The geochemical and metallogenic specialization and zoning of structural-material complexes are analyzed. In the general systematic operational circuit of metallogenic forecasting and geological prospecting, processing the data on the geochemical specialization of geological formations and their constituents make it possible to perform a formational interpretation of anomalous geochemical fields revealed in the course of multipurpose geological and geochemical mapping; to subdivide the explored areas by the types of geological formations differing by their ore-bearing potential, with allocation of the most productive subformations, phases, and facies; and to provide quantitative estimates of the forecasted resources. Geochemical criteria of the ore-bearing potential of geological formations consist, first of all, in stable correlations between petrochemical features of ore-bearing rocks and their corresponding fluctuations of the ore composition (for example, the correlation of the potassium content of ore-hosting silicic volcanic rocks of the ore-bearing volcanogenic geological formations with the Cu/Pb ratio in ores of various types of deposits of the VMSD formational family). These criteria are to be taken into account in regional and local assessments of the perspective ore-bearing potential of geological formations.

In Sanfu, Qaidam basin, China, traditional geophysical methods have failed to find subtle hydrocarbon reservoirs. In an attempt to predict and delineate gas reservoirs, we used a type of magnetotelluric (MT) profiling called 3D continuous electromagnetic profiling (CEMP). Electric logs indicate that gas-bearing formations have high resistivity relative to nongas-bearing formations. Obvious resistivity anomalies derived from MT sounding curves are interpreted to come from gas-bearing formations; we observed no such anomalous resistivity away from gas-bearing reservoirs. For CEMP, five electric components were recorded at each station; the inline electric components of all stations were measured using dipoles placed end to end. Becausethe survey area was quite wide, we divided it into three rectangular blocks for data processing and inversion. After noise removal and static corrections, the data from each block were inverted with a 3D nonlinear conjugate-gradient inversion method to obtain the spatial distribution of resistivity. Using this resistivity, we created a 2D model, which we inverted to determine the induced polarization (IP) parameters. We found that a high-resistivity anomaly and high IP anomaly are two key indicators when predicting and delineating the location of gas-bearing reservoirs. In our case study, a known gas-bearing formation had a high-resistivity anomaly and a high IP anomaly. We identified two similar anomalous regions outside the known gas-bearing formations. As a result, two new prospects were determined as targets worth drilling.

Petroleum sediments in Azerbaijan have been researched and described by now in the form of complexes. Not only oil and gas deposits, but also the fields and accumulations of bitumen, bituminized rocks and oil shales are associated with these sediments. Furthermore, there are iodine, brom, the components of natural soda and so on in the oil, oil products and sediments as well. Alongside with it, a great amount of valuable metals present in the content of oil, produced water, bitumen and oil shales as an addition. This circumstance dictates the necessity of formation division of oil sediments. There are ten oil formations: Upper Pliocene-Lower Pleistocene, oil bearing-terrigenic; Middle Pliocene, oil-gas-bituminous-terrigenic; diatom-oil bearing-sand-clay; Miocene, oil-bituminous-sand-aleurite; Upper Oligocene-Miocene, oil bearing-terrigenic-carbonate; Eocene, oil bearing-clay-sand-marly; Upper Cretaceous, oil bearing-carbonate; Lower Cretaceous, oil bearing-terrigenic-carbonate; Upper Jurassic, oil bearing-sand-aleurite.

Abstract This paper presents a case study on the prediction of hydrocarbon reservoirs within coal-bearing formations of the Upper Palaeozoic. The target reservoirs are low-permeability low-pressure tight-sandstone reservoirs in the Daniudi Gas Field, Ordos Basin, China. The prime difficulty in reservoir prediction is caused by the interbedding coal seams within the formations, which generate low-frequency strong-amplitude reflections in seismic profiles. To tackle this difficulty, first, we undertook a careful analysis regarding the stratigraphy and lithology of these coal-bearing formations within the study area. Then, we conducted a geostatistical inversion using 3D seismic data and obtained reservoir parameters including seismic impedance, gamma ray, porosity and density. Finally, we carried out a reservoir prediction in the coal-bearing formations, based on the reservoir parameters obtained from geostatistical inversion and combined with petrophysical analysis results. The prediction result is accurately matched with the actual gas-test data for the targeted four segments of the coal-bearing formations.

