In summer 1987 most of the multibody dynamics community met at the JPL, Pasadena, to discuss the needs and the open problems in multibody system simulation, especially for space applications. P. W. Likins stated in his survey [16]: “Computational questions focused initially on the selection of subroutines for numerical integration, matrix inversion, or eigensystem analysis,and lately have shifted
The analytical method by which macroscopic and above all microscopic traces of wear are studied, in order to reach conclusions about how flint tools were employed, has been applied with varying success in western archaeology since the 1960s. Two main approaches can be distinguished, where each approach examines somewhat different wear traces using different microscopic equipment. The scanning elec

In industry–academia collaboration projects, there are many issues related to different time horizons in industry and academia. If not adressed upfront, they may hinder collaboration in such projects. We analyze our experiences from a 10 year industry–academia collaboration program, the EASE Industrial Excellence Center in Sweden, and identify issues and feasible practices to overcome the hurdles
This paper provides the first regional econometric decomposition of CO2 emissions from fuel combustion in eight regions of the world. Using the best publically-available time series data (1971–2011), the analysis examines the key determinants and relationships of the ‘Green Energy Economy’ (GEE) in Africa, Asia, Latin America and the Caribbean, the Middle East, Non-OECD Europe and countries from t
The main objective of software inspection is to detect faults within a software artifact. This helps to reduce the number of faults and to increase the quality of a software product. However, although inspections have been performed with great success, and although the quality of the product is increased, it is difficult to estimate the quality. During the inspection process, attempts with objecti
Fracture from a straight crack under mixed mode loading conditions and small scale of yielding is studied. It is assumed that crack growth occurs in either mode I or mode II. Comparison of theoretically obtained values of the mode I stress intensity factor at incipient kinking with experimental results indicates that mode I is preferred to mode II when the loading is such that the crack surfaces a
