This paper aimed to materialize how to teach forecasting and predictions to undergraduate students.There are two modes of thinking, including the determination of forecasters and forecast errors. To determine thebest forecast, we have to use the methodology of minimizing sums of forecast errors, which is further discussed inthis paper. An example of this is single exponential smoothing, which is rather difficult when it comes to determiningthe smoothing constant alpha. In management and administrative situations, the need for planning is great becausethe lead time for decision-making ranges from several years to a few days or even a few hours. The ability to predictmany types of events seems, as natural today as, to be the accurate forecasting of weather conditions in a fewdecades.

Diffusion of light in turbid media with internal reflections
Authors: Schirmacher W. , Ruocco G.
Published: July 2023

We relate the the Kubelka-Munk equations for the description of the intensity transfer of light in turbid media to a one-dimensional diffusion equation, which is obtained by averaging the three-dimensional diffusion equation over the lateral directions. This enables us to identify uniquely the Kubelka-Munk parameters and derive expressions for diffuse reflection and transmission coefficients including the effect of internal reflections. Without internal reflections we recover the Kubelka-Munk formulae for these coefficients. We show that the Kubelka-Munk equations are the proper radiative-transfer equations for the one-dimensional diffusion problem.
How should a small country respond to climate change?
Authors: Haymet A. D. J.
Published: July 2023

Responses to the global climate crisis often focus on the largest current emitters of greenhouse gases. However, analysis shows that about a third of emissions come from a collection of small emitters, each contributing one- to two-percent of the total additional CO2 injected into the communal atmosphere. Attempts to hold global warming to less than 1.5℃ cannot succeed without also reducing emissions from these small countries.

Political Fandom and Social Media Code of Ethics
Authors:   Center for Civic Politics Research, Yoo Sung-jin
Published: July 2023

This article examines the institutional efforts centered on political parties to offset the negative effects of political fandom that are frequently discussed in the current society. Based on overseas cases, it proposes ‘social media code of ethics’ for political parties in Korea as a way to reduce the negative effects of digital democracy. The Netherlands have already set up an agreement between political parties and online platform users according to IDEA's recommendation, and British political parties are making efforts to prevent the side effects of affective polarization by including social media-related policies in their own rules. Unlike the situation in other countries, there is no content to reduce the political harm of social media in our party constitution, party rules, and ethics regulations. The code of ethics proposed in this article consists of active opposition to hate speech and reckless digital attacks by individual political parties, compliance with responsible digital ethics, and voluntary disciplinary action and punishment in case of non-compliance. The code of ethics, declared in the form of an agreement between political parties, can be a starting point for political parties and politicians to adapt with a responsible attitude in the new change of daily life in political fandom.

Published: July 2023

Soot particles are one of the main causes of today's pollution because of their negative contribution to global warming and human health. Aviation is one of the domains dealing with soot reduction as the new engine concepts are developed to reduce fuel consumption and global emissions. Despite the fact that most combustion devices used for air transportation operate at high pressure (e.g., aircraft gas turbines up to 40 bar), our understanding of soot formation and oxidation in such conditions is not yet at an appropriate level, as there is still a fundamental lack of experimental data and corresponding predictive models in the literature. Thus, the objective of the current study is to evaluate soot formation and oxidation processes in stratified, swirled, premixed ethylene/air flames examined with a variety of laser diagnostics designed to simultaneously measure soot particle and soot precursor 2D-distributions, as well as the flame structure and the aerodynamic field. For that, the SIRIUS burner was selected because of its ability to produce flames with topologies similar to those encountered in aircraft combustors. Soot particle distributions are measured by Planar Laser-induced incandescence (PLII) diagnostic. The flame structure is obtained by detecting the hydroxyl radicals (OH) with Planar laser-induced fluorescence (PLIF). A second PLIF diagnostic is also used to investigate the production of polycyclic aromatic hydrocarbons (PAH) with the detection of two benzene rings molecules which are recognized as good precursors of soot nucleation and growth. Finally, the particle Image Velocimetry (PIV) diagnostic is used for measuring the velocity distributions. These laser diagnostics are coupled together in order to obtain cross-correlations between several scalar parameters playing a determining role in the soot formation/consumption processes. The experimental results collected at atmospheric pressure are reviewed and critically assessed. A scenario describing the link between the soot inception, growth, aggregation and oxidation processes is proposed by analyzing velocity, OH, PAHs and soot distributions. In particular, the data reveal the presence of distinct regions for these processes. Incipient soot production zone is strongly function of specific local conditions of velocity, PAH concentration, and strain rate encountered at the interface of the internal recirculation zone and the fuel/air jet. The central part of the inner recirculation zone in which large structures move at low velocities provides suitable conditions for the aggregation of nascent soot particles while an oxidation region located in the upper zone of the internal recirculation zone favors the consumption of soot.
Soot Size Determination In A Swirl Stratified Premixed Ethylene-Air Flame By A Sampling Probe And Elastic Light Scattering

