  1. 21. Cow traffic in an automatic milking rotary system : with or without parallel guiding of cows for milking

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Lisa Pettersson; [2019]
    Keywords : parallel guiding; cow traffic; automatic milking rotary; cow behavior;

    Abstract : Automatic milking systems and automatic milking rotary systems (AMR) where the cows are gathered and held in a waiting area prior to milking are dependent on cows to enter the milking unit voluntarily. A low rate of cows that voluntarily enter the milking unit affects both the economy, working safety and cow health negatively. READ MORE

    Author : Erkan Dogantimur; Daniel Johnsson; [2019]
    Keywords : statistical; analysis; engine; gearbox; sensor; sensors; rotation; rotational; speed; differential; pressure; performance; characteristics; trueness; precision; accuracy; Hall; inductive; induction; gauge pressure; reference; hysteresis; bias; noise; linearity; non-linearity; DEWESoft; DAQ; wheel; tooth; teeth; absolute; rotary; encoder; matlab; XOR; Gray; binary; LabView; sampling; measurement; measuring; statistisk; analys; motor; växellåda; sensor; sensorer; rotation; rotationell; hastighet; fart; differentiell; tryck; prestanda; karaktäristik; trueness; precision; accuracy; noggrannhet; onoggrannhet; Hall; induktiv; induktion; tryckskillnad; referens; hysteres; bias; avstånd; brus; linjäritet; linearitet; olinear; olinjär; olinearitet; olinjäritet; DEWESoft; DAQ; sampling; mätning; hjul; tand; tänder; absolut; rotationsgivare; givare; matlab; XOR; Gray; binär; LabView;

    Abstract : This thesis provides a standardized method to measure accuracy for engine and gearbox sensors. Accuracy is defined by ISO 5725, which states that trueness and precision need to be known to provide a metric for accuracy. However, obtaining and processing the data required for this is not straight forward. READ MORE

  4. 23. Paddle stirrer to a reverberation chamber

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Andrea Mastrorilli; Josefin Holmgren; [2019]
    Keywords : paddle stirrer; reverberation chamber; control system; encoder; magnetic encoder; paddle-omrörare; modväxlande kammare; styrsystem; sensor; magnetisk sensor;

    Abstract : Halmstad University is currently equipped with an Echo-free chamber to perform EMC testing, but no reverberation chamber. The construction of a paddle stirrer to be utilized in Halmstad University would drastically reduce the time required to perform EMC testing, since reverberation chambers are more efficient than Echo-free chambers for these kind of tests.

  5. 24. Vibration analysis for predictive maintenance of a rotary pump : Optimal accelerometer configuration based on vibration analysis for cavitation detection of a bi-winged positive displacement pump

    University essay from KTH/Mekatronik

    Author : Gustav Osswald; [2019]
    Keywords : ;

    Abstract : Predictive maintenance based on condition monitoring uses sensor and system data to prevent damage, in advance to a failure occurring, allowing for a service to be performed at an optimal position in time. Condition based predictive maintenance estimates time of system failure based on a priori information, which has shown to be much more cost effective than traditional maintenance methods. READ MORE

  6. 25. Exploiting excited-state aromaticity for the design of efficient molecular motors : A quantum chemical study

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : André Engberg; [2019]
    Keywords : excited-state aromaticity; quantum chemical study; CIS; molecular motor;

    Abstract : In this work, a study of a recent approach in the design of light-driven molecular motors is presented. The approach involves enabling part of the motor to obtain aromatic-like properties through photoexcitation, and is found to significantly facilitate the rotary motion by reducing the barriers normally present in the excited-state potential energy surfaces of rotary motors.
