Using exhaustive search for a precise solution is likely not preferable, since the complexity and execution time increases as factorial of input. So people attempt to look for a method which could provide a reasonably good solution with fast response, which heuristic and metaheuristic approaches are superior. In this paper, we will discuss briefly about some common heuristic and metaheuristic ones, as well as their principles and how they are applied to seek the optimal routes in a predefined graph. Then we come to a realistic application in logistics that AGVs have to allocate the best routes and order to achieve the tasks given, by simulation in MATLAB GUI program.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121701777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chrome plating is the most widely used, especially in the dimensions restore of undersized parts. The mechanical properties of details will change when chrome plating on. There are many studies show that the chromium coating greatly affects the fatigue strength of the machine parts. In this study, the fatigue strength of the substrate (C45 steel) and chrome plated with the thicknesses of $1theta, 3theta, 6theta $, and $ 9theta $ micrometers were examined The results show that residual stress tensile and microcrack always exist in the chromium coating due to hydrogen embrittlement in the process of plating. As the coating thickness increased, the residual stress tended to decrease while the microcrack density increased Decrease in fatigue life was observed for coated specimens in comparison to base metal. Fatigue strength goes down when chromium layer thicknesses increase. $X$-ray diffraction (with Cu-Ka radiation) technique is used to determine the residual stress. Microscope optics and scanning electron microscopy (SEM) are used to evaluate the cracks of the chromium coating.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123911867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, we proposed a novel observer for estimating not only aerodynamic torque in wind energy conversion systems, but also d-axis and q-axis currents. Therefore, in the proposed control system, only the rotor speed of the generator is required to be measured. It should be noted that this is the first time, such a control system can do that for wind energy conversion systems. To form a complete control system, we use linear optimal control method for tracking the optimal trajectory of a generator. In this paper, the permanent magnet synchronous generator is used. In addition, on the basis of the Lyapunov theory and Sum-Of-Square technique, the conditions for observer synthesis are derived in the main theorem. The simulation results show that our control system with proposed robust observer can effectively track the speed reference in the conditions of unknown wind speed and stator currents.","PeriodicalId":344653,"journal":{"name":"2018 4th International Conference on Green Technology and Sustainable Development (GTSD)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131299078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To avoid the error occurred from the cell and nucleus segmentation process, we proposed the set of simplified features derived from the two-dimensional Fourier spectrum using the discrete Fourier transform. The features in the proposed method are obtained from the frequency components along the circle of radius centered at the center of the spectrum and the frequency components along the radial line having an angle. Each section of frequency components is divided into subsection. Mean value of each subsection are computed and used as the features for classification. The features are used to discriminate cells as a two-class problem to classify between the normal and abnormal cell. Classification experiments are conducted using 5-fold cross validation. The efficiency of four classifiers including K-nearest neighbor (KNN) support vector machine (SVM), Random Forest, and Adaptive Boosting (AdaBoost) are investigated. The performance of the proposed feature to classify the normal and abnormal cells show promising performance with accuracy of classification from all classifiers is more than 93%.
