Abstract (sommario):

This paper presents an approach to correcting misclassified pixels in depth maps representing parts of the human body. A misclassified pixel is a pixel of a depth map which, incorrectly, has the ?background? value and does not accurately reflect the distance from the sensor to the body being scanned. A completely automatic, deep learning based solution for depth map correction is proposed. As an input, the solution requires a color image and a corresponding erroneous depth map. The input color image is segmented using deep neural network for human body segmentation. The extracted segments are further used as guidance to find and amend the misclassified pixels on the depth map using a simple average based filter. Unlike other depth map refinement solutions, this paper designs a method for the improvement of the input depth map in terms of completeness instead of precision. The proposed method does not exclude the application of other refinement methods. Instead, it can be used as the first step in a depth map enhancement pipeline to determine approximate depths for erroneous pixels, while other refinement methods can be applied in a second step to improve the accuracy of the recovered depths.

Abstract (sommario):

Except for hypothetical cases that are never encountered in practice, the solution for the parameters of analytic velocity versus depth functions is inherently nonunique. This nonuniqueness means that there is no particular parameter combination that represents “the” solution. The average discrepancy between the observed velocity‐depth (or time‐depth) curve and the calculated function curve gives a measure of the degree of fit between the two curves. In the parameter space, within a given degree of fit that may be considered as the margin of tolerance for the particular problem in hand, every parameter combination provides a valid solution. The solution trough is defined as the region in the parameter space containing these solutions. The shape of the solution trough depends on the relationship between the parameters and, therefore, on the form of the function being used. If the parameters are related linearly or if the relation is linearized then the axis of the solution trough is a straight line. The slope of the axis corresponds to a point close to the average depth of the interval to which the observed data pertain. The intercept corresponds to a velocity value that is quite close to the average velocity over the interval. These properties are extremely useful for understanding the nature of the solution trough in parameter space. Hence, composite displays of solution troughs pertaining to a number of wells can be interpreted to provide information on whether the unit to which the function corresponds has undergone any lateral changes. Such displays also illustrate how current practices that assume the existence of a unique or “true” solution need to be critically revised.

Abstract (sommario):

Abstract In the early morning of 13 February 1986, an earthquake with a duration magnitude (MD) of 3.2 rumbled through northwestern South Carolina. The event was centered near Lake Keowee in Oconee County in a region of prior low level seismicity. Approximately eighty aftershocks with magnitudes ranging from −1.0 to 2.0 were recorded during the next six days. The locations of five aftershocks were accurately determined, utilizing data from portable seismographs deployed in the epicentral area. Depths of the two earthquakes with a location quality of B or better were between 3 and 4 km. First motion focal mechanism solutions for the mainshock suggest oblique slip along a plane striking northeast or northwest. The P axis was oriented northeast-southwest in support of the directions obtained from mechanisms of other local earthquakes and from direct measurements of the maximum horizontal stress in the regions. A second mainshock (MD = 2.8) occurred in the vicinity of Lake Keowee on 11 June 1986 and was followed by over sixty earthquakes during the next five weeks. Focal mechanism solutions from first motion data obtained for the mainshock resemble those of the 13 February event and suggest oblique slip along a northeast or northwest striking plane. Depths of the best located aftershocks were approximately 1 km. Two tests were applied to the data to assess the reliability of the depth estimates. These involve the determination that the plot of RMS travel time residual versus fixed solution depth exhibits a single, sharp RMS minimum at the depth obtained from a free solution (depth uniqueness) and that the final free solution depth is not dependent upon the choice of starting depth (depth stability). Free solution depths obtained for the majority of the better located aftershocks were found to be unique and stable at depths between 1 and 4 km. A northeast trending anomaly is prominent in the geophysical data for this area. This anomaly is interpreted to result from an abrupt, lateral change in lithology along a shallow, northeast striking plane. The earthquakes do not appear to be associated with this feature. Instead, these earthquakes appear to be associated with a shallow body and may represent slip along northeast or northwest striking joints. The proximity of these earthquakes to Lake Keowee suggests the possibility of reservoir triggering. No correlation between seismicity and reservoir level is evident prior to the February events. Rapid fluctuations in water level did precede the events in June and July, providing possible triggering mechanisms.

