This paper discusses influence of sloping ground on electric field under overhead lines. Sloping ground is first transformed into flat ground by use of conformal mapping. Then the analytical expression of electric field is obtained by mirror method. The calculation method of electric field with sloping ground is verified by an example with analytical result. At last, electric field under overhead lines with varying slope angle and distance from sloping ground to overhead line is calculated to show their influences.

The power efficiency target is becomes the first goal of current hardware system. The workload under cloud computing environment needs to be accelerated by hardware as more as possible, in order to improve the overall power/performance efficiency. The traditional CPU-FPGA architecture can not handle fine granularity routine of algorithm by FPGA hardware in a effective way, as well as challenge on programming model. This paper proposed a memory/cache coherency based CPU-Cache-FPGA architecture to perform an effective transparent communication between software threads on CPU and hardware threads on FPGA. In a sorting application example, the proposed architecture can gain 2.6 times acceleration ratio than traditional CPU-FPGA architecture, as well as a simplified programming model.

This paper presents a method for using the UWB ranging & communication modules (RCM) and designing ARM9 controllers to set up Self-organized WSN indoor localization system. It is the mobile target that measure the distance at the same time, so it needn't to synchronize the clock of the base station and can obtain real-time position information. The most advantage is that the mobile tag can detect the base stations nearby automatically and along with these base stations to form a self-organized wireless sensor network. The localization system can apply in large indoor range and the positioning error is less than 0.2m.

Due to the fact that most business considered only product delivery to customer in their supply chain, follow-on logistics support often run short. It often occurs that the supply chain needs to be reconstructed or repaired when products are no longer manufactured. Military components or systems, in particular, will encounter the problem of Diminishing Manufacturing Source and Material Shortage (DMSMS) so that it needs supply chain management repair actions during its deployment phase. Due to DMSMS problems, the availability of parts is affected and the operation and support cost of electronic systems are increased. This study uses the cross-related attribute of concurrent engineering to collect and analyze maintenance data system of the customer's operational data. The concurrent engineering (CE) technique is integrated with DMSMS problems and thus results in increased efficiency of the production and the improvement of product quality. This paper discusses investigation architecture of DMSMS problem and an impact analysis of a fighter electronics system for the span of its product life cycle. It is hoped that this technique can provide a reference for management and decision making of managers when new products enter the market that they not only meet customer requirement, but also enhance company competitiveness.

In recent years, LBS (Location-Based Service)have been widely used. According tithe historical location of user, location service providers may analyze the user's interests, health and other personal privacy. The traditional k-anonymous protection method for trajectory mainly depends on the European space but not consider the road networks. In this paper, we proposed a method for trajectory privacy protection based on the segmented fake trajectory under road network. This method generated the fake position for the sampling location of real trajectory in different time, and generated the segmented fake trajectory in different time intervals. For the segmented fake trajectory which satisfied in the demand of privacy, according to the order of time, we connected them to generate the integrated fake trajectory. This method can both ensure the road network L-diversity and trajectory L-diversity. Through the experiment results, we proved that this method have a better effect for the user's real trajectory protection.

The method of orthogonal projection is introduced according to the problem of feed forward parameter optimization in linear servo system with high frequency response. At first, orthogonalized basis functions are constructed and the control system is projected onto the axes of the basis functions. Then system parameters are identified along the axes of basis functions by iterative learning and high speed response are compensated by feed forward. The method extends the iterative learning from time domain to the space of orthogonalized basis functions. The simulations and experiments show this method can significantly improve the tracking and high-response performance of linear servo system and meet the high speed and high precision requirements.

Efficient task scheduling is a challenging aspect of achieving high performance in parallel programming. Aiming at the problem that many heuristics for this NP-hard problem were always developed based on homogeneous systems and ignored the heterogeneity of processors which are not met on real parallel systems, this paper presents a heuristic algorithm based on list and task duplication for scheduling Out-Tree task graphs in heterogeneous computing systems, named HHAS_OT, which tries to assign tasks to scheduled processors to balance the loads, minimize the number of processors used and improve the schedule performance without increasing the time complexity of the algorithm. The comparative study shows that our scheduling algorithm could achieve shorter schedule length while using less number of processors.

A novel approach for OH-PLIF image processing, namely conditioned level-set (CLS) method, is presented in this paper. The complete CLS method consists of raw image pre-processing, adaptive intensity shareholding for linearization, initial contour extraction, region-lock optimization and level set iteration. The successful application of this method to typical molecule diffusion flames demonstrates its robustness to noise sensitivity and flame topology, and its outperformance over traditional edge detectors in terms of flame contour identification. The CLS method provides possibility to further image analysis such as mean reaction zone tracking. Based on the results from RANS simulation with adequate modelling, a novel numerical-aided approach for concentration calibration is also proposed. The CLS method can readily be employed to experimental images obtained from other planar scalar measurements. The proposed method has potential to be integrated to image processing modules of scientific software.

It cannot reflect the real situation for analysis of flexible coupling-rotor system if the flexible coupling is viewed as shaft or directly ignored. After carefully analyzing the responses in different speed and different unbalance displacements considering the threaded coupling, the accurate threaded coupling-rotor system is established using finite element method. Meanwhile, the threaded coupling-rotor system with rubbing failure is also analyzed in this paper. The results show that the flexible couplings has obvious effect on the vibration characteristics of the failure rotor system. The flexible coupling will play a more important role at high rotational speed.
