Design review is a process of reviewing construction design documents to ensure that they reflect the owner's design intent, and are accurate in describing the owner's desired building or facility. Information generation becomes more intensive as the design stage progresses. The use of valuable information during design review stage can lead to a more comprehensive and high quality design, and a building or facility that is constructible, and within the intended budget. However, in current design practices, valuable design review information is scattered, ineffectively placed, and is not used efficiently. The design review process will be more efficient if this valuable information is integrated and centralized. The author developed a framework to improve the design review process by incorporating a centralized repository of design review information and 3D CAD model, in an interactive Virtual Environment (VE). To develop the framework, the author used Action Research style where he identified and confirmed the design review problem area, promoted the potential solutions to the problem, and developed a prototype. In gathering and analyzing the data for the research, the author used the synthesis of three methods. They include review of literature, a case study (interviews with industry personnel and content analysis of design review documents), and dissemination of the author's progressive findings in conferences, conference proceedings and journal publications. From his findings, the author developed the framework to improve the design review process by using information filtering based on context-aware concept, coupled with the benefits of a VE. The required design review information in the form of textual, numerical and geometric information is processed (queried, retrieved and stored). The author defined four contexts for information filtering: discipline-centric, task-centric, object-centric, and location-centric. IF-THEN rules are used to trigger the processing of the required design review information and present it to the design reviewer in a VE. A low cost 3D Game Engine is used as the enabling development tool to develop a work-in-progress (WIP) prototype design review application in a VE. / Ph. D.

Industry is constantly looking for ways to bring new or derivative products to market in the shortest amount of time for the least amount of money. To accomplish this, Industry has adopted Computer Aided Engineering (CAX) tools that perform structural, flow, manufacturing, and cost analysis. The way in which a company utilizes these CAX tools can determine the success of these new products. One of these tools that Industry often struggles with in the preliminary design of a product is Computational Fluid Dynamics (CFD). Some of the challenges presented by CFD are the time it takes to create a CAD model, generate a valid grid for analysis, obtain a solution, post-process results, and review the result. The objective of this thesis is to develop an approach that will reduce the time it takes to go from a concept to a solution ready for review. This approach, addresses how to first, build CAD model for use in downstream applications, second, automate the grid generation process, and third, automate the post process and documentation of the results. Using this approach a conceptual study of a two stream mixing problem was performed. The approach showed that the creation of the first model took about twenty percent longer than the standard practice used in industry today. However, once the first model was completed, different concepts could be added to the CAD model and be ready for analysis in less than half the time when compared to standard practices. This time savings can then be used to explore more concepts. After each model was analyzed, it was post-processed using an automated script. With the post-processed results the Design Review Tool (DRT) was developed to automate the documentation of the results. Using the DRT each post-processed case was organized into a web page and saved for review in less than five seconds. This approach will enable the aerospace, automotive, and other industries to use CFD to more effectively explore the design space in the development of new and derivative products. This research demonstrates the process to reduce the time required to go from CAD-to-Grid, postprocess the results, and create the documentation needed to develop new products.

I detta examensarbete görs en diskursiv och historisk undersökning av kritikgenomgången i arkitektutbildningen. Kritikgenomgången utgör en central komponent i det samtida paradigmet för arkitektutbildning – studion. Examensarbetet går igenom och diskuterar aktuell forskning om kritikgenomgången, vilket ger en nedslående bild av kritikgenomgångens pedagogiska potential. Vidare undersöks kritikgenomgångens historiska rötter med fokus på den svenska kontexten, vilket ger vid handen att kritikgenomgången i sin nuvarande form fick sin roll i svensk arkitektutbildning under 1990-talet, alltså samtidigt med studioparadigmets genomslag. Dessutom redovisas resultaten av en intervjustudie med lärare vid KTH Arkitekturskolan, vilka visar att diskursen om kritikgenomgången innehåller flera motsägelser och problem. Resultaten av undersökningarna diskuteras sedan utifrån en förståelse av omdömet som centralt begrepp och förmåga för att förstå den implicita definition av arkitekten som manifesteras i kritikgenomgången och i disciplinens kanon. / This thesis presents a discursive and historical investigation of the origins and causes of the design review in architectural education. The design review, jury or ”crit” i s an integral and central part of the contemporary paradigm for architectural education – the design studio. The thesis discusses previous research on the design review, which paints a gloomy picture of the learning possibilities of the review. The historical roots of the review are studied with the Swedish context as a focus, showing that the review in its contemporary form was adopted concurrently with the design studio paradigm during the 1990’s. Furthermore, interviews were carried out with instructors at the School of Architecture at the Royal Institute of Technology in Stockholm. Results from the interviews point to several contradictions and issues in the discourse about the review. Seeing the concept and faculty of judgment as central to understand the implicit definition of the architect, as manifested in the review and in the canon of the discipline, these findings are the discussed and contextualised.

