International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Traditional communication hardware has focused on modular architectures. Now, with the incoming high speed DSP and FPGAs a shift from traditional modular architecture to reconfigurable architecture has taken place. The nature of this architecture allows to optimize various telemetry applications in a single platform. This paper describes a reconfigurable multi channel communication system.

Thesis (MDram)--University of Stellenbosch, 2011. / AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die verkenning, skepping en oordrag van geslagskodes in toneelpoppe. Die studie ondersoek die gebruik van geslagskodes in die skepping van manlike en vroulike identiteite. Die navorsing word baseer op Judith Butler (1999) se teorieë met betrekking tot geslagsgedrag waarvolgens geslag uit herhaalde gestyleerde aksies bestaan waaruit manlike en vroulike identiteite geskep word. Geslag word dus deur spesifieke geslagskodes weergegee wat in kleding, optrede en kommunikasie gevind word. In die studie word daar gekyk na die drie kenmerkende tekens van kommunikasie wat betrokke is by 'n toneelpop, naamlik ontwerp, beweging en spraak. Verder ondersoek die studie ook die kreatiewe prosesse soos gevind in die verhoogproduksie Cleansed (2009) wat as praktiese verkenning gedoen is om die oordrag van geslagskodes (ontwerp, beweging en spraak) by die toneelpop te illustreer. / ENGLISH ABSTRACT: This study investigates the exploration, creation and transmission of gender codes in puppetry. It investigates the gender codes used to construct masculine and feminine identities; this is done through the exploration of Judith Butler's (1999) theories on gender performativity. According to Butler (1999) gender consists of a stylized repetition of acts and through these socially constructed acts, a gendered self is constructed. Gender is thus communicated through gender codes and these codes are found in the way we dress, act and speak. This study also investigates the semiotics of the puppet, with specific reference to design, movement and speech as significant signs. This study also investigates the creative processes of Cleansed (2009). It is through this process that the gender codes (found in the design, movement and speech of the puppet) are explored, created and ultimately transmitted.

This thesis, based on a methodology borrowed from Science and Technologies Studies (STS), studies the implications of using energy modeling software for code compliance in the architectural design process. Specifically, the careful study of the development and use the of the software itself, including the assumptions and frameworks of its developers and users, is required to accurately examine the implications and practical effectiveness of using energy modeling to aid in reducing the environmental consequences of the built environment. I argue that the value in studying energy modeling software is not primarily to improve the scientific accuracy of the software. Rather, the value is to demonstrate how the assumptions used in the software’s calculation methodology can adversely influence the technological decisions made by building designers when using the software to demonstrate compliance with energy codes. To develop this hypothesis I have employed both historical and empirical methods. In my historical analysis, I find that the origins of modern building energy modeling software date back to the beginning of the air conditioning industry at the start of the 20th century. One consequence of this history is that assumptions built into the software measure the relative efficiency of building components under static and assumed average conditions, but not the dynamic rates of consumption caused by inhabitation. This, in-turn, prescribes the problem-at-hand of energy code compliance as primarily technical. However, as others have argued, dynamic social and circumstantial issues also influence energy consumption (Guy & Shove, 2000). Therefore as means to examine potential conflicts between the static and technical method of analysis employed by code compliance energy modeling software and the dynamic and circumstantial context in which buildings are designed, my empirical analysis is of a design process for a net-zero energy subdivision in Austin, Texas in which energy modeling was required and used extensively. The case study is designed to demonstrate how the problems-at-hand for each distinct group of stakeholders involved in the design process was varied and did not necessarily conform to the technical solution advocated by the energy modeling process. A primary conclusion of my analysis is that all mature technologies come to us with embedded assumptions that may subvert our intentions. A secondary conclusion is that the competing assumptions and problem definitions of building scientists and building designers tend to frustrate the goal of sustainable development. My hope in studying energy modeling, in relation to practice and code compliance, is to discover ways to better use the analytical power of energy modeling that is more directly responsive to the dynamic and contextual conditions of architectural production and real world resource consumption. / text

<p>This thesis presents new methods for finding optimal and near-optimal constant weight binary codes with distance d and weight w such that d=2(w-1). These methods have led to the discovery of a number of new codes which are being submitted for publication. Improvements in methods for generating lexicographic codes are also discussed, with suggestions for further research in this area.</p>

This study investigated the effect of four score study styles--no score study, study with score alone, study with score and a correct aural example, and score study at the electronic keyboard--on the pitch and rhythm error detection abilities of beginning conducting students. Subjects were 30 members of undergraduate beginning conducting classes at three midwestern universities. Four tests were developed, each having 31 four- to six-measure excerpts from band literature. Each excerpt contained only one error. Excerpts were grouped according to difficulty and assigned to tests in a modified random manner to facilitate equality of difficulty between sets. Within each test, excerpts were arranged in order of increasing difficulty and rescored to contain from one to eight parts. A counterbalanced design was utilized featuring a Latin Square into which the four score study styles were entered. Over the course of four sessions subjects received all four styles and all four tests. The orders in which subjects received score study styles were assigned on a rotational basis. Each subject within a university received the tests in the same order, but this order varied between universities. Six Hypercard © (Atkinson, 1987-90) stacks were developed on a Macintosh LC computer for presentation of the tests, management of the study, and data collection. Excerpts were played through MIDI keyboards using sampled wind instrument sounds. Study with the score and a correct aural example was found to be significantly more effective than either study with the score alone or no study. No significant difference was found between score study at the keyboard and any other score study style. There were significant differences in test scores attributable to the number of parts in examples. Generally, error detection became more difficult as the number of parts in examples increased. There were no significant differences in test scores attributable to the order of presentation of score study styles, individual example sets, or groups/order of presentation of example sets. There were significant differences in means score study time per session attributable to score study style, and in mean total time per session attributable to session number.

We will discuss three ways to bound the chromatic number on a Cayley graph. 1. If the connection set contains information about a smaller graph, then these two graphs are related. Using this information, we will show that Cayley graphs cannot have chromatic number three. 2. We will prove a general statement that all vertex-transitive maximal triangle-free graphs on <i>n</i> vertices with valency greater than <i>n</i>/3 are 3-colourable. Since Cayley graphs are vertex-transitive, the bound of general graphs also applies to Cayley graphs. 3. Since Cayley graphs for abelian groups arise from vector spaces, we can view the connection set as a set of points in a projective geometry. We will give a characterization of all large complete caps, from which we derive that all maximal triangle-free cubelike graphs on 2ⁿ vertices and valency greater than 2ⁿ/4 are either bipartite or 4-colourable.
