Evaluation of the Hybrid-Electric Aircraft Project Airbus E-Fan X

Benegas Jayme, Diego January 2019 (has links) (PDF)
Purpose - This master thesis evaluates the hybrid-electric aircraft project E-Fan X with respect to its economical and environmental performance in comparison to its reference aircraft, the BAe 146-100. The E-Fan X is replacing one of the four jet engines of the reference aircraft by an electric motor and a fan. A turboshaft engine in the cargo compartment drives a generator to power the electric motor. --- Methodology - The evaluation of this project is based on standard aircraft design equations. Economics are based on Direct Operating Costs (DOC), which are calculated with the method of the Association of European Airlines (AEA) from 1989, inflated to 2019 values. Environmental impact is assessed based on local air quality (NOx, Ozone and Particulate Matter), climate impact (CO2, NOx, Aircraft-Induced Cloudiness known as AIC) and noise pollution estimated with fundamental acoustic equations. --- Findings - The battery on board the E-Fan X it is not necessary. In order to improve the proposed design, the battery was eliminated. Nevertheless, due to additional parts required in the new configuration, the aircraft is 902 kg heavier. The turboshaft engine saves only 59 kg of fuel. The additional mass has to be compensated by a payload reduced by 9 passengers. The DOC per seat-mile are up by more than 10% and equivalent CO2 per seat-mile are more than 16% up in the new aircraft. --- Research limitations - Results are limited in accuracy by the underlying standard aircraft design calculations. The results are also limited in accuracy by the lack of knowledge of some data of the project. --- Practical implications - The report contributes arguments to the discussion about electric flight. --- Social implications - Results show that unconditional praise given to the environmental characteristics of this industry project are not justified.

Auditable Computations on (Un)Encrypted Graph-Structured Data

Servio Ernesto Palacios Interiano (8635641) 29 July 2020 (has links)
<div>Graph-structured data is pervasive. Modeling large-scale network-structured datasets require graph processing and management systems such as graph databases. Further, the analysis of graph-structured data often necessitates bulk downloads/uploads from/to the cloud or edge nodes. Unfortunately, experience has shown that malicious actors can compromise the confidentiality of highly-sensitive data stored in the cloud or shared nodes, even in an encrypted form. For particular use cases —multi-modal knowledge graphs, electronic health records, finance— network-structured datasets can be highly sensitive and require auditability, authentication, integrity protection, and privacy-preserving computation in a controlled and trusted environment, i.e., the traditional cloud computation is not suitable for these use cases. Similarly, many modern applications utilize a "shared, replicated database" approach to provide accountability and traceability. Those applications often suffer from significant privacy issues because every node in the network can access a copy of relevant contract code and data to guarantee the integrity of transactions and reach consensus, even in the presence of malicious actors.</div><div><br></div><div>This dissertation proposes breaking from the traditional cloud computation model, and instead ship certified pre-approved trusted code closer to the data to protect graph-structured data confidentiality. Further, our technique runs in a controlled environment in a trusted data owner node and provides proof of correct code execution. This computation can be audited in the future and provides the building block to automate a variety of real use cases that require preserving data ownership. This project utilizes trusted execution environments (TEEs) but does not rely solely on TEE's architecture to provide privacy for data and code. We thoughtfully examine the drawbacks of using trusted execution environments in cloud environments. Similarly, we analyze the privacy challenges exposed by the use of blockchain technologies to provide accountability and traceability.</div><div><br></div><div>First, we propose AGAPECert, an Auditable, Generalized, Automated, Privacy-Enabling, Certification framework capable of performing auditable computation on private graph-structured data and reporting real-time aggregate certification status without disclosing underlying private graph-structured data. AGAPECert utilizes a novel mix of trusted execution environments, blockchain technologies, and a real-time graph-based API standard to provide automated, oblivious, and auditable certification. This dissertation includes the invention of two core concepts that provide accountability, data provenance, and automation for the certification process: Oblivious Smart Contracts and Private Automated Certifications. Second, we contribute an auditable and integrity-preserving graph processing model called AuditGraph.io. AuditGraph.io utilizes a unique block-based layout and a multi-modal knowledge graph, potentially improving access locality, encryption, and integrity of highly-sensitive graph-structured data. Third, we contribute a unique data store and compute engine that facilitates the analysis and presentation of graph-structured data, i.e., TruenoDB. TruenoDB offers better throughput than the state-of-the-art. Finally, this dissertation proposes integrity-preserving streaming frameworks at the edge of the network with a personalized graph-based object lookup.</div>

Governing Social Innovation in Rural Areas: The Role of Member Based Organisations

