In this paper we describe how future office environments can benefit from the addition of weightless walls—virtual, sound blocking walls created using headsets. We particularly focus on exploring how different interaction techniques can be employed to efficiently create, erase, or edit the layouts of these walls, and envisioning how they could impact the overall office experience.

In the early 1980s, I used Stan Rosenschein’s functional language REX to servo Flakey’s two wheels to set points of speed and direction that were functions of sonar readings. This let Flakey drive along hallways with no dead reckoning or planning whatsoever. It seemed miraculous at the time; a situated automaton that knew things without needing any models. However, I thought of it as (sensor-dr...

The effect of utilizing superhydrophobic walls on improving the convective heat transfer in a rectangular heatsink has been studied numerically in this paper. The vertical walls were kept at isothermal hot-and-cold temperatures and horizontal walls were insulated. The boundary condition on the walls was: no-slip for regular, and slip (with slip length of 500 µm) for superhydrophobic walls. By c...

despite the rapid growth of engineering science especially in the modern structural engineering and application of new materials in civil engineering, a significant percentage of world population in different countries are living in adobe buildings made from mud-bricks. in this paper, by performing experimental study on scaled mud-brick walls under monotonic load, in-plane behavior of the walls...
