The paper focuses on a new approach for the treatment of strain localization in solid materials. The theory is based on minimization principles associated with micro-Structure developments under the assumptions of a shear band of a zero thickness and the In summary, ten different DESs were successfully prepared from choline chloride and HBDs by a sim le process. Among these, three DESs made from choline chloride and HBDs (3-phenylpropionic acid uccinic acid, and ethylene glycol) have turned out to be potential DES-ethanol mixed solvents for the preparation of electrolytes in DSCs. Compared to c...

Finite element simulation of strain localization in inelastic solids by energy relaxationThe paper focuses on a new approach for the treatment of strain localization in solid materials. The theory is based on minimization principles associated with micro-structure developments under the assumptions of a shear band of a zero thickness and the presence of a mixed potential inside the shear band. Localization phenomena are regarded as...

Giải pháp bộ sạc thông minh tự động thích nghi tải ứng dụng trong hệ năng lượng mặt trờiTrong bài báo này, chúng tôi đã đề xuất một mô hình điều khiển sạc hiệu quả cho hệ pin mặt trời cả khi nguồn bức xạ mặt trời yếu. Kết quả thực nghiệm cho thấy mô hình đề xuất đã thu năng lượng mặt trời ở vùng bức xạ yếu cao hơn tới 70-80% so với bộ sạc truyền thống. Tuy nhiên, nghiên cứu chỉ mới dừng lại ở mô hình với tải là thuần trở. Hy vọng...
