We have examined the constraints on the anomaloustqγ (q=u,c)couplings through the processpp→pγp→pWbXat the LHC by considering four forward detector acceptances:0.0015<ξ<0.5,0.0015<ξ<0.15,0.015<ξ<0.15, and0.1<ξ<0.5, whereξ=Eγ/EwithEγandEthe energies of the photon and of the incoming proton, respectively. The sensitivity bounds on the anomalous couplings have been obtained at the 95% confidence level in a model independent effective Lagrangian approach. We have found that the bounds on these couplings can be highly improved compared to current experimental bounds.

This brief review deals with recent interest in the prospects of observing a Massive Metastable Charged Particle (MMCP) at the Large Hadron Collider (LHC), and measuring its properties there. We discuss the motivation for scenarios with MMCPs in a phenomenological context, focusing on supersymmetric models that allow us to explore the expected experimental signatures of MMCPs at the LHC. We review current bounds and give estimates of the LHC reach in terms of MMCP masses.

Theoretical and experimental techniques employed in dedicated searches for dark matter at hadron colliders are reviewed. Bounds from the 7 TeV and 8 TeV proton–proton collisions at the Large Hadron Collider (LHC) on dark matter interactions have been collected and the results interpreted. We review the current status of the Effective Field Theory picture of dark matter interactions with the Standard Model. Currently, LHC experiments have stronger bounds on operators leading to spin-dependent scattering than direct detection experiments, while direct detection probes are more constraining for spin-independent scattering for WIMP masses above a few GeV.

This work provides an overview on the current status of phenomenology and searches for heavy vector-like quarks, which are predicted in many models of new physics beyond the Standard Model. Searches at Tevatron and at the LHC, here listed and shortly described, have not found any evidence for new heavy fermionic states (either chiral or vector-like) and have therefore posed strong bounds on their masses: depending on specific assumptions on the interactions and on the observed final state, vector-like quarks with masses up to roughly 400–600 GeV have been excluded by all experiments. In order to be as simple and model independent as possible, the chosen framework for the phenomenological analysis is an effective model with the addition of a vector-like quark representation (singlet, doublet, or triplet underSU(2)L) which couples through Yukawa interactions with all SM families. The relevance of different observables for the determination of bounds on mixing parameters is then discussed and a complete overview of possible two body final states for every vector-like quark is provided, including their subsequent decay into SM particles. A list and short description of phenomenological analyses present in the literature are also provided for reference purposes.

We study the production of a light top-squark pair in association with the lightest Higgs boson [Formula: see text], as predicted by the Next-to-Minimal Supersymmetric Standard Model (NMSSM) in proton–proton collisions at center-of-mass energies of 13 TeV and 33 TeV. We scan randomly about 10 million points of the NMSSM parameter space, allowing all possible decays of the lightest top-squark and lightest Higgs boson, with no further assumptions, except for known physical constraints such as perturbative bounds, dark matter relic density consistent with recent Planck experiment measurements, Higgs mass bounds on the next to lightest Higgs boson, [Formula: see text], assuming it is consistent with LHC measurements for the Standard Model Higgs boson, LEP bounds for the chargino mass and [Formula: see text] invisible width, experimental bounds on [Formula: see text] meson rare decays and some LHC experimental bounds on SUSY particle spectra different to the particles involved in our analysis. We find that for low mass top-squark, the dominating decay mode is [Formula: see text] with [Formula: see text]. We use three benchmark points with the highest cross-sections, which naturally fall within the compressed spectra of the top-squark, and make a phenomenological analysis to determine the optimal event selection that maximizes the signal significance over backgrounds. We focus on the leptonic decays of both [Formula: see text]’s and the decay of the lightest Higgs boson into [Formula: see text]-quarks [Formula: see text]. Our results show that the high luminosity LHC will have limitations to observe the studied SUSY scenario and only a proton collider with a collision energy above 33 TeV will be able to observe this signal with more than three standard deviations over background, albeit for stop masses below 300 GeV.

