The Effect of Thermal Treatment on the Engineering Properties of Clays
Creators: name: Laughlin, George R.
Publisher: name: Kentucky Transportation Center, University of Kentucky
Year: 1959
Subjects: subject: Transportation Engineering

description: Of the cohesive soils the property of plasticity is usually of the most concern to the engineer. The clay minerals rather than the clay size material present in a soil determine the degree and magnitude of plastic properties. In turn, the plasticity of the clay minerals varies according to their mineralogy and particle size. Of the various types of clay minerals present in a soil, only kaolinite, illite and montmorillonite occur in sufficient abundance to be of general engineering significance.  Much prior work has been performed to alter these plastic properties of clay soils. This has been accomplished in some instances by the use of solidifiers and cationic modifiers. Although these methods have proved effective in many instances; they have shown definite difficulties and limitations. All of these efforts have been directed toward one principal objective: soil stabilization -- that is, rendering clay particles into larger aggregates or otherwise rendering them non-plastic. One such method which may be feasible in the near future is thermal treatment. Perhaps ultimately a technique may be devised for transforming soil into a continuous vitreous roadway base or pavement. Although such a method is still visionary, there are considerable possibilities at the present for more limited techniques of thermal treatment of soils.  Since the noncohesive components of a soil have rather definite physical properties in relation to moisture contents and have high heats of transformation, it seems logical to approach the method of thermal treatment as a means of stabilization by treating materials having physical properties which vary greatly in relation to moisture content but which have low heats of transformation.  The purpose of this study was to further explore the effects of thermal treatment on the physical properties and mineralogy of the clay minerals: kaolinite, illite and montmorillonite.

description: Environmental policies make a difference in shaping producers' choices among dairy production technologies, the sizes and locations of their dairies, and even which dairies ultimately survive. Induced policy innovation means producers reacting to policies, and policies, in turn, being shaped by their effects. Profiles of experiences with environmental compliance in Texas and Florida were analyzed. Results demonstrate that the timing and sequencing of policy signals make a difference in compliance behavior and options. Furthermore, ex ante assessments of the costs of environmental compliance are challenging to carry out, and consequently can undermine the policy goal of maintaining the maximum number of options for compliance.

description: In our globalizing world, audiovisual products are understandably considered tools that advertise their original language and culture. Most societies do not stand any interference from the outside, especially if it considerably opposes the socio-cultural norms. Translation is a practice of cross-cultural communication which most often complies with the socio-cultural guidelines and norms of the recipient society. However, translated products might face resistance as they can be regarded threatening and hostile by the ruling gatekeepers. Given the dramatic disparities between most languages and cultures, translators are not the only decision-makers and other agents have pivotal roles in the process of adapting the translated product to the dominant conventions and socio-cultural norms. This paper aims at shedding some light on the role which agents play in the process of dubbing, both for public access national television and for private home distribution. The study explores the effects of preliminary and operational norms, and cultural appropriation conducted at both textual and visual levels through a method including interview data and textual analysis. The results show that foreign movies dubbed into Persian in the religious context of the contemporary Iran are strictly controlled both before the process of dubbing and during and after the process of dubbing due to a number of socio-cultural, political, and ideological considerations.

description: Metaproteomics – the characterization of proteins expressed by microbiomes – presents a range of technical challenges, from sampling to data processing and interpretation. In the iPRG 2020 study, we investigated the status of metaproteomics data analysis workflows by posing questions to the metaproteomics studies in two studies. In two phases of the study, the participants were asked to deduce the organisms or taxa in a metaproteomics sample (“What species are represented in the sample?”) and what biological phenomena have taken place (“What interactions took place between the species in the mixture?”). The outputs from these studies will be presented at the RG session at ABRF 2021.

