Abstract:
An active electromagnetic stabilization of the Leipholz column We study the application of electromagnetic actuators for the active stabilization of the Leipholz column. The cases of the compressive and tensional load of the column placed in air and in water are considered. The partial differential equation of the column is discretized by Galerkin's procedure, and the stability of the obtained control system is evaluated by the eigenvalues of its linearization. Four different methods of active stabilization are investigated. They incorporate control systems based on feedback proportional to the transverse displacement of the column, its velocity and the current in the electromagnets. Conditions in which these strategies are effective in securing safe operation of the column are discussed in detail.

According to the results of the study, we found that increasing the pressure in a stabilization column improves the sharpness of separation of butanes from pentanes. As a result, the product quality is getting better. The pilot-industrial runs confirm the possibility of improving the effectiveness of the stabilization columns in various processes by increasing the pressure within the permissible limits.

Abstract:
Deep lime stabilization such as lime column, can effectively improve the problematic soft clay through stabilization, settlement reduction and embankment stabilization. Nevertheless, the reduction of lime column load capacity was often encountered due to the column lateral displacement which was induced by high lateral earth pressure in embankments and deep excavation. In order to protect and enhance the mobilization of lime column strength, geotextile encapsulation was proposed for lime column. In this study, large shear box tests were conducted on lime column and geotextile encapsulated lime column (GELC) stabilized Pontian marine clay samples with different column sizes and curing ages, in order to investigate the performance of geotextile encapsulation on lime column in Pontian marine clay under shear loading. It was found that geotextile encapsulation effectively increased the horizontal shear resistance of lime column and protected the column from defect due to lateral displacement, especially at early age when modification was still in process. Geotextile encapsulation also successfully protected lime column from shear and bending failure under lateral load.