In this paper, we study the sensitivity of the fraction of [Formula: see text] events arising from gluon–gluon fusion to the chromoelectric and chromomagnetic dipole moments (CEDM and CMDM) as well as the total and differential [Formula: see text] cross-sections at the LHC and Tevatron. The sensitivity of measured charged asymmetry at the LHC to CEDM and CMDM is also studied. We find that at the Tevatron and the LHC, nonzero values of CMDM could suppress the [Formula: see text] production rate. It is shown that the ratio of [Formula: see text] at the Tevatron is more sensitive to CEDM and CMDM than the LHC case. The presence of CEDM always increases the contribution of gluon–gluon fusion process in top pair rate at the Tevatron and LHC. Except for a small range of CMDM, the presence of CEDM and CMDM can increase the fraction of gluon–gluon fusion at the Tevatron and LHC. The measured ratio of [Formula: see text] at the Tevatron is used to derive bounds on the chromoelectric and chromomagnetic dipole moments as well as the total and differential [Formula: see text] cross-sections at the LHC and Tevatron, and the measured charged asymmetry at the LHC. The combination of [Formula: see text] and σ LHC provides stringent limits on CMDM and CEDM.

Afin de subvenir aux besoins d'assainissement des cours d'eau, le Québec s'est doté de stations d'épuration, capables de subvenir aux besoins domestiques de l'ensemble des habitants. Ainsi, les eaux usées passent par une station d'épuration avant d'être retournées vers le milieu naturel, ceci afin de préserver la faune et la flore aquatiques des cours d'eau. Malheureusement, une solution peut parfois créer un nouveau problème: une fois les eaux traitées, que faire des boues d'épuration ? Avec le nombre grandissant de stations d'épuration mises en service, les estimations montrent qu'en l'an 2 000, il y aura une production, par la totalité des stations du Québec, d'environ 180 000 tonnes de matières sèches par an. Dans le cas des boues d'épuration, la valorisation agricole semble être une solution de recyclage, qui permette de diminuer le stock de boue et qui puisse en même temps, aider les cultures par la fertilisation du sol. La localisation de sites, susceptibles de recevoir des boues, fait intervenir un grand nombre de facteurs, qui sont aussi divers que: la nature du sol, la distance par rapport à des habitations ou le kilométrage à faire par les camions lors de l'épandage. Afin d'intégrer l'ensemble de ces facteurs, le projet STOPER, fait appel à un système d'information géographique ARC/INFO, dans le but de cartographier les contraintes biophysiques à respecter pour l'épandage. Cet outil, dynamique et visuel, devrait fournir la possibilité, à une municipalité, de devenir autonome, pour la gestion de ses déchets. En fonction des renseignements fournis, le responsable pourra examiner les possibilités et sélectionner certains sites. Grâce à un ensemble de processus, cet outil cartographique permet de produire une information pertinente en vue d'une prise de décision et de gestion des boues.

