Analyzing the Commercial Air Travel Experience for Passengers with Disabilities
Creators: name: Major, Wesley L.
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Air transportation and freight services

description: Airlines are legally required to provide adequate service to passengers with disabilities; this research examines the quality of service provided based on the analysis of airline complaint data and the results of a survey of passengers with disabilities. The provision of adequate service to airline passengers is challenging since passenger counts continue to rise and passengers are increasingly diverse. Airline passengers with disabilities are protected by federal legislation under the Air Carrier Access Act (ACAA), 49 U.S. Code § 41705, which prohibits discriminatory treatment of people with disabilities in air transportation. Regulations outlined in 14 CFR Part 382, Nondiscrimination on the Basis of Disability in Air Travel, require that airlines and airports are accessible, and require that airline, airport and contract personnel provide appropriate accommodations and services to people with disabilities.
To track operational efficiency and compliance with the ACAA, the Department of Transportation collects data on airline performance. Data are published in monthly and annual reports. One component of these reports is complaint data. Complaints are an important metric because they identify deficiencies in service.
Individual complaints are forwarded to airport and airline service providers for investigation; however, complaint data do not appear to be used to systematically assess the adequacy of service, as evidenced by a disproportionately high and rising number of disability complaints.
The objective of this research is to investigate the provision of air service for passengers with disabilities. This investigation includes identification of the regulations that affect commercial air travel for passengers with disabilities, an examination of disability-related complaints, specifically the number and rate of these complaints compared to complaints for all travelers, and an assessment of service based on a survey of passengers with disabilities.

Year: 2020

description: E-mails present an interpersonal computer-mediated communication and a most-widely used form of digital communication. In the formal academic setting, digital interaction between students and professors, although used on daily bases, frequently requires students to deliver higher pragmatic competence and language awareness to reflect power asymmetry. However, it also provides an opportunity for lowering the power distance settings, and for the utilization of engagement markers in order to establish and maintain a more accommodating and beneficent environment. As the markers involving the reader into the context, engagement markers explicitly build the relationship between the students and their professors. Using both qualitative and quantitative analysis, the paper will demonstrate how the use of engagement markers as a distinct metadiscourse category in student-professor e-mail communication facilitates interaction and establishes a more trusting relationship. Using the corpus of student e-mails to professors, in both Serbian and English, the analysis will focus on the lexical elements (second person pronouns, imperatives, question forms, etc.) that explicitly address professor as the participant in the e-mail content, thus creating a more amiable context and a low power distance setting. The results will demonstrate the differences in the use of engagement markers in English with the distinct formal communication and in Serbian with less lexical formal engagement markers. Finally, the results will reveal the distinctive use of metadiscourse markers in digital environment and the informal tendencies that are gradually prevailing over the formal communication.

description: Background: We investigated the associations between education and leisure-time, occupational, sedentary and total physical-activity levels based on data from the German National Health Interview and Examination Survey 1998 (GNHIES98). The roles of income level, occupational status and other mediating variables for these associations were also examined. Methods: The total study sample of the GNHIES98 comprised 7,124 participants between the ages of 18 and 79. Complete information was available for 6,800 persons on leisure-time, sedentary and total physical-activity outcomes and for 3,809 persons in regular employment on occupational activity outcomes. The associations between educational level and physical activity (occupational, sedentary, leisure-time and total physical activity) were analysed separately for men and women using multivariate logistic regression analysis. Odds ratios (OR) of educational level on physical-activity outcomes were calculated and adjusted for age, region, occupation, income and other mediating variables. Results: After adjusting for age and region, a higher education level was associated with more leisure-time activity – with an OR of 1.6 (95% CI, 1.3-2.0) for men with secondary education and 2.1 (1.7-2.7) for men with tertiary education compared to men with primary education. The corresponding ORs for women were 1.3 (1.1-1.6) and 1.7 (1.2-2.4), respectively. Higher education was associated with a lower level of vigorous work activity: an OR of 6.9 (4.6-10.3) for men with secondary education and 18.6 (12.0-27.3) for men with primary education compared to men with tertiary education. The corresponding ORs for women were 2.8 (2.0-4.0) and 5.8 (4.0-8.5), respectively. Higher education was also associated with a lower level of total activity: an OR of 2.9 (2.2-3.8) for men with secondary education and 4.3 (3.3-5.6) for men with tertiary education compared to men with primary education. The corresponding ORs for women were 1.6 (1.2-2.0) and 1.6 (1.2-2.1), respectively. Conclusions: In Germany adults with a lower level of education are more physically active, both at work and overall, compared to adults with a higher education level, although they are less physically active in their leisure time. Higher work-related activity levels among adults with lower education may explain why they are less active in their leisure time.
The Garip (Strange) Movement: A Poetic Return to "Naturality" or a Deep Ecological Reappraisal of "Nature"?

