This paper uses packet-level ns2 network simulations to study the impacts of TCP and network-level effects on userperceived Web performance in Web proxy caching hierarchies. We model a simple two-level Web proxy caching hierarchy, and study the effects of link speed, propagation delay, request arrival rate, cache hit ratio, and cache management policy on the transfer latency for Web document do...

In this paper we propose a new approach for tonic identification in Indian art music and present a proposal for a complete iterative system for the same. Our method splits the task of tonic pitch identification into two stages. In the first stage, which is applicable to both vocal and instrumental music, we perform a multi-pitch analysis of the audio signal to identify the tonic pitch-class. Mu...

Using a two-stage growth curve analysis, change over time in performance on tests in the Halstead-Reitan Battery and Average Impairment Rating (AIR) was assessed for 53 individuals who varied in age and health status. In the first stage of the analysis, estimated slope and intercept values were calculated for each individual by regressing longitudinal data points on time. In the second stage, e...

This paper describes novel concepts for the interactive composition of artistic real-time graphics, so-called live visuals. By establishing two fundamental techniques dealing with the structured media integration and the intrinsic design process, we significantly increase the efficiency of interactive editing in live visuals applications. First, we present a media manager that supports the user...

Within a worldwide business-strategic project the development of a software system requires a methodology to monitor resources consumption and service levels since high level design. IRIDIUM ® is a digital communication network based on satellites, designed to provide personal mobile services anywhere on earth. Telesoft developed an Operation and Maintenance Center for the Iridium's Gateways an...

RZBENCH is a benchmark suite that was specifically developed to reflect the requirements of scientific supercomputer users at the University of ErlangenNuremberg (FAU). It comprises a number of application and low-level codes under a common build infrastructure that fosters maintainability and expandability. This paper reviews the structure of the suite and briefly introduces the most relevant ...

In learning and development, self-regulation can be described as the degree to which individuals are metacognitively, motivationally, and behaviourally proactive participants in their learning process (Zimmerman, 1989, 2006). We examined the relationship between self-regulation and performance level in elite (n=159) and nonelite (n=285) youth soccer players aged 11 to 17 years (mean age 14.5, s...

Skilled musicians are able to shape a given piece of music (by continuously modulating aspects like tempo, loudness, etc.) to communicate high level information such as musical structure and emotion. This activity is commonly referred to as expressive music performance. The present paper presents another step towards the automatic high-level analysis of this elusive phenomenon with AI methods. ...

A study was conducted to evaluate the effect of feeding different levels of protein to black Baladi breed kids. Weanling Baladi kids (n=18; 75 to 90 days old) were selected and individually housed at our experimental farm. Kids were divided randomly to one of the three treatments for 12 weeks. The three dietary treatments were: T1: control ration, formulated according to NRC to cover the protei...
