Abstract The Soleris Non-fermenting Total Viable Count method was previously validated for a wide variety of food products, including cocoa powder. A matrix extension study was conducted to validate themethod for use with cocoa butter and cocoa liquor. Test samples included naturally contaminated cocoa liquor and cocoa butter inoculated with natural microbial flora derived from cocoa liquor. A probability of detection statistical model was used to compare Soleris results at multiple test thresholds (dilutions) with aerobic plate counts determined using the AOAC Official Method966.23 dilution plating method. Results of the two methods were not statistically different at any dilution level in any of thethree trials conducted. The Soleris method offersthe advantage of results within 24 h, compared tothe 48 h required by standard dilution plating methods.

Abstract:
ABSTRACT This paper investigates the potential of using a frequency response mode to reduce the dilution effect of non-diagnostic evidence on auditors' fraud risk judgments. In two experiments, we test one hypothesis and examine a research question related to the dilution effect where response mode (frequency versus probability) and type of non-diagnostic or irrelevant information are manipulated between-participants. Results of the hypothesis tests show that auditors' fraud risk judgments demonstrate a significantly lower dilution effect when they evaluate diagnostic and non-diagnostic or irrelevant evidence using a frequency response mode, as compared to the probability response mode; this effect is most pronounced when auditors are provided with favorable non-diagnostic or irrelevant evidence.

Abstract:
On considere la modelisation de la combustion turbulente des melanges pauvres a richesse variable, en particulier le cas d'un melange reactif dilue par l'air ambiant. Les bases d'une description thermochimique du melange instantane sont posees. Celle-ci est basee sur deux variables scalaires : une fraction de melange f liee a la richesse du melange frais local et une variable d'avancement c decrivant les reactions chimiques. Ces dernieres permettent d'exprimer la temperature et les fractions massiques des especes. A partir de l'analyse des etats des paquets de gaz frais et brules, une densite de probabilite jointe de c et f permettant de decrire l'etat thermochimique du melange reactif turbulent est proposee. Suivant l'hypothese d'un regime de flammelettes minces, la structure de cette pdf permet la description de la combustion d'un melange a richesse variable, prenant en compte en particulier l'extinction de flammelettes dans un melange dont la richesse est inferieure a la limite d'inflammabilite en regime pauvre. Cette pdf permet en outre de calculer le taux de production chimique moyen $$ : terme primordial dans la modelisation de la combustion turbulente de premelange. Une formulation de $$ tenant compte explicitement de la richesse locale du melange et de sa distribution statistique est proposee. Ce modele, associe a une fermeture des termes de transports turbulents par un modele k- est applique au cas d'une flamme stabilisee dans un ecoulement turbulent a point d'arret. Les resultats numeriques obtenus predisent en particulier une zone de reaction moyenne plane stabilisee entre le bruleur et la paroi conformement aux observations experimentales. Par ailleurs, les comparaisons sur l'axe de symetrie avec les resultats des theories 1d et les donnees experimentales permettent de quantifier l'effet de la dilution par l'air exterieur sur la structure de la flamme.

In analyzing the continuous culture system with feed cycling, if the time delay of microorganisms to adapt to their changing environment is neglected, the result is washout of the plasmid-bearing microorganisms whether the plasmid loss probability is considered as constant or variable. In our analysis, we take both the time delay in adaptation and variable plasmid loss probability into account, and the cycling in dilution rate being considered is in the form of rectangular wave. Results of numerical simulations are used to construct operating diagrams on the period-feed substrate concentration plane, showing the operating conditions under which both the plasmid-bearing and plasmid-free microorganisms will ultimately coexist. It is found that sufficiently large difference in delay times can result in coexistence, and larger coexistence regions are obtained for larger differences. Either larger maximum specific growth rate or smaller on-off time ratio will lead to larger coexistence regions. There exists an optimal maximum dilution rate which yields the largest coexistence region; washout of the plasmid-bearing microorganisms occurs when the maximum dilution rate is either too large or too small. The effects of the operating parameters period, feed substrate concentration, maximum dilution rate and on-off time ratio on the ultimate mass fraction of the plasmid-bearing microorganisms are also discussed.

