Abstract:
The development of large-scale fireballs is a typical result of explosions associated with accidental fuel releases in the oil and process industries. The two major mechanisms that lead to fireball formation are vapour cloud explosions and boiling liquid expanding vapour explosions (BLEVEs). An ability to model fireballs is extremely important from the point of view of safety and risk analysis. The present paper provides a state-of-the-art review of the computational techniques available for the mathematical modelling of fireballs. The emphasis is placed on computational fluid dynamics (CFD) modelling, based on Reynolds-averaged Navier—Stokes (RANS) equations for reactive flow. The results of calculations and estimations of fireball hazards are compared with available experimental data. New results are presented for problems that are usually given less attention in fireball studies. These concern estimations of air entrainment rates into fireballs and potential strategies for fireball suppression.

Abstract:
Aggregations in insects carry out diverse functions, and gregariousness may also act as an antipredatory strategy, especially when combined with warning signalling. Despite many studies focused on the antipredatory function of gregariousness, there are still aspects needing further investigation: What aspects of predator behaviour are affected by prey gregariousness? Which of the antipredatory effects of aggregations are linked with aposematic coloration, and which will also work for non-aposematic prey? Does gregariousness of an aposematic species affect its mimetic relationships? We have studied these topics in the firebug, Pyrrhocoris apterus (Heteroptera), an aposematic red-and-black true bug with moderate chemical defence. Firebugs alternate between solitary and gregarious lifestyles throughout the year. We used hand-reared great tits (Parus major) as naive predators, and subjected them to avoidance training with either solitarily or gregariously presented firebugs, followed by a memory test with solitary individuals. To test whether effects of gregariousness are specific for the aposematic firebugs, we tested another group of birds with brown-painted firebugs. Our results show that the gregarious lifestyle of the firebug is a part of its antipredatory strategy. Compared to solitary individuals, aggregations benefited in several ways, some exclusive for aposematic firebugs, others working irrespective of coloration. Aggregations induced greater innate wariness, leading to longer attack latencies and more cautious prey handling, including complete attack avoidance in some birds. Despite the fact that the birds mostly attacked only one or two individuals from an aggregation, they needed fewer trials to reach the avoidance-learning criterion than the birds learning to avoid solitary firebugs. Birds’ experience with firebug aggregations reduced the predation risk of subsequently encountered solitary individuals, as the birds hesitated longer before attacking a solitary firebug if their previous aversive experience had been with aggregations rather than with solitary individuals. Predators’ experience with firebug aggregations may compensate for the firebugs’ moderate chemical defence, and as a consequence, gregariousness may change the firebugs’ mimetic relationships with better defended red-and-black true bug species from quasi-Batesian to Müllerian.

Abstract:
This paper presents evidence of an apparent connection between ball lightning and a green fireball. On the evening of the 16 May 2006 at least three fireballs were seen by many people in the skies of Queensland, Australia. One of the fireballs was seen passing over the Great Divide about 120 km west of Brisbane, and soon after, a luminous green ball about 30 cm in diameter was seen rolling down the slope of the Great Divide. A detailed description given by a witness indicates that the phenomenon was probably a highly luminous form of ball lightning. A hypothesis presented in this paper is that the passage of the Queensland fireball meteor created an electrically conductive path between the ionosphere and ground, providing energy for the ball lightning phenomenon. A strong similarity is noted between the Queensland fireball and the Pasamonte fireball seen in New Mexico in 1933. Both meteors exhibit a twist in the tail that could be explained by hydrodynamic forces. The possibility that multiple sightings of fireballs across southeast Queensland were produced owing to fragments from comet 73P Schwassmann–Wachmann 3 is discussed.

Abstract:
ABSTRACT The disruption of asteroids and comets produces cm-sized meteoroids that end up impacting the Earth’s atmosphere and producing bright fireballs that might have associated shock waves or, in geometrically favourable occasions excavate craters that put them into unexpected hazardous scenarios. The astrometric reduction of meteors and fireballs to infer their atmospheric trajectories and heliocentric orbits involves a complex and tedious process that generally requires many manual tasks. To streamline the process, we present a software package called SPMN 3D Fireball Trajectory and Orbit Calculator (3D-firetoc), an automatic Python code for detection, trajectory reconstruction of meteors, and heliocentric orbit computation from video recordings. The automatic 3D-firetoc package comprises of a user interface and a graphic engine that generates a realistic 3D representation model, which allows users to easily check the geometric consistency of the results and facilitates scientific content production for dissemination. The software automatically detects meteors from digital systems, completes the astrometric measurements, performs photometry, computes the meteor atmospheric trajectory, calculates the velocity curve, and obtains the radiant and the heliocentric orbit, all in all quantifying the error measurements in each step. The software applies corrections such as light aberration, refraction, zenith attraction, diurnal aberration, and atmospheric extinction. It also characterizes the atmospheric flight and consequently determines fireball fates by using the α − β criterion that analyses the ability of a fireball to penetrate deep into the atmosphere and produce meteorites. We demonstrate the performance of the software by analysing two bright fireballs recorded by the Spanish Fireball and Meteorite Network (SPMN).

