As touch screens become widely spread, making them more accessible to visually impaired people is an important task. Touch displays possess a poor accessibility for visually impaired people. One possibility to make them more accessible without sight is through gestural interaction. Yet, there are still few studies on using gestural interaction for visually impaired people. In this paper we pres...

We consider the Radon transform for a dual pair $(X,\Xi)$, where $X=G/K$ is noncompact symmetric space and $\Xi$ of horocycles $X$. address unitarization problem that was considered (and solved in some cases) by Helgason, namely determination pseudo-differential operator such pre-composition with extends to unitary $\mathcal{Q}\colon L^2(X)\to L_\flat^2(\Xi)$, $L_\flat^2(\Xi)$ closed subspace $...

In this research the free convection of a non-Newtonian between two infinite parallel vertical flat plates is investigated. The basic partial differential equations are reduced to ordinary differential equations which are solved analytically using Homotopy Perturbation Method (HPM). The comparison between the results from HPM and numerical method are in well agreement which proofs the capabilit...

The steady laminar stagnation point flow of an incompressible electrically conducting micropolar fluid impinging on a permeable flat plate with uniform suction/injection is considered. A uniform magnetic field is applied normal to the plate. The effect of viscous dissipation is taken into account. The governing partial differential equations are transformed into ordinary differential equations....

objectives: the purpose of this study was to compare the accuracy of implant position transfer and surface detail reproduction using two impression techniques and materials. materials and methods: a metal model with two implants and three grooves of 0.25, 0.50 and 0.75 mm in depth on the flat superior surface of a die was fabricated. ten regular-body polyether (pe) and 10 regular-body polyvinyl...

In this paper, the effect of elastic foundation on the out of plane displacement of functionally graded circular plates using differential transform method is presented. Differential transform method is a semi-analytical-numerical solution technique that is capable to solve various types of differential equations. Using this method, governing differential equations are transformed into recursiv...