Power supply for an electric resistance melting furnace
Creators: name: Alimadadi, Mehdi
Publisher: name: University of British Columbia
Year: 2009

description: In recent years, the field of power electronics has experienced a large growth due to the confluence of several factors. Revolutionary advances in microelectronics methods have led to the development of controllers that include linear ICs and DSPs. Moreover, advances in semiconductor fabrication technology have made it possible to significantly improve the voltage/current handling capabilities and the switching speeds of power switches. This work is intended as a pilot 400kW unit for testing in the Advanced Material and Process Engineering Laboratory (AMPEL) building. The eventual goal of this project is to produce a full size commercial unit at 2.4MW. The conventional supply for an electric resistance-melting furnace consists of a singlephase low voltage source obtained from a 60Hz transformer. This high power single-phase load is becoming increasingly unacceptable to customers and a method of transforming the load into an effective balanced three-phase equivalent is sought. In single-phase sinusoidal loads the instantaneous power pulsates at twice the source frequency but the total instantaneous power drawn by a balanced three-phase load is constant. This implies that a substantial energy requirement must be present in any converter between the two systems or an unbalanced load to the three-phase source will be presented. Among the possible solutions, an AC/DC/AC conversion was chosen. A thyristor bridge rectifier is used as the AC/DC converter and a voltage source inverter is used as the DC/AC converter. Several previous papers have been reviewed to have a better idea on designing the DCbus filter, the effect of non-sinusoidal voltage/current on the transformers, etc. Practical considerations were one the most important factors in the design and choosing of the elements.

description: In this paper we study a parametric class of stochastic processes to model both fast and slow anomalous diffusion. This class, called generalized grey Brownian motion (ggBm), is made up off self-similar with stationary increments processes (H-sssi) and depends on two real parameters alpha in (0,2) and beta in (0,1]. It includes fractional Brownian motion when alpha in (0,2) and beta=1, and time-fractional diffusion stochastic processes when alpha=beta in (0,1). The latters have marginal probability density function governed by time-fractional diffusion equations of order beta. The ggBm is defined through the explicit construction of the underline probability space. However, in this paper we show that it is possible to define it in an unspecified probability space. For this purpose, we write down explicitly all the finite dimensional probability density functions. Moreover, we provide different ggBm characterizations. The role of the M-Wright function, which is related to the fundamental solution of the time-fractional diffusion equation, emerges as a natural generalization of the Gaussian distribution. Furthermore, we show that ggBm can be represented in terms of the product of a random variable, which is related to the M-Wright function, and an independent fractional Brownian motion. This representation highlights the $H$-{\bf sssi} nature of the ggBm and provides a way to study and simulate the trajectories. For this purpose, we developed a random walk model based on a finite difference approximation of a partial integro-differenital equation of fractional type.

description: Binarization is a well-known image processing task, whose objective is to separate the foreground of an image from the background. One of the many tasks for which it is useful is that of preprocessing document images in order to identify relevant information, such as text or symbols. The wide variety of document types, alphabets, and formats makes binarization challenging. There are multiple proposals with which to solve this problem, from classical manually-adjusted methods, to more recent approaches based on machine learning. The latter techniques require a large amount of training data in order to obtain good results; however, labeling a portion of each existing collection of documents is not feasible in practice. This is a common problem in supervised learning, which can be addressed by using the so-called Domain Adaptation (DA) techniques. These techniques take advantage of the knowledge learned in one domain, for which labeled data are available, to apply it to other domains for which there are no labeled data. This paper proposes a method that combines neural networks and DA in order to carry out unsupervised document binarization. However, when both the source and target domains are very similar, this adaptation could be detrimental. Our methodology, therefore, first measures the similarity between domains in an innovative manner in order to determine whether or not it is appropriate to apply the adaptation process. The results reported in the experimentation, when evaluating up to 20 possible combinations among five different domains, show that our proposal successfully deals with the binarization of new document domains without the need for labeled data.

description: This paper investigates whether inferences drawn about a population are sensitive to the manner by which those data are obtained. It compares information obtained using participatory appraisal techniques with a survey of households randomly drawn from a locally administered census that had been carefully revised. The community map tends to include household members who do not, in fact, reside in the enumerated locality. By contrast, the revised official census is slightly more likely to exclude household members who actually lived in the surveyed area. Controlling for the survey technique, we find that the revised official census produces higher estimates of average household size and wealth but lower estimates of total village size or wealth, than the community map. Pairwise comparison of the survey techniques, holding the households constant, shows that the community map leads, on average, to higher estimates of household size and lower estimates of wealth.