Abstract:
We derive formulas describing the induced production of bosons via fireball emissions. If the fireball volume is large, induced emission is unimportant and we get back to the usual independent emission model. Induced emission due to the Bose-Einstein statistical nature of bosons is however very important for small fireballs, from which we obtain greatly enhanced production rates and very unusual charge distributions. This can explain the cosmic ray Centauro events if the fireball has an energy density of the order of 1 TeV/(fm) 3. We suggest that this density may be feasible if preons do exist.

Abstract:
AbstractIn the last several years the manually operated fish-eye cameras in the Czech part of the European fireball Network (EN) have been gradually replaced with new generation cameras, the modern and sophisticated completely autonomous fireball observatories (AFO), which were recently developed in the Czech Republic. The main motivation for construction of this new observing system was to continue in regular fireball observations and to make these observations more complex and efficient. In this paper we briefly describe basic design and work of this new instrument and its deployment at the Czech stations of the EN. The current dislocation of the individual stations and their equipment is also discussed. Along with this new modern instrument we developed also new software for measurement of photographic negatives which makes this time consuming work more efficient and easier. The AFOs provide us with data on fireballs far richer and more interesting than those we were able to get in the past. This is illustrated by the cases of two recently observed fireballs which were recorded by the AFOs. We describe the high precision of all the measureded values as well as the very detailed information about light curves in both cases.

Abstract:
Galileo observations in the UV, visible, and infrared uniquely characterize the luminous phenomena associated primarily with the early stages of the impacts of SL9 fragments—the bolide and fireball phases—because of the spacecraft's direct view of the impact sites. The single luminous events, typically 1 min in duration at near-IR wavelengths, are interpreted as initial bolide flashes in the stratosphere followed immediately by development of a fireball above the ammonia clouds, which subsequently rises, expands, and cools from ∼ 8000 K to ∼ 1000 K over the first minute. The brightnesses of the bolide phases were remarkably similar for disparate events, including L and N, which were among the biggest and smallest of the impacts as classified by Earth-based phenomena. Subsequent fireball brightnesses differ much more, suggesting that the similar-sized fragments were near the threshold for creating fireballs and large dark features on Jupiter's face. Both bolides and fireballs were much dimmer than had been predicted before the impacts, implying that impactor masses were small (∼0.5km diameter). Galileo data clarify the physical interpretation of the “first precursor,” as observed from Earth: it probably represents a massive meteor storm accompanying the main fragment, peaking ∼10s before the fragment penetrates to the tropopause; hints of behind-the-limb luminous phenomena, recorded from Earth immediately following the peak of the first precursor, may be due to reflection of the late bolide/early fireball stages from comet debris very high in Jupiter's atmosphere.

Abstract:
We present 25 photographic fireballs belonging to the September epsilon Perseid (SPE, IAU #208) meteor shower observed by the Czech part of the European Fireball Network in 2013–2017. Exceptional high activity of bright photographic fireballs was observed in 2013, while a lower activity, but still higher than in other years, was observed in the period of 2015–2017. Physical properties of these SPE fireballs were studied and compared to other meteor showers. Perseids are found to be the closest analog to SPE. Corrected geocentric radiant of the 2013 outburst fireballs was determined for solar longitude 167.20° and has right ascension 47.67 ± 0.04° and declination 39.493 ± 0.013° (J2000.0). On the basis of determined heliocentric orbits the parent body of the shower is an unknown long-period comet on retrograde orbit with an orbital period of the order of a thousand years.

Abstract:
ABSTRACT Meteoroids impacting the Earth atmosphere are commonly classified using the PE criterion. This criterion was introduced to support the identification of the fireball type by empirically linking its orbital origin and composition characteristics. Additionally, it is used as an indicator of the meteoroid tensile strength and its ability to penetrate the atmosphere. However, the level of classification accuracy of the PE criterion depends on the ability to constrain the value of the input data, retrieved from the fireball observation, required to derive the PE value. To overcome these uncertainties and achieve a greater classification detail, we propose a new formulation using scaling laws and dimensionless variables that groups all the input variables into two parameters that are directly obtained from the fireball observations. These two parameters, α and β, represent the drag and the mass-loss rates along the luminous part of the trajectory, respectively, and are linked to the shape, strength, ablation efficiency, mineralogical nature of the projectile, and duration of the fireball. Thus, the new formulation relies on a physical basis. This work shows the mathematical equivalence between the PE criterion and the logarithm of 2αβ under the same PE criterion assumptions. We demonstrate that log(2αβ) offers a more general formulation that does not require any preliminary constraint on the meteor flight scenario and discuss the suitability of the new formulation for expanding the classification beyond fully disintegrating fireballs to larger impactors including meteorite-dropping fireballs. The reliability of the new formulation is validated using the Prairie Network meteor observations.

