This study aims to reveal how the embodied cognition of certain geometrical concepts secondary-school students arises via gestures and what kinds they produce while engaging with different concepts. The participants comprised four eleventh-grade studying at a state high school in Turkey. focused on related angle, measure an congruence-similarity, translation. Data were gathered video-recorded f...

To support the diverse Quality of Service (QoS) requirements of real-time (e.g. audio/video) applications in integrated services networks, several routing algorithms that allow for the reservation of the needed bandwidth over a Virtual Circuit (VC) established on one of several candidate routes have been proposed. Traditionally, such routing is done using the least-loaded concept, and thus resu...

In Mobile Ad hoc Network (MANET), single path QoS routing is disadvantageous since it may cause fading, interference, collision and link failures. For QoS routing, load balancing is essential since it allows a router to take advantage of multiple best paths to a given destination. It can minimize the maximum utilization while supporting the same traffic demands. It reacts quickly to changes in ...

Web page load time is a key performance metric that many techniques aim to reduce. Unfortunately, the complexity of modern Web pages makes it difficult to identify performance bottlenecks. We present WProf, a lightweight in-browser profiler that produces a detailed dependency graph of the activities that make up a page load. WProf is based on a model we developed to capture the constraints betw...

Recently, a two-phase handoff protocol has been adopted to support the rerouting of the connection after intercluster handoff. It employs rapid path extension for the first phase, followed by path optimization to establish the new connection in the second phase. The path optimization becomes costly in terms of the signaling and processing load on the ATM network in order to determine the optima...

The establishment of inter-domain traffic engineered paths is a requisite to accomplishing an end-to-end bandwidth guarantee and end-to-end resource optimization. Though the inter-domain paths must be reliable, it is difficult to compute suitable backup inter-domain paths in advance when the traffic engineering information is not disclosed outside of each domain. This means that the inter-domai...
