Abstract:
Gender classification is growing in popularity due to the variety of fields in which it can be used. It can be employed in various fields, including criminal investigations and security and authentication services. Gender Classifying speech for different speakers is still a demanding and challenging task for recognizing overlapped speech and building a robust prediction model. The paper provides a gender classification system that uses Independent Component Analysis (ICA) and several machine learning algorithms to identify mixing and de-mixing speech signals. ICA is employed to separate the mixed signal into their source signals. The system consists of two stages: the first stage is the mixing and separating process for signals. The second stage involves combining feature extraction and constructing a classification model to determine whether a signal is male or female based on its acoustic attributes. The system will evaluate the efficacy and significance of machine learning algorithms for selecting the optimal method to identify the speaker's gender with the most excellent efficiency and accuracy. Experimentation shows that the best accuracy value for an SVM model with mixing speeches is 87.1 %, and the best accuracy value for a Neural Net and SVM model with de-mixing speeches is 97.8 %.

Abstract:
This study investigated the types of code mixing used in one of teenage magazines in Indonesia, namely Aneka Yess! magazine. The research question was “what types of code mixing used in Aneka Yess! magazine”. The objective of this study was to find out the types of code mixing used in Aneka Yess! magazine, especially in “Palls Issue” rubric. The design of this study was descriptive qualitative. The techniques of data collection were: 1) collected the magazine during a month which consisted of two editions, namely 14 – 27 March dition, and 28 March – 10 April edition, 2) decided the rubric as an object of the study, 3) read the rubric, 4) underlined English code mixings, 5) identified the forms of code mixing. The result of this study showed that there were five forms of code mixings that used in the magazine, namely code mixing of word insertion that consist of 64 data, phrase insertion consist of 29 data, clause insertion consist of 10 data, reduplication insertion consist of 1 data, and idiom insertion consist of 4 data. The code mixings in word insertion was most frequently used in the magazine rather than the other types of code mixings, while the most rarely used was code mixing in reduplication insertion. It can be concluded that the using of code mixing was influenced by the capability or the knowledge of the speaker or interlocutor in using English language.

Abstract:
The mixing of scalar mesons is introduced into the baryon-baryon system in the chiral SU(3) quark model to further dynamically investigate the Di-omega state by using the same parameters as those in reasonably describing the experimental hyperon-nucleon and nucleon-nucleon scattering data. Two different mixings of scalar mesons, the ideal mixing and 19° mixing, are discussed, and compared with no mixing. The results show that it is still deeply bound state if 19° mixing is adopted, the same as those of no mixing. However, for ideal mixing, the binding energy is reduced quite a lot, yet it is still a bound state.

In the context of a typical model for fermion mass matrices, possibly based on the horizontal U (2) symmetry, we explore the effect of the type II seesaw mechanism on lepton mixings. We find that the combined contribution of type I and type II terms is able to explain the large but not maximal 1-2 mixing and the near maximal 2-3 mixing, while the 1-3 mixing angle is predicted to be small.

Code mixing (or transitioning from one code arrangement to another) is one of the hottest topics in contemporary linguistics. Kodlar aralashuvi is the transliteration of the English term code mixing (or code-switching), which first appeared in 1970s English linguistics. Prior to the use of this term, R. Yakobson drew attention to this phenomenon: “Any general code is multi-form, it is a hierarchical (stepped) set of different subcodes freely chosen by the speaker according to the function of the message, the relationship between the addressee and the interlocutors.”