subject: Turkish literature
subject: Philosophy of nature

description: In 1941, Orhan Veli Kanik, Melih Cevdet Anday, and Oktay Rifat Horozcu, published a poetic manifesto, called Garip (or Strange), that heralded a new period in modern Turkish poetry, known as "The Garip Movement." In the manifesto, Kanik, Anday, and Rifat declared a total aesthetic break from the conventions of the classical Ottoman poetry, and challenged its formalistic rules such as rigid prosodic structure, syllabic meter, and rhythmic pattern. Instead, they introduce a new conception of poetry which is purified from rhetorical language, elaborated diction, and formalistic patterns, and which is entirely based on free verse. Integrating their distinctively socialist perspective with their poetry, these rebellious poets reject the aesthetical movement that reinforces strict boundaries between the artist and the audience, and they insist that poetry must be written about and for the common man with a colloquial language that mirrors up the immediacy and naturality of everyday world. While the Garip poets specifically reveal the complexity of human relationships with their environment using a particular local area – generally Istanbul and its neighbourhood – as their setting, within a universal panorama of their themes, they also emphasize how human beings as a species are involved in a web of connections with other living and non-living beings in their habitat. Kanık, Rifat, and Horozcu offer different representations for this return to naturality/nature in their individualistic poems. In other words, each Garip poet has his own particular contribution in the process –what can be called– "the greening of the modern Turkish poetry" with their distinctive styles. The poets' contributions are analyzed here within the line of the deep ecological theory, formulated by the Norwegian philosopher Arne Naess upon the basic principles of "ecocentrism," "richness and diversity of life forms" (68), "Self-realization," and "universal symbiosis" (80).

description: Background: Pyrosequencing can be applied for Single-Nucleotide-Polymorphism (SNP)-based pathogen typing or for providing sequence information of short DNA stretches. However, for some pathogens molecular typing cannot be performed relying on a single SNP or short sequence stretch, necessitating the consideration of several genomic regions. A promising rapid approach is the simultaneous application of multiple sequencing primers, called multiplex pyrosequencing. These primers generate a fingerprint-pyrogram which is constituted by the sum of all individual pyrograms originating from each primer used. Methods: To improve pyrosequencing-based pathogen typing, we have developed the software tool MultiPSQ that expedites the analysis and evaluation of multiplex-pyrograms. As a proof of concept, a multiplex pyrosequencing assay for the typing of orthopoxviruses was developed to analyse clinical samples diagnosed in the German Consultant Laboratory for Poxviruses. Results: The software tool MultiPSQ enabled the analysis of multiplex-pyrograms originating from various pyrosequencing primers. Thus several target regions can be used for pathogen typing based on pyrosequencing. As shown with a proof of concept assay, SNPs present in different orthopoxvirus strains could be identified correctly with two primers by MultiPSQ. Conclusions: Software currently available is restricted to a fixed number of SNPs and sequencing primers, severely limiting the usefulness of this technique. In contrast, our novel software MultiPSQ allows analysis of data from multiplex pyrosequencing assays that contain any number of sequencing primers covering any number of polymorphisms.
A comparative analysis of identity construction in digital academic discourse: Tunisian EFL students as a case study
Creators: name: Fendri, Emna
Publisher: name: Universit� degli studi di Bergamo
Year: 2020

description: The value of academic research does not only reside in the observations and the conclusions it reaches but also in the scientific debate it raises within a community of interest (Swales 1990; Gosden 1992; Vallis 2010; Nackoney/Munn/Fernandez 2011). Doing academic research online through digital media takes academic discourse from the immediate and local research context to a wider and more heterogeneous community. The examination of written papers in different contexts might reveal something about the way writing is perceived by the writer. The present paper compares and contrasts interactional metadiscourse use in both traditional and digital academic discourse following Hyland?s (2005) model of METADISCOURSE. A corpus of ten MA dissertations as an example of traditional communication and ten internship reports as an example of digital communication written by Tunisian EFL students is examined. A qualitative and quantitative analysis is carried out using the Text Inspector web tool and manual annotation. The results reveal that, except for boosters, the use of interactional markers significantly differs across the media. The overall tone that METADISCOURSE use creates in dissertation writing reflects an audience-centered way of meaning-making while digital communication is distinguished by a stronger writer authorial presence.

