Modelling and optimising micro-nozzle resin injection repair of impacted composites using CFD
Creators: name: Asiliskender, Ahmed
Publisher: name: Imperial College London
Year: 2023

description: Resin injection repair is identified to have a gap of knowledge and rigour in the modelling and execution of the process. We outline the strategy of our proposed predictive modelling strategy of ‘reconstruction-simulation-injection’ to simulate real cases to improve repair outcomes. We model the damage zone using Darcy’s law and determine permeability using two methods applied on the Kozeny-Carman equation. We then discuss how we evaluate porosity and detail two proposed methods on reconstructing the porosity field. We verify the model through simulation, and demonstrate verification using a novel comprehensive 2D porosity liquid-ideal gas phase flow model after deriving the analytical solution, which is a contribution of our work. Next, we apply the now-established model to reconstruct real damage cases using the two methods and compare them. We also calibrate the permeability parameter for the model by comparison to a simulation accuracy index, and also calibrate an ultrasonic scanning parameter to minimise reconstruction artefacts as well as the sensitivity of the reconstructed geometry characteristics to scan parameter variations. Then, we validate the model by simulating real repair cases and comparing them to the experimental outcomes, achieving simulation accuracy indices of about 70% or more. We demonstrate the application of the resin injection model by applying resin injection in a proof-of-concept simulation and use it for a case study, and examine the importance of hole configuration, vacuum usage as well as resin flow behaviour between inlet and outlet holes in the context of a given damage area geometry. It is important to maximise the total length of resin flow paths available, through carefully placing inlet and outlet holes, to allow resin to infiltrate the damage zone as much as possible. Vacuum increases the minimum achievable filling, and it is still invariably better to use vacuum with an optimal hole placement, instead of one or the other. In a second case study, we improve the predicted outcome by the model after intentionally changing the hole configuration to maximise resin infiltration, demonstrating that filling can be improved by placing holes intelligently (e.g. by using gathered information on the damage area, together with knowledge of how resin would flow). Using this, we conduct an optimisation study of the resin injection model by first setting up the optimisation strategy and carefully determining the methodology. The optimisation procedure is verified by using one and two degree-of-freedom optimisation cases, with known optima. Then, the optimisation strategy is applied to reconstructed repair cases to demonstrate and assess the efficacy of the optimisation procedure, with average reductions in unfilled volumes of approximately 28% compared to initial configurations.

description: Let $K$ be a number field, let $S$ be a finite set of places of $K$ containing the archimedean places and let $μ$, $α_1,α_2,α_3$ be non--zero elements in $K$. Denote by $\OS$ the ring of $S$--integers in $K$ and by $\OS^\times$ the group of $S$--units. Then the set of equivalence classes (namely, up to multiplication by $S$--units) of the solutions $(x,y,z,\varepsilon_1, \varepsilon_2,\varepsilon_3,\varepsilon)\in\OS^3\times(\OS^\times)^4$ of the diophantine equation $$ (X-α_1 E_1 Y) (X-α_2E_2 Y) (X-α_3E_3 Y)Z=μE, $$ satisfying $\Card\{α_1\varepsilon_1,α_2\varepsilon_2,α_3\varepsilon_3\}= 3$, is finite. With the help of this last result, we exhibit new families of Thue-Mahler equations having only trivial solutions. Furthermore, we produce an effective upper bound for the number of these solutions. The proofs of this paper rest heavily on Schmidt's subspace theorem.
Investigating the protein subcomplexes from a conjugative Type IV Secretion System
Creators: name: Amin, Himani
Publisher: name: Imperial College London
Year: 2023