abstract: Emerging information and communication technology (ICT) has had an enormous effect on the building architecture, engineering, construction and operation (AECO) fields in recent decades. The effects have resonated in several disciplines, such as project information flow, design representation and communication, and Building Information Modeling (BIM) approaches. However, these effects can potentially impact communication and coordination of the virtual design contents in both design and construction phases. Therefore, and with the great potential for emerging technologies in construction projects, it is essential to understand how these technologies influence virtual design information within the organizations as well as individuals’ behaviors. This research focusses on understanding current emerging technologies and its impacts on projects virtual design information and communication among projects stakeholders within the AECO organizations. / Dissertation/Thesis / Doctoral Dissertation Civil and Environmental Engineering 2017

Master of Regional and Community Planning / Department of Landscape Architecture/Regional and Community Planning / Larry L. Lawhon / Gated communities are a growing residential phenomenon in the United States with almost ten percent of households living in gated communities in 2005 (Knox, 2008; Census, 2005). In this study “gated communities” are defined, according to Low (2003), as a residential neighborhood with walls and gates surrounding the development, which excludes non-residents access to all interior amenities including residences, open space, and activities. People are seeking life behind a gate for many reasons, but include the search for security, safety, privacy, prestige, exclusivity, control, and community (Blakely & Snyder, 1999). As this style of development is expanding and as all socio-economic groups want to live in gated communities, cities are beginning to realize gated communities affect all members of the community, not just the ones secluded behind the gate (El Nasser, 2002). After reviewing literature, the author found, the generally accepted social implications and consequences resulting from gated communities were identified as social segregation, loss of community, and division; although, there were also positive results for some people living within gated communities. This report, through a case study format, investigated if the social implications of gated communities are considered during the development review process. Rockwood Falls Estates and Meadows is a suburban gated community and the surrounding local governments, Johnson County and Overland Park, were the object of the case study. The author concluded that gated communities have benefits and concerns. Further, the author found that gated communities can be effectively controlled if the local governments have adopted specific policies dealing with gated communities and implement this policy through specific design review procedures.

The Vieux Carré in New Orleans is the second oldest locally designated historic district and serves as a prominent example of local historic preservation efforts; however, the Vieux Carré has a high vacancy rate. This thesis examines the effects of land use policy, including the Comprehensive Zoning Ordinance and the design review process in the Vieux Carré, on attempts to return vacant buildings to commerce. The author examines three cases of redevelopment attempts of vacant properties in the Vieux Carré. In two of the three cases, constrictions from the Zoning Ordinance not the design review process held up the redevelopment process. The other case identified owner negligence as the cause for failure in the redevelopment attempt.

Deficiencies in software design or architecture can severely impede and slow down the software development and maintenance progress. Bad smells and anti-patterns can be an indicator for poor software design and suggest for refactoring the affected source code fragment. In recent years, multiple techniques and tools have been proposed to assist software engineers in identifying smells and guiding them through corresponding refactoring steps. However, these detection tools only cover a modest amount of smells so far and also tend to produce false positives which represent conscious constructs with symptoms similar or identical to actual bad smells (e.g., design patterns). These and other issues in the detection process demand for a code or design review in order to identify (missed) design smells and/or re-assess detected smell candidates. UML diagrams are the quasi-standard for documenting software design and are often available in software projects. In this position paper, we investigate whether (and to what extent) UML diagrams can be used for identifying and assessing design smells. Based on a description of difficulties in the smell detection process, we discuss the importance of design reviews. We then investigate to what extent design documentation in terms of UML2 diagrams allows for representing and identifying software design smells. In particular, 14 kinds of design smells and their representability in UML class and sequence diagrams are analyzed. In addition, we discuss further challenges for UML-based identification and assessment of bad smells.

