Depth of the Cube: Insight into the Analysis of a Shared Form
Full text linkThe cubic form has served as a foundation for the architectural discipline, spurring on countless projects throughout the ages. By collecting numerous examples of these projects, the developmental processes of each can be studied and compared. These processes are then organized and simplified to illustrate the various design frameworks and methodologies that the architects employed to create these designs. As these are condensed and developed into series, nearly any building that is based around the cube or similar geometric primitives can be compared to and arranged with one of the frameworks put forth by my research. Rather than having to reduce projects down to one or two aspects and measuring it up against another specific project, one can simply identify which framework a project fits into and instantly have a general understanding of the building and a way of correlating it to a host of other similar projects ono that shared framework. This entire discourse was spurred on by questioning where the basis of architectural analysis originates from and how it was developed. By creating a series of comparisons between systematically similar projects throughout various periods, the change in methods of approaching the design of a bounded shape become quite apparent. The development of representation becomes inherently tied to this idea as well since the method of design correlates to certain representational methods which h have evolved from project to project. Creating these diagrams to illustrate each design strategy is then crucial to comparing each work. Formally analyzing these projects then becomes an essential aspect of understanding the development of architectural design throughout time
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A Study to Increase Participation of Habitat for Humanity Affiliates in LEED for Homes Certification
Full text linkIn the United States, Habitat for Humanity is at the forefront of the providing affordable housing to low income homeowners. Because of this work, Habit for Humanity is one of the leading homebuilders in the United States. A recent development in the assessment of home building is an increased emphasis on the use of technology and methods that reduce the impact of housing construction and occupation on the world���s environment. Numerous methods exist to assess this impact, a major one in the United States is the LEED system developed by the US Green Building Council.
Two problems exist with the LEED system, one being cost and the time of preparation of the necessary paperwork. Other research work exists on these implementation problems for the broader community, but this study looks at the specific impact and impediments to obtaining LEED certification for Habit for Humanity housing, specifically in Texas. This study assesses Habit for Humanity affiliate���s involvement with LEED and sustainable building. This is accomplished in two parts, a survey and an analysis of LEED scorecards. To gauge the current state of sustainable building in Habitat for Humanity affiliates of Texas a survey was conducted. There were 15 participants out of 84 affiliates. The survey looked in to the current sustainable practices and barriers for the affiliates to participate in the LEED program. Then LEED score cards were obtained and analyzed, eleven scorecards total were obtained. Six scorecards were from homes built by Habitat for Humanity affiliates across the United States, and the other five scorecards came from a production home builder in Texas. The scorecards were then compared by determining the mean of points for each question.
From this case study, the survey shows cost and knowledge to be the largest barriers to LEED certification. The data from the LEED scorecards showed Water Efficiency and Indoor Environmental Quality to be the two weakest categories for the HFH affiliates compared to the production homes. These barriers can potentially be overcome by the availability of grants for sustainable building and by educating the affiliates on LEED and sustainable building. The fact that HFH is a leader in affordable housing means if HFH affiliates can build to LEED standard so can other affordable builders
Chinese Painting in 3D: An Artistic Study of the Use of the Traditional Chinese Painting Aesthetic in Three-Dimensional Computer Graphics
Full text linkThis thesis presents a study of both traditional Chinese painting and threedimensional
(3D) digital non-photorealistic shading techniques, the results of which are used
to create a short animation illustrating an environment that maintains the aesthetic of a
Chinese painting while exploring a two-dimensional art style in a new way through camera
movement and parallax.
Traditional Chinese painting uses alternative methods to communicate depth, such as
value range, water-to-ink ratio and vertical placement of objects. In contrast, perspective and
parallax are native characteristics of 3D digital technology and are easily generated using a
virtual camera. When combining these two mediums to inject linear perspective into the
Chinese painting style, it is equally important to maintain the integrity of the aesthetic by
adhering to the stylistic and compositional rules throughout the animation. As a result, the
final project may be paused at many key frames and appear to follow these rules closely.
This study also describes the methodology of translating the Chinese painting
aesthetic into a 3D digital medium, which can also be used in the interpretation of other
traditional art styles
Interactive Ray Tracing Infrastructure
Full text linkIn this thesis, I present an approach to develop interactive ray tracing infrastructures for artists. An advantage of ray-tracing is that it provides some essential global illumination (GI) effects such as reflection, refraction and shadows, which are essential for artistic applications. My approach relies on massively paralleled computing power of Graphics Processing Unit (GPU) that can help achieve interactive rendering by providing several orders of magnitude faster computation than conventional CPU-based (Central Processing Unit) rendering. GPU-based rendering makes real time manipulation possible which is also essential for artistic applications. Based on this approach, I have developed an interactive ray tracing infrastructure as a proof of concept.
Using this ray tracing infrastructure, artists can interactively manipulate shading and lighting effects through provided Graphical User Interface (GUI) with input controls. Additionally, I have developed a data communication between my ray-tracing infrastructure and commercial modeling and animation software.
This addition extended the level of interactivity beyond the infrastructure. This infrastructure can also be extended to develop 3D dynamic environments to obtain any specific art style while providing global illumination effects. It has already been used to create a 3D interactive environment that emulates a given art work with reflections and refractions
Translating Indian miniature paintings into a time-based medium
Full text linkThe purpose of this research and the corresponding project is to explore and interpret the
qualities of the traditional art form of Indian miniature paintings into a digital, time
based medium. These are beautiful, finely-drawn paintings with rich detailed patterns
and striking bold colors. Intricately and meticulously drawn, they employ an alternative
means of representation distinctly different from a conventional lens-based perspective.
Most 3-dimensional digital media makes use of either a real or a virtual camera to
inform the representation of space. In this project I deviate from this convention to create
a new visual style for animation. The project demonstrates how a consistent yet different
visual look can be achieved that retains the richness and visual expression of the
traditional painting style through the use of new technology
Bond Strength Measurements from an Australian Standard Bond Wrench in Comparison to the Unbalanced ASTM C 1072 Bond Wrench to the Balanced and Unbalanced Wrenches
Full text linkBond strength is one of the most important factors that affect the performance of the joint under various loading conditions. The flexural bond strength of a joint can be measured using a bond wrench. The first of the bond wrenches was developed in 1980s in the Australian laboratories. Former TAMU students had built a lightweight Indian unbalanced and balanced bond wrench. An Australian bond wrench was manufactured in 2011 and subsequently in 2012 an ASTM C 1072 Bond Wrench was developed.
Previous researchers have found out that no unacceptable bias existed in the flexural strength values forecasted using the Indian balanced and unbalanced wrench.The studies have also shown that there exists a bias between American Bond Wrench and Australian Bond wrenches. The Australian wrench values were significantly higher than the American bond wrenches for similar types of samples. Hence it was recommended that the tests be carried out by replacing the cement with Portland cement.
This experimental research uses Portland cement and a total of 50 prisms was built in two sets. Each prism comprised of six bricks with five joints, and all the bricks used were Texan bricks. The mortar used here was 1:1:6. The samples were cured for a period of 28 days, and all the experiments swere carried out under same weather conditions The first set prisms was tested using Australian and the American bond wrench., the second set of prims was tested using the other two wrenches.
A Student���s t-Test analysis was run between the flexural strength values of the four wrenches. From the plots, it can be inferred that the mean value of the American wrench was low when compared with the mean values of the other three wrenches. The plots of Australian bond wrench and Indian unbalanced were quite similar.
It can be concluded that the values forecasted using the American bond wrench were statistically different from the other three wrenches, and the reason can be noted as the difficulty in using the American bond wrench.
Further research is recommended using the Texas red brick
