Crimean-Congo hemorrhagic fever is a common disease between humans and animals that is transmitted to humans through infected ticks, contact with infected animals, and infected humans. In this paper, we present a boxed model for the transmission of Crimean-Congo fever virus. With the help of the fixed-point theory, our proposed system model is investigated in detail to prove its unique solution. Given that the Caputo fractional-order derivative preserves the system’s historical memory, we use this fractional derivative in our modeling. The equilibrium points of the proposed system and their stability conditions are determined. Using the Euler method for the Caputo fractional-order derivative, we calculate the approximate solutions of the fractional system, and then, we present a numerical simulation for the transmission of Crimean-Congo hemorrhagic fever.

This paper presented a 3D point sink model through using Dirac function. Then, 3D point sink solution in boxed reservoirs was obtained through using Laplace transform and Fourier transform methods. Based on the flux and pressure equivalent conditions in Laplace space, a semianalytical solution for multifractured horizontal wells was also proposed for the first time. The production rate distribution was discussed in detail for multifractured horizontal wells. The calculative results show the outermost fractures had higher production ratio due to larger drainage area and the inner fractures were lower due to the strong interface between fractures. Type curves were established to analyze the flow characteristics, which would be divided into six stages, for example, bilinear flow region, the first linear flow region, the first radial flow region, the second linear flow region, the second radial flow region, and the boundary dominated flow region, respectively. Finally, effects of some sensitive parameters on type curves were also analyzed in detail.

Full textAbstract:
In this paper, we briefly review the boxed molecular dynamics (BXD) method which allows analysis of thermodynamics and kinetics in complicated molecular systems. BXD is a multiscale technique, in which thermodynamics and long-time dynamics are recovered from a set of short-time simulations. In this paper, we review previous applications of BXD to peptide cyclization, solution phase organic reaction dynamics and desorption of ions from self-assembled monolayers (SAMs). We also report preliminary results of simulations of diamond etching mechanisms and protein unfolding in atomic force microscopy experiments. The latter demonstrate a correlation between the protein's structural motifs and its potential of mean force. Simulations of these processes by standard molecular dynamics (MD) is typically not possible, because the experimental time scales are very long. However, BXD yields well-converged and physically meaningful results. Compared with other methods of accelerated MD, our BXD approach is very simple; it is easy to implement, and it provides an integrated approach for simultaneously obtaining both thermodynamics and kinetics. It also provides a strategy for obtaining statistically meaningful dynamical results in regions of configuration space that standard MD approaches would visit only very rarely.

Full textAbstract:
Background Sediment scour at downstream of hydraulic structures is one of the main reasons threatening its stability. Several soil properties and initial input data have been studied to investigate its influence on scour hole geometry by both physical and numerical models. However, parameters of resistance affecting sedimentation and erosion phenomena have not been carried out in the literature. Besides, the auxiliary-like wing walls prevalently used in many real applications have been rarely addressed for their effect on morphological change. Results In this study, a 3D Computational Fluid Dynamics model is utilized to calibrate the hydraulic characteristics of steady flow going through the culvert by comparison with experimental data, showing good agreement between water depth, velocity, and pressure profiles at the bottom of the boxed culvert. The results show that a grid cell of 0.015 m gave minimum NRMSE and MAE values in test cases. Another approach is numerical testing sediment scour at a meander flume outlet with a variety of roughness/d50 ratio (cs) and diversion wall types. The findings include the following: cs = 2.5 indicates the close agreement between the numerical and analytical results of maximum scour depth after the culvert; the influence of four types of wing wall on the geometrical deformation including erosion at the concave bank and deposition at the convex bank of the meander flume outlet; and two short headwalls represent the best solution that accounts for small morphological changes. Conclusions The influence of the roughness parameter of soil material and headwall types on sediment scour at the meander exit channel of hydraulic structure can be estimated by the numerical model.

Statement of the problem. Based on the analysis of domestic and foreign scientific publications and guidelines, it is found that the known deformation models for the calculation of complex tensile reinforced concrete elements during torsional bending are quite conditional. Therefore the article considers the solution of the problem of designing a computational model of a reinforced concrete element during torsion with bending in the post-crack stage, which most fully accounts for the specifics of crack formation, deformation and destruction of such elements. The case is considered for when among all possible external influences the action of torques and bending moments has the greatest influence on the stress-strain. Results. Using the equations of statics and physical ratios of reinforced concrete, the calculated parameters are identified such as stresses in concrete of compressed zone, height of compressed concrete, stresses in clamps, deformations in concrete and reinforcement, curvature and torsion angle of reinforced concrete element. Conclusions. The obtained analytical dependences were tested by means of numerical calculation of the reinforced concrete strapping crossbar of the outer contour of a residential building of box section of high-strength concrete. The suggested deformation model can be employed in the design of a wide class of reinforced concrete structures working on torsional bending.

