A Stochastic Geometry Analysis of Hybrid Cellular-Adhoc CDMA Networks

open access: yesInternational Journal of Information and Communication Technology Research, 2011
This paper studies the impact of using multihop wireless adhoc network in conjunction with cellular networks under a probabilistic routing strategy. Our objective is to obtain the outage probability of the twodimensional hybrid CDMA network under path ...

Estimating Wind‐Power Capacity Time Series From Production Data Using a Power Curve Model and Quadratic Optimization

open access: yesWind Energy, Volume 29, Issue 8, August 2026.
ABSTRACT Accurate, time‐resolved installed capacity data are crucial for forecasting and analysing wind‐power production. The time series of installed capacity is often only approximately known in regions with rapid wind power development. Public wind power databases may only be updated yearly and installation dates may not be differentiated within ...

Cybersecurity in aquaculture: Risks, governance, and future directions across production systems

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 4, August 2026.
Abstract Aquaculture is becoming increasingly dependent on connected sensors, remote monitoring, edge and cloud analytics, automation, and digital traceability; however, the cybersecurity evidence base remains fragmented and low‐trophic systems are markedly underrepresented.

Distributed beamforming and power allocation for cooperative networks. [PDF]

open access: yes, 2008
Cooperative diversity systems rely on using relay nodes to relay copies of transmitted information to the destination such that each copy experiences different channel fading, hence increasing the diversity of the system.

CyberGeoAI For Intelligent Spatial Decision Support

open access: yesTransactions in GIS, Volume 30, Issue 5, August 2026.
ABSTRACT The evolution of spatial decision support systems (SDSS) is being rapidly shaped by the integration of Cyberinfrastructure (CI) and Geospatial Artificial Intelligence (GeoAI), collectively referred to as CyberGeoAI. The rise of big data, complex decision environments, and computing power gives opportunities for advanced tool development to ...

Direct Observations of Large‐Scale Wave Structure and Post‐Sunset Rise of the Ionosphere in the Generation of Equatorial Spread F

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large‐scale wave structure (LSWS) and the post‐sunset rise (PSSR) are two key factors in the generation of equatorial spread F (ESF). In this study, we reported continuous and direct observations of LSWS and PSSR and their effects on seeding ESF by Sanya incoherent scatter radar (SYISR) and ionosonde in September–October 2024.

Outage Probability in a Multi-Cellular Network Using Alamouti Scheme [PDF]

open access: yes, 2010
In this paper we analyze the performance of a downlink single user multi-cellular multiple inputs single output (MISO) system using the Alamouti code. We derive, for the first time, an analytical expression of the cumulative distribution function of the ...
