Modeling and Selection of Software Service Variants

Providers and consumers have to deal with variants, meaning alternative instances of a service?s design, implementation, deployment, or operation, when developing or delivering software services. This work presents service feature modeling to deal with associated challenges, comprising a language to represent software service variants and a set of methods for modeling and subsequent variant selection. This work?s evaluation includes a POC implementation and two real-life use cases

RETHINK!NG METABOLISM: Regenerative Architecture as an Urban Solution

This thesis will develop an architectural methodology that provides an alternative to the wasteful and restrictive approaches often used in urban development fueled predominantly by pecuniary considerations. Inspiration will be drawn from one of the last major architectural movements, Metabolism, to elicit the ideals that made “Japanese Postmodernism” unique. A specific criticism will be directed at one of the movement’s centerpieces, the Nakagin Capsule Tower, to uncover the reasons for its demise and to capture the essential values that drove the project’s design. This research will provide a strong foothold as this thesis tests the present-day validity of adaptive architecture in Memphis, Tennessee

Large-scale structural analysis: The structural analyst, the CSM Testbed and the NAS System

The Computational Structural Mechanics (CSM) activity is developing advanced structural analysis and computational methods that exploit high-performance computers. Methods are developed in the framework of the CSM testbed software system and applied to representative complex structural analysis problems from the aerospace industry. An overview of the CSM testbed methods development environment is presented and some numerical methods developed on a CRAY-2 are described. Selected application studies performed on the NAS CRAY-2 are also summarized

Towards a Digital Twin of Society

This paper describes the potential for developing a digital twin of society - a dynamic model that can be used to observe, analyze, and predict the evolution of various societal aspects. Such a digital twin can help governmental agencies and policy makers in interpreting trends, understanding challenges, and making decisions regarding investments or policies necessary to support societal development and ensure future prosperity. The paper reviews related work regarding the digital twin paradigm and its applications. The paper presents a motivating case study - an analysis of opportunities and challenges faced by the German federal employment agency, Bundesagentur für Arbeit (BA), proposes solutions using digital twins, and describes initial proofs of concept for such solutions

Progressive collapse resistance of steel-framed structures with composite floor systems

textProgressive collapse research intends to evaluate and quantify the resistance of structural systems against local failures independent of how such failures may initiate. The present research program pertains to the simulation and analysis of a structural gravity frame with composite floor system under column loss scenarios. The ultimate goal of this research is to evaluate and possibly identify any potential deficiencies in the current progressive collapse guidelines. This thesis presents the construction, testing, and results of a test performed on a steel-concrete composite structure with shear connections under a perimeter column removal. The structure was designed based on typical design guidelines. After the column removal, the specimen was subjected to increasing uniform load and was found to resist the full progressive collapse design load without major failures. In addition, computational work pertaining to the composite floor system behavior and the interaction among the beams, the slab, and the shear connectors was conducted. The purpose of this work was to identify possible deficiencies in the current simulation techniques for composite structure modeling under progressive collapse scenarios. After the analyses were conducted, it was found that the majority of current simulation techniques are adequate for modeling composite floor systems, with the use of nonlinear springs being the most accurate and computationally efficient.Civil, Architectural, and Environmental Engineerin
