In this paper a model for the performance prediction and optimization of air coolers for indirect refrigeration systems is presented. The model applies for finned rube air coolers operating under frosting conditions and considers the transient heat and mass transfer between humid air and air cooler surfaces. The model is extended with an energy consumption analysis for the compression refrigera...

Protein structure prediction from sequence remains a major unsolved problem despite decades of work by the best minds in science. However, the availability of genome-scale data is changing the basis for the computational analysis of biological systems, and organizational patterns previously obscured by limited data sets now are becoming apparent. The opportunity to relate sequence, structure, a...

Most of the work on behavior prediction on the field of Qualitative Physics has focused on transient behavior and responses to perturbations (de Kleer Brown 1984; Forbus 1984; Kuipers 1985; Williams 1984); very little has been done about behavior of systems in steady state (Sussman & Steele 1980). understanding of the sinusoidal steady state of electrical circuits is important for several reaso...

We present the linear analysis of recent time filters used in numerical weather prediction. We focus on the accuracy and the stability of the leapfrog scheme combined with the Robert–Asselin–Williams filter, the higher-order Robert–Asselin type time filter, the compositetendency Robert–Asselin–Williams filter and a more discriminating filter.

This paper introduces Sybil, an interactive tool for assisting in the teaching of sound synthesis and processing. We have created a ‘browser’ in MSP that permits patchers to be assembled into a structured learning package. All the sophistication and flexibility of MSP is available. Sybil provides text accompanied by examples that students can manipulate in real-time, hearing the results and see...

The data fusion technique has been investigated by many researchers and has been used in implementing several information retrieval systems. However, the results from data fusion vary in different situations. To find out under which condition data fusion may lead to performance improvement is an important issue. In this paper, we present an analysis of the behaviour of several well-known method...

Monitoring on smartphones and mobile devices presents several challenges, such as limited battery power and computing resources, but also provides some unique opportunities, particularly the ability to capture contextual data. Incorporating the context of the activities being monitored could improve performance modeling. Real-time monitoring could also be used to facilitate contextaware applica...
