There are two alternative display metaphors for Augmented Reality (AR) screens: a see-through window or a magic mirror. Commonly used by task-support AR applications, the see-through display has not been compared with the mirror display in terms of user's task performance, even though the “mirror” hardware is more accessible to general users. We conducted a novel experiment to compare participants'...
Lack of spontaneous pretend play is an early diagnostic indicator of autism spectrum conditions (ASC) along with impaired communication and social interaction. In a previous ISMAR poster [2] we proposed an Augmented Reality (AR) system to encourage pretend play, based on an analogy between imaginative interpretation of physical objects (pretense) and the superimposition of virtual content on the physical...
Children with autism are often found to lack facility for pretend play. It is believed that this deficit is linked to linguistic, social and creativity competencies in autism. We observe that both Augmented Reality (AR) and pretend play involve processing of information that is coupled with real scenes while not necessarily being directly perceived. This research therefore examines the potential of...
Recently, Multicasting is increasingly used as an efficient communication mechanism in the internet. Secure group communication is vital for many group-based applications such as pay-per view. One solution is to let all members in the group share a group key that is used for encrypting the data. To ensure perfect backward and forward secrecy, this shared group key has to be updated with every membership...
When emergency occurs, a reasonable and efficient resource scheduling system is urgently needed to deal with influences caused by emergency. In regard to the scheduling problem of single one-time consumption resources in the emergency logistics system, this paper establishes a resource response decision model with the goal of minimum emergency response time, least saving points, highest reliability...
Today economic integration all over the world not only accelerates the development of the international logistics, but also makes the problem of the international logistics risk increasingly prominent. As a result, an increasing number of companies begin to pay more attention to the international logistics risk management, especially the issue of risk assessment. From the characteristics of the international...
Based on chain catering industry, the paper sets up a supplier selection index system, the relevance between indexes are reduced through factor analysis, then, supplier can be analyzed by the model of C2R. Further more, to achieve the dynamic selection of supplier, life cycle of enterprise development is introduced, which make contribution to the integration of supply chain. Finally, the method of...
To locate the dairy distribution center (DC), reliability is cosidered as a measure of distribution sevice level, instead of only taking distribution cost into account. A mathematical model is presented. Firstly the existence and calculation of reliability are described in detail. Then genetic algorithm is used to solve the model, and the optimal solution of the model was obtained by selecting the...
The paper focuses on information sharing of a two-level supply chain composed of a manufacturer and a retailer. Based on the principal-agent theory, under considering risk costs a mechanism is designed to improve effort level of information sharing, and different parameter terms of incentive and supervisory mechanism to ensure the validity of mechanism are discussed. The results show by selecting...
This paper studies price discount contract coordination of a three-level supply chain. Under the stochastic market demand, previous price discount contract did not consider shortage cost. We present an approach by adding out-of-stock cost parameters which improves price discount contract of three-level supply chain. The supply chain can reach coordination and the optimal profits of the supply chain...
Information sharing incentive and supervisory mechanism enhances the current supply chain management environment. Based on the principal-agent theory, this paper studies how the core enterprise provides an incentive and supervisory mechanism to the partner enterprises, so as to improve their effort level of information sharing. In the designed mechanism, the liner function is firstly induced to describe...
Robust control for uncertain nonlinear systems based on T-S fuzzy model is discussed in this paper. Firstly, a T-S fuzzy system is adopted to model the uncertain nonlinear systems. Then, for the system with input variables adopting standard fuzzy partitions, a new sufficient condition to check the stability of T-S fuzzy system with uncertainty is derived, which is expressed in terms of linear matrix...
