In this paper, we demonstrate that a functional, portable device for the growth of bacteria or amplification of bacteriophage can be created using simple materials. These devices are comprised of packing tape, sheets of paper patterned by hydrophobic printer ink, and a polydimethyl siloxane (PDMS) membrane, which is selectively permeable to oxygen but non-permeable to water. These devices suppl...
Abstract. Though the level of machine digitization in flatbed-knitting (FBK) today is high, design and development knittable data sets are still currently very time-consuming, digital simulations methods calculation expensive insufficient terms accuracy fit technical properties. Knitting process retrofitting activities executed mostly manually by an operator on basis operator´s experience. This...
The results of ultrasonic tests are usually displayed as A-scan signals. In an A-scan signal, reflections of ultrasonic wave form different reflectors are shown as sharp echoes on a time by amplitude display. Interpretation of these echoes can sometimes be quite difficult and usually requires knowledgeable and experienced specialists. There exist other methods of displaying the ultrasonic test...
Many iterative learning control algorithms rely on a model of the system. Although only approximate model knowledge is required, the model quality determines the convergence and performance properties of the learning control algorithm. The aim of this paper is to remove the need for a model for a class of multivariable ILC algorithms. The main idea is to replace the model by dedicated experimen...
