Optimization of carbon dioxide absorption in a continuous bubble column reactor using response surface methodology
(WILEY, 2023)Carbon dioxide absorption using amine based solvents is a well-known approach for carbon dioxide removal. Especially with the increasing concerns about greenhouse gas emissions, there is a need for an optimization approach ... -
Attack-Aware Dynamic Upstream Bandwidth Assignment Scheme for Passive Optical Network
(Walter de Gruyter GmbH, 2023)Network security is an important component of today’s networks to combat the security attacks. The passive optical network (PON) works at the medium access layer (MAC). A distributed denial of service (DDOS) attack may be ... -
Effect of Nano-SiO2 on Strength and Hydration Characteristics of Ternary Cementitious Systems
(Institute for Ionics, 2023)This paper shows results of laboratory study on the effects of nano-SiO2 on Portland cement-fly ash systems. It is aimed to improve performance of fly ash–cement systems, particularly at early age, with the inclusion of ... -
Effects of extrusion cooking on the nutritional quality of puffed snacks made from blends of barley and green lentil flours
(SPRINGER, 2023)Increasing demand for nutritionally dense foods warrants the investigation of high fber and protein ingredients in snack food applications. In this study, blends of barley (22.9% dietary fber, db) and green lentil (26.4% ... -
Crown shaped edge multiband antenna design for 5G and X-Band applications
(SPRINGER, 2023)Nowadays we are experiencing the fifth-generation (5G) technology with new frequency bands to achieve high broadband speed, minimum latency and more developed end user devices. Due to the different frequency ranges for ... -
Introducing a spatially explicit Gini measure for spatial segregation
(SPRINGER, 2023)This paper proposes an alternative measure of economic segregation by income that utilizes the Gini index as the basis of measurement. The Gini Index of Spatial Segregation (GSS) is a ratio of two Gini indices that compares ... -
Improvement of an Undisturbed Peat Soil with Jet Grout Columns: Physical and Numerical Modeling
(Institute for Ionics, 2023)The bearing capacity of the composite-formed soil, such as grouted peat soil, is a crucial design parameter that can be improved by employing jet grout columns (JGCs). The coupling effect of the requirement of new industrial ... -
Can mesenchymal stem/stromal cells and their secretomes combat bacterial persisters?
(SPRINGER, 2023)The increasing number of life-threatening infections caused by persister bacteria is associated with various issues, including antimicrobial resistance and biofilm formation. Infections due to persister cells are often ... -
Investor bias, risk and price volatility
(Emerald Publishing, 2023)Purpose: This study proposes a framework based on salience theory and shows that focusing on one type of risk (idiosyncratic or systemic) can explain overpricing of securities ex ante, and resales at low prices during ... -
Investigating the Tradeoff Between the MMF Distortion and End Turn Length of a 2-Pole Line Start SynRM Performance
(Institute for Ionics, 2023)Conventional 2-pole AC machine windings have long end windings and generate harmonics, which increase losses and reduce torque density. This study investigates the performance tradeoff between the level of distortion (THD) ... -
Multi-focus image fusion by using swarm and physics based metaheuristic algorithms: a comparative study with archimedes, atomic orbital search, equilibrium, particle swarm, artificial bee colony and jellyfish search optimizers
(SPRINGER, 2023)The lenses focus only on the objects at a specific distance when an image is captured, the objects at other distances look blurred. This is referred to as the limited depth of field problem, and several attempts exist to ... -
Magnetic Separation of Micro Beads and Cells on a Paper-Based Lateral Flow System
(GAZİ ÜNİVERSİTESİ, 2023)Paper based lateral flow systems are widely used biosensor platforms to detect biomolecules in a liquid sample. Proteins, bacteria, oligonucleotides, and nanoparticles were investigated in the literature. In this work ... -
Estimation of cohesion for intact rock materials using regression and soft computing analyses
(Institute of Physics, 2024)Shear strength parameters such as cohesion (c) and internal friction angle (.) are among the most critical rock properties used in the geotechnical design of most engineering projects. However, the determination of these ... -
Data-driven discovery and DFT modeling of Fe4H on the atomistic level
(ELSEVIER, 2024)Since their discovery, iron and hydrogen have been two of the most interesting elements in scientific research, with a variety of known and postulated compounds and applications. Of special interest in materials engineering ... -
Rational design of EDTA-incorporated nanoflowers as novel and effective endodontic disinfection against biofilms
(SPRINGER, 2024)The ethylenediaminetetradiacetic acid (EDTA) is one of the most commonly used irrigation solutions. Although EDTA has a very low antimicrobial property, it is used to remove inorganic part of smear layer in areas of root ... -