Abstract (sommario):

AbstractThe bow flow generated by a wide flat-bottomed ship moving in water of finite depth is examined. Solutions obtained using an integral equation technique are presented for a range of different depths and for a range of angles of the front of the bow. The solution for the limiting case of infinite Froude number is obtained as an integral, and numerical solutions are found for the nonlinear problem in which the Froude number is finite. Solutions with smooth separation are shown to exist for all values of Froude number greater than unity, for any bow slope.

Abstract (sommario):

Abstract In his 1953 paper, Harald Sverdrup argued that the development of a spring bloom in the ocean depends on the juxtaposition of two depth horizons: the mixed-layer depth and the critical depth. Mixed-layer depth shallower than the critical depth favours phytoplankton growth in the layer and vice versa. However, mathematically, Sverdrup left the problem unsolved in the form of a transcendental equation. In spite of the high number of citations that this paper has garnered, the solution to this equation has not been found, until now. In this work, we present an analytical solution for the critical depth, as originally defined by Sverdrup. The paper opens with the definition of the critical depth and the description of the Lambert W function. The analytical solution for critical depth follows. Sverdrup’s original model is extended to include the effect of light attenuation by phytoplankton and the analytical solution for steady-state biomass in the mixed layer is derived. The expression for mixed-layer production at steady state is also presented. Two novel variants of the critical depth are defined: the optically uncoupled critical depth and the optically coupled critical depth. It is demonstrated that at steady state the optically coupled critical depth equals the mixed-layer depth and that the irradiance at the base of the mixed layer equals the irradiance at the optically uncoupled critical depth. Competitive exclusion is demonstrated to hold and the optically uncoupled critical depth is linked to the critical light intensity in multi-species competition. Finally, a conservation principle for the critical depth is found.

Abstract (sommario):

Critical depth is an essential parameter for the design, operation, and maintenance of conduits. Circular, arched, and egg-shaped sections are often used in non-pressure conduits in hydraulic engineering, irrigation, and sewerage works. However, equations governing the critical depth in various sections are complicated implicit transcendental equations. The function model is established for the geometric features of multiple sections using the mathematical transform method and while considering non-dimensional parameters. Then, revised PSO algorithms are implemented in MATLAB, and the right solution’s formula for the critical depths in various non-pressure conduit sections is established through optimization. The error analysis results show that the established formula has broad applicability. The maximum relative errors of the formula for critical depths are less than 0.182%, 0.0629%, and 0.170% in circular, arched, and egg-shaped sections, respectively, which are more accurate than those of existing formulas; the form of the formula proposed in this work is also more compact than that of the existing formulas. The results of this research may be useful in design, operation, and maintenance in conduit engineering.

Abstract (sommario):

The use of lasers has increased in areas of science, engineering and medicine. Their advantages over the traditional methods of thermal application are their ability to localize thermal treatments, ability to deliver high power density and to complete thermal processes in extremely short time periods. During the irradiation of a material, only a portion of the laser beam energy is absorbed. If the absorbed energy is high enough, melting can occur. The ability to predict, thus control the melting process is an advantage to manufacturing processes such as laser welding, surface re-melting and alloying. Using analytical approaches that are already in existence, this research adapts a mathematical model to approximate temperature profiles as well as isothermal depths given a single laser pulse. In order to assess the error associated with the adapted model, laser irradiation experiments are carried out on CP titanium samples using a focal spot of 600 μm and nitrogen gas as the shielding gas at a flow rate of 5 l/min. The effects of some important laser processing parameters on the melt depth are discussed. The adapted model approximated that the melt depth increases with both increasing laser power and increasing pulse duration. Furthermore, the experimental results revealed that it is the combination of short pulses and a high laser power that yields melt zones that are relatively free of porosity, craters and cracking. Additionally, an assessment of the error associated with the adapted model revealed that the adapted model generally overestimates the experimental data with increasing laser pulse duration. At a combination of 0.1s and 1200W (representing a combination of short laser pulse and high laser power) the error of approximation was 59%. The error increased to 90% at a combination of laser parameters 5s and 600W (representing a combination of a long laser pulse and low laser power). It is recommended that future studies be undertaken to improve modelling accuracies for a wider range of laser processing parameters.