In Western Romania diatomite occurs only in the Lower Sarmatian (Middle Miocene) formations, as a consequence of intense volcanism developed in Apuseni Mountains and evolution of peculiar sedimentary basins connected to the Pannonian realm. The main basins with diatomite successions are Zar and and VadBorod. The diatomite preserves besides diatoms (centric and pennate) and other microfossils (dinoflagellates, ebriidinas, silicoflagellates, phytolites) assemblages a lot of macrofossils as plants (mainly foliar imprints), fish, reptiles and mammals. Several taxa are indicative for environment reconstruction. The Lower Sarmatian climate is estimate as wet warm temperate to subtropical. A tentative of both aquatic and land environments reconstruction is done.
Erskine, Julian. "Dynamic Control and Singularities of Rigid Bearing-Based Formations of Quadrotors." Thesis, Ecole centrale de Nantes, 2021. http://www.theses.fr/2021ECDN0044.
Le contrôle des formations basées sur les bearings (direction relative à l’observateur) permettent aux flottes de quadrirotors de se déplacer vers une géométrie désirée, en utilisant des mesures extraites de caméras embarquées. Des travaux antérieurs ont traité les quadrirotors comme des intégrateurs, et donc la formation doit ralentir de manière à compenser les non-linéarités non modélisées. Cette thèse a pour objectif d’atteindre des formations rapides en tenant compte des dynamiques non-linéaires du quadrirotor et des mesures visuelles. Deux contrôleurs sont développés, à savoir un contrôleur basé sur un asservissement visuel dynamique et une commande prédictive, montrant des performances améliorées avec des contraintes réelles. Toutes les formations basées sur des bearings dépendent d’un degré suffisant de rigidité. Bien que celui-ci puisse être évalué numériquement, la rigidité est une fonction de la position de tous les robots dans la flotte. Ceci étant, les travaux précédents ne pouvaient pas garantir la rigidité pour des formations plus larges que quelques robots. La deuxième contribution de cette thèse est l’évaluation des géométries singulières où une certaine formation rigide devient flexible. Ceci mène à un système de classification basé sur des contractions d’ensembles de contraintes, qui permet d’identifier les géométries singulières pour des grandes formations afin de garantir la rigidité Bearing formation control allows groups of quadrotors to manoeuver in a desired geometry, using only visual measurements extractable from embedded monocular cameras. Prior works have treated quadrotors as single or double integrators, and as a result must operate slowly to compensate for unmodelled non-linearities. This thesis allows for faster bearing formations by developping higher-order controllers, considering the non-linear quadrotor and visual feature dynamics. A dynamic feedback controller based on second-order visual servoing and a model predictive controller are developped and tested in simulation and experiments, showing improved dynamic manoeuvering performance. The later is augmented with constraints such as field of view limitations and obstacle avoidance. All bearing formation algorithms depend on a sufficient degree of bearing rigidity to guarantee performance. This may be evaluated numerically, but as the rigidity is a function of the formation embedding, previous work could not guarantee rigidity in formations larger than a few robots. The second main contribution of this thesis is the evaluation of bearing rigidity singularities (i.e. embeddings where an otherwise rigid formation becomes flexible) by applying existing geometric analysis methods on an kinematic mechanism which is analoguous to the kinematic constraints imposed by the formation controller and robot models. This is extended to a novel classification system based on a contraction of constraint sets that can determine singular geometries for large formations, allowing for a formulation of a set of guaranteed rigid configurations without an ad-hoc kinematic analysis of individual formations