À partir des années 1980, la recherche de nouveaux traitements des déchets de toutes sortes est devenu un objectif primordial pour la société. Les boues d'usines d'épuration des eaux usées constituent l'un de ces déchets qui peut aujourd'hui être recyclé à cause de sa valeur fertilisante. Présentement, la ville de Lac-Mégantic a le choix entre plusieurs solutions pour la gestion des boues, comme l'enfouissement, la valorisation, l'incinération et le compostage. Dans ce travail, nous nous limiterons à l'évaluation de l'enfouissement et de la valorisation des boues. D'une part, nous parlerons de l'enfouissement qui semble le mode de gestion des boues le plus fréquemment utilisé, quoique cela provoque un manque d'espace au site d'enfouissement et amène également l'élimination d'un facteur de production. D'autre part, nous parlerons des boues qui peuvent être utilisées en agriculture comme engrais. En effet, on reconnaît aux boues des usines d'épuration une valeur fertilisante des sols riche en minéraux essentiels pour la croissance des plantes. Par contre, la valorisation des boues suscite des interrogations en ce qui a trait à la teneur en métaux lourds et à son niveau de pathogènes (voir annexe B). Les nouvelles techniques de valorisation des boues tel le chaulage et les législations reconnues représentent cependant des moyens d'incorporer les boues au cycle d'alimentation avec plus d'assurance. La société doit faire un choix entre l'enfouissement et la valorisation, deux méthodes qui ont chacune leurs avantages et leurs inconvénients. Le problème d'insuffisance d'espace pour l'enfouissement des déchets et des boues, la contamination inévitable des sols poussent les décideurs à envisager des solutions moins polluantes pour la suppression des déchets, notamment les boues. Mais, cette solution est-elle vraiment la meilleure? L'utilisation des boues pour des fins de valorisation agricole n'est pas une solution sans impact, car disposer des boues sur les terres agricoles pourrait contaminer la chaîne alimentaire humaine. Quelle est la méthode la plus avantageuse pour la société? L'analyse avantages-coûts peut aider à répondre à cette question en mettant en relief les différentes caractéristiques de l'élimination des boues de chaque option technologique. Cette analyse permet non seulement de calculer les coûts et bénéfices engendrés par la gestion des boues pour la municipalité, mais aussi les coûts et avantages d'une telle gestion pour la société en général et, dans le cas de la gestion des boues, pour les agriculteurs qui pourraient être impliqués par le biais de l'épandage des boues sur les terres agricoles. L'objectif immédiat de ce mémoire est d'évaluer en terme monétaire les avantages et les coûts sociaux de la valorisation agricole des boues de l'usine d'épuration des eaux de Lac-Mégantic et ceux de leur enfouissement. L'élaboration de ce protocole permettra d'intégrer des indicateurs économiques dans le modèle STOPER et plus particulièrement par l'entremise du projet intégrateur de Lac-Mégantic. Dans la première partie de cette analyse, nous situerons les solutions pour la ville de Lac-Mégantic à l'intérieur de l'analyse bénéfices-coûts. Nous verrons principalement: la valeur économique des boues; les enjeux pour la municipalité des deux solutions; et la situation de l'agriculteur face à l'esquisse de la valorisation qui prévaut pour lui. La deuxième étape de ce travail consistera à évaluer et à juger l'efficacité économique des deux projets (où préalablement les données auront été validées, vérifiées et calculées). À cette étape, nous allons comparer deux alternatives. D'abord, nous allons comparer un projet d'épandage des boues en été seulement et le statu quo (l'enfouissement). Dans un deuxième temps, nous ferons l'analyse de la valorisation agricole avec un site d'entreposage l'hiver par rapport à la valorisation estivale seulement. En troisième lieu, nous déterminerons si la condition de l'agriculteur est respectée dans le cas de la valorisation des boues. L'objectif de cet exercice est de déterminer la meilleure option pour la société. Par la suite, nous établirons une description sur les différents stades de l'évolution des boues (c.-à-d. les types de boues et leurs modes de transformation) et des impacts possibles au sens écologique (son effet sur l'écosystème) qu'on pourra retrouver à l'annexe A. Dans l'annexe B, le lecteur pourra retrouver des explications sur les composantes des boues, notamment sur les métaux lourds, les éléments nutritifs et les pathogènes.