The relevance of this study is due to the fact that in conditions of a limited budget, companies face important questions: what system to choose to support their HR cycle; to stop at a boxed solution or to develop their own; how to correctly calculate the costs of implementation and support of the system. Misunderstandings between technology platform developers and consumers may be hidden in the terminology used. When a decision-maker is looking for a system for storing educational content, the choice may not be the most optimal option, but the option that is most popular or has the widest functionality. The article presents the key trends and directions, technologies and solutions that are in the focus of corporate training; identifies the key technological platforms of e-learning in the human capital management system. The empirical basis of the study was the materials of the international consulting companies EFMD, ELearning Inside, Technavio, Metaari. The practical significance of this study lies in revealing the issues that companies face when choosing or creating their training system. The introduction of e-learning technological platforms in the human capital management system will not be easy in any case, but already at the beginning of this path it is necessary to keep the end user in mind.

Full textAbstract:
Coalition games have been recently used for modeling a variety of security problems. From securing the wireless transmissions in decentralized networks to employing effective intrusion detection systems in large organizations, cooperation among interested parties has shown to bring significant benefits. Motivating parties to abide to a solution is, however, a key problem in bridging the gap between theoretical models and practical solutions. Benefits should be distributed among players (wireless nodes in a network, different divisions of an organization in security risk management, or organizations cooperating to fight spam), such that no group of players is motivated to break off and form a new coalition. This problem, referred to as core allocation, grows computationally very expensive with a large number of agents. In this paper, we present a novel approximate core allocation algorithm, called the bounding boxed core (BBC), for large cooperative security games in characteristic form that rely on superadditivity. The proposed algorithm is an anytime (an algorithm is called anytime if it can be interrupted at any time point during execution to return an answer whose value, at least in certain classes of stochastic processes, improves in expectation as a function of the computation time) algorithm based on iterative state space search for better solutions. Experimental results on a 25-player game, with roughly 34 million coalitions, show that BBC shrinks the 25-dimensional bounding-box to times its initial hypervolume.

Постановка задачи. На основе анализа отечественных и зарубежных научных публикаций и нормативных документов установлено, что известные деформационные модели для расчета сложнонапряженных железобетонных элементов при кручении с изгибом носят достаточно условный характер.

Full textAbstract:
L'étude par continuation des solutions périodiques et quasi-périodiques est appliquée à plusieurs modèles issus du violon. La continuation pour un modèle à un degré de liberté avec friction régularisée permet de montrer la préservation, par rapport à la friction de Coulomb, des bifurcations de cycle limite (une vitesse maximale et une force minimale permettant le mouvement de Helmholtz) et de propriétés globales de la branche de solution (croissance de l'amplitude avec la vitesse, décroissance de la fréquence avec la force normale). L'équilibrage harmonique est évalué sur la friction régularisée et a des propriétés de convergence intéressantes (erreur faible, monotone, à décroissance rapide). La continuation sur un modèle à deux modes donne accès aux solutions de registres supérieurs, dont la stabilité coïncide avec l'expérience. La valeur retenue pour l'inharmonicité peut modifier fortement le diagramme de bifurcation. Une nouvelle méthode de continuation des solutions quasi-périodiques est proposée. Elle associe l'EH étendu à deux pulsations avec la Méthode Asymptotique Numérique. Une attention particulière est portée à la rapidité des calculs, face à la croissance rapide de la taille des systèmes à inverser. Un modèle de friction prenant en compte la température au point de contact est reformulé à l'aide d'une dérivée fractionnaire. Nous proposons une méthode de continuation de solutions périodiques de systèmes contenant des dérivées ou intégrales fractionnaires. Nous établissons une condition suffisante pour que les cycles asymptotiques du cadre causal (Caputo) soient solutions du cadre que nous avons choisi<br>The continuation of periodic and quasi-periodic solutions is performed on several models derived from the violin. The continuation for a one degree-of-freedom model with a regularized friction shows, compared with Coulomb friction, the persistence of limit cycle bifurcations (a maximum bow speed and a minimum normal force allowing Helmholtz motion) and of global properties of the solution branch (increase of amplitude with respect to the bow speed, decrease of frequency with respect to the normal force). The Harmonic Balance Method is assessed on this regularized friction system and shows interesting convergence properties (the error is low, monotone and rapidly decreasing). For two modes the continuation shows higher register solutions with a plausible stability. A stronger inharmonicity can greatly modify the bifurcation diagram. A new method is proposed for the continuation of quasi-periodic solutions. It couples a two-pulsations HBM with the Asymptotic Numerical Method. We have taken great care to deal efficiently with large systems of unknowns. A model of friction that takes into account temperature of the contact zone is reformulated with a fractional derivative. We then propose a method of continuation of periodic solutions for differential systems that contain fractional operators. Their definition is usually restricted to causal solutions, which prevents the existence of periodic solutions. Having chosen a specific definition of fractional operators to avoid this issue we establish a sufficient condition on asymptotically attractive cycles in the causal framework to be solutions of our framework

