In this research the sensitivity analysis of the geometric parameters such as: length, thickness and width of a single link flexible manipulator on maximum deflection (MD) of the end effector and vibration energy (VE) of that point are conducted. The equation of motion of the system is developed based on Gibbs-Appel (G-A) formulation. Also for modeling the elastic property of the system the ass...

Remote Center Compliance (RCC) structure is a passive device for assembly. For round peg-in-hole insertion, the initial misalignments have the same possibility to occur at arbitrary direction and the applied load is concentrated on a radial plane. RCC with rotational symmetry property therefore is a desired design. How to design structures with this property is discussed and it is proved that c...

Using a randomized evaluation in Kenya, we measure health impacts of spring protection, an investment that improves source water quality. We also estimate households' valuation of spring protection and simulate the welfare impacts of alternatives to the current system of common property rights in water, which limits incentives for private investment. Spring infrastructure investments reduce fec...

The determination of the elastic property distribution in heterogeneous gel samples with a finite element based reconstruction scheme is considered. The algorithm operates on small overlapping subzones of the total field to allow for a high degree of spatial discretization while maintaining computational tractability. By including a Maxwellian-type viscoelastic property in the model physics and...

reservoir characterization plays an important role in different parts of an industrial project. the results from a reservoir characterization study give insight into rock and fluid properties which can optimize the choice of drilling locations and reduce risk and uncertainty. delineating hydrocarbon bearing zones within a reservoir is the main objective of any seismic reservoir characterization...

Abstract The paper studies the initial boundary value problem related to dynamic evolution of an elastic beam interacting with a substrate through elastic-breakable forcing term. This discontinuous interaction is aimed model phenomenon attachment-detachment occurring in adhesion phenomena. We prove existence solutions energy space and exhibit various counterexamples uniqueness. Furthermore we c...