Abstract (sommario):

A numerical solution algorithm based on finite volume method is developed for unsteady, two-dimensional, depth-averaged shallow water flow equations. The model is verified using test cases from the literature and free surface data obtained from measurements in a laboratory flume. Experiments are carried out in a horizontal, rectangular channel with vertical solid boxes attached on the sidewalls to obtain freesurface data set in flows where three-dimensionality is significant. Experimental data contain both subcritical and supercritical states. The shallow water equations are solved on a structured, rectangular grid system. Godunov type solution procedure evaluates the interface fluxes using an upwind method with an exact Riemann solver. The numerical solution reproduces analytical solutions for the test cases successfully. Comparison of the numerical results with the experimental two-dimensional free surface data is used to illustrate the limitations of the shallow water equations and improvements necessary for better simulation of such cases.

Abstract (sommario):

A geração de grande quantidade de vinhaça resultante da produção de etanol induziu questionamentos a respeito de sua disposição e possível armazenamento. No Estado de São Paulo, a norma P4.231 da CETESB restringiu a aplicação de vinhaça em muitos solos, resultando na necessidade de distribuí-la em áreas distantes da usina. Porém, devido a grande quantidade de água no resíduo, o transporte torna-se inviável do ponto de vista econômico. Uma alternativa para diminuir os custos de transporte é reduzir o volume por evaporação, originando a vinhaça concentrada (VC). No entanto, as temperaturas altas durante o processo de concentração provocam modificações na matéria orgânica, consequentemente, alterando a dinâmica das transformações do N no solo e, considerando ainda que a sua aplicação é realizada na linha de plantio, diferentemente da vinhaça não concentrada (VNC) que é aplicada em área total, pouco se conhece sobre os efeitos no solo e a sua eficiência agronômica. Com o objetivo de (1) conhecer algumas propriedades físico-químicas da VC e compará-la com a VNC, (2) avaliar os efeitos das doses de VC na fertilidade do solo, percolação de íons, produtividade de soqueira de cana-de-açúcar e qualidade tecnológica dos colmos e (3) determinar a mineralização líquida do N (Nm) foram: (I) coletadas amostras de VC e VNC em duas usinas entre os anos de 2010 e 2011, (II) realizado um experimento na cidade de Batatais, SP, em uma área comercial de cana-de-açúcar, (III) conduzido um experimento de incubação aeróbia com os objetivos de determinar o Nm e, através do ajuste a equação de primeira ordem, determinar a mineralização potencial do N (N0), a constante de mineralização do N (k) e (4) parametrizar o módulo SoilN do modelo APSIM para solo que recebeu aplicação de vinhaça. Verificou-se que o processo de concentração da vinhaça promove grande variação no teor de alguns elementos, especialmente o Na+ e as formas de nitrogênio amoniacal e nítrica. A aplicação de 30 m3 ha-1 de VC na linha da cana promoveu aumento nas concentrações de Cl-, NO3 -, Ca+2, Mg+2 e SO4 -2 nas soluções coletadas pelos extratores a 0,80 m de profundidade. De maneira geral foi observado aumento do pH, CTC e dos teores dos cátions trocáveis em função das doses, ao mesmo tempo que os valores de m% decresceram, resultando dessa forma em maior disponibilidade de nutrientes, aumento da fertilidade do solo e consequentemente aumento de produtividade, pois os tratamentos com VC promoveram ganhos de 8 Mg ha-1 em relação ao tratamento controle e, mesmo pela grande quantidade de K+ concentrado na linha de plantio as características tecnológicas dos colmos não foram prejudicadas. Com base nos valores de Nm, N0 e k, pode-se concluir que ocorreu imobilização do N mineral pela biomassa microbiana nos tratamentos com VC. O módulo SoilN do APSIM apresentou bom desempenho em simular a produção de NO3 -, pois a nitrificação calculada diariamente a partir do modelo se ajustou adequadamente aos valores de nitrato observados nas incubações; o modelo foi bem sucedido em calcular as perdas de N no tratamento com a maior dose de VNC a partir dos valores da curva de retenção e do volume de água aplicada no solo.
In São Paulo State, the legislation from CETESB restricts the application of vinasse in many soils, resulting in the need to distribute it in areas distant from the mill. However, due to the large amount of waste water, the transport becomes unfeasible economically. An alternative is to reduce the volume by evaporation, resulting in the concentrated vinasse (CV). But, high temperatures during the evaporation cause changes in the organic matter. So, considering that its application is in the row of sugarcane, unlike the not concentrated vinasse (NCV) which is applied in the total area, the objectives were (1) study some physicochemical properties of the CV and compare it with NCV, (2) evaluate the effects of CV in soil fertility, ions percolation, productivity, and technological quality of stems and (3) evaluate the net N mineralization (Nm). (I) Samples of CV and NCV were collected at two sugarcane mills in 2010 and 2011, (II) an experiment was conducted in São Paulo, in a commercial sugarcane area, (III) an aerobic incubation was conducted to determine Nm, potential N mineralization (N0), rate of N mineralization (k) and (IV) parameterize SoilN APSIM model for soil with vinasse application. It was found that the evaporation of the vinasse leads to greater variation in the concentration of some elements, especially Na+ and ammoniacal and nitrate nitrogen. 30 m3 ha-1 of CV applied in the sugarcane line caused high concentration of Cl-, NO3 -, Ca +2, Mg+2 and SO4 -2 in the soil solutions collected at 0.80 m. There were increase in pH, CEC and the content of the cations, while the values of m% decreased, resulting in availability of nutrient, increasing the soil fertility and productivity. CV promoted gains of 8 Mg ha-1 compared to control and, even the large amount of K+ concentrated in the sugarcane line, the technological characteristics of the stems were not impaired. Based on the values of Nm, k and N0, we can conclude that the mineral N was immobilized by microbial biomass in CV treatments. The APSIM showed good performance to simulate NO3 - production. The nitrification calculated daily from the model was successful to fit to the values observed. The model was successful to calculate N losses in treatment with the highest dose of NCV.