description: Background: It remains unclear to what extent asthma in adults is linked to allergic rhinitis (AR), gastroesophageal reflux disease (GERD), and acetylsalicylic acid exacerbated respiratory disease (AERD), and how these comorbidities may affect asthma outcomes in the general population. We therefore aimed to assess the prevalence of these major comorbidities among adults with asthma and examine their impact on asthma exacerbations requiring hospital care. Methods: A total of 22,050 adults 18 years and older were surveyed in the German National Health Telephone Interview Survey (GEDA) 2010 using a highly standardized computer-assisted interview technique. The study population comprised participants with self-reported physician-diagnosed asthma, among which the current (last 12 months) prevalence of AR and GERD-like symptoms (GERS), and life-time prevalence of AERD was estimated. Weighted bivariate analyses and logistic regression models were applied to assess the association of each comorbid condition with the asthma outcome (any self-reported asthma-related hospitalization and/or emergency department (ED) admission in the past year). Results: Out of 1,136 adults with asthma, 49.6% had GERS and 42.3% had AR within the past 12 months; 14.0% met the criteria of AERD, and 75.7% had at least one out of the three conditions. Overall, the prevalence of at least one exacerbation requiring emergency room or hospital admission within the past year was 9.0%. Exacerbation prevalence was higher among participants with comorbidities than among those without (9.8% vs. 8.2% for GERS; 11.2% vs. 7.6% for AR, and 22.2% vs. 7.0% for AERD), but only differences in association with AERD were statistically significant. A strong association between asthma exacerbation and AERD persisted in multivariable logistic regression analyses adjusting for sex, age group, level of body mass index, smoking status, educational attainment, and duration of asthma: odds ratio (OR) = 4.5, 95% confidence interval (CI) = 2.5–8.2. Conclusions: Data from this large nation-wide study provide evidence that GERS, AR and AERD are all common comorbidities among adults with asthma. Our data underline the public health and clinical impact of asthma with complicating AERD, contributing considerably to disease-specific hospitalization and/or ED admission in a defined asthma population, and emphasize the importance of its recognition in asthma care.

description: Purpose: Although it is widely accepted that physical activity (PA) positively, and screen-based media use (SBM) negatively, affects well-being, there is a lack of studies relating PA and SBM to health-related quality of life (HRQoL) in adolescents. We examined these associations in German adolescents for different HRQoL subdomains and explored the role of body satisfaction as a possible mediator. Methods: The 11–17-year-old subsample of the German Health Interview and Examination Survey (2003–2006) was analysed (N = 6813; 51.3% male). Cross-sectional associations of self-reported PA frequency and amount of daily SBM with HRQoL subscale scores (according to KINDL-R) were examined by hierarchical linear regression models, adjusting for the clustering of the sample and for a variety of possible confounders. The size and significance of indirect effects via body (dis)satisfaction (BDS) were examined by mediation analyses. Results: Higher PA frequency was significantly associated with higher HRQoL on nearly all subscales and dose–response-relationships were observable. Variations were greatest in terms of social well-being in boys (effect size d = 0.59) and physical well-being in girls (d = 0.43). Higher SBM was related to lower HRQoL on all subscales in girls and on some subscales in boys, with the largest effects for school functioning in both genders (d = 0.31 and 0.37, respectively). The mediated effects for PA and SBM were significant in both genders, but the sizes and the proportions of total effects mediated by body satisfaction were rather small. Conclusions: Higher PA frequency was associated with higher self-reported HRQoL, and higher SBM was associated with lower self-reported HRQoL in both genders, even after adjusting for relevant covariates. The results support the assumption of independent health impacts of both behaviours, although no causal relationship can be confirmed with these cross-sectional data. Mechanisms other than body satisfaction must largely account for the effects of PA and SBM on well-being.

