This paper extends the idea of switching T-S fuzzy systems with linear consequent parts to nonlinear ones. Each nonlinear subsystem is exactly represented by a T-S fuzzy system with Lure’ type consequent parts, which allows to model and control wider classes of switching systems and also reduce the computation burden of control synthesis. With the use of a switching fuzzy Lyapunov function, the...

In laser manufacturing, the cutting parameters, such as power, speed, assist gas pressure, and stand off distance, have a great influence on quality of machined parts. To ensure part, process information (cutting parameters) needs to be manually assigned adjusted according different geometry characters part edges, like arc line segment. The contours are then used for generating paths, leaving b...

In the computer aided medical image process, image segmentation is always required as a preprocess stage. Fuzzy c-means (FCM) clustering algorithm has been commonly used in many medical image segmentations, particularly in the analysis of magnetic resonance (MR) brain image. However, all of these FCM methods are computation consuming that is difficult to be used in real time application. In the...

In humanitarian relief operations (HRO), due to the excessive number of relief organizations, multiple organizational coordination is a demanding and complicated task. Considering such a problem, this paper proposes a two-phase mechanism to coordinate multiple heterogeneous relief organizations in a decentralized HRO logistics network. To address such a problem, first a bi-level mixed integer l...

Exploring temporal coherence among light transport paths is very important to remove temporally perception-sensitive artifacts in animation rendering. Using the contribution of a light transport path to all frames in an animation as the sampling distribution function allows us to adapt Markov Chain Monte Carlo (MCMC) algorithms to exploit the temporal and spatial coherence among paths in order ...

task assignment problem (tap) involves assigning a number of tasks to a number of processors in distributed computing systems and its objective is to minimize the sum of the total execution and communication costs, subject to all of the resource constraints. tap is a combinatorial optimization problem and np-complete. this paper proposes a hybrid meta-heuristic algorithm for solving tap in a h...

trajectories generally used to describe the space and time required to perform a desired motion task for a mobile robot or manipulator system. in this paper, we considered a cubic polynomial trajectory for the problem of moving a mobile robot from its initial position to a goal position in over a continuous set of time. along the path, the robot requires to observe a certain acceleration profil...

This paper studies the problem of distributed computation over a wireless network of resource constrained nodes. This problem applies to many emerging wireless sensor networks, including those used for body sensing, structural health monitoring, and various cyber-physical systems. Computational tasks in these networks typically require far more sophisticated data processing beyond commonly-stud...

For the design of safety-critical embedded systems, many different aspects have to be considered to guarantee the correctness of the system. Besides functional correctness, these systems also have to meet real-time constraints expressed in terms of end-to-end deadlines. End-to-end deadlines claim that certain system events must occur within a given time interval. This means that all involved co...
