本發明係提供一種在解碼錯誤訂正碼時用以計算徵兆多項式之方法，其係利用徵兆值與錯誤定位器多項式係數之關係可以推論出當前t個徵兆值為零時表示後t個徵兆值亦為零，其中t為最大可更正錯誤數目。對所有接收字碼計算出前t個徵兆值；之後再判斷該前t個徵兆值是否為零，若該前t個徵兆值為零，則停止計算，否則繼續計算後t個徵兆值。因此，本發明只需一半徵兆值之運算量即可判斷接收字碼是否發生錯誤，故可有效降低實際運作上的運算量，並達到低消耗功率之目的。

The growth and transport properties of (110)-oriented La2/3Sr1/3MnO3 thin films on TiO2-buffered silicon substrates by pulsed-laser deposition are reported. An insulator-metal transition associated with a ferromagnetic transition was observed at about 360 K. Magnetic measurements showed that in-plane coercive fields are about 60 Oe and 300 Oe at 300 K and 5 K, respectively. A magnetoresistance with a Deltarho/rho(H = 0) ratio of -20% in a magnetic field of 5 T was observed not only near the insulator-metal transition temperature but also below 30 K. Moreover, a T-2- to T-3-dependence crossover of resistivity was observed around 60 K, indicating that an unconventional one-magnon scattering may have occurred.

Aquifer parameter identification using the extended Kalman filter

[1] An approach using the extended Kalman filter (EKF) and cubic spline is proposed to identify the aquifer parameters in both confined and unconfined aquifer systems. The cubic spline applied to the observation data can generate interpolated data with uniform time intervals and facilitates the implementation of EKF. The EKF combined with the Theis solution or Neuman's model, using the interpolated drawdown data produced by cubic spline, can optimally determine the parameters through the recursive process. The proposed approach can quickly identify the parameters, using only part of observed drawdown data, and the obtained parameters are shown to have good accuracy. Thus length of time of pumping tests may be shortened. Comparisons of results from nonlinear least squares combined with finite difference Newton's method (NLN) and EKF show that the EKF allows a wider range of initial guess values than NLN and have the accuracy of the results on the same order of magnitude as that of NLN. When determining the aquifer parameters, the identification process of specific yield reflects the effect of gravity drainage on the drawdown curve and conforms to the physical nature of an unconfined aquifer. Furthermore, this study shows that EKF can be successfully applied to analyze the drawdown data even with white noises or temporally correlated noises.
Establishment and application of a fluorescent polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method for identifying porcine, caprine, and bovine meats

A method of fluorescent Polymerase Chain Reaction-restriction fragment length polymorphism (PCR-RFLP) was applied as an analytical and quantitative tool for meat identification. Following alignments of the nucleotide sequences, an oligonucleotide primer pair was designed to amplify the partial sequences within the 12S ribosomal RNA (12S rRNA) gene of mitochondrial DNA from porcine, caprine, and bovine meats. No fragment can be amplified from dog, cat, fish, duck, goose, turkey, and chicken DNA with the primer pair. Using fluorescence sensor capillary electrophoresis, the species-specific DNA fingerprints of pork, goat, and beef were generated by restriction enzyme digestion following a fluorescence-labeling PCR amplification. Species identification was conducted on the meat mixtures. The reliably semiquantitative levels were below 1% for binary mixtures of pork, goat, and beef. Cooking and autoclaving of meats did not influence the generation of the PCR-RFLP profiles or the analytical accuracy.

A novel soft-program for a narrow erased state Vt distribution, read disturbance suppression and over-program annihilation in multilevel cell flash memories

In floating gate flash memories, anode hot hole injection induced by the channel FN erase will result in tunnel oxide, degradation, severe read disturbance and an abnormally fast program. All of these issues are critical for multilevel cell (MLC) flash memory design, which requires precise threshold voltage placement, good data retentivity and programming controllability. In this paper, a novel soft-program scheme is proposed to narrow the threshold voltage distribution in the first level. Cycling-induced read disturbance and programming inaccuracy are also reduced. This technique is essential for the application of more-than-2-bit MLC, flash memories.

In this paper, we propose a novel self-alignment vertical thin-film transistor (VTFT) structure with excimer laser annealing (ELA). The ELA on source and drain decreases the process temperature, suppresses the lateral diffusion of dopants in short channel devices and increases the driving current. Furthermore, the VTFTs have high carrier mobility, compared to conventional polysilicon thin film transistors (TFTs).

Process capability indices C-PU and C-PL are developed in the manufacturing industry to provide quantitative measures on process potential and performance. for processes with one-sided specification limits. Statistical properties of the estimators of C-PU and C-PL have been investigated extensively, but only restricted to cases with single samples. In this paper, we consider the estimation and capability testing of C-PU and C-PL based on multiple samples. We show that the proposed estimator of C-PU and C-PL are indeed the uniformly minimum variance unbiased estimators (UMVUEs). A simple procedure based on a hypothesis testing using the UMVUE is developed for the practitioners to use for judging whether a stable process meets the preset capability requirement.

Watermarking approach to embedded signature-based authentication by channel statistics

Embedded signature-based authentication is a highly promising watermarking method for solving high-level authentication problems. This work proposes such a watermarking approach using channel statistics evaluated from a reference watermark. The basic concept is to consider the problem to be an example of communications with side information, which is the reference watermark embedded in the host with the signature at the sender site. At the receiver site, the reference watermark is first extracted to determine channel statistics, which are used to generate information about signature reliability. Three kinds of information are derived, including a reliability measure, an entropy measure, and an authenticated signature. Experimental results establish that the measures of reliability and uncertainty are meaningful, and that the embedded signature can survive high-quality JPEG compression and manipulations such as negation, cropping, replacement, and modification.

Brownian dynamics simulations of the effects of hydrodynamic interactions on the polymer viscoelastic behavior

Brownian dynamics simulation is used to investigate the viscoelastic response of the Gaussian chain to a step shear deformation in both the linear and non-linear regions under the influence of hydrodynamic interactions. Both the preaveraged Oseen tensor and the Rotne-Prager tensor are used in the study. In the former case, the simulation results are shown to be in agreement with the expected results calculated using the eigenvalues of the normal modes of motion obtained numerically. It is shown that an initial state with zero second normal-stress difference is generated by the step shear deformation. The subsequent rise of the second normal-stress difference as revealed by the simulation is shown mainly arising from the coupling of the recoil of the stretched bond in the direction of deformation and the anisotropy in the hydrodynamic interaction created by the step deformation.

The thermal properties and hydrogen bonding behavior of B-a type polybenzoxazine (PBZZ)/PVP blends were investigated by DSC and FIFIR. The DSC result shows a single T-g over the entire compositions and a large positive deviation based on Kwei equation was observed in the T-g versus composition diagram, implying that strong hydrogen bonding interaction exists between PBZZ and PVP segments. The strength of hydrogen bonding interaction is in the order of inter-association between the hydroxyl group of PBZZ and the carbonyl group of PVP (K-A = 594 L mol(-1)) > self-association between the hydroxyl group of pure PBZZ (K-B = 72.6 L mol(-1)) > inter-association between the hydroxyl and the Mannich-based bridge of pure PBZZ (K-C < 10 L mol(-1)). Good correlation between DSC and FIFIR analysis were observed. (C) 2003 Elsevier Science Ltd. All rights reserved.
