Informing Sustainable Standards in 'The Circular Economy' utilising technological and data solutions
In our world of make, use and throw away we are now doing more damage to the planet than good, and this mindset has become unsustainable. One of the solutions to this problem is the ‘Circular Economy’ (CE). The CE replaces the concept of end-of-life production with restoration of natural systems, innovative design to design out waste and keeping products and materials in circulation for as long as possible.
This research will use data science and statistical information to provide a solid foundation (framework) for standards developers to frame the development of standards for the CE. The research will extend the current CE model by interjecting innovative ideas into areas of the CE process: data analysis, restriction of harmful chemicals removing them from the supply chain, research into Local Value Creation (LVC) and research into Sustainable Development in the CE. The research will investigate how Radio Frequency Identification (RFID) tagging of products and materials provide a realistic way to trace products and materials in a CE management system. It will also expand the knowledge on digitization in standards development by analyzing key data streams connected to the CE in order to inform the standards development community of the need to develop a standard on the CE.
This research will use a mixed methodology by combining quantitative methods (data analysis) and qualitative data (case studies). This will be detailed in Chapter 3 – Methodology. The data collected from the literature review will drive four main Sections and four research questions in Chapter 4.
This research will analyse through Case Studies and research papers the uptake of circular thinking in China and the Ellen MacArthur Foundation and use the outcomes positive or negative to show practical applications for this research.The objective conclusion of this research is to provide a framework for a European or International standard in order to fill the gap as no such Standard currently exists European or Internationally that addresses the CE.
A Framework with inclusions from the research will form a usable output from the research. This research will inform or be of interest to the Standards development community, data scientists, Circular Economy practitioners and environmental regulators.
The aim of this research is to provide a framework standard using underlying data and statistical information needed to develop a new Standard on the Circular Economy.
Once a Standard is developed and published it can be used by any organisation or group of organisations, country or individual wishing to manage internally and collectively their activities in order to transition to the CE and the Sustainable Development goal of responsible consumption and production.
This research has produced a framework from which sustainable standards can be developed. The data acquired from using RFID tags imbedded in products allows manufacturers to control and analyse the materials in their products specific to hazardous chemicals. This data can also be used to track the product through the supply chain and onto its product life cycle. The data gathered in the product example in this thesis tracks the potential use of hazardous chemicals in the product, this is important information for endof-life decisions to be made on the product. The data can then be used to develop requirements and testing regimes for circular economy standards.
Having identified some of the main areas of future activity in the CE, this research i.e., the circular economy, data science and standards development will continue to evoke research in the CE for the foreseeable future
Study of the benefits and applications of passenger supersonic transport vehicles: case study of Starship-SpaceX
The demand that exists in commercial aviation is increasing more and more frequently, allowing the new space technologies that are being developed to come into play to tackle this problem, which could have a major impact on mobility in the next few years. However, before these new technologies enter the market, they need to be studied and monitored in order to assess their benefits and possible applications in this sector. Nowadays, there are already a large number of active projects that seek to make high-speed passenger air transport a reality, as was already the case with the Concorde at the time but trying to tackle the major drawbacks that this model had, with the application of the innovative technologies that are currently being developed. This study focuses on SpaceX’s project Starship, which through a Case Study, has subsequently integrated all the information obtained in a CANVAS market study; in addition to carrying out an environmental study and an analysis of risks. In addition, it has been possible to identify the key points that intensify the value proposition of the model, but also the weaknesses or shortcomings that could have a negative impact on the outcome of the project. By assessing all these factors, it has been possible to conclude that by using the appropriate measurement tools to control these drawbacks, the company has a proposal with a bright future that is supported by the great potential that SpaceX has thanks to its business lines, its allies/stakeholders and its long experience in the space sector. When new space technologies flourish successfully, this model could become the most powerful in the world

Quality of explosively welded steel plates using demex explosive
Заваривање експлозивом се често користи када конвенционалне методе заваривања не
могу да обезбеде заварени спој два различита материјала, али и када треба заварити неку
специфичну геометрију или велике површине металних плоча. Остваривање споја код
заваривања експлозивом се заснива на динамичком дејству великог притиска створеног
екплозијом. У ту сврху најчешће се користе индустријски експлозиви ниских параметара
детонације, а један од њих је DEMEX, произвођача TRAYAL, из Србије. У овом истраживању
DEMEX је примењен за заваривање плоча две различите врсте челика. Пре
експерименталног поступка заваривања одабраних металних плоча, експлозив добијен од
произвођача је подвргнут улазној контроли квалитета: мерењу његове насипне густине и
брзине детонације, коришћењем оптичких сонди и фотодетектора повезаног са
електронским бројачем. Експериментална поставка за заваривање била је следећа:
експлозив DEMEX у прашкастом стању нанесен је у равномерном слоју преко горње челичне
плоче, која је хоризонтално постављена преко доње плоче од друге врсте челика, у
паралелном положају, са малим дрвеним дистанцерима ивично постављеним између њих.
