The paper describes main features of a real-time forecasting and scheduling multi-agent solution designed for the LEGO Company. The design is based on Knowledge Genesis Group own multi-agent platform and technology, which provide real-time adaptive event-driven scheduling to replenish products to LEGO Branded Retail stores. The prototype system has been used to schedule 20 US-based LEGO retail outlets for a yearlong trial period and has achieved the following results:Reduction of lost sale from 40% to 16%; Increase in service level from 66% to 86%;Increase in profitability 56% to 81%. The results show a considerable potential value for full scale LEGO supply chain multi-agent solution which would be able to dynamically and adaptively re-schedule deliveries in real time.

We can perceive a sound position from binaural signals using mainly head-related transfer functions (HRTFs). Using the theorem presented herein, we can display a sound image to a specific position in virtual auditory space by HRTFs. However, HRTF is defined commonly in a free-field, and a virtual sound image is perceived as a dry source without reflection, reverberation, or ambient noise. Therefore, the virtual sound space might be unnatural. The authors developed a software-based virtual auditory display (VAD) that outputs audio signals for a set of headphones with a three-dimensional position sensor. The VAD software can display a dynamic virtual auditory space that is responsive to a listener's head movement. Subjective evaluations were conducted to clarify the relation between the perceived reality of virtual sound space and ambient sound. Evaluation results of the reality of the virtual sound space displayed by the VAD software are introduced.

The objective of this study is to utilize students' data to forecast their future grades, and to identify the students who would benefit from educational counseling. To achieve these purposes, we propose a Bayesian network model as a forecasting method. A Bayesian network is a graphical model that presents the dependence relationship among some variables in a graph structure. By calculating the probability value using the model, it is possible to make forecasts. Moreover, in this study, to facilitate the construction of a Bayesian network model, data mining is introduced.

Data integration is the fundamental to global Enterprise Application Integration (EAI) and Business Intelligence (BI) for decision support in a company. Different from those existing solutions offered by IT companies and other techniques, like Web Service, which usually are approaches for data integration on high-level, we contribute a novel solution for data integration of remote devices on low-level. This paper describes a fully scalable and configurable middleware which uses a range of technologies-Component-Oriented Programming, Message Queuing, XML and Topic-based Publish/Subscribe design pattern-to release the power of parallel processing with distributed data. Steps for the design and implementation of remote data integration middleware are the main topic of this paper. It is designed as a soft-gateway to link upper-level PCs with lower-level data transfer units, and implemented by extracting the key part of data communication out of its original holder so that the UI only cares about how to display data.

An object-based image processing technique is applied to detect inundated areas using Land sat images. An interoperable Web-based system was developed to conduct the analyses so that redundant steps in Land sat image processing can be effectively eliminated. A review process is used to discover and develop suitable algorithms to automatically detect inundated areas and immediately transfer the results to the Web-based interface. This is a significant improvement over currently available methods for inundation detection systems. The tool is expected to be a practical inundated area detection function and be applicable across wide-reaching areas.

A new 6D mesh/torus (Tofu) interconnect is implemented in the K Computer for achieving a performance of more than 10 petaflops. As expected, among its many interesting properties, such interconnect has large variations of latencies for communications within a node-group (intra-node-group) or between them (inter-node-group). Inspired by their works while recognizing the superior features of the recently published interlaced bypass torus (iBT) network that can help reduce such variations, we propose a new 6D mesh/iBT interconnect by replacing the 3D torus of Tofu by a 3D iBT. Our new interconnect suppresses the latencies for inter-node-group communications to dramatically improve the overall performance for the entire network. Adapting an industrial standard network simulator NS-3, we study different communication patterns of the added iBT networks under different bypass schemes. We find that the simulated average latencies of our network are 40% less than those of the Tofu interconnect for all tested patterns.

We investigate sets of conditions with respect to narrower drawing of tree-structured diagrams on an integral lattice. We found that under certain sets of conditions there are practical procedural algorithms for narrower drawing of tree-structured diagrams, while under other sets of conditions there are none. Based on our findings, we present efficient algorithms that provide narrower placement satisfying given amorphous conditions. In intractable conditions, we propose a constraint-based algorithm for drawing tree-structured diagrams with a minimum-width by limiting the number of cells. Our results provide a criterion for deciding under given conditions, whether to use procedural or constraint-based algorithms to draw a tree-structured diagram.

Modeling of the value transfer of service based business systems is often based on the value normalization in terms of the value of money. We identify that the normalization is neither applicable for not normalizable properties of services of XaaS/EaaS (everything as a service) nor contributing to modeling the business nature of service based systems. We explore from a knowledge engineering approach the foundation of value modeling factors including "unit of account" and "value normalization". We propose a holistic formula for assisting tradeoffs on the modeling factors. We identify possible not normalizable situations and introduce a service value broker mode as solution initiatives with demonstrative cases.

This paper proposes a method to recommend the relevant information of the document which recorded in the development support systems such as BTS and VCS. We improve a system which we implemented in previous work with the method proposed in this paper. Our method get a document from the support systems, extract the word, then calculate the feature vector based on the TF-IDF value of each word. In the experiment, we apply the proposal method to the dataset from an open source software projects, and evaluate the recommendation accuracy between the six clustering algorithm. The result of the experiment shows that the proposed method improves the recommendation accuracy compared with the previous work.
