Most enterprises are struggling to change their existing business processes into agile, productand customer-oriented structures to survive in the competitive and global business environment. Among their endeavor to overcome the obstacles, one of the frequently prescribed remedies for the problem of decreased productivity and declining quality is the automation of factories (Zhou & Venkatesh, 19...

In this research would try to give contribution for researchers or academics about simulation of the railway signaling system. The model system was built using miniature track and train model. Small LED used as a lamp signal. Point machine moved by servo motor controlled Arduino Nano. last, circuit replaced proximity sensor IR transceiver. result showed that could do some basic task which is oc...

This paper proposed the design method for an automated assembly lines, for carrying out basic design using threedimensional computer graphics (3DCG).It also proposes a method for performing kaizen and evaluation of automated systems utilizing hierarchic structure diagrams, state transition diagrams, improved tooling flow diagrams, a method for creating a Ladder Logic Diagram(LLD).Using a time P...

The gluonic field created by a static quark anti-quark pair is described via the AdS/CFT correspondence by a string connecting the pair which is located on the boundary of AdS. Thus the gluonic field in a strongly coupled large N CFT has a stringy spectrum of excitations. We trace the stability of these excitations to a combination of large N suppressions and energy conservation. Comparison of ...

The implementation of a low-cost FATEK PLC-based three-floor lift system is described in this study. Elevator systems are critical for vertical mobility buildings, and their control methods have been revolutionized by the use programmable logic controllers (PLCs). To motion lift, we DC geared motor. In example, push buttons used to direct elevator desired floor. scenario, ladder diagram program...

Early Programming Logic Control (PLC) were designed to replace relay logic systems. These PLCs were programmed in “Ladder Logic”, which strongly resembles a schematic diagram of relay logic. Programming logic control has several features like protection from the open area conditions such dust, heat and cold. PLC also has the ability to arrangement the inputs/outputs. It has low cost compared wi...

This paper presents a preliminary study of an approach that models programmable logic controllers (PLCs) for their effective deployment in industrial control processes. A working model is developed for automatic allocation of PLCs and also a formal verification of Ladder Diagram representations of control processes using the Symbolic Model Verifier (SMV) tool. Automatic resource allocation is a...

The phase diagram in temperature and magnetic field of the metal-organic, two-leg, spin-ladder compound (C5H12N)2CuBr4 is studied by measurements of the specific heat and the magnetocaloric effect. We demonstrate the presence of an extended spin Luttinger-liquid phase between two field-induced quantum critical points and over a broad range of temperature. Based on an ideal spin-ladder Hamiltoni...

The Supervisory Control Theory is applied to a manufacturing cell commanded by a programmable logic controller (PLC). By means of local modular approach a methodology that exploits modularity of the plant and of the behavioral specifications models optimal supervisors are obtained without state-space explosion. For the purpose of simplifying the ladder diagram implementation in the PLC, reduced...

-A novel method of detecting faulty bottles in a bottle filling industrial process has been proposed in this paper. Here we analyse the simulation study of one programmable logic controller (PLC) based control system by building up a program using ladder diagram and different addressing modes of SIEMENS PLC. This paper also presents comprehensive simulation of the performance of the different s...
