Hot‐dip galvanizing dual phase steel DP600 steel grade with low Si was produced by steel plant andexperiments by simulating galvanizing thermal history. The microstructure was observed andanalyzed by scanning electron microscopy (SEM)and transmission electron microscopy (TEM). The effect of different annealing temperatures on the microstructure and mechanical properties of dual‐phase steel was also...
Unbalanced energy consumption in heterogeneous wireless sensor networks (HWSNs) results in the “energy-hole” problem. In this paper, a novel Energy-Balanced Unequal Clustering Protocol (EBUCP) is proposed to address the energy-hole problem. In EBUCP, three kinds of sensor nodes named normal nodes, advanced nodes and super nodes are deployed in a circular region which is divided into multilayer rings...
Multiple Cloud services can be composed as a single service to fulfill the execution of large-scale workflow application. It faces trade-offs among several QoS metrics causing by users' preferences. Most existing works utilize multi-objective evolutionary algorithms to address this problem. However, it is hardly to express different users' preferences. This paper proposes an evolutionary algorithm...
We propose and experimentally demonstrate a simple photonic approach to achieving tunable and reconfigurable bandpass microwave photonic filters (MPFs) based on cascaded microring resonators (CMRRs). The optical spectrum of the silicon CMRRs could offer two bandpass responses to separately filter the optical carrier and one of the sidebands generated by the phase modulation. Thus we could achieve...
Glial cell line-derived neurotrophic factor (GDNF) is a potent agent for treating Parkinson's disease (PD). Microbubbles (MBs) have been exploited as a carrier for GDNF delivery with focused ultrasound (FUS) destruction. However, GDNF supplementation only relieves PD symptoms rather than cure it. Thus, design of an endogenous GDNF generative mechanism is an urgent concern for novel PD treatment. Here,...
The current mobile network has been developed to a heterogeneous network that is coexistence of different wireless networks such as UMTS (3G), WIFI, WIMAX (4G) and LTE (4G). Since the demand of realtime multimedia services has significantly increased in recent years and Quality of Experience (QoE) becomes more and more important to users, any single wireless network is hardly to maintain good QoE...
Focused ultrasound (FUS) exposure with the presence of microbubbles has shown its promise in temporally and targeted open the blood-brain barrier (BBB), and brings potential in delivering therapeutic agents into the brain for CNS disease treatment. Feasibility in using neuronavigation system to guide the FUS-BBB procedure in large animals has been demonstrated successfully, and the guidance precision...
Block-based Discrete Cosine Transform (BDCT) image compression method inevitably produces annoying blocking artifacts in the case of low-bit-rate compression, as each block is transformed and quantized independently. Blocking artifacts not only seriously affect the subjective image quality, but also affect the performance of automatic analysis. In this paper, we propose a pre-classified sparse representation...
In order to improve the accuracy and efficiency of rotation invariant texture classification, we develop a novel classification method based on gray-level co-occurrence matrix and discrete wavelet transform in the paper. The method combines the probability of specific neighboring resolution cell pairs occurred at the same time in the whole image and statistics features in wavelet domain. Discrete...
With the rapid development of information technology and the Internet, resulting in a large number of moving object location data, the application of moving object location service is also expanding, such as GPS positioning, the car navigation, position sensor, search and rescue system. More and more location data is being collected, published and used, which may contain the moving object privacy...
Cloud computing as a widely used computing platform can provide a number of services for customers in a pay-as-you-go fashion. Enabling further growing and complex needs of users, service of different independent cloud provider should be composed to deliver uniform Quality of Service (QoS) as a single request. An open and valid question is how to select services as a partner chain and optimize the...
The content of the e-book consists of three units: performance and directing section, technique section, and administration section. Each unit consists of sub-units. The performance and directing section is divided into directing, acting, and rehearsal. The technique section is divided into stage, stage lighting, costume, stage prop, multimedia design, and music. The administration section is composed...
For synthetic aperture radar(SAR) imaging of ship targets, it's difficult to generate high quality images because their motion characteristics are blind in most cases. Aiming at this problem, this paper presents a processing scheme for estimating the radial velocity based on the digital spotlight processing. This method is implemented after the coarse-resolution wide area image is obtained. Then the...
Focused ultrasound (FUS) has been discovered its utility in targeted increase blood-to-brain permeability in the brain and capable of enhancing drug delivery for CNS disease treatment. To achieve successful treatment, the overall FUS exposure process relies on employing a sophisticated treatment planning procedure to precisely target the ultrasound energy to the aim and compensate the skull-induced...
Users always wait to be served by Web service in the community. The cost of Web service community is increased due to the users queue up in the community will consumes resources. In this paper we research on setting optional number of Web services in the community in order to make the cost of community be minimum. A solution was proposed based on both theory of queue and marginal analysis method....
Community of Web Service is a society composed by a number of functionally identical Web Services. The communities are regarded as a whole for users in an opening environment and users would pay for services when they invoke Web Service successfully. Communities should distribute the whole profit to all of the providers of Web Services inside after a settlement period. Due to the cooperation among...
Recently, Dynamic Adaptive Streaming over HTTP (DASH) has been widely deployed over the Internet. Under time-varying network conditions, it is, however, still a big challenge to provide smooth video bit-rate with high video quality, especially when multiple clients compete for the network resources where the fairness must be considered. In this paper, a fairness-aware smooth rate adaptation approach...
Local Binary Patterns (LBP) are among the most computationally efficient amongst high-performance texture features. However, LBP is very sensitive to image noise and is unable to capture macrostructure information. To best address these disadvantages, in this paper we introduce a novel descriptor for texture classification, the Median Robust Extended Local Binary Pattern (MRELBP). In contrast to traditional...
A large-scale data processing is increasingly leveraging Map Reduce frameworks on Cloud computing platform. We aimed to study various job schedulers improved in Map Reduce, and identify research directions in this area. In this paper, the related techniques of Map Reduce and Hodoop are described briefly. Then a variety of Map Reduce schedulers are reviewed and classified, also the features of these...
Open and dynamic environments lead to inherent uncertainty of Web service QoS (Quality of Service). Thus, the Web service composition which consists of these services will be necessarily random of the QoS. The requirements of the QoS of Web service composition may not be certainly satisfied. We use a simulation approach named Importance Sampling to analyze the QoS probability of Web service composition...