Abstract (sommario):

The behavior of many systems of practical interest in communications and other areas is well modeled by a single server exponential queueing system in which the arrival and service rates are dependent upon the state of a Markov chain, the dynamics of which are independent of the queue length. Formal solution to such models based on Neuts's matrix geometric approach have appeared frequently in the literature. A major problem in using the matrix geometric approach is the computation of the rate matrix, which requires the solution of a matrix polynomial. In particular, computational times appear to be unpredictable and excessive for many problems of practical interest. Alternative techniques which employ eigenanalysis have been developed. These techniques are polynomially bounded and yield results very quickly compared to iterative routines. On the other hand, the class of systems to which the eigenanalysis based techniques apply have been somewhat restricted. In this thesis, we modify the eigenanalysis approach initially presented in order to remove some of these restrictions.

Abstract (sommario):

In this thesis we have developed solutions to common issues regarding widefield microscopes, facing the problem of the intensity inhomogeneity of an image and dealing with two strong limitations: the impossibility of acquiring either high detailed images representative of whole samples or deep 3D objects. First, we cope with the problem of the non-uniform distribution of the light signal inside a single image, named vignetting. In particular we proposed, for both light and fluorescent microscopy, non-parametric multi-image based methods, where the vignetting function is estimated directly from the sample without requiring any prior information. After getting flat-field corrected images, we studied how to fix the problem related to the limitation of the field of view of the camera, so to be able to acquire large areas at high magnification. To this purpose, we developed mosaicing techniques capable to work on-line. Starting from a set of overlapping images manually acquired, we validated a fast registration approach to accurately stitch together the images. Finally, we worked to virtually extend the field of view of the camera in the third dimension, with the purpose of reconstructing a single image completely in focus, stemming from objects having a relevant depth or being displaced in different focus planes. After studying the existing approaches for extending the depth of focus of the microscope, we proposed a general method that does not require any prior information. In order to compare the outcome of existing methods, different standard metrics are commonly used in literature. However, no metric is available to compare different methods in real cases. First, we validated a metric able to rank the methods as the Universal Quality Index does, but without needing any reference ground truth. Second, we proved that the approach we developed performs better in both synthetic and real cases.
In questa tesi abbiamo sviluppato soluzioni a questioni comuni in materia di microscopia a campo largo. Abbiamo affrontato il problema della non omogeneità dell'intensità delle immagini acquisite e due forti limitazioni: l'impossibilità di acquisire immagini ad alto dettaglio rappresentative o dell'intero campione o di oggetti 3D con spessore non trascurabile. Per prima cosa abbiamo studiato le caratteristiche del problema denominato vignettatura, relativo alla distribuzione non uniforme del segnale di luce all'interno di ogni singola immagine. In particolare abbiamo proposto metodi dove la funzione di vignettatura è stimata utilizzando un insieme di immagini acquisite direttamente dal campione. In seguito, abbiamo studiato come risolvere il problema legato alla limitata dimensione del campo di vista della telecamera, al fine di essere in grado di acquisire una singola immagine ad alto ingrandimento rappresentativa dell'intera area del campione osservato. A questo scopo abbiamo sviluppato tecniche di mosaicatura in grado di operare on-line con l'acquisizione delle immagini. Partendo da una serie di immagini acquisite manualmente, abbiamo validato un approccio di registrazione in grado di creare velocemente un mosaico allineando accuratamente le singole immagini acquisite. Infine, abbiamo studiato come estendere virtualmente il campo di vista della telecamera lungo la terza dimensione, con lo scopo di poter ottenere singole immagini completamente a fuoco di oggetti 3D. Abbiamo proposto un metodo generale che non richiede alcuna informazione a priori. Per confrontare i risultati dei diversi metodi, in letteratura sono tipicamente usate diverse metriche comuni. Tuttavia nessuna metrica è in grado di confrontare diversi metodi usando immagini reali. In primo luogo abbiamo validato una metrica in grado di classificare i diversi metodi in accordo all'indice di qualità universale, ma senza bisogno di alcuna verità di riferimento. Poi abbiamo dimostrato che il metodo che abbiamo sviluppato risulta essere il migliore tra tutti quelli testati per estendere la profondità di fuoco.