Financial models with L�vy processes

Publisher: name: Universit� degli studi di Bergamo
Year: 2008

description: This dissertation studies option pricing, portfolio selection, and risk management assuming exponential-L�vy models in ?nancial markets. Option pricing of European, American, and path-dependent derivatives is dealt with the markovian approach. Markovian approach has been introduced by Duan and Simonato [26] to price American options under Wiener and GARCH processes, and then Duan et al. [27] has shown how to price barrier options. This dissertation proposes to extend the markovian approach to L�vy processes and shows numerical results where the price convergence is observed. European, American, and barrier options are priced using the same procedure of Duan et al., while for compound and lookback options we propose a new pricing method. Speci?cally, we explain how to price compound and lookback options assuming a Markov chain evolutions of the asset price. Portfolio selection is studied assuming ?nancial markets where asset log returns follow subordinated L�vy processes. Firstly, we propose a Mean-Value at Risk analysis under two ?nancial markets, one without transaction costs, and the other one with proportional and constant transaction costs. Secondly, we study a multi-period model with unlimited short sales where investors look only at the mean and variance of the ?nal wealth. Finally, we propose a Mean-Variance-Skewness analysis assuming a ?nancial market with no short sales and without transaction costs. Our numerical results con?rm the better performance of the studied subordinated L�vy processes with respect the Normal model. Risk management is studied proposing two conditional heteroscedastic models of portfolio returns. The ?rst one is an extension of the EWMA RiskMetrics model and assumes L�evy distributed returns. The second one is a more sophisticated analysis and consists in a generalization of the GHICA model of Chen et al. [17].

description: The use of monoclonal antibodies directed against membrane proteins of leukocytes has greatly contributed to our understanding of the function and development of the immune system. Meanwhile these reagents provide valuable tools in many fields of research, stretching far beyond immunology and hematology. For guinea pigs only a limited number of such reagents have been described, and the information about availability and specificity is scattered over many years and journals. We provide an overview on the monoclonal antibodies produced since the technique was applied first in this species, with a focus on those reagents which have been characterized in more detail, and which should still be available either commercially or directly from the labs that created them.
Advancing Optimal Control Theory Using Trigonometry For Solving Complex Aerospace Problems
Creators: name: Mall, Kshitij
Publisher: name: Purdue University Graduate School
Year: 2019
Subjects: Aerospace engineering not elsewhere classified

description: Optimal control theory (OCT) exists since the 1950s. However, with the advent of modern computers, the design community delegated the task of solving the optimal control problems (OCPs) largely to computationally intensive direct methods instead of methods that use OCT. Some recent work showed that solvers using OCT could leverage parallel computing resources for faster execution. The need for near real-time, high quality solutions for OCPs has therefore renewed interest in OCT in the design community. However, certain challenges still exist that prohibits its use for solving complex practical aerospace problems, such as landing human-class payloads safely on Mars.
In order to advance OCT, this thesis introduces Epsilon-Trig regularization method to simply and efficiently solve bang-bang and singular control problems. The Epsilon-Trig method resolves the issues pertaining to the traditional smoothing regularization method. Some benchmark problems from the literature including the Van Der Pol oscillator, the boat problem, and the Goddard rocket problem verified and validated the Epsilon-Trig regularization method using GPOPS-II.
This study also presents and develops the usage of trigonometry for incorporating control bounds and mixed state-control constraints into OCPs and terms it as Trigonometrization. Results from literature and GPOPS-II verified and validated the Trigonometrization technique using certain benchmark OCPs. Unlike traditional OCT, Trigonometrization converts the constrained OCP into a two-point boundary value problem rather than a multi-point boundary value problem, significantly reducing the computational effort required to formulate and solve it. This work uses Trigonometrization to solve some complex aerospace problems including prompt global strike, noise-minimization for general aviation, shuttle re-entry problem, and the g-load constraint problem for an impactor. Future work for this thesis includes the development of the Trigonometrization technique for OCPs with pure state constraints.

description: Early processes following photon absorption by the photosynthetic pigment-protein complex photosystem I (PS I) have been the subject of decades of research, yet many questions remain in this area of study. Among the trickiest to investigate is the role of the PS I reaction center’s (RC’s) two accessory (A‑1) chlorophyll (Chl) cofactors as primary electron donors or acceptors, oxidizing the special pair (P700) of Chls or reducing a nominal primary electron acceptor (A0) Chl in the first electron transfer step. Such processes, which occur on a picosecond timescale, have long been studied via ultrafast spectroscopy, though difficulty lies in distinguishing among signals from early processes, which have similar lifetimes and involve many identical pigments. In this work, we used steady-state and ultrafast optical pump-probe spectroscopies on PS I trimers from wildtype and mutant strains of the cyanobacterium Synechocystis sp. PCC 6803 in which an asparagine amino acid residue near A‑1 had been replaced with methionine on one or both sides of the RC. We also conducted an identical set of experiments on mutants in which A0 was similarly targeted, as well as studied the effects on the A0 absorption spectrum of a third category of mutations in which a peripheral H‑bond to A0 was lost. Steady-state absorption spectroscopy revealed that many of these mutations caused mild Chl deficiencies in the light-capturing antenna of PS I without necessarily preventing organisms’ growth. More importantly, we determined that contrary to certain hypotheses, A‑1 is the most likely true first electron acceptor, as reasoned from observing rapid triplet state formation in double A‑1 mutants. We also concluded from non-additive detrimental effects of single-side mutations that if one RC branch is damaged at the level of A0 or A‑1, electron transfer may be redirected along the intact branch. This may help explain the conservation of two functional RC branches in PS I over many generations of natural selection, despite the additional cost to organisms of manufacturing both.