Abstract:
In mainland China, previous studies have shown that Chinese-English code-mixing is gaining wide popularity while very limited researches focus on the public attitudes towards Chinese-English code-mixing. This paper therefore investigates the general perception of Chinese-English code-mixing in mainland China, specifically whether code-mixing is viewed favorably or unfavorably. By conducting online questionnaires which mainly examine the English proficiency of the respondents, their code-mixing usages and their attitudes towards code-mixing in mainland China, this paper aims to find out whether different types of code-mixings would lead to different attitudes of respondents, moreover, whether there would be a certain code-mixing type which is particularly liked or disliked. This paper illustrates the idea of Bhatia and Ritchie (2012)- “four factors determining language choice and mixing on the part of the bilingual”. Furthermore, this paper contends to analyze the topic by considering the aspects of individual and the social level in terms of psychology, history, education and politics (Bhatia & Ritchie, 2012).

Abstract:

The thesis is dealing with mixing processes havingapplication to ground improvement by deep mixing. The mainobjectives of the thesis is to make a contribution to knowledgeof the basic mechanisms in mixing binding agents into soil andimprove the knowledge concerning factors that influence theuniformity of stabilised soil.

A great part of the work consists of a literature surveywith particular emphasis on literature on the processindustries. This review forms a basis for a profounddescription and discussion of the mixing process and factorsaffecting the process in connection with deep mixingmethods.

The thesis presents a method for a simple field test for thestudy of influential factors in the mixing process. A number offactors in the installation process of lime-cement columns havebeen studied in two field tests using statistical multifactorexperiment design. The effects of retrieval rate, number ofmixing blades, rotation speed, air pressure in the storagetank, and diameter of the binder outlet on the stabilisationeffect and the coefficient of variation determined byhand-operated penetrometer tests for excavated lime-cementcolumns, were studied.

The literature review, the description of the mixingprocess, and the results from the field tests provide a morebalanced picture of the mixing process and are expected to beuseful in connection to ground improvement projects and thedevelopment of mixing equipments.

The concept of sufficient mixture quality, i.e. theinteraction between the mixing process and the mechanicalsystem, is discussed in the last section. By means ofgeostatistical methods, the analysis considers thevolume-variability relationship with reference to strengthproperties. According to the analysis, the design values forstrength properties depends on the mechanical system, the scaleof scrutiny, the spatial correlation structure, and the conceptof safety, i.e. the concept of sufficient mixture quality isproblem specific.

Abstract:
PEPT (positron emission particle tracking) is a technique for tracking a small radioactive tracer in Lagrangian co-ordinates. The technique was used to study the flow patterns of non-Newtonian CMC (Carboxy Methyl Cellulose) solutions inside a vessel agitated by an axial flow impeller. The 'non-intrusive' PEPT technique uses two position-sensitive detectors to track a radioactive particle in space and time. The particle is labelled with a positron emitting isotope. Once emitted from the nucleus a positron annihilates with an electron releasing energy in the form of two 511 keV back-to-back gamma-rays travelling in opposite directions, 180 degrees apart. The tracer particle is introduced into the stirred vessel which is mounted between the two detectors of the positron camera. Three axial flow impellers produced by Lightnin Mixers Ltd were used to carry out the experiments. Results showed that the discharge from the three impellers was radial when agitating non-Newtonian viscous solutions of CMC. Trajectory analysis was used to compare the performance of the impellers using the agitation index and the efficiency of circulation. A limited number of experiments was carried out to compare the effect of baffles on the circulation of the fluids in a mixing tank. The results showed that mixing of these non-Newtonian liquids in an unbaffled tank is better than in a baffled tank when using axial flow impellers. Other experiments were carried out to suspend solid particles in viscous fluids. Results showed that the minimum speed required to suspend large particles is lower than that required to suspend small particles. There are many correlations and models in the literature to determine the minimum speed required to suspend all the particles in a fluid; some of these correlations and models were compared with experimental results from this work. The correlation of Zweitering (1958) agreed with experimental data after modification. The Geisler et al. (1993) model agreed with the data provided that the power consumption is correctly substituted. The last part of this work concerned the flow of non-Newtonian viscous materials through industrial equipment. Yoghurt was chosen as the test fluid as one of the companies sponsoring this project was Eden Vale, a yoghurt manufacturer. A method was proposed using rheological measurements to simulate the flow through the dispensing pipeline and distributing nozzles; this method allows the designer to predict the final properties of yoghurt after passing through the paching head. Measurements were also carried out to determine the final gel structure of yoghurt in the delivery pots. This data of this thesis is useful in designing stirred tanks when non-Newtonian fluid is present, either for agitation or when suspending solids. Also, a method was provided to design yoghurt manufacturing line.