L’objectif de ce mémoire est de reconstituer l’évolution des paléoenvironnements lacustres du Maghreb et du Sahara au cours du Quaternaire supérieur, à partir de diatomées. Deux secteurs géographiques sont étudiés : le Moyen Atlas (Maroc) et l'Aïr (Niger) En première partie, on retrace les bases de la reconstruction des paléoenvironnements à partir des diatomées. L’écologie des espèces et des assemblages de diatomées rencontrés dans les séquences lacustres étudiées est présentée, à partir des références actuelles régionales et/ ou des données bibliographiques. La seconde partie reconstitue la paléohydrologie et la paléoclimatologie du Moyen Atlas. L'étude de 2 sondages (marginal et central) du lac Tigalmamine fait ressortir les faits majeurs ci-dessous : entre 18 et 16 ka B. P. , les marges du lac actuel sont occupées par des marécages reflétant un environnement vraisemblablement plus frais que l'actuel. Entre 16 et 9 ka B. P. , une phase lacustre de faible profondeur aux eaux douces A oligosalines est enregistrée. Cette phase est toutefois interrompue vers 12 ka B. P. Par un stade sec, et peut être froid. Un lac profond d’eau oligotrophe et douce caractérise la période 9-8. 5 ka B. P. -Actuel, malgré des régressions passagères vers 7. 3-6. 8 ka et 3. 5 ka B. P. . La troisième partie traite des diatomées des paléolacs de l'Aïr. La dépression de l'Adrar Bous était occupée par une plaine d’innondation vers 88 ka B. P. . Entre 20 ? et 14 ? ka B. P. , une phase lacustre peu profonde est mise en évidence à Tin Ouaffadène. Dans les deux sites, un lac profond d’eau douce s’installe entre 10 et 7. 5 ka B. P. . Vers 9. 3-9 ka B. P. , une phase régressive est ressentie dans les deux dépressionsThis work attemps to reconstruct the evolution of the lacustrine palaeoenvironments in the Maghreb and the Sahara during the late Quaternary, by using diatoms. Two geographical sectors are investigated : the Middle Atlas (Morocco), and the Aïr (Niger). In the first part, the background of palaeoenvironmental recontructions based on diatoms are presented. Ecological data on the investigated species and assemblages encountered in the late Quaternary lacustrine sequences (lake Tigalmamine, Middle Atlas; Tin Ouaffadene and Adrar Bous, Aïr) are derived from modern regiôhal references, and/or from literature. The second part reconstitutes the lake Tigalmamine paleohydrology and paleoclimatology since 18 ka B. P. . The marginal and central cores analysis provides the major following conclusions: from 18 to 16. 3 ka B. P. Swampy, cool environments. From 16 to 9 ka B. P. A shallow, freshwater lake has experienced regression (swampy, cool environments)at about 12 ka B. P. . The reestablishment of stable humid conditions occurred at about 9-8. 5 ka B. P. . However brief regressions are registered around 7. 3-6. 8 ka and 3. 5 ka B. P. . The third part deals with the Tin Ouaffadene and Adrar Bous basins. A flood plain environment is recorded at Adrar Bous at about 88 ka B. P. . A shallow late Pleistocene lake (20-14 ka B. P. ?) is described in Tin Ouaffadene. Freshwater, eutrophic lakes occupied the two depressions from about 10 to 7. 5 ka B. P. . In conclusion, the. Reestablishment of generally humid conditions at the Holocene occured at about 9-8. 5 ka RP. In the Maghreb, and at about 10 ka B. P. In the Sahara

Since the famous discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012, the field of elementary particle physics has been at an impasse. Ever more precise measurements of the particle's properties have served only to verify the predictions of the current prevalent theory - the Standard Model (SM) of particle physics - even though this theory is known to be incomplete. However, the SM is only able to properly describe the observed boson with an incredibly unnatural finetuning of its parameters, which has led many to propose alternative models that can more naturally accommodate the particle in the hope of establishing a more complete theory. We concern ourselves in this work with one class of such models, in which the Higgs boson is not an elementary particle as is assumed by the SM, but rather a bound state of some as-yet undiscovered strong dynamics. We give a pedagogical introduction to the theory of such composite Higgs models (CHMs), and provide a complete description of three different versions of the Two-Site Minimal 4D CHM - the simplest calculable extensions of the SM in which the Higgs boson is composite, based on the SO(5) ! SO(4) symmetry breaking pattern - that differ in their fermion sector embeddings. Convergent global fits are performed on these three models, under both frequentist and Bayesian frameworks, in order to end the regions of their parameter spaces that best fit a wide range of constraints, including recent Higgs measurements and exclusion bounds on heavy resonance production from Run II of the LHC. We use a novel technique to analyse the finetuning of the models, quantifying the tuning as the Kullback-Leibler divergence from the prior to the posterior probability on the parameter space. Each model is found to be able to satisfy all constraints at the 3 level simultaneously, but the model that has fermions embedded in the fundamental representation of SO(5), despite suffering from a \double tuning", is clearly favoured by a Bayesian model comparison. As a by-product of the fits, we analyse the collider phenomenology of our models in these viable regions. We find clear predictions of the minimally-tuned models that the gg ! H ! cross section is less than -90% that predicted by the SM, which is already in slight tension with experiment and could potentially be ruled out in the future high-luminosity run of the LHC. In addition, the lightest fermions F arising from the new strong dynamics in these models are seen in general to lie between -1:1 TeV and -3:0 TeV, with the F -> tW+ and F ->bW+ decays offering particularly promising channels for probing these models in future collider searches.Thesis (Ph.D.) -- University of Adelaide, School of Physics, 2020

