With the increasing complexity of wireless environment, scene, frequency band, antenna scale and other factors, it brings new challenges to wireless channel modeling. On the other hand, wireless communication solutions based on artificial ...

Maintaining timeliness and data freshness for real-time data objects has long been recognized as an important problem in real-time database research. Despite years of active research, most of the past work focuses on uniprocessor systems. In this paper, ...

Maintaining the freshness of real-time data is one of the crucial design issues in cyber-physical systems (CPS). Past studies have focused on designing update algorithms to minimize the workload imposed by a fixed set of update tasks while ensuring the ...

Although the deferrable scheduling algorithm for fixed priority transactions ( DS-FP) has been shown to provide a better performance compared with the More-Less (ML) method, there is still a lack of any comprehensive studies on the necessary and ...

Deriving deadlines and periods for update transactions so as to maintain timeliness and data freshness while minimizing imposed workload has long been recognized an important problem in real-time database research. Despite years of active research, the ...

Deriving deadlines and periods of update transactions for maintaining timeliness and data freshness has long been recognized as an important problem in real-time database research. Despite years of active research, the state of the art only focuses on ...

Recently, a new biometrics, finger-knuckle-print recognition, has attractive interests of researchers. The popular techniques used in face recognition are not applied in finger-knuckle-print recognition. Inspired by the success of Local Gabor Binary ...

This paper investigates the discovery of conditional functional dependencies (CFDs). CFDs are a recent extension of functional dependencies (FDs) by supporting patterns of semantically related constants, and can be used as rules for cleaning relational ...

In many telecom and web applications, there is a need to identify whether data objects in the same source or different sources represent the same entity in the real-world. This problem arises for subscribers in multiple services, customers in supply ...

Although the deferrable scheduling algorithm for fixed priority transactions (DS-FP) has been shown to be a very effective approach for minimizing real-time update transaction workload, it suffers from its on-line scheduling overhead. In this work, we ...

Maintaining the temporal validity of real-time data is one of the crucial issues in a real-time database system. Past studies focus on designing algorithms to minimize imposed workload by a fixed set of update transactions while maintaining data ...

This paper investigates the discovery of conditional functional dependencies (CFDs). CFDs are a recent extension of functional dependencies (FDs) by supporting patterns of semantically related constants, and can be used as rules for cleaning relational ...

In face recognition, the class mean of the training samples may deviate from the class center in small sample size. The method based on adaptively weighted fisherface is one of the approaches to deal with the problem. However, it didn’t consider the ...

A real-time object is one whose state may become invalid with the passage of time. A temporal validity interval is associated with the object state, and the real-time object is temporally consistent if its temporal validity interval has not expired. ...

The schedulability testing for the deferrable scheduling algorithm for fixed priority transactions (DS-FP) remainsan open problem since its introduction. In this paper, wetake the first step towards investigating necessary and sufficient conditions for ...

The periodic update transaction model has been used to maintain freshness (or temporal validity) of real-time data. Period and deadline assignment has been the main focus in the past studies such as the More-Less scheme [25] in which update transactions ...

As quality of service (QoS)-enabled component middleware technologies gain widespread acceptance to build distributed real-time and embedded (DRE) systems, it becomes necessary for these technologies to support real-time publish/subscribe services, ...

A real-time database is composed of real-time objects whose values remain valid only within their validity intervals. Each object in the database models a real world entity. The freshness of these objects is maintained by update transactions that sample ...

The vast variety of data available about a user in the telecom network can be used to create rich, personalized applications that are targeted to that user. For example, a user's current location can be used to offer a Restaurant Locater service that ...

The deferrable scheduling algorithm for fixed priority transactions (DS-FP) [23] is demonstrated to be a very effective approach for minimizing real-time update transaction workload while maintaining temporal validity of real-time data. This paper ...
