The scope of this paper and the aim of proposed model were to apply monetary Input –Output (I-O) analysis to point out the importance of reusing know-how and other requirements in order to reduce the production costs in a manufacturing process for a laptop computer. I-O approach using the monetary input-output model is employed to demonstrate the impacts of different factors in a manufacturing ...

Students often have their own individual laptop computers in university classes, and researchers debate the potential benefits and drawbacks of laptop use. In the presented research, we used a combination of surveys and in-class observations to study how students use their laptops in an unmonitored and unrestricted class setting—a large lecture-based university class with nearly 3000 enrolled s...

In this paper we report on the current state of the newly established Princeton Laptop Orchestra (PLOrk), a collection of 15 meta-instruments each consisting of a laptop computer, interfacing equipment, and a hemispherical speaker. Founded in the fall of 2005, PLOrk represents the first laptop ensemble of its size and kind, and brings together many of our research and aesthetic interests as mus...