Активација је извршена електродетонирајућом капислом и малим бустером од пластичног
експлозива. Заварени спој је испитан применом метода ултразвучне дефектоскопије,
течним пенетрантима и микроструктурне анализе завареног споја. Микроструктурне
анализе попречног пресека заварених плоча урађене су на стерео и оптичом микроскопу како
би се анализирала зона завареног споја.Explosion welding is often used when conventional welding methods cannot provide welded
joint of two dissimilar materials, but also when some specific geometry should be welded, or large
surfaces of metal plates. The formation of a joint in explosive welding is based on the dynamic effect
of the high pressure created by the explosion. For this purpose, most often some industrial explosives
of low detonation parameters are used, and one of them is DEMEX, produced by TRAYAL,
Serbia. In this research DEMEX was applied to weld plates of two different types of steel. Prior to
the experimental procedure of welding, the selected metal plates, the explosive obtained from the
producer was subjected to initial quality control: measurement of its bulk density and detonation
velocity, using optical probes and a photodetector connected with an electronic counter. The experimental
setup for welding was as follows: explosive DEMEX in powdery state was applied in a uniform
layer over the upper plate, which was horizontally placed over the lower plate, in parallel
position, with small wooden spacers, marginally placed between them. Activation was performed by
an electro-detonating cap and a small booster of plastic explosive. The welded joint was examined
using methods of ultrasonic defectoscopy, liquid penetrants testing and microstructural analysis of
the welded joint. Cross-sectional microstructural analyses of the welded plates were performed
using a stereo and optical microscope to analyze the weld zone

THE BOMBER WILL ALWAYS GET THROUGH: THE ORIGIN OF THE B-21 STEALTH BOMBER
The aim of this dissertation is to explain why and how the United States decided to build the B-21 stealth bomber. The B-21 Raider is the most recent endeavor to find a worthy successor (though not, strictly speaking, a replacement) for the B-52 Stratofortress. The B-21’s immediate predecessor, the B-2 Spirit, was conceived over forty years ago with the same purpose in mind. Understanding why and how the B-2 came to life, and how and why it fell far short of its intended production goal, offers insights into its successor, the B-21. By conducting a comparative analysis of the B-2 and the B-21 via the four dominant forces found in the defense acquisition literature--bureaucratic politics, technology, politics, and strategic need--it was found that neither program could begin until all of the forces were in alignment. And in the case of the B-2, it was discovered that when those forces fell out of alignment, the program was subsequently terminated. While it cannot be known how successful the B-21 program will be, thus far, the program has exhibited signs of institutional learning from the B-2 program’s early demise, which portends it will not suffer the same fate. Given the historical contribution of this study and its associated findings, this research will be of particular interest to defense acquisition professionals, military elites, Congress, scholars, and students of history, among others.Lieutenant Colonel, United States Air ForceApproved for public release.
