    A fuzzy method for a particular kind of pixel classification is proposed. It is one of the most important results in the development of an inspection system for a silk-screen printing process. The classification algorithm is applied to a reference image in the initial step of the printing process in order to obtain the regions which are to be checked by applying different criteria.

    In engineering applications of fuzzy logic, the main goal is not to simulate the way the experts really think, but to come up with a good engineering solution that would (ideally) be better than the expert's control. In such applications, it makes perfect sense to restrict ourselves to simplified approximate expressions for membership functions. If we need to perform arithmetic operations with the...

    A new fuzzy logic controller, which is suitable for a system with analog input and output, has been implemented in a monolithic form. It employs an architecture where time sweeping of variables allows continuous evaluation of fuzzy inferences and defuzzification without having to discretize input and output variables using A/D and D/A converters. Direct processing of the analog input signal is use... View full abstract»

    The development of a systematic procedure for the design of fuzzy logic controllers (FLCs) has been of interest since their introduction. As the dimension of the system's input/output space increases, the design problem becomes exponentially more difficult. By partitioning the input space into smaller, more manageable pieces, it is possible to simplify the design procedure. The problem then become... View full abstract»

    Feedback fuzzy systems take their own output as input and define nonlinear rulebased dynamical systems. They use a fixed number of rules to model other dynamical systems while feedforward fuzzy systems suffer from exponential rule explosion. But most feedback fuzzy systems are not themselves stable. Generalized additive fuzzy systems are a special class of feedback fuzzy systems that compute a sys... View full abstract»

    Radiotherapy is an effective treatment for many cancer patients. The volume to be irradiated, i.e. the target volume, is determined by the radiotherapist who aims, in this process, at including the whole tumor at the same time as saving the surrounding healthy tissues as much as possible. The target volume definition is a difficult step, since the imaging techniques on which this process is based ... View full abstract»

    The establishment of fuzzy control rules has long been an important issue in fuzzy controller design. Several ways have been developed to construct fuzzy control rules, which may be based on the operator's control action, expert's experience and control engineering knowledge. However, trial-and-error efforts are inevitable in most methods and, consequently, make the design procedure a time-consumi... View full abstract»

    Traffic control involves analysis of both detected traffic flow and environmental conditions. Due to individual behavior of traffic participants, and the inherent uncertainty of weather condition interpretations, a mathematical model can not fully describe traffic control problems. The paper discourses two aspects of a traffic management system for multi-lane highways with variable road signs. Fir... View full abstract»
