Heating, Ventilation and Air Conditioning(HVAC) systems perform environmental regulations to provide thermal comfort and acceptable indoor air quality. Recently optimization based Model Predictive Control (MPC) has shown promising results to improve energy efficiency of HVAC system in smart buildings. However rigorous studies on incorporating data driving comfort requirement into the MPC framework...
In this paper, we propose a Takagi-Sugeno-Kang (TSK) fuzzy model for a four-Mecanum-wheel omni-directional mobile free-base (4MW-ODMFB) with system uncertainties and external disturbances based on the model given in [12], [13], and then design an adaptive sliding-mode control (ASMC) system for trajectory tracking of 4MW-ODMFB, which combines the techniques of adaptive control and sliding-mode control...
Aiming at the DC power supply instability in micro-grid, a Flywheel Energy Storage System (FESS) based on magnetic integrated structure bidirectional DC/DC converter is proposed. In this system, for the convertor, three magnetic elements (isolation transformer, resonant inductor and transformer) are integrated into a single core via magnetic integrated technology. The FESS can not only supply the...
Reliability prediction profile is the diagrams of environmental parameters and time. It is used for simulation. It is in accordance with certain rules to deal with environmental reliability test profile. And it must reflect the actual stress situations. This paper studies temperature and vibration parameters of the profile, and determines its effect on the failure life of product. For the reliability...
Deformation is an important research problem in computer graphics. In the paper, a new concept of flexible coordinate space is proposed to successive deformation process between any two mutually elastically deformable planar polygons. Then a new morphing technique based on elastic coordinate space is proposed. By linear interpolation of "coordinate basis points", then we can reverse out...
Today's interdomain routing is traffic agnostic when determining the single, best forwarding path. Naturally, as it does not adapt to congestion, the path chosen is not always optimal. In this paper, we focus on designing a multi-path interdomain forwarding (MIFO) mechanism, where AS border routers adaptively forward outbound traffic from a congested default path to an alternative path, without touching...
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 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...
Nitrogen fixation by nitrogenase is energetically costly; therefore, the regulation of nitrogenase activity is essential for the growth of the diazotrophic Alphaproteobacterium Azospirillum brasilense. Nitrogenase activity is regulated at transcriptional and posttranslational levels responding to the concentration of available ammonium in the environment. At nitrogen‐limiting condition, dinitrogenase...
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...
