    Abstract : What students should learn in school and therefore also what teachers should teach is an important issue worldwide. Mathematics teaching (and teaching in other subjects) is often regulated by some form of governing text in a written curriculum communcating a set of standards. READ MORE

  2. 2. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering

    Author : Björn Eriksson; Jan-Olov Palmberg; Jonas Larsson; Jochen Pohl; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid power; mode switch; energy efficient; independent metering; split spool; poppet; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. READ MORE