Yes<br>The lack of separation between urgent and non-urgent medical goods
encourages sub-optimal vehicle fleet operations owing to the time critical
nature of urgent items. An unattended electronic locker bank, to which
individual urgent items can be delivered thereby separating urgent and
non-urgent supply, was proposed for the Great Ormond Street Hospital in
London, UK. This concept was quantified using ‘basic’ and ‘intuitive’ hill
climbing optimisation models; and qualitatively using staff interviews and
expert reviews. Results indicated that a locker bank with a fixed height (1.7 m)
and depth (0.8 m) required a length of 4 m (basic model) and 3.63 m (intuitive
model), to accommodate 100% of urgent consignments for a typical week.
Staff interviews indicated the wider benefits such as staff personal deliveries.

Chapter 7 illustrates the results obtained by applying the Schrödinger equation to a simple pedagogical quantum system, the particle in a one-dimensional box. The wave functions are seen to be sine waves; their wavelengths are evaluated and used to calculate the quantized energies via the de Broglie relation. An energy-level diagram of some of the energies is constructed; on it are illustrations of the corresponding wave functions and probability distributions. The wave functions are seen to be either symmetric or antisymmetric about the midpoint of the line representing the box, thereby providing a lead-in to the later exploration of certain symmetry properties of multi-electron atoms. It is next pointed out that the Schrödinger equation for this system is identical to Newton’s equation describing the vibrations of a stretched musical string. The different meaning of the two solutions is discussed, as is the concept and structure of linear superpositions of them.

AbstractThe chapter gives an account of both opportunities and challenges of human–machine collaboration in citizen science. In the age of big data, scientists are facing the overwhelming task of analysing massive amounts of data, and machine learning techniques are becoming a possible solution. Human and artificial intelligence can be recombined in citizen science in numerous ways. For example, citizen scientists can be involved in training machine learning algorithms in such a way that they perform certain tasks such as image recognition. To illustrate the possible applications in different areas, we discuss example projects of human–machine cooperation with regard to their underlying concepts of learning. The use of machine learning techniques creates lots of opportunities, such as reducing the time of classification and scaling expert decision-making to large data sets. However, algorithms often remain black boxes and data biases are not visible at first glance. Addressing the lack of transparency both in terms of machine action and in handling user-generated data, the chapter discusses how machine learning is actually compatible with the idea of active citizenship and what conditions need to be met in order to move forward – both in citizen science and beyond.

AbstractThe top-down solver (TD) is a local fixpoint algorithm for arbitrary equation systems. It considers the right-hand sides as black boxes and detects dependencies between unknowns on the fly—features that significantly increase both its usability and practical efficiency. At the same time, the recursive evaluation strategy of the TD, combined with the non-local destabilization mechanism, obfuscates the correctness of the computed solution. To strengthen the confidence in tools relying on the TD as their fixpoint engine, we provide a first machine-checked proof of the partial correctness of the TD. Our proof builds on the observation that the TD can be obtained from a considerably simpler recursive fixpoint algorithm, the plain TD, by applying an optimization that neither affects the termination behavior nor the computed result. Accordingly, we break down the proof into a partial correctness proof of the plain TD, which is only then extended to include the optimization. The backbone of our proof is a mutual induction following the solver’s computation trace. We establish sufficient invariants about the solver state to conclude the correctness of its optimization, i.e., the plain TD terminates if and only if the TD terminates, and they return the identical result. The proof is written using Isabelle/HOL and is available in the archive of formal proofs.