description: To understand the Oulipo's forays into computer science and more importantly, why they abandoned them, I designed and carried out one of the inaugural projects of the Princeton Center for Digital Humanities. The goal was twofold: first, through exploratory programming, I intended to create interactive, digital annexes to accompany my doctoral dissertation; more importantly, I hoped that by attempting to reproduce the Oulipo's own algorithmic efforts, I would gain similar insights into the nature of "Potential Literature" and be able to understand why the group abandoned such efforts after the 1970s.  This article describes the content, development, and results of my project. For each of my three Python-based annexes, I offer a historical survey of the Oulipian text or procedure discussed within and the Oulipo’s own proto-digital humanities experiments; then, I will talk about my own experiences as a coder-researcher, what learning Python has brought to my project, and how my exploratory programming offered me a new kind of critical reflection. Establishing these annexes forced me to learn to code, a type of work that does not only produce digital texts, but also helped me to reflect on the notion of chance in a more nuanced way. Finally, coding has allowed me to better understand the Oulipian mentality concerning this sort of digital experimentation.

description: Legged systems have potentials of better mobility than traditional wheeled and tracked vehicles on rough terrain. The reason for the superior mobility of legged
systems has been studied for a long period and plenty of robots using legs for locomotion have been developed during recent few decades. However the built
legged robots still exhibit insufficiency of expected locomotive ability comparing with their counterparts in nature with similar size. The reason may be complicated
and systematic associated with several aspects of the development such as the design, key components, control & planning and/or test and evaluation. The goal
of this thesis is to close the gap between legged robots research & development and practical application and deployment. The research presented in this thesis
focuses on three aspects including morphological parameters of quadruped robots, optimal design for knee joint mechanism and the development of a novel test
bench? Terrain Simulator Platform.
The primary motivation and target for legged robots developing is to overcome the challenging terrain. However few legged robots take the feature of terrain
into consideration when determining the morphological parameters, such as limb length and knee orientation for robots. In this thesis, the relationship between
morphological parameters of quadruped robots and terrain features are studied by taking a ditch/gap as an example. The influence of diverse types of morphological
parameters including limb length, limb mass, the center-of-mass position in limbs and knee configuration on the ditch crossing capability are presented.
In order to realize extended motion range and desired torque profile, the knee joint of HyQ2max adopts a six-bar linkage mechanism as transmission. Owing to
the complexity of closed-loop kinematic chain, the transmission ratio is difficult to design. In this thesis, I used a static equilibrium based approach to derive the
transmission relationship and study the singularity conditions. Further desired torque profile of knee joint are realized by a multi-variable geometric parameters
optimization.
For the test and performance evaluation of robotic leg, I designed and constructed a novel test bench? Terrain Simulator Platform (TSP). The main function of the TSP is to provide sufficient test conditions for robotic leg by simulating various terrain features. Thus working status of robotic leg can be known before the construction of the whole robot. The core of the TSP is a 3-PRR planar parallel mechanism. In this thesis, the structure design and implementation, the kinematics including singularity, workspace etc, and dynamics of this 3-PRR mechanism are presented.

Masculinity, War, and Pursuit of Glory in Sepúlveda’s Gonzalo

description: The Dialogus de appetenda gloria qui inscribitur Gonsalus (1523) is Juan Gine´s de Sepu´ lveda’s first reflection on the moral aspects of war. In it, he addresses whether it is morally licit for Christians to desire worldly honor and glory, a question that Christian mystics, Irenicists, and humanists like Desiderius Erasmus and Juan Luis Vives posed in writings through which they sought to renew and reform spiritual practices in Christendom. Their skepticism was linked to a larger doubt over the compatibility of Christian principles that commanded men to love one another and the state’s injunction to kill one’s fellow man. In redressing those concerns, Sepúlveda advances a theory that embraces the pursuit of glory and that serves as the foundation for his justificatory theories of war in subsequent writings. His discourse on glory accommodates social mobility, simultaneously inscribing a martial moral code on the terrain of the masculine self and the male body.