Published: July 2023

An experimental study was performed to measure the size and number density distributions of soot particles produced in turbulent, stratified (high spatial equivalence ratio gradient), swirled (rotating flow) premixed ethylene-air flames at atmospheric pressure. Soot particle size and number density measurements are initially performed using a Scanning Mobility Particle Sizer (SMPS). For this purpose, two-stage sampling and dilution device designed for hot gas analysis was used. The dilution rate of the sampling apparatus was evaluated to ensure a most representative probing. In a second step, the ex-situ measurements were replaced by single-shot measurements recorded with a high cadency planar multi-angle light scattering (2D-MALS) laser diagnostic technique, based on the relationship between aggregate size and light scattering angle. In a third step, results obtained by the SMPS as well as by the optical diagnostic were compared. Because a direct confrontation of the obtained results obtained is not feasible due to difference in nature of both techniques, a two-step post-processing methodology as developed. For this purpose, the median electric mobility diameters measured by SMPS were converted into diameters of gyration by means of a semi-empirical conversion tool. Moreover, a time average data processing was applied to the soot size distributions recorded by 2D-MALS, considering that SMPS measurements performed over a relatively large acquisition time converge to a single value. Results obtained in stratified swirled premixed flames by SMPS exhibit an overall good agreement with the optical measurements. This good similarity between the results provides a remarkably high degree of confidence in the quality of the measurements for both measurement systems investigated. Furthermore, the results suggest that a comparison of soot aggregate size and number density measurements between a sampling probe and a light scattering technique is still possible in turbulent flames at atmospheric pressure. While the current work has focused on the performances of SMPS and the 2D-MALS approach on a one-to-one basis, future work will also address the application of these diagnostics to high-pressure two-phase flames for which measurements are made in confined environments.
On The Relationship Between H2 Addition, Local Extinction And Hydrodynamic Instability In Non-Premixed Bluff-Body Stabilized Flames

In the race for decarbonization of the power sector, H2 is found to be a better candidate as it can be readily produced in large scales from renewables (e.g. wind and solar energy). Nevertheless, the difference in the thermophysical properties of H2 in comparison to the conventional fuels possesses additional operational challenges. For instance, although the high flame speed together with a wide flammability range offer improved flame stabilization, however, it intensifies the risk of flashback. Besides, the increased strain resistance due to H2 enrichment is expected to alter the flame shape significantly. Hence, it is apparent that the widespread implementation of H2 across various practical systems needs a thorough understanding of the various physical mechanisms. In this context, we examined the effect of hydrogen (H2) enrichment to methane (CH4) in a non-premixed bluff-body stabilized burner operating under typical central jet dominated flame mode. In the chosen mode of operation, globally, the flow field and flame feature three important successive spatial regions, namely, recirculation zone, neck zone and jet-like flame zone. In such configuration, the flame is exposed to a higher stretch rate in the neck zone and eventually undergoes local extinction. Such local extinction and subsequent re-ignition of broken flame branches have strong implications over the hydrodynamic instability of the coaxial annular air shear layer. It is well known that H2 addition increases the flame extinction strain rate and thus alters the local extinction phenomenon. To understand this phenomenon, we performed experiments at 10%, 20 %, 30% and 50 % hydrogen proportion in (H2-CH4) blend. High repetition rate (5 KHz) PIV and OH PLIF measurements are performed simultaneously to perceive the quantitative insights. The results obtained from POD and 1D wavelet transform indicated the suppression of vortex shedding at the annular air shear layer for H2 addition greater than 20 %, and thus quantified the beneficial effect of H2 addition in turbulent flame stabilization.
Experimental Study Of The Interaction Between A Turbulent Flame And A Cooling Air Film

