Investigation of power distribution on an axial fan
(IEEE, 2016)Forced convection cooling systems utilize fans which can be axial or radial, small or large in many different configurations. Efficiency of a fan depends on its electrical and mechanical designs as well as the environmental ... -
Investigation of soot formation of ethylene/air jet diffusion flame with rank correlated slw including ethylene and acetylene radiation
(Begell House Inc., 2023)Radiation is significant, especially in sooting flames. The interaction between radiation and soot considerably affects the combustion regime. Spectral radiation models that account for the radiative effects of sooting ... -
Investigation of the effect of particle stability on the transport properties and thermal behavior of ethylene glycol-water/SiO2 binary nanofluids
(IOP Publishing, 2020-04-09)Nanofluids (Nfs) are considered as an effective working media in different thermal processes. Over the years, much attention has been paid to the problem of nanoparticle stability in base fluids in an unconfined area of ... -
Investigation of the refrigerator bottom cabinet cavity acoustic behavior
(2013-08)This thesis investigates the computational and experimental analysis for the acoustic behavior of a bottom cabinet cavity in a refrigerator. The finite element and analytical approaches are used in order to determine the ... -

(Elsevier, 2012-11)We are very pleased to inform the JQSRT readers and authors of several important recent developments about the Journal. First of all, according to the ISI Journal Citation Reports database, the 2011 Impact Factor for JQSRT ... -
Land subsidence susceptibility mapping using interferometric synthetic aperture radar (InSAR) and machine learning models in a semiarid region of iran
(MDPI, 2023-04)Most published studies identify groundwater extraction as the leading cause of land subsidence (LS). However, the causes of LS are not only attributable to groundwater extraction. Other land-use practices can also affect ... -
Learning medical suturing primitives for autonomous suturing
(IEEE, 2021)This paper focuses on a learning from demonstration approach for autonomous medical suturing. A conditional neural network is used to learn and generate suturing primitives trajectories which were conditioned on desired ... -
Learning to exploit passive compliance for energy-efficient gait generation on a compliant humanoid
(Springer Nature, 2019-01)Modern humanoid robots include not only active compliance but also passive compliance. Apart from improved safety and dependability, availability of passive elements, such as springs, opens up new possibilities for improving ... -
Local density of electromagnetic states within a nanometric gap formed between two thin films supporting surface phonon polaritons
(AIP Publishing, 2010)We present a detailed physical analysis of the near-field thermal radiation spectrum emitted by a silicon carbide (SiC) film when another nonemitting SiC layer is brought in close proximity. This is accomplished via the ... -
Localized near-field radiative heat transfer in biomimicry designs inspired by neon tetra fish
(Begell House Inc., 2019-06)Inspired by multilayer structure of the Neon tetra tropical fish which is one of the most fascinating multilayer systems ever reported in nature, we investigate the localized effects of coupling of surface phonon polaritons ... -
Localized radiative energy transfer from a plasmonic bow-tie nano-antenna to a magnetic thin film stack
(Springer Business+Media, 2011-06)Localized radiative energy transfer from a near-field emitter to a magnetic thin film structure is investigated. A magnetic thin film stack is placed in the near-field of the plasmonic nano-antenna to utilize the evanescent ... -
Low-cycle fatigue behavior of friction stir-welded copper joints
(Springer, 2021-11)Investigation of the fatigue response of friction stir-welded (FSWed) joints is especially important in the design and manufacturing of components with exposure to cyclic loading. In this study, cyclic response of FSWed ... -
Low-loss optical switch using Brewster angle
(IEEE, 2011)Fabrication and actuation errors of submicron silicon waveguide optical switches are reported to remain within sub-100 nm ranges. These errors cause high loss ruining the optical performance of the switches at the on-state. ... -
Lower uncertainty bounds of diffraction-based nanoparticle sizes
(Wiley, 2022-06)A self-consistent analysis is reported of traditional diffraction-based particle size determination techniques applied to synthetic diffraction profiles generated with the Patterson approach. The results show that dimensions ... -
Machine learning to predict junction temperature based on optical characteristics in solid-state lighting devices: A test on WLEDs
(MDPI, 2022-08)While junction temperature control is an indispensable part of having reliable solid-state lighting, there is no direct method to measure its quantity. Among various methods, temperature-sensitive optical parameter-based ... -
Manufacturing and mechanical behavior of titanium-steel composite by accumulative roll bonding
(Trans Tech Publications Ltd, 2021)Metal matrix composites have attracted interest for use in several engineering applications and this study focuses on the fabrication titanium and interstitial free steel composite and its mechanical performance. Accumulative ... -