description: Type IV secretion system (T4SS) are versatile nanomachines that enable the efficient transport of substrates in bacteria. In general, they are formed from two major membrane embedded subassemblies: an outer membrane core complex (OMCC) and an inner membrane complex (IMC). The conjugative T4SS encoded by the F plasmid is of particular interest due to its clinical relevance as it facilitates the spread of antibiotic resistance amongst bacterial population. Despite its importance, atomic details of the F-T4SS structure and protein-protein interactions were rudimentary which in turn precludes thorough understanding of how conjugation is orchestrated. Therefore, this thesis aimed to improve knowledge on the F-T4SS by studying the structure of the F-OMCC and investigating other proteins the complex may interact with. After optimising the detergent solubilisation of the F-OMCC expressed from the pED208 F-like plasmid, and improving the purification of the complex, a cryo-EM dataset was collected. Using single particle analysis, the structure was solved with an overall resolution of 3.3 Å. The F-OMCC is formed from two concentric rings which have two distinct symmetries. The outer ring adopts 13-fold symmetry whereas the inner ring showed 17-fold symmetry, together they form a 2.1 MDa complex. The atomic models of TraB, TraK and TraV were built into the structure, and they revealed a unique stoichiometric arrangement. Interestingly, TraV and TraK proteins were found to adopt two different conformations within the outer ring. TraV and TraB were found to accommodate the symmetry mismatch by existing in both F-OMCC rings, and also appeared to confer flexibility. This makes the F-OMCC a dynamic complex which is likely to have important implications in the pilus and T4SS activity during conjugation. The interactions between the F-OMCC and other Tra/Trb proteins were also investigated to decipher how the concerted dynamics of the pilus may be connected to the complex. A potential interaction between F-OMCC and the proteins TraH and TraN was observed by pull-down assays. Furthermore, initial work on TraG found that it seems to assemble as a high order oligomer in solution. The results are reminiscent of a hexameric protein which may be functionally important. Together, the findings of this thesis reveal novel insights into the F-T4SS and its subassemblies. The approach used to purify the F-OMCC and study the interactions will act as the basis of future work on the F-T4SS and is directly applicable to the other protein complexes within the conjugative nanomachine.

description: Partially-observed data collected by sampling methods is often being studied to obtain the characteristics of information diffusion networks. However, these methods usually do not consider the behavior of diffusion process. In this paper, we propose a novel two-step (sampling/estimation) measurement framework by utilizing the diffusion process characteristics. To this end, we propose a link-tracing based sampling design which uses the infection times as local information without any knowledge about the latent structure of diffusion network. To correct the bias of sampled data, we introduce three estimators for different categories; link-based, node-based, and cascade-based. To the best of our knowledge, this is the first attempt to introduce a complete measurement framework for diffusion networks. We also show that the estimator plays an important role in correcting the bias of sampling from diffusion networks. Our comprehensive empirical analysis over large synthetic and real datasets demonstrates that in average, the proposed framework outperforms the common BFS and RW sampling methods in terms of link-based characteristics by about 37% and 35%, respectively.

description: The Economic and Food Safety Authority (ASAE) has in place a National Sampling Plan, “PNCA- Plano Nacional de Colheitas de Amostras”, targeted at retail. This plan aims to control the safety of foodstuffs, on a risk basis and with appropriate frequency, with regard to hazards set in Reg. (EC) No. 2073/2005, Reg. (EC) No. 1881/2006, Reg (EC) No. 1333/2008 and allergens according to Reg. (EU) No. 1169/2011, and to verify specific legal requirements for certain foodstuffs. PNCA is a risk-based official food monitoring control plan, that takes into account the risk associated with food, the non-compliance rate of previous years, the analytical capacity to detect the hazard and, nowadays, the national food consumption data. The sampling frequencies by food group are designed based on the combination of two methodologies, Composite Risk Matrix (qualitative risk level classification) and Priority Risk Number (quantitative risk level classification) as described is this document.

The result is an exact integral equation which can be solved numerically by the method of iteration to arbitrary precision. We compare predictions for the shear and bulk viscosities of a massive system with those obtained from the exact solution. Finally, we compare the time evolution of the bulk pressure obtained from our exact solution with results obtained from the dynamical equations of second-order viscous hydrodynamics.

