Video surveillance systems must support multiple streaming and prompt alert notification. We propose a two-tiered environment: a supervisor defines presentation layouts and model interface reactions to alerts; a surveillant watches synchronized videos, adapts layouts, and is notified with alerts.

L2 research has shown that instruction in L2 pragmatics is necessary. The current study evaluated the impact of explicit instruction on EFL learner's awareness and production of three speech acts of request, apology, and complaint. It also probed whether learners’ language proficiency plays any role in incorporating pragmatic instruction into the L2 classroom. Iranian undergraduate students maj...

A descriptive approach used, researchers developed a survey which distributed sample consisting 167 male female teachers. results indicated tha...

Expansion algorithm is a popular optimization method for labeling problems. For many common energies, each expansion step can be optimally solved with a min-cut/max flow algorithm. While the observed performance of max-flow for the expansion algorithm is fast, its theoretical time complexity is worse than linear in the number of pixels. Recently, Dynamic Programming (DP) was shown to be useful ...

AMUDALA BHASKER, AJAY BABU. Tiered-Service Fair Queueing (TSFQ): A Practical and Efficient Fair Queueing Algorithm. (Under the direction of Professor George N. Rouskas.) A router in today’s Internet has to satisfy two important properties in order to efficiently provide the Quality of Service (QoS) requested by the users. It should be fair among flows and also have low operational complexity. T...

Misconceptions, also known as alternate conceptions, about key concepts often hinder the ability of students to learn new knowledge. Concept inventories (CIs) are designed to assess students' understanding of key concepts, especially those prone to misconceptions. Two-tiered CIs include prompts that ask students to explain the logic behind their answer choice. Such two-tiered CIs afford an oppo...