Сьогодні важко уявити наше життя без інтернету. Інтернет сторінки поступово вилучають з обігу паперові документи і джерела інформації. З кожним роком набирає популярності система он-лайн кабінетів платників комунальних послуг з метою своєчасного обліку їх надання та отримання. Для підприємств, що надають комунальні послуги є актуальним своєчасний облік їх надання та використання споживачем. Створення та експлуатація он-лайн кабінетів споживачів та платників комунальних послуг сприяє вдосконаленню обліку наданих комунальних послуг, збільшенню якості надання послуг та, відповідно, збільшення прибутку. На сьогодні JavaScript є найпопулярнішою мовою програмування, що обумовлено, як на мою думку, невибагливістю мови – для того, аби виконати написаний скрипт, в найпростішому випадку достатньо просто відкрити сторінку консолі в браузері. До того ж, існує велика кількість сторонніх бібліотек, які дають змогу для вживаних тривіальних задач використати існуючий код, тим самим, пришвидшити розробку.

Abstract:
The development within the textile industry is always ongoing with development of new and better textiles, which often mean the use of non-natural materials like polyester. This doesn’t line up with the work shared around the world against an improved environment, so the idea came to use a form of linen fibers instead of polyester as the reinforcing material together with cotton. The idea was to use flax, linen of low quality, which is seen as a waste product and garbage in the production of high quality linen and flax seed oil. This flax of low quality needs to be separated before it can be used in cotton spinning machines. Fireball 2 is just that, a process to separate flax fibers through the treatment of a technique called electrohydraulic discharge. The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber. To achieve this goal the process is described, which phenomenon that treat the flax fibers and how they arise, as well as the components included in the system. Much of the work involves tests of different electrodes as it shows that the electrode strongly contributes to the discharge property, which is very important for the systems ability to treat flax. Fireball 2 is marketed as an environmental technique as it doesn’t require any chemical additives for the separation; the only thing needed is flax, water and electricity. For it to be considered environmentally friendly is has to be efficient, therefore the thesis rapport discuss the discharge efficiency. The result of the fiber separation tests show that Fireball 2 separates flax with good results, both in the form of analysis of separated fibers as well as energy efficiency. Measures under performed tests have shown that the efficiency is high, close to 100 percent of the energy stored in the system is released during treatment of the flax. Analysis made at De Montfort University of the treated flax show that the flax is well separated. When it comes to the electrode an satisfactory design of the electrodes conductive part have been found during this thesis work, although more work is required to find an isolation material that can withstand the high strain that the plasma channel cause.
Utvecklingen inom textilindustrin gar standigt framat med utveckling av nya och battre textiler, vilket ofta innebar anvandning av icke naturliga material som polyester. Da detta inte gar i linje med det ovriga arbetet runt om i varlden mot en forbattrad miljo, fanns en ide att anvanda lin fibrer istallet for polyester som forstarkningsmaterial tillsammans med bomull. Iden var att anvanda flax, vilket ar lin av lagre kvalitet, som anses vara en restprodukt och avfall vid produktionen av hogkvalitativt lin och linolja. Detta lin av lag kvalitet maste separeras innan det kan anvandas i spinnmaskiner for bomull och Fireball 2 ar just en process for att separera flax fibrer genom att behandla dem med en teknik kallad elektrohydraulisk urladdning. Examensarbetets mal ar att utvardera Fireball 2 processens formaga att separera lin fibrer. For att kunna gora detta beskrivs processen, vilka fenomen som behandlar flax fibrerna och hur dessa uppkommer, samt systemets uppbyggnad med de olika komponenterna. Mycket av arbetet involverade tester av olika elektroder, da det visade sig att just elektroden bidrog starkt till urladdningens egenskaper som ar valdigt viktig for systemets formaga att behandla flax. Fireball 2 marknadsfors som en miljovanlig teknik da den inte kraver nagra kemiska tillsatser for separeringen, det anda som behovs ar flax, vatten och elektricitet. For att den ska anses vara miljovanlig maste effektiviteten vara hog, darfor behandlar rapporten urladdningens effektivitet. Resultatet fran fibersepareringstesterna visar att Fireball 2 processen separerar flax med goda resultat, bade i form av analyser av separerade fibrer som energi effektivitet. Matningar under utforda tester har visat att effektiviteten ar hog, nara 100 procent av energin lagrad i systemet anvands for att behandla flax fibrerna, vilket ar nara optimalt. Samtidigt visar analyser gjorda pa De Montfort Universitetet i Leicester att det behandlade flaxet ar val separerat. Vad det galler arbetet med elektroden sa har en tillfredstallande utformning av elektrodens ledande del hittades under utforandet av detta examensarbete, dock kravs fortsatt arbete med att hitta ett isolationsmaterial som kan motsta de hoga pafrestningar som plasma kanalen astadkommer.