Abstract (sommario):

AbstractAbrasive water jet machining (AWJM) is an interesting solution for the production of shallow pockets in metal sheets made of titanium alloys. Indeed, it produces low cutting forces and heat generation and prevents deformation of these parts after machining. In addition, it has the advantage of only using two raw materials: sand and water. It is possible to generate pocket edges with an imposed geometry using AWJM, but it is necessary to tilt the axis of the jet. The material removal mechanism is then a function of the inclination angle. The presented study propose an improved model for modelling the pocket profile in TiAl6V parts. The experimental results shows that the model is efficient as the precision is around 5%.

Abstract (sommario):

AbstractPlants acquire K+ ions from the soil solution, and this small and dynamic pool needs to be quickly replenished via desorption of surface-adsorbed K from clay minerals and organic matter, by release of interlayer K from micaceous clay minerals and micas, or structural K from feldspars. Because of these chemical interactions with soil solid phases, solution K+ concentration is kept low and its mobility is restricted. In response, plants have evolved efficient strategies of root foraging. Root traits related to root system architecture (root angle and branching), root length and growth, together with root hairs and mycorrhiza-related traits help to determine the capacity of plants to cope with the poor mobility of soil K. Rooting depth is also important, given the potentially significant contribution of subsoil K in many soils. Root-induced depletion of K+ shifts the exchange equilibria, enhancing desorption of K, as well as the release of nonexchangeable, interlayer K from minerals in the rhizosphere. Both these pools can be bioavailable if plant roots can take up significant amounts of K at low concentrations in the soil solution (in the micromolar range). In addition, roots can significantly acidify their environment or release large amounts of organic compounds (exudates). These two processes ultimately promote the dissolution of micas and feldspars in the rhizosphere, contributing to the mining strategy evolved by plants. There are thus several root or rhizosphere-related traits (morphological, physiological, or biochemical) that determine the acquisition of K by crop species and genotypes.

Abstract (sommario):

A Tension Leg Platform (TLP) solution is proposed for dry tree applications in ultra-deep water depths (∼8000 ft). Major challenges for a TLP associated with the ultra deep environment are addressed with an innovative air spring – mass vibration absorber (VAB) system introduced by SBM Atlantia. The tendon system for the TLP therefore is able to scale essentially linearly with the water depth, instead of quadratically for a conventional TLP. This paper details the integrated platform design issues, including the hull, tendon design and the coupled motion analysis approach. It also discusses the system weight and dimension scales for typical applications and the constructability in terms of their upper bound limits compared with existing platforms. A design example is presented for the offshore Brazil Santos Basin environment at 8000 ft water depth with consistent current and relatively large fatigue sea states.

