The Combination of Extension of Ant Colony Algorithm and Other Intelligent Algorithms
Ma Li,Li Qianting,Ma Meiqiong,Meng Jun,Bai Jiyun 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.12
The extension of ant colony algorithm was proposed by Dorigo, the founder of ant colony algorithm, which is the latest ant colony algorithm for solving a continuous space optimization problem. Considering the blindness of man-made choice of initial solution and initial parameters of the algorithm, and according to the algorithm converging slowly and easily falling into local optimum, this paper has provided improvement strategy for this optimization. It has introduced quantum computing and genetic algorithm, chaos optimization to carry out combination and comparison, and it has carried out improvement on the weight internally solved by memory in the algorithm. The effectiveness of various combined algorithms was determined through the optimization of numerous multi-dimensional continuous functions.

Graphene Oxide Nanoplatelets Grafted Jute Fibers Reinforced PP Composites
Youxin Chen,Wenzhe Chen,Weikang Liang,Qianting Wang,Yu Zhang,Jianjie Wang,Changxin Chen 한국섬유공학회 2020 Fibers and polymers Vol.21 No.12
To improve mechanical and thermal properties of jute fibers (JFs) reinforced polypropylene (PP) composites, asurface treatment method by grafting graphene oxide nanoplatelets (GONPs) onto JFs was developed. The GONPseffectively enhanced the interfacial adhesion between JFs and PP matrix via improving mechanical interlocking. The resultsshow that PP/JFs-KH570-GONPs composites had the significant improvement of 16.2 % and 12.4 % in tensile and flexuralstrength, respectively. And the thermal property of PP/JFs-Silane-GONPs composites was also improved after treatment. These high performance composites have the potential to be applied in many fields, such as the automotive industry,household products and so on.

Life prediction and optimal design of flange structure of tire unloader
Jingxiu Ling,Wenjing Wang,Long Cheng,Qianting Wang,Hao Zhang 대한기계학회 2023 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.37 No.12
In the production process of the giant tire, the tire unloader needs to clamp and flip the tire, and the tire has a large inertia force, easy to cause vibration and lead to the failure of bearing parts, etc., then the flange is needed to play a fixed role. therefore, the rationality of flange design for the use of safety and service life are very important. For this reason, this paper simulates the flange connected to the tire unloader to obtain its stress history data, at the same time through genetic algorithm structure optimization analysis was carried out on the flange, it is concluded that the influence of structure parameters on the life of flange, and flange for structure optimization, get the optimized flange fatigue life 71 % increase compared to the original plan. The weight is reduced by 0.9 %, and the mechanical properties of the optimized flange are better.

Study of Pemetrexed-based Chemotherapy for Patients with Locally Advanced or Metastatic Cancers
Qian, Ting,Huang, Xin-En Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.11
Purpose: This study was conducted to observe the efficacy and safety of pemetrexed based chemotherapy in treating patients with locally advanced or metastatic cancers as first-line, second-line or third-line therapy. Materials and Methods: From May 2011 to January 2015, we recruited 29 patients with advanced breast cancer, 19 patients with advanced ovary cancer, 17 patients with advanced esophageal cancer,5 patients with advanced gallbladder cancer,5 patients with advanced cervical cancer and 1 patient with advanced tongue cancer in Jiangsu Cancer Hospital and Research Institute.All of them were pathologically confirmed and treated with pemetrexed based chemotherapy. After two cycles of treatment,efficacy and safety can be evaluated. Results: For pemetrexed based regimens,including 76 patients with 6 kinds of advanced cancer were considered eligible for inclusion. Complete remission represents CR, partial remission represents PR, stable disease represents SD, progressive disease represents PD. Among 29 patients with advanced breast cancer, 4 patients chose pemetrexed based regimens as second-line treatment,1 of them was PR,the other 3 got SD. The last 25 patients made use of this chemotherapy as third-line treatment, except one patient could not be assessed, 2 of them got PR,6 of them got SD,the remaining 16 of them finally were PD.19 patients with advanced ovary cancer,5 patients used this regimens as second-line treatment, 3 of them got PD,the remaining patients got SD, respectively. The last 14 patients made use of pemetrexed based regimens as third-line treatment,. RR (CR+PR) was 28.5%. Among 17 patients with advanced esophageal cancer, 2 patients made use of pemetrexed based regimens as first-line treatment,both of them got PR.4 of them used this chemotherapy as second-line regimen, except 2 patients could not be assessed,the remaining 2 was PD at last. The last 11 patients was third-line users, RR (CR+PR) was 18.2%. Among 5 patients with advanced gallbladder cancer, pemetrexed based regimens was used in 1 patient as first-line treatment and 1 patient as second-line treatment. The curative effect was SD and PD, respectively. 3 patients accepted pemetrexed based regimens as third-line treatment, 2 of them got PD as results and another was SD. Among 5 patients with advanced cervical cancer, just 1 patient adopted pemetrexed based regimens as first-line treatment, whose curative effect was PR.2 patients chose this chemotherapy regimens as second-line treatment. Both of them got PD as their consequence. The last 2 patients made use of the regimens as third-line treatment, the effect of them was PD and SD, respectively. The one who with advanced tongue cancer, pemetrexed based regimens was used as second-line treatment, and the consequence was PD. About 71.1% patients experienced bone marrow suppression. Among them, 5 patients reached 4 grade. Other toxicity of pemetrexed were neurotoxicity, fatigue, diarrhea, dysphagia and vomiting. No treatment related death occurred with pemetrexed-based treatment. Conclusions: Pemetrexed based chemotherapy has considerable effect in patients with advanced cancers such as breast cancer,esophageal cancer and ovary cancer. More randomly clinical trials are needed to verify the results.