Abstract:
Suite à la mise en place de politiques publiques favorisant les énergies renouvelables, la construction de fermes éoliennes offshore est en plein essor aux quatre coins du monde. Or, la technique de l'éolienne offshore posée, la seule utilisée actuellement, n'est pas viable économiquement dans des eaux trop profondes. Ceci représente un sérieux frein au développement de l'énergie éolienne. Pour cette raison, la communauté scientifique s'intéresse depuis plusieurs années aux éoliennes sur plates-formes flottantes. En eau profonde, cette technologie est intéressante. Mais le fait que l'éolienne ne soit pas encastrée au fond de la mer augmente très significativement les sollicitations mécaniques induites par les vagues.Pour réduire ces sollicitations qui ont de nombreux effets néfastes, différentes approches sont possibles. Essayer de compenser les oscillations « avant-arrière » du mât de l'éolienne en pilotant la force de poussée exercée au niveau du rotor a déjà été écarté dans la littérature. Nous nous sommes concentrés sur l'ajout d'un dispositif de stabilisation interne à la plate-forme, de type Tuned Liquid Column Damper (un tube en U contenant un liquide, TLCD, encore appelé tube anti-roulis), utilisé dans d'autres contextes. Le dispositif que nous proposons est un dispositif actif où les paramètres du TLCD sont ajustés en temps réel, au cours du mouvement induit par les vagues. La mise à jour des paramètres suit une stratégie reposant sur une analyse des interactions entre le TLCD et la plate-forme (appelée ici barge) sur laquelle est installée l'éolienne. Nous avons modélisé le mouvement de la barge seul et son couplage avec le TLCD dans le plan grâce à une approche Lagrangienne. Nous avons étudié les effets des interactions du TLCD avec la barge dans le cas où le coefficient de perte de charge dans le tube était constant. Les limites de cette approche ont été détaillées grâce aux résultats classiques de la littérature sur les oscillateurs mécaniques couplés. Nous nous sommes ensuite concentrés sur une approche active consistant à modifier les caractéristiques du système en temps réel. Nous avons proposé des stratégies de type Linear Quadratic Regulator et de type Model Predictive Control agissant sur le coefficient de perte de charge. Dans un deuxième temps, les simulations nous ont ensuite permis d'écarter la commande MPC dont le rapport performance / complexité n'est pas favorable par rapport à la commande LQR dans ce cas précis.Une étude plus générale du système, en trois dimensions, nous a permis de vérifier que le TLCD classique dans sa version passive ou dans la version active que nous proposions n'est pas du tout robuste à l'incidence de la houle. Nous avons donc imaginé et modélisé des dispositifs inspirés du TLCD mais permettant d'amortir les oscillations de la houle de manière efficace, indépendamment de l'incidence de la houle. Nous avons nommé ces dispositifs TLMCD, pour Tuned Liquid Multiple Columns Damper.Les dispositif que nous proposons sont des systèmes TLMCD actifs. Ils sont conçus d'après les modélisations 3D que nous avons développées et une étude des coûts. Pour ces dispositifs, nous avons aussi détaillé les spécificités de la synthèse des stratégies LQR pour amortir les oscillations de la barge indépendamment de l'incidence de la houle.La performance de ces solutions d'amortissement a finalement été évaluée par simulation pour un large éventail de conditions de houle, couvrant les spécifications d'un “ cahier des charges ” que nous présentons. On observe une réduction des oscillations en roulis de la barge qui peut atteindre un facteur 4 par rapport à l'éolienne flottante sans TLCD. Ces résultats nous montrent que le dispositif TLMCD que nous proposons est un dispositif intéressant pour amortir de manière significative, robuste et économiquement abordable notre système
Thanks to the recent policies of subsidizing renewables energies, constructions of offshore wind farms are booming all over the world. Yet, fixed-bottom wind turbine technology, the only one currently deployed, are too costly for deep waters. This hinders the development of wind power. This is why the scientific community has an interest in floating wind turbines (FWT). The cost of these wind turbines does not depend much on water depth. But since the wind turbine is not fixed into the seabed, the mechanical stress caused by the waves significatively raises.To reduce these detrimental loads, different approaches can be used. The litterature already discarded the control of the wind thrust applied on the rotor to compensate the "fore-aft" oscillations of the tower. We focused on stabilizing floating wind turbine by means of an attached damping system placed inside the float, it is a Tuned Liquid Column Damper (a U-tube containing a liquid, TLCD, also known as anti-roll tank), used in other areas. The damper we propose is an active system where TLCD parameters are continuously modified. Parameters are updated according to a strategy defined thanks to an analysis of the interactions between TLCD and the float (referred to as barge) supporting the wind turbine. We modelled the coupled dynamics of the barge and the TLCD in the vertical plan using a Lagrangian approach. We studied the motions of the damped system for a constant head-loss coefficient in the TLCD. The limits of this approach were detailed thanks to the classic results in double oscillators literature. Then, we focused on an active approach involving a time varying of the head-loss coefficient. We proposed Linear Quadratic Regulator and Model Predictive Control strategies to determine the head-loss coefficient. At a later stage, simulations enabled us to discard the MPC strategy as its complexity/performance ratio is rather bad compared to the LQR strategy in this particular case.A more general study of the system, in three dimensions, showed us that the TLCD is not robust against wave incidence. Therefore, we imagined and modeled new dampers inspired by the TLCD, which can damp the float effectively, regardless of the wave incidence. We named those dampers Tuned Liquid Multiple Column Damper (TLMCD).The dampers we propose are active TLMCD. Their designs are based on their dynamic properties and a cost study. We also detailed the specificities of LQR design to ensure the best possible robustness against wave incidence.The performance of the proposed TLMCD dampers was assessed through numerical simulations for a wide range of sea conditions. We observe that barge roll can be reduced by a factor of four compared to the undamped FWT. These results show us that the TLMCD we propose is interesting to damp significantly, robustly and economically our FWT

Abstract:

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility. An additional study to examine this risk has therefore also been performed.

The project started with a pilot study in order to identify the material fraction that was suitable for the experiment. When suitable material had been chosen, a column test was carried out for the purpose of studying the slurry’s influence on the mobility of metals along with the production of acidity. To clarify the organic material’s potential for complexation a pH-stat batch test was used. Drainage water samples, from the columns, were regularly taken during the experiment. These samples were analysed for pH, electrical conductivity, alkalinity, redox potential, dissolved organic carbon (DOC), sulphate and leaching metals. The effluent from the pH-stat-test were only analysed on a few occasions and only for metal content and change in DOC concentration.

