The intima media thickness (IMT) of the common carotid artery (CCA) can be used to predict the risk of atherosclerosis. Many image segmentation techniques have been used for IMT measurement. However, severe noise in the ultrasound image can lead to erroneous segmentation results. To improve the robustness to noise, a fully automatic method, based on an improved Otsu’s method and an adaptive wind-driven optimization technique, is proposed for estimating the IMT (denoted as “improved Otsu-AWDO”). First, an advanced despeckling filter, i.e., “ Nagare’s filter” is used to address the speckle noise in the carotid ultrasound images. Next, an improved fuzzy contrast method (IFC) is used to enhance the region of the intima media complex (IMC) in the blurred filtered images. Then, a new method is used for automatic extraction of the region of interest (ROI). Finally, the lumen intima interface and media adventitia interface are segmented from the IMC using improved Otsu-AWDO. Then, 156 B-mode longitudinal carotid ultrasound images of six different datasets are used to evaluate the performance of the automatic measurements. The results indicate that the absolute error of proposed method is only 10.1 ± 9.6 (mean ± std in μm). Moreover, the proposed method has a correlation coefficient as high as 0.9922, and a bias as low as 0.0007. From comparison with previous methods, we can conclude that the proposed method has strong robustness and can provide accurate IMT estimations.

“…For the second case study in both cases, GA and TWDO reached the better results for both best and mean values, but TWDO present almost none variation among all the 50 runs performed showing an enhance of the accuracy of the method compared to its original algorithm. From each of the study cases, it can be noticed that the implementation of the Tsallis distribution for the control of the evolution parameters enhanced not only in terms of results but also in terms of accuracy that allowed to put a recent and promisor method, with lots of variants possibilities [40][41][42], between the ones most used techniques for heat exchangers optimization. Yet, it is important to notice that the proposed variant of the algorithm could enhance the convergence and avoid premature stagnation of the optimization process.…”

This paper presents an optimization of spiral heat exchangers by wind-driven optimization and a novel variant of this algorithm by the insertion of a statistic distribution to self-adapting of the evolution parameters of the algorithm. Spiral heat exchangers are the ideal type for cooling slurries and fluids that presents high viscosity and is very common in food and petrochemical industries. The variables used for the optimization were the spacing channels for hot and cold streams, the length, the width and the thickness of the heat exchanger. Two case studies were presented where the minimization of the cost and the maximization of the overall heat transfer coefficient were implemented. Reductions about 4.46 and 23% were obtained for the cost and increases about 18.8 and 16.4% were reached for the overall heat transfer coefficient for each case study in comparison to previous works. The proposed technique reached better results in all the simulations, in some cases with GA, but performed better accuracy among all the simulations.

“…The third type is a special kind of heuristic optimization, which is derived from physical laws and provides a more theoretical basis for the convergence of the iterative formula. One typical representative is wind driven optimization (WDO) [25,26], which describes the motion of air particle through Newton's second law of motion and ideal gas law. Because they do not rely on the mathematical properties of the objective functions, this kind of optimization algorithm is widely used in engineering applications [27,28].…”
