Der volle Inhalt der QuelleAn additional problem in the flotation column was bubble coalescence and collapse of the froth. This was caused by the fatty acids, enhanced by the high dispersant concentration.
A novel method of quantifying coalescence using the change in gas holdup in the column was developed. A stable froth could be made at high fatty acid emulsifier concentration, but his promoted unselective flotation. Only by working at high percent solids (10% vs 1%) could sufficient emulsifier be introduced into solution without exceeding the dosage (per unit mass of solids) above which flotation is unselective. For such high percent solids work must be conducted at plant site. Preliminary plant column work was encouraging.
Extensive testwork on very fine feeds (80% $-$20 $ mu$m) at Niobec, and at Mt Isa Mines (Australia) confirmed that column flotation is ideal for selective flotation of fines principally due to reduced gangue entrainment.

Der volle Inhalt der QuelleKumba Iron Ore’s Sishen mine is located in South Africa’s Northern Cape Province and produces about 40 million tons (Mt) of iron ore per annum. The ore body consists mainly of laminated and massive type hematite ore of which 30 Mt is being beneficiated by Dense Medium Separation (DMS), while the remaining 10 Mt is processed by the jig plant that was added as an expansion to the DMS processing route. The jigs at the jig plant are employed to treat coarse, medium and fine Run of Mine Ore (ROM). Due to the presence of finer particles on the screened ROM, hydrocyclones are employed on the secondary screen that feed the finer jig to produce fines on the overflow that is fed to the thickeners for dewatering by sedimentation, and the formation of clear liquid that can be recycled to the Jig plant. However, it was suspected that a substantial amount of the iron gets lost to the hydrocylone overflow with slimes. These slimes consist of very fine particles (about 90%-45μm) which make treatment with gravity concentration methods difficult. Sishen mine attempts to beneficiate the slimes using Pulsating High Gradient Magnetic Separators (PHGMS). However, PHGMS produce a concentrate consisting of 64.0% iron and 5.0% silica which render the slimes not suitable for pelletizing. Normally the slimes are considered as waste and are rejected to the slimes ponds. Rejecting slimes is not only a loss of resources, but it also poses severe long-term environmental problems. Recovery of iron minerals from the tailings produced in a large iron ore operation is of importance as it will result in environmental and economic benefits which indicate the importance of utilising those accumulated fines.

Der volle Inhalt der QuelleThe city of Randfontein, in the Witwatersrand, hosts several slimes and tailings storage facilities which pose potential threat to the environment in the form of acid mine drainage (AMD). The latter, readily scavenges toxic metals, contaminating surrounding soils and water resources, thereby potentially compromising the overall environmental- and public health of the area. To this end, three slimes sections (section T001, T002 and T003) from the Gold One Millsite Slimes Complex were investigated, with the aim of understanding metal release from the slimes dam into the Randfontein area. To achieve this, the mineralogical and geochemical factors controlling metal release were investigated using combined core log analysis, cluster and discriminant analysis, x-ray diffraction analysis, bulk geochemical analysis, acid base accounting methods and selective sequential extraction procedures.

