The sensor modeling problem of electrical capacitance tomography (ECT) is to establish the functional relationship between normalized capacitance values and normalized permittivity distributions. Three different sensor modeling methods are presented in this paper, that is, the sensitivity definition (SD)method, the electric field strength (EFS) method and the multiple linear regression (MLR) method...
This paper proposes a new symbol-based near maximum likelihood (ML) detection scheme for multiple-input multiple-output (MIMO) systems. The proposed scheme can provide not only near ML performance with low complexity but also the capability of unequal error protection (UEP), i.e., data from different antennas can have different reliability. Compared to the conventional symbol-based near ML detection...
This paper presents a new workforce allocation optimization model for project scheduling problems with multi-skilled workforce constraints (PSPMSWC), under uncertainty about the projects. The model is a mixed-integer program(MIP) model that aims at maximizing the total profit. As a subproblem, scheduling and staff assignment for projects must also be optimized. In the experiment, projects are selected...
Sequence analysis of D1/D2 region of 26S rDNA was used for identification of different yeasts isolated from food-borne material. Then, their aromas compounds were detected and analyzed by SPME-GC-MS, another biology information technology. 12 yeast strains were grouped in 7 species belonging to 5 genera as follows: Saccharomyces cerevisiae, Torulaspora delbrueckii, Kluyveromyces marxianus, Pichia...
Blind carrier frequency offset (CFO) estimation algorithms in orthogonal frequency division multiple access (OFDMA) systems have been developed in literatures recently. In [1], the blind estimation scheme has drawn a lot of attention, but the mismatch problem may occur, where the estimation error is out of range. In this work, we utilize the Markov chain Monte Carlo (MCMC) method based on a Bayesian...
Blind carrier frequency offset (CFO) estimation algorithms in orthogonal frequency division multiple access (OFDMA) systems have been discussed in the literature recently. In [1], the blind estimation scheme has drawn a lot of attention, but the computational complexity caused by the MUSIC exhaustive search is high. Therefore, an iterative scheme is proposed in this paper to reduce the computational...
