An investigation into the optothermal behavior of a high power red light emitting diode: impact of an optical path
Monochromatic light emitting diodes (LEDs) are getting more attention day by day for a very wide range of applications such as general lighting, signage, automotive lighting, display, water purification, and skin imaging. ... -
An investigation into thermal and optical performance of multi-purpose LED automotive exterior lighting systems
(2015-12)Vehicle lighting is important for both security and comfort. In addition, external lighting standards need to be reliable and are subject to international norms for the prevention of accidents. For this reason, automobile ... -
Investigation of average crosslink distance and physicochemical properties of gummy candy during storage: Effect of formulation and storage temperature featured
(AIP Publishing, 2023-05)Texture is linked to food structure at micro- and macro-levels. The most effective way to manipulate gel texture is to change the number of crosslinks per unit volume. Polymer concentration and type can be changed or the ... -
Investigation of combined optical and thermal effects on phosphor converted light-emitting diodes with liquid immersion cooling
(SPIE, 2018)The inclusion of phosphor into a high brightness light-emitting diode (LED) package is a complicated task since LEDs are encapsulated with a phosphor and epoxy mixture to convert blue photons to white light. Moreover, this ... -
Investigation of corrosion behavior of carbon steel for petroleum pipeline applications under turbulent flow conditions
(Institute of Information Science, 2020)This study investigates the corrosion of steel samples immersed in water with a dynamic corrosion setup at different pH values for three different velocities and three different exposure time. The characteristics of material ... -
Investigation of corrosion in oil pipelines through surface nano-treatment
(2020-01)Corrosion is the unintentional and degradation of a material caused by the reaction of that material with its environment and a natural possible hazard correlated with gas and oil generation and transportation facilities. ... -
An investigation of critical success factors for green retrofitting of existing healthcare buildings
(2020-01-17)The fundamental principle of health care practice is ‘first do no harm,’ but ironically, the activities of healthcare itself consume critical pollution, and, consequently, indirect adverse effects on public health. Concerted ... -
Investigation of flame characteristics in a turbulent premixed combustion
(2018-10)In this thesis, the turbulent flame closure (TFC) model and coherent flame model (CFM) of turbulent premixed flames as steady state flow are used. In addition, large eddy simulation (LES) model as unsteady state flow is ... -
An investigation of makerspaces for their contribution to social innovation
Makerspaces are workshop areas or programs where communities or/ individuals collaborate together, share knowledge in an open source way, and produce products fast with an easy access to fabrication tools. According to my ... -
An investigation of occupant energy-saving behavior in vernacular houses of behramkale (Assos)
(MDPI, 2021-12-06)Despite its well-known potential to reduce energy use, the inquiry of whether vernacular architecture prompts its occupants to have energy-saving behavior has been neglected. This paper aims to investigate the influence ... -
Investigation of P-wave scalar and S-wave pseudo-scalar charmonia semileptonic transitions to the Ds(D) meson in QCD
(IOP Publishing, 2010)In this work, the semileptonic decays of the scalar charmonium state Xc0 and the pseudo scalar charmonia states ηc(1s) and ηc(2s) into Ds and D mesons are analyzed. The form factors of the transitions Xc0 → Ds(D)_ν and ... -
Investigation of pair distribution function method on structural analysis of nanocrystalline powders
(Int Union Crystallography, 2022-08)N/A -
Investigation of pair distribution function method on structural analysis of x-ray diffraction data from nanocrystalline powders
Pair Distribution Function analysis is a local characterization method gaining momentum recently. Conventional X-ray diffraction and Rietveld methods have proven not to be accurate in the case of analysis of diffraction ... -
An investigation of performance of synthetic jets emanating from circular, elliptical and rectangular nozzles
(IEEE, 2018-07-24)Impinging synthetic jets have been considered as a future solution for cooling miniature structures. Synthetic jet performance is sensitive to a number of parameters such as orifice size, orifice shape and nozzle-to-target ... -
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 stochastic pairs trading strategies under different volatility regimes
(Blackwell, 2010-09)We investigate several market-neutral trading strategies and find empirical evidence that market-neutral equity trading outperforms in 2008, the first full year of the global financial meltdown. In our experiments we use ... -
Investigation of the change of the shopping mall's space organization in Istanbul
(Taylor & Francis Group, 2014)Within the scope of this article shopping malls were discussed as a building type and the evolution of a building type was tried to be witnessed within a twenty-five year period by comparing the early and late examples of ... -
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 ... -
An investigation of the effects of surface topography on the seismic structural demands for a region of istanbul
(CRC Press, 2019)In this study, we provide preliminary results from an ongoing study—funded by The Scientific and Technological Research Council of Turkey, TUBITAK—investigating the effects of site-specific surface topography and soil ...
