In this paper, the iterative learning control problem using uniform quantizer with encoding and decoding scheme is considered, in which the system output is transformed and encoded firstly, and then transmitted back to the controller and decoded for input updating. Zero-error convergence of the output to the desired reference is realized by utilizing this updating scheme. The results are extended...
Digital terrestrial television multimedia broadcasting - advanced (DTMB-A) is digital terrestrial television broadcasting (DTTB) standard proposed by China, which has been accepted by ITU as the international DTTB standard in July, 2015. By adopting several advanced technologies, such as nearcapacity channel coding and modulation as well as improved frame structure, DTMB-A can provide fast system...
Single frequency network (SFN) has been widely used in digital terrestrial television broadcasting (DTTB) systems. In this paper, we propose a SFN structure for DTMB systems using satellite links as the main program distribution networks. The proposed structure is more suitable for constructing national wide or large area DTTB SFN under complicated environments. The network structure and key technologies...
The coming of big data era seriously challenges many traditional database techniques and it also explains the popularity of NoSQL databases, Cassandra, for example. Storing data in these NoSQL databases is a prerequisite for applying some popular large-scale data processing frameworks such as Hadoop or Spark. In this paper, we propose a model transformation approach that transforms class diagrams...
In order to effectively solve the uncertainty small-samples fault diagnosis problem, a practical data-driven grey-based fault detection and diagnosis (FDD) method for complex equipments is investigated. Firstly, an improved fuzzy-grey relational analysis (FGRA) technique is proposed by introducing dynamic identification coefficient and fuzzy relational weight. Compared with the traditional Deng's...
The specification of Trusted Network Connect (TNC) proposed by Trusted Computing Group (TCG) can improve network security from the inside, which has become the focus of security research field.. A policy server based on TNC architecture, which focus on endpoint integrity, is proposed. We discuss its work flow and communication process. and the simulations show the feasibility of this server used in...
Rapid and accurate fault detection and diagnosis (FDD) is gaining importance for complex equipments because of the need to increase reliability and to decrease possible loss. In this paper, an intelligent fault diagnosis method is presented by using case-based reasoning (CBR) methodology to infer and classify various failures. Firstly, the case representation and the case base are established according...
In recent years, there has been an increasing interest in the fly-by-wireless technology to address the problems and costs introduced by cables, which is considered as a revolution in aerospace vehicle architecture for avionics instrumentation and control. As early investigates suggested, some basic features and advantages of Asynchronous Transfer Mode (ATM) mechanism have been considered for avionics...
In recent years, the study on novel type parallel mechanisms with less degrees of freedom (DoFs) has attracted the attention of many scholars at home and abroad. In this field, type synthesis of parallel mechanisms which can realize decoupling is a frontier subject. To this end, based on the rotational conditions (RCs) presented in our pre-paper, this paper introduces the concept of accompanying movement...
With its unique and perfect performance, Nano-TiO2 film has been widely used in many fields. However, the preparation of Nano-TiO2 film has significant sustainability issues including heavy use of energy and materials, low production efficiency, toxic chemical emissions, etc. In this research, case study is conducted on a Low Pressure Chemical Vapor Deposition (LPCVD) process for nano-TiO2 film preparation...
