Lean Manufacturing
Abstract: An important goal of lean manufacturing is to speed up response times from suppliers and consumers as well as times spent in the production system. It has a tight relationship to another idea known as just-in-time manufacturing (JIT manufacturing in short). Just-in-time manufacturing prioritises productivity, effectiveness, and waste reduction for the producer and supplier of goods in an effort to match output to demand by only supplying items that have …

Ferromagnetism in Rare Earth Metal Doped ZnO: A Theoretical Approach
Abstract: The ferromagnetic properties of Diluted Magnetic semiconductor, Zn1−xDyxO is studied from theoretical point of view. The Heisenberg’s and Greens theorem determine the Hamiltonian of the system. The interaction between the nearest neighboring spin is determined by retarded Greens function. By using Greens theory, defect-induced ferromagnetism is discussed. For the ferromagnetic states, the expected exchange integral is positive and negative for the antiferromagnetic states. In addition, from magnetic property, the temperature …
