Improving biomedical image quality with computers

Computerized image enhancement techniques used on biomedical radiographs and photomicrograph

Digital computer processing of X-ray photos

Digital computers correct various distortions in medical and biological photographs. One of the principal methods of computer enhancement involves the use of a two-dimensional digital filter to modify the frequency spectrum of the picture. Another computer processing method is image subtraction

Interacción humano computadora mediante interfaces hápticas en RV

Los dispositivos hápticos son aquellos que permiten a un usuario tener una realimentación de información a través del tacto o de la aplicación de fuerzas sobre el cuerpo. La incorporación de dispositivos hápticos en RV puede permitir al usuario una mayor inmersión en el mundo virtual. El objetivo de este trabajo es diseñar y desarrollar interfaces hápticas usa bles en el contexto de RV. Obtener una tecnología que reduzca los costos involucrados, logrando una mayor inserción de las interfaces hápticas. Crear una solución de alta usabilidad pero de bajo costo para proveer realimentación sensorial táctil en RV.Área: TICs, Electrónica e Informátic

THE 2001 SUPERMARKET PANEL ANNUAL REPORT

The Supermarket Panel collects data annually from individual supermarkets on store characteristics, operations, and performance. It was established in 1998 by the Food Industry Center as the basis for ongoing study of the supermarket industry. The Panel is unique because the unit of analysis is the individual store and the same stores are tracked over time. This makes it possible to analyze the processes by which new technologies, business practices, and competitive forces are changing the industry. The 2001 Supermarket Panel consists of 563 stores selected at random from the nearly 32,000 supermarkets in the U.S. or invited to participate through their affiliation with IGA. These 563 stores are located in forty-seven states and the District of Columbia. They are a representative cross section of the industry, including stores from all formats that belong to ownership groups ranging from single stores to the country's largest chains.Agribusiness, Industrial Organization, Marketing,
