A mixture of fresh concrete (FC) and demolished blocks (DCBs) with a distinctly larger size about 50 mm~400 mm is called recycled mixed (RMC). In comparison traditional aggregate concrete, RMC has the following advantages: 1) energy consumption associated crushing waste reduced by 40%~60%; 2) cement 30%. Structural members composed steel sections include beams, columns, slabs, walls connections. This paper presents simple review studies conducted authors their group on aforementioned...
The algorithm of discrete wavelet transform and Arnold combined is developed to achieve the integrity authentication color image contents through embedding fragile watermarking. Firstly, a new watermarking generated with XOR between original binary which processed transform. When watermark embedded, converted first brightness component decomposed into three wavelets. Then, low-frequency approximation sub-image third-level extracted, its least significant bit set 0. Finally, embedded bit....
Composed of knowledge acquisition, transfer, application and innovation, customer management's influences on management performance has been the subject numerous studies. But relative empirical results are lacking in regard to how corporate optimization efforts organizational environment will improve its performance. To further investigate impacts supporting factors performance, this paper proposes that a dynamic IT system is key factor, which based management, having customer-orientated...
This paper discussed the definition of fractional Fourier transform(FRFT), basic principles watermark, analysis approach energy distribution, magnitude and other characteristics in Fractional Domain. On this basis, random sequence watermarking algorithm by using Transform was proposed, simulation experiments carried. Experimental results show that has a certain degree robustness on conventional image processing such as JPEG compression, Gaussian low-pass filter. At same time, it can increase...
The confined longitudinal-optical (LO) phonon and surface-optical (SO) modes of a free-standing annular cylindrical quantum dot are derived within the framework dielectric continuum approximation. It is found that there exist two types SO modes: top (TSO) mode side (SSO) in annulus. Numerical calculation on CdS annulus system has been performed. Results reveal different solutions SSO distribute mainly at inner or outer surfaces dispersion relations coupling intensions phonons compared with...
Tree growth in forests is affected independently or jointly by drought dimensions, namely severity, timing, and duration, making the accurate modeling predictions a formidable challenge, it still remains uncertain how trees respond to multiple dimensions of drought. Here, we quantified dynamic response tree (evaluated resistance resilience) different droughts, their determined factors, using tree-ring data 320 birch (Betula platyphylla) from semiarid regions across northern China,...
The final loss function in the deep learning neural network is composed of other functions network. Due to existence a large number non-linear such as activation network, entire model presents nature nonconvex function. As optimizing more difficult, solution can only represent local but not global. BP algorithm an for updating parameters and mainly applied networks. In this article, we will study volume holographic image library technology, design basic optical storage path, realize...
Abstract. In the coming era of big data, high resolution satellite image plays an important role in providing a rich source information for variety applications. Land cover classification is major field remote sensing application. The main task land to divide pixels or regions imagery into several categories according application requirements. Recently, machine interpretation methods including artificial neural network and decision tree are developing rapidly with certain fruits achieved....

Multiple kernel learning methods have a widespread application in visual concept and BoVW method has been widely used dues to its excellent categorization performance. However, most canonical multiple employ stationary combination format which assigns uniform weights over the input space. And aimed resolve problem that time efficiency of decreases as data scales up. As it is true for human perception, from multi-modalities become an effective scheme various information retrieval problems. In...
Against the background where entrepreneurial economy is replacing managerial economy, study on firms' knowledge management mechanism facing their customers in wider sense becoming key to upgrade these customer competence.Thus, based a conceptual model construction of orientation and competence, this paper studies, an explorative manner, by way empirical firms with high orientation, correlation between competence.The autonomy active competition manifest significant positive correlations its...
