected by using embedded SDK in the Apps. However once too many device connected to the data collection system, the server has to deal with the high load. In this work, we design a new data collection strategy based on the FNV hash strategy in order to reduce the server load. Experimental results show that the strategy can effectively alleviate the pressure...
