The books Fractional Calculus with Applications in Mechanics: Vibrations and Diffusion Processes and Fractional Calculus with Applications in Mechanics: Wave Propagation, Impact and Variational Principles contain various applications of fractional calculus to the fields of classical mechanics. Namely, the books study problems in fields such as viscoelasticity of fractional order, lateral vibrations of a rod of fractional order type, lateral vibrations of a rod positioned on fractional order viscoelastic foundations, diffusion-wave phenomena, heat conduction, wave propagation, forced oscilla |

Sommario/riassunto |
|
This book, authored by Prof. Dr. Gerhard Albrecht, details the economic integration of displaced persons and refugees in the region of Hessen, Germany, following World War II. It examines the efforts made to incorporate these populations into the local economy through various stages of settlement and employment strategies. Utilizing statistical data from Hessen, the book provides a comprehensive analysis of the distribution and impact of displaced persons on local industries and the workforce. The author's purpose is to present an objective study of the socio-economic challenges and solutions related to the integration of displaced individuals in post-war Germany. The intended audience includes scholars and policymakers interested in social policy, economic integration, and post-war history. |