Abstract (sommario):

This Coastal and Hydraulics Engineering Technical Note (CHETN) documents the development through verification and validation of three instability-suppressing mechanisms in FUNWAVE-TVD, a Boussinesq-type numerical wave model, when modeling deep-draft vessels with a low under-keel clearance (UKC). Many large commercial ports and channels (e.g., Houston Ship Channel, Galveston, US Army Corps of Engineers [USACE]) are traveled and affected by tens of thousands of commercial vessel passages per year. In a series of recent projects undertaken for the Galveston District (USACE), it was discovered that when deep-draft vessels are modeled using pressure-source mechanisms, they can suffer from model instabilities when low UKC is employed (e.g., vessel draft of 12 m¹ in a channel of 15 m or less of depth), rendering a simulation unstable and obsolete. As an increasingly large number of deep-draft vessels are put into service, this problem is becoming more severe. This presents an operational challenge when modeling large container-type vessels in busy shipping channels, as these often will come as close as 1 m to the bottom of the channel, or even touch the bottom. This behavior would subsequently exhibit a numerical discontinuity in a given model and could severely limit the sample size of modeled vessels. This CHETN outlines a robust approach to suppressing such instability without compromising the integrity of the far-field vessel wave/wake solution. The three methods developed in this study aim to suppress high-frequency spikes generated nearfield of a vessel. They are a shock-capturing method, a friction method, and a viscosity method, respectively. The tests show that the combined shock-capturing and friction method is the most effective method to suppress the local high-frequency noises, while not affecting the far-field solution. A strong test, in which the target draft is larger than the channel depth, shows that there are no high-frequency noises generated in the case of ship squat as long as the shock-capturing method is used.

Abstract (sommario):

Many people enjoy wildlife. Nationwide, Americans spend over $144 billion annually on fishing, hunting, and wildlife-watching activities. However, wildlife is not always welcome in or near homes, buildings, or other property and can cause significant damage or health and safety issues. Many people who experience a wildlife conflict prefer to resolve the issue without harming the offending animal. Of the many options available (i.e., habitat modification, exclusion, repellents) for addressing nuisance wildlife problems, translocation—capturing and moving—of the offending animal is often perceived to be effective. However, trapping and translocating wild animals is rarely legal nor is it considered a viable solution by wildlife professionals for resolving most nuisance wildlife problems. Reasons to avoid translocating nuisance wildlife include legal restrictions, disease concerns, liability issues associated with injuries or damage caused by a translocated animal, stress to the animal, homing behavior, and risk of death to the animal. Translocation is appropriate in some situations such as re-establishing endangered species, enhancing genetic diversity, and stocking species in formerly occupied habitats. The main focus of this publication, however, is to address nuisance wildlife issues that may be commonly encountered by homeowners and nuisance wildlife control professionals.

Abstract (sommario):

How can education in Aotearoa New Zealand respond to climate change? This report, part of our wider education and climate change project, outlines findings from 17 in-depth interviews with individuals with a range of viewpoints about climate change and the role of education. Five priority perspectives are covered: youth (aged 16–25); educators; Māori; Pacific New Zealanders; and people with an academic, education system, or policy perspective. Key findings are: Education offers an important opportunity for diverse children and young people to engage in positive, solutions-focused climate learning and action. Interviewees shared local examples of effective climate change educational practice, but said it was often down to individual teachers, students, and schools choosing to make it a focus. Most interviewees said that climate change needs to be a more visible priority across the education system. The perspectives and examples shared suggest there is scope for growth and development in the way that schools and the wider education system in Aotearoa New Zealand respond to climate change. Interviewees’ experiences suggest that localised innovation and change is possible, particularly when young people and communities are informed about the causes and consequences of climate change, and are engaged with what they can do to make a difference. However, effective responses to climate change are affected by wider systems, societal and political structures, norms, and mindsets. Interviewee recommendations for schools, kura, and other learning settings include: Supporting diverse children and young people to develop their ideas and visions for a sustainable future, and to identify actions they can take to realise that future. Involving children and young people in collective and local approaches, and community-wide responses to climate change. Scaffolding learners to ensure that they were building key knowledge, as well as developing ethical thinking, systems thinking, and critical thinking. Focusing on new career opportunities and pathways in an economic transition to a low-carbon, changed climate future. Getting children and young people engaged and excited about what they can do, rather than disengaged, depressed, or feeling like they have no control of their future.

