April 15, 2005 some time ago i wrote about academic spam and the barrage of emails that we receive for bogus or dubious conferences. A group of students at the computer science and artificial intelligence laboratory at mit have created scigen. An automated computer science paper generator that they’ve used to submit paper proposals successfully! to such conferences.

The tool takes a set of author names and generates a professional looking academic paper, complete with abstract, graphs, and references see an example . Scigen an automatic cs paper generator scigen is a program that generates random computer science research papers, including graphs, figures, and citations. It uses a hand written context free grammar to form all elements of the papers.

One useful purpose for such a program is to auto generate submissions to conferences that you suspect might have very low submission standards. A prime example, which you may recognize from spam in your inbox, is sci/is and its dozens of co located conferences check out the very broad conference description on the wmsci 2005 website. Using scigen to generate submissions for conferences like this gives us pleasure to no end. In fact, one of our papers was accepted to sci 2005! see examples for more details. Want to generate a random cs paper of your own? type in some optional author names below, and click generate.

Emre karagozler disney research pittsburgh we present a new energy harvesting technology that generates electrical energy from a user’s interactions with paper like materials. The energy harvesters are flexible, light, and inexpensive, and they utilize a user’s gestures such as tapping, touching, rubbing and sliding to generate energy. The harvested energy is then used to actuate leds, e paper displays and other devices to create interactive applications for books and other printed media. Paper generators are based on electrets: materials that hold quasi permanent electric charge.

Our implementation makes use of ptfe polytetrafluoroethylene sheets, commonly known by the brand name teflon. When the ptfe sheet is rubbed with ordinary paper, opposite polarity charges accumulate on the surfaces of the paper and the ptfe due to the triboelectric effect, forming the electret figure a. Because ptfe has a lower electron affinity than paper, charge on the ptfe is negative. When the ptfe sheet is stacked with conductive layers that serve as electrodes, such as silver coated polyester sheets or paper with printed conductive ink, the charge on the ptfe attracts free charges of opposite polarity, which then accumulate on the surface of the conductors, as shown in figure b. The operation of the paper generators relies on the movement of the two conductive sheets relative to each other and the electret, ptfe.

As the relative positions of the sheets change, the distribution of the induced charges, the electric field, and the total capacitance between the conductors change, resulting in an electric potential difference between the conductors figure c. Hence, the movements of the sheets and the field source are converted into electrical potential energy that can do work. The same principle of operation applies to the horizontal movement of the top electrode sliding. In this scenario, the user holds and rubs the ptfe sheet on and off the bottom electrode, while touching the other end of the voltmeter with his free hand. These different paper generator configurations and structures allow for energy generation using different user gestures, such as tapping, rubbing, touching, rotating and sliding. When a user taps a button made out of paper, harvested energy lights up leds placed at the rockets engine and the stars. The underside of the button is made out of silver coated polyester, and it is separated from the bottom sheets by black foam rubber.

E paper displays are an especially suitable application for paper generators since they require high voltages but very little power. Here, when the user creates energy by using a rubbing paper generator, a pattern on the e paper display shows a cats face. When the user turns the rotating top electrode, harvested energy lights up and led.

Similar structures, where the top electrode slides instead of rotating, can be easily implemented. When a user presses the button, a voltage difference is created between the top and bottom sheets of the paper generator. When the user rubs the paper generator, a passive circuit allows for the characters h e l l o to be displayed sequentially, creating an animation. paper builder the paper generator is the one amp only software for setting examination question paper. The software performs all tasks related to paper setting, starting from preparing question bank to printing paper and answer key.
