A self-reconfigurable robot can be viewed as a network of many autonomous modules. Driven by their local information, the modules can initiate tasks that may conflict with each other at the global level. How the modules negotiate and select a coherent task among many competing tasks is thus a critical problem for the control of self-reconfigurable robots. This paper presents a distributed algor...

We propose a computational model for the self-organization of feature columns based on a modular framework. The proposed model consists of several modules; each module is composed of a collection of Gaussian units. The combination of hierarchical competition within and between modules and a smoothness constraint finds out continuity among input patterns, and topographically maps these series of...

background: to study the influence values of self-management program intervention on efficacy of emotion regulation for patients suffering from chronic obstructive pulmonary disease (copd). methods: eighty-six diagnosed chronic copd patients in stable phase in linzi district people's hospital, zibo shandong province, pr china from june 2014 to june 2015 were selected in succession. they were di...

The configuration management of a sensor network composed of tens or up to thousands of nodes is difficult due to the limit of memory space and energy consumption. This paper presents an approach for dynamic reconfiguration of application modules in sensor networks based on Nano-Qplus. The version information from proposed methods is registered into NVSync (Nano-Qplus Version Synchronization), ...

In the present paper we show that a set of self-organizing modules can produce complex Behaviors in a robot consisting of a Car that carries an articulated arm. The free end of the arm has an IR sensor that senses an environmental IR Beacon. The self-organization is implemented through self-inactivating modules. Every module moves, stepwise, a different motor(or set of concurrent motors) of the...

We present a concurrent and real-time task management method for distributed control of modules in a self-reconfigurable robot. This method is essential for modules to simultaneously control multiple behaviors in real-time and supporting a concurrent programming style that will greatly ease the development of control software for large-scale reconfigurable robots. Although real-time operating s...

The self-reconfigurable modular robot consists of many identical modules. By connecting to/disconnecting from other modules, the whole structure of the robot can transform into arbitrary other configurations. First, the lattice-type self-reconfigurable modular robot is proposed and its disconnected/connected mechanism is analyzed, which can finish self-morphing action. Second, the basic configu...

This paper studies the vanishing of $Ext$ modules over group rings. Let $R$ be a commutative noetherian ring and $ga$ a group. We provide a criterion under which the vanishing of self extensions of a finitely generated $Rga$-module $M$ forces it to be projective. Using this result, it is shown that $Rga$ satisfies the Auslander-Reiten conjecture, whenever $R$ has finite global dimension and $ga...

we investigate the problem of the existence of a frame forright ideals of a c*-algebra a, without the use of the kasparov stabilizationtheorem. we show that this property can not characterize a as a c*-algebraof compact operators.
