Consider the problem of energy loss caused by inefficient use of energy in Wireless Sensor Networks (WSN). A clustering energy-efficient transmission protocol for wireless sensor networks based on ant colony path optimization (CEETP-ACPO) is proposed. Firstly, use the distributed cluster computing energy-efficient routing scheme (DCCERS) to select cluster heads according to the center of gravity and...
A method based on variable horizon predictive control is proposed in the paper for nominal trajectory guidance. Firstly, a feasible reference trajectory is generated by the Gauss pseudospectral method. Then, curvature is employed to represent the smoothness of obtained trajectory and predictive horizon is selected according to the curvature. Different predictive control optimal problems are established...
Container, as a light-weight virtualization solution, emerges in recent years, and provides effective approaches for managing computing resources. Due to the complexity of the containerized computing environment, setting up runtime configuration presents a great challenge. To make better use of hardware resources and simplify the processes of environment setup, we propose a resource provisioning approach...
This paper describes detailed 3-D scene editing procedure, using an on-screen declarative scheme. The aim is to relieve users from low-level manipulation metaphors related to object, light or camera positioning in a 3-D environment. The solving process is formulated as an optimization problem searching the parameters (transformation matrices) that can in some way be defined as optimal, and subject...
This paper proposes an optimal power flow (OPF) algorithm based on quadratic modeling and incremental loading of the network. The proposed OPF algorithm is robust and highly efficient for large-scale power systems. Robustness is achieved by the design of the algorithm to operate on infeasible but optimal points and move towards the feasible and optimal operating point. Efficiency is achieved by (a)...
This paper indicated an inactive preference-weight method for Genetic Algorithm (GA), which can turn the individual's preference into weight preference in the multi criterion satisfactory optimization. DM can use the preference-weight to rebuild the fitness function, and according to binary relations of sample points based on the information of DM's preference, inactively modifies the evolution direction...
In the practice of evaluation of optimum FRP trawler type, DM has to face multi disciplines and lots of uncertain or fuzzy parameters. This paper proposes the use of symmetrical fuzzy collaborative optimization model, and the traditional ship type evaluation model is decomposed into three subsystems, i.e., technological, economy and decision-making computation discipline. The fuzzy cut level optimized...
This paper describes a new formulation of the security-constrained optimal power flow (SCOPF) problem and proposes a sequential linear programming algorithm for its solution. The new formulation introduces mismatch variables to ensure that the algorithm remains in the feasible region. Thus the algorithm starts from an arbitrary state: mismatch currents are computed and introduced at each bus to make...