Abstract:
In order to increase our understanding of magma mixing processes and their impact on the geochemical evolution of silicate melt we present in the following works, the first set of experiments performed using natural basaltic and rhyolitic melts. In particular, we investigate the interplay of physical dynamics and chemical exchanges between these two melts using time-series mixing experiments performed under controlled, chaotic, dynamical conditions. The variation of major and trace elements is studied in detail by electron microprobe (EMPA) and Laser Ablation ICP-MS (LA-ICP-MS) and the time-evolution of chemical exchanges during mixing is investigated. Using the concentration variance as a proxy to measure the rate of chemical element homogenization in time, a model to quantify chemical element mobility during chaotic mixing of natural silicate melts is proposed. The morphology of mixing patterns at different times is quantified by measuring their fractal dimension and an empirical relationship between mixing time and morphological complexity is derived. The complexity of mixing patterns is also compared to the degree of homogenization of chemical elements during mixing and empirical relationships are established between the fractal dimension and the variation of concentration variance of chemical elements in time. Finally we discuss the petrological and volcanological implications of this work.
Um unser Verständnis über die Prozesse bei der Vermischung von Magmen und dessen Auswirkungen auf die geochemische Entwicklung von Silikatschmelzen zu verbessern, werden in dieser Arbeit erstmalig eine Reihe von „Magma Mixing“ Experimenten vorgestellt, in der natürliche Basalte und Rhyolite verwendet werden. In dynamischen Zeitreihen-Mischungsexperimenten, die unter kontrollierten, chaotischen, dynamischen, Bedingungen abliefen, wurde vor allem das Zusammenspiel der physikalischen Prozessen durch das mechanische Vermengen zweier Schmelzen und der resultierenden chemischen Austauschreaktionen durch Diffusion an den Grenzflächen zwischen diesen beiden Schmelzen untersucht. Die Variation von Haupt- und Spurenelementen wurde mittels Elektronen-Mikrosonde (EMPA) und Laser Ablation ICP-MS (LA-ICP-MS) im Detail untersucht und zusätzlich konnte die zeitliche Entwicklung des chemischen Austauschs während des Mischungsvorgang dargestellt werden. Die Varianz der Konzentration einzelner Elemente über die Grenzflächen zwischen Basalt und Rhyolit hinweg wurde als Proxy verwendet, um die Homogenisierungsrate der chemischen Elemente bezogen auf die Zeit zu bestimmen. Dies wird als Modell vorgeschlagen, mit dem die Mobilität chemischer Elemente während chaotischem Mischens von natürlichen Silikatschmelzen quantifiziert werden kann. Im Weiteren wurde mit Hilfe von Fraktalanalyse die Morphologie der Mischungsmustern zu unterschiedlichen Zeiten quantifiziert und eine empirische Beziehung zwischen Mischzeit und morphologischer Komplexität abgeleitet. Die Komplexität der Mischungsmuster wurde zudem mit dem Grad der Homogenisierung der chemischen Elemente während des Mischens verglichen. Dadurch konnten empirische Beziehungen zwischen der fraktalen Dimension von Mischungsmorphologien und der zeitlichen Variation der Konzentration von chemischen Elementen abgeleitet werden. Im Laufe dieser Arbeit werden zudem die petrologischen und vulkanologischen Auswirkungen diskutiert.

