Blind recognition of error correcting code over GF (2) have been studied intensively in past few years, however, few works have been involved the case of non-binary codes. In order to approach the problem, a novel method for blind recognition of Reed-Solomon (RS) codes is proposed in this paper, which is based on Galois Field Fourier Transform of code polynomial. Moreover, theoretical analysis of...
Low voltage switchgear compartments are widely used in power distribution networks, and the temperature-rise is strictly limited by IEC 60439-1. Considering the contact resistance, eddy current and thermal flow, an electromagnetic-thermal-fluid coupled model is developed to predict the temperature-rise of a low voltage switchgear compartment. The circuit breaker in the compartment is simplified into...
Traditional video compression methods remove spatial and temporal redundancy based on the statistical correlation. However the final receptor is the human, we can remove the perception redundancy to get higher compression efficiency, by taking use of the properties of human visual system (HVS). Research has simulated the sensitivity of HVS to luminance contrast and spatial and temporal masking effects...
This paper addresses the problem of linear time-invariant multi-input-multi-output (MIMO) system identification. Specifically, we focus on identifying the finite impulse responses (FIRs) of a MIMO system. Observing that the FIRs are often approximately sparse, namely containing many near-zero elements, this paper proposes to use the ℓ1 regularized least squares (ℓ1-LS) method as the estimator. Comparing...
To identify the fittest quantity for every higher education resources in Heilongjiang province, a surface model is constructed based on collected data in 20 years, 15 vectors and the corresponding multinomial equation. Firstly, the vectors are integrated to human capital, material capital, intellectual capital and intangible capital, which have been reconstructed from the original data. Considering...
This paper shows a strategy for the fuzzy logic control system using an offline simulated ball mill grinding approach. In this study, a step change in the force reference signal is considered a disturbance. The current study focuses on the design and implementation of a fuzzy logic control system for product flow rate of ball mill grinding process. The performance of the system is analyzed by simulating...
In this paper we firstly construct the category CRPOSRep with objects the same as CRPOSR (with as objects R-complete R-posets where R-limits preserve orders of approximating order family and as morphisms R-continuous mappings) and as morphisms e-p pairs. Secondly omega-chains, R-chains and R-completeness are defined in CRPOSRep. They are generalizations of omega-chains and omega-completeness in...
An automotive active suspension system composes of a mechanical structure and a feedback controller. Conventionally, these two elements are designed sequentially, with the controller design subsequent to that of the mechanical structure design. The traditional design method cannot obtain the global optimum performances for the system. This paper presents an approach to integrate structural and control...
Linear auto-regression moving average with extra input (ARMAX) model for air temperature system in a naturally ventilated greenhouse was developed. Outside air temperature, relative humidity, global solar radiation and wind speed were used as disturbing input variables of the model, while inside temperature was used as output variable of the model. Based on energy and mass flows equations, statistic...
