Protein electrostatic states have been demonstrated to play crucial roles in catalysis, ligand binding, protein stability, and in the modulation of allosteric effects. Electrostatics states are demonstrated to appear conserved among DEAD-box motifs and evidence is presented that the structural changes that occur to DEAD box proteins upon ligand binding alter the DEAD-box motif electrostatics in...

The “mobility” has two important aspects: i) how to support mobility and ii) how to exploit mobility. This paper considers the latter, while many existing works only consider the former. This work is trying to prove that system performance will be greatly improved by understanding a user’s movement. In this paper, we propose a novel location update protocol, called SLUP which minimizes the ener...

Dead Reckoning mechanism allows to reduce the network bandwidth utilization considerably. As available bandwith is the key problem for large DIS, we expect that a Dead Reckoning mechanism will allow to increase the number of entities involved in a DIS exercise. In this paper we model a Dead Reckoning mechanism and we present an evaluation of its performance. Such a mechanism reduces the number ...

An important aspect of location-aware services is the management of location information. To this end, location information needs to be transferred from a mobile device, which determines this information by means of a local positioning sensor (such as GPS), to a location service, where the location information can be queried by applications. Because bandwidth in wide area mobile communications ...

Dead Reckoning mechanism allows reducing the network utilization considerably when used in Distributed Interactive Simulation Applications. However, this technique often ignores available contextual information that may be influential to the state of an entity, sacrificing remote predictive accuracy in favor of low computational complexity. The remainder of this paper focuses on the analysis of...

In today’s gaming world, a player expects the same play experience whether playing on a local network or online with many geographically distant players on congested networks. Because of delay and loss, there may be discrepancies in the simulated environment from player to player, likely resulting in incorrect perception of events. It is desirable to develop methods that minimize this problem. ...

Natural disasters are a large threat for people especially in developing countries such as Laos. ICT-based disaster management systems aim at supporting disaster warning and response efforts. However, the ability to directly communicate in both directions between local and administrative level is often not supported, and a tight integration into administrative workflows is missing. In this pape...

First, we briefly introduce the technologies of PDR (Pedestrian Dead Reckoning) that can be used to track the location and orientation of a pedestrian. Secondly, we show some enhancement of the PDR to improve its performance on accuracy. Finally, we describe the applications of the PDR.