The hi-end tools available to today's sound designers give them almost limitless control over audio processing. Devices such as Yamaha's new digital mixers and Digidesign's Pro-Tools computerized editing workstations allow users in a small studio to accomplish tasks which would have required racks full of gear only seven years ago in a professional studio. However, the evolution of the interfaces used with these systems have not kept pace with the improvements in functionality. With all of their complexity, the new digital mixing consoles still look like the old analog mixers, with the addition of an LCD screen. This thesis will introduce a new type of concept called Multi-Modal Mixing that aims to enhance current systems and point to a new standard of audio control.

Abstract:
Seawater intrusion presents one of the most unique and ubiquitous groundwater problems in the field of hydrogeology. Its complex boundary conditions coupled with variable density flow results in non-uniform flow which lead to non-trivial mixing dynamics. The mixing of fresh and saline waters in the subsurface is known to play a key role in an array of geochemical reactions. Such reactions include the dissolution and precipitation of calcite which shape the coastal landscape over millennia, as well as reactions associated to anthropogenic contamination of coastal groundwater such as nitrogen reduction or iron oxide precipitation which can act to limit the fluxes of harmful pollutants to vulnerable near shore marine ecosystems. In addition to reactions, understanding the mixing mechanisms is crucial to predicting the movement of the saltwater wedge and the size of the salt-freshwater interface. This has direct implications on the management of fresh groundwater reserves and its risk to salinization. In this thesis we focus on understanding the influence variable density flow on mixing and the spatial distribution of enhanced geochemical activity along the saline-freshwater interface. First, we look to see the impact of heterogeneity on mixing and reaction for fast calcite dissolution. We find that heterogeneity permits reactions to occur over a greater area of the mixing zone due to enhanced mixing rates than would otherwise be permitted in homogeneous media. Furthermore, we observe unique patterns of enhanced localized reactivity that strongly deviate from the homogeneous case. Our study suggests that karst topology in coastal aquifers may be strongly linked to non-uniform flow induced by variable density flow and strongly linked to the type of heterogeneity present. Since initial stages of karst development are known to dictate the evolution of cave systems and conduits, we hypothesize that heterogeneity plays an integral role in its propagation. Second, we study mixing across the salt-freshwater interface and the influence of compression caused by the flow of freshwater towards the saltwater body. In the absence of transient effects and heterogeneity, we find that mixing interface grow via transverse dispersion until some critical distance at which point it begins to recompress due to accelerating flow resulting from a decrease in area between the confining unit and the interface. Using a modified Glover solution to define the mixing interface, we are able to capture the velocity change along the interface from which a stretching rate (acceleration) can be deduced. We find that the behaviour of interface compression can be well-approximated by assuming a local Bachelor scale, which defines the equilibrium between dispersive growth and compression due to accelerating flow. Finally, we establish a new method to study fast mixing-dependent reactions across the salt-freshwater interface. Our findings lead us to the use of luminol chemiluminescence, which allows for the direct visualization of reaction rates along the saline-freshwater interface. Unlike conservative studies of mixing in sand tank, we bypass the need for complex image analysis techniques required to resolve local concentration gradients needed to evaluate mixing metrics. Results from experiments performed under both steady state and transient conditions consistently confirm local reaction hotspots at both the interface toe and at the head of the interface, which we attribute to stagnation point flow and accelerating flow respectively. Evaluation of the interface during the transient advance and retreat were also able to capture unique reactive behaviours that capture a shift in mixing behaviour due to a change in the flow field across the mixing zone
