The use of the metabolism concept, expanded to include aspects of livability, is applied to cities to demonstrate the practical meaning of sustainability. Its application in industrial ecology, urban ecology, urban demonstration projects, business plans and city comparisons are used to illustrate its potential. # 1999 Elsevier Science B.V.

FAUST is a compiled language designed for real-time audio signal processing. It is a free software published under the terms of the GNU General Public License. Sources and binaries are available at source forge : http://faudiostream.sourceforge.net. The demonstration will give an overview of the main features of the language and the compiler through several simple and practical examples.

Passage-time densities are important for the detailed performance analysis of distributed computer and communicating systems. We provide a proof and demonstration of a practical iterative algorithm for extracting complete passage-time densities from expressive semi-Markov systems. We end by showing its application to a distributed web-server cluster model of 15.9 million states.

We propose a GA ray-tracing method which applies a genetic algorithm to ray tracing in order to complete the large-scale computation of estimating radio propagation in a practical amount of time. We describe the GA ray-tracing method as well as a demonstration of its effectiveness through numerical simulation .

the purpose of the present study was to compare the effects of two methods of self-modeling and video demonstration of an expert on the acquisition and retention of volleyball serve skill. participants were 30 students (aged between 12 and 14) who were assigned into two homogeneous groups after the pretest. the self-modeling group (n = 15) watched their performances in the criterion task via a ...

In August of 1997, The US National Automated Highway System Consortium (NAHSC) presented a proof of technical feasibility demonstration of automated driving. The 97 Demo took place on car-pool lanes on I15 in San Diego, California. Members of the Consortium demonstrated many different functions, including: Vision-based road following Lane departure warning Magnetic nail following Radar reflecti...

purpose: the present study aims at comparing the impact of two teaching/learning approaches-self- directed/paced learning and lecture/demonstration-based instruction-on mastering psychomotor skills among nursing students. material & method: thirty nursing students were selected for the study. they filled out questionnaires indicating the demographic factor, and mean exam scores achieved in the ...

A pairwise balanced design is an ordered pair S,B , denoted PBD S,B , where S is a finite set of symbols, and B is a collection of subsets of S called blocks, such that each pair of distinct elements of S occurs together in exactly one block of B. Here |S| v is called the order of the PBD. Note that there is no condition on the size of the blocks in B. If all blocks are of the same size k, then...
