In this paper, a pilot contact oxidation system was used to different mixing ratio wastewater of slaughterhouse wastewater and biogas slurry. The results showed that when the mixing ratio of slaughterhouse wastewater and biogas slurry was 19:1 and the HRT of the system was 24h, the COD of effluent met the discharge standard in winter. While when the mixing ratio was 4:1~2:1, the effluent exceeded...
In previous work we developed a support vector machine (SVM) approach for detection of microcalcifications (MCs) in mammogram images, which was demonstrated to outperform several existing methods for MC detection in the literature. In this work, we explore whether we can further improve the performance of the SVM detector by exploiting the fact that MCs are inherently invariant to their spatial orientation...
VSM (Vector Space Model) is one of the important methods for describing documents. However, in the process of information representation, features are always high dimensional. So feature extraction technologies have to be used to reduce dimensions. At present, there are lots of feature extraction algorithms, in which TF-IDF,TF-IDF-IG are used widely in practice. However, as the two didn't consider...
In this paper, we developed a thermal actuated lateral RF MEMS capacitive switch using the HfO2 film as sidewall isolation dielectric based on atomic layer deposition (ALD) process to approve the isolation and reliability. In close state, the HfO2 film provides strong capacitive coupling between the signal line and switching plate, as well as electrical isolation performance between the switching...
Firstly, 2, 204 EST sequences of tree peony were downloaded from the database of NCBI, then redundant sequences were removed and 1,658 non-redundant ESTs were obtained. The results showed that a total of 1,111 SSRs were detected, with the frequency for the non-redundant ESTs being 67.00%. Among the different SSRs motifs, the amounts of repeats sorted as mononucleotide, dinucleotide and trinucleotide...
In order to adapt the change from centralized development pattern to multi-user collaborative development pattern in modern software development, the concept of software collaborative development was proposed by introducing CSCW (computer-supported cooperative work) into the field of software development, and the properties of it was analyzed, then a formalized model SCP-NET of software collaborative...
In recent years, because of adjustment of the social industrial structure, the proportion of services is gradually increasing, which promotes the study of the service supply chain (SSC). On the basis of the existing research in SSC, the types of risk of international freight forwarding in Logistics Service Supply Chain have been described in this paper; Risk Map has been used to make a quantitative...
In this paper, the effects of semi-spherical radome and nose radome enclosed on the characteristics of antenna are investigated in detail by the means of aperture-integration and surface-integration (AI-SI). The AI-SI method is superior to ray tracing when the radome curvature varies significantly. Besides, this algorithm is simply and can be appropriate for any aperture. Calculated far-field patterns...
Stage stunt system is an automatic steeve system orchestrated by PLC. Security and fault-recover are two important properties of the system. In this paper, we analyze and verify the stage stunt system formally. We adopt hybrid automata to model the system. The forward reachability is used to verify the properties on the reachable states. We present a case study to illustrate the feasibility of the...
The use of near infrared spectroscopy (NIRS) to measure the concentration of elements in Irpex lacteus was investigated. One hundred and sixty three samples were collected and traditional methods were used to determine the concentration of adenosine, polysaccharide and mannitol. The spectra were pre-treated by avitzky-golay smoothing, fast fourier transform (FFT), 1st derivative and 2nd derivative...
The Internet has intrigued new treatment modalities in Psychotherapy. E-Psychotherapy utilized the power and convenience of the internet to allow simultaneous (synchronous) and time-delayed (asynchronous) psychological therapy between individuals and professionals. The term e-psychotherapy defined as professional mental health care service via the Internet technology, such as e-mail, chat technology,...
As the rapid development of the Mobile Internet (MI) applications, the Mobile Internet Services (MIS) are becoming the focus of development in the future. This paper focuses on the security issues of MIS, and puts forward the security framework for MIS. This framework is based on the existing network security standards, and describes the threats and requirements based on the features of the MIS. It...
During the multi-dimensional Fuzzing technique, how to construct the influencing relationships between input elements and vulnerable statements is a key problem. This paper applies the virtual machine based taint analysis technique on multi-dimensional Fuzzing, gives detailed design and the experiment result shows the method is feasible.
In this paper, a new measure of correlation is introduced in undirected network. In order to get accurately degree distribution for the vertex at the end of a randomly chosen edge, we considered the information of edge, rather than just the degree distribution of node. We analysis the Enron Email Network with the three measures via degree-degree correlation, and get more information than the traditional...
In recent years, software vulnerabilities are one of the main causes of security incidents in computer systems. Dynamic taint analysis is an efficient method to track the flow of sensitive information for soft vulnerability mining. In this paper, we present the method for dynamic taint analysis with control dependent is to tracking sensitive information. And finally, the simulation results are proposed...
Digital watermarking is an efficient method to protect multimedia documents. Robust watermarks, which survive to any change or alteration of the protected documents, are typically used for copyright protection. Fragile watermarks, which are vulnerable to a little alteration, are typically used for content authentication. In the paper, we propose a hybrid watermarking method joining a robust and a...
In this work, an activator system used for no-rosin lead-free solder paste was prepared by compounding with 5-Sulposalicylic acid dehydrate and an organic which restrains the over-quick release of the activator. The composition of the active system was studied by thermal gravimetric analysis. Additional, characterizations of the solder paste with various formula such as viscosity, wettability and...
QoS routing protocol has become a hot research spot. However, it is difficult to offer guaranteed QoS, such as bandwidth, delay and delay jitter. To solve this problem, we proposed a Delay-Minimized Routing protocol based on Bandwidth Estimation (DMR-BE) that incorporates an admission control scheme and a route decision scheme to meet the QoS requirement of bandwidth and real-time applications. Bandwidth...
Location-based service (LBS) is value-added service, which can provide the user corresponding service by obtaining the location information of the user's mobile terminal, with the help of mobile telecom operators' radio communication network or external positioning method. In this paper, we design and implement a Location-based camera system (LBCS) on Samsung Bada smart phone platform. LBCS can indicate...
Smart home has become a popular application all over the world. However, the service to interact with smart grid, and the service to guide residents utilize power, are ignored. In this paper, we propose an effective convergence service oriented architecture to give a solution for supplying a convergence service in smart homes. This architecture not only supports diversified service integrated with...
