  2. 1. Enabling Test Automation for Industrial PLC Programs

    Author : Mikael Ebrahimi Salari; Eduard Paul Enoiu; Wasif Afzal; Cristina Seceleanu; Jee Eunkyoung; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PLC; PLC Testing; Automated Testing; PyLC; EARS Syntax; FBD; ST; Computer Science; datavetenskap;

    Abstract : Testing safety-critical systems, particularly those controlled by Programmable Logic Controllers (PLC), is crucial for ensuring the safe and reliable operation of industrial processes. This thesis addresses the critical need for automated testing of safety-critical PLC systems used in various industrial settings. READ MORE

  4. 2. A Simulation-Based Optimisation Method for PLC Systems

    Author : Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation based optimisation; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Parameter tuning; Optimisation methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Tuning of process parameters such as time constants, cam values, velocities and robot paths, in order to increase capacity utilisation, is today a challenging manual on-line task in many automated manufacturing systems. On-line methods interfere with production and will cause unwanted downtime, which indeed reduces capacity utilisation. READ MORE

  5. 3. Reliable Virtual Commissioning

    Author : Henrik Carlsson; Bengt Lennartson; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Virtual commissioning; Simulation based PLC control code verification; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Virtual commissioning is a technique for programming, optimising and verifying industrial automated production, such as robot controllers and programmable logic controllers (PLC), off-line in a simulated environment. Compared with traditional robot off-line programming and simulation, the scope is wider and can include an entire production cell. READ MORE

  6. 4. Regulation of Phospholipase C and Plasma Membrane Phosphatidylinositol 4,5-bisphosphate in Insulin-Secreting Cells

    Author : Sophia Thore; Anders Tengholm; Erik Gylfe; Peter Jones; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell biology; PLC; PIP2; insulin-secreting cell; Ca2 ; evanescent wave microscopy; phosphoinositide kinase; ATP ADP ratio; Cellbiologi; Cell biology; Cellbiologi;

    Abstract : The membrane phospholipid phosphatidylinositol 4,5-bisphosphate (PIP2) is an important signaling molecule as substrate for the phospholipase C (PLC)-catalyzed formation of inositol 1,4,5-trisphosphate (IP3) and diacylglycerol, and by directly regulating e.g. ion-channels, the cytoskeleton and vesicle trafficking in various types of cells.

  7. 5. Effects of ethanol on muscarinic acetylcholine receptors in nerve cells

    Author : Murielle Hellsten Caron; Institutionen för laboratoriemedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Klinisk kemi; Clinical chemistry; nerve cell; SH-SY5Y; NOS; PKC; PLC; Ethanol; mAChR;

    Abstract : This thesis focused on the mechanisms involved in the effects of long-term ethanol treatment on mAChRs and their coupled-signal transduction pathway in human neuroblastoma SH-SY5Y cells. All 5 subtypes of mAChRs were expressed in these cells. READ MORE