Compact planetary systems perturbed by an inclined companion: I. Vectorial representation of the secular model
Creators: name: Boué, Gwenaël

Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The non-resonant secular dynamics of compact planetary systems are modeled by a perturbing function which is usually expanded in eccentricity and absolute inclination with respect to the invariant plane. Here, the expressions are given in a vectorial form which naturally leads to an expansion in eccentricity and mutual inclination. The two approaches are equivalent in most cases, but the vectorial one is specially designed for those where a quasi-coplanar system tilts as a whole by a large amount. Moreover, the vectorial expressions of the Hamiltonian and of the equations of motion are slightly simpler than those given in terms of the usual elliptical elements. We also provide the secular perturbing function in vectorial form expanded in semimajor axis ratio allowing for arbitrary eccentricities and inclinations. The interaction between the equatorial bulge of a central star and its planets is also provided, as is the relativistic periapse precession of any planet induced by the central star. We illustrate the use of this representation for following the secular oscillations of the terrestrial planets of the solar system, and for Kozai cycles as may take place in exoplanetary systems.

subject: Resistance (Philosophy)

description: Recent research in the field of resistance studies has called for the rethinking of the concept of resistance and the overcoming of paradigmatic distinctions between everyday tactics and the contentious politics of social mobilisation. By drawing on Marxist and post-Marxist political thought, this thesis will contribute to such attempts by proposing an ontology of political action and a conception of resistance that promises to bridge the gap between everyday tactics and collective and organised attempts to resist power. Traditionally, resistance and counter-hegemonic political action are understood as requiring a strategic, collective and organised mobilisation of activists, who directly oppose power and seek to introduce social change through the successful achievement of pre-defined demands. Drawing on the works of Lev Tolstoy, Mahatma Gandhi, and on Walter Benjamin’s concept of divine violence, the first part of this thesis will propose a contrasting ontology of political action as affirmative passivity, a type of nonviolent political praxis that involves the performative refusal to engage in everyday actions and activities. Such a conception of political action authorises a mode of resistance that does not directly oppose what it attempts to resist, but rather subverts power and leads to social change through passive individual withdrawal and cessation of activity. The second part of this thesis will turn to the political projects of Slavoj Žižek and Giorgio Agamben to trace and reconstruct affirmative passivity from their proposed “Bartleby” politics. It will be argued that both versions of Bartlebian politics authorise a conception of resistance that transgresses the dichotomy between everyday and collective forms of resistance. The thesis will critically evaluate these two authors’ takes on Bartleby politics, how they differ based on their distinct readings of Benjamin’s “divine violence” and Hegel’s concept of sublation and assess the implications of the contrasting modes of everyday resistance that they enable.

description: A nationwide survey was conducted in March 1974 to measure consumer opinions concerning their satisfaction or dissatisfaction with food products, how these are sold in stores, and how well the food industry meets the consumer's demands. Questionnaires were completed by 1,831 households, or 72 percent of the eligible number in the sample. In each household, the person primarily responsible for food buying was interviewed. Generally, respondents expressed a high overall level of satisfaction with food products and foodstores. But probing beneath the surface unearthed several areas of frustration and dissatisfaction. Consumers evidently separate specific sources of dissatisfaction from their favorable overall evaluation of food products and stores. Price stood out as the most obvious source of displeasure but here too, the intensity of dissatisfaction differed significantly across products. Consumers also expressed dissatisfaction with the availability and reliability of product and shopping information. People most likely to be dissatisfied live in the Northeast, are less than 55 years old, have attended college, work outside the home, earn over $15,000 and live in the suburbs in larger households. Respondents generally were more satisfied with dairy products and eggs, bakery and cereal products, and processed fruits and vegetables than with convenience foods, fresh fruits and vegetables, and meat and poultry.

