K-means is a numerical, unsupervised, non-deterministic, simple iterative cluster method. k-means algorithm computes the distances between data point and all centers in iterative process, this is computationally very expensive especially for huge datasets. we propose an improved k-means algorithm to preprocess an efficient way for assigning data points to clusters. The improved method avoids large number of iterations, and saves running time. Experimental results show that the improved method can effectively improve the speed of clustering and accuracy, reducing the computational complexity of the k-means.

Outlier detection is a very important type of data mining, which is extensively used in application areas. The traditional cell-based outlier detection algorithm not only takes a large amount of time in processing massive data, but also uses lots of machine resources, which results in the imbalance of the machine load. This paper presents an distancebased outlier detection algorithm. These experiments show that this improved algorithm is able to effectively improve the efficiency of the outlier detection as well as the accuracy.

This paper presents an implementation of Universal Asynchronous Receiver-Transmitter (UART) controller based on Microprogrammed Controller on Field Programmable Gate Array (FPGA. Our design of UART is fully functional and synthesizable. It is coded using Verilog based top-down hierarchical design methodology and realized in Spartan-3E FPGA using Xilinx ISE Webpack 14.7. The implementation results demonstrate that the design can operate at a maximum clock frequency of 218.248 MHz. The maximum clock frequency of hardwired implementation of UART controller is 192 . 773 MHz. We also compare our Microprogrammed implementation of UART controller to the standard ROM method; our implementation uses less number of bits and hence small number of storage elements.

By the complete discrimination system for polynomial method, we obtained the classification of single traveling wave solutions to modified YTSF equation.

According to the core, drilling, logging, seismic and combined with the production test and other data, application of high resolution sequence stratigraphy theory, the Daqing oilfield in the ancient 1 block of the oilfield H2 oil layer group is divided into 1 Mid cycle, 10 short-term cycles, 1 blocks of the Daqing oil field, the formation of single sand body level high resolution sequence stratigraphic framework, for the study of the small layer, the connectivity of sand and sand body, as well as the study of sedimentary microfacies provides a very important significance for oil and gas exploration and development.

This article reviews and establishes the current state of research and technology for low-cost, portable and easy to use Brain Computer Interface (BCI) suitable for non-medical applications such as communication, environmental control, entertainment and gaming. The scope of this research is to analyse all possible technologies that are currently available to enable channel of communication between humans and electronic devices using only cerebral activities. In addition, the EMOTIV Epoc wireless EEG hardware has been reviewed

Fault deformation mechanism and internal structure of fault zone are the basis of fault sealing and fluid migration along the fault zone. The inner structure and the controlling effect of the internal structure and the control of the oil and gas are studied. Pure sandstone in the formation of the non-consolidation, semi-solid rock, the deformation mechanism of the particle boundary sliding, resulting in the particle rotation and rolling, that is, particle flow. During the consolidation stage (porosity is more than 15%), the deformation mechanism is fractured, and the fault rock is the fractured rock, and the microstructure of the formation is fractured zone. During the consolidation stage (less than 15%), the deformation mechanism is mainly characterized by rupture, the fault core is the fault zone, and the associated micro structure type is fracture. The displacement pressure of fault rocks is related to the depth of the fault, the mud content of the fault rocks and the extent of the fault rocks. At last, the paper puts forward the model of controlling hydrocarbon in the fractured zone of sand and mud interbed formation.

In this paper, we consider a novel non-monotone self-adaptive trust region method for solving unconstrained optimization problem. Unlike the usual trust region methods, our proposed the new algorithm does not only uses current iterative but also the previous information to update the trust region radius at each iteration. The global convergence of the algorithm is established under some reasonable assumptions.

HIL (Hardware in the loop) simulation test bench was developed based on the CarSim and LabVIEW software. First of all, CarSim, Real-time vehicle dynamics software, was used to build parameterized model for vehicle. Secondly, HIL simulation system, including vehicle steering wheel Angle, accelerator, brake, gear physical signals, was established based on the LabVIEW RT which was the real-time simulation environment of LabVIEW. And the steering wheel Angle sensor signal, throttle brake pedal sensor signal, gear sensor signal was introduced into the vehicle dynamics model through the hardware interface. Finally, the lemniscate road simulation test was used to verify the validity of the HIL simulation test platform. Lemniscate road simulation test included driver model simulation test and driver's practical operation HIL simulation test.
