The main advantage of this algorithm is its automatic selection of communities with high quality in a linear execution time.

In the present study, we developed a high dose rate brachytherapy treatment for superficial skin. For this purpose, we established an algorithm to deliver a uniform prescribed dose of 6 Gy to a flat surface using PHITS Monte Carlo code. In this treatment, the Cobalt-60 source is placed on the affected area of the skin through Harrison-Anderson-Mick applicator which contains five embedded catheters, in each, five dwell positions were activated. The dwell times, corresponding to the source stops, were optimized using the Tikhonov regularization and the L-curve methods in order to achieve the clinical goal of brachytherapy treatment, which is delivering 6 Gy uniformly over the affected area during the irradiation while keeping a constant distance under the skin. Therefore, the uniformity of the dose was observed in the 2D isodose curves and 3D isodose surfaces at the target distances from the plane of the active positions within the applicator and the prescribed dose was delivered to the affected area uniformly.","PeriodicalId":253361,"journal":{"name":"2020 IEEE 6th International Conference on Optimization and Applications (ICOA)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115615344","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}

The aging time of the precursor solution was optimized in order to perform a general study on the structural, optical and electrical properties along 72 hours. The increase of the aging time of the precursor solution showed the formation of films with three crystalline orientations (100), (002) and (101) corresponding to a wurtzite phase, and indicating a good crystallization of our films. It was also found that the increase of aging time led to an increase in surface roughness, in addition of that it can also increase the films thickness. From the optical properties results, we revealed a reduction in the optical transmittance of the films while aging the deposition solution, and the optical band gap increases from 3.175 to 3.224 eV. Concerning the electrical properties, the conductivity is limited by the mobility of charge carriers, also a maximum intrinsic conductivity of $3.61 (Omega . text{cm})^{-1}$ is obtained for films deposited at 24 hours of aging time of the deposition solution.","PeriodicalId":253361,"journal":{"name":"2020 IEEE 6th International Conference on Optimization and Applications (ICOA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123325500","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 order to analyze the tolerances in a statistical way we will integrate in this work the jacobian torsor model and the simulation of the monte carlo. The assembly in this model is subdivided into surfaces, we will base on The parameters of the small displacement rotor (SDT) in order to express the relative position between two surfaces of the assembly. From a surface graph and the Jacobian Torsor model, we can create a 3D dimensional chain. In the last step, we will analyze the tolerances statistically with the Monte Carlo method.