description: Opium / opium is one of the main plants in the manufacture of drugs which has the Latin name Papaver Somniferum which can cause dependence by giving a relaxing effect to a certain level until the user is unconscious. The historical method used in this research. This research proves that opium has been a monopoly merchandise of the Verenigde Oost-Indische Compagnie since the 1650s, and even this trading partnership formed the 'Societeyt van den Amphioen' or known as the Amphioen Foundation to handle the illegal opium sales. The East Indian Company under the British which controlled Bengkulu also formed the Bencoolen Opium Society in 1760 resembling a Dutch-formed foundation. The Amphioen Foundation was dissolved in 1794 which was replaced by an opium pacht with a system of trade rights auction which resulted in the emergence of toll booths under Chinese traders during the 1820s decade. The Nederlandsche Handels Maatschappij company belonging to the Kingdom of the Netherlands then took over all the opium ships and obtained all the profits from large and small trade since 1827. The colonial government then implemented the opium regie in 1902 so that the opium trade was under the direct supervision of the Ministry of Finance of the Dutch East Indies Government. The historical dynamics of opium in this period show that almost all systems implemented by Western nations are monopolistic, profit-oriented, and do not aim to reduce the consumption of opium.

description: Time-sharing Experiments for the Social Sciences (TESS) offers researchers the opportunity to capture the internal validity of experiments. Investigators submit proposals, and TESS fields successful proposals for free on a representative sample of adults in the United States. This experiment was conducted to explore how citizens recognize and respond to extremist beliefs. Respondents were asked to evaluate three profiles of hypothetical individuals in which the attributes of each individual are individually randomized (gender, race, the individual's partisanship, if most Democrats consider the individual extreme, if most Republicans consider the individual extreme, incivility, violation of various social norms, if the individual is politically engaged, and support for political violence, support for the rule of law). A total of 4,061 respondents participated. For each profile, respondents were asked to rate the individual’s extremism, indicate their willingness to vote for the individual in a local election and support for the individual being allowed to speak publicly or teach in public schools in the respondent’s community. This allowed for comparison of respondent judgments about extremism across group identity and the cues received from others.

description: We show that, in graphene with a small concentration of adatoms, the total magnetic moment $μ_T$ can be switched on and off by varying the Fermi energy $E_F$, either by applying a gate voltage or by suitable chemical doping. Our calculation is carried out using a simple tight-binding model described previously, combined with a mean-field treatment of the electron-electron interaction on the adatom. The values of $E_F$ at which the moment is turned on or off are controlled by the strength of the hopping between the graphene sheet and the adatom, the on-site energy of the adatom, and the strength of the electron-electron correlation energy U. Our result is in qualitatively consistent with recent experiments by Nair {\it et al.} [Nat.\ Commun.\ {\bf 4}, 2010 (2013)].

Publisher: name: Wiley Blackwell

description: Upscaling scenarios are indispensable elements of prospective life cycle assessment (LCA). However, current studies reveal confusing terminology and a wide range of approaches in this area. Therefore, we first defined the term upscaling scenario as the description of a possible future target stage of emerging technology, including the development pathway from a current stage within the course of research and development to this future stage. Second, we developed the novel systematic scheme UpFunMatLCA for generating explorative scenarios based on possible development pathways of the specific group of emerging functional material (FunMat)‐based energy technologies, including status quo developments. UpFunMatLCA represents a three‐step extension of conventional LCAs to upscale the life cycle inventory of emerging FunMats. UpFunMatLCA is based on a clear definition of a current status quo (conceptual, lab, or pilot stage) and a target matured (fab) development stage. A core part of UpFunMatLCA is the so‐called upscaling module, providing specific modeling methods and data for the upscaling of FunMats. Using perovskite solar cells, photovoltaic devices based on several FunMats and attached with great expectations regarding the future efficient provision of solar energy, we demonstrate the application of UpFunMatLCA, focusing on the upstream greenhouse gas (GHG) emissions of the prospective manufacturing. In the discussion, we point out the application area of UpFunMatLCA and the possible extension to depict further environmental impacts beyond GHG to contribute to the sustainability assessment of emerging technologies in the early stages of development.

description: Costs for a model California packinghouse for mature green tomatoes vary by packing technique employed. Assuming a constant 400-hour packing season and plant operating at 70 percent of maximum capacity (capacity equals 30 tons of fruit dumped per hour), costs may range from $3.56 to $3.82 per hundredweight of packable fruit. Lowest costs were achieved by using dry bin dumping, belt sizing for all fruit, automatic volume filling of No. 1 greens, and manual volume filling for vine-ripes. Highest costs were associated with a combination of trailer dumping, weight sizing, manual filling of No. 1 greens, and place packing of vine-ripes. Total investment for the model packinghouse using the least-cost combination of techniques was about $310,000 on a replacement cost basis. This included $27,500 for land and site preparation, $125,450 for buildings, and $155,700 for equipment.

