The demand for janitorial robots has gone up with the rising affluence and increasingly busy lifestyles of people [1], both in offices and personal homes. All too often people forget to switch off lights, close doors, throw away garbage and so on; this is where a janitorial robot would come in handy. This kind of robot must have the necessary characteristics of being able to autonomously naviga...

Changing a scene's illuminant causes the chromatic properties of reflected lights to change. This change in the lights from surfaces provides spectral information about surface reflectances and illuminants. We examine conditions under which these properties may be recovered by using bilinear models. Necessary conditions that follow from comparing the number of equations and the number of unknow...

In this article I investigate why two shows from different television genres in countries resort to nearly identical costume choices convey villainy. argue that the directors, writers, and designers for US science fiction show Stargate SG1 BBC's Merlin use orientalist tropes of veil as exotic, oppressed or threatening costumes their non-Muslim characters because centuries-long association Weste...

Increasingly, our everyday environments become more and more connected and “smart”. Intelligent Interactive Systems (IIS) is an umbrella term to describe environments that are characterized by their ability to process data and generate responsive behavior using sensors, actuators, and microprocessors. Sentient Architecture generates an artful, imaginative, and engaging environment in which we c...

Ghasem Amin is known as a harbinger of women’s social and cultural rights in the world of Arabs. Primarily, he centered his ideas on three axes: a; women’s education to the primary level, B; necessity of women’s free will and decision making in issues like marriage, c; religious veil (covering all the body except the face and the two palms); although the outcomes of his ideas require more discu...

A common belief is that further quantum corrections near the singularity of a large black hole should not substantially modify the semiclassical picture of black hole evaporation; in particular, the outgoing spectrum of radiation should be very close to the thermal spectrum predicted by Hawking. In this paper we explore a possible counterexample: in the context of dilaton gravity, we find that ...

The human visual sensitivity to sinusoidal flickering light is generally band-pass tuned to temporal frequency, probably due to retinal physiological properties consist of low-pass and following high-pass filtering processes. It is also shown that the temporal sensitivity of visual cortex has a band-pass shape. Meanwhile, for the flickering lights with two or more frequency components, flicker ...