Der volle Inhalt der QuelleДиссертационную работу посвящено выявлению закономерностей процессов разделения шламовых вод с полидисперсной твердой фазой в осадительных центрифугах. В работе всесторонне исследовано влияние концентрации и дисперсного состава на прочность флокул к механическим воздействиям. Установлено, что остаточная скорость осаждения флокул после механического воздействия при постоянном расходе флокулянта имеет наибольшее значение при концентрации твердой фазы в шламе в интервале 7–30 г/дм3. Наилучшие результаты во всех опытах получены при концентрации твердой фазы, равной 10 г/дм3. Выявлено, что при концентрации до 7 г/дм3и свыше 30 г/дм3 наблюдается образование флокул, обладающих наименьшей остаточной скоростью после механических воздействий. С ростом содержания доли твердой фазы крупностью 40–100 мкм свыше 15 % возрастает прочность флокул, которые сохраняют свою форму и достаточно высокую скорость осаждения даже после механических воздействий. Разработаны рекомендации по выбору технологических параметров обезвоживания шламовых вод различных производств в осадительных шнековых центрифугах с использованием химического усиления флокулянтами агрегатообразования полидисперсных шламов. Полученные данные позволяют рекомендовать корректировку состава шлама перед вводом флокулянта как по концентрации, близкой к оптимальной, так и по содержанию доли класса крупностью 40–100 мкм свыше 15 %. Показано, что с ростом концентрации твердой фазы в сгущенном шламе свыше 140–150 г/дм3 существенно уменьшается прочность агрегатов к механическим воздействиям. Это позволяет рекомендовать сгущать шлам до заданной величины. Предложены пути минимизации механических воздействий на сфлокулированный шлам в центрифуге. В частности, предложен способ модернизации конструкции центрифуги, заключающийся в том, что вдоль боковой поверхности трубы питания выполнены каналы, направленные тангенциально к боковой поверхности трубы питания таким образом, чтобы направление течения суспензии из каналов совпадало с направлением вращения ротора. В результате такой подачи только малая часть потока испытывает сдвиговые напряжения. Другим направлением, снижающим механические воздействия на флокулы является установка в барабане разгонной втулки с направляющими трубками, препятствующими разбрызгиванию суспензии. В результате этих рекомендаций разработана усовершенствованная конструкция осадительной центрифуги, обладающая при соблюдении оптимальных условий флокуляции высокой степенью удаления твердой фазы, возможностью получения осадка относительно низкой влажности, а также низким расходам энергии на процесс.
The thesis is concerned with conformities to the law of processes of division of slime waters with a polydispersed hard phase in decanting centrifuges. The influence of concentration and dispersible composition on durability of floccules to mechanical influences was investigated in detail. The effect of the concentration and disperse composition on the flocculation strength to mechanical influence is investigated. It is found that the residual rate of floccules sedimentation after the mechanical influence at a constant rate of flocculant has a maximum value at a concentration of solids in the slime in the range of 7–30 g/dm3. The best results are obtained in all the experiments at a solids concentration of 10 g/dm3. It is found that at a concentration up to 7 g/dm3 and more than 30 g/dm3, the floccules are formed. They have the lowest residual rate after mechanical influences. With increasing content of the solid fraction of 40 – 100 microns over 15%, the strength of floccules increases. They retain their shape and relatively high sedimentation rate even after mechanical influence. The obtained data allow recommending correction of the slime composition before flocculant injection both the concentration close to the optimum, and the content of size fraction of 40 – 100 microns more than 15%. It was offered that with an increase in the degree of thickening of more than 140–150 g/dm3 the resistance of aggregates to mechanical influence substantially decreases.

Der volle Inhalt der QuelleThe efficiency of desktop publishing is severely limited by the lack of sophisticated automatic document layout systems. State-of-the-art algorithms either require the input to be written in a description language such as HTML and LaTeX, or to be a manually designed layout template. However, description languages are ill-suited to express layout problems with weak semantics and layout templates shift the burden from the end user to the template designer. The first contribution of this thesis is an algorithm that solves a general class of layout problems by treating them as equitable resource allocation problems. The available document area is a resource that is distributed among inter-element gaps. The layout problem is transformed into a lexicographic min-ordering optimization problem that is solved using linear programming techniques in real-time. If the layout problem is over-constrained, the quality of the solution layout degrades gracefully. The layout algorithm finds the solution layout with the most equitable distribution of constraint errors among the soft layout constraints, i.e., the solution closest to the user''s original intent. Conversely, the layout algorithm detects the under-constrained subproblems that adversely affect the solution layout. It adds the minimal number of constraints required to achieve the fully specified layout problem that is closest to the user''s input. The second contribution is the creation of an intuitive direct manipulation user interface that lets users create the aforementioned class of general constrained layout problems. It hides the complexity of the constraint system and avoids the usability problems that have plagued constraint drawing applications. It eliminates the need of document description languages and manually-created layout templates. In the evaluation, we show that the best state-of-the-art specialized table layout algorithms do not outperform the general ICBM layout algorithm by any significant margin.

