Polarimetric SAR interferometry (PolInSAR) is a promising remote sensing technique that has been frequently used for extracting forest height. The existing methods such as the ESPRIT method and three-stage inversion algorithm tend to underestimate the forest height due to attenuation of the electromagnetic waves in the ground medium. This paper proposes an improved hybrid inversion method based on...
The applications of linear programming with fuzzy constraint coefficients are numerous and various over the past years. This paper proposes a new approach, a modified two-stage differential evolution (DE) algorithm, to solve linear programming with fuzzy constraint coefficients approximately. In the first stage of the proposed DE, the generation of fuzzy numbers for each imprecise coefficient is simulated...
In complex networks, communities often show the presence of homophily between members, since homophily is the tendency of individuals to associate and bound with similar others to form densely interconnected groups. In this paper, we propose a new bidirectional label propagation community detection algorithm, called Dis-Sim, based on the fundamental idea that a node and its most similar neighbors...
This study investigated an optimization technique for improving the inter-band reflectance relationship known as the vegetation isoline equations. A single factor was introduced into the recently developed vegetation isolines [Miura et al. 2015] to decompose the higher-order interaction terms of photons between the canopy layers and soil surfaces. A set of numerical experiments based on the canopy...
Task allocation is an essential part of many applications of WSANs. The key problem of task allocation in these systems such as intelligent minefield is how to obtain the node-target assignment. Mathematical model with task effectiveness as the evaluation index was built on the analysis of multi-node cooperative decision problem. Combing with the target's parameters and node's own status, the influence...
An adaptive region-of-interest panoramic system is firstly proposed to achieve high-quality and real-time processing for 360-degree panorama. This technique prevents from processing a whole 360-degree image by only focusing on the particular area. Several memory optimizing methods, including cache-miss rate and memory buffer size reduction, are also applied with the purpose of improving the run time...
From simulation experiments of the multi-objective optimization control of wastewater treatment process (WWTP), it can be found that the number of obtained Pareto solutions is less using the normal non-dominated sorting genetic algorithm-II (NSGA-II) sometimes. To achieve a satisfactory optimal performance, an improved NSGA-II algorithm based on differential evolution mechanism is proposed in this...
This paper deals with the optimal fault-tolerant operation of a 5-phase permanent magnet (PM) brushless DC (BLDC) drive. In particular, the companion paper (Part I) proposes the optimization of the current supply to obtain the maximum power in healthy conditions and its analytical solution. In the present paper (Part II), by constraining the proposed model with healthy and fault specific conditions,...
We propose a dynamic portfolio rebalancing approach within the mean-risk framework, in which the riskaversion coefficient is adjusted according to market trend information captured by a technical indicator. We employ Gini's Mean Difference as the risk measure and the moving average as the technical indicator. We conduct a thorough empirical evaluation with a rolling horizon approach using the S&P...
This paper proposes a new approach for constrained multiple model (MM) maximum a posteriori (MAP) estimation through the expectation-maximization (EM) method by using our previously developed constrained sequential list Viterbi algorithm (CSLVA). The approach is general and applicable for any type of constraints provided they are verifiable. Specific algorithms for implementation are designed, and...
The edge coloring problem of graphs has interesting real life applications in the optimization and the network design, such as the file transfers in computer networks. A $k$-edge coloring of a graph is a mapping $\phi: E(G) \rightarrow \{1,\cdots,k\}$. Let $f(v)$ denote the sum of the colors on all the edges incident to $v$. A $k$-neighbor sum distinguishing edge coloring of is a $k$-edge coloring...

In the companion paper (Part II) the drive is considered both in healthy and faulty...
In this paper, we propose a robust genetic programming model for a dynamic strategy of stock portfolio insurance. With portfolio insurance strategy, we need to allocate part of the money in risky asset and the other part in risk-free asset. Our applied strategy is based on constant proportion portfolio insurance (CPPI) strategy. For determining the amount for investing in risky assets, the critical...
In this paper, we study the missing sample recovery problem using methods based on sparse approximation. In this regard, we investigate the algorithms used for solving the inverse problem associated with the restoration of missed samples of image signal. This problem is also known as inpainting in the context of image processing and for this purpose, we suggest an iterative sparse recovery algorithm...
Dense views are needed urgently for autostereoscopic three-dimensional (3D) displays. A dense view synthetization system with three input views which are captured by a three-camera rig is presented. In the system, an image preprocessing step is presented before rendering dense views, in which both color and depth images are optimized by the proposed adaptive joint view optimization algorithm. Then...
