This thesis deals with sustainability assessment for application in conceptual aircraft design. An assessment methodology is developed and integrated into an existing conceptual aircraft design environment. The key characteristics compared to the current state of the art is the consistent and quantitative assessment approach for the entire aircraft life cycle and the consideration of sustainability including economic, environmental, and social aspects. The developed methodology is based on the theoretical concept of life cycle sustainability assessment (LCSA) comprising eco-efficiency analysis (EEA) and social assessment. Due to the different maturity and complexity levels of methods for EEA and social assessment, a successive process for LCSA is established in this thesis leading to the development of two methodologies: a streamlined eco-efficiency analysis (s-EEA) methodology for assessment of the complete aircraft life cycle towards selected economic and environmental impact categories, and a streamlined sustainability assessment (s-LCSA) methodology. The latter focuses on the eco-efficiency hot spot of the aircraft life cycle as determined by the s-EEA methodology and includes an indicator set with corresponding quantification methods for assessment of all three sustainability dimensions. Quantification methods are developed, with which the corresponding impacts can be determined in conceptual aircraft design. All methods are integrated into the conceptual aircraft design environment MICADO for sustainability assessment within the design loop. With this integrated assessment framework two comprehensive case studies are performed that outline the potential to improve overall sustainability by operational modifications, retrofit, as well as aircraft redesign.

Chaucer's mastery of language in the 14th century is highlighted through his diverse vocabulary, which includes intellectual, technical, and colloquial terms. His playful shifts between formal and informal speech, along with the use of various dialects, vividly portray the speech patterns of his contemporaries. The paper explores how Chaucer's keen sociolinguistic observations enabled him to capture and convey the richness of English vernacular, particularly in The Canterbury Tales, providing a valuable insight into the linguistic heritage he passed down.

The narrative centers on Vyry, a black female slave who yearns for freedom, reflecting her journey towards liberation post-Civil War. Alongside Vyry's personal story, the novel intricately weaves historical context and political developments of the era, showcasing complex characters, including white perspectives. The detailed portrayal of slave life, family dynamics, and cultural hierarchies enriches the narrative. The examination of these elements positions the work as a folk novel, emphasizing the oral traditions of African American heritage that Walker aims to preserve.
