This document summarizes research on improving web performance through integrated web prefetching and caching. It discusses how web prefetching can reduce latency by predicting and fetching web pages before they are requested. An integrated architecture reserves cache space for prefetched pages. By analyzing web logs to build prediction models of frequent paths, it aims to improve performance over caching alone. The tradeoff between reduced latency and potential increased network load is analyzed. Several previous works studying prefetching and caching algorithms individually are reviewed. The goal is a seamless prefetching system that works with existing caching systems.
Acids turn litmus paper red, contain hydrogen, and donate protons. Bases turn litmus paper blue, contain hydroxide ions, and accept protons. When acids and bases are mixed in a neutralization reaction, they form salts and water by combining hydrogen ions with hydroxide ions. The pH scale measures the hydrogen ion concentration to determine if a solution is acidic, basic, or neutral.
This document discusses using k-means clustering to classify Indian black tea samples based on impedance spectroscopy data from an "impedance tongue" sensor array. It provides background on impedance tongue sensors and k-means clustering. The document then describes applying k-means clustering to impedance response data from 120 tea samples measured at different voltages/frequencies, obtaining classification rates from 87-96%. It concludes that k-means clustering is effective for distinguishing tea samples with minimum intra-cluster and maximum inter-cluster distances.
Babylon 5 returns with an original movie from creator J. Michael Straczynski. The movie features original cast members Bruce Boxleitner, Tracy Scoggins, and Peter Woodward, and includes marketing support and the never-before-seen Straczynski Diaries giving an inside look at the film's creation.
The Go West Project aims to study and document the development of new cities in China's interior through focusing on themes of people, money, city development, nature, and identity. The project founders plan to publish their findings in a book to be presented at the 2010 Shanghai Expo, as well as in magazines and presentations. They are seeking partners and sponsors to participate in accumulating knowledge about China's "invisible cities" and help fund publishing the book.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
El documento define multimedia como cualquier combinación de texto, gráficos, sonido, animación y video que llega a través de computadoras u otros medios electrónicos. Explica que multimedia interactiva permite al usuario controlar elementos como cuándo se presentan, mientras que hipermedia ofrece una estructura de enlaces para que el usuario navegue. También describe dispositivos de almacenamiento como discos flexibles y discos duros, así como herramientas para crear gráficos y diseños asistidos por computadora.
Este documento provee información sobre los desórdenes alimenticios como la anorexia nerviosa y la bulimia nerviosa. Explica que estos trastornos son el resultado de factores psicológicos, familiares, genéticos, ambientales y sociales. También describe los síntomas y posibles complicaciones médicas de cada trastorno y resalta la importancia de buscar tratamiento médico y terapéutico para poder recuperarse de manera saludable.
Este documento presenta resúmenes breves de 11 famosas fotografías históricas, incluyendo la imagen del Che Guevara tomada por Alberto Korda, la agonía de Omayra Sánchez atrapada en el lodo durante la erupción del Nevado del Ruiz, la niña del Vietnam Phan Thi Kim Phuc después de ser quemada por napalm, la ejecución de un prisionero del Vietcong en Saigón, la niña afgana Sharbat Gula fotografiada por Steve McCurry, el beso en Times Square que celebró el

The document discusses various computer viruses, hacking techniques, and security measures. It describes the Code Red and Love Bug viruses from 2001. It then explains biometric security methods like voice recognition, retina scans, and fingerprint scans that only allow access for an individual. However, biometric data can sometimes be replicated. The document also covers phishing scams, advantages of biometric security, disadvantages, antivirus software, and types of sensitive information that should be encrypted like passwords, credit card numbers, and social security numbers.
This document outlines the goals and structure of a workshop aimed at developing entrepreneurial and business skills for scientists. The workshop will involve short lectures, hands-on work guided by coaches, and focus on applying research and innovation to develop careers in academia, business, or as entrepreneurs. The overall goal is to prepare scientists to think entrepreneurially regardless of their specific career path.
This document summarizes and analyzes the security of an existing fair e-cash payment system based on DSA signatures. It identifies flaws that allow forgery of e-cash and repudiation of transactions. The author then proposes improvements to the system to address these security issues and ensure fairness, integrity and authentication between parties. The improved system aims to prevent insider attacks and misbehaviors from participants in transactions.
Using Benchmarking to Catalyze Greater Energy EfficiencyCliff Majersik
This document discusses benchmarking building energy usage and improving energy efficiency. It summarizes that benchmarking uses data to compare a building's energy usage to similar buildings. The EPA's Portfolio Manager tool is commonly used for benchmarking. The document also discusses how the Green Button initiative could increase access to energy usage data from utilities in a standardized format to help with benchmarking and identifying savings opportunities. Next steps include evaluating how Green Button data can best be used for benchmarking in Portfolio Manager.
This document discusses the uncertainty of predicting the future and encourages being fully present and engaged in the current moment. It also recommends trying new ideas and technologies, providing examples like the Internet, digital music, and social media platforms that emerged through experimentation rather than prediction. The overall message is that the future is shaped by focusing on opportunities in the present rather than attempting to foresee what has not yet occurred.
El Ministerio de Economía anunció los nuevos precios de referencia para el diesel y la gasolina a partir del 16 de febrero de 2009. Se analizaron los precios al consumidor en Estados Unidos y cómo afectaron la aplicación de la fórmula de precios en El Salvador. También se compararon los precios en El Salvador con otros países de Centroamérica, encontrando que eran los más bajos de la región. Finalmente, se examinaron los precios en el mercado de Estados Unidos y El Salvador.