subject: FOS: Computer and information sciences

description: Project evaluation and selection is a complex multi-attribute decision-making problem. With the information uncertainty and inaccuracy considered, a new model for project evaluation and selection is proposed, which combines the fuzzy analytic hierarchy process (AHP) and technique for order performance by similarity to ideal solution (TOPSIS). The hybrid method is based on interval-valued triangular fuzzy numbers. An index system for selecting the optimal project is established. The weights of criteria and sub-criteria are derived by fuzzy AHP. The relative closeness is drawn from the calculation of the distance between the alternatives and positive ideal solutions or negative ones. Also, the ranking of alternatives can be based on their relative closeness. Finally, a case study is given adopting the proposed method.

description: Over the past decade, donor-funded policies and programs designed to address undernutrition in the Global South have shifted away from agriculture-based strategies toward nutrient supplementation and food fortification programs. Given the potential benefits resulting from agriculture-based nutrition interventions, this study uses Q methodology to explore the views of a range of stakeholders from both developed and developing countries on the value of-and constraints related to-gender-sensitive, nutrition-oriented agricultural projects. The three distinct viewpoints that emerge from this exercise all support the use of agricultural strategies to improve nutrition and underline the importance of gender-sensitive approaches. The viewpoints differ, however, on the relative importance of nutrition education, the strategic use of nutrient supplementation and food fortification, and the degree to which agriculture-based approaches have an impact on nutrition. The findings indicate that there is common ground among a range of stakeholders-donors, researchers, policymakers, and program practitioners-on the benefits of agriculture and gender-sensitive strategies to improve nutrition. These areas of agreement can serve as a foundation for forging an effective integrative strategy to improve nutrition that includes gender-sensitive agricultural approaches.

description: Time and the choice of measurement time scales is fundamental to how we choose to represent information and data in finance. This choice implies both the units and the aggregation scales for the resulting statistical measurables used to describe a financial system. It also defines how we measure the relationship between different traded instruments. As we move from high-frequency time scales, when individual trade and quote events occur, to the mesoscales when correlations emerge in ways that can conform to various latent models; it remains unclear what choice of time and sampling rates are appropriate to faithfully capture system dynamics and asset correlations for decision making. The Epps effect is the key phenomenology that couples the emergence of correlations to the choice of sampling time scales. Here we consider and compare the Epps effect under different sampling schemes in order to contrast three choices of time: calendar time, volume time and trade time. Using a toy model based on a Hawkes process, we are able to achieve simulation results that conform well with empirical dynamics. Concretely, we find that the Epps effect is present under all three definitions of time and that correlations emerge faster under trade time compared to calendar time, whereas correlations emerge linearly under volume time.

description: We construct a continuum model of twisted trilayer graphene using {\it ab initio} density-functional-theory calculations, and apply it to address twisted trilayer electronic structure. Our model accounts for moiré variation in site energies, hopping between outside layers and within layers. We focus on the role of a mirror symmetry present in ABA graphene trilayers with a middle layer twist. The mirror symmetry is lost intentionally when a displacement field is applied between layers, and unintentionally when the top layer is shifted laterally relative to the bottom layer. We use two band structure characteristics that are directly relevant to transport measurements, the Drude weight and the weak-field Hall conductivity, and relate them via the Hall density to assess the influence of the accidental lateral stacking shifts currently present in all experimental devices on electronic properties, and comment on the role of the possible importance of accidental lateral stacking shifts for superconductivity in twisted trilayers.

description: We show that infinitesimal automorphisms and infinitesimal deformations of parabolic geometries can be nicely described in terms of the twisted de-Rham sequence associated to a certain linear connection on the adjoint tractor bundle. For regular normal geometries, this description can be related to the underlying geometric structure using the machinery of BGG sequences. In the locally flat case, this leads to a deformation complex, which generalizes the is well know complex for locally conformally flat manifolds. Recently, a theory of subcomplexes in BGG sequences has been developed. This applies to certain types of torsion free parabolic geometries including, quaternionic structures, quaternionic contact structures and CR structures. We show that for these structures one of the subcomplexes in the adjoint BGG sequence leads (even in the curved case) to a complex governing deformations in the subcategory of torsion free geometries. For quaternionic structures, this deformation complex is elliptic.

