RED Entertainment publisher Microsoft Game Studios distributor designer series engine version released vgrelease Japan JPN April 24, 2003 genre Pet raising simulation modes ratings platforms Xbox media DVD requirements input Headset N.U.D.E. Natural Ultimate Digital Experiment is a 2003 Xbox game, released only in Japan. It is a simulation style game in which the player assumes the role of tester for a new product. This product is a female humanoid robot called P.A.S.S. , or P ersonal A ssist S ecretary S ystem. This robot has only a very basic amount of functionality to start, and must be taught how to complete tasks. To accomplish this, the robot is issued voice commands by the player using the included headset, the Xbox Communicator. Information The game is similar in concept to the groundbreaking Sega Dreamcast game Seaman video game Seaman where you interact with an avatar via voice. The game includes a chat headset to interact with your new robotic girl. All communication is in Japanese, however several resources are available online to download translated guides and walkthroughs in English. N.U.D.E. never received an official release outside of Japan and import copies are very difficult to acquire. Only a handful are found on eBay each year, with copies in 2008 selling for an all time high of up to 150 shipping.

In Great Britain during the late 1840s through the 1850s, it was noticed that there was a reduced number of light colored European peppered moth s Biston betularia light color was most common and an increased number of the darker colored moths in the industry industrial areas. This led British ecologist Bernard Kettlewell to search for an explanation. The experiment During the late 1950s, Kettlewell began raising populations of light and dark peppered moths in his laboratory so he could perform his experiment. He marked all the moths with a drop of paint on the wings, so they could be recognized later. Next he released the light and dark moths in two separate wooded areas of England . One of the wooded areas was Birmingham wood near the city of Birmingham, which was very pollution polluted . The other wooded area was Dorset wood, which was in a farm area that was not polluted. At the end of this, Kettlewell set traps around the woods to catch the moths and see which populations survived in the two different areas. Peppered moths with the color of the trunks survived in the polluted areas where the trees were black the black moths thrived, and in the woods where the trees were light the light moths thrived. Conclusion Kettlewell concluded that the pollution from the factories in Birmingham created industrial melanism , which darkened the color of the woods. This in turn caused the moths with the recessive traits to have a better chance of survival because of the camouflage. So Kettlewell concluded that natural selection from industrial melanism caused the moths to adapt to their changing environment. References Johnson and Raven, George B. and Peter H.

orphan date September 2010 A remote experiment is a real experiment with real laboratory instrument s and equipment that can be controlled by a teacher or a student or any user from their computer through the Internet . Remotely controlled experiments have become a widespread tool for teaching physics at the university level of education . The use of a remote experiment is most beneficial and helpful in the domains where it is impossible to demonstrate the real experiment or where there is no appropriate equipment available. Advantages of remote experiments We can divide the physical experiment s into three fundamental groups. The first group consists of real experiments conducted in the traditional face to face School laboratory school laboratories . Working in the classical school laboratories provides a direct contact with real measure equipment and offers an immediate feedback of the teacher or the classmates. The second category of physical experiment comprises virtual experiment s conducted in Virtual laboratory virtual laboratories . Students do not work with real laboratory tool s in these laboratories, they only control virtual object s. The third group represents the real experiments that can be on line controlled by users via the Internet. A remotely controlled experiment or in short a remote experiment is used as a nomenclature for these kinds of experiments. Remotely controlled experiments have several benefits different from simulation s in virtual laboratories and from classical experiments in the traditional school laboratories carrying out experiments from anywhere in the world no time restriction experiment is permanently ready for measurement no danger of injury for the experimenter unique results for the particular place of measurement. noreferences date October 2011 External links http www.ictphysics.upol.cz remotelab index en.html http rcl.physik.uni kl.de DEFAULTSORT Remote Experiment Category Science experiments ... more details
A field experiment applies the scientific method to experiment ally examine an intervention in the real world or as many experimentalists like to say, naturally occurring environments rather than in the laboratory . Field experiments, like lab experiments, generally randomization randomize subjects or other sampling units into treatment and control groups and compare outcomes between these groups. Examples include Clinical trials of pharmaceuticals are one example of field experiments. Economists have used field experiments to analyze discrimination , health care programs, charitable fundraising , education , information aggregation in markets, and microfinance programs. Engineer s often conduct field tests of prototype products to validate earlier laboratory tests and to obtain broader feedback. History The use of experiments in the lab and the field have a long history in the physical, natural, and life sciences.

In economics, Peter Bohm, University of Stockholm, was one of the first economists to take the tools of experimental economic methods and attempt to try them with field subjects.
