gender usually plays a significant role in the works of photographers andcauses men and women to take different photographs. nowadays, photographsand photography have a crucial and pivotal status in societies. the majority of theevents and accidents unfolding in various parts of the world are communicatedto the people via newspapers, magazines, internet and television, and undoubtedly,photograp...

Augmented reality on mobile phones has recently made major progress. Lightweight, markerless object recognition and tracking makes handheld Augmented Reality feasible for new application domains. As this field is technology driven the interface design has mostly been neglected. In this paper we investigate visualization techniques for augmenting printed documents using handheld Augmented Realit...

Negative diagonal magneto-conductivity/resistivity is a spectacular- and thought provoking-property of driven, far-from-equilibrium, low dimensional electronic systems. The physical response of this exotic electronic state is not yet fully understood since it is rarely encountered in experiment. The microwave-radiation-induced zero-resistance state in the high mobility GaAs/AlGaAs 2D electron s...

We derive an exact expression for the photocurrent of photo-emission spectroscopy using time-dependent current density functional theory (TDCDFT). This expression is given as an integral over the Kohn-Sham spectral function renormalized by effective potentials that depend on the exchange-correlation kernel of current density functional theory. We analyze in detail the physical content of this e...

In vitro tensile bond strengths of Photo Clearfil Bright (PB) and Clearfil Photo Posterior (CP) with Clearfil Photo Bond to human enamel and dentin were determined by a truncated cone bond test. Parameters tested were: four substrates (etched enamel; unetched dentin, D1; dentin conditioned with 10% polyacrylic acid, D2; and dentin etched with phosphoric acid, D3); two techniques (bonding agent ...

In the fall of 1913, while studying the photo-electric properties of freshly cut surfaces of the alkali metals in extreme vacua, we observed that immediately after first cutting, the fresh surface of sodium showed very large photo-sensitiveness when tested with monochromatic light of wave length 5461 A., even when the vacuum was of the order 10-6 mm. as measured by a McLeod gauge. But after sev...

This paper presents a census of 147 virtual agents, by examining and reporting on their physical and demographical characteristics. The study shows that the vast majority of agents developed are from a white ethnic background. Overall, female agents tend to be more photo realistic than their male counterparts who are more cartoon like. These findings highlight current stereotypes in relation to...

Amorphous Si/SiC photodiodes working as photo-sensing or wavelength sensitive devices have been widely studied. In this paper single and stacked a-SiC:H p-i-n devices, in different geometries and configurations, are reviewed. Several readout techniques, depending on the desired applications (image sensor, color sensor, wavelength division multiplexer/demultiplexer device) are proposed. Physical...

The data presented in this article are related to the research entitled of UV-A stable nanotubes. The nanotubes have been prepared from 3,5-bis(trifluoromethyl)benzylamine derivative of tyrosine (BTTP). XRD data reveals the size of the nanotubes. As-synthesized nanotubes (BTTPNTs) are characterized by UV-vis optical absorption studies [1] and photo physical degradation kinetics. The resulted da...