description: This paper uses a panel data of 347 households in Egypt to measure changes in household consumption between 1997 and 1999 and to identify causes behind the changes. Per capita consumption decreased for the households during this time and, while not dramatic, it occurred at all points along the distribution. Over the two-year period, the number of households that fell into poverty was over twice as large as the number of households that climbed out of poverty. About two-thirds of overall poverty was chronic (average consumption over time was below the poverty line), and almost half of all poor were always poor. We use quantile regression methods to identify the factors that explain total, chronic, and transitory poverty. While our analysis ably documents the extent of transitory poverty, it does not explain well the determinants of this type of poverty. The predominantly chronic nature of poverty in the sample, and our ability to identify associated characteristics, strengthens the case for targeting antipoverty interventions such as food subsidies.

Two dimensional loop shaping controller design for paper machine cross-directional processes
Creators: name: Stewart, Gregory Edward
Publisher: name: University of British Columbia
Year: 2009

description: The objective of this work is the development of a practical technique for the design of feedback controllers for the cross-directional control of paper machines. An industrial paper machine produces a wide sheet of paper which is required to be of uniform quality in terms of the weight, moisture content, and caliper (thickness). Modern machines produce a paper sheet which is up to 11 metres in width and is properly described as a two dimensional system. The direction perpendicular to the sheet travel is known as the cross-direction, and cross-directional control is implemented by arrays of up to 300 identical actuators evenly distributed across the sheet width. The sheet properties are measured by a scanning sensor at up to 2000 locations evenly spaced across the width of the moving paper sheet. A constructive, computationally inexpensive, graphical controller design technique is developed for dynamical systems that are distributed in one spatial dimension and controlled by an array of identical actuators. The feedback controller is designed using a two dimensional loop shaping technique with reference to the process model and the model uncertainty such that the spatial and dynamical bandwidth limitations of the physical system are respected. The two dimensional loop shaping design technique is then applied to the design of cross-directional feedback controllers for the paper making process. The two dimensional loop shaping approach is well-suited to address the wide variety of processes and conditions for which a cross-directional controller must perform well. The design technique is demonstrated by successfully tuning an industrial crossdirectional controller. The tuning results are confirmed by experiments with a real paper machine in a working mill.

Since they have two horizons, the inner being of Cauchy type, we focus on the problem of mass inflation and show that it occurs except when some extremal conditions are met.

description: This paper is based on community-level data from 188 villages in rural Madagascar. The survey that was conducted in 1997 made extensive use of long-term recall questions ascertaining changes during the past 10 years in rice yields, wages, population, soil fertility, and other pertinent variables of rural development. We find that—on average for all villages—the yields of irrigated rice, the major food crop, and real agricultural wages declined, while the communities expanded their upland area by nearly a quarter and experienced deteriorating fertility of their upland soils. These patterns are consistent with the wide-held belief that rural areas in Madagascar have witnessed increased poverty, economic stagnation, and a continued degradation of the natural resources. Yet, the five agroecological regions in our sample exhibit quite different patterns of rural development, and at least one of them has experienced increases in yields and wages. From a policy perspective, it is important to better understand the driving forces of such diverse rural change. The overall decline in rural wages over the past 10 years is expected to have contributed to increased poverty, food insecurity and malnutrition in rural areas, as rural wage laborers traditionally belong to the poorest of the poor in Madagascar. In this paper, we present an econometric analysis of the determinants of and interdependencies between the three components of sustainable development: economic growth, environmental sustainability, and poverty alleviation. We develop a two-stage, least-squares fixed-effect model that attempts to explain rice yields, rural migration and wages, endogenous placement of microfinance institutions, and the observed change in upland and soil fertility, with exogenous and policy variables, such as the communities' social capital, their exposure to weather risks and their access to commodity and financial markets and to public services. The paper concludes with a number of implications for policy and future research.

