This document presents MPEG-4 Animation Framework eXtension (AFX), a recent amendment to the MPEG-4 Systems specification. AFX defines high-level geometry, texture, volume, and animation components for enhanced interactive multimedia applications.

operation is not done as frequently as it should be. I admit, of course, that we are all agreed that myomectomy is a good operation, and that each one is doing it according to his lights. My aim to-night will be to define the very broad limits of the operation, to emphasise its safety, and to show its feasibility and success under conditions which, so far as I can judge, would, by many, be term...

The water quality of urban rivers in China has undergone significant improvement since the 13th Five-Year Plan period (2016–2020). Among these, Shenzhen are most representative. Assessing historical trends and analyzing driving forces river is great importance provides valuable insights. This study selects two typical watersheds, Maozhou River Longgang River, to explore how link with control pr...

We describe a novel depth image-based representation (DIBR) that has been adopted into MPEG-4 Animation Framework eXtension (AFX). The idea of this approach is to build a compact representation of a 3D object or scene without storing the geometry information in traditional polygonal form. The main formats of the DIBR family are SimpleTexture (an image together with depth array), PointTexture (a...

In the present paper a geospatial analysis is performed to understand the meandering behaviour of Barak River in southern Assam between 1988 and 2010. Landsat images (with Thematic mapper and Enhanced thematic mapper-plus sensors) for years 1988, 1999, and 2010 are considered for the study. River Barak within the study area is digitized as polygons for three years and sinuosity index (SI) are c...

Mediterranean fluvial environments have responded sensitively to past changes in climate, physiographic conditions and human activity. Chronosequences of river terraces and alluvial deposits were established using morphologic, sedimentological and pedologic criteria, Cand Pb-dating techniques, historical data and pottery fragments. The objective of this study addresses the fluvial dynamic of se...

The department of Curriculum and Instruction at Iowa State University, USA offers a leading residential program of information communication technology (ICT) in teacher education. Based on the success of this program, in 2003, faculty members and instructional developers at Iowa State University Center for Technology in Learning and Teaching (http://www.ctlt.iastate.edu) created an online maste...

Financial innovation in an existing asset generically supports a Pareto improvement, targeting the income effect. This result, as several on taxation, owes to one unifying notion: that an intervention generically supports Pareto improvements if the implied price adjustment is sufficiently sensitive to the economy’s risk aversion. Elul (1995) and Cass and Citanna (1998) introduce financial innov...

The first Circumpolar Health symposium took place in Fairbanks in 1967. Approximately every three years since, an increasing number of researchers have met to present and discuss the health conditions of the North. We analysed the proceedings from the 11 congresses and the abstracts from the 12th congress in 2003 and found a shift of focus from biology to sociology of health. Today, circumpolar...

N December 10, 2003, the Bureau of Economic Analysis (BEA) will release the results of the 12th comprehensive, or benchmark, revision of the national income and product accounts (NIPAs). The last such revision was released in October 1999. This article, which describes statistical changes, is the fourth in a series of SURVEY OF CURRENT BUSINESS articles about the comprehensive revision. An arti...
