The recommendation system based on collaborative filtering is one of the most popular recommendation mechanism. However, with the continuous expansion of the system, several problems that traditional collaborative filtering recommendation algorithm (CF) faced such as speedup, and scalability are worsen. In order to address these issues, a parallel collaborative filtering recommendation model based...
With the development of simulation applications, the Distributed Simulation Resource Repository (DSRR) could manage all kinds of distributed simulation resources and provide transparent access, search, and browsing for users. In recent years, more and more research focus on the construction of DSRR, which includes metadata, dataset, algorithm, model, toolkit, and etc. However, when more and more resources...
Cluster supply chain is a complicated network structure, the enterprises in it not only have to coordinate with enterprises in the same single chain, but also have to compete and cooperate across chain. In this paper we study mainly on how core manufacturers in different single chains cooperate and compete with each other, in order to realize the minimal cost under the premise of cluster supply chainpsilas...
In this paper, firstly we introduces the subsystems of the tax management information system. Then we establish the layer framework of tax management information system, including page framework, application framework and data framework. The tax management information system can improve the taxation service, reduce the taxation cost, and provide reliable reference for macro-economic decisions.
It is an ideal choice of establishing the simulation of the Automatic Storage&Retrieval System (AS/RS) for predicting cost and increasing efficiency. In this paper, Flexsim is used to build up an AS/RS system model for simulation and optimization. Firstly, the overall process and simulation modeling are described in detail based on Flexsim. During analysis of the model, this paper focuses on the...
In this paper, firstly we introduces the main content and operation flow of the tax management information system as well as main functions of its subsystems. Then we describe the general structure and technical implementation strategy of the application system. The tax management information system can improve the taxation service, reduce the taxation cost, and provide reliable reference for macro-economic...
This paper demonstrates the linkage between logistics system simulation and teaching mode, and explores new teaching methods and teaching ideas. It puts emphasis on analyzing the application of logistics simulation technology in the logistics system and exploring appropriate teaching modes of logistics system simulation. We make a point of the application of logistics system theory knowledge and the...
A compact Ka-band transceiver module with two channels has been developed. This transceiver module consists of two DRO resources, E-plane waveguide filter, coupler, power dividers, over 200 components and 15 MMICs which conclude one mixers, one frequency multiplier, one low noise amplifier, five amplifiers and seven switches, and has superior performance of switch rise-time and fall-time less than...
This paper deals with an embedded multilayer LTCC interdigital bandpass filter. This compact filter is used in LTCC transceiver module to suppress the unnecessary frequency components in LO branch. According to validation, measured results are in good agreement with simulated results. The passband insertion loss and stopband suppression at concerned frequency points accomplishes suppression desires...
