Spectral awareness is currently one of the most challenging problems in CR designer. Recent researches in this area have suggested that cyclostationary approach is proposed as an effective method to solve the detection and estimation in spectral awareness. The drawback of this theory is its complexity of digital implementation. This paper specializes four realizations, namely, SSCA algorithm, FAM...
The dynamic behavior of the rotor-bearing system of the slider-crank mechanism was studied in this paper. Based on the finite element method, a model of the rotor-bearing system was developed. The calculation results of the numerical simulation demonstrated that dynamic response of the shaft depended on both the bearing stiffness and the dynamic property of the slider-crank such as rotor rotate speed.
This paper described a new flicker test standard developed in National Institute of Metrology (NIM) for the calibration of voltage fluctuation and flicker. It meets the requirement of both flickermeter and flicker source according to the IEC 61000-4-15.
The main objective of the present work is an investigation of the computation methods applicability in a cylindrical sealed space, two different geometry constitute methods are introduced, multi-zone model and fluid dynamic model were discussed. Computation results of the two calculation methods are within err of 15% in radial direction, and has different results in the vertical direction upright...
Harmonic pollution monitoring and control is the key to an accurate estimate of harmonic impedance, and thus an accurate assessment of public connection points of the harmonic emission level. This paper analyzes the link under the star-shaped and triangular three-phase asymmetrical power systems derived established a three-phase unbalanced power system harmonic impedance matrix estimation model. Model...
The main objective of the present work is an investigation of the heat transfer induced by the fire in a cylindrical sealed space. The thermal smoke flow geometry characteristics in cylindrical sealed space were discussed, LES and mixture fraction methods were applied to conduct numerical transient analysis. Computed results has validated the smoke flow course in simulation experiments. The study...
This paper has discussed the fire-induced smoke flow geometry characteristics in irregular confined spaces, and use LES and mixture fraction numerically methods to compute the smoke flow in a round cross sectional confined spaces. Computed results has validated the forecast of the flow course, showing that the smoke layer descending faster upper the fire source than other locations. Along with the...
Fusing out-of-sequence information is a problem of growing importance for multi-sensor target tracking systems due to sensors embedded in complicated network architectures. The problem of how to deal with these updates has received much attention in recent years and has been solved optimally and suboptimally by various authors. Most of the solutions treated only the problem of updating a track by...
In this paper, we use evolutionary game theory to build an evolutionary game model for peer inter-enterprise and analyze the evolutionary process and evolutionary stable strategy of implementing defensive competitive intelligence. It shows that when the costs of collecting and protecting invested by the peer inter-enterprises less than the costs of benefits competed by two sides, the long-run equilibrium...
In multisensor target tracking systems measurements from the same target can arrive out of sequence. How to fuse out-of-sequence information is a very important problem for distributed multisensor target tracking systems. Local sensors send their track to a fusion center and then the fusing center uses these track data from one or more sensors to update. In this paper, we obtain the out-of-sequence...
One of the key questions in algebraic attacks is how to effectively reduce the degree of the function. Based on the algebraic attack, this paper presents a new algorithm of attack - chosen IV algebraic attack, which can reduce the function??s degree by choosing appropriate IV. Using this algorithm, we analyze the One.Fivium, the predigesting form of Trivium. we can get 70 key bits, and the length...
In this paper, we present a collaborated architecture using microcontroller, stepping motor and physiological database to obtain the stress measurement of the quizzee. We implement an ergometric equipment for the purpose of iatrical experimentations. This equipment mainly consists of three components: embedded controller, integrator and background database. By regulating the pulse duration of the...
