An improved design for acoustic particle separation in multichannel chips is presented. By wavelength matching of the microfluidic channel widths and the width of the interlacing bulk silicon, a well tuned resonating multilayer system can be accomplished. The acoustically tuned microchip offers considerable improvements in regards to particle focusing performance, i.e. separation efficiency, at fi
A simple second order feed-forward disturbance attenuation problem is analyzed. The problem has one free parameter, the control weight ρ in the loss function. It is found that controller structure and uniqueness for H∞-control, in the optimal case, changes when ρ is varied. Sensitivity to initial conditions is also drastically changed. The example is simple enough to allow a solution by formula ma

Most furniture produced in a temperate climate, such as in Europe, does not have a long service life in warm and humid conditions. This means it is difficult to purchase furniture from temperate climates for export to tropical countries. This report discusses the problems and gives recommendations on how to choose materials and types of furniture construction for humid conditions. Wood and wood