Tato disertační práce se zaměřuje na studium závislosti mezi reakčním momentem ložiska mazaného plastickým mazivem s lithným mýdlem a vlastnostmi maziva, jako například tloušťka vytvářeného mazacího filmu, jeho reologie, struktura zpevňovadla, trakční vlastnosti či vliv topografie povrchu. Typ maziva poskytujícího nižší odpor závisí na podmínkách provozu ložiska, zejména rychlosti. Chování mazacího filmu za nízkých rychlostí má vliv na reakční moment ložiska v nízkých rychlostech. Mez toku a trakční chování koreluje s momentem ložiska za vysokých rychlostí. Schopnost zpevňovadla vstupovat do kontaktu má vliv na tloušťku filmu, vzhled kavitační oblasti na výstupu kontaktu a chování hladovění. Důvod vstupu zpevňovadla do kontaktu je jeho chemická struktura. Vysoká polárnost hydroxylových sloučenin zpevňovadla podporuje jeho vtažení kontaktními povrchy. Mazivo s nejvyšší polaritou prokázalo na površích obsahujících denty nejčastější vstup do prostoru dentů. Na základě předchozích pozorování je navržen popis principu mechanismu mazání.

Khan, Fareed Ashraf. "Some aspects of convection as well as graphite and carbide formations during casting." Licentiate thesis, KTH, Metallernas gjutning, 2018. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-228388.
It is an established fact that segregation during casting affects the physical properties of carbon-based ferro alloys; this motivates the study of the segregation behaviour of carbon and carbide-forming solute elements. In this context, this thesis investigates two different situations: the effects of cooling rate and turbulence on the precipitation behaviour of the graphite nodules in nodular cast iron; the nature of carbide precipitation in a bearing steel grade and the effects of subsequent soaking on these carbides. The structures of boiling water reactor inserts cast by the uphill and downhill casting of nodular cast iron were examined. The samples were taken from representative locations in the top, middle and bottom cross sections of the castings. It was observed that in uphill-cast inserts the nodules were larger but fewer in number the bottom section, whereas in downhill-cast inserts the nodules in the bottom section were smaller, but greater in number. Variation in volume fraction of the graphite nodules across the inserts was also observed. The probable cause of this variation was the difference in cooling rate in different sections of the insert. Between the steel tubes located at the central part of the casting, the fraction of graphite was lower, which could be the result of carburization of the steel tubes. To study the effects of melt stirring during the solidification of nodular cast iron, several experiments were conducted at variable cooling rates and for different stirring times. Examination of the microstructure was conducted using Light Optical Microscope (LOM) and Scanning Electron Microscope (SEM). It was observed that during stirring the melt oxidized and oxide nuclei were formed. The number of nucleation sites for the precipitation of graphite nodules increased, which raised the nodule count and the fraction of the graphite precipitated. The matrix transformed from pearlite to ferrite, which could be due to the fact that more carbon had diffused out of the matrix. The segregation behaviour in hypereutectoid bearing steel produced by ingot casting was also studied. The effects of soaking on micro and macro segregation was investigated in samples taken from as cast and soaked ingots; emphasis was laid on the bulk matrix and A-segregation channels. Samples were also taken from ingots which were soaked and then hot worked. The micro and macro examination of the microstructure was conducted using LOM and SEM. Quantitative and qualitative composition analysis was performed using Energy-dispersive X-ray spectroscopy (EDX) and an electron micro probe analyzer (EMPA). It was observed that M3C, M2C and M6C had precipitated. The carbide morphology in the bulk matrix was different to that in the A-segregation channels. All the primary carbides in the bulk matrix were found to have dissolved after 4 hours of soaking at 1200oC. Det är ett faktum att segringar som