2017 marks the 40 anniversary of the Rubik’s Cube (under its original name the Magic Cube). This paper-demonstration describes explorations of the cube as a performance controller for music. The pattern of colors on a face of the cube is detected via USB video camera and supplemented by EMG data from the performer to model the performer’s interaction with the cube. This system was trialed in a ...

The concept of zero-energy building (ZEB) has attracted global attention in recent years as it involves offsetting the primary energy usage a on an annual base by generated from renewable resources. performance wall-mounted photovoltaics (PV) for applications great potential ZEB. In this study, we compared and common roof-mounted PV systems using combination experimental theoretical studies. sy...

This paper covers the modeling and nonlinear attitude control of Cubli, a cube with three reaction wheels mounted on orthogonal faces that becomes wheel based 3D inverted pendulum when positioned in one its vertices. The proposed approach utilizes quaternions instead Euler angles as feedback states. A nice advantage quaternions, besides usual arguments to avoid singularities trigonometric funct...

Large channel capacity is achieved by MIMO (Multiple-Input Multiple-Output) technology with multi-antenna at the transmitting and receiving side [1]. Many studies to maximize the MIMO channel capacity have been performed, and measurements show that channel capacity is enhanced by directional antennas [2] and multi-polarization [3] in indoor environment. Various MIMO antennas with pattern and po...

We have built a Sinai cube to illustrate and investigate the scaling properties that result by iterating chaotic trajectories into a well ordered system. We allow red, green and blue light to reflect off a mirrored sphere, which is contained in an otherwise, closed mirrored cube. The resulting images are modeled by ray tracing procedures and both sets of images undergo fractal analysis. We offe...

The present study is designed to test the role of immersion and media content in the sense of presence. Specifically, we are interested in the affective valence of the virtual environments. This paper describes an experiment that compares three immersive systems (a PC monitor, a rear projected video wall, and a head-mounted display) and two virtual environments, one involving emotional content ...

Wall-mounted solar chimneys use radiation to heat the air inside chimney cavity and thermal pressure create natural convection. Applying this principle allows for indoor ventilation of a building without energy consumption. However, in wall-mounted designs, different inlet outlet design dimensions can have varying degrees impact on effectiveness ventilation. In order analyze internal airflow st...

seismic attributes are very useful in seismic data interpretation. one of these attributes is the coherency attribute. seismic coherency is a complex trace and a geometrical attribute that is applied to a 3d cube of seismic data. it is a measure of lateral changes in acoustic impedance caused by the variation in structure, stratigraphy, lithology, porosity, and the presence of hydrocarbons. whe...

This paper presents a time-accurate procedure for computing unsteady aerodynamic forces on wings with a full-span oscillating control surface by using sheared grids. In this procedure, the flow is computed by solving the unsteady Reynolds-Averaged Navier-Stokes (RANS) equations in conjunction with the one-equation Spalart-Allmaras turbulence model. A module to model control surface oscillations...
