  1. 11. Small Scale Monoclonal Antibody Purification Platform

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Eric Nielsen; [2022]
    Keywords : PURIFICATION; MONOCLONAL ANTIBODIES; ÄKTA PURE; ÄKTA XPRESS; Chemistry;

    Abstract : The aim of this project is to transfer and implement a monoclonal antibody purification process that is traditionally done on an ÄKTAxpress to another machine called the ÄKTA pure. This is due to the fact that the ÄKTAxpress is being discontinued by the manufacturer and a replace-ment machine is needed for the time being. READ MORE

  3. 12. Dynamic Modeling of Target's Cooling Systems

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Maximilian Cahlin; [2021]
    Keywords : Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

    Abstract : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. READ MORE

  4. 13. Braking with a Directional Control Valve in a Hydraulic Open-Loop Transmission

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : Jonathan Karlborg; Emil Sten; [2021]
    Keywords : Directional Control Valve DCV ; Open-loop Hydraulic Transmission; Brake function;

    Abstract : This project presents an investigation if natural braking characteristics could be achieved on an open-loop hydraulic transmission without a brake valve. The goal with the simplified system was to utilize the directional control valve to achieve similar functionality as the brake valve does in the conventional system. READ MORE

  5. 14. A Component-based Model of a Fuel Cell Vehicle System

    University essay from Linköpings universitet/Fordonssystem

    Author : David Salomonsson; Erik Eng; [2021]
    Keywords : Fuel; Cell; Fuel cell; Energy; Efficiency; Powertrain; Control; Propulsion; Battery; Supercapacitor; Capacitor; Compressor; PEMFC; Hydrogen; Nitrogen pollution; Purge valve; Compressor; Throttle; Humidifier; Fuel cell model; Matlab; Simulink; Model; Emissions; PEM;

    Abstract : Improving the efficiency and performance of vehicle propulsion systems has always been desirable, and with increasing environmental awareness this has become increasingly topical. A particularly strong focus today is at fossil-free alternatives, and there is a strong trend for electrification. READ MORE

  6. 15. Model-Predictive Control of Gas Exchange in a Gasoline Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : George Jajji; [2021]
    Keywords : Control Engineering; Model Predictive Control; MPC; Gasoline Engine; Gas Exchange;

    Abstract : The process to induct air into engine cylinders, via the air inlet system and cylin-der port valves, is referred to as the "gas-exchange". Control is achieved by theturbo-charger, the intake throttle plate and the variable valve timing (VVT) sys-tem. These actuation systems traditionally use separate control with indepen-dent SISO feedback. READ MORE