Der volle Inhalt der QuelleThe main objective of the thesis work is to define and explain the differential behavior of hematite and silicates using more selective reagents in the reverse flotation of iron ore slimes. The proposed methodology is based on using the effects of flotation reagents to increase the recovery of fine particles from iron ore processing tailings. Spectroscopic and electrokinetic methods will make it possible to understand the difference in hydration of the mineral surface. Laboratory-scale flotation tests and molecular modeling of the mechanism of interaction between the collectors and the surface of quartz and hematite will also be carried out. Pilot tests will validate the results obtained in this multi-scale thesis work

In this thesis we describe an automatic human interest detector that uses speech, physiology, body movement, location and proximity information. The speech features, consisting of activity, stress, empathy and engagement measures are used in three large experimental evaluations; measuring interest in short conversations, attraction in speed dating, and understanding the interactions within a focus group, all within a few minutes. In the conversational interest experiment, the speech features predict about 45% of the variance in self-reported interest ratings for 20 male and female participants. Stress and activity measures play the most important role, and a simple activity-based classifier predicts low or high interest with 74% accuracy (for men). In the speed-dating study, we use the speech features measured from five minutes of conversation to predict attraction between people. The features predict 40% of the variance in outcomes for attraction, friendship and business relationships. Speech features are used in an SVM classifier that is 75%-80% accurate in predicting outcomes based on speaking style. In the context of measuring consumer interest in focus groups, the speech features help to identify a pattern of behavior where subjects changed their opinions after discussion. Finally, we propose a prototype wearable 'interest meter' and various application scenarios. We portray a world where cell phones can automatically measure interest and engagement, and share this information between families and workgroups.

We studies two examples of polytope slices, hypersimplices as slices of hypercubes and edge polytopes. For hypersimplices, the main result is a proof of a conjecture by R. Stanley which gives an interpretation of the Ehrhart h*-vector in terms of descents and excedances. Our proof is geometric using a careful book-keeping of a shelling of a unimodular triangulation. We generalize this result to other closely related polytopes. We next study slices of edge polytopes. Let G be a finite connected simple graph with d vertices and let PG C Rd be the edge polytope of G. We call PG decomposable if PG decomposes into integral polytopes PG+ and PG- via a hyperplane, and we give an algorithm which determines the decomposability of an edge polytope. Based on a sequence of papers by Ohsugi and Hibi, we prove that when PG is decomposable, PG is normal if and only if both PG+ and PG- are normal. We also study toric ideals of PG, PG+ and PG-. This part is joint work with Hibi and Zhang.

Der volle Inhalt der QuelleAtt använda presentationsprogram som PowerPoint eller Keynote för att stödja föreläsningar och presentationer har blivit allestädes närvarande både i akademin och industrin. Att utforma visuella bilder av presentationsmaterial är emellertid en tidskrävande och mödosam uppgift; upprepade steg krävs för att välja mallar, organisera objekt och optimera layouter. För att underlätta dessa mödosamma arbeten och låta användarna fokusera på att förbereda innehållet i presentationer presenterar vi SmartPPT, ett ramverk som stöder den automatiska generationen av presentationsbilder från en textvy. Vi byggde en Recommender System-modell inuti ramen som kunde plocka upp bildmallar för inmatning av textrutor. För att testa dess funktionalitet och effektivitet genomfördes två uppsättningar av användarstudieprocedurer och visade att SmartPPT är tidseffektivt för att generera bilder och användarna blev nöjdare jämfört med när man gjort handgjorda bilder eller använt PowerPoint-föreslagna mallar.

E values of the potatoes increased with increasing frying time and microwave power level. The potatoes with the highest oil content were found to be the ones that were fried in the hazelnut oil. The optimum condition was found as frying at 550W microwave power level, for 2.5 minutes in sunflower oil. The potatoes that were fried at the optimum condition were determined to have lower oil contents compared to the ones fried conventionally.In the second part of the study, osmotic dehydration was applied prior to microwave frying process in order to reduce oil uptake and to evaluate the effect of osmotic dehydration with microwaves on quality of fried potatoes. The process was optimized by using both Taguchi Technique and Response Surface Methodology. Microwave power level (400W, 550W and 700W), frying time (1.5, 2.0, 2.5 minutes) and osmotic dehydration time (15, 30, 45 minutes) were the parameters used in the study.

E value of potatoes increased with increasing frying time and microwave power level. Dehydration of potatoes osmotically prior to frying reduced the oil content of fried potatoes. The optimum condition was found as frying at 400 W microwave power level for 1.5 min after 30 min of osmotic dehydration time according to Taguchi Technique. Microwave power level and frying time were the same as Taguchi Technique but osmotic dehydration time was 39 min for the optimum condition found using response surface methodology.

