This document discusses signal detection and classification techniques in cognitive radio systems. It begins with an introduction to cognitive radio and the importance of spectrum sensing. It then reviews several existing spectrum sensing techniques, including matched filter detection and energy detection. The key focus is on cyclostationary feature detection, which exploits the periodicities in signal statistics. The document proposes combining cyclostationary analysis with support vector machines for signal detection and classification in cognitive radios. It describes selecting spectral coherence characteristic parameters and choosing the optimal kernel and parameters for the support vector machine classifier. Performance analysis is provided over Gaussian and IEEE 802.22 WRAN channels. The proposed approach is found to be more effective than other classifiers like binary decision trees and multilayer perceptrons,
Quality of supply and market regulation: survey within EuropeLeonardo ENERGY
Highlights:
* Appreciation of voltage quality is different from appreciation of reliability.
* Voltage quality consists of many different dimensions.
* Measurement of voltage quality needs special measurement devices.
* Cause of lack of voltage quality is often not as clear as lack of reliability.
* Determination of costs of lack of voltage quality is even more complicated.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Cognitive radio is a hot research area for future wireless communications in the recent years. In order to
increase the spectrum utilization, cognitive radio makes it possible for unlicensed users to access the spectrum
unoccupied by licensed users. Cognitive radio let the equipments more intelligent to communicate with each
other in a spectrum-aware manner and provide a new approach for the co-existence of multiple wireless
systems. The goal of this book is to provide highlights of the current research topics in the field of cognitive
radio systems. The book consists of 17 chapters, addressing various problems in cognitive radio systems.