The ALICE detector system has excellent particle identification (PID) capabilities employing a variety of techniques. One of these is the specific energy loss dE/dx measurement in the Time Projection Chamber (TPC). The dE/dx is different for each particle species and can be used to identify charged particles including also (anti-)nuclei. The time-of-flight method uses the m^2/z^2 distributions (m = mass of the particle, z charge number of the particle), which are determined from the flight time and the length of the particle trajectory measured with the Time-Of-Flight (TOF) detector, and the momentum extracted through combined tracking in the ALICE setup in the mid-rapidity region.
Within this doctoral thesis these techniques are used for the search for two exotic bound states, the anti-Λn bound state and the H-dibaryon, as well as for the measurement of the production yield per unit of rapidity dN/dy of alpha and anti-alpha particles. Both, the searches for the exotica and the measurement of the (anti-)alpha, are performed on data from Pb–Pb collisions at sqrt(s_(NN)) = 2.76 TeV.
The searches for the two investigated exotica are carried out in the decay channel anti-Λn → anti-d + π+ and H → Λ+p+π−. The different decay products are identified using the specific energy loss measurements in the TPC and their invariant mass is determined. For both investigated bound states no signals are observed in the resulting invariant mass distributions. Therefore, upper limits on the production rates are estimated for eight different assumed lifetimes between 4 cm and 3 m. In addition, the upper limits are determined independent of the branching ratio of the investigated decay channel and are compared to different theory predictions.
The alpha particle is the heaviest nucleus produced and detected during ultra-relativistic heavy-ion collisions at LHC energies and the anti-alpha is even the heaviest anti-nucleus observed so far at all. The particles are identified using the dE/dx measurement in the TPC and the m^2/z^2 distributions determined with the measurements of the TOF. The efficiency × acceptance is determined using a Monte Carlo production. As the observed statistics does not allow for the determination of the transverse momentum pT-spectrum, a Blast-Wave extrapolation is used, which is based on the measurements of the spectra of deuterons and 3He. This allows for the pT-integrated determination of the efficiency. Systematic uncertainties are calculated and the resulting rapidity density dN/dy is comparable with the prediction from a thermal model.

This essay argues that we need to give more thought to sex in Hamlet—to broaden our thinking beyond the critical consensus regarding the protagonist’s “loathing” of sexuality. I suggest that Hamlet’s antisexual disposition is part not only of his investment in a bounded, isolated self, but also of his concomitant bias toward an epistemology that figures knowledge under the sign of possessive dominion. This means that we can apprehend sex philosophically (and philosophy sexually). This essay understands sex, following Jean-Luc Nancy, as an invitation to unknow, to let go of the sovereignty we habitually impose upon things, experiences, bodies. For most of the play, Hamlet turns down that invitation. But sex isn’t purely degraded in the play; Hamlet suggests a different relation to self-sovereignty and bodily closure, one that embraces both the impossibility of sovereign selfhood and, paradoxically, the prospect that one’s very existence is staked upon this impossibility.

Originally formulated in the context of biological studies, the Life cycle (LC) concept was and now has become widely adopted as a framework for the interpretation and evaluation of phenomena that are subject to, and bound by the inevitability of change. The application of the LC concept to the development of industrial products is an important element in the administration of technological innovation. On this basis, therefore, it is referred to as the product life cycle (PLC). The concept of the PLC is used to support decision making in the management of product development. It may also be used in corporate strategy development, as well as the planning of activities and can be adapted to focus on technology deployment.

