This master’s thesis delves into the field of space nulling interferometry, a promising technique for direct exoplanet detection and characterization. The work begins with an introduction to nulling interferometry, followed by a comprehensive theoretical background that lays the foundation for understanding the principles and limitations of this method. A review of previous space mission concepts, such as the Darwin mission, as well as currently existing ground-based facilities, highlight the advancements and lessons learned in the field throughout the years. This thesis aims in enhancing the understanding and application of nulling interferometry by the development in chapter 4 of an advanced analysis tool to assess interference quality. Coupling the results of the ray-tracing software CodeV and postprocess capabilities of MATLAB, this tool performs detailed tolerancing and sensitivity analysis, essential for optimizing the design and performance of future interferometric instruments. The tool was validated through a series of MonteCarlo simulations in chapter 5 and sensitivity analysis in chapter 6, demonstrating its effectiveness in identifying and mitigating potential sources of error.
The results underscore the importance of precise optical design, calibration, and correction mechanisms in achieving high-quality interference. This thesis provides a robust framework for future research and development in nulling interferometry such as precise tolerancing and optimisation of a nulling interferometer optical design, contributing to the ongoing quest for discovering and studying exoplanets.

In this book, I will discuss only the most common errors that appear on engineering drawings and the basic usage and understanding of the most frequently used drawings. All drawings will contain errors, but if you can eliminate many of those errors before the engineering design checker or your supervisor reviews your drawing, it will go through much easier. Your reputation is at stake! Your supervisor and the engineering design checker will see everyone's work and know their errors. They know your weak areas and who produces good work and who doesn't. It is helpful to know what they look for--or should be looking for.

Digital Twins in Industry is a compilation of works by authors with specific emphasis on industrial applications. Much of the research on digital twins has been conducted by the academia in both theoretical considerations and laboratory-based prototypes. Industry, while taking the lead on larger scale implementations of Digital Twins (DT) using sophisticated software, is concentrating on dedicated solutions that are not within the reach of the average-sized industries. This book covers 11 chapters of various implementations of DT. It provides an insight for companies who are contemplating the adaption of the DT technology, as well as researchers and senior students in exploring the potential of DT and its associated technologies.

Technology: general issues --- digital twin --- manufacturing --- tolerancing --- geometry assurance --- digital thread --- virtual reality --- augmented reality --- 360 modules --- YouTube --- online App --- construction --- building --- digital pedagogy --- role play --- e-learning --- risk management. --- internet of things --- interoperability --- standardization --- engine block --- industrial process --- steady state simulation --- directed graph --- piping and instrumentation diagram --- Balas® --- ergonomics --- production process --- Digital Twin --- digital twins --- crane --- machine design --- integration --- maintenance --- operation --- API --- open source --- framework --- shipyard --- industry 4.0 --- digital-twin --- gerotor pump --- hydraulic-systems --- simulation --- computer-aided design --- safety --- smart operator --- smart manufacturing --- Industry 4.0 --- digital twins (DTs) --- Internet of Things (IoT) --- sustainability requirements --- sustainable development --- product design --- n/a