In particular, we consider Manin matrices of the types $B$, $C$ and $D$ introduced by A. Molev and their relation with Brauer algebras. Infinite-dimensional Manin matrices and their connection with Lax operators are also considered.

description: Modern CDMA systems are required to provide differentiated services to support heterogeneous traffic while existing rate allocation schemes are designed for homogeneous users. We propose different utility functions to adapt to distinct user QoS requirements. Our goal is to maximize the system-wide aggregated utilities. A suboptimal solution of this NP-hard nonlinear programming problem is achieved by implementing GA-SA hybrid algorithm. Simulation results verify that our scheme allocates rates in such a way that all types of services are satisfied in balance while a high throughput is still maintained therefore more types of services are accommodated in the system.

description: This paper examines the relationship between community participation and the efficacy of interventions designed to reduce poverty. We develop some simple analytics that are used to structure a review of the extant literature and motivate the analysis of the impact of participation on the efficacy of public works interventions in South Africa. These analytics suggest that because communities possess informational advantages unavailable to outsiders, community participation offers the prospect of lowering the cost of antipoverty interventions. In cases where the outcomes of interventions are difficult to measure, community participation is attractive because it is more likely to produce a set of outcomes actually desired by the community. However, this observation should not be taken to imply that these outcomes are desired by all members of the community, nor by those who finance these interventions. These arguments are supported both by a review of the extant literature and also by a multivariate analysis of the impact of community participation on public works projects in South Africa. We find that increasing community participation lowers the ratio of project to local wages, increases the labor intensity of projects that provide community buildings, roads or sewers, and lowers the cost of creating employment and of transferring funds to poor individuals. We find no evidence that community participation increases cost overruns in these projects.

description: We construct a holographic SU(2) p-wave superconductor model with Weyl corrections. The high derivative (HD) terms do not seem to spoil the generation of the p-wave superconducting phase. We mainly study the properties of AC conductivity, which is absent in holographic SU(2) p-wave superconductor with Weyl corrections. The conductivities in superconducting phase exhibit obvious anisotropic behaviors. Along $y$ direction, the conductivity $σ_{yy}$ is similar to that of holographic s-wave superconductor. The superconducting energy gap exhibits a wide extension. For the conductivity $σ_{xx}$ along $x$ direction, the behaviors of the real part in the normal state are closely similar to that of $σ_{yy}$. However, the anisotropy of the conductivity obviously shows up in the superconducting phase. A Drude-like peak at low frequency emerges in $Reσ_{xx}$ once the system enters into the superconducting phase, regardless of the behaviors in normal state.

The role of hyperfine interactions between molecular and nuclear spins is studied. Numerical solutions of the spin evolution equations are presented.

description: In this paper, an ad hoc network anonymous data forwarding method and an associated routing protocol to prevent traffic analysis is presented. This method assumes trusted closed group nodes and every node can play the role of onion relay for the anonymous data forwarding. The route discovery operation of the protocol adopts the load balancing concept. The load balancing not only improves the throughput but also helps the prevention of the traffic analysis since the load cost for camouflage traffic can be reduce and the routes change dynamically. The performance of the proposed protocol is evaluated by simulation, and compared in several major aspects with the fixed mix method for anonymous data forwarding that works over existing ad hoc routing protocol.

description: We argue that cosmic strings with high winding numbers generally form in first-order gauge symmetry breaking phase transitions, and we demonstrate this using computer simulations. These strings are heavier than single-winding strings and therefore more easily observable. Their cosmological evolution may also be very different.

description: Photoacoustic microscopy (PAM) is an emerging imaging method combining light and sound. However, limited by the laser's repetition rate, state-of-the-art high-speed PAM technology often sacrifices spatial sampling density (i.e., undersampling) for increased imaging speed over a large field-of-view. Deep learning (DL) methods have recently been used to improve sparsely sampled PAM images; however, these methods often require time-consuming pre-training and large training dataset with ground truth. Here, we propose the use of deep image prior (DIP) to improve the image quality of undersampled PAM images. Unlike other DL approaches, DIP requires neither pre-training nor fully-sampled ground truth, enabling its flexible and fast implementation on various imaging targets. Our results have demonstrated substantial improvement in PAM images with as few as 1.4$\%$ of the fully sampled pixels on high-speed PAM. Our approach outperforms interpolation, is competitive with pre-trained supervised DL method, and is readily translated to other high-speed, undersampling imaging modalities.
TARGETING POVERTY THROUGH COMMUNITY-BASED PUBLIC WORKS PROGRAMS: A CROSS-DISCIPLINARY ASSESSMENT OF RECENT EXPERIENCE IN SOUTH AFRICA

