Abstract: We have proposed a building automation system to control the active systems such as lightning including artificial lighting on/off, air conditioners and safety features like earthquake alarm, fire alarm and gas alarm to make the building services more advanced.

Abstract: When the micro lens array machined by an ultra-precision machine was used in 3D computer graphics, a novel format of depth map image was invented with adaptively variable data length for multi requirements of different 3D computer graphics applications. A depth map is an image or image channel that contains information relating to the distance of the surfaces of objects a scene from a viewpoint. Depth maps can be applied for many functions: defocusing, rendering of 3D scenes, shadow mapping and other distance information-related applications.

Abstract: As the Required Data Rate for VLSI System Communication Increases, Channel Bandwidthlimitation Becomes a Crucial Problem as High-Frequency Channel Loss Degrades the Transmission Performance.In this Paper, we Compare Non-Return-to-Zero (NRZ) Binary and 4-PAM (pulse Amplitudemodulation) Coding Techniques for High-Speed Data Transmission by Fabricating a Test Board of a Microstripline. by Extracting the Micro-Strip Line Parameters, we Carry out Co-Simulations to Evaluate Spectrallyefficient Coding for High-Speed Data Transmission.We Consider the Conditions for which 4-Pamsignaling Provides an Advantage over NRZ Signaling from the Viewpoint of Channel Profiles.

Abstract: A quantum computer is the computer technology and the micro physical scientists will combine the technology achievements. Quantum computer is the processing of information by using the quantum properties of particle, a new concept quantum laws to control information transmission and processing of computer. Light has the advantages in space time parallel and high-frequency radiation, which makes the optical become the main target of research model the future of computers. This did not prevent the three valued logic calculus is still an important part of the three values of optical computer. It is precisely because the three value of optical code decoder and the three value, importance, ALU logic optical so, in three valued optical computer all the key parts, we firstly research the value of three logic optical light coding, decoder and a value of three.

Abstract: Vehicle Routing Problem (VRP) is one of the core issue of logistics distribution, for traditional precision algorithms and heuristic algorithms had low accuracies or easily fell into local optimal solutions, it was difficult to obtain the optimal solution. This paper proposes a heuristic artificial fish school algorithm (HAFSA) for VRP, firstly, three-dimensional particle coding method is applied to vehicle routing code, and infeasible and inadequate artificial fish coding for heuristic repair, secondly HAFSA steps are given, finally the algorithm is tested through a simulative example. The experimental results show that compared with traditional genetic algorithm (GA) and particle swarm optimization (PSO), AFSA and their extension algorithms, HAFSA has a better performance in time and space cost and convergence.

Abstract: Given contribution deals with a group technology and methods of classification of the components. Author proposed a component base for CNC processing centre EMCO Concept MILL 105, which is a part of manufacturing system iCIM 3000 by FESTO. Designed manufacturability components are coded and classified based on shape similarity.

Abstract: In this paper we describe the practical application of RFID in production and logistics at the Norwegian board and packaging manufacturer Glomma Papp. Delivery of the system took place during late 2013 and 2014. The company’s goal was to automate its production flow and logistics. There were two options: bar codes or RFID.

Abstract: To solve the problem of design and manufacturing on the production of many varieties of small batch, the parts grouping method that based on clustering algorithm, clustering validity index and BP neural network method for new parts is proposed. At first, mathematical model of part clustering is built, and parts grouping is based on the similarity of data and cluster centers which is calculated by Euclidean distance, then the effectiveness of parts group is tested by Function Index and optimal number of clusters group can be found. The algorithm is achieved by Matlab clustering toolbox, so the best part family structure is built. Furthermore, the grouped parts are used to train the BP neural network toolbox in Matlab, then simulate new parts on network to find the match group. At last, a case study was also presented to verify the feasibility of this method．

Abstract: The wavelet analysis has some important applications in image processing, including image compression, image de-noising and so on.Wavelet analysis for two-dimensional image compression is a key aspect in the field of its applications.This paper studied the application of wavelet analysis in BMP image coding, the characteristics of wavelet coefficients and wavelet subimage, these lay the foundation for further selection of wavelet coefficients and optimize, and analyzed the theory of EZW algorithm, illustrates the better results of the applications on using wavelet theory in image processing.

Abstract: In order to improve the utilization of system resources and enhance the network throughput, this paper focuses on the cooperative network coding which combines the advantages of both network coding and cooperative diversity. Both theory and simulation proves that it can provide better performance in BER and NC gain.
