Analysis and Selection of a Remote Docking Simulation Visual Display System
The development of a remote docking simulation visual display system is examined. Video system and operator performance are discussed as well as operator command and control requirements and a design analysis of the reconfigurable work station
UEFI BIOS Accessibility for the Visually Impaired
People with some kind of disability face a high level of difficulty for
everyday tasks because, in many cases, accessibility was not considered
necessary when the task or process was designed. An example of this scenario is
a computer's BIOS configuration screens, which do not consider the specific
needs, such as screen readers, of visually impaired people. This paper proposes
the idea that it is possible to make the pre-operating system environment
accessible to visually impaired people. We report our work-in-progress in
creating a screen reader prototype, accessing audio cards compatible with the
High Definition Audio specification in systems running UEFI compliant firmware.Comment: 6 page
Research in nonlinear structural and solid mechanics
Recent and projected advances in applied mechanics, numerical analysis, computer hardware and engineering software, and their impact on modeling and solution techniques in nonlinear structural and solid mechanics are discussed. The fields covered are rapidly changing and are strongly impacted by current and projected advances in computer hardware. To foster effective development of the technology perceptions on computing systems and nonlinear analysis software systems are presented
Ada training evaluation and recommendations from the Gamma Ray Observatory Ada Development Team
The Ada training experiences of the Gamma Ray Observatory Ada development team are related, and recommendations are made concerning future Ada training for software developers. Training methods are evaluated, deficiencies in the training program are noted, and a recommended approach, including course outline, time allocation, and reference materials, is offered
Revisión tecnológica del aprendizaje de idiomas asistido por ordenador: una perspectiva cronológica
El presente artÃculo aborda la evolución y el
avance de las tecnologÃas del aprendizaje de
lenguas asistido por ordenador (CALL por sus
siglas en inglés, que corresponden a Computer-
Assisted Language Learning) desde una perspectiva
histórica. Esta revisión de la literatura sobre
tecnologÃas del aprendizaje de lenguas asistido
por ordenador comienza con la definición del
concepto de CALL y otros términos relacionados,
entre los que podemos destacar CAI, CAL,
CALI, CALICO, CALT, CAT, CBT, CMC o
CMI, para posteriormente analizar las primeras
iniciativas de implementación del aprendizaje
de lenguas asistido por ordenador en las décadas
de 1950 y 1960, avanzando posteriormente a
las décadas de las computadoras centrales y las
microcomputadoras. En última instancia, se
revisan las tecnologÃas emergentes en el siglo XXI,
especialmente tras la irrupción de Internet, donde
se presentan el impacto del e-learning, b-learning,
las tecnologÃas de la Web 2.0, las redes sociales
e incluso el aprendizaje de lenguas asistido por
robots.The main focus of this paper is on the advancement
of technologies in Computer-Assisted Language
Learning (CALL) from a historical perspective.
The review starts by defining CALL and its related
terminology, highlighting the first CALL attempts
in 1950s and 1960s, and then moving to other
decades of mainframes and microcomputers.
At the final step, emerging technologies in 21st
century will be reviewed

Visualizing Magnitude and Direction in Flow Fields
In weather visualizations, it is common to see vector data represented by glyphs placed on grids. The glyphs either do not encode magnitude in readable steps, or have designs that interfere with the data. The grids form strong but irrelevant patterns. Directional, quantitative glyphs bent along streamlines are more effective for visualizing flow patterns.
With the goal of improving the perception of flow patterns in weather forecasts, we designed and evaluated two variations on a glyph commonly used to encode wind speed and direction in weather visualizations. We tested the ability of subjects to determine wind direction and speed: the results show the new designs are superior to the traditional. In a second study we designed and evaluated new methods for representing modeled wave data using similar streamline-based designs. We asked subjects to rate the marine weather visualizations: the results revealed a preference for some of the new designs
Seeing the smart city on Twitter: Colour and the affective territories of becoming smart
This paper pays attention to the immense and febrile field of digital image files which picture the smart city as they circulate on the social media platform Twitter. The paper considers tweeted images as an affective field in which flow and colour are especially generative. This luminescent field is territorialised into different, emergent forms of becoming ‘smart’. The paper identifies these territorialisations in two ways: firstly, by using the data visualisation software ImagePlot to create a visualisation of 9030 tweeted images related to smart cities; and secondly, by responding to the affective pushes of the image files thus visualised. It identifies two colours and three ways of affectively becoming smart: participating in smart, learning about smart, and anticipating smart, which are enacted with different distributions of mostly orange and blue images. The paper thus argues that debates about the power relations embedded in the smart city should consider the particular affective enactment of being smart that happens via social media. More generally, the paper concludes that geographers must pay more attention to the diverse and productive vitalities of social media platforms in urban life and that this will require experiment with methods that are responsive to specific digital qualities
