This paper presents a new method to calculate control delay at signalized intersection or other types using speed-time data. For the control delay which composed of deceleration delay, stopped delay, and acceleration delay, it is important to determine the critical points of each delay. This paper uses speed as well as acceleration to determine the critical points and get an accurate result. Different with other researches, it uses the area that composed of real time speed curve and desired speed curve, divided by the downstream speed, to get the control delay precisely. This method needs less data than other methods and can be applied to any traffic condition including variant desired speed or volume. This paper also provides a rapid method, which doesn’t need to determine the critical points, to estimate control delay, and the precision is acceptable.

Manufacturing system is becoming larger and more complicated. Global manufacturing chains have become common in the new millennium. Internet and intranet integrate the advanced manufacturing system. To perform remote monitoring and diagnosis in such chains and systems, real-time data compression has become a core factor in the efficient and effective exchange of information exchange via computer networks. This paper presents a new technique for compressing data using a kernel-based method. Overcoming the drawbacks of support vector techniques — that is, fast decompression but slow compression — the new method exhibits high speed in both phases. In addition, the new method can also be applied for pattern classification. Based on strain signal example tests derived from sheet metal stamping operations, the new method is very effective. The proposed technology has enormous potential in the application of advanced manufacturing system monitoring and control through internet or intranet.

This paper introduces a new method for production development with the usage of process observation, fuzzy logic, and sensoring. In collaboration with experts in the field of food science, design, a program was developed that can simulate the behaviour of a semifinished product during preparation. A factory producing bakery products applied sensors in order to gain real-time data that can be integrated into the program. Because of all the uncertainty of a preparation process, the optimal baking temperature and time are different in each package of the product. With the previously mentioned program, it is possible to provide the optimal values for each package.

To meet requirements of time data dynamic growth , and reflect the different effect to the different segment of time series over time, a new method of piecewise linear representation, called tangent piecewise aggregate approximation (TPAA) is proposed based on hyperbolic tangent function. The method can not only meet requirements of time data dynamic growth, but also reflect time property of the time series. Compared with the existing methods, TPAA method can effectively query time series online.
