Introduction Normal color vision depends on the relative rates at which photons are absorbed in three types of retinal cones, which have peak sensitivities in different regions of the spectrum. The shortwave (S), middle-wave (M) and long-wave (L) cones are maximally sensitive near 430, 530 and 560 nm respectively. However, some 6% of men exhibit a variant form of color vision called deuteranoma...

starting from two-dimensional (2d) equations of motion, discretized formulations for transient behavior of soil-structure interaction problems have been derived. two different dynamic infinite elements taking into account single and two-wave types are presented in transformed space. by coupling the infinite elements with standard finite elements, an ordinary finite element procedure is used for...

In this paper we prove the propagation of singularities for the wave equation on differential forms with natural (i.e. relative or absolute) boundary conditions on Lorentzian manifolds with corners, which in particular includes a formulation of Maxwell’s equations. These results are analogous to those obtained by the author for the scalar wave equation [23] and for the wave equation on systems ...

The important characteristic of sea waves is their high energy density, which is the highest among renewable energy sources. Having up to 2700 km. of shoreline, Iran has a great potential in construction of offshore wave buoys (hereafter called OWB). In this article a OWB model with the possibility of assembling different buoy configurations is introduced. The system is exposed to regular and i...

Here we present experimental results that investigate the application of vibrotactile stimulus of pure and complex waveforms. Our experiment measured a subject’s ability to discriminate between pure and complex waveforms based upon vibrotactile stimulus alone. Subjective same/different awareness was captured for paired combinations of sine, saw, and square waveforms at a fixed fundamental frequ...
