Research on Reliability Optimization Design of Mechanical Structure Based on Computational Intelligence

In order to extend the actual service life of mechanical equipment components and realize the reasonable protection of applied structural components, the reliability optimization design of mechanical structure based on computational intelligence is studied. With the help of wavelet neural network, the established reliability and reliability index are obtained, and then the basic theory of reliability and computational intelligence technology are studied through the reliability optimization of mechanical zero structure. On this basis, the application concepts of reliability design method are defined, and the final calculation result of reliability optimization value is obtained by combining fuzzy set and level cut set, so as to realize the reliability optimization design of mechanical structure based on computational intelligence. The experimental results show that, compared with the traditional design method, the optimization design method supported by computational intelligence technology can better improve the disadvantages of mechanical structure object, and has strong practical application value in extending the reliability application time.

Mobile Augmented Reality for Campus Visualization Using Markerless Tracking in an Indonesian Private University

<p>Marker in augmented reality plays a major part to initiate a virtual object in an augmented environment. Choosing a correct and reliable marker would increase the chance of creating a more stable augmented object especially for visualizing a building structure. Unfortunately, most research on visualizing building structure uses a marker-based tracking approach where users must always bring a pre-printed paper as a tracking media. This creates a problem for every time users demonstrate a specific augmented structure object, they still need to bring a printed marker to show the augmented object. The purpose of this research is to investigate the applicability of markerless-based tracking as a solution whether it can substitute the marker-based tracking on augmented reality problems. Simultaneous Localization and Mapping (SLAM) is used as a markerless tracking method where it tracked and mapped the surface environment using feature extraction, then set an anchor at the specified location where the augmented object visualization appears. The results of the research found that from a total of 30 object detection tests, 21 objects are successfully detected and 9 undetected objects, this shows that markerless-based tracking is applicable and can substitute marker-based tracking for a structural campus visualization.</p>

Duplicated Code Slicing Technique for System Optimization

These days, the systems have been bigger upon integrations with multiple functions of hardware and software. To optimize these bigger systems, slicing technique is required to extract the duplicated codes. In this study, system dependent graph was used for slicing of duplicated codes. System dependent graph is generated upon analysis of extracted control relationship from system codes and data dependence. Duplicated control and data relations are extracted upon analysis of generated system dependent graph. Using control and data relations, which is a suggestive slicing technique, duplicated codes can be generated. Slicing technique using system dependent graph can be applied to the extraction of duplicated cross cutting modules in all programming methods regardless of the environment of structure/object-oriented program. By the suggestive method, code blocks duplicated. In the system can be sliced and system code optimization can be contributed by eliminating unnecessary codes from slicing

Haplic Chernozem Properties as Affected by Different Tillage Systems

During 2007–2011 we assessed content and quality of humic substances with relationship to soil structure. Object of study was Haplic Chernozem (Hrušovany nad Jevišovkou, Czech Republic) under three different tillage systems: – conventional ploughing to a depth of 0.22 m (CP); – reduced tillage with shallow harrowing to a depth of 0.15 m (RTSH); – reduced tillage with subsoiling to a depth of 0.35–0.40 m (RTS). Isolation of humic acids was made according to IHSS standard method using spectrometer Shimadzu 8700. Aggregates stability was determined by wet sieving method. Results showed that macrostructure stability was directly connected with time of sampling and content and quality of humic substances. After five years of experiment statistically significant differences in humic substances content were found. The highest structure stability, quantity and quality of humic substances were achieved under reduced tillage with shallow harrowing.

Research on P System with Chain Structure and Application and Simulation in Arithmetic Operation

Considering the advantages of distribution and maximum parallelism of membrane computing and availability of discrete Morse theory to deal with discrete structure, in this paper, combining discrete Morse theory and membrane computing, a novel membrane structure—P system with chain structure, is proposed, which is constructed on the basis of discrete gradient vector path of the discrete Morse theory. At the theoretical level, due to its unique chain structure, compared with traditional P system, its structure, object, and rule are described in details. In the practical aspect, a specific application example, P chain system for arithmetic operation, is presented to demonstrate the superiority, computational efficiency, and ability of P system with chain structure. Moreover, a simulation system of arithmetic operations based on P chain system is designed, giving a visual display of the implementation of P chain system for arithmetic operation, and verifying the feasibility and effectiveness of P chain system.

A Study of RCS Parallel Computing Based on MPI and FDTD

FDTD(Finite Difference Time Domain) method is widely applied to many branch of computational electromagnetics because of its simple principle and programming. In general, 10 gridding must be used in a wavelength, and time pedometer is restricted because of the request of numerical dispersive and Courant stability condition. Thus, a large number of memory and computational time will be consumed when big dimension and complex structure object is considered, which is beyond the capability of single computer. FDTD Parallel computing technology is a available choice. We researched the computation of RCS based on FDTD and MPI, and the program was done, and its correctness was tested by comparing different result.
