Let bd(P ) denote the boundary of a simple polygon P . Points p and q of P are mutually visible if segment pq lies entirely inside P . This notion of visibility gave birth to an extensive literature on art-gallery problems [3], concerned with guarding the floor of a polygonal art-gallery. Chvatal [2] showed that bn/3c point guards are always sufficient and sometimes necessary. Allowing guards t...

Given the growth of Internet photo collections we now have a visual index of all major cities and tourist sites in the world. However, it is still a difficult task to capture that perfect shot with your own camera when visiting these places, especially when your camera itself has limitations, such as a limited field of view. In this paper, we propose a framework to overcome the imperfections of...

Imagine that you are the owner of several art galleries and that you are in the process of hiring people to guard one of them. Unfortunately, with so many in your possession, you seem to have forgotten the exact shape of this particular one. In fact, all you can remember is that the art gallery is a polygon with n sides. Of course, guards have the capacity to turn around a full 360◦ and can see...

We introduce the notion of a normal gallery, a gallery in which any configuration of guards that visually covers the walls necessarily covers the entire gallery. We show that any star gallery is normal and any gallery with at most two reflex corners is normal. A polynomial time algorithm is provided deciding if, for a given gallery and a finite set of positions within the gallery, there exists ...

In this paper the simulation and design of a quantum-film electro-optic switch is considered. This photonic device, is made from a new organic dipolar material called MNA or 2-methyl-4 nitroaniline, which possesses a high merit in comparison with it's inorganic counterparts (e.g. LiNbO3, GaAs, InSb, Quartz, etc). Montecarlo method is used to simulate the photon-it-electron interaction in this m...

introduction patients with palliated congenital heart disease may present later in life for major, non-cardiac surgical procedures. although alternative surgical techniques are now available for the treatment of the transposition of the great arteries (tga), an atrial level baffle (mustard or senning procedure) was previously performed. long-term adverse effects of the atrial level switch inclu...

This paper presents an algorithm based on multi-objective approach for network reconfiguration. Multiple objectives are considered for reduction in the system power loss, deviations of the nodes voltage and transformers loading imbalance, while subject to a radial network structure in which all the loads must be energized and no branch current constraint is violated. These three objectives are ...

Introduction: Photo aging is significantly different from chronological aging in both clinical and histological appearances. It has been suggested that oxidative stress generated by ultraviolet radiation (UVR), leads to photo aging over a long time period. This study was conducted to determine the relationship between the indicators of plasma oxidative stress and photo damaged skin in patient...

This paper presents u-Photo which is an interactive digital still image including information of pervasive services associated with networked appliances and sensors in pervasive computing environment. U-Photo Tools can generate a u-Photo and provide methods for discovering contextual information about these pervasive services. Users can easily find out this information through the metaphor of ‘...
