Joint Radar Jamming and Communication System Design Based on Universal Filtered Multicarrier Chirp Waveform

Remote Sensing
In this article, we propose a joint waveform based on universal filtered multicarrier (UFMC) chirp for radar jamming and communication joint systems. Modulation of radar jamming chirp signals and communication signals on different subcarrier groups in ...

A novel multi-fold security framework for cognitive radio wireless ad-hoc networks [PDF]

, 2012
Cognitive Radio (CR) Technology has emerged as a smart and intelligent technology to address the problem of spectrum scarcity and its under-utilization. CR nodes sense the environment for vacant channels, exchange control information, and agree upon free

Buchanan and the Social Contract: Coordination Failures and the Atrophy of Property Rights

Southern Economic Journal, EarlyView.
ABSTRACT James Buchanan advocated that societies should be based on a social contract. He rejected anarchy, seeing it as a “Hobbesian jungle” that calls for government intervention to maintain social order. He also opposed theories of spontaneous order. These views led to debates about the compatibility of Buchanan's works with classical liberalism and

The History and Ideas of George Herbert Mead's Pragmatism and Its Relevance for Operational Research and Systems Thinkers

Systems Research and Behavioral Science, EarlyView.
ABSTRACT George Herbert Mead is an oft forgotten or ignored American philosopher who was one of the originators of pragmatism. Today, he is recognised as a creative thinker who has teased out knotty problems that others in the field had not realised were problems. Understanding Mead's analysis has been made difficult because he died prematurely without

“I'm a Good Guy Who Deserves Better, Yet Nobody Wants to Give me Better”: The Accounts of Nice Guys

Symbolic Interaction, EarlyView.
Within Western popular culture and online discourse, a “Nice Guy” is someone who enacts niceness for which they believe they are owed, deserving of, or entitled to something in return—especially the romantic or sexual attention of women. In this study, we examine the use of accounts in personal narratives told in an anonymous online discussion forum ...