The results from the laboratory experiments showed that the waste rock from Ljusnarsberg easily leached large amounts of metals. The stabilization of the waste rock succeeded in maintaining a near neutral pH in the rock waste leachate, compared to a pH 3 leachate from untreated rock waste The average concentration of copper and zinc in the leachate from untreated waste rock exceeded 100 and 1000 mg/l respectively, while these metals were detected at concentrations around 0.1 and 1 mg/l, respectively, in the leachate from the treated wastes. Examined metals had concentrations between 40 to 4000 times lower in the leachate from treated waste rock, which implies that the stabilisation with reactive amendments succeeded. The long term effects are, however, not determined. The added sludge contributed to immobilise metals at neutral pH despite a small increase in DOC concentration. The problem with adding sludge is that if pH decreases with time there is a risk of increased metal leaching.


Gruvavfallet från Ljusnarsbergsfältet i Kopparberg anses utgöra en stor risk för människors hälsa och den omgivande miljön. En del av varpmaterialet, ofyndigt berg som blir över vid malmbrytning, utgörs av sulfidhaltigt mineral. Då varpen exponeras för luft och nederbörd sker en oxidation av sulfiderna, vilket kan ge upphov till surt lakvatten och läckage av tungmetaller. Syftet med arbetet har varit att karaktärisera varpen och försöka stabilisera den med en blandning bestående av mesakalk och avloppsslam, samt att undersöka risken med det lösta organiska materialets förmåga att komplexbinda metaller och på så vis öka deras rörlighet.

Efter insamling av varpmaterial utfördes först en förstudie för att avgöra vilken fraktion av varpen som var lämplig för försöket. När lämpligt material valts ut utfördes kolonntest för att studera slam/kalk-blandningens inverkan på lakning av metaller, samt pH-statiskt skaktest för att bedöma komplexbildningspotentialen hos det organiska materialet vid olika pH värden. Från kolonnerna togs lakvattenprover kontinuerligt ut under försökets gång för analys med avseende på pH, konduktivitet, alkalinitet, redoxpotential, löst organiskt kol (DOC), sulfat och utlakade metaller. Lakvattnet från pH-stat-testet provtogs vid ett fåtal tillfällen och analyserades endast med avseende på metallhalter och förändring i DOC-halt.

Resultatet från den laborativa studien visade att varpmaterialet från Ljusnarsberg lätt lakades på stora mängder metaller. Den reaktiva tillsatsen lyckades uppbringa ett neutralt pH i lakvattnet från avfallet, vilket kan jämföras med lakvattnet från den obehandlade kolonnen som låg på ett pH kring 3. Medelhalten av koppar och zink översteg under försöksperioden 100 respektive 1000 mg/l i lakvattnet från det obehandlade avfallet, medan halterna i det behandlade materialets lakvatten låg kring 0,1 respektive 1 mg/l. Av de studerade metallerna låg halterna 40-4000 gånger lägre i lakvattnet från den behandlade kolonnen, vilket innebär att slam/kalk-blandningen har haft verkan. Stabiliseringens långtidseffekt är dock okänd. Det tillsatta slammet resulterade inte i någon större ökning av DOC-halten i det pH-intervall som åstadkoms med mesakalken. Utifrån pH-stat-försöket kunde det konstateras att det tillsatta slammet bidrog till metallernas immobilisering vid neutralt pH, trots en liten ökning av DOC-halten. Om en sänkning av pH skulle ske med tidens gång föreligger dock risk för ökat metalläckage.

Abstract:
O problema de corte de estoque consiste em cortar objetos maiores, disponíveis em estoque, para produzir uma quantidade especificada de peças menores, de modo que uma certa função objetivo seja otimizada. Um modelo de otimização linear tem sido amplamente utilizado na solução deste problema desde os anos 60, que incorpora parte da estrutura combinatória inerente ao problema na construção das colunas da matriz de restrições. As colunas são construídas a cada iteração do Método Simplex, chamando-se geração de colunas. Apesar do método Simplex ser largamente utilizado para este tipo de problema, apresenta baixa convergência quando próximo da otimalidade, pouco melhorando a função objetivo. Assim, estratégias para aceleração do Método Simplex faz-se necessário, uma maneira consiste na redução do espaço dual, com a introdução de restrições (colunas no primal) que evite grandes variações nas variáveis duais, chamadas cortes duais. Neste trabalho, generalizamos duas famílias de cortes duais recentemente publicadas e analisamos o impacto computacional desses cortes duais sobre a convergência do Método Simplex
The cutting stock problem consists of cutting large available objects in stock to produce a quantity of ordered smaller itens, in such a way as to optimize a given objective function. A linear optmizatim model has been widely used to solve this problem since the 60s, in which part of a combinatorial structure of the problem is embedded. The columns of the constraint matrix are generated in each iteration of the Simplex Method, called the column generation technique. Although, the Simplex Method is widely used, it has a low convergence near to optimality. In this way, strategies to accelerate the Simplex Method are welcome which can be obtained by adding dual cuts (primal columns). The goal of this work is to study published dual cuts and to proposed others. In this book us extend two families of dual cuts, which were recently published, and analyse the computational impact of these dual cuts on the converge of the Simplex Method