Martens, Katrin 08 August 2022 (has links)
Ausgehend von der Feststellung, dass einerseits Innovationsprozesse in ländlichen Räumen wenig erforscht sind und andererseits das Wissen um die Innovationsfähigkeit ländlicher Akteure dringend erforderlich ist, um eine nachhaltige Transformation zu erreichen, beschäftigt sich diese Dissertation mit der Frage, wie soziale Innovationsprozesse in ländlichen Räumen funktionieren und gefördert werden können. Es wurden drei Studien erstellt, die sich der Beantwortung dieser Frage aus unterschiedlichen Perspektiven nähern. Beginnend mit dem Thema der nachhaltigen Zertifizierung von Ölpalmen-Kleinbauern in Indonesien, der Frage der Erhaltung und Schaffung ländlicher Infrastruktur in Deutschland und dem Thema der Energiewende und ihrer Förderung. Im Mittelpunkt aller Studien steht die Untersuchung kollektiven Handelns von mitgliederbasierten Organisationen, die als Sozialunternehmen im ländlichen Raum gegründet und betrieben werden. Zusammenfassend lässt sich feststellen, dass die Rolle von mitgliedschaftsbasierten Organisationen in ländlichen Gebieten die Untersuchung von sozialen Innovationsprozessen ermöglicht. Es konnten wichtige Merkmale und Prozesse sozialer Innovationsprozesse identifiziert werden, die nicht nur für die Förderung von mitgliederbasierten Organisationen, sondern auch für die Untersuchung nachhaltiger Transformationspfade vielversprechend sind. Die Dissertation schließt mit einer kritischen Diskussion über die Grenzen der Doktorarbeit, dem Bezug zu aktuellen wissenschaftlichen Debatten, einigen Governance Empfehlungen und einer Positionierung der Forscherin in ihrem Forschungsfeld. / Based on the observation that, on the one hand, innovation processes in rural areas have been little researched and, on the other hand, knowledge about the capacity for change of rural actors urgently needs to be taken into account to achieve sustainable transformation, this dissertation deals with the question of how social innovation processes in rural areas function and can be promoted. Three studies were conducted that approach the answer to this question from different perspectives. Starting with the issue of sustainable certification of oil palm smallholders in Indonesia, the issue of maintaining and establishing rural infrastructure in Germany, and the topic of the renewable energy transition and its promotion. At the heart of all studies is an examination of collective action by membership-based organizations established and operated as social enterprises in rural areas. In conclusion, the role of membership-based organisations in rural areas enables the study of social innovation processes. Important characteristics and processes of social innovation governance could be identified, which are promising not only for promoting membership-based organisations but also for studying sustainable transformation pathways. The thesis concludes with a critical discussion about the limitations of the doctoral thesis, the reference to current scientific debates, some governance recommendations, and the researcher's positioning in his research field.

Streamlining Certification Management with Automation and Certification Retrieval : System development using ABP Framework, Angular, and MongoDB / Effektivisering av certifikathantering med automatisering och certifikathämtning : Systemutveckling med ABP Framework, Angular och MongoDB

Hassan, Nour Al Dine January 2024 (has links)
This thesis examines the certification management challenge faced by Integrity360. The decentralized approach, characterized by manual processes and disparate data sources, leads to inefficient tracking of certification status and study progress. The main objective of this project was to construct a system that automates data retrieval, ensures a complete audit, and increases security and privacy.  Leveraging the ASP.NET Boilerplate (ABP) framework, Angular, and MongoDB, an efficient and scalable system was designed, developed, and built based on DDD (domain-driven design) principles for a modular and maintainable architecture. The implemented system automates data retrieval from the Credly API, tracks exam information, manages exam vouchers, and implements a credible authentication system with role-based access control.  With the time limitations behind the full-scale implementation of all the planned features, such as a dashboard with aggregated charts and automatic report generation, the platform significantly increases the efficiency and precision of employee certification management. Future work will include these advanced functionalities and integrations with external platforms to improve the system and increase its impact on operations in Integrity360.

Curriculum development for the master craftsman in the printing, newspaper and packaging industries

Thomas, David Llewellyn, 1944- 01 1900 (has links)
This study centres on curriculum development for a master craftsman level in the Printing, Newspaper and Packaging Industries which is didactically sound and takes cognisance of the dynamic vocational education and training milieu in which it occurs. Curriculum and curriculum development is viewed from a systems perspective and incorporates the specific andragogic didactic needs of the learner target group as well as the unique needs of an industrial sector. Because the National Qualification Framework model advocates an outcomes-based approach to curriculum development this necessitated the identification of a suitable standards generating process to articulate the master craftsman unit standards into a qualification capable of being recognised by the National Qualification Framework. The nature and complexity of the underpinning knowledge, skills and competencies for the master craftsman level were quantified and qualified by means of skills and competency profiling and the development of a job outcome taxonomy of skills, knowledge and attributes which incorporated critical cross field and fundamental skills, and their underpinning knowledge requirements. Using aspects ofvarious vocational education and training models and empirical research course content was sourced, evaluated and developed into appropriate modules of learning that are congruent with the accepted competency based modular training system used in the Industries. Course maps that integrate theory and practice were developed with multi skilling milestones linked to learner certification. Evaluation of resources for the delivery of the Master Craftsman Programme was facilitated by means of a provider quality assessment and accreditation system. The interactive teaching-learning situation and the evaluation processes and procedures were developed to enhance the assessment of applied competencies in the world of work. A pilot study and unit standards generating activities are to be used as a means of implementing and institutionalising the master craftsman curriculum. The findings of this study revealed that by viewing the curriculum from a systems perspective and using a suitable curriculum development model a creative master craftsman curriculum development process could take place. The competency profiling technique and taxonomy of competencies, skills, knowledge and attributes enabled the curriculum process to be a top-down approach which is outcomes-based. / Didactics / D.Ed.