Published: July 2023

The current experimental study is focused on the analysis of the interactions between a V-shaped lean turbulent premixed methane-air flame and a parietal cooling air film generated by means of a splash-cooling system. The flame structure, the reactive aerodynamics and the wall temperature are simultaneously studied by implementing planar laser-induced fluorescence of the OH radical (OH-PLIF), reactive particle image velocimetry (PIV) and surface intensity-ratio phosphor thermometry (PT). Results show that the mean flow field and the mean flame topology significantly differs according to the level of blowing ratio. Further joint correlations of experimental measurements highlight various FCAI regimes. For blowing ratios below unity, a common flame-wall interaction process occurs and the air film has a limited influence on the flame dynamics. Increasing the blowing ratio enables to establish a cooling air film at the wall. Though it effectively increases the level of thermal protection, it does not have much influence on the flame topology. Eventually, for larger blowing ratios, the flame dynamics is piloted by the shear layer dynamics, associated with strong flow strain. The flame is pushed away from the wall and is located in the outer region of the shear layer. The cooling effectiveness is not improved anymore and shows no more dependencies with the blowing ratio.

Published: July 2023

In development of Ventricular Assist Devices (VADs), Computational Fluid Dynamics (CFD) have arise as a powerful tool to gain insights on flow topologies within rotary blood pumps. Information regarding flow patterns and shear-stress distributions is of enormous importance, since flow induced blood damage as well as platelet activation is at-tributed to shear rates. Although methods for verification of numerical results are available, a lack of experimental validation is recognizable. To enable an experimental validation (i) hydraulic properties as well as flow patterns need to be preserved and (ii) a non-intrusive optical measurement technique needs to be capable of resolving flow topolo-gies appearing in rotary blood pumps. In this paper references to address (i) are provided and the focus is placed on (ii) by presenting a methodology to resolve flow topologies by usage of LDV Profile Sensor technology. This paper serves as a feasibility study and represents a preliminary stage towards actual optical measurements with rotary blood pumps. Therefore, a test bench with facilitated optical accessibility compared to Ventricular Assist Devices as well as operating conditions are introduced. Increased attention is dedicated to evaluation of measurement data by means of choosing a suitable procedure. Therefore, commonly used 2D-histograms for LDV raw data evaluation are compared to the method of Gaussian Kernel Density Estimation (Gaussian KDE). Subsequently, pre-processed raw data is further evaluated with a specially tailored Velocity Profile Validation Algorithm and determined circumferen-tial velocity profiles are discussed. In summary, herein presented feasibility study is deemed successful and LDV Pro-file Sensor technology is capable of resolving flow topologies within small gaps as they appear in Ventricular Assist Devices. Thus, LDV Profile Sensor technology may improve development of rotary blood pumps.
An Experimental Study Of Natural Gas Jet-Flames In Crossflow With High Hydrogen Admixture At Elevated Pressure Conditions
Authors: Boxx I. , Pareja J. , Saini P.
Published: July 2023

A series of high hydrogen-content jet flames in crossflow are investigated experimentally using high-speed (10 kHz) stereoscopic particle image velocimetry, dual-plane laser-induced fluorescence of the hydroxyl radical, and OH* chemiluminescence imaging. The flames were fueled with natural gas enriched to 70-, 80-, 90- and 100% H2, by volume at conditions approaching those found in the mixing duct of a modern gas turbine engine, specifically in close confinement, at 7 bars pressure and with a crossflow preheat of 511 K. The measurements indicate the recirculation zone on the leeward side of the jet plays a critical role in stabilization of the lifted jet flame in crossflow. The measurements show that local heat-release from a flame in this region acts as a self-reinforcing feedback mechanism, strengthening the recirculation zone and increasing local residence time there. This, in turn, creates conditions more favorable to flame stabilization. The measurements also showed how close confinement of the JICF by the flow channel walls affects jet-penetration and growth of the counter-rotating vortex pair.
Influence of Lubricant Addition on Heat Exchange Regimes During Spray Cooling