Testo completo

Abstract (sommario):

Tracking progress towards the Sustainable Development Goals (SDGs) is critical to evaluate how far the water and sanitation sector is from achieving these targets, and to guarantee that the solutions and strategies implemented get everyone closer to them. But this is not a simple task. To truly assess collective progress towards achieving SDG 6 (and all other goals), it is fundamental to count on standardized measures that help track all types of access, their reliability, and their quality. Existing data tend to lack comparability across sources and locations because they rely on different definitions and categories. Samples are often not representative of all groups within the population. More developed areas are more likely to collect data, which results in the overrepresentation of groups that enjoy better services. Still in some areas and for some categories of information data is not available at all. In response to these challenges, the Inter-American Development Bank (IDB) partnered with the Latin American Public Opinion Project (LAPOP) to gather nationally representative and comparable data in 18 countries in the region. The goal of this effort was to provide an initial outlook of the current landscape of water and sanitation services in the region, using two batteries of questions in the LAPOP questionnaire for the 2018-2019 wave. The main message that arises is that the Latin American and the Caribbean region faces a wide range of challenges, that vary both across and within countries. Some areas face the primary challenge of closing access gaps, while others display higher deficiency in service quality, such as continuity. The gaps in quality of services, in particular, are not clearly perceived by users. In general, levels of satisfaction with the services received is quite high among the population, much higher than warranted by the objective measures of service quality. This raises important issues for accountability in the sector. If users are mostly satisfied with the current state of affairs, it is unlikely they will pressure governments and utilities to improve service delivery. A more in-depth analysis is required to understand the reasons behind these opinions and possible ways to raise awareness.

Roye, Thorsten. Unsettled Technology Areas in Deterministic Assembly Approaches for Industry 4.0. SAE International, agosto 2021. http://dx.doi.org/10.4271/epr2021018.

Testo completo

Abstract (sommario):

Increased production rates and cost reduction are affecting manufacturing in all sectors of the mobility industry. One enabling methodology that could achieve these goals in the burgeoning “Industry 4.0” environment is the deterministic assembly (DA) approach. The DA approach is defined as an optimized assembly process; it always forms the same final structure and has a strong link to design-for-assembly and design-for-automation methodologies. It also looks at the whole supply chain, enabling drastic savings at the original equipment manufacturer (OEM) level by reducing recurring costs and lead time. Within Industry 4.0, DA will be required mainly for the aerospace and the space industry, but serves as an interesting approach for other industries assembling large and/or complex components. In its entirety, the DA approach connects an entire supply chain—from part manufacturing at an elementary level to an OEM’s final assembly line level. Addressing the whole process of aircraft design and manufacturing is necessary to develop further collaboration models between OEMs and the supply chain, including addressing the most pressing technology challenges. Since all parts aggregate at the OEM level, the OEM—as an integrator of all these single parts—needs special end-to-end methodologies to drastically decrease cost and lead time. This holistic approach can be considered in part design as well (in the design-for-automation and design-for-assembly philosophy). This allows for quicker assembly at the OEM level, such as “part-to-part” or “hole-to-hole” approaches, versus traditional, classical assembly methods like manual measurement or measurement-assisted assembly. In addition, it can increase flexibility regarding rate changes in production (such as those due to pandemic- or climate-related environmental challenges). The standardization and harmonization of these areas would help all industries and designers to have a deterministic approach with an end-to-end concept. Simulations can easily compare possible production and assembly steps with different impacts on local and global tolerances. Global measurement feedback needs high-accuracy turnkey solutions, which are very costly and inflexible. The goal of standardization would be to use Industry 4.0 feedback and features, as well as to define several building blocks of the DA approach as a one-way assembly (also known as one-up assembly, or “OUA”), false one-way assembly, “Jig-as-Master,” etc., up to the hole-to-hole assembly approach. The evolution of these assembly principles and the link to simulation approaches are undefined and unsolved domains; they are discussed in this report. They must be discussed in greater depth with aims of (first) clarifying the scope of the industry-wide alignment needs and (second) prioritizing the issues requiring standardization. NOTE: SAE EDGE™ Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE™ Research Reports is to stimulate discussion and work in the hope of promoting and speeding resolution of identified issues. SAE EDGE™ Research Reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.
