We consider a system model of a general finite–state machine (ratchet) that simultaneously interacts with three kinds of reservoirs: a heat reservoir, a work reservoir, and an information reservoir, the latter being taken to be a running digital tape whose symbols interact sequentially with the machine. As has been shown in earlier work, this finite–state machine can act as a demon (with memory...

This research was inspired by the need of a flexible and cost effective biometric security system. The flexibility of the wireless sensor network makes it a natural choice for data transmission. Swarm intelligence is used to optimize routing in distributed time varying network. In this paper, swarm intelligence maintains the required BER for varied channel conditions while consuming minimal ene...

Given a contact network that changes over time (say, day vs night connectivity), and the SIS (susceptible/infected/susceptible, flu like) virus propagation model, what can we say about its epidemic threshold? That is, can we determine when a small infection will “take-off” and create an epidemic? Consequently then, which nodes should we immunize to prevent an epidemic? This is a very real probl...

Networks consisting of vertices and edges connecting some pairs of vertices are powerful abstractions of relational data, hence have become very popular tools in many fields including sociology, biology and physics [1]. The characteristic of community structure in networks, i.e., networks are naturally divided into modules or communities, has attracted huge attention in the past decade which ca...

As one of the core components, the joint plays an important role during the movement of space manipulator, and its performance will be influenced by the existence of the backlash, which can severely sacrifice the quality of the manipulator to perform a task. In order to have a comprehensive understanding of the influence of the backlash to the gear transmission joints, a dynamic model of planet...

The concept of double stranded DNA forming triple helical complexes with a third strand of nucleic acids via so called Hoogsteenhydrogen bonds has been well established for the last 50 years. However, the topic reentered the big stage with recent publications pointing to an existence of these structures in vivo, highlighting their putative role in chromatin organization and transcriptional regu...

Connecting a complex control system with various sensors, actuators, and controllers as a networked control system by a shared data network can effectively reduce complicated wiring connections. This system is also easy to install and maintain. The recent trend is to use networked control systems for time-sensitive applications, such as remote dc motor actuation control. The performance of a ne...
