Initiatives to stimulate the development and propagation of open educational resources (OER) need a sufficiently large community that can be mobilized to participate in this endeavour. Failure to achieve this could lead to underuse of OER. In the context of the Wikiwijs initiative a large scale survey was undertaken amongst primary and secondary school teachers to explore possible determinants ...

Mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without the need of fixed infrastructure or a wired backbone network. Due to limited transmission range node to exchange information with any other node in the network. Thus routing is a crucial issue in the design of MANET. On-demand routing protocols for mobile ad ...

Recently it was proved that the group of rough paths modulo tree-like equivalence is isomorphic to the corresponding signature group through the signature map S (a generalized notion of taking iterated path integrals). However, the proof of this uniqueness result does not contain any information on how to “see” the trajectory of a (tree-reduced) rough path from its signature, and a constructive...

Active vibration control (AVC) can solve many problems. However, structural in underwater vehicles often involves other factors such as complex excitation and path coupling, etc. At present, the traditional algorithm (e.g., multi Filtered-x Least Mean Square, M-FxLMS) usually cannot effectively process multi-frequency coupling effects of multi-secondary path, which will affect its convergence s...

Peachtree City is a city with a secondary transportation network, known as the path system. This paper seeks to determine why the path system is so successful and whether there are fundamental spatial, configurational properties which underpin its achievement. This paper examines the axial-line network of paths as a distinct network then as part of the larger, combined system of both paths and ...

In this piece of work, we compare the effectiveness of distributed restoration path computation methods that use head-end precomputation and do not use backup path sharing. Our aim is to provide statistics on primary and secondary path lengths of simple disjoint path computation methods in real-world network topologies. Moreover, we propose a path computation method which can be used when paths...

In this paper, we propose the introduction of a frequency domain variable perturbation control and a leaky algorithm to the frequency domain time difference simultaneous perturbation (FDTDSP) method in order to improve the cancellation performance and the stability of the active noise control (ANC) system using the perturbation method. Since the ANC system using the perturbation method does not...
