Channel equalizer is a key component of WSN-OFDM (Wireless Sensor Networks Orthogonal Frequency Division Multiplexing) system. Traditional equalizer is mostly designed with LS algorithm, which comes with low precision in channel estimation. The previous LMMSE algorithm could reach a high accuracy, but...

Flame retardant and mechanical properties of ammonium polyphosphate (APP), melamine phosphate (MP) and their combination with dipentaerythritol (DPER) in styrene-butadiene-styrene rubber (SBS) were studied. The results indicate that MP is more effective in raising limiting oxygen index (LOI) in SBS than...

Computational methods for predicting the new drug-target interactions are more efficient that those experimental methods. Many machine learning based methods have been proposed but most of them suffer from false negative problem. In this paper we extend the original label matrix and adopt weighted lose...

Online learning is a learning way to use online education platform for learners. It could let the learners start learning at anytime from anywhere by removing the traditional education's time and space limit. As the online learning style becomes more and more popular, its main base environment has gradually...

Perovskite-type cube structure LaMnO3 nanofibers of approximately 50~100 nm in diameter were synthesized via Sol-Gel processing and electrospinning technology after calcined at 900 by using polyvinypyrrolidone (10 wt %PVP) as complexing agents. The nanofibers was characterized by means of scanning electron...

The sedimentary facies characteristics has been investigated based on the core examination, logging facies analysis and seismic interpretation, Eight types of microfacies grouped into three subfacies associations are recognized in the Chang 7 reservoir. Braided delta front subfacies is rich-sand deposits...

A method to evaluate fluctuation characteristics of daily solar irradiance was introduced based on theoretical solar irradiance. Process feature of daily solar irradiance were analyzed. Observed daily solar irradiance of 10 days in Beijing was tested to demonstrate the effectiveness of this method. Result...

The compatibility, stability and the pyrolysis behavior of aluminum based solid-liquid compound fuel were systematically investigated by thermogravimetric analysis (TGA). The compound fuel lost its 30% weight before the temperature rose to 150 . AP decomposed at 210 and lead to 50% weight loss. The reaction...

How UI designers and business engineers collaborate to development apps on Android platform conveniently and effectively is a difficult problem to tackle when projects get more complicate and need more effort. This paper compared the commonality and variability of MVVM with the commonly used MVC and...

In MapReduce environment, problem of data redundancy,a large number of tasks to be processing and mass data storage come up, in order to solve these problems, we put forward the way of data prefetching , preprocessing of hid the remote data access latency, by adjusting the allocation of resources to...

The implementation of “the equatorial principle” in commercial banks is of great significance for reducing the risk of project financing, fulfilling corporate social responsibility and realizing the sustainable development of society, economy and environment. This study examined the performance of commercial...

This paper mainly studies the effects of monthly production of iron and steel in eight cities in Hebei on the air quality of Beijing and Tianjin. First, this paper uses 10 cities to study whether iron and steel production has an impact on air quality, and the conclusion is that iron and steel production...

Under the background of the less connection between teachers and students in universities and the rapid development of the Internet, and according to the needs of students and teachers, the topic was to design and develop university research and academic platform prototype based on Android. First of...

Generalized Lloyd Algorithm(GLA) is important in vector quantizer design. It runs fast, but it is sensitive to initial conditions and it may find a local optimum. We propose an improved approach based on GLA, named vector quantized codebook reorganization algorithm (VQCRA). VQCRA finds better codebooks...

A link in production network is usually a creditor-debtor relationship. If a firm goes into financial insolvency state or bankruptcy, then firms on its upstream can have secondary effect from the bankruptcy. By using the recent 10 years data of bankruptcy in japan, we show that these causes of ``link...
