In Jianghan plain, generally more rainfall occurs during the main growth period of cotton. So that it is vulnerable to water-logging damage which affects on cotton's growth and even final output. In order to find an effective way to prevent cotton from severe damage, the test-pit experiment was made in the period of cotton flowering that is fertilizer and the plant growth regulator applied to its...
In south China, water logging occurs frequently in spring and summer which generally affect crops' normal growth and final output, so it is important for agricultural production to effectively prevent water logging damage. A test-pit experiment was made in the period of cotton flowering that nutrient regulators were applied to cotton growth recovery aiming at its plants under water logging for 10...
In order to find the effective measures to prevent and mitigate the wet damage of wheat, the rational application of plant growth regulator and foliar fertilizer were necessary. According to the severe water logging disaster of wheat at booting stage, the test-pits were used to build the case of water logging for 8 days to carry out the tests of the different combinations process during and after...
Analysis of cryptographic algorithms is becoming more and more important in information security and malware analysis community. In this paper we have studied the static and dynamic characters of cryptography algorithms in program application by reversing a great lot of samples, and have summarized the static characters as crypto constants, lots of bit wise and arithmetic, logical expression, leaf...
Recently, it has been reported that context-dependent deep neural network (DNN) has achieved some unprecedented gains in many challenging ASR tasks, including the well-known Switchboard task. In this paper, we first investigate DNN for several large vocabulary speech recognition tasks. Our results have confirmed that DNN can consistently achieve about 25–30% relative error reduction over the best...
The subject of the paper is the integration of multi-stream features in the framework of hybrid artificial neural network (ANN) - hidden Markov model (HMM). We investigate the use of log filter bank and MFCC features in multi-stream combination for phoneme recognition. An intermediate integration method is proposed to fuse the information from different sets of features. By exploiting deep learning...
The hybrid model, context-dependent deep neural network hidden Markov models (CD-DNN-HMMs), has received significant improvements on various challenging large vocabulary continuous speech recognition (LVCSR) tasks just in these few years. Recently, it is further reported that gains of DNN are almost entirely attributed to using features concatenated from consecutive speech frames as DNN's inputs....
A low power interface circuit for multisensory system is presented in this paper. A SAR capacitance-to-digital converter (CDC) and a SAR analog-to-digital converter (ADC) are combined together so that capacitance or voltage from different sensors can be measured by the same circuit and converted to digital signal directly. A dynamic comparator with self-calibration is designed to achieve zero-static...
Surface dielectric barrier discharges excited by high nanosecond voltage pulses are a promising approach for producing plasma required by airflow control. Charge transport is an important parameter of discharge characteristics, and the discharge energy can be obtained using an electric charge — gap voltage (Q-V) Lissajous figure. Based on a repetitive nanosecond-pulse generator, the characteristics...
Convolutional Neural Networks (CNN) have showed success in achieving translation invariance for many image processing tasks. The success is largely attributed to the use of local filtering and max-pooling in the CNN architecture. In this paper, we propose to apply CNN to speech recognition within the framework of hybrid NN-HMM model. We propose to use local filtering and max-pooling in frequency domain...
Credit risk is not only the most important and oldest form of risk in the financial markets, but also the most decisive financial risk in the face of the economic subjects in the current market environment. It directly affects all aspects of modern economic, and also a country's macroeconomic policy-making and economic development, and it even affects the stability and coordination of the global economic...
With the development of automotive industry, the number of automobiles in use increases gradually. How to recycle discarded automobile products becomes a problem that will block the sustainable development of automobile industry and will impact environment. Life Cycle Engineering Design is a effective method to solve this problem. Recycling stage of automotive products is a core phase of their life...
We studied the influence of external electric field on two-wave mixing feature in a Ce: KNSBN crystal using a non-simultaneous readout device on the best writing conditions (with best polarization of writing beam). The effective gain and diffraction efficiency of two-wave mixing increased as well as the response time decreased as positive electric field increased applied along the c-axis of the crystal...

In this paper, we present a new approach to enhance noisy speech based on an environmental model incorporating the phase between noise and clean speech (often called phase-sensitive model) in log power spectral domain. Some previous phase-sensitive methods normally assume the phase factor to be a random variable or set it heuristically. In this work, we assume phase to be an unknown parameter that...
A generation method of underwater terrain was brought forward in which the electric chart was used as the data source. Laplace interpolation was used in data interpolation of the water depth on the electronic chart to generate three-dimensional environment. The Roam-based LOD algorithm was improved and data storage structure of the Roam algorithm was redesigned, and a height factor was introduced...
