Many data center applications have deadline requirements, which pose a requirement of deadline-awareness in network transport. Completing within deadlines is a necessary requirement for flows to be completed. Transport protocols in current data centers try to share the network resources fairly and are deadline-agnostic. Recently several works try to address the problem by making as many flows meet...
Reconstruction, which is the core of compressive sensing (CS), can be implemented by l0 norm minimization. In practice, l0 norm minimization is a NP-hard problem that requires exhaustively listing all possibilities of the original signal and is difficult to achieve by traditional algorithms. This paper proposes a signal reconstruction algorithm combining genetic algorithm with simulated annealing...
In order to implement the guidelines of deep development of civilian-military integration, we need to carry out specific research on the characteristics, basic structure and operation mechanism of civilian-military integration for its industrial innovation platform. The industrial innovation platform of civilian-military integration consists of module suppliers, module integrators, infrastructure,...
Nowadays, with the rapid development of intelligent hardware, the hand gesture interaction is becoming more and more popular in the field of Human-Computer Interaction (HCI). In this paper, we present a dynamic hand gesture recognition algorithm by using our improved Codebook (CB) modeling method and spatial moments. In the pre-processing stage, we train our CB background model with a video of short...
We design a hierarchical collocation extraction tool according to the three-layered linguistic properties of collocation. Based on the structured definitions of collocation, the extraction goes through three phases: i) extracting peripheral collocations in the frequency layer from dependency triples, ii) extracting semi-peripheral collocations in the syntactic layer by association measures (AMs),...
Combined with the distributed control system operating characteristics, this paper proposed a reliability assessment method based on the Markov models. First, determine the assessment of the object and its components, and components formal description. Then we can build the Markov models theory of distributed control system reliability evaluation model, using the model to assess the reliability. At...
The real-time skin deformation of 3D virtual human is one of the hot spots of research fields in 3D virtual human. On the basis of smooth skinning deformation algorithm, this paper proposes a whole body skin deformation method of real-time in motion state, which uses the simple polygon surface model to virtualize the human skin geometry model and uses the bone skin algorithm to drive the skin deformation...
The problem of missing data is frequently encountered in real world applications. In this paper, an attribute weighted fuzzy c-means algorithm for incomplete data sets is presented. The statistical representation proposed in our previous work is used here to impute the missing attribute values, and attribute weighting is involved to emphasize the contribution of important attributes. Experimental...
An Improved Many Worlds Quantum Genetic Algorithm (IMWQGA) was proposed aiming at the shortcomings of the Quantum Genetic Algorithm, such as the multimodal function optimization problems easily falling into the local optimum and vulnerability to premature convergence. Using the concept of Many Worlds and the derivative way of parallel worlds' parallel evolution, we propose to update the population...
In this paper, we focus on how to solve complex traditional game problems with quantum technology. Quantum game prompts the emergence of cooperation by introducing the quantum strategy to traditional game. We analyze three important factors of the evolutionary quantum game on lattice networks: steps, temptation and entanglement. Results of the experimental applications of analysis procedure are given...
In this paper, a corner-truncated artificial magnetic conductor (CT-AMC) reflector backed octagonal-shaped aperture (OSA) antenna is proposed for wideband circularly polarized application. By introducing a CT-AMC reflector, a bidirectional radiation of OSA antenna is changed to unidirectional radiation, and the axial ratio bandwidth and gain increased obviously. Moreover, electromagnetic simulations...
This study aims to quantify litchi leaf phosphorus concentration (LPC) from canopy spectra at five different growth stages. The band iteration was used to optimize the ratio vegetation index (RVI) and ratio of band difference index (RBDI). The correlation analysis, linear regression and cross validation were used to analyze the relationship between spectral data and LPC and construct the robust estimation...
Land use is critical for researches about carbon accounting, environmental protection, global climate change and sustainable development, etc. Recently, land use data production could not meet researches of land use and its change in administrative regions of province-level well under the rapid economic and natural disaster growth. This paper takes Guangdong province as an example, the land use classifications...
Since it was first proposed, the new method of power demand forecasting using a stochastic model has been greatly talked about in the scientific community and increasing number of practical applications are being developed, since it is a simple and effective approach to forecast power demand within a small time interval. However, the relevant literature still assumes that all statistic parameters...
Machine-to-machine (M2M) is a new type of communication which can be used in e-health, smart meters and so on. However a huge number of M2M devices will cause access congestion in third generation long-term evolution systems. It will bring access delays which cannot satisfy the requirements for the M2M deceives, especially for the devices with low tolerant delays. In this study, the authors investigate...
Failures are not uncommon in production data center networks (DCNs) nowadays, and it takes long time for the network to recover from a failure and find new forwarding paths, significantly impacting real time and interactive applications at the upper layer. The slow failure recovery is due to two primary reasons. First, there lacks immediate backup paths for downward links in DCN with multi-rooted...
Accurate and reliable information on land use is a basis of agricultural disaster warning and emergency action. The natural disasters typhoon, cold disaster, drought, and so on, have great influences on agricultural production in Guangdong Province, China. Through literature analysis at home and abroad, it was pointed out that Chinese HJ satellites have become important sources of remote sensing images...
This paper presents a new vertical axis propeller, which combines the turbine with the rudder and can generate thrust in all directions. It describes the modelling of the vertical axis propeller and presents the results of simulations under various conditions. The two-dimensional (2D) simulations investigate the influence of parameters such as advance coefficient, blade number and spacing distance...
Tidal current power generation system extracts energy by transferring the kinetic energy of tidal movement to the motion of power turbines. The long coastline of China contains abundant tidal energy, but not all coastal area worth exploiting. It is generally considered that a mean spring peak tidal current of at least 2 m/s is required for tidal current power exploitation. Thus we choose to evaluate...
In the data flow models of today's data center applications such as MapReduce, Spark and Dryad, multiple flows can comprise a coflow group semantically. Only completing all flows in a coflow is meaningful to an application. To optimize application performance, routing and scheduling must be jointly considered at the level of a coflow rather than individual flows. However, prior solutions have significant...
