Diversity management in a technological context : a case study

Chasi, Samia 24 November 2011 (has links)
M.Phil. / In this study, diversity management is introduced as an issue of global concern. Based on the assumption that diversity, if well-managed, can be beneficial to organizations, a positive approach to diversity is strongly supported. Diversity management has an important role to play in South Africa for mainly two reasons. Firstly, because of South Africa's rich cultural history and apartheid legacy, diversity management issues arise as a concern more often than in other countries. Secondly, due to apartheid, South Africa was internationally isolated for many years, which gives issues around global competitiveness even more significance. In the South African context, the engineering sector is regarded as a motor for the country's development, in which the management of diverse workforces is highly relevant. This has to be seen in light of a serious challenge facing the sector, where diversity management requirements have to be reconciled with a skills shortage that seems to afflict the engineering sector in particular. All of these issues are illustrated by a case study. The practice of diversity management in Siemens South Africa serves to demonstrate that diversity management in South Africa is clearly centred on the contexts of race and race relations. Furthermore, the case study presents a comprehensive example of how a diverse workforce can be managed in a South African engineering company.

New control systems for aging SIEMENS cyclotrons

Playle, D. D. January 2015 (has links)
Introduction When properly maintained, cyclotrons often remain in operation for 20 years and more. However, as the years pass the control systems in particular become challenging to support. The I/O cards and other hardware eventually become obsolete, making spare parts difficult or even impossible to find. And the knowledge and ability to reload and configure the software also gets lost as operating systems and media storage technology change. This obsolescence is true of the Siemens RDS-112 cyclotron, which is controlled using a 486 computer, connected to an external STD card rack containing up to 15 I/O cards. These I/O cards were last manufactured in the 1990’s, and the iRMX-based control programs malfunction on computers newer than a 486 processor. A control system upgrade for the RDS-112 cyclotron has been developed by PET Technical Consulting Inc. This commercially available control system reduces operator training time, requires less maintenance, and supports new targets and custom product processes. Material and Methods The availability of high channel count I/O cards, and the decision not to support the old CPCU synthesis units, means the entire STD card rack can be replaced with 5 National Instruments (NI) I/O cards. The replacement computer is an industrial grade rack mounted PC with RAID 1 mirrored pair hard drives in front panel access quick swap bays. Two NI PCI-6509 Digital I/O cards connect directly to the RDS electronics, channel assignments are mapped using software configuration. Three NI PCI-6229 Multifunction I/O cards connect to the RDS electronics through a cable breakout interface plate, the terminal blocks are wired as needed to map the channels. The new control software was created using National Instruments LabVIEW. The new control sequences have a core based on the original RDS-112 FORTRAN control programs. Then hundreds of improvements were made to simplify operation, increase flexibility, minimize user involvement and mistakes, and clearly display key parameters and fault conditions. System control has been combined into a comprehensive Graphical User Interface, with controls and indicators grouped together onto subsystem pages. Commands that once needed to be typed-in have been replaced with a clickable control for each function. Bar graphs display target and slit currents. Status is obvious with red faults against normally green indicators. Audio alarms cue the operator for process interaction, warn if target current or pressure drifts from setpoint, or if faults occur with power supplies, vacuum, or water cooling. Improvements in sequences and beam algorithms have reduced the time to achieve full beam on dual targets from 10 minutes down to 3 minutes. Results and Conclusion This new control system has been installed on (5) five RDS-112 cyclotrons used for commercial isotope distribution. The total combined operation time of these systems after receiving the upgrade is now over 17 years, during this time the control system operation has been nearly problem free. UPDATE: The Siemens RDS-111 cyclotron is controlled by a VME computer that is now end-of-life. The VM30 and VM42 CPU boards and many of the I/O modules are no longer manu-factured. PET Technical Consulting is developing a control system replacement for the RDS-111 cyclotron with expected completion in 2014.

Automated process of morphing a CAD geometry based on a measured point cloud

Augustsson, Rasmus January 2019 (has links)
As part of the quality process and to assure that the product meets all geometric requirements, the produced part is measured and compared to the nominal geometry definition. If the part deviates outside given tolerances, there is a need to understand the effect on aero performance and mechanical function. Hence, a new analysis model must be created that reflects the produced shape and form of the product. The current procedure for measuring the part is to use white light scanning equipment to analyze the deviation with the scanning software GOM™. The analysis model is then created using Space claim™ and is meshed and analyzed using Ansys™ software. The objective with this thesis is to investigate the capabilities within Siemens NX™ to automate the procedure as there is a need to be more efficient and reduce lead-time.The Design Research Method is used to develop the automated procedure. This is a systematic method that identifies the task, presents possible solutions to that task and then evaluates those solutions. That workflow is repeated until a satisfying solution is found.It is found that it is possible to create an automated procedure in Siemens NX. This automated procedure requires no user interaction while running, so the lead-time is drastically reduced. The automated procedure morphs the nominal geometry to create a new surface with better resemblance to the scanned geometry. About 90% of the original surface area is outside a tolerance of 0.1mm, after the automated procedure the new surface has about 90% of the surface area inside a tolerance of 0.1mm.The limiting factor for the procedure is the skill of the developer and not the capability of the software. Therefore it is thought that the procedure could be improved to create a surface completely inside the specified tolerance, given that a more skilled developer refines the procedure.

Aspects of the choice of sampling frequency in the control system of a gas turbine

Öijerholm, Mikael January 2009 (has links)
<p>At Siemens, plcs are used to control the gas turbines, and to execute the code in the plcs cyclic interrupts are used. If the execution time for the interrupt becomes close to the cyclic time of the interrupt the load of the plc increases. High load levels can lead to situations were segments of code are not executed on time or even not executed at all. In this thesis an analysis of the regulators used to govern a gas turbine has been performed. The purpose of the analysis is to study the performance of the regulators for different cycle times with the aim to be able to reduce the load by sampling more slowly.</p><p>To determine the load contribution from each regulator a review of the regulators and their execution times has been made. For the analysis the Matlab program Simulink has been used to make models of the regulators, which have then been sampled at different rates. With this information it is possible to determine for which cycle times each regulator has accepetable performance and how much load each regulator contributes with. A save of load of approximately 2 percent can be obtained without loosing too much performance.</p>
