Abstract:
The theses is focused on the use of PLC technology. The aim of the thesis is creating device which communicates in a narrowband transmission frequency band. Transmission of communication between plc elements runs through the low voltage distribution network. The frequency and phase modulations are used in order to change the character of data signal. Transmitter and receiver parameters are subjects to the CENELEC standard. The theses gives more attention to the area of hardware build communication element rather than the area of programming.

Abstract:
The development and use of computerized machining tools and equipment within the manufacturing area has opened the door to an abundance of data. But, there is a need to structure the data, make it generic and accessible and define ways of communication in order to maximize the benefits of its utilization. The Line Information System Architecture (LISA) project aims to create an information architecture which aids in capturing and understanding this data by tackling the above mentioned requirements.This thesis is intended to implement the Tweeting machine concept, tweeting useful machining info

Abstract:
This Diploma thesis describes the procedure of setting the parameters of communication blocks and functions in PLC and PC, so that it is possible to remotely control part of the production process. TCP / IP protocol is used for communication between devices. Part of the production technology is represented by the created 3D model, which serves for three-dimensional interpretation of the simulation of the mathematical model of this part of the process. Part of this work is the design of this model and description of its dynamics.

The aim of this master's thesis was to create a design for a prototype of a mobile robotic platform and its physical fabrication. Another goal of this master's thesis was to develop a control algorithm and its implementation into a prototype. In addition, the thesis was extended by an autonomous motion mode, an algorithm for robot path planning, and the design of the Human Machine Interface (HMI). The introduction contains a description of some already created mobile robotic platforms, a presentation of the company B&R and the theory needed to understand omnidirectional mobility. The next chap

Abstract:
Eftersom Valmet inte har någon metod för att testa styrsystemen för transportörerna de levererar med sina balningslinjer går mycket tid åt till att felsöka på plats. De söker därför en metod som gör det möjligt att simulera styrsystemen för att hitta och lösa fel innan leverans. Tryckt litteratur och artiklar publicerade i vetenskapliga journaler har varit grunden till den studie som utförts under arbetet. Ett tillhandahållet styrsystem innehållande en typ av transportör har studerats för att få förståelse för dess funktion. För att simulera krävs en modell som representerar och uppför sig som

Syftet med studien har varit att analysera produktionsrelaterad teknik för att utveckla en kostnadseffektiv lösning för dataöverföring mellan maskinens styrsystem och trådlösa enheter. Anledningen till att trådlösa metoder valdes för arbetet var att kunna reparera de olika givarnas fel och att ingripa i sensorerna i realtid. Vid användning av en bärbar enhet måste felet repareras och testas på maskinen. Undersökningen innefattar även att utveckla en lämplig metod för att trådlöst överföra uppsamlade mätdata till serverns miljö där mätdata ska lagras för att kunna presentera senare diagram, tab

Abstract:
This research is focused on three food multiple retailers, Sainsbury plc, Tesco plc, and Safeway plc. The research is designed to explore the relationship between technology and strategy in these organisations. The currently held view among the researchers and managers of these organisations is that technology has a limited impact on the processes that formulate strategy, and as such may be regarded as having an enabling role. This thesis proposes that while this view may have been correct in the past it is so no longer, and that technology is not following strategy but leading strategy in the
