Definition and Development of a Control Concept Applied in Elements Distributed for Manage Them Using IoT

In recent years,the Internet has gradually developed into a mature tool,which can integrate technologies involved in different application scenarios.The Internet allows the integration of solutions to different problems,which benefits both users and companies.The Internet of Things is a further development of the Internet,which can further realize the interconnection of people,machines,and things.The work of this paper mainly focuses on the use of Internet of Things technology to achieve efficient management.A wireless device is designed in the paper,which can be integrated in a helmet.This helmet can be used in some specific scenarios.Managers can use the Internet of Things technology to call the data generated by the hearing equipment and lighting equipment in the helmet to identify users.These helmets can be managed through a network platform.On the network platform,in addition to the helmet,some other components can be allowed to access,making the platform more universal and convenient.This paper elaborates on the design and development of the project and shows how to use it for effective time management in the skating rink.

An Approach to User Interface Specification with Attribute Grammars

An approach to supporting user interfaces using an attribute grammmar combined with an event model is described. The main emphasis is how to represent a multi-thread dialogue model in direct manipulation user interfaces. It is shown that control sequence within dialogues, communication with other dialogues,and some computations for applications can be specified with a syntactic and semantic notation. The attribute grammar specification can be implemented using an attribute grammar interpreter embedded in the runtime structure supporting communication, synchronization, and dialogue execution.

Mobile Terminal Management in 3G

Recently, Terminal has become one of the key issues in the 3G development. In the paper, we study the mobile terminal management in 3G network. Based on the analysis of problems encountered with the terminals, the paper describes the use cases of terminal management. A system architecture with its function components of mobile terminal management system is proposed. Moreover, a possible implementation solution is introduced and described. A Management Information Model （MIM） for terminal management is also proposed to support the management services.

MSDA:multi-subset data aggregation scheme without trusted third party

Data aggregation has been widely researched to address the privacy concern when data is published,meanwhile,data aggregation only obtains the sum or average in an area.In reality,more fine-grained data brings more value for data consumers,such as more accurate management,dynamic price-adjusting in the grid system,etc.In this paper,a multi-subset data aggregation scheme for the smart grid is proposed without a trusted third party,in which the control center collects the number of users in different subsets,and obtains the sum of electricity consumption in each subset,meantime individual user’s data privacy is still preserved.In addition,the dynamic and flexible user management mechanism is guaranteed with the secret key negotiation process among users.The analysis shows MSDA not only protects users’privacy to resist various attacks but also achieves more functionality such as multi-subset aggregation,no reliance on any trusted third party,dynamicity.And performance evaluation demonstrates that MSDA is efficient and practical in terms of communication and computation overhead.

An Object-Oriented Multi-Thread Dialog Model

This paper presents a multi thread dialog model using extended state transition network model combined with an object oriented event model to specify and manage user interface. The model provides multi thread dialogs and the concurrent executing of user interface and application procedures. The forms of class based concurrency possible in the model emphasize the human computer interaction and exploit the concurrency across objects and within an object. Dialog descriptions using extended state transition networks, the automatic extraction of concurrency, the facilities for performing synchronization and communicating, generalization and specification, and the smooth transition from dialog design to programming language implementation are also given in this paper.

Colored Nets as a Formal Approach to Event-Driven Interfaces

Modern object-oriented interactive applications have a tendency to be dguult to specie and to des l'gnbecause of dynamicity A formal model based on the integration of communicative nets and colored nets withmpchronous channels is proposed ic cater for this need. Three kinds of nets modeling fore e components of interfaceare given in this paper.The model provides natural descriptions of multi-thread dialogs and the concurrent executingof user interface and aPPlication Procedures and can facilitate rapid protonning and automatic interface codegeneration.
