Friend-to-Friend (F2F) storage systems were shown to suffer from two significant limitations. First, users with a small set of friends are penalized by lack of available storage for their needs, while users with many friends get overloaded with resource requests. Second, friends are typically in close geographical proximity to each other, and thus their online times are synchronized, leading to low...
Location-based mobile applications such as Foursquare and Jiepang help bridge the gap between offline and online. People that we encounter and connect with around physical resources such as conferences, provide opportunities for extending our social networks from offline to online. We give a preliminary study on the relationship between the online and physical social networks in terms of the online...
This paper describes a novel method that enables users to teach systems the phoneme sequences of new words through speech interaction. Using the method, users can correct mis-recognized phoneme sequences incrementally by making corrective utterances. Each corrective utterance may include the whole or a segment of the word. During the interaction, if the correction using the utterance results in a...
Considering constructional algorithms for solving Traveling Salesman Problem (TSP), the solution process of Nearest Neighbor (NN) is the simplest one, but its performance is the worst. This paper proposes an improved NN algorithm for solving TSP in Euclidean Plane. Firstly, the algorithm searches four corner-nodes from all nodes, and gets a simple tour which only includes four corner-nodes, obtains...
In this paper, we propose a novel method for a robot to detect robot-directed speech, that is, to distinguish speech that users speak to a robot from speech that users speak to other people or to themselves. The originality of this work is the introduction of a multimodal semantic confidence (MSC) measure, which is used for domain classification of input speech based on the decision on whether the...
Risk analysis for flood hazard due to dam break is complex system problem. An information model for integrated complex factors of the system is useful for dam break risk analysis. Firstly multiple factors are analyzed using scenario analysis method, including factors and their uncertainty in environmental, engineering operation and hazard consequences. Then an information model of risk analysis for...
Integrated modeling, planning and management for watershed are complex system problems. Information sharing of digital watershed is a key for integrated modeling, assessment, collaboration, planning and management. This research analyses the methods of information sharing, and presents intelligent information sharing technologies. Framework of watershed integrated modeling, planning and management...
With the rapid development of electronic technology and the accelerating update speed of the electronic products, the number of waste mobile phones is growing exponentially. Study on the recycling and utilization of waste mobile phones has caused worldwide concern. Based on the Theory of Reverse Logistics, the paper designs a recycling logistics network suitable for waste mobile phones, which consists...
The small and medium-sized logistics enterprises are the main body in China's logistics industry. In the increasingly open logistics market in China, whether small and medium -sized logistics enterprises can develop and improve overall competitiveness is the key for the rapid growth of China's logistics industry. This paper analyzes growth of small and medium-sized enterprises based on the enterprise...
In this paper, we propose a novel method to detect robot-directed (RD) speech that adopts the Multimodal Semantic Confidence (MSC) measure. The MSC measure is used to decide whether the speech can be interpreted as a feasible action under the current physical situation in an object manipulation task. This measure is calculated by integrating speech, image, and motion confidence measures with weightings...
AJAX, a core technology of Web 2.0, is aroused attention by both industry and academia. Google Maps is a classical Web application service based on AJAX. This paper presents a WebGIS framework of web application with AJAX and XML data. Based on Google Maps service, the framework uses XMLHttpRequest objects which call the XML data and load the geographic information dynamically. The framework is consisted...
