Conventional centralized cloud computing is a success for benefits such as on-demand, elasticity, and high colocation of data and computation. However, the paradigm shift towards “Internet of things” (IoT) will pose some unavoidable challenges: (1) massive data volume impossible for centralized datacenters to handle; (2) high latency between edge “things” and centralized datacenters; (3) monopoly,...
This paper proposes the first attempt to utilize multi-modal learning method for the representation learning of the solar radio spectrums. The solar radio signals sensed from differ-ent frequency channels, which present different characteristics, are regarded as different modalities. We employ a multimodal neural network to learn the representations of the solar radio spectrum, which can distinguish...
Big Data and the popularity of mobile Internet play an indispensable role on the reconstruction of supply chain in China. This article will combine big data, mobile Internet and the supply chain effectively and point out the competitive advantages created by big data and mobile internet from many aspects of time, cost, efficiency, customer experience, etc. Taking warehouse-type supermarkets as an...
Graph partition quality affects the overall performance of parallel graph computation systems. The quality of a graph partition is measured by the balance factor and edge cut ratio. A balanced graph partition with small edge cut ratio is generally preferred since it reduces the expensive network communication cost. However, according to an empirical study on Giraph, the performance over well partitioned...
In order to provide quicker, and more comprehensive network service for users, and to bring more convenience for the development of the SP/CP(Service Provider/Content Provider), we propose an open service system whose architecture and the standardization of the open API(Application Programming Interface) are discussed more in this paper. To design such a system, Firstly, the common services model,...
Evaluate power transformer's operating status correctly is a key issue to its reliable working and the maintenance policy. The Health Index (HI) represents a practical tool that provides the overall health of the asset, among which reasonably determine the weight of each index is the key to guarantee the quality evaluation. While in the current weight determination process, the method of professor's...
The performance of traditional TCP congestion control protocol degrades when congestion and contention increase in ad hoc networks that use the IEEE 802.11 DCF. Many of the problems result from medium contention at the media access control (MAC) layer. In this paper, we present a new contention-based congestion control (CBCC) method according to a novel congestion information from MAC layer. This...
Engineering asset management (EAM) process is a broad discipline and the EAM functions and processes are characterized by its distributed nature. However, engineering asset nowadays mostly relies on self-maintained experiential rule-bases and periodic maintenance, which is lacking a collaborative engineering approach. To enrich the maintenance efficiency and customer relationship, this research proposes...
