General Signal Model for Multiple-Input Multiple-Output GMTI Radar

Sensors, 2018
Multiple-input multiple-output (MIMO) ground moving target indication (GMTI) radar has been studied recently because of its excellent performance. In this paper, a general signal model is established for the MIMO GMTI radar with both fast-time and slow ...

An Unusual Case of Cutaneous Nocardia cyriacigeorgica Infection Assuming the Appearance of Shingles

Case Reports in Infectious Diseases, Volume 2026, Issue 1, 2026.
Nocardia is an opportunistic organism that commonly infects the lungs of the immunocompromised and can cause disseminated infections. Diagnosis of Nocardia cyriacigeorgica is through culture and susceptibilities, aided by 16S rRNA sequencing. We report a case of a shingles‐like rash eruption due to Nocardia cyriacigeorgica in a 69‐year‐old patient with

A Non-Cooperative Approach to the Joint Subcarrier and Power Allocation Problem in Multi-Service SCFDMA Networks

EAI Endorsed Transactions on Mobile Communications and Applications, 2016
In this paper a joint resource allocation problem is studied in a multi-service Single Carrier FDMA (SC-FDMA) wireless network. Mobile users request various services with different Quality of Service (QoS) characteristics and they determine in a ...

Multiple transmit antennas for low PAPR spatial modulation in SC-FDMA: single vs. multiple streams

EURASIP Journal on Wireless Communications and Networking, 2020
The main reason for the selection of single-carrier frequency division multiple access (SC-FDMA) modulation technique in mobile high data rate communications lays in its low value of peak-to-average power ratio (PAPR).

Multimedia Channel Allocation in Cognitive Radio Networks using FDM-FDMA and OFDM-FDMA

, 2016
In conventional wireless systems, unless a contiguous frequency band with width at least equal to the required bandwidth is obtained, multimedia communication can not be effected with the desired Quality of Service. We propose here a novel channel allocation technique to overcome this limitation in a Cognitive Radio Network which is based on utilizing ...

Challenges, models, and algorithms for flow and transport simulations in deep reservoirs

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 638-650, December 2025.
Deep reservoirs are considered a promising resource for future energy supply, but current reservoir simulation technologies may face certain challenges if they are directly used in specific scenarios in deep reservoir development. Models and algorithms were developed to resolve these challenges, including a better phase equilibrium model, a better ...