Published: July 2023

Spray cooling is used in a variety of industries, including metallurgy, electronics, and medicine. Ease of spray generation, as well as the ability to cool relatively large surfaces or precise regions of interest, are among the key assets. Spray cooling can provide a relatively high heat flux, especially if it is accompanied by liquid evaporation. Additionally, it can be applied not only as a coolant but also as a transport medium for lubricating fluid in specific applications, such as hot die forging. Typically, the working fluid is a multi-component mixture with improved cooling and lubricating properties. Once the bulk liquid evaporates, particles or dissolved lubricant can settle on the hot solid substrate. Existence of components with various physico-chemical properties on the surface (binders, surfactants, dispersed particles, etc.) can significantly affect the spray impact, as well as the outcome of cooling regimes. Nevertheless, the accompanying thermal-hydraulic effects are still not well understood. An experimental facility for observing the impact of the multi-component spray, and characterizing heat transfer was designed for this study at the Institute for Fluid Mechanics and Aerodynamics. As a working fluid, varied mixtures of water and industrial white lubricant were used in different ratios. The visualization of spray impact and identification of the main hydrodynamic regimes were achieved using a high-speed video system. The inverse heat conduction problem was used to calculate the heat flux during continuous cooling from 445°C to 100°C taking into account temperature readings from within the substrate. Since the substrate was entirely insulated on all sides (except on the sprayed surface), the boundary conditions were well defined. The experimental data for pure water drops were compared with the results obtained using lubricating additives. It is discovered that even minimal volumes of lubricant augment the heat flux dramatically, particularly at rather high wall temperatures. The spray cooling process is accompanied by an extensive foaming near the wall and as a result, the Leidenfrost point is moved to a higher temperature, thus suppressing film boiling regime.
Hybrid Pulse-Burst / Cross-Correlation DGV For High-Speed Flow Measurements At 100 KHz
Authors: Burns R.A. , Fahringer T.W. , Danehy P.M.
Published: July 2023

Hybrid pulse-burst Doppler global velocimetry (PB-DGV)/pulse-burst, cross-correlation DGV (PB-CC-DGV) was demonstrated for the first time in the NASA Langley 4-foot Supersonic Unitary Plan Wind Tunnel, allowing simultaneous acquisition of mean and instantaneous high-repetition-rate velocity fields. The technique was used to make planar velocity measurements across an oblique shockwave generated by a large splitter plate set at a -2° angle of attack in a Mach 2.4 flow. Sequences of >100 consecutive instantaneous velocity images were obtained at a rate of 100 kHz. Velocity fields from both aspects of the hybrid measurement indicated errors less than 1-percent of anticipated velocities. Likewise, all assessments of measurement precision were approximately 1.6-percent of the local velocities. Additional demonstrations in different flowfields including a subsonic axi-symmetric jet and a supersonic Mars reentry vehicle model further illustrate the utility of the new hybrid method.
Tomographic Imaging Using Multi-Simultaneous Measurements (TIMes) For Single-Shot Emission Reconstructions In Turbulent Spray Flames
Authors: Martins F.J.W.A. , Foo C.T. , Unterberger A. , Mohri K.
Published: July 2023

Tomographic imaging using multi-simultaneous measurements of emissions is applied to three operating conditions of the SpraySyn burner in order to investigate the turbulent flame morphology and its potential impact on the flame spray pyrolysis. Instantaneous and time-averaged three-dimensional fields of CH* chemiluminescence (flame front marker) and atomic Na emission from NaCl dissolved in the injected liquid solution (linked to hot products of the spray flame) are reconstructed using 29 cameras divided between them. The association between CH* and Na signals is analyzed using isosurface visualizations, combined slices, profiles and scattered plots. The instantaneous results unveil the complex reacting turbulent flow and regions of interplay between the flame front and the hot spray products. The time-averaged results show that the investigated spray flames are slightly asymmetric near the burner exit and evolve towards symmetric bell-shaped distributions further downstream. In the context of flame spray pyrolysis, the flame asymmetries potentially lead to inhomogeneous characteristics of the final synthesized material.
Droplets Evaporation In Turbulent Flow: Statistical Study Based On Lagrangian Tracking And In Line Holography
Authors: Méès L. , Grosjean N. , Marié J.-L. , Fournier C.
Published: July 2023

Turbulence has long been suspected to increase the evaporation rate of droplets via the convective effects it generates. The experimental data reported in this paper provides evidence of this increase and statistically quantify these effects. Measurements was performed following a Lagrangian approach, using Digital in-line holography based on a high speed camera and an inverse problem reconstruction algorithm. Ether droplets was released in a quasi isotropic and homogeneous turbulence generated by synthetic jets. Their Schmidt number is typically of the order of 2 and their Reynolds number is moderate (≤ 3). Results are based on a large number of droplets trajectories for various turbulence conditions. The Lagrangian statistics computed from these trajectories, totaling 1.3 million samples, show that the relative mean motion and turbulence seen by the droplets on average increases their evaporation rate. Within the parameter range investigated, this increase is not well predicted when estimating the convective effect in the Sherwood number with the norm of the instantaneous relative velocity seen by the droplets. In contrast, this increase is very well predicted when the Sherwood number is calculated using a Reynolds number based on the norm of the mean relative velocity plus its RMS fluctuation.
High-Speed Imaging And Temperature Measurements Of Microwave Enhanced Laser Induced Plasma
Authors: Soriano J.K. , Ikeda Y.
Published: July 2023

