  • Flow Control of Small Objects on Chip: Manipulating Live Cells, Quantum Dots, and Nanowires

    Page(s): 26 - 53
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (5448 KB)  

    This article is on microscale flow control, on dynamically shaping flow fields in microfluidic devices to precisely manipulate cells, quantum dots (QDs), and nanowires. Compared to prior methods, manipulating microscopic and nanoscopic objects by flow control can be achieved with simpler and easy-to-fabricate devices, can steer a wider variety of objects, and enables entirely new capabilities such as placement and immobilization of specific quantum dots to desired on-chip locations with nanoscale precision. A companion article investigates flow control in the body and develops methods to shape magnetic fields to direct ferrofluids of therapeutic magnetic nanoparticles to disease locations in patients.

  • Efficient Hydrogen Production for a Stationary Fuel Cell System: Two-Degree-of-Freedom Control of a Steam Reformer Unit

    Page(s): 54 - 69
    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (2405 KB)  

    This article focuses on an essential part of a stationary fuel cell-based power plant, namely the reforming unit that produces H2. The reformer is fueled by either CH4 or DME, depending on the catalyst. A detailed dynamic model of the reformer dynamics is derived, which takes into account the spatial distribution of system states such as temperatures and mass fractions. Parameters for the resulting model are identified and a modal transformation is applied to reduce computational complexity and enable comprehensible controller design. The inner loop of the cascaded controller aims at closely following a given H2 output trajectory. At the same time, the outer control loop keeps the CO output below a given maximum level, thus ensuring that only a minimum of climate relevant gases is exhausted. View full abstract»

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1993 KB)  

    The LEGO Mindstorms kit is widely used in many areas of education and research, covering a number of applications from benchtop demonstrations to postgraduate research, laboratories, and projects [1][3]. Although the kit was initially designed as a toy for children over 12 years of age, its use in university courses is increasing yearly. The kit has attracted the interest of people working in many areas, including artificial intelligence, embedded systems, control systems, robotics, and operating systems. The LEGO Mindstorms kit is inexpensive, easily reconfigurable, reprogrammable, versatile, and robust, which makes it well suited for use in teaching [4]. View full abstract»
