Real estate industry has become a pillar industry of the national economy. Enhancing estate enterprise management must improve the financial management level of real estate enterprise. According to the main problems of real estate enterprise financial management, enhancing financial management informatization of real estate enterprise is discussed in this paper in order to improve the competitiveness...
This study proposes matrix-MCE (MMCE) to reduce the influence of noises. Background noises usually degrade the performance of speech recognition. MMCE can efficiently minimize the classification error of two-dimension-cepstrum (TDC). Then the template matching employs the Gaussian-mixture-model (GMM). To evaluate the performance, the speech data used for our experiments are a set of isolated Mandarin...
This paper presents the design of two compact dual-mode open-loop microstrip filters, and their comparisons are described. In design, the dual-mode resonator is used as a doubly tuned resonant circuit, so the dimension of filter is reduced by half and compact configuration is achieved. The dimension of fabricated filter is 1.84 cm*1.84 cm on substrate with dielectric constant of 10. The measured results...
Radio-frequency (RF) tissue fusion means sealing tissue between a knife and an electrode (monoploar) or two electrodes (biopolar) delivering RF currents. Even the mechanism of adhesion is poorly understood, RF modification is correlated to thermal damage. In this paper, a multimodal monitoring system with Aluminum-doped Zinc-Oxide (AZO) thin films glass as electrode is proposed and chicken bowel is...
Differentiating pathological stages, i.e., hyperplastic (H), tubular adenoma (Ta), tubulovillous adenoma (Va) and adenocarcinoma (A), of detected colon lesions is a main task for computer aided diagnosis (CADx) of polyps for computed tomography colonography (CTC). In this paper, we propose a virtual pathological model of differentiating the polyp types based on the Haralick texture analysis model,...
Media player plays a very important role in real-time video surveillance. But currently many media players, which are based on DirectX, Flash and ActiveX, have many problems such as installation failure, maintenance cumbrance, security defects and so on. With the rapid development of HTML5 technology, the HTML5 video tag is very excellent for static video files, but currently it is not very suitable...
The perception of Human Visual System (HVS) for the video scene is selective. Different regions in the video scene have distinctive levels of visual importance. In this study, we present a novel H.264 visual perceptual video coding (VPVC) method in a uniform analyzing and encoding framework, which can allocate bit and computation resources effectively. The framework presented in this work consists...
A novel real-time moving object detection scheme in H.264 encoding domain is proposed. This scheme employs the encoding information of motion vectors (MVs) and the sum of absolute differences (SADs) as the input features to reduce the computational complexity, and takes the global motion into consideration for the video scenes with moving backgrounds. First, a fast global motion estimation model and...
In this paper, a digital pre-distortion platform is designed for linearization of wideband power amplifier with nonlinearity and memory effect. The proposed platform consists of digital signal processing (DSP), field-programmable gate array (FPGA), analog to digital converter (ADC) and digital to analog converter (DAC) which are all operating under a high speed of 400MHz. The platform covers a frequency...
Clustering of laser scanner data is a key part of obstacle recognition of automated vehicle with laser scanner by which efficient obstacle determination and fast environment understanding will be achieved through the analysis of the several classes not amounts of data. Traditional clustering methods of laser scanner data based on hard-threshold principle can not meet the requirements of unstructured...
A comparison study on temperature measurement precision between middlewave 3–5μm and longwave 8–12μm measuring thermal imaging systems has been conducted. The study was limited to systems working in indoor conditions and the target's temperature is in the range of 270K∼900K. First, the Disturb Resisting Function (DRF) of infrared systems is deduced. On the base of DRF curve, we find that the middlewave...

Photoelectric theodolite of U type with main visual axis...
Filtering of laser scanner data is important for effective and fast environment recognition of autonomous vehicle in unstructured environment where many uncertainties caused by complex terrain and various obstacles lead to the invalid data existing in laser scanner data. Traditional filtering methods are easy to cause false noise detecting in the complex and changing environment, because not only...
Video popularity ranking is commonly used in various streaming systems. Existing popularity ranking systems usually rank videos from the perspective of access frequency and ignore other implicit feedback, due to the belief that popularity rankings with different implicit metrics are highly consistent. Based on a large collection of real-world system trace data, this paper systematically compares video...
As the booming of EV and renewable energy markets, energy storage has been gaining more and more attention. There are a large variety of energy storage technologies, such as super caps, flywheel, thermal, compressed air, and batteries of different chemistries, including lead acid, lithium ion, flow battery and nickel cadmium. These energy storage devices can be configured into a large variety of power...