Air plasma is typically generated by laser-induced breakdown using a focused high-energy laser beam. In microwaveenhanced laser-induced plasmas, the initial spark produced by laser-induced ablation of a nearby target may be utilized to generate air plasma by microwaves. Air plasma was therefore produced with and without a nearby target. Characterization of the air plasma was done by high speed-imaging and time-series emission spectral measurements. The evolution of the plasma temperature was measured by SPECAIR simulations of the OH and N2+ positive systems. The microwave-enhanced plasma exhibit unequal values for the vibrational and rotational temperatures indicating a nonequilibrium state of the air plasma. The estimated temperatures of vibrational temperatures were considered lower estimates of the electron temperature and rotational temperatures as higher estimates of the gas temperature. The increase in vibrational temperatures of the air plasma with and without the target both indicated the heating of the electrons due to the addition of microwaves. However, the constant value of the rotational temperature for both cases indicated that the gas temperature is not affected by the microwave.

Published: July 2023

Wine coffee is a type of coffee that comes from a post-harvest process that is processed through a fermentation process to produce a unique taste resembling the aroma of wine.  Therefore, wine coffee is also often referred to as fermented coffee and the aroma in coffee wine is produced by the overhauling of compounds due to the metabolism of microorganisms in the fermentation process.  However, the strong aroma and taste of coffee wine does not diminish the original taste of coffee.  The purpose of this study was to determine the organoleptic and physical tests of wine coffee from SUMBAWA tepal coffee.  This research was conducted for 3 months.  The changes observed in this study were organoleptic tests, color physical tests, and pH.  From the organoleptic test results, color, taste, and aroma were more dominant on the somewhat liking scale and the strong scale on the level of liking (hedonic) and acceptance (scoring).  Whereas on the physical test, the color brightness (L *) shows a bright color indication, because it is above the 50 step. And the pH is on the acid scale.

The purpose of this study was to determine the effect of adding agar powder as a thickener to the physical, chemical, and sensory characteristics of papaya dodol and to determine the water content, vitamin C, and organoleptic content of papaya dodol by adding agar powder as a thickener to the physical, chemical characteristics, and sensory lunkhead papaya. The research method used was a completely randomized design (CRD) with three replications with the addition of agar powder, namely control without the addition of 0% P1 agar powder, 3% P2 agar powder, 5% P3 agar powder and 7% P4 agar powder. In this study the parameters observed were water content, vitamin C, and organoleptic properties of papaya dodol with the addition of agar powder as a thickener to the physical, chemical, and sensory characteristics of papaya dodol. The addition of agar powder in the manufacture of papaya dodol increases the water content in the product. In addition, agar powder can also protect vitamin C during the processing, although it still suffers damage when heated. The use of agar powder also gives a significantly different chewy texture to papaya dodol. However, the agar powder did not have a significant effect on the color, aroma, and taste of the papaya dodol, because the papaya dodol aroma was stronger and more dominant, while the agar powder had no taste and its gelatinous nature did not affect the change in the taste of the papaya dodol.

Mathematical Modeling Through the Eyes of Elementary and Middle Preservice Teachers

Published: July 2023

Mathematical modeling is a useful pedagogy in mathematics education, but preservice teachers (PSTs) conceptualization of the teaching and learning of modeling practices is an ongoing concern. This research study examined 31 elementary and middle grades PSTs’ conceptualization of mathematical modeling and their experiences with such modeling. The study participants were recruited from two, four-year university mathematics methods courses located in northeastern and midwestern United States. Data for this study was collected through a questionnaire and analyzed using qualitative and quantitative methods. Results indicated that most of the PSTs had little understanding of the intersection of mathematical modeling, and the teaching and learning of mathematics. As such, many perceived mathematical modeling as an exclusive action reserved for teachers. Additionally, the results revealed that most participants had minimal, if any, experience with mathematical modeling. These limited experiences portrayed mathematical modeling as a show and tell method or step-by-step explanation. Our results expand the inadequate research into elementary and middle grades PSTs’ knowledge of and experiences in mathematical modeling and warrant the exigency for the inclusion of extensive mathematical modeling practices into methods and content courses for PSTs. The directions for future research and implications for researchers and teacher education programs are also discussed.