La intrusión de agua de mar presenta uno de los problemas más singulares y omnipresentes de aguas subterráneas en el campo de la hidrogeología. Sus complejas condiciones de contorno junto con un flujo de densidad variable dan como resultado un flujo irregular y, consecuentemente, provocando una dinámica de mezcla no trivial. La mezcla de agua dulce y salada en el subsuelo juega un papel clave en una serie de reacciones geoquímicas, tal como la disolución y precipitación de la calcita, que ha dado forma al paisaje costero durante milenios. También controla reacciones asociadas a la contaminación antropogénica de las aguas subterráneas costeras, tal como la reducción de nitrógeno o la precipitación de óxido de hierro,que pueden actuar para limitar los flujos de elementos contaminantes. Dichos elementos son nocivos para las zonas vulnerables cercanas a la costa, como los ecosistemas marinos. Además de las reacciones, comprender los mecanismos de mezcla es crucial para predecir el movimiento de la cuña de agua salada y el tamaño de la interfaz que separa el agua salada de la dulce. Esto tiene implicaciones directas en la gestión de las reservas de agua dulce subterránea y su riesgo de salinización. En esta tesis nos enfocamos en comprender la influencia del flujo de densidad variable en el proceso de mezcla y la distribución espacial de la actividad geoquímica (mejorada) sobre la interfaz agua dulce y salada. Primero, buscamos ver el impacto de la heterogeneidad hidráulica en la mezcla y reacción para una rápida disolución de la calcita. Encontramos que tal heterogeneidad permite que se produzcan reacciones en un área mayor de la zona de mezcla debido a velocidades de mezcla mejoradas respecto de las que serían posibles en medios homogéneos. Además, observamos patrones únicos de reactividad localizada mejorada que se desvían fuertemente del caso homogéneo. Nuestro estudio sugiere que la topología kárstica en los acuíferos costeros puede estar fuertemente ligada a un flujo no uniforme inducido por un flujo de densidad variable y fuertemente vinculado al tipo de heterogeneidad presente. Dado que se sabe que las etapas iniciales del desarrollo kárstico dictan la evolución de los sistemas de cuevas y conductos, planteamos la hipótesis de que la heterogeneidad juega un papel integral en su propagación. En segundo lugar, estudiamos el proceso de mezcla que se da en la interfaz de agua dulce y salada y la influencia de la compresión causada por el flujo de agua dulce hacia el cuerpo de agua salada. En ausencia de efectos transitorios y heterogeneidad, encontramos que la interfaz de mezcla crece a través de la dispersión transversal hasta una distancia crítica en cuyo punto comienza a comprimirse, debido al flujo acelerado resultante de una disminución en el área entre la unidad confinante y la interfaz. Usando una solución Glover modificada para definir la interfaz de mezcla, podemos capturar el cambio de velocidad a lo largo de la interfaz de la cual se puede deducir una tasa de estiramiento (aceleración). Encontramos que el comportamiento de la compresión de la interfaz se puede aproximar bien asumiendo una escala de Bachelor local, que define el equilibrio entre el crecimiento dispersivo y la compresión debido al flujo acelerado. Finalmente, establecemos un nuevo método para estudiar reacciones rápidas dependientes de la mezcla a través de la interfaz sal-agua dulce. Nuestros hallazgos nos llevan al uso de quimioluminiscencia de luminol, que permite la visualización directa de la distribución espacial de la tasa de reacción a lo largo de la interfaz agua dulce-salada. A diferencia de la práctica más habitual en estudios de mezcla en tanques de arena, que típicamente utilizan trazadores no reactivos, evitamos aquí la necesidad de resolver gradientes de concentración para computar métricas de mezcla. Los resultados de los experimentos, realizados tanto en condiciones estacionarias como transitorias, confirman consistentemente la generación de puntos calientes de reacción local, tanto en la cuña como en la cabeza de la interfaz, que atribuimos al estancamiento y aceleración del flujo, respectivamente. La evaluación de la interfaz durante el avance y retroceso transitorio también pudo capturar comportamientos reactivos únicos que capturan un cambio en el comportamiento de mezcla debido a un cambio en el campo de flujo a través de la zona de mezcla.