Full textAbstract:
I started out hating the title of this volume. Disruption has a spe-cial place in the mythology of my native land of Silicon Valley: Every startup promises disruptive technologies that will change the industry forever, and “Don’t think outside the box—blow up all the boxes!” is written in invisible ink on the business card of every VC on Sand Hill Road. “Why do we want to disrupt the digital humanities?” I muttered to myself. Why would we want to borrow the rhetoric and methodology of Kleiner Perkins (which was known as a hegemonic boys club long before Ellen Pao sued them)? Is the Harvard MBA Program really the place to turn for new models of innovation in humanistic inquiry? Can’t we effect change—deep, meaningful change—without adopt-ing the language of one of the most inequitable neighborhoods of late-stage capitalism? But in the course of trying to find a place for my thoughts about community, conversation, and the digital humanities under an umbrella that is labeled disrupt, I have found my way to a new understanding of what we are doing here. What follows is an anatomy, a taxonomy, even a ge-nealogy of the term “disrupt” and a discussion of the questions that precipitate out of each usage of the word. The emphasis on questions rather than answers is intentional and, I think, important, for if we are to diversify the digital humanities, there must be room for multiple solutions to every problem.

Full textAbstract:
Black boxes are placeholders. What is a placeholder? What role do they play in science? These questions are addressed via a discussion of biological fitness. Fitness is the propensity of an organism or a trait to survive and reproduce. In addition, fitness is a placeholder for a deeper account that dispenses with the concept of fitness altogether. These two theses are in tension. Qua placeholder, fitness is explanatory. Qua disposition, it explicates but cannot explain the associated behavior. The solution involves drawing a distinction between two kinds of placeholders. First, a placeholder may stand in for the range of events to be accounted for. In this case, the placeholder functions as a frame. It spells out a range of behaviors in need of explanation. Second, a placeholder may stand in for mechanisms which bring about the behavior specified by the frame. When this occurs, the placeholder becomes an explanans and one can refer to it as a difference-maker.

Full textAbstract:
This paper discusses geotechnical aspects of the design and construction of a large bored pile cantilever retaining wall in Hamilton, New Zealand. Intrusive geotechnical investigations at the site identified sensitive weathered volcanic soils at founding level and raised concerns of strain-softening in the soil during earthquake shaking. The strain softening was considered likely to lead to unacceptable deformation of the wall and damage to surrounding properties. As well as traditional techniques, the investigation included cyclic triaxial testing and seismic dilatometer testing (sDMT) of the sensitive soils. Information from other sites in similar materials was gathered and used in the assessment. Of possible solutions, deep soil/cement-grout mixing of material in the passive zone of the retaining wall was assessed to be the most appropriate solution to limit softening and deformation. Observations from construction are made, and challenges faced due to the ground conditions are discussed.

When COVID-19 spread from China, the majority of people witnessed that the form of education changed. This situation has increased the need for online education platforms. Although videoconference platforms such as Zoom and Google Meet became popular to meet the requirement, these platforms have some drawbacks. To illustrate, the majority of students are not active and cannot take a proactive role during the lectures. Furthermore, they stay idle and get bored on the waiting rooms of these platforms. To fill this gap, an extendable functioning waiting room was created by using ASP.NET framework via Visual Studio platform. Proposed waiting room present a solution for enhancing user experience (UX) by increasing user engagement on the online education platform. This chapter would be interesting for not only educators who use online learning platforms but also videoconference platform users and developers.

Full textAbstract:
Efficient secondary use of real-world data (RWD) is a cornerstone for advancing data-driven medical research and personalised healthcare. However, significant challenges persist, including data fragmentation in silos, the lack of record linkage, and legal constraints that often hinder data utilisation. Especially Electronic Health Records (EHRs) represent a valuable data source, yet their potential remains largely untapped due to these barriers. Especially modern data space solutions promise to address these challenges, focusing on standardisation and harmonisation efforts, data governance aspects, as well as federated data-sharing approaches. A significant push in this area represents the European Health Data Space (EHDS) Act, focusing on an opt-out based approach for secondary use of health data. An additional consent-based approach (opt-in) represents data donation, which empowers individuals to contribute their data to research while maintaining trust and privacy under the current legal situation. The flagship project Smart FOX lays the foundations for making citizen-based data donations of EHR-standardised information usable in clinical research in Austria. As part of the architecture of the Austrian Health Data Donation Space (AHDDS), data donation boxes - Federated Open data eXchange Boxes (FOX BOXes) - present the fundamental decentralised building blocks for sharing EHR-standardised data. This paper outlines the architecture, functionality, and governance of FOX BOXes, highlighting its role in overcoming key barriers to health data sharing and its potential to accelerate data-driven research.