"Suspended in Mid-Air while Looking under the Bed" begins and loosely foreshadows this collection of poetry and short stories. I am a storyteller, pulled by both family and place in my life. In this thesis, I play impresario and follow each short story with poems which resonate with that story. The first poems and short stories speak from places in my life: Ireland, Prague, and Malawi. Then my storytelling comes closer to family with a fictional account of my great-grandparents Wilhelm and Ana Krane, who immigrated to Allegheny City, Pennsylvania, in the 1880's. My story of family continues through relationships, reunions, my parents, and ends with the contemporary world when my translation of Charles Baudelaire merges into a poem about Iraq.

Abstract:
This purpose of this research was to develop a credible set of furniture design fires for residential/apartment buildings and determine a methodology for incorporating compartment effects in design fires. Design fires can be defined using various outputs, the most important being the HRR profile, and depending on the application the following may also be relevant: · Smoke production rates · Soot yield · Species production rates · Temperature profiles · Visibility · Heat fluxes · Mass loss rate of the fuel · Flame spread There were three phases to this project: The first phase of this project was a comprehensive data and literature review to determine the amount of experimental data available and commonly accepted burning characteristics for upholstered furniture; armchairs, 2-seater sofas, 3-seater sofas, beds and bedding assemblies, and commonly accepted burning characteristics and compartment effects. A large proportion of the review provided only qualitative guidance for design fires. In the second phase the data collected during the review was collated and used to quantitatively analyse key fire characteristics. These were · peak HRR, · time to peak HRR, · growth rate, · total heat released and · maximum CO/CO2 ratio. A methodology was developed to statistically analyse experimental data using BestFit, and where there was sufficient data the 98th percentile of the statistical analysis was used as a quantitative guide for furniture design fires. Similarly, compartment effects were incorporated into the design fires by analysing and comparing the experimental data from free burn and room burn tests of the same furniture item. The same statistical analysis was used to determine likely changes in the key fire characteristics mentioned above. A methodology for determining design fires for upholstered furniture was devised, however the small number of data sets available for analysis meant the quantitative results were only indicative. The third phase was to attempt to model furniture fires using FDS, which determined that at the time of this project, FDS was not capable of modelling simple furniture fires accurately. The simulation results varied significantly from the experimental results and a number of limitations were identified. Therefore FDS should not be used to create design fires using the heat of combustion method, which relies on the users’ definition of material properties.

Abstract:
A three-colour pyrometer is built and used to record the transient visible radiation emitted by a fireball produced when a condensed explosive is detonated. Measurements of the radiant intensity at several narrow wavelength bands are used to estimate the temperature of the products within the fireball. For conventional oxygen-deficient homogeneous explosives (TNT and nitromethane), the radiant intensity reaches a maximum typically after tens of milliseconds, but the measured fireball temperature remains largely constant for more than 100 ms, at a value of about 2 000 K, consistent with predictions using equilibrium thermodynamics codes. When combustible metal particles such as aluminium, magnesium or zirconium are added to the explosive, reaction of the particles enhances the radiant energy and the fireball temperature is increased. In this case, the fireball temperatures are lower than equilibrium predictions, but are consistent with measurements of particle temperature in single particle ignition experiments.

Abstract:
Abstract Remote sensors in the infrared region can be used to study the progression of fireballs generated from experiments involving high explosives (HE). Developing an improved understanding of HE fireballs can be used to validate and improve computational physics codes that simulate such events. In this paper, Bayesian approaches are studied to estimate time-dependent optimal fireball parameters and their uncertainties using Fourier transform infrared (FTIR) spectroscopy. The optical signal measured by an FTIR sensor provides information on the fireball due to thermal emission, particulate emission/absorption, and HE gas product emission/absorption from the fireball. FTIR sensors have the advantage of being able to capture and measure the radiance in a large part of the infrared spectrum. The parameters to be estimated from the fireball include temperature and size, soot quantity, gas species concentrations (e.g., H2O, CO2, CO), and information on the presence of metals. In general, this inverse optimization problem is difficult due to the estimated quantities being correlated, the low spectral resolution of the FTIR sensor, and the intervening atmosphere absorbing the radiation emitted from the fireball. Bayesian calibration and Bayesian model averaging are applied to address these difficulties and to quantify the uncertainty in the estimated optimal parameter values. The fireball parameter settings are evaluated by the fit of a simplified spectral model to FTIR data. The overall problem will be presented together with a description of the Bayesian approaches. In this paper, the Bayesian approaches are applied to artificially generated FTIR data to illustrate the approach.
