Facial Expression Cloning with Fuzzy Membership Functions
… faces. The system described in this thesis uses fuzzy membership functions and subtractive clustering to represent faces and expressions in an intermediate space. This intermediate space allows expressions for face models with different resolutions to be compared. The algorithm is trained for …

Priority-Based Resource Allocation Model for Vehicular Fog Computing
… Dynamic thresholds are determined using the fuzzy membership functions for each vehicular attribute. Prioritization is arranged using a priority queue to identify and assign managed resources under requests and availability. Our proposed method enables fulfilling QoS standards by reducing the …

Developing and evaluating a method to disaggregate legacy SSURGO soil maps
… Next, soils are assigned preferentially using fuzzy membership functions to the slope and curvature values for each map unit until all the possible soils are disaggregated. The area percentage of each new soil is calculated, and the model is adjusted until the SSURGO-stipulated percentage of …

Determining fuzzy link quality membership functions in wireless sensor networks
… but most of these use only one link property. Fuzzy logic based link quality estimators have been recently proposed which consider a number of link quality metrics. The fuzzification of crisp values to fuzzy values is done through membership functions. The shape of the fuzzy link quality …

Fuzzy Evolutionary Approaches for Bus and Rail Driver Scheduling
… to calibrate the weight distribution among fuzzy membership functions. A Simulated Evolution algorithm then mimics generations of evolution on the single schedule produced by the Genetic Algorithm. In each generation an unfit portion of the working schedule is removed. The broken schedule is …

On-line fault diagnosis of industrial processes based on artificial intelligence techniques
… inherent ambiguity of qualitative reasoning, a fuzzy qualitative simulation algorithm, which allows a semiquantitative extension to qualitative simulation, has been investigated. The adoption of fuzzy sets allows a more detailed description of physical variables, through an arbitrary, but …
