Abstract: In this note, we continue the works in the paper [Some properties of L-fuzzy approximation spaces on bounded integral residuated lattices", Information Sciences, 278, 110-126, 2014]. For a complete involutive residuated lattice, we show that the L-fuzzy topologies generated by a reflexive and transitive L-relation satisfy (TC) L or (TC) R axioms and the L-relations induced by two L-fuzzy topologies, which are generated by a reflexive and transitive L-relation, are all the original L-relation; and give out some conditions such that the L-fuzzy topologies generated by two L-relations, which are induced by an L-fuzzy topology, are all the original L-fuzzy topology.

Abstract: This paper presents a method based on neural network (NN) for estimating the properties of semiconductor thin film. Through the effective learning process, NN is able to catch the relationship between input and output pairs bypassing the complicated statistical steps such as model hypothesis, identification, estimation of model parameters, and verification. Such an estimator then can be developed to be a smart mechanism which can help the technician to set the relevant control parameters in the manufacturing process of thin film. In this research, the thickness and refractive index (RI) of thin film were estimated by the well learned NN model. From the studied results shown, the properties of thin film indeed could be estimated in advance according to the relevant control parameters in the manufacturing process. That also means the estimator we developed could be built and fulfilled its function.

Abstract: This paper presents a sectored antenna array indoor positioning system (IPS) with neural network (NN) technique. The hexagonal positioning station is composed of six printed-circuit board Yagi-Uda antennas and Zigbee modules. The values of received signal strength (RSS) sensed by wireless sensors were used to be the information for object’s position estimation. Two NN models, including NN with back-propagation (BP) learning algorithm and probabilistic NN (PNN), were applied to perform the positioning work for a comparison. In the experiments, an 8x8 square meters indoor scene was performed and 288 points and 440 points were experimented in this area. The positioning results show that both NN models have the average error less than 0.7 meter. In other words, the proposed positioning system not only has the high positioning accuracy, but also has the potential in real application.

Abstract: Growing Development of new metric technology, communications on one side, and variety in IT and incremental information on the other side in designing and manufacturing automation station systems make the pioneers of this industry change the system with the aim of creating "a world, a technology, a standard" in this industry. This evolution led to create a new technique for designing automation systems which is called IEC 61850 standard. Considering the agreement on developing and using this standard, applying this in station automation systems was taken into account since 2005. The new technology needs new interfaces to connect the high voltage switchgears such as modern current and voltage measurement transformers to station automation control systems. By introducing the new technology and using IEC 61850 protocols, designing automation systems with decentralized structure is possible and has a lot of advantages, however great care is needed in designing such system so that system reliability will not be impaired. In this thesis, for better understanding, we first explain briefly the old station structures and their transition and then the IEC 61850 standard structure will be investigated and this investigation includes the way of data transfer. Finally we refer to the effect of this standard on the structure of high voltage station automation system. In power distribution systems, IP and IEC-61850 are introduced as a security ring with more importance of communication, that in the meantime, IEC-61850 as the new international standard electrical station, is capable of providing the Integration, protection, control, measurement and monitoring functions within the stations with high-speed. So not only can prove the importance and the need to replace the IEC-61850 standard as the protocol with high speed data transfer capability ,but also we will also see reducing the time and power transmission losses in the automation network

Abstract: It’s always difficult to satisfy both strict requirements of dynamic performance and settling performance of high-precision and high-acceleration point-to-point motions on electronic packaging equipment, i.e., Die bonders, Wire bonders, Flip-chip bonders, Wafer bumping machines, and so on. Focusing on this difficulty, Fuzzy logic is promoted in this paper to fine tune feed forward coefficient parameters of motion systems on packaging equipment to satisfy multiple targets of dynamic and settling performance requirements. This intelligent fine tuning approach, with achievable multiple motion targets, provides a therapy to automate and optimize motion system performance on packaging equipment, help on development and mass production of semiconductor packaging equipment, and improve machine intelligence.

Abstract: In the era of e-commerce, the logistic distribution center is put in the center role of order picking for the sake of meeting the needs of different customer orders, hence, improving the automation and work capacity of distribution center becomes research priority in the fields of logistics and warehousing. The objective of this article is to solve the shortcomings of currently traditional distribution center picking system with high automation by introducing a new method of picking provided by Amazon’s Kiva system, that is, mobile racking with goods is broke out to sorting table by Kiva mobile robots named AGVs (automated guided vehicles), which could not only reduce the walk time and labor cost, but improve efficiency. This article starts with the constitutive requirements of the Amazon KIVA robotic systems, and then some key problems of Kiva picking system and design optimization about task allocation and path planning of multi-robots are demonstrated respectively in this article. Finally, the content is summarized and the application of robotic system in is simply demonstrated and prospected.