uppstår under gjutning påverkar materialegenskaperna hos kolbaserade järnlegeringar; detta utgör motivationen till studien av segringsuppträdandet hos kol och karbidbildande ämnen. Denna avhandling behandlar två olika aspekter inom ramen för detta ämne: påverkan av kylningshastighet och turbulens på kärnbildningen av grafitnoduler i nodulärt gjutjärn samt karbidbildning i kullagerstål och dess påverkan på den efterföljande värmebehandlingen av dessa karbider. Strukturen hos rör till vattenkokare som tillverkats av nodulärt gjutjärn som gjutits med fyllning från botten eller från toppen undersöktes. Prover togs från representativa tvärsnittspositioner från toppen, mitten och botten av de gjutna ämnena. Resultaten visade att användandet av bottenfyllda kokiller gav upphov till större men färre karbider i nedre delen av ämnet, medans användandet av toppfyllda kokiller gav upphov till mindre men fler karbider i nedre delen av ämnet. Variationer av volymfraktionen av grafitnoduler längs tvärsnitten observerades också. Den mest sannolika orsaken till denna variation var skillnaden i kylhastighet i de olika områdena av tvärsnitten. Hos rör tillverkade av det centrala delen av ämnet så var fraktionen grafit lägre, vilket kan bero på en uppkolning av rören. Ett flertal experiment utfördes med varierande kylningshastigheter och olika omrörningstider för att studera inverkan av omrörning av smältan på stelningen av nodulärt gjutjärn. Studier av mikrostrukturen genomfördes med ljusoptisk mikroskopi och svepelektronmikroskopi. Resultaten visade att smältan oxiderades under omrörningen, vilket resulterade i bildandet av oxider. Detta ledde till en ökning av kärnbildningsområden för grafitnoduler, vilket ledde till en ökning av antalet noduler samt fraktionen av grafit som fälldes ut. Strukturen omvandlades från perlit till ferrit, vilket troligen orsakades av att kol hade diffunderat ut från strukturen. Segringsbeteendet hos hypereutektoida kullagerstål tillverkade genom götgjutning undersöktes också. Effekten av värmebehandling på mikro- och makrosegringar undersöktes i prover tagna från gjutna och värmebehandlade ämnen. Fokus var på att studera strukturen i ämnena samt A-segringar. Dessutom togs prover från ämnen som först värmebehandlats och därefter varmbearbetats. Både mikro- och makroundersökningar av mikrostrukturen utfördes med ljusoptisk mikroskopi och svepelektronmikroskopi. Dessutom så genomfördes kvantitativa sammansättningsbestämningar med energidispersiv röntgenspektroskopi och elektronmikroprobsanalys. Resultaten visade att M3C, M2C och M6C karbider hade fällts ut. Karbidmorfologin i huvuddelen av strukturen skiljde sig från den som återfanns i A-segringar. Samtliga primära karbider i huvuddelen av strukturen hade lösts upp efter 4 timmars värmebehandling vid 1200oC.

The formation of iron-bearing intermetallics in the 413 type of aluminum alloys was investigated comprehensively. Both synthetic and commercial 413 alloys were studied with iron concentrations in the range of 0.4-1.2 wt. % and manganese up to 0.5 wt.%. The effects of cooling rate during solidification and of melt chemistry on the morphology of iron intermetallic phases were determined. Image analysis was used to quantify the intermetallic size, volume fraction, and number, as a function of both melt chemistry and cooling rate. The total volume fraction of intermetallic compounds in these alloys was related to cooling rate by an exponential equation. The kinetics of both dissolution of intermetallics on melting, and of re-formation on cooling of the liquid were investigated by means of quenching experiments. Quantitative evaluation of intermetallic size and number revealed that the change in volume fraction of intermetallics in the liquid state is controlled by nucleation. The effect of settling time and the rate of gravity segregation of intermetallic compounds in a stagnant liquid metal were investigated. It was found that, in the absence of convection, settling obeys Stokes' law with the terminal velocity reached at very short times and very close to the melt surface. Strontium was used to modify or eliminate the iron-intermetallics. (Abstract shortened by UMI.)