Platelet derivatives: from bench to bedside. Molecular characterization of the effect of platelet derivatives on cells and their use for skin chronic ulcer treatment

description: Abstract
The present paper is related to the field of cell culture medium supplements. In particular, it refers
to (i) an heparin-free human Platelet Lysate devoid of serum or plasma components (v-PL) and (ii)
an heparin-free human serum devoid of platelet lysate components (Pl-s), and to their use as single
components or in combination in primary or cell line cultures.
Human Mesenchymal Stem Cells (MSC) primary cultures were obtained from adipose, bonemarrow
and umbilical cord. The cumulative cell doubling number in the presence of the different
culture medium supplements was determined at different culture times. In general, MSC expanded
in the presence of Pl-s alone showed a low or no proliferation in comparison to cells grown with the
combination of Pl-s and v-PL. Confluent, growth arrested cells, either human MSC or human
articular chondrocytes, treated with v-PL resumed proliferation, whereas control cultures, not
supplemented with v-PL, remained quiescent and did not proliferate. Interestingly, signal
transduction pathways distinctive of proliferation were activated also in cells treated with v-PL in
the absence of serum, when cell proliferation did not occur, indicating that v-PL could induce the
cell re-entry in the cell cycle (cell commitment), but the presence of serum proteins was an
indispensable requirement for cell proliferation to happen. Indeed, Pl-s alone supported cell growth
in constitutively activated cell lines (U-937, HeLa, HaCaT, V-79) regardless the co-presence of v-
PL. Plasma and plasma-derived serum were equally able to sustain cell proliferation although, for
cells cultured in adhesion, the Pl-s was more efficient than the plasma from which it was derived.
Moreover, cell expanded in the presence of the new additives maintained their differentiation
potential and did not show alterations in their karyotype.
In a different work we showed how Platelet Lysate (PL) derived from Platelet Rich Plasma (PRP)
was capable to support growth and isolation of MSC (Mesenchymal Stromal Cell). However, the
molecular mechanisms involved in these processes were still unknown. We focused our attention on
a family of highly conserved proteins involved in different cellular mechanisms such as cell growth,
proliferation and apoptosis, MYC's family. In particular, MYC is a transcription factor that activates
or inhibits the transcription of several genes by interacting with other proteins.
The three proteins of C-MYC gene have the same c-terminal part, differing in the N-terminal region
due to an alternative translation at the start site. The three forms are C-MYC1, C-MYC2 and CMYCS,
differently expressed during cell growth.

description: Conventional rocket propellants such as monomethyl hydrazine (MMH) and hydrazine have been used for decades due to their high specific impulse and performance. However, interest in greener alternatives, including HAN or HAN-based propellants, has grown due to high levels of toxicity and difficulties in the handling and storage of conventional fuels. Included among potential propellants are monopropellants nitromethane (NM) and isopropyl nitrate (IPN) and their blends. Though large-scale investigations on the ignition and combustion of these fuels have been done, the ignition and combustion processes of these monopropellant fuels are still not well understood. Droplet studies have been traditionally and extensively employed to decipher the influence of ambient conditions and fuel properties on ignition and combustion of different fuels. These fundamental studies allow for the isolation of different factors such as ambient temperature and initial droplet size among others, to provide a deeper understanding of their effects in overall spray combustion. The research described here seeks to add to the knowledge on the ignition and combustion processes of NM and IPN through single droplet ignition and combustion studies. To this end, the first effort has been to establish a suitable method of studying the ignition and combustion of droplets in conditions similar to those in practical systems. Droplet ignition delay measurements for NM and IPN droplets have also been conducted, and the influence of ambient temperature and droplet size has been studied. The double flame structures of NM and IPN, representative of hybrid combustion, have also been observed. In addition, the applicability of the hybrid combustion model, developed to predict mass burning rates for hypergolic fuels exhibiting hybrid burning including MMH, UDMH and hydrazine, has been assessed. Lastly, the ability of the quasi-steady droplet ignition model to predict ignition delays of IPN and NM monopropellant droplets is also discussed.