Abstract:
Initiation and maintenance of motion within a pulp suspension is necessary for effective mixing. This requires imposition of forces greater than the network strength and depends on suspension rheology once motion begins. As pulp suspensions display non-Newtonian and solid-like behaviour, studies were conducted using profiled rotors which imposed stress within the body of suspensions contained in cylindrical devices. A concentric cylinder device capable of high torques (85 N-m) and high rotational speeds (524 rad/s) was built to study pulp suspension dynamic behaviour. Most work used a profiled rotor 0.1 m in diameter with baffled housings 0.13 and 0.22 m in diamter. The yield stress of low consistency pulp suspensions were measured with a Haake RV12 Ro-tovisco concentric cylinder viscometer. Semi-bleached kraft pulp was used throughout the study. Some tests were made with stone groundwood and thermomechanical pulps. Yield stress measurements were made for nylon and Spectra-900 fibre suspensions. The yield stress of pulp suspensions, ty, have been measured and correlated with mass concentration (Cm) and volumetric concentration (Cv) over the range 0.4 ≤ Cm(%) ≤ 33. It was found that because of increasing gas content that correlations developed using the mass concentration were inaccurate above approximately 20% Cm. Correlations developed using the volumetric concentration were accurate over the full range tested. For a West-Coast semi-bleached kraft pulp, ty(Pa) = 1.40CV(%)²ֹ⁷². Once rotor motion was initiated, pulp suspensions exhibited two distinct regimes of behaviour. The first was a tangential-cavity regime in which predominantly tangential motion grew to fill the chamber as shear rate increased. When motion reached the outer housing wall a flow transition occurred, likely triggered by flow interaction with the housing baffles. The subsequent post-transition regime was characterized by radial and axial flow that effectively mixed the suspension on both the macroscale and fibre-scale. The flow transition appeared to be what earlier workers reported as the onset of "fluidization". During tangential-cavity flow, phase segregation occurred. Gas present in the suspension collected around the rotor and reduced momentum transfer from the rotor to the suspension. This caused the torque for the pulp suspension to fall below that for water at the same rotational speed, and the cessation of flow development in the chamber. If sufficient momentum transfer was attained to initiate post-transition flow, the chamber contents became effectively mixed. The torque could still fall below that of water depending on the effective density of the suspension in the rotor vicinity.

Cereceda, Luis. "Mixing graph colourings." Thesis, London School of Economics and Political Science (University of London), 2007. http://etheses.lse.ac.uk/131/.

Full text
Abstract:
This thesis investigates some problems related to graph colouring, or. more precisely. graph re-colouring. Informally, the basic question addressed can be phrased as follows. Suppose one is given a graph G whose vertices can be properly k-coloured. for some k > 2. Is it possible to transform any k-colouring of G into any other by recolouring vertices of G one at a time, making sure a proper k-colouring of G is always maintained? If the answer is in the affirmative, G is said to be k-mixing. The related problem of deciding whether, given two k-colourings of G7 it is possible to transform one into the other by recolouring vertices one at a time, always maintaining a proper k-colouring of G, is also considered. These questions can be considered as having a hearing on certain mathematical and "real-world" problems. In particular, being able to recolour any colouring of a given graph to any other colouring is a necessary pre-requisite for the method of sampling colourings known as Glauber dynamics. The results presented in this thesis may also find application in the context of frequency reassignment: given that the problem of assigning radio frequencies in a wireless communications network is often modelled as a graph colouring problem. the task of re-assigning frequencies in such a network can be thought of as a graph recolouring problem. Throughout the thesis. the emphasis is 011 the algorithmic aspects and the computational complexity of the questions described above. In other words, how easily. in terms of computational resources used, can they be answered? Strong results are obtained for the k = 3 case of the first question, where a characterisation theorem for 3-mixing graphs is given. For the second question. a dichotomy theorem for the complexity of the problem is proved: the problem is solvable in polynomial time for k < 3 and PSPACE-complete for k > 4. In addition, the possible length of a shortest sequence of recolourings between two colourings is investigated, and an interesting connection between the tractability of the problem and its underlying structure is established. Some variants of the above problems are also explored.