Kraepelin described one of the core features of schizophrenia to be its progressively worsening course with little chance of recovery. In contrast, mood disorders were thought to have an episodic course with good functioning between bouts of mania and depression, and a relatively good outcome. The ensuing decades of research have painted a more complex picture of the course and outcome of schizophrenia. Most notably, in contrast to Kraepelin’s bleak outlook, a fair number of individuals can more or less successfully recover from schizophrenia. Dr Manfred Bleuler, son of Dr Eugen Bleuler, reported a 20- year follow-up of over 200 individuals with schizophrenia excluding those who had either died or shown little psychiatric stability over the previous 5 years. Bleuler noted that one in five patients had recovered to normal levels of social functioning and were free of psychotic symptoms. Furthermore, one in three patients had a relatively good outcome. Thus, while patients still experienced hallucinations and delusions, they showed only mild problems in social functioning and very few visible behavioural problems. These results are quite remarkable given that the study was completed prior to the discovery of antipsychotic medications.Dr Luc Ciompi was able to follow nearly 300 patients for as long as 50 years after hospitalization. Using Bleuler’s categories of outcome, Ciompi found 27% of the patients to be fully recovered, 22% to have mild symptoms, 24% to have moderately severe symptoms, and 18% to have severe symptoms. Nine per cent of the sample had an uncertain outcome. A progressively worsening, gradual, and serious onset was seen in about half of the affected individuals, while a sudden or acute onset of illness with little or no problems in premorbid functioning was found for the rest of the sample. About half of the individuals with schizophrenia had a continuous course of illness, and the remainder had an episodic course. In addition, an episodic course was more likely among patients with acute onset. Acute onset and episodic course were both associated with better long- term outcome.A study performed by Dr Ming Tsuang and team, known as the Iowa 500 study, followed 186 individuals with schizophrenia, 86 with bipolar disorder, and 212 with major depressive disorder for 35– 40 years.

Software metrics provide basic means to quantify several quality aspects of information systems. However, the effectiveness of the measurement process is directly dependent on the definition of reliable thresholds. To define appropriate thresholds, we need to consider characteristics of the information systems, such as their size and domain. There are several studies to propose methods to derive thresholds and evaluate them. However, we still lack empirical knowledge about whether and how thresholds vary across different information system domains. To tackle this limitation, this paper investigates specific thresholds in four information system domains: accounting, e-commerce, health, and restaurant. Our study relies on 40 information systems to derive domain-specific thresholds for 9 well-known software metrics. Our results indicate that lower-bound thresholds (e.g., 15% smaller classes) usually do not significantly vary across domains. However, for all analyzed metrics, upper-bound thresholds (e.g., 5% largest classes) are different in some domains. Moreover, our study also suggests that domain-specific thresholds are more appropriated than generic ones. For instance, we observed in our analysis that the more appropriated threshold to select the 5% largest classes is 290 LOC in health systems and 147 LOC in accounting systems.

In recent years, renewable energy technologies have received increasing attention. However, the constant availability of renewable energies is not predictable, so that technologies for excess energy storage become increasingly important. One possibility for the technical implementation of such a storage technology is to bind hydrogen, produced using this excess energy, to liquid organic compounds, so-called Liquid Organic Hydrogen Carriers (LOHC), where hydrogen is bound to a H2-lean LOHC molecule in an exothermal hydrogenation reaction. The dehydrogenation process releases the stored hydrogen in an endothermal reaction. This technology offers advantages such as storage and transport safety, along with the high energy density. LOHC systems can assist in the realization of future distributed energy supply networks, as well. Micro gas turbines (MGT) play an important role in distributed energy supply, so that the coupling of a hydrogen fueled MGT with a reactor for the dehydrogenation process is a desirable achievement. In such a combined system, the excess exhaust enthalpy can be used to maintain the endothermal dehydrogenation reaction without affecting the overall efficiency of the gas turbine. This paper investigates the feasibility of a direct coupling between a hydrogen fueled recuperated micro gas turbine and the dehydrogenation process using the excess exhaust heat. For this purpose, a numerical simulation based on energy balances and thermodynamic equilibrium is implemented to model the process. Primary criteria for the evaluation of the process feasibility are the MGTs exhaust gas temperature, the exhaust gas mass flow rate, and the LOHC mass flow rate through the dehydrogenation unit. These three parameters specify the mass flow rate of LOHC, which can be dehydrogenated and thus, the mass flow rate of released hydrogen. Using the implemented numerical model, the suitability of two different LOHCs, N-Ethylcarbazole and an industrial heat transfer oil is investigated at two different pressure levels with respect to thermodynamic feasibility and process efficiency. The results show that the usable excess enthalpy in the exhaust gas of the investigated Turbec T100 MGT is sufficient to release enough hydrogen for re-use as fuel in the micro turbine process for three of the four investigated cases.