Abstract:
Rockfill columns have been used to stabilize the clay riverbanks in the Winnipeg area for over two decades. The construction methods used in Manitoba are uniquely adapted to the local soil conditions. The performance of rockfill columns in Manitoba has generally been satisfactory, except that in some cases significant deformations have occurred during and after construction (Yarechewski and Tallin 2003). This thesis will discuss the full-scale test loading of a riverbank that was stabilized with rockfill columns. The purpose of the test was to measure the load-deformation characteristics of a reinforced slope in order to further the understanding of rockfill column behaviour. Rockfill column technology has evolved from granular shear key methods for stabilizing slopes. The relatively weak and soft lacustrine clay is reinforced with compacted columns of stronger and stiffer limestone rockfill. The research test site is located along the natural banks of the Red River in The City of Winnipeg. The project involved an extensive site investigation, and soils characterization program in preparation for the field test. Eleven columns, 2.1 m in diameter were tested by surcharging the slope with 1920 tonnes of fill. The deformations were measured with standard and in-place inclinometers while the porewater pressure response of the in-situ soils was continuously monitored with vibrating wire piezometers. The research further investigated the mobilization of resistance along the length of the rockfill columns with finite element models. The analysis of the model results illustrated the mobilization of shear resistance within the rockfill and the development of stresses across the column cross section. The important engineering characteristics of rockfill are discussed in the context of rockfill column design and the importance of effective compaction is highlighted. The results of this research are used to develop recommendations for rockfill column design, analysis and construction.

Abstract:
Abstract The human thoracolumbar spinal column sustains axial loading under physiological and traumatic loading situations. Clinical studies have focused on the former scenario, and the investigation of low back pain issues and spinal stabilization using artificial devices such as arthroplasty are examples. Investigative studies have largely used quasi-static and vibration loading on the spine segment(s) and spinal columns. The traumatic loading scenario is relatively less researched, and it is a dynamic event. Injuries under this scenario occur in sports, automotive, and combat environments. Impact vectors include flexion-extension modes in automotive crash events. Vertical or caudal to cephalad oriented impacts have been identified in both automotive and military scenarios. Frontal impacts to restrained occupants in the automotive and underbody blast impacts from improvised explosive device in combat situations are examples of the vertical loading vector. Although some studies have been conducted using whole body human cadavers and isolated spinal columns, determinations have not been made of the injury risks and stress and strain responses for a variety of accelerative pulses. The aims of the present investigation were to delineate the internal biomechanics of the spinal column under this impact vector and assess the probability of injury. Male and female whole-body human finite element models were used in the study. The occupants were restrained and positioned on the seat, and caudo-cephalad impacts were applied to the base. Different acceleration-time profiles (pulse durations ranging from 50 to 200 ms and peak accelerations varying from 11 g to 46 g) were used as inputs in both male and female models. The resulting stress-strain profiles in the cortical and cancellous bones were evaluated at different vertebral levels. Using the peak transmitted forces at the thoracolumbar disc level as the response variable, the probability of injury for the male spine was obtained from experimental risk curves for the various accelerative pulses. Results showed that the shorter pulse durations and rise times impart greater loading on the thoracolumbar spine. The analysis of von Mises stress and strain distributions showed that the compression-related fractures of vertebrae are multifaceted with contributions from both the cortical and cancellous bony components of the body. Profiles are provided in the body of the paper for different spinal levels. The intervertebral disc may be involved in the fracture mechanism, because it acts as a medium of load transfer between adjacent vertebrae. Injury risks for the shortest pulse was sixty-three percent, and for the widest pulse it was close to zero, and injury probabilities for other pulses are given. The present computational modeling study provides insights into the mechanisms of the internal load transfer and describe the injury risk levels from caudal to cephalad impacts.

