    Summary:

    Leak detection and water loss control are important measures to improve efficiency in distribution systems and avoid unnecessary withdrawals. ‘Real’ water losses are defined as the amount of water lost between the supplier and the consumer, while ‘apparent’ losses are defined as those due to inaccurate consumption measurements by the consumer or utility.

    Summary:

  • Seawater stored in rock in Stockholm provides efficient district cooling

    Type: 
    Publication
    Publication date:
    Objective:

    With a water-filled rock chamber beneath Kungsholmen in Stockholm, the energy company Fortum has been able to substantially increase capacity in the city’s network for district cooling. The ordinary cooling plants can be phased out, and both high electricity needs and the risk of leakage of ozone-depleting substances will disappear along with them.

    Positive environmental and economic impacts

    • At full capacity, electricity consumption can be reduced by 45 GWh per year.

  • High Performance Forward Osmosis Membrane from Cellulose Acetate and Cellulose Acetate Derivatives

    Type: 
    Product

    The invention disclosure relates to a technology of membrane formulation and fabrication to produce membranes with high water flux and high salt rejection for FO applications based on cellulose acetate (CA) and its derivatives. The FO membrane of the present invention is for single-layer hollow fiber membranes but it is also applicable for dual-layer hollow fiber membranes. This results in a novel membrane with high performance and high packing density.

  • High Precision Carbon Dioxide Detection for Geological Reservoirs

    Type: 
    Product
    Technology:

    Background: Large-scale sequestration of carbon dioxide in underground geological reservoirs is being actively explored as a means to sustain fossil energy use and minimize climate risks. Assuring the integrity of the huge carbon dioxide plume sequestered in such underground reservoirs is central to the viability and acceptability of this approach. It is known that carbon dioxide can leak from underground storage reservoirs. The U.S. Department of energy has set a limit on carbon dioxide leak rates of 0.01 percent per year to the atmosphere.

  • Low Swing Dual Threshold Voltage Domino Logic Circuits

    Type: 
    Product

    Background: Domino logic circuit techniques have been extensively applied in modern high-performance microprocessors because of their superior speed and area characteristics as compared to static complementary metal oxide semiconductor (CMOS) circuits. However the domino logic gates frequently consume more dynamic switching power and display weaker noise immunity than static CMOS gates. Current aggressive circuit design which focus solely on enhancing circuit speed in microprocessors consume power levels that impose a limiting factor on system performance and functionality.

  • Low Swing Domino Logic Circuits Reduce Power Consumption in High-Performance Microprocessors

    Type: 
    Product

    Domino logic circuit techniques have been extensively applied in modern high-performance microprocessors because of their superior speed and area characteristics as compared to static complementary metal oxide semiconductor (CMOS) circuits. However the domino logic gates frequently consume more dynamic switching power and display weaker noise immunity than static CMOS gates. UW-Madison researchers have developed improved low-voltage swing techniques for simultaneously reducing the active and standby mode power consumption and enhancing the immunity to noise in domino logic circuits.