Abstract:
An ecological community includes all individuals of all species that interact within a single patch or local area of habitat. Understanding the outcome of host–parasite interactions and predicting disease dynamics is particularly challenging at this biological scale because the different component species interact both directly and indirectly in complex ways. Current shifts in biodiversity due to global change, and its associated modifications to biological communities, will alter these interactions, including the probability of disease emergence, its dynamics over time, and its community-level consequences. Birds are integral component species of almost all natural communities. Due to their ubiquity and specific life history traits, they are defining actors in the ecology, evolution, and epidemiology of parasitic species. To better understand this role, this chapter examines the relative importance of birds and parasites in natural communities, revisiting basic notions in community ecology. The impact of changes in diversity for disease dynamics, including the debate surrounding dilution and amplification effects are specifically addressed. By considering the intrinsic complexities of natural communities, the importance of combining data from host and parasite communities to better understand how natural systems function over time and space is highlighted. The different elements in each section of the chapter are illustrated with brief, concrete examples from avian species, with a detailed example from marine bird communities in which Lyme disease bacteria circulate.

The group threshold is the concentration that is just perceived by 50% of the panel members. 4.2 Evaluation using the geometric mean The point of change is determined for every series of dilution eva­ luated. It is defined as the geometric mean of the dilution of the last negative and the first positive answer. The arithmetical mean and its standard deviation are calculated frcm the logarithms of the points of change. 4.3 Graphical evaluation The characteristic curve of the odor threshold is used. The rela­ tive cumulative frequency of positive answers is calculated for each odorant concentration and graphically plotted, while for odor concen­ tration a logarithmic scale is used. The odor threshold can be obtained frcm the resulting curve as the 50-percentile and so can the associated 16- and 84-percentiles. 4.4 Probit analysis If the odor sensitivity is normally distributed over the logarithm of the odor concentration, the characteristic curve of the odor threshold is a gaussian curve. This curve is converted into a straight line using the probit transformation. The analyses can be carried out graphically on probability paper or by transformation of the relative cumulative fre­ quency by using a table function and calculating the regression lines.

Abstract:
With the ever rising concern of global warming, carbon capture is gaining the reputation of one of the most challenging fields of research. A very promising technology to capture CO2 is oxy-combustion. Oxy-combustion offers several advantages over conventional combustion technologies, such as flue gas volume reduction, high combustion efficiency, low fuel consumption and significant reduction in NOx emissions. Liquid fuel is available and it is the most widely used source of energy in the world. Easy handling and transportation, less storage volume and higher flame temperature are some of the features of liquid fuel which give it an upper hand over other sources. In this study, an experimental work on oxygen enriched combustion of ethanol in a vertical reactor by Lacas F. et. al. has been modeled numerically. Non-premixed model using Probability Density Function has been incorporated to simulate the combustion process of ethanol droplets. Predicted combustion characteristics are found to be in good compliance with the experimental data. In addition to this, effects of dilution of carbon-dioxide in oxygen on the flame properties have also been presented. Combustion of ethanol in oxygen-carbon dioxide environment has been compared with that of the conventional air environment.

Abstract:
The film cooling flow field is the result of a highly complex interaction between the film cooling jets and the mainstream, Understanding this interaction is important in order to explain the physical mechanisms involved in the rapid decrease of effectiveness which occurs close to the hole exit. Not surprisingly, it is this region which is not modeled satisfactorily with current film cooling models. This study uses a high frequency response temperature sensor which provides new information about the film cooling flow in terms of actual turbulence levels and probability density functions of the thermal field. Mean and rms temperature results are presented for 35° round holes at a momentum flux ratio of I = 0.16, at a density ratio of DR = 1.05. Probability density functions of the temperature indicate penetration of the mainstream into the coolant core, and ejection of coolant into the mainstream. Extreme excursions in the fluctuating temperature measurements suggests existence of strong intermittent flow structures responsible for dilution and dispersion of the coolant jets.

Abstract:
In the present paper, the flames from DJHC burner, imitating MILD (Moderate and Intense Low Oxygen Dilution) combustion, are simulated using PDF transport modeling. Two different solution approaches have been used to resolve the joint composition PDF. First, a Lagrangian approach is used to solve the joint composition PDF, while in the second approach, the approximate solution is achieved by using presumed shape PDF and DQMOM-IEM modeling known as Multi-Environment Eulerian PDF (MEPDF). A quantitative comparison of the predictions from these two solution methods has been performed for two different jet Reynolds number, i.e. Re = 4100 & 8800. Moreover, the effect of molecular diffusion is also explored by comparing the predictions using different micro-mixing models such as Coalescence Dispersion (CD), Euclidean Minimum Spanning Tree (EMST), and Interaction-by-Exchange-with-Mean (IEM) model. The obtained numerical predictions from both approaches are compared with the experimental data to highlight the accuracy as well as the predictive capability of these models. In the case of low Reynolds number (Re = 4100), it is observed that the mean axial velocity and turbulent kinetic energy profiles are in good agreement with the measurements while the temperature profiles are slightly over-predicted in the downstream region. Although MEPDF results are in good agreement with the LPDF results, both the model predictions tend to exhibit discrepancies at higher Reynolds number.