Der volle Inhalt der QuelleKvicklerskred är sällsynta men leder ofta till stor skada för samhället. Dessa skred är komplexa och orsaken till utlösandet av skredet är svårt att identifiera då bevisen förstörs under händelseförloppet. Detta leder till att olika teorier om orsaken av kvicklerskred kan variera från samma information. Det är också svårt att beräkna skredets omlopp i efterhand den vanliga beräkningsmetoden baseras på idealplastiska samband, något som inte går att applicera på kvicklera. Målet med denna studie var att konstruera ett felträd som underlättar riskidentifiering och riskanalyser av kvicklerskred. Målet var även att utvärdera användandet av felträdet i en byggnadsprocess, framförallt under förstudien och under projekteringsskedet. Osäkerheter inom området kräver en försiktig arbetsmetod när kvicklera finns i områden. Att använda sig av ett felträd för kvicklerskred i en riskhantering skulle kunna minska risken för ett skred och samtidigt öka systemförståelsen över fenomenet. Två fallstudier gjordes med det konstruerade felträdet, under dessa fältstudier gjordes även beräkningar med två avancerade beräkningsmetoder som tar hänsyn till det töjningsmjukande beteendet hos kvicklera. Användningav ett kvalitativt felträd i kombination med beräkningsmetoder möjligör en utvärdering av isolerade händelser som i slutändan kan leda till ett kvicklerskred. Möjligheten av att studera isolerade händelser kan underlätta en implementering av mer avancerade beräkningsmetoder i ett tidigt skede och på så vis förutse och förhindra kvicklerskred.

Der volle Inhalt der QuelleNetwork slicing is a cornerstone in the conception and deployment of enriched communication services for the new use cases envisioned and supported by the new 5G architecture.This document makes emphasis on the challenge of the network slicing isolation and security management according to policy. First, a novel access control model was created, that secures the interactions between network functions that reside inside the 5G system. Then, the management of the interactions between network slices was addressed. We coin the concept of network slice chains, which are conceived after security constraint validation according to policy. Lastly, a method to quantify isolation was developed, permitting to find out how well isolated a communication service is, which is offered via network slices. This enables network operators and customers to measure the isolation level and improve the configuration of the network slices so the isolation level can be enhanced. These components establish a solid framework that contributes to secure, vertically, the communication services of a 5G network and assess how secure they are with respect to their interactions and isolation

Inicialmente, foi realizada a caraterização físico-química da matéria prima que foi submetida ao processo de secagem em escala piloto, a 40 ºC, 50 ºC e 60 ºC, com termopares inseridos no produto monitorando sua temperatura, a velocidade do ar de secagem foi de 4 mos-1. Com a cinética de secagem e a temperatura interna da fatia foi possível validar o modelo de difusão baseado na 2a Lei de Fick e Fourier. Para este propósito, foram medidas durante o processo: as isotermas de sorção ajustadas ao modelo do GAB permitindo estimar a umidade de equilíbrio (Xe), 1.76 [g H2O/100g d.b.] a 60 ºC e 10 % de umidade relativa (RH) e as propriedades físicas e termofísicas (k, Cp, ?) para serem inseridas no modelo. Consideraram-se cinco casos: i) Propriedades termofísicas constantes; ii) Variáveis; iii) Estimativa do coeficiente de transferência de massa (hm) de calor (h) e difusividade efetiva (De) parâmetros importantes que controlam a taxa de secagem, 134 Wom-2oK-1, 4.91x10-5 m-2os-1 e 3.278x10-10 mos-2 para uma temperatura de 60 ºC, respectivamente; iv) Estimativa do De como função do teor de umidade (M) apresentando um comportamento polinomial de terceira ordem; v) O encolhimento teve influência no modelo matemático, em especial nas primeiras três horas de secagem, a espessura da banana verde experimentou uma redução de (30.34 ± 1.29) %, encontrando dois períodos de taxa de secagem decrescentes (DDR I e DDR II), os De estimados para estes dois períodos foram 3.28x10-10 mos-2 e 1.77x10-10 mos-2, respectivamente. As simulações no COMSOL Multiphysics foram possíveis de serem realizadas através dos dados estimados pelo modelo matemático.
