Under the conditions of the pseudospin and spin symmetry, approximate analytical solutions of the Dirac-Morse problem with Coulomb-like tensor potential are presented. The energy eigenvalue equations are found and corresponding radial wave functions are obtained in terms of confluent hypergeometric functions. The energy eigenvalues are calculated numerically in the absence and presence of the tensor potential. We also investigate the contribution of the potential parameters to the energy splitting of the pseudospin and spin doublets. © 2011 Elsevier B.V. Source

International Journal of Adhesion and Adhesives | Year: 2012

Adhesive bonding is a key joining technology in many industrial sectors including the automotive and aerospace industries, biomedical applications, and microelectronics. Adhesive bonding is gaining more and more interest due to the increasing demand for joining similar or dissimilar structural components, mostly within the framework of designing lightweight structures. When two materials are brought in contact, the proper or adequate adhesion between them is of great importance, so it is necessary to device ways to attain the requisite adhesion strength between similar or dissimilar materials including the different combinations of metallic materials, polymers, composite materials and ceramics. To make adhesion possible, it is necessary to generate intrinsic adhesion forces across the interface. The magnitude and the nature of those forces are very important. From a thermodynamic standpoint the true work of adhesion (or intrinsic property) of the interface create free surfaces from the bonded materials. Adhesion mechanisms have been known to be dependant on the surface characteristics of the materials in question. The intrinsic adhesion between the adhesive and substrates arises from the fact that all materials have forces of attraction acting between their atoms and molecules, and a direct measure of these interatomic and intermolecular forces is surface tension. Atomic/molecular understanding of adhesion should be extremely beneficial in selecting or creating the appropriate materials to attain the desired adhesion strength. In the present paper, the following topics are reviewed in detail: (a) the surfaces or interfaces of similar and dissimilar materials, (b) adhesion or bonding mechanisms in the adhesive joints (c) thermodynamic theory of adhesion: surface tension or surface free energy concepts including the wetting, wetting criteria, wettability, and thermodynamic work of adhesion, (d) dispersion and polar components of surface free energies, and finally (e) effect of surface roughness on wettability or adhesion. © 2012 Elsevier Ltd.

In this paper, a new automated approach for the extraction of aboveground circular storage structures from near-nadir very high resolution satellite imagery is proposed. The approach focuses on the cast shadows of the circular structures and splits the boundaries of the shadow regions into curved segments using the chord-to-point distance accumulation technique. Thereafter, the curved segments are tested with newly developed constraints for being a part of a circular structure, and the ones that pass all of the constraints are considered as candidates. The reciprocal relations between the candidate segments are assessed by a developed mutual evidence test, and for the candidates that expose a relation, a robust circle fitting is applied. For the candidates having no such relations, an approach that further validates the circle evidence is developed. The approach consists in introducing regions-of-interest (ROIs) for each candidate segment and applying a circular Hough transform in each ROI, where the parameters of the transform are self-controlled. Experiments performed on 12 challenging Geoeye-1 test images selected from industrial areas reveal that the proposed approach accurately detects aboveground circular structures in complex industrial environments. Besides, the comparison of the results of the proposed approach with the results of two different circle detection approaches verifies the success and the robustness of the approach developed. © 1980-2012 IEEE.

This paper presents a study of the properties and behavior of cement mortar with clinoptilolite which is one of the most common zeolite minerals found in nature. Six mortar mixtures were prepared by replacing the Portland cement with 0%, 5%, 10%, 15%, 20% and 30% clinoptilolite by weight. Test results showed that water demand, soundness and setting times of the cement pastes increased with the increase of clinoptilolite content. Compressive and flexural strength of the mortars containing clinoptilolite were higher than the control mixture. Dry unit weight of the mortars with clinoptilolite was lower than the control mortar. Clinoptilolite replacement decreased water absorption and porosity of the mortars. The control mortar showed less durability to carbonation compared to the mortars made with clinoptilolite at the end of carbonation tests. Freeze-thaw resistance of the mortars containing 5% clinoptilolite was higher than control mortar. The effect of clinoptilolite incorporation on high-temperature resistance seemed to be dependent on amount of clinoptilolite, temperature level, and the cooling method. © 2010 Elsevier Ltd.