Abstract:
Abstract We present the design, fabrication, and characterization of a micromixer that uses an electrokinetic instability (EKI) as the stirring mechanism. We have observed that microchannel liquid flows subjected to sinusoidally alternating electric fields exhibit, under certain electric field strengths and geometries, a flow instability capable of rapidly stirring micro- and nanoliter volume solutions [1]. We have performed a fluorescein dilution experiment to observe the rapid dispersion of dyed and undyed buffers within the mixing chamber as a result of EKI stirring. The flow field was imaged using an inverted, epifluorescent microscope fitted with a 12 bit, cooled CCD camera. We have initially characterized the mixer performance by computing ensemble-averaged probability density functions (PDF’s) and power spectra of the instantaneous, spatial fluorescence intensity fields. This novel stirring mechanism has the potential for significantly improving the functionality of microfluidic, bioanalytical devices.

Full text
Abstract:
This paper describes experimental measurements of forced ignition of prevaporized liquid fuels in a well-controlled facility that incorporates non-uniform flow conditions similar to those of gas turbine engine combustors. The goal here is to elucidate the processes by which the initially unfueled kernel evolves into a self-sustained flame. Three fuels are examined: a conventional Jet-A and two synthesized fuels that are used to explore fuel composition effects. A commercial, high-energy recessed cavity discharge igniter located at the test section wall ejects kernels at 15 Hz into a preheated, striated crossflow. Next to the igniter wall is an unfueled air flow; above this is a premixed, prevaporized, fuel-air flow, with a matched velocity and an equivalence ratio near 0.75. The fuels are prevaporized in order to isolate chemical effects. Differences in early ignition kernel development are explored using three, synchronized, high-speed imaging diagnostics: schlieren, emission/chemiluminescence, and OH planar laser-induced fluorescence (PLIF). The schlieren images reveal rapid entrainment of crossflow fluid into the kernel. The PLIF and emission images suggest chemical reactions between the hot kernel and the entrained fuel-air mixture start within tens of microseconds after the kernel begins entraining fuel, with some heat release possibly occurring. Initially, dilution cooling of the kernel appears to outweigh whatever heat release occurs; so whether the kernel leads to successful ignition or not, the reaction rate and the spatial extent of the reacting region decrease significantly with time. During a successful ignition event, small regions of the reacting kernel survive this dilution and are able to transition into a self-sustained flame after ∼1–2 ms. The low aromatic/low cetane number fuel, which also has the lowest ignition probability, takes much longer for the reaction zone to grow after the initial decay. The high aromatic, more easily ignited fuel, shows the largest reaction region at early times.

Abstract:
In this paper, Markov chain Monte Carlo(MCMC) inversion method based on the Bayesian inference is used to invert parameters of leak source in two-dimensional space. Sensors are divided into three groups with different arrangements: linear-array perpendicular to the wind direction, linear-array parallel to the wind direction and cross-array. Then the source probability distributions of different arrangements and quantities on the accuracy and efficiency were analyzed and compared. It is shown that in one direction, more measurement information from different sensors result in more accurate inversion parameters. In the case with the same quantity of sensors, inversion parameters considering information of two directions are more accurate than which only considering one direction. It means that the combination of information in two directions can improve the inversion accuracy. The ventilation will enlarge the possible convergence region and increase the instability of inversion results in wind direction because of its migration and dilution effect. The inversion time consumed presents a positive relationship with the quantity of sensors. However, too much sensors may lead to the growth of consumption time, which are not conducive to practical application.

Full text
Abstract:
Abstract This study is an extension of the previous study, which presents the rotation effects of casing on syngas combustion. When syngas was applied to achieve the power output of proposed micro gas turbine, high temperature flame moves towards the exit of the combustor. Consequently, the temperature and temperature fluctuation at combustor exit increases. In this study, geometry of the can combustor is modified for the syngas application. In modified design, diameter of the fuel injector, length of the primary zone, configuration of primary and dilution holes is modified. To perform the numerical calculation, computational model which consists of three-dimension compressible k-ε realizable turbulent flow model and presumed probability density function for combustion process invoking a laminar flamelet assumption generated by detailed chemical kinetics from GRI 3.0 is used. Two typical composition of syngas are used namely: H2-rich (H2:CO = 80:20) and equal molar (H2:CO = 50:50). The combustion characteristics and NOx emissions were investigated to understand the rotating effects of syngas combustion in the modified design of the can combustor. In the modified design, the high-temperature flame gets stabilized along the wall of the combustor for both composition of syngas. Unlike in the previous design, the high-temperature flame moves towards the exit of the combustor. The exit temperature and pattern factor dropped and reached the design requirements after the modification. The rotation of casing enhances the swirling strength, which benefits proper mixing of fuel and air and leads to reduction in pattern factor and NOx emissions.