The present study found that library users found CUB E-journal One Search as a useful tool to get their desired information out of 9000 subscribed e-resources in the university. Most of the users used CUB E-journal One Search frequently in order to find relevant articles, write their assignments and research articles. The study indicated that the library users were influenced by Google like single search boxes and wished to have same features. Further, users expected features like document recommendation, search filters, RSS and on-screen help from the discovery tool. The paper is a first attempt to study the impact of open source discovery tools on the library users. It will further give confidence to the librarians in developing countries to deploy open source search solutions using Google Custom Search in the libraries.

Full textAbstract:
Abstract Two of the important corrosion problems encountered in coastal area bridges in the state of Louisiana, the pitting and packing corrosion, are analyzed. The pack rust obtained from an old carbon steel bridge structure analyzes mostly as magnetite, Fe3O4, with some α-FeOOH being present in some areas. Progression of pack rusting in already corroded and packed areas can be slowed down and prevented by the application of chemical conversion-type inhibitor solutions. Suitable methods are suggested. Pitting in weathering steel structures is more numerous in horizontal boxed-locations, where excessive amounts of rust debris and condensates collect and lead to sheet-type rusting. These can also be prevented by periodic cleaning and application of conversion coating-type chemicals.

Full textAbstract:
Abstract Components of potable water treatment plants (WTP) are susceptible to corrosion due to constant immersion in water and proximity to chlorine environments. A case history of corrosion problems at an Army WTP located in atmospherically corrosive environment with a combination of heat and high humidity, will be presented. Some of the solutions for the corrosion problems included: (1) advanced National Sanitary Foundation (NSF) approved coal tar epoxy for trough and surface wash components in filter tanks and flocculation tanks and (2) high micro-silica restoration mortar for deteriorated concrete. Also, valve pits at the WTP were coated with a high solids coal tar epoxy. Corroded electrical control boxes were cleaned and polished, then recoated with urethane. Corroded rubber gaskets in the boxes were replaced with corrosion chemical resistant nitrile foam gaskets. These materials and coatings have resulted in restoration of the plant to its optimum operating condition, in addition to reduced maintenance, and increased safety, increased operational readiness and reliability.

Full textAbstract:
Abstract An iGOSP initiative ties multiple solutions together on a common wireless infrastructure, which allows systems to interact in such a way that they create new features, capabilities, automation and monitoring. The result is a facility that has unique efficiencies, maximum return on asset and delivers unparalleled value, visibility, predictability and adaptability. NGPD selected Abqaiq GOSP-3 to pilot the concept of an intelligent GOSP (iGOSP). Abqaiq GOSP-3 is one of the oldest facilities in NGPD; which was commissioned in 1978. The plant’s rack room has gone through several upgrade projects in the past. This resulted in present challenges including: —Limited space in the rack room for any wired new instrument loop. Hence, an upgrade of the rack room will be needed for any future project.—Limited spare cables in field junction boxes.—Presence of local/pneumatic controllers. The ultimate goal is to sustain and expand Abqaiq GOSP 3 monitoring capabilities towards achieving operational excellence through the use of 4th Industrial Revolution (4IR) technologies. This plant is the first step in building a roadmap for other facilities to transform into the digital era through the use of state-of-the-art industrial wireless sensors technologies, such as digital twin, advanced data analytics, and augmented reality.

Full textAbstract:
Abstract The thermal Enhanced Oil Recovery (EOR) steam generation project in Petroleum Development Oman (PDO) is considered to be the first project in the Gulf region. This is a large-scale project that affects an entire country’s economic position. EOR through Heat recovery steam generation (HRSG) has been applied since 2012 in order to inject 11,000 to 13,000 steam-ton/day to produce around 135,000bbl net oil. This type of boilers consists of complex coil tubes varying from 2” to 4” inch diameters, and length &gt;11 km within 25m2 boxes. Repetitive failures were reported over the past 3-years due to the absence of appropriate inspection techniques to be used for detecting corrosion. Hence, decision was taken to fully replace these 4-units at a cost of approved US$ 100Mln with accumulated oil deferment. An “out of the box solution” was developed to inspect the tube coils to detect corrosion and to replace only the defect tube, accordingly. The free Swimming inspection tool pig (FSIT), which was qualified for inspecting non-piggable pipelines, has been re-engineered to meet the coil tubes size diameters and configuration, and to successfully conduct reliable inspection. The obtained data has confirmed the assurance and integrity of boiler tubes, and only minor defect were found to be replaced. This new technique has resulted in a tangible savings of compete set for the 4-HRSG units. Therefore, this has now been proven to be the HRSG standard tubes coil inspection tool for first time in the industry. This paper is an accumulation of a portion of significant exercises learnt from boilers issues that related the full affirmation and respectability to assess and gauge defects of complex boilers tubes.