Vorbeugende QM-Techniken operationalisieren die Funktionen des Qualitätsmanagements (QM) mit dem Ziel einer abgesicherten Produktentstehung. Sie leisten einen wesentlichen Beitrag zur Erhöhung der Produktqualität. Jedoch zeigen Untersuchungen, dass deren Einsatz häufig sehr große Probleme bereitet. Die vorliegende Arbeit untersucht vordergründig die FMEA, QFD und DRBFM. Neben der Beschreibung ihrer Anwendungsbereiche, werden die Vorteile und Schwächen gegenübergestellt. Es gilt, die Schwächen mit Hilfe einer neu entwickelten Methode zu umgehen bzw. zu eliminieren. Die Entwicklung zentraler Schwerpunkte zur Erreichung von Null-Fehlerqualität liefert die Basis für die Erstellung einer Checkliste in Form eines Fragenkataloges. Ziel soll es sein, durch die Systematik des Fragenkataloges und Wahl des Antwortformates Fehlerursachen zu vermeiden.

Le développement d'un environnement collaboratif est un processus complexe. La complexité réside dans le fait que ce développement implique beaucoup de prise de décisions. De multiples compromis doivent être faits pour répondre aux exigences actuelles et futures d'utilisateurs aux profils variés. La prise en compte de cette complexité pose des problèmes aux chercheurs, développeurs et utilisateurs. Les informations et données requises pour prendre des décisions adéquates de conception et évaluer rigoureusement ces décisions sont nombreuses, parfois indéterminées et en constante évolution. Dans la partie-I de cette thèse, nous formulons les connaissances générales sur le travail collaboratif synchrone qui constituent l'état de l'art du domaine du problème. Nous pratiquons de même pour les environnements collaboratifs synchrones (domaine de la solution technique) et leur cette formulation s'appuie sur une étude de la littérature et conduit à la proposition de Schéma Conceptuel (Concept Maps). Nous en déduisons trois modèles: SyCoW (travail collaboratif synchrone), SyCoE (environnement collaboratif synchrone) et SyCoEE (évaluation environnement collaboratif synchrone). Dans la partie II de cette thèse, nous proposons un processus pour la sélection / développement d'un environnement collaboratif, où nous démontrons comment les modèles SyCoW, SyCoE et SyCoEE structurent ce processus. Grâce à la mise en œuvre de la démarche proposée, nous présentons le développement d'un nouvel environnement collaboratif synchrone pour une réunion de revue de conception nommé MT-DT. MT-DT a été conçu, développé et évalué par l'auteur dans sa thèse de doctorat. MT-DT est une application logicielle 3D spécifique à une table multi-touche qui assiste les activités de revue de conception collaborative. Les résultats de l'évaluation ont confirmé la convivialité de MT-DT et fournissent des éléments de validation des choix que nous avons faits au cours du développement de MT-DT. / Development of collaborative environment is a complex process. The complexity lies in the fact that collaborative environment development involves a lot of decision making. Several tradeoffs need to be made to satisfy current and future requirements from a potentially various set of user profiles. The handling of these complexities poses challenges for researcher, developers and companies. The knowledge required to make suitable design decisions and to rigorously evaluate those design decisions is usually broad, complex, and evolving. In Part-I of this thesis we investigate to formulate the general knowledge about: synchronous collaborative work which conceptualize the problem domain, synchronous collaborative environment which conceptualize the solution domain and synchronous collaborative environment evaluation which conceptualize the evaluation of whole or part of the proposed solution for the specified problem. This formulation has been done through literature study and leaded to the Concept Maps. The results generate three models: SyCoW (synchronous collaborative work), SyCoE (synchronous collaborative environment) and SyCoEE (synchronous collaborative environment evaluation). In Part-II of this thesis we proposed a process for selection/development of collaborative environment, where we demonstrate how SyCoW, SyCoE and SyCoEE support this process in different ways. Through the proposed process we present the development of new synchronous collaborative environment for design review meeting, named, MT-DT. MT-DT has been designed, developed and evaluated by the author in her PhD. MT-DT consist of a multi-touch table with specific 3D software application which support collaborative design review activities. The results of evaluation confirmed the usability of MT-DT and provide arguments for our choices which we made during development of MT-DT.