"Characteristics of Cycle-to-Cycle Combustion Variability at Partial-Burn Limited and Misfire Limited Spark Timing Under Highly Diluted Conditions."

Full text
Abstract:
Abstract Diluted combustion with exhaust gas recirculation (EGR) has been widely employed to improve the fuel economy of spark ignition engines. The combustion kinetics, however, are affected and the flame propagation speed is decreased. In order to compensate for this adverse effect, the spark timing needs to be recalibrated to achieve maximum brake torque (MBT). At high levels of EGR dilution, the spark timing is constrained by two ignition limits: 1) the partial-burn limit where the spark timing is retarded from MBT and 2) the misfire limit where the spark timing is too advanced. This work uses a probabilistic framework to capture the differences between both ignition limits. In particular, it introduces the concept of a nominal indicated mean effective pressure (IMEP) distribution based on the stochastic properties of the cycle-to-cycle variability (CCV) at nominal stable conditions. By defining a nominal band where fully burned cycles occur with high probability, we introduce a cycle classification method that can be used to 1) determine the level of randomness of misfire and partial-burn events, and 2) measure CCV. The new CCV metric based on the density of the nominal band is compared with the traditional coefficient of variation of IMEP (CoVIMEP). It is shown that the nominal band concept, together with the CoVIMEP, can help to discern between partial-burn limited and misfire limited conditions. Furthermore, the Kullback-Leibler divergence is used to demonstrate that the IMEP distribution is significantly different between nominal and partial-burn/misfire limited conditions. Experiments are carried at various EGR levels and spark timings while recoding in-cylinder pressure at steady state. Although the emphasis of this work is to characterize the differences of both ignition limits from a probabilistic point of view, similarities between partial-burn cycles at either limiting conditions are also discussed.

In ASME Turbo Expo 2016: Turbomachinery Technical Conference and Exposition. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/gt2016-56528.

Full text
Abstract:
The design and model simulation of a can combustor has been made for future syngas (mainly H2/CO mixtures) combustion application in a micro gas turbine. In previous modeling studies with methane as the fuel, the analysis indicated the design of the combustor is quite satisfactory for the 60-kW gas turbine; however, the cooling may be the primary concerns as several hot spots were found at the combustor exit. When the combustor is fueled with methane/syngas mixtures, the flames would be pushed to the sides of the combustor with the same fuel injection strategy. In order to sustain the power load, the exit temperature became too high for the turbine blades, which deteriorated the cooling issue of the compact combustor. Therefore, the designs of the fuel injection are modified, and film cooling is employed. Consequently, the simulation of the modified combustor is conducted by the commercial CFD software Fluent. The computational model consists of the three-dimensional, compressible k-ε model for turbulent flows and PPDF (Presumed Probability Density Function) model for combustion process between methane/syngas and air invoking a laminar flamelet assumption. The flamelet is generated by detailed chemical kinetics from GRI 3.0. Thermal and prompt NOx mechanisms are adopted to predict the NO formation. At the designed operation conditions, the modeling results show that the high temperature flames are stabilized in the center of the primary zone where a recirculation zone is generated for methane combustion. The average exit temperature of the modified can combustor is 1293 K, which is close to the target temperature of 1200 K. Besides, the exit temperatures exhibit a more uniform distribution by coupling film cooling, resulting in a low pattern factor of 0.22. The NO emission is also low with the increased number of the dilution holes. Comparing to the results for the previous combustor, where the chemical equilibrium was assumed for the combustion process, the flame temperatures are predicted lower with laminar flamelet model. The combination of laminar flamelet and detailed chemistry produced more reasonable simulation results. When methane/syngas fuels are applied, the high temperature flames could also be stabilized in the core region of the primary zone by radially injecting the fuel inward instead of outward through the multiple fuel injectors. The cooling issues are also resolved through altering the air holes and the film cooling. The combustion characteristics were then investigated and discussed for future application of methane/syngas fuels in the micro gas turbine. Although further experimental testing is still needed to employ the syngas fuels for the micro gas turbine, the model simulation paves an important step to understand the combustion performance and the satisfactory design of the combustor.