The General Electric Company has developed and successfully tested a full-scale, ‘F’ class (2550°F combustor exit temperature), rich-quench-lean (RQL) gas turbine combustor, designated RQL2, for low heating value (LHV) fuel and integrated gasification combined cycle applications. Although the primary objective of this effort was to develop an RQL combustor with lower conversion of fuel bound nitrogen to NOx than a conventional gas turbine combustor, the RQL2 design can be readily adapted to natural gas and liquid fuel combustion. RQL2 is the culmination of a 5 year research and development effort that began with natural gas tests of a 2″ diameter perforated plate combustor and included LHV fuel tests of RQL1, a reduced scale (6″ diameter) gas turbine combustor. The RQL2 combustor includes a 14″ diameter converging rich stage liner, an impingement cooled 7″ diameter radially-stratified-quench stage, and a backward facing step at the entrance to a 10″ diameter film cooled lean stage. The rich stage combustor liner has a novel double-walled structure with narrow circumferential cooling channels to maintain metal wall temperatures within design limits. Provisions were made to allow independent control of the air supplied to the rich and quench/lean stages. RQL2 has been fired for almost 100 hours with LHV fuel supplied by a pilot scale coal gasification and high temperature desulfurization system. At the optimum rich stage equivalence ratio NOx emissions were about 50 ppmv (on a dry, 15% O2 basis), more than a factor of 3 lower than expected from a conventional diffusion flame combustor burning the same fuel. With 4600 ppmv NH3 in the LHV fuel, this corresponds to a conversion of NH3 to NOx of about 5%. As conditions were shifted away from the optimum, RQL2 NOx emissions gradually increased until they were comparable to a standard combustor. A chemical kinetic model of RQL2, constructed from a series of ideal chemical reactors, matched the measured NOx emissions fairly well. The CO emissions were between 5 and 30 ppmv (on a dry, 15% O2 basis) under all conditions.

Life cycle cost analyses (LCC/A) have not typically been used for pavement optioneering for nearly 30 years in Australia, nor are they generally required in detailed design. To date, asphalt pavements were assumed to have lower construction costs but acknowledged as requiring regular maintenance (every 5 to 10 years), whereas concrete is well known to require less maintenance (typically at intervals of 10 to 20 years). Concrete is therefore characterised as being lower cost only in terms of its life cycle and consequently overlooked where construction costs are the focus of pavement options evaluation. However, with significant recent changes in road construction materials and processes, preconceptions around life cycle costs of asphalt and concrete pavements around the world should be reviewed. This paper reports on the findings of a study conducted by Arcadis which compared the life cycle costs of highway low- noise high-speed pavements - plain concrete (PCP), full depth asphalt (FDA) and asphalt over heavily bound (ACH). The study compared LCC of these pavements across a range of project- specific scenarios (resource availability, site complexity and traffic constraints) in addition to the impact of adopting international discount rates. With a new generation of pavement renewal now commencing in Australia (45 years after the first), this work also examined the viability of prolonging the service life of pavements in relation to its impact on life cycle costs, closures and environmental impact. This paper ultimately concludes best value of the various pavement scenario combinations by ranking and comparing all pavements options, and makes recommendations for future life cycle assessments.

Traditionally tolerances for manufactured parts are specified using symbolic schemes as per ASME or ISO standards. To use these tolerance specifications in computerized tolerance synthesis and analysis, we need information models to represent the tolerances. Tolerance specifications could be modeled as a class with its attributes and methods [ROY01]. Tolerances impose restrictions on the possible deviation of features from its nominal size/shape. These variations of shape/size of a feature could be modeled as deviation of a set of generalized coordinates defined at some convenient point on the feature [BAL98]. In this paper, we present a method for converting tolerance specifications as per MMC (Maximum Material Condition) / LMC (Least Material Condition) / RFS (Regardless of Feature Size) material conditions for standard mating features (planar, cylindrical, and spherical) into a set of inequalities in a deviation space for representation of deviation of a feature from it’s nominal shape. We have used the virtual condition boundaries (VCB) as well as tolerance zones (as the case may be) for these mappings. For the planar feature, these relations are linear and the bounded space is diamond shaped. For the other cases, the mapping is a set of nonlinear inequalities. The mapping transforms the tolerance specifications into a generalized coordinate frame as a set of inequalities. These are useful in tolerance synthesis, and analysis as well as in assemblability analysis in the generalized coordinate system (deviation space). In this paper, we also illustrate the mapping procedures with an example.
