Increasing emphasis in data protection legislation on the provision of user consent and privacy protection poses a challenge to automated Cloud Computing applications.. Here, the infrastructure is removed from the user and therefore no direct link for consent or user control exists. In such environments assurance and best effort from the Cloud Provider to carry out the users wishes and protect his...
This paper presents a hardware architecture for H.264 intra prediction frame processing. This design reuse some modules according to the common parts of luma 16×16 prediction and chroma 8×8 prediction in architecture and algorithm. Thereby reduces the area of chip and cost, and enhances its market competition. The parallel pipeline is also adopted to enhance the encode efficiency. The top-down design...
Load testing is an important phase in the software development process. It is very time consuming but there is usually little time for it. As a solution to the tight testing schedule, software companies automate their testing procedures. However, existing automation only reduces the time required to run load tests. The analysis of the test results is still performed manually. A typical load test outputs...
The principles of risk management have been introduced in grid computing to help document and anticipate certain risks and manage them to ensure job executions are successful. Clouds are more complex environments with further concerns like risk, trust, eco-efficiency, green, security or cost. In this paper we present ongoing research work to analyze and address the risk factor in clouds with the aim...
In this paper, we discuss the bit-interleaved coded modulation (BICM) for the half-duplex decode-and-forward (DF) relay network based on the protograph LDPC codes. The half-duplex relay BICM design problem can be transformed into a problem of rate-compatible BICM design, where the different segments of modulated symbols experience different SNRs. To optimize the BICM based on the rate-compatible protograph...
A great deal of research in software engineering focuses on understanding the dynamic nature of software systems. Such research makes use of automated instrumentation and profiling techniques after fact, i.e., without considering domain knowledge. In this paper, we turn our attention to another source of dynamic information, i.e., the Communicated Information (CI) about the execution of a software...
Based on the working mechanism of the speed controlling system on the diesel engine, the control program of the diesel engine speed controlling system was built using the FNN-GA syncretic theory, control strategy of the diesel engine speed controlling system combined the fuzzy neural network (FNN) and the Genetic Algorithm (GA) was developed, the fuzzy reasoning logic and the dynamic simulation model...
In the paper, takes high college and university in Jiangxi province as an example, based on the survey in the targeted high college and university and systematic analysis on the high college and university actual situation, with the help of the literature review, research methodology and analytical framework of the competitiveness, the paper established the eight influencing factors that acted on...
The backbone of cloud computing platforms like Amazon S3 and Salesforce is formed by Ultra-Large-Scale (ULS) systems, i.e., complex, globally distributed infrastructure consisting of heterogeneous sets of software and hardware nodes. To ensure that a ULS system can scale to handle increasing service demand, it is important to understand the system's performance behaviour, for example to pro-actively...
In a typical wireless communication environment, radio channels need to be estimated for systems employing coherent detection. For implementation simplicity, Pilot-Assisted Channel Estimation (PACE) techniques have been widely used. An efficient interpolation method helps to estimate the channel fading coefficients between consecutive pilots with minimised pilot overhead. The simple linear interpolation...
LDPC codes are very powerful error correction codes for Bit-interleaved coded modulation with iterative decoding (BICM-ID) scheme. In this paper, an improved extrinsic information feedback algorithm based on Gaussian approximation is investigated for LDPC coded BICM-ID system. This method can alleviate the correlation of extrinsic information during iterative processing and thus make the extrinsic...
A novel Ca-based sorbent was developed to removal SO2 and NO from flue gas simultaneously. CaO and the fly ash with a mass ratio of 1:4 were hydrated at ambient temperature to make the basic sorbent. NaClO2 and KMnO4 were used as oxidants adding to the basic sorbent to enhance the sorbent ability for SO2/NO capture. The effects of influencing factors on the SO2/NO capturing capacity of the Ca-based...
By reconstructing an attenuation function of the original function, modifying the convergent factor, and analyzing the characteristics of convergence factors changes, the numerical filtering algorithm of the inverse Laplace is improved, obtaining the improved algorithm for the numerical filtering algorithm of inverse Laplace transform, which makes the scope of application with the original algorithm...
In today's global economic integration, the competition of enterprises is the competition of talents. Today is also the era of knowledge economy, the management enterprises is the management of culture and talents. Human resources management (HRM) has a vital role in the development of enterprises. In the HRM of enterprises, enterprise culture should serve as the spirit guidance. Managers should improve...
Riparian buffer strip plays an important role in preventing agricultural non-point pollution and protecting river quality. Purification effect of nitrogen and phosphorus in Nongjiang river was studied by selection of a typical sampling transect, five sampling sites were selected along the sampling transect. Every two neighbouring sampling sites formed a buffer substrip and four buffer substrips were...
This work addressed the Land Surface Emissivity (LSE) retrieval over west China region from combined Middle InfraRed (MIR) and Thermal InfraRed (TIR) data of the Stretched Visible and Infrared Spin Scan Radiometer (SVISSR) aboard the Chinese first generation geostationary satellites FengYun-2C (FY-2C) and FengYun-2D (FY-2D). To improve the retrieval accuracy, the SVISSR/FY-2 infrared channels 1 (∼10...
We present the development of an 8-channel X-band microstrip phased array receiver with beam-scan capability of +/−45 degrees in the azimuth plane. Two 0.13 µm CMOS RFIC chips are integrated directly on the laminates for the array feed network, with each chip comprising of a 4-way power combiner network and 4 channels of RF front-end. Each RF-front-end consists of an LNA, a VGA and a phase shifter,...
The design of benchmark imagery for validation of image annotation algorithms is considered. Emphasis is placed on imagery that contains industrial facilities, such as chemical refineries. An application-level facility ontology is used as a means to define salient objects in the benchmark imagery. In-strinsic and extrinsic scene factors important for comprehensive validation are listed, and variability...
According to the characteristic analysis of the LiFePO4 Li-ion battery, and aiming at the real-time identification of the model parameter, the battery model was established based on PNGV. The real-time identification of PNGV model parameter was achieved by fading memory delivery recursive least squares.

Six standard analytic coarse alignment methods and a direct method are compared via error analyses for strapdown inertial navigation system on stationary base. Although these methods are derived from the same measurements of the local gravity vector and the Earth rate, their error characteristics are not completely identical. The susceptibility of these methods to geographical latitude is examined,...