As a result we obtained the anomalous dimensions of certain NS and Ramond fields. It turns out that the linear combination expressing the infrared limit of these fields in term of the IR theory SM_{p-2} is exactly the same as those of the nonsupersymmetric minimal theory.

description: We announce the discovery of a new Galactic companion found in data from the ESO VST ATLAS survey, and followed up with deep imaging on the 4m William Herschel Telescope. The satellite is located in the constellation of Crater (the Cup) at a distance of $\sim$ 170 kpc. Its half-light radius is $r_h=30$ pc and its luminosity is $M_V=-5.5$. The bulk of its stellar population is old and metal-poor. We would probably have classified the newly discovered satellite as an extended globular cluster were it not for the presence of a handful of Blue Loop stars and a sparsely populated Red Clump. The existence of the core helium burning population implies that star-formation occurred in Crater perhaps as recently as 400 Myr ago. No globular cluster has ever accomplished the feat of prolonging its star-formation by several Gyrs. Therefore, if our hypothesis that the blue bright stars in Crater are Blue Loop giants is correct, the new satellite should be classified as a dwarf galaxy with unusual properties. Note that only ten degrees to the North of Crater, two ultra-faint galaxies Leo IV and V orbit the Galaxy at approximately the same distance. This hints that all three satellites may once have been closely associated before falling together into the Milky Way halo.

description: Near the melting temperature, equilibrium bismuth melt is characterized by structural features that are absent in equilibrium monatomic simple liquids. In the present work, the structure of bismuth melt is studied by X-ray diffraction experiments and quantum chemical calculations. The presence of quasi-stable structures in the melt has been found, the lifetime of which exceeds the structural relaxation time of this melt. It is shown that these structures are characterized by a low degree of ordering and spatial localisation. It was found that up to $50$\% of the atoms in the melt can be involved in the formation of these structures. The elementary structural units of these structures are triplets of regular geometry with the characteristic lengths $3.25$ Å~and $4.7$ Å~as well as with the characteristic angles $45^{\circ}$ and $90^{\circ}$. The characteristic lengths of these triplets are fully consistent with correlation lengths associated with the short-range order in bismuth melt.

description: We control the diffusion of light in a disordered photonic waveguide by modulating the waveguide geometry. In a single waveguide of varying cross-section, the diffusion coefficient changes spatially in two dimensions due to localization effects. The intensity distribution inside the waveguide agrees to the prediction of the self-consistent theory of localization. Our work shows that wave diffusion can be efficiently manipulated without modifying the structural disorder.

Limits on Lorentz violation from charged-pion decay

Year: 2014

description: Charged-pion decay offers many opportunities to study Lorentz violation. Using an effective field theory approach, we study Lorentz violation in the lepton, W-boson, and quark sectors and derive the differential pion-decay rate, including muon polarization. Using coordinate redefinitions we are able to relate the first-generation quark sector, in which no bounds were previously reported, to the lepton and W-boson sector. This facilitates a tractable calculation, enabling us to place bounds on the level of $10^{-4}$ on first-generation quark parameters. Our expression for the pion-decay rate can be used to constrain Lorentz violation in future experiments.

description: Cascade seesaw mechanism generates neutrino mass at higher dimension (5+4n) operators through tree level diagram which bring the seesaw scale down to TeV and provide collider signatures within LHC reach. In particular, both Type-II scalar and Type-III heavy fermion seesaw signatures exist in such a scenario. Doubly charged scalar decays into diboson is dominant. We perform a thorough study on the LHC signals and the Standard Model background. We draw the conclusion that multilepton final state from interplay of doubly charged scalar and heavy fermion can provide distinguishable signatures from conventional seesaw mechanisms.

