In Ethernet passive optical network (EPON), the distance between optical network units (ONUs) and optical line terminal (OLTs) is in a large range of changes. Only dividing ONUs into a network according to locations will influence the user's QoS. In view of this situation, this paper puts forward a planning strategy of ONUs clustering. We first consider the economy, network delay and network reliability,...

software-defined networking (SDN) uses a centralized control plane to manage the whole network. If the scale of the network is large, it is necessary to divide it into multiple domains. Since the network scale becomes larger, the probability of failure occurrences is higher. Therefore, it is important to guarantee the control plane resilience in multi-domain SDN. However, the existing approaches cannot...
The distribution system operation in Beijing, China, is investigating on an AC/DC topology for expanding a local distribution system. The feature is to install multi-terminal DC interconnections (MTDI) among three substations, in order to achieve un-interrupted load transfer as well as better loading sharing during primary transformer N-1 outages. This paper presents a reliability assessment of hybrid...
With increasing miniaturization of electronic devices and systems, the dimension of solder joints and pitches has been continuously scaling down, while the current density carried by solder joints increasing significantly, consequently a critical issue, electromigration (EM), has become a key reliability concern. The EM behavior in the joint is mainly dependent on the magnitude and distribution of...
Maintenance strategy impacts the reliability of distribution network directly. Common distribution network maintenance strategies contain corrective maintenance and preventive maintenance. However, the existing reliability assessment methods ignore the effects of preventive maintenance. This study showed the influence of preventive maintenance on the system failure rate by describing the preventive...
It is important to select an appropriate representation of wind power uncertainty for unit commitment (UC). Unlike previous studies predefining the scope of uncertainty, this paper presents a method to co-optimize wind power uncertain intervals and unit commitment. The proposed method is aiming to select the optimal wind power uncertain intervals and achieve the optimal trade-off between economics...
A non-orthogonal waveform superposition scheme for high reliable wireless communications is analyzed, and certain design rules for the scheme are discussed. The capacity of the scheme is superior than that of Nyquist signaling by use of waveform superposition and excess bandwidth. It's proved that the channel capacity can eventually reach the capacity of waveform channel, when the superposition multiplicity...
Network-on-chip (NoC) is a major communication technique for 3D integrated circuits (ICs). In order to achieve higher throughput and lower latency with less system cost, horizontal and vertical wireless links are adopted to apply in the 3D NoCs. So far, the reliable routing scheme has been regarded as a lightweight and high-efficiency mechanism to guarantee the performance of the faulty 2D/3D NoCs...
The key to safe operation of heavy-haul combined train is whether the train can be operated and controlled synchronously. In this paper, the model of GSM-R wireless transmission system on Datong-Qinhuangdao (Da-Qin for short in the following paper)heavy-haul railway and failure and recovery model are established based on DSPN. The result of simulation by TimeNet4.0 shows that the probability of data...
Multi-level STT-RAM cell is able to boost the memory density at the expense of read/write reliability. However, the induced data integrity issue in STT-RAM memory can be effectively masked by a wide spectrum of applications with intrinsic forgiveness, which belong to the specific domain such as multimedia, synthesis and mining. In this work, we leverage the reconfigurable capability of MLC STT-RAM...
In this paper, the impact of multi-edge LDPC symbols on the performance of the bit-interleaved coded modulation (BICM) system is investigated. To avoid the performance degradation caused by multi-edge symbols, we propose a multi-edge elimination-based interleaver design for the LDPC-coded BICM system. It can improve the decoding performance of LDPC-coded BICM system with a little extra computational...
Marketing channel as the downstream end of a supply chain assumes a prominent role for delivering company's offerings to customers, meeting their demands, and creating cash flow for company. To ensure better customer relationship and secure more market power, retailing stores make efforts to differentiate themselves by introducing private brand products in addition to existing national brands. Globalization...
The magnetic field fluctuations in the power grid will produce geomagnetic induced currents (GIC) when magnetic storm occurs. Monitoring and analysis of the GIC is an important new task. At present, although the domestic GIC monitoring devices can monitor GIC, they are unfavorable for installation for their large size and weight. This paper proposes a GIC monitoring model which is based on embedded...
Distribution channel as one of important entities in the service sector, how channel members operate is seriously relevant to the general public. Though categorized as the down-stream of the supply chain, leveraging market power for own interest is a way of life for channel members, as opposed to coordination and collaboration of activities with mutual trust performed by tiers of suppliers and manufacturer...
Marketing channel as the downstream end of a supply chain plays a crucial role in generating cash flow and meeting the demands of customers. The extant body of literature postulates that antecedent-consequence links that customer perceived value and service quality foster customer loyalty, leading to long term profitability. Nowadays, given the proliferation of global hypermarket organizations and...
In this work a linear field model is adopted to study the reliability of capacitors which are manufacturing in Win's production line. Two testing techniques, a constant voltage and a ramped voltage testing modes, are compared in order to examine in various sizes and shapes which testing techniques may give us a better way to predict the capacitor lifetime. It seems to us that the constant voltage...