Abstract:
A numerical finite-difference model, derived using a control-volume approach, was used to compute the flow and heat transfer characteristics in a two-dimensional confined laminar air jet impinging on an isothermal surface. Several cases were considered with Re=650, 750, and nozzle to plate spacing, H/W=5. The behavior of the jet and the attendant heat transfer from the target wall were investigated when the jet was forced by fluidic excitation at the nozzle exit. At Re between 585 and 610, the unforced jet exhibits a transition to an unsteady regime leading to asymmetric vortex shedding and jet flapping [1, 2]. Investigation of the velocity spectra indicate three distinct dominant modes; the lowest frequency is associated with the jet flapping while the highest frequency is associated with the asymmetric vortex formation which causes buckling of the jet column. As a result of the two combined modes, the peak heat transfer is enhanced and the lateral cooling extent is broadened. The jet was subjected to forcing by introduction of numerical excitation at each side of the jet that modeled fluidic excitation. The jet was forced on both opposing sides at its exit, both with in-phase and out-of-phase modes. Under some conditions, out of phase forcing at Re=650 at the highest frequency leads to stabilization of the normally separated flow on one side only. This unusual asymmetric flow field is unsteady but repeatable, and results in an enhancement of the heat transfer. At Reynolds number of 750, forcing with an out of phase mode at the highest frequency leads to a complete stabilization of the jet. The forcing suppresses the high-amplitude low frequency flapping mode leaving only a high frequency vortex formation mode. The suppression of the jet flapping leads to a decrease in the peak heat transfer, but because separation is suppressed, the average wall heat transfer is enhanced.

Abstract:
Abstract Discrete models of two drilling stabilizer designs are subject to analytical mechanics treatments to examine dynamic behavior and amplify insights into contribution to bottom-hole drilling assembly (BHA) dynamics stability. The spiral blade and straight blade design stabilizers are essential components of oil and gas BHA included to functionally provide stabilization during rotation of the BHA and stand-off from the walls of the oil and gas wellbore. Attempts are made from the onset to simplify model complexity and as a consequence ease of computational simulation. The answer to the seemingly intuitive question of the mechanical advantage offered by a spiral blade compared to a straight blade stabilizer design in a constrained dynamics representation is revealed by computing forces generated at the interface between the functional elements of the devices and the inelastic boundary (wellbore) to keep the constraint satisfied. Analytical mechanics approaches have been used to carry out 3-D dynamics analysis of bottom hole drilling assemblies using 3-D Euler-Bernoulli or Timoshenko beam-column finite-element representations and lumped-parameter model approximations of rigid body dynamics behavior. In this work, phase portraits of angular velocity versus displacement — parsed for torque generated — from numerical simulations for torque-free and applied external load states, and discussion, offer illuminating insights into downhole operating dynamics of these ubiquitous components of oil and gas well bottom hole assembly (BHA) drilling devices.

Abstract:
In this paper, the flow-thermal calculation of reboiler E10 in the process of desorption of light hydrocarbons, which is located in the bottom of the column for stabilization (desorption) of rich absorption oil in the plant "Refinery TNG", Elemir. In reboiler E10, heat is exchanged between warm oil (warmer fluid) and rich absorption oil (colder fluid). The observed reboiler E10 represents a heat exchanger with the so-called two passages. Warmer fluid flows inside the exchanger tube, in two passes; while the absorption oil flows through the annular space in one pass. It is assumed that in the E 10 reboiler, based on the data from the technical-technological documentation, the calculation of the relevant current and thermal quantities required for the process of heating the rich absorption oil can be performed. The results of the control flow-thermal calculation confirmed that the assumed value of the pipe length (and the values that result from and are relevant for the calculation) coincides with the value of the pipe length calculated in the realized calculation for reboiler E10. In this way, the correctness of the used equations for the subject calculation was confirmed. A complete overview of flow and thermal quantities in practice completely describes the operation of the E10 reboiler for heating rich absorption oil.
