This paper considers some permutation flow shop scheduling problems with a learning effect on no-idle dominant machines. The objective is to minimize maximum completion time. This objective is considered under following dominant machines constraint: idm, ddm, idm–ddm and ddm–idm. We present a polynomial-time solution algorithm for each of the above cases.
Based on the extensive analysis of shortcomings of traditional policy-based wireless sensor network management methods, in this paper, we proposed the SMART507 framework for automatically generate policies which introduce swarm intelligence into the wireless sensor network management field. We discuss the components of the framework in detail which include(More)
This paper presents the design and study of a digital capacitance measuring circuit with theoretical analysis, numerical simulation, and experimental evaluation. The static and dynamic performances of the capacitance measuring circuit are first defined, including signal-to-noise ratio (SNR), standard deviation, accuracy, linearity, sensitivity, and response(More)
D2D (Device-to-Device) communication is one of the promising technologies in the LTE (Long-Term Evolution)-Advanced communication network From a system perspective, this technology can increase frequency efficiency of the whole macro cell. From the user perspective, a D2D pair which shares the same frequency resource of CUE (Cellular User Equipment), can(More)
An intelligent model of relative words that concerns semantic similarity is discussed in this paper. Based on this model, a knowledge system capable of semantically calculating and associating has been developed, which enables adapting and/or extending keywords in search process. This paper aims to make information retrieval with semantic ability; as a(More)
