Wafer level packaging technology, maintaining the same size as the die, is a true chip scale packaging technology offering smallest possible footprint and increased electrical performance. Keeping balance between cost and quality becomes an important point in WLCSP industrial practice. In our work, six kinds of WLCSP samples were designed in order to find out the real reliability contribution of UBM...
In previous geographic information inquiry, query condition is either fixed in program or providing an SQL inquiry mode for users. The former condition is unalterable while the latter demands users to be equipped with certain SQL query language knowledge. The article introduces how to use a rule engine to make inquiries through simple combination between natural semantic modules with the support of...
Feature selection can reduce the feature space dimension and improve recognition. In the discriminatory fresh degree of tomatoes by electronic nose, it used three kinds of feature extraction methods: sheath coefficient characteristics, similitude entropy characteristics and the energy characteristics, and the three methods were compared respectively. The results showed that similitude entropy characteristics...
For control and optimizes the multiple uninhabited combat air vehicle(UCAV) cooperative air-to-ground combat task assignment, the model of UCAV team air-to-ground attack was built firstly based on the variable and constraints. The concept of Distance Discount Factor (DDF) has been introduced to address the fact that targeting close but less significant units could be more rewarding than targeting...
A novel track-to-track association algorithm based on multiple 1-D discrete wavelet transform (DWT) has been proposed. Since the signal and noise exhibit different features in wavelet domain, the ratio of energy in high resolution wavelet space to energy in low resolution scale space is introduced to establish hypothesis test model based on F-distribution. Two test methods have been presented to resolve...
Battle situation fusion assessment system is the core module and preceding function module in combat aircraft air-to-ground attack tactics decision-making system. Bayesian networks have advantages on deal with uncertainty inference. The Bayesian networks models of situation fusion assessment of combat aircraft has been built. The Bayesian inference algorithm and the sensitivity analysis model have...
3D watermarking methods have been proposed to protect the copyright of 3D models. Commonly-used irregular triangle mesh blocks the development of 3D watermarking techniques. In this paper, a novel non-blind 3D watermarking method is proposed based on geometry image, which is a regular 2D grid representation of 3D models. A color image watermarking algorithm in DCT transform domain is applied during...
Summary To investigate a newly developed quinolone antibiotics, the effect of antofloxacin hydrochloride on cytochrome P450 isoforms in rats was examined. A cocktail approach was adopted. Theophylline (CYP1A2), midazolam (CYP3A), chlorzoxazone (CYP2E1), dextromethorphan (CYP2D6), omeprazole (CYP2C19) and diclofenac (CYP2C9) were used as probes in the study, and own control was adopted. In Protocol...
A robust and blind audio watermarking algorithm based on the discrete wavelet transform(DWT)is proposed in this paper as an effective way to resist the malicious de-synchronization attacks. The algorithm embeds the watermark information into the absolute average of audio low frequency coefficients in the DWT and error- correcting coding is applied in order to lower the bit error rate of watermark...
