theory for eLearning
There has been much written about eLearning practice however little attention has been given to eLearning theory. After arguing that a lack of established theory will hinder further development in eLearning, this paper presents ten hypotheses for eLearning in an attempt to focus attention on the underlying principles that apply to eLearning in all situations.

Distributed Adaptive Cache Update Algorithm for the Dynamic Source Routing Protocol
On demand routing protocols use route caches to make routing decisions. Due to mobility, cached routes easily become stale. To address the cache staleness issue, prior work in DSR used heuristics with ad hoc parameters to predict the lifetime of a link or a route. However, heuristics cannot accurately predict timeouts because topology changes are […]
Gait Recognition using Dynamic Affine Invariants
We present a method for recognizing classes of human gaits from video sequences. We propose a novel image based representation for human gaits. At any instance of time a gait is represented by a vector of affine invariant moments. The invariants are computed on the binary silhouettes corresponding to the moving body. We represent the […]
