Blind Interleaver Parameter Estimation From Scant Data

IEEE Access, 2020
A method for blind estimation of interleaver parameter was recently reported which made additional data from a limited amount of received data. However, the process of making additional data creates undesirable linearity which degrades estimation ...

Non-Cooperative Spectrum Sensing Based on Cyclostationary Model of Digital Signals in the Context of Cognitive Radio

Engineering, 2021
This paper addresses the problem of the opportunistic spectrum access in Cognitive Radio. Indeed, most spectrum sensing algorithms suffer from a high computational cost to achieve the detection process. They need a prior knowledge of signal characteristics and present a bad performance in low Signal to Noise Ratio (SNR) environment.

Effect of cooperation level of group on punishment for non-cooperators: a functional magnetic resonance imaging study. [PDF]

PLoS ONE, 2012
Sometimes we punish non-cooperators in our society. Such behavior could be derived from aversive emotion for inequity (inequity aversion) to make non-cooperators cooperative.

Arginine vasotocin regulation of interspecific cooperative behaviour in a cleaner fish. [PDF]

PLoS ONE, 2012
In an interspecific cooperative context, individuals must be prepared to tolerate close interactive proximity to other species but also need to be able to respond to relevant social stimuli in the most appropriate manner.

Noncooperative Spectrum Sensing Strategy Based on Recurrence Quantification Analysis in the Context of the Cognitive Radio

Signals, 2023
This paper addresses the problem of noncooperative spectrum sensing in very low signal-to-noise ratio (SNR) conditions. In our approach, detecting an unoccupied bandwidth consists of detecting the presence or absence of a communication signal on this bandwidth.

Automatic Access Control Based on Face and Hand Biometrics in a Non-cooperative Context

2018 IEEE Winter Applications of Computer Vision Workshops (WACVW), 2018
Automatic access control systems (ACS) based on the human biometrics or physical tokens are widely employed in public and private areas. Yet these systems, in their conventional forms, are restricted to active interaction from theusers. In scenarios where users are not cooperating with the system, these systems are challenged.

Different responses to reward comparisons by three primate species. [PDF]

PLoS ONE, 2013
BackgroundRecently, much attention has been paid to the role of cooperative breeding in the evolution of behavior. In many measures, cooperative breeders are more prosocial than non-cooperatively breeding species, including being more likely to actively ...

Effectiveness of cooperative grouping in developing reading skills of university level EFL learners

Journal of Language and Education, 2023
Background. Collaborative Strategic Reading (CSR) is an instructional method in which students work together in a cooperative framework, jointly construct a model of text and come to its potential meaning through discussions. Purpose.

Cooperative and non-cooperative sense-and-avoid in the CNS+A context: A unified methodology

2016 International Conference on Unmanned Aircraft Systems (ICUAS), 2016
A unified approach to cooperative and non-cooperative Sense-and-Avoid (SAA) is presented that addresses the technical and regulatory challenges of Unmanned Aircraft Systems (UAS) integration into non-segregated airspace. In this paper, state-of-the-art sensor/system technologies for cooperative and non-cooperative SAA are reviewed and a reference ...
