Gas Turbine-Based Binary Working Fluid Gas Compression Energy Storage System

open access: yes南方能源建设
[Objective] The efficiency of existing compressed air energy storage is insufficient, and site selection is restricted by gas storage conditions, which hinders large-scale deployment of compressed air energy storage.

An Efficient Application of Turbo Coding for OFDM In-Phase/Quadrature Index Modulation

open access: yesIEEE Access, 2023
We present a method to efficiently apply turbo coding to OFDM in-phase/quadrature index modulation (OFDM-IQ-IM) for both cases of presence and absence of puncturing.

An Energy Storage System with Binary Cycle Gas Compressionand Its Feasibility Analysis

open access: yes南方能源建设
[Introduction] The compressed air energy storage system has a very large air storage volume and high pressure, and usually uses the underground salt cavern as the gas storehouse. Project development is constrained by scarce salt cavern resources.

Hydrodynamic Performance Assessment of Selected Hydrokinetic Turbine Blade Sections in River Oyun, North-Central Nigeria [PDF]

open access: yesJournal of Renewable Energy and Environment
The hydrodynamic performance of lift-based hydrokinetic turbine rotors is typically dependent on the rotor blade sections, or the profile of the hydrofoil used.

Application of model updating techniques to turbomachinery rotor components

open access: yesAdvances in Mechanical Engineering, 2019
Model updating techniques are commonly used to improve simulation accuracy. Experimental data of component testing under laboratory conditions are normally used to improve analytical predictions of that component under operational conditions.

The effect of volute surface roughness on the performance of automotive turbocharger turbines

open access: yesJournal of the Global Power and Propulsion Society, 2017
The roughness level of the turbine housing’s internal surfaces can affect the total pressure loss, and hence the efficiency, of turbine stages for automotive turbochargers significantly.

Relay Switching Aided Turbo Coded Hybrid-ARQ for Correlated Fading Channel

open access: yes, 2011
Hybrid-Automatic-Repeat-reQuest (HARQ) has become an indispensable technique in reliable communications systems. However, its performance is inevitably affected by the channel’s fading correlation. In this paper, we proposed a novel relay-switching aided

Exit chart analysis of parallel data convolutional codes [PDF]

open access: yes, 2005
We recently proposed a new class of turbo-like codes called parallel data convolutional codes (PDCCs). The distinct characteristics of PDCCs include parallel data input bits and a self-iterative soft-in/soft-out a posteriori probability(APP) decoder. In

Assessment of the Impact of Turbo Factor on Image Quality and Tissue Volumetrics in Brain Magnetic Resonance Imaging Using the Three-Dimensional T1-Weighted (3D T1W) Sequence

open access: yesInternational Journal of Biomedical Imaging, 2023
Background. The 3D T1W turbo field echo sequence is a standard imaging method for acquiring high-contrast images of the brain. However, the contrast-to-noise ratio (CNR) can be affected by the turbo factor, which could affect the delineation and ...
