Automatic programming of insertions is an essential step in achieving a truly flexible manufacturing environment. We present techniques based on active compliance implemented with hybrid force-position control capable of inserting a wide variety of shaped pegs. These techniques provide a significant step towards an automatically programmed flexible manufacturing environment. It will be necessar...

Spectrum resources management of growing demands is a challenging problem and Cognitive Radio (CR) known to be capable of improving the spectrum utilization. Recently, Power Spectral Density (PSD) map is defined to enable the CR to reuse the frequency resources regarding to the area. For this reason, the sensed PSDs are collected by the distributed sensors in the area and fused by a Fusion Cent...

—Disaster relief networks are designed to be adaptable and resilient so to encompass the demands of the emergency service. Cognitive Radio enhanced ad-hoc architecture has been put forward as a candidate to enable such networks. Spectrum sensing, the cornerstone of the Cognitive Radio paradigm, has been the focus of intensive research, from which the main conclusion was that its performance can...

Rapid growth of wireless communication and limited spectrum availability to support the applications and services, has led to the development of cognitive radio as promising solution to address the problem of spectrum scarcity. Spectrum sensing is one of the fundamental functions towards the implementation of the cognitive radio concept in wireless communication. In this paper, we present an ad...

This paper proposes a censored and ordered sequential collaborative spectrum sensing scheme for cognitive radio ad hoc network (CRAHN). The scheme uses the ordered of the sensing data reliability for enabling the Dempster Shafer theory of evidence sequential combination. A preceding censored process removes the nodes having insignificant sensing data to the broadcasting sensing result process. ...

This paper proposes an optimal cooperative spectrum sensing scheme, based on the criterion of deflection coefficient maximization of the global decision statistic. Multiple cooperative secondary users serve in the cognitive radio network to provide space diversity for spectrum sensing. After the fusion center acquires the optimal fusion weights, an optimal global threshold setting strategy is u...