It is believed that home ownership has a positive connection with family formation and child bearing as there is a speed up process of attaining home-ownership when the couples are in anticipation of starting family and having children. However, home ownership in relation with family formation and child bearing are not always in positive connection as other factors are necessary to be taken into consideration when associating relationship between them, such as (i) postponement of marriage and child bearing, (ii) family background, (iii) housing markets and financial systems, and (iv) government policies which will be investigated internationally in this research and tested the hypothesis in Hong Kong.
With the family budget constraints, cost competition between housing and marriage or child bearing is one of the significant factors affecting the couples’ decision in home purchasing. Our empirical results from the questionnaire survey demonstrated that home ownership is perceived as a precondition to marriage and child bearing and indicated that the cost competition between becoming home owners and becoming parents was strong. Postponement of marriage and child bearing are found over the past decade and decrease in number of children that the respondents wanted to have are the current trend. Our empirical results also show that family background is an important factor affects decision of the couples in home purchasing when getting married and in anticipation of having children. Facing a budget constraint, most of the young couples depend on their parents who are in owner-occupied housing tenure for financial assistance to succeed their home purchasing dreams.
Nowadays, Hong Kong residential property value has also increased sharply in recent years and costs of housing with increasing mortgage rate would affect decision of the young couples in home purchase, a series of measures are therefore launched by the government to solve the problems of housing since its inauguration aiming at increasing private and subsidized housing flats as well as land for affordable housing development to cool down the overheating property market. People’s home purchase is greatly affected by the prevailing housing policy found in the survey and their recommendations to the government are to provide more HOS flats, stabilize the house price, increase in amenities and facilities provision in the suburb housing developments and resume Home Assistance Loan Scheme in order to satisfy their housing needs in forming families and planning to child bearing. published_or_final_version Housing Management Master Master of Housing Management

Abstract Designing an onshore pilot well to be drilled and functioning as water disposal well targeting one of three potential formations to test and evaluate their injectivity. Based on evaluation results, an alternative new and deeper formation will be selected to dispose the unwanted associated produced water, instead of the current shallow formation that is considered as a natural aquifer by authorities. The well is designed to reach the first target in a deviated angle after which evaluation of the barefoot injectivity testing will begin. The decision whether to continue drilling to a secondary target or complete the well depends heavily on the injectivity testing results. The deviated angle of drilling will be dropped to reach a vertical position for the secondary target upon which the last liner will be run and perforated, then the formation testing will be conducted. In case of encounterg failure in the second injectivity testing, drilling to the deepest target will continue and final barefoot testing will be performed. A final optimal design for the pilot disposal well is intended to meet the reservoir and geological team with minimal drilling risks. The distance between this well and the other deep offset wells was the main challenge where the planned total depth was never reached in the disposal location. Also, the design was tailored to accommodate the drilling sections with the separation and long intervals between the targets. Furthermore, the uncertainty of the deepest formation fluid in addition to the uncertainties of formations pressure and formations fracture pressure were a big dispute while preparing the drilling fluids programs particularly across the target in which a water based mud was used as drilling fluid not to damage the formations nor to jeopardize the results of the injectivity tests. The pilot disposal well is drilled successfully penetrating two targets without the need to drill to the third formation. Hence, the new formation that will be used to dispose of the produced but unwanted water is defined after the reservoir team have evaluated the two injectivity tests. The results of the injectivity evaluation also provided the required number of wells that can handle all the expected produced water, and provided the required upgrade for the surface facilities to accommodate the injection pressure. This unique challenging well design, combining slanted and vertical trajectories, can be utilized whenever the budget is limited to one well, while you have multiple different targets to explore. Moreover, a specialized environmental impact study, conducted by independent contractor, confirms that there was no harm from the injected water to the groundwater.
