Fossils and Strata is an international series of monographs and memoirs in palaeontology and biostratigraphy, owned by, and published on behalf of, The Lethaia Foundation in cooperation between the Scandinavian countries. Fossils and Strata forms part of the same structured publishing programme as the international journal Lethaia and provides a complementary outlet for more comprehensive systematic and regional monographs, including taxonomic descriptions. Fossils and Strata also offers the publication of thematic special issues comprising a series of shorter contributions.

The Concept of Labor in Islam

By: Khalil Ur Rehman

The working class in developed societies of the world evidently plays a dominant role in developing the economics of any society. They also know of their rights and responsibility as they respectfully play the role in toning and maintaining their economy. Likewise, the Islamic Society recognizes the dignity of labor at every step. Those who have no role, through refusal, in the strength of the country’s development have been admonished by Islam and strictures have been passed against them. This release probes deeper into the Islamic philosophy of labor and rights. The Concept of Labor in Islam covers the following areas: rules and regulations regarding labor, government servants, labor organizations, the status of a worker in Islamic society, the responsibility of the government, children’s rights and women’s status in Islam, Islam and capitalism, Islam and socialism, and reasons for failure. This book is one of the most comprehensive published materials on Islam and labor. It strengthens the establishment of the Islamic society by empowering the labor force.

Dynamics of Parallel Robots

From Rigid Bodies to Flexible Elements

By: Sébastien Briot,Wisama Khalil

This book starts with a short recapitulation on basic concepts, common to any types of robots (serial, tree structure, parallel, etc.), that are also necessary for computation of the dynamic models of parallel robots. Then, as dynamics requires the use of geometry and kinematics, the general equations of geometric and kinematic models of parallel robots are given. After, it is explained that parallel robot dynamic models can be obtained by decomposing the real robot into two virtual systems: a tree-structure robot (equivalent to the robot legs for which all joints would be actuated) plus a free body corresponding to the platform. Thus, the dynamics of rigid tree-structure robots is analyzed and algorithms to obtain their dynamic models in the most compact form are given. The dynamic model of the real rigid parallel robot is obtained by closing the loops through the use of the Lagrange multipliers. The problem of the dynamic model degeneracy near singularities is treated and optimal trajectory planning for crossing singularities is proposed. Lastly, the approach is extended to flexible parallel robots and the algorithms for computing their symbolic model in the most compact form are given. All theoretical developments are validated through experiments.