Indicadores empresariais de qualidade de vida no trabalho: esforço empresarial e satisfação dos empregados no ambiente de manufaturas com certificação ISO 9000 / Business indicators of life quality at work: companys effort and employees satisfaction at ISO 9000 certified manufacturers environment.

Franca, Ana Cristina Limongi 20 December 1996 (has links)
Este trabalho examina Qualidade de Vida no Trabalho nas manufaturas, de médio porte que obtiveram certificação ISO 9000. Nosso principal objetivo foi investigar as prováveis relações entre esforço da empresa e satisfação dos empregados através de indicadores empresariais selecionados com critérios da abordagem biopsicossocial. O método de pesquisa foi estudo de campo, com o modelo de variáveis dependentes e independentes. Os dados foram coletados em 26 empresas e 446 questionários, na Região de São Paulo. Os resultados demonstram inicialmente comparações através de análise exploratória entre gerência de recursos humanos e empregados. A seguir, levantaram-se fatores de satisfação dos empregados, quais sejam: atuação organizacional, necessidades biológicas, inclusão social, prestação de serviços; e fatores de esforço das empresas: imagem, desenvolvimento profissional, administração de recursos humanos, saúde e ética, demandas legais e reposição de energias. Através de análise de conglomerados foram obtidos perfis de atitudes dos empregados. Os perfis são diferenciados entre realização, desconfiança ou crítica à empresa. Finalmente, obtivemos resultados sobre tipos de gestão. Os tipos identificados foram estruturado, reativo e aleatório. Relacionando-se esses tipos de gestão e perfis dos empregados, constatou-se que a satisfação dos empregados localiza-se mais na imagem da empresa e em programas de atendimento a saúde e benefícios, que no tipo de gestão. / This work deals with Life Quality at Work at medium-sized manufacturers that had been awarded ISO 9000 certificate. We targeted investigating the potential relationship between companys effort and employees satisfaction through the selected companys indicators based on criteria of the bio-psycho-social approach. Research method was the field study with the model of dependent and independent variables. Data were collected at 26 companies by 446 questionnaires in the São Paulo Region. Results show first comparisons through exploratory analysis of human resources management and employees. Following, employees satisfaction factors were identified as follows: organizational acting, biological needs, social integration, service rendering; so were the companys effort factors: image, professional development, human resources management, health and ethics, legal actions and energy recovery. By means of a cluster analysis, the employees attitude profile was obtained. They were made distinct among accomplishment, discredit or criticism about the company. Finally, we have obtained results related to kinds of management. Identified kinds were structured, reactive and random. After relating these kinds of management and employees profiles, we could find out that employees satisfaction is based more on the companys image and on medical services and benefits than on the kind of management.

Managing student dropout rates at a technical vocational education and training college in KwaZulu-Natal

Mdluli, Koko Jumaima 07 May 2018 (has links)
The aim of the study was to investigate ways in which student dropout rates could be managed at a Technical Vocational Education and Training College (TVET) in KwaZulu-Natal, Amajuba District. Twenty-eight participants were purposively selected from two campuses in the area representing the Business and Engineering studies. This was done using the non-probability purposive sampling. The researcher focused on determining ways to assist in improving the management of student dropout rates in the above TVET College so as to increase the throughput and the certification rates. The study employed a qualitative design with semi-structured interviews that were conducted with senior managers from the central office, Heads of Departments, lecturers and students who had previously dropped out from the college so as to examine their views and perceptions on the effects of student dropout rates and how the management of student dropout rates could be improved. Data were analysed thematically whereby information was categorised into themes that emerged from the responses of the participants. The findings revealed that causes of student dropout emanate from the financial challenges experienced by students in this area since most of them are from disadvantaged backgrounds, institutional factors such as poor or lack of career guidance, the curriculum, poor enrolment procedure and poor student support services. The study recommends that well organised and effective career guidance should be conducted, the curriculum should be reviewed, and the selection and enrolment procedures should be transparent and understood by everyone. Recommendations for further study are also provided. / Educational Leadership and Management / M. Ed. (Education Management)