description: Since the transition to democracy, South African public works programs are to involve community participation, and be targeted to the poor and women. This paper examines the targeting performance of seven programs in Western Cape Province, and analyzes the role of government, community-based organizations, trade unions, and the private sector in explaining targeting outcomes. These programs were not well-targeted geographically in terms of poverty, unemployment, or infrastructure. Within localities, jobs went to the poor and unemployed, though not always the poorest. They did well in reaching women, despite local gender bias. Targeting guidelines of the state are mediated by diverse priorities that emerge in programs with multiple objectives, local perceptions of need and entitlement, and competing voices within civil society.

description: The High-Energy Storage Ring (HESR) of the future International Facility for Antiproton and Ion Research (FAIR) at GSI in Darmstadt is planned as an antiproton synchrotron and storage ring in the momentum range from 1.5 to 15 GeV/c. An important feature of this new facility is the combination of phase space cooled beams with dense internal targets (e.g. pellet targets), resulting in demanding beam parameter of two operation modes: high luminosity mode with peak luminosities up to 2*10^32 cm-2 s-1, and high resolution mode with a momentum spread down to 10^-5, respectively. To reach these beam parameters very powerful phase space cooling is needed, utilizing high-energy electron cooling and high-bandwidth stochastic cooling. The effect of beam-target scattering and intra-beam interaction is investigated in order to study beam equilibria and beam losses for the two different operation modes.

description: Pulse Doppler radars suffer from range-Doppler ambiguity that translates into a trade-off between maximal unambiguous range and velocity. Several techniques, like the multiple PRFs (MPRF) method, have been proposed to mitigate this problem. The drawback of the MPRF method is that the received samples are not processed jointly, decreasing signal to noise ratio (SNR). To overcome the drawbacks of MPRF, we employ a random pulse phase coding approach to increase the unambiguous range region while preserving the unambiguous Doppler region. Our method encodes each pulse with a random phase, varying from pulse to pulse, and then processes the received samples jointly to resolve the range ambiguity. This technique increases the SNR through joint processing without the parameter matching procedures required in the MPRF method. The recovery algorithm is designed based on orthogonal matching pursuit so that it can be directly applied to either Nyquist or sub-Nyquist samples. The unambiguous delay-Doppler recovery condition is derived with compressed sensing theory in noiseless settings. In particular, an upper bound to the number of targets is given, with respect to the number of samples in each pulse repetition interval and the number of transmit pulses. Simulations show that in both regimes of Nyquist and sub-Nyquist samples our method outperforms the popular MPRF approach in terms of hit rate.
Distributed Rate and Power Control for CDMA Uplink

description: We consider a distributed CDMA system in which mobiles are capable to control their transmission rate and power based on their radio conditions. Each mobile is assumed to be myopic, that is, his solitary goal is to maximize the payoff which is the difference between the effective throughput and the price that the system charges for the received power on behalf of the mobile. We prove that the distributed system converges to a Nash Equilibrium such that users near the base station transmit in the &I1 rate while farther users transmit in the fill power. Our simulation results present a numerical view of this distributed scheme.
Transmission, reflection and localization in a random medium with absorption or gain

description: We study reflection and transmission of waves in a random tight-binding system with absorption or gain for weak disorder, using a scattering matrix formalism. Our aim is to discuss analytically the effects of absorption or gain on the statistics of wave transport. Treating the effects of absorption or gain exactly in the limit of no disorder, allows us to identify short- and long lengths regimes relative to absorption- or gain lengths, where the effects of absorption/gain on statistical properties are essentially different. In the long-lengths regime we find that a weak absorption or a weak gain induce identical statistical corrections in the inverse localization length, but lead to different corrections in the mean reflection coefficient. In contrast, a strong absorption or a strong gain strongly suppress the effect of disorder in identical ways (to leading order), both in the localization length and in the mean reflection coefficient.
