PT-AE900U
In a controlled lighting room,
I would like to have a 120" screen.
In what instance will the picture be best?
14 feet (ceilling mounted) Zoomed to 120" OR 20 Feet away fro 120" screen size : No Zoom?
Will using an Optical Zoom of 2x make any image difference?
Brightness and Clarity im assuming being the variables?
Thanks
The PT-AE900U is an excellent 720P projector. You can get a 120" image from as close as 12' using 2X zoom. 120" without zoom will require a 24.3' distance from the screen. I have a Sharp XV-Z9000U projector and I am using approx. 1.30 zoom. I really couldn't see much of a difference in image quality using the zoom. The picture with no zoom may be slightly better, but it's very minimal. Light control is the biggest variable with a front projector. If you have a light controlled room, you should be good to go. Check out the link below for a projection calculator compliments of projectorcentral.com. It will tell you anything you need to know.
This book deals with the study of quantum communication protocols with Continuous Variable (CV) systems. Continuous Variable systems are those described by canonical conjugated coordinates x and p endowed with infinite dimensional Hilbert spaces, thus involving a complex mathematical structure. A special class of CV states, are the socalled Gaussian states. With them, it has been possible to implement certain quantum tasks as quantum teleportation, quantum cryptography and quantum computation with fantastic experimental success. The importance of Gaussian states is two fold; firstly, its structural mathematical description makes them much more amenable than any other CV system. Secondly, its production, manipulation and detection with current optical technology can be done with a very high degree of accuracy and control. Nevertheless, it is known that in spite of their exceptional role within the space of all Continuous Variable states, in fact, Gaussian states are not always the best candidates to perform quantum information tasks. Thus nonGaussian states emerge as potentially good candidates for communication and computation purposes.

Normal adults do not have any difficulty in recognizing their homes. But can artificial systems do in the same way as humans? This book collects interdisciplinary evidences and presents an answer from the perspective of computing, namely, the theory of cognitive prism. To recognize an environment, an intelligent system only needs to classify objects, structures them based on the connection relation (not through measuring!), subjectively orders the objects, and compares with the target environment, whose knowledge is similarly structured. The intelligent system works, therefore, like a prism: when a beam of light (a scene) reaches (is perceived) to an optical prism (by an intelligent system), some light (objects) is reflected (are neglected), those passed through (the recognized objects) are distorted (are ordered differently). So comes the term `cognitive prism`! Two fundamental propositions used in the theory can be informally stated as follow: an orientation relation is a kind of distance comparison relation -- you being in front of me means you being nearer to my face than to my other sides; a pair of objects being connected means any object, precisely the space occupied by the object, can be moved to a place where it connects with the pair.

High Quality Content by WIKIPEDIA articles In objectOriented programming a member variable (sometimes called a member field) is a variable that is associated with a specific class, and accessible for all its methods. If there is only one copy of the variable shared with all instances of the class it is called a class variable or static member variable. If each instance of the class has its own copy of the variable, it is called instance variable. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F.

Camera question? Please!!!!!!!!!!!!!!!!!!!!!?
I badly need to find a digital camera under $500. But
It must have at least 10 times optical zoom. And burst mode and variable shutter speed would be nice. Dont care about what brand! Im willing to go around 600 i guess.
Canon Digital Rebel XT will be more in your price range and a great camera for the money.
