Abstract: A method introduced by Lanczos for the approximate determination of fundamental eigenvalues of one-dimensional continuous systems is extended to permit the determination of higher eigenvalues as ...

Abstract: The precise control of a manipulator depends on its velocity as well as on its configuration and dynamic properties. This paper presents some observations that can serve as a useful tool for ...

Abstract: A number of well known methods of column analysis and their underlying reasoning are examined. A method of analysis is proposed which takes into account the reviewed literature. The method is ...

Abstract: General orthogonality relations which are valid for all linear elastic systems are derived, one relation for systems without damping and another for systems with viscous damping. A general ...

Abstract: In this paper, an approach that enables one to investigate and to reduce the mechanical couplings between the manipulator links is proposed. The presented method is based on equations of motion ...

Abstract: Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses (municipal, industrial, and ...

Abstract: The time it takes for deep percolation water from irrigated fields to reach underlying groundwater increases with decreasing particle size of the vadose zone material and increasing depth to groundwater. For average deep ...
