We propose and investigate a new scheme to realize optical logic gates using polarization addition with direct detection. Two polarizations of an optical signal are modulated, respectively, by independent binary inputs to represent four different states, while direct detection is used to map the four states to the corresponding binary output. Up to 25 logic gates, including all the basic logic gates,...
This paper is related with the research and application on automation control systems in water diversion conveyance line project. Because the uniqueness and importance of the project, the process of the system design, implementation and testing was of paramount importance. This issue was approached from the plant-wide control perspective. The main tool used was a concept of the conveyance line operating...
The paper is concerned with implementation of control and management systems for water diversion infrastructure project. The Yellow River Diversion Project (YRDP) is a large scale inter-basin water diversion undertaking with the target capability of transferring 1,200 million m3 of water annually. The hydraulic structures and equipment were designed and selected with a view that a responsive control...
The paper describes the research the application of artificial intelligence technology in analyzing engineering quality and proposed a method which bases on the faulty tree analysis of the fuzzy logical system. In practice, the indeterminacy exists in the occurrence probability of basic event. Based on the previous research, this paper adopts the way of expressing the occurrence probability of basic...
This paper presents the probabilistic logic model to compute the probability distribution of the nano gate states. The characterization is based on the Markov random field and statistic physics. The primary logic gates are probabilistically characterized. The effectiveness of the method is demonstrated by a full adder and an 8-bit adder. The analysis shows that the device probability distribution...
Device failure is an important consideration in nano-scale design. This paper presents a probabilistic logic model to compute the probability distribution of the nano gate states. The characterization is based on Markov random field and statistical physics. The basic logic gates are probabilistically characterized. The effectiveness of the method is demonstrated by an inverter and the inverter cascade...
The logics with probabilistic characterized is suitable for expressing the states of nanoscale device. This paper describes the logics and the using in computing the probability distribution of the nano gate states. It is based on the Markov random field with new features, such as clique potential, initial nodes probability density. We demonstrate the effectiveness of the method by preliminary gates...
