Three dimensional visualization of the World Wide Web

Although large-scale public hypermedia structures such as the World Wide Web are popularly referred to as "cyberspace", the extent to which they constitute a space in the everyday sense of the word is questionable. This paper reviews recent work in the area of three dimensional (3D) visualization of the Web that has attempted to depict it in the form of a recognizable space; in other words, as a navigable landscape that may be visibly populated by its users. Our review begins by introducing a range of visualizations that address different aspects of using the Web. These include visualizations of Web structure, especially of links, that act as 3D maps; browsing history; searches; evolution of the Web; and the presence and activities of multiple users. We then summarize the different techniques that are employed by these visualizations. We conclude with a discussion of key challenges for the future.

A STUDY OF HEAT TRANSFER AND FLOW CHARACTERISTICS OF RISING TAYLOR BUBBLES

Practical application of flow boiling to ground- and space-based thermal management systems hinges on the ability to predict the system’s heat removal capabilities under expected operating conditions. Research in this field has shown that the heat transfer coefficient within two-phase heat exchangers can be largely dependent on the experienced flow regime. This finding has inspired an effort to develop mechanistic heat transfer models for each flow pattern which are likely to outperform traditional empirical correlations. As a contribution to the effort, this work aimed to identify the heat transfer mechanisms for the slug flow regime through analysis of individual Taylor bubbles. An experimental apparatus was developed to inject single vapor Taylor bubbles into co-currently flowing liquid HFE 7100. The heat transfer was measured as the bubble rose through a 6 mm inner diameter heated tube using an infrared thermography technique. High-speed flow visualization was obtained and the bubble film thickness measured in an adiabatic section. Experiments were conducted at various liquid mass fluxes (43-200 kg/m2s) and gravity levels (0.01g-1.8g) to characterize the effect of bubble drift velocity on the heat transfer mechanisms. Variable gravity testing was conducted during a NASA parabolic flight campaign. Results from the experiments showed that the drift velocity strongly affects the hydrodynamics and heat transfer of single elongated bubbles. At low gravity levels, bubbles exhibited shapes characteristic of capillary flows and the heat transfer enhancement due to the bubble was dominated by conduction through the thin film. At moderate to high gravity, traditional Taylor bubbles provided small values of enhancement within the film, but large peaks in the wake heat transfer occurred due to turbulent vortices induced by the film plunging into the trailing liquid slug. Characteristics of the wake heat transfer profiles were analyzed and related to the predicted velocity field. Results were compared and shown to agree with numerical simulations of colleagues from EPFL, Switzerland. In addition, a preliminary study was completed on the effect of a Taylor bubble passing through nucleate flow boiling, showing that the thinning thermal boundary layer within the film suppressed nucleation, thereby decreasing the heat transfer coefficient.

Equilibrium profiles of liquids in tilted Taylor-Hauksbee cells

In this work we study theoretically and experimentally the equilibrium profiles attained under spontaneous capillary rise of viscous liquids in the wedge-shaped narrow gap between two vertical plates intersecting at a tight angle α<<1. We contrast the differences among the case with vertical edge and those in which the arista is tilted to the vertical. Our theoretical description agrees well with experimental data for several analyzed inclinations.

Una Epistemología de la matematización del movimiento: caso de predicción y variación con la serie de Taylor y diferencias finitas

El estudio de predicción y variación de R. Cantoral (2001), así como la evolución a través de los marcos epistémícos del movimiento de: Aristóteles, Galileo y Newton (de la predicción de un estado conociendo un estado de facto Muñoz, 2000), proporcionan la base epistemológica para una epistemología inicial de la matematización del movimiento, y la búsqueda de los mecanismos de transición del binomio de Newton a la serie de Taylor; para ello revisamos textos antiguos, artículos relacionados con la investigación y textos escolares vigentes. Lo anterior nos proporcionó referentes para analizar la construcción de significados con los estudiantes de la carrera de Ingeniería Civil, así como incorporar contextos físicos donde las estrategias vertidas por los estudiantes para resolver problemas propios de la física, son de naturaleza tal que las ideas de cambio y variación están presentes (Solís, 1999). Nuestros resultados permitirán que los mecanismos de transición entre el binomio de Newton y la serie de Taylor profundicen las cuestiones teóricas y metodológicas para establecer la reorganización del discurso matemático escolar desde la matematización del movimiento y considerando como eje organizador la noción de predicción.

Ten Year Study on Water Flushing Times and Water Quality in Southern Taylor Slough, Everglades National Park, FL

The purpose of this research was to investigate the effects of wetland restoration on the water balance, flushing time, and water chemistry of southern Taylor Slough, a major water way in Everglades National Park. Water balance and flushing time equations were calculated on a monthly time step from 2001 – 2011. Water chemistry of major ions and nutrients were analyzed and correlated with water flushing times. Results showed that evapotranspiration followed by water volume had the greatest influence on flushing time. The flushing times varied between 3 and 78 days, with longer times observed between October and December, and the shorter times between March and May. Ion concentrations at the coastal areas decreased with increased flushing times. Increased surface water inflow that resulted from restoration projects and water management changes were productive in the rainy season and should result in increased flushing times and decreased ion concentrations in Taylor Slough.

Charles Taylor et la thèse des « langages plus subtils »

La thèse des « langages plus subtils » (subtler languages) constitue l’une des pièces maîtresses de la philosophie herméneutique de Charles Taylor. Elle nous situe à l’intersection de ce qu’il caractérise après Isaiah Berlin comme le tournant « expressiviste » du XVIIIe siècle (Herder, Hamann, Humboldt) ainsi que du tournant ontologique de l’herméneutique contemporaine (Heidegger, Gadamer, Ricoeur). Plus précisément, cette thèse permet d’expliquer pourquoi le tournant ontologique de l’herméneutique ne nous conduit pas au-delà de la tradition expressiviste, mais demeure un tournant au sein même de l’expressivisme. Notre objectif est de montrer, en ce sens, que la « subtilité » spécifique des langages philosophiques modernes devrait être comprise chez Taylor à partir de son interprétation originale de la sécularisation de l’occident chrétien.