description: Background: Chronic Kidney Disease of unknown etiology (CKDu) is a heterogeneous disorder affecting kidney structure and its functions. CKDu has rapidly spread throughout Sri Lanka in the past two decades and has become predominant in the North Central Region. Food or water borne diseases are one of the key issues in food safety assurance in Sri Lanka. Pesticides and heavy metals play an important role in modern agriculture and food safety. Objective: To evaluate the toxic metal contamination status in the polished rice samples (BG 300) grown in the Maradankulama area. Methods: Maradankulama GN Division was selected based on the available information on medical/hospital records, which has the highest number of CKDu patients in the Mihintale Division as the sampling area. A survey protocol was also developed. Thirty polished rice samples (BG 300) were collected from the households subject to three paddy areas in the Maradankulama GN area according to the random stratified sampling method and heavy metal concentrations of rice samples (Chromium, Lead, Arsenic and Cadmium) were analyzed by ICP-MS. Results: The male CKDu patients were higher than females (Male, 57.15%; Female, 42.85%). All the CKDu patients subjected to the survey in the area belong to the farming community within the age group of 60-70 years. In Maradankulama Cr(7.268±0.046), Pb(1.923±0.209), As(0.064±0.009) and Cd(0.026±0.003) were detected in mg/kg levels. Among the analyzed metals in the rice samples, mean Cr and Pb contents have exceeded the maximum permissible level (MPL) according to the Codex Alimentarius commission guidelines. Conclusion: Arsenic and Cadmium contents in the rice samples were well below the Codex standard. However, rice samples have been contaminated with some nephrotoxic metals such as Chromium and Lead. Hence, long term exposure to the toxic metals may generate a risk for kidney damage in people.

Neural network as a tool for design of amorphous metal alloys with desired elastoplastic properties

description: The development and implementation of the methods for designing amorphous metal alloys with desired mechanical properties is one of the most promising areas of modern materials science. Here, the machine learning methods appear to be a suitable complement to empirical methods related to the synthesis and testing of amorphous alloys of various compositions. In the present work, it is proposed a method to determine amorphous metal alloys with mechanical properties closest to those required. More than $50\,000$ amorphous alloys of different compositions have been considered, and the Young's modulus $E$ and the yield strength $σ_{y}$ have been evaluated for them by the machine learning model trained on the fundamental physical properties of the chemical elements. Statistical treatment of the obtained results reveals that the fundamental physical properties of the chemical element with the largest mass fraction are the most significant factors, whose values correlate with the values of the mechanical properties of the alloys, in which this element is involved. It is shown that the values of the Young's modulus $E$ and the yield strength $σ_{y}$ are higher for amorphous alloys based on Cr, Fe, Co, Ni, Nb, Mo and W formed by the addition of semimetals (e.g. Be, B, Al, Sn), nonmetals (e.g. Si and P) and lanthanides (e.g. La and Gd) than for alloys of other compositions. Increasing the number of components in alloy from $2$ to $7$ and changing the mass fraction of chemical elements has no significantly impact on the strength characteristics $E$ and $σ_{y}$. Amorphous metal alloys with the most improved mechanical properties have been identified. In particular, such extremely high-strength alloys include Cr$_{80}$B$_{20}$ (among binary), Mo$_{60}$B$_{20}$W$_{20}$ (among ternary) and Cr$_{40}$B$_{20}$Nb$_{10}$Pd$_{10}$Ta$_{10}$Si$_{10}$ (among multicomponent).

description: The low-temperature transport properties (resistivity, thermal conductivity, thermoelectric power) are experimentally investigated for the compound YbMn2Sb2. Large Seebeck coefficient and nearly linear temperature dependence of resistivity are obtained. The thermal conductivity is large and has mainly phonon origin. Appreciable anomalies of transport characteristics near the antiferromagnetic transition point are found. Possible influence of pseudo-Kondo scattering is discussed.