<title>ABSTRACT</title> <p>For this particular effort, TARDEC Center for Systems Integration (CSI) was tasked to lead an effort to develop an underbody kit that would serve multiple functions. The underbody kit would provide an additional 1,200 lbs of net buoyancy to enhance water mobility per the LAV. This program is in the development and testing phase with a prototype expected to be produced June of 2015. This program is one of multiple efforts to ensure the FOLAV meet all system requirements to keep the vehicle viable to 2035. In addition, the TARDEC concept/prototype must meet the same mine blast protection provided by the underbody D-Kit that was produced for the fleet of vehicles in 2010. This is a unique challenge as a combination of buoyancy, mine blast, and structural requirement on a ground military vehicle is novel idea. Vehicle weight and survivability requirements are difficult challenges on combat vehicles, to include the LAV, so the TARDEC solution would have to reduce the weight of the shell by approximately 60% and still achieve current survivability. Typically 20-30% reductions are considered aggressive, but 60% is usually unattainable. <boxed-text> <p>Reference herein to any specific commercial company, product, process, or service by trade name, trademark, manufacturer, or otherwise does not necessarily constitute or imply its endorsement, recommendation, or favoring by the United States Government or the Dept. of the Army (DoA).

Full textAbstract:
The paper studies the direction of modeling and visualization of procedural objects in virtual environment systems, using hardware-accelerated ray tracing. In particular, the task of modeling objects defined by point clouds is considered, exemplified on landscape elements with negative slopes (caves, tunnels, cliffs, etc.). An approach to solve this task on the ray tracing pipeline is proposed, based on constructing bounding boxes, inside which cloud points retain proximity to each other. The paper describes methods and algorithms of forming such local point groups and bounding boxes, basing on a sparse voxel octree. Based on methods and algorithms proposed, a software complex was implemented and tested on a number of point clouds. The approbation showed that developed solution allows landscape features containing tens of millions of points to be modelled in real-time without consuming the power of unified GPU cores. The solutions obtained can be applied in virtual environment systems, scientific visualization, video simulators, geoinformation systems, etc.

Full textAbstract:
In popular media, recycled shipping containers are perennially touted as low-cost solutions for providing sustainable, high-performance homes1-4. However, there is limited analysis of the actual performance of shipping container buildings with respect to energy efficiency and overall carbon impact5. This project aims to fill that gap through a comparative analysis between a small shipping container home and a similarly sized home built with conventional high-performance assemblies.

Full textAbstract:
Limiting global warming to 1.5°C requires a large-scale removal of carbon dioxide from the atmosphere. The oceans have been proposed as one possible storage option, however, not without environmental consequences. Adverse impacts on ecosystems are expected to increase in the amount of carbon stored. The question arises whether the removed carbon should be stored in a small area, e.g. a bay, or spread out across the oceans. We study this question in an analytic model with two types of ocean boxes, characterised by their carbon content. Storing a lot of carbon in the small box (a bay) may cause the local ecosystem to cross a tipping point, whereas spreading out in the large box (the rest of the ocean) may avoid this, while still causing ecosystem damages. The model gives rise to two different steady state solutions. A “destroy” steady state, where the tipping point in the small ocean box has been crossed, and a “diffuse” steady state without destruction. We analytically and numerically study the optimal amount of carbon stored, and the optimal distribution of carbon sequestration across the two boxes.

Full textAbstract:
Funda Wande has adopted a ‘learning by doing’ strategy that is similar to the Problem Driven Iterative Adaptation (PDIA) approach to solving complex problems. PDIA is a high-impact process of innovation that helps organisations develop the capability to solve complex problems while they are solving such problems. It is a step-by-step framework that helps break down problems into their root causes, identify entry points, search for possible solutions, take action, reflect upon what is learned, adapt, and then act again. Its dynamic process and tight feedback loops enable teams to find and fit solutions to the local context. This case provides a narrative of the Funda Wande story with boxes illustrating how PDIA principles and tools like problem construction, deconstruction, entry point analysis, iteration, and building authorisation would have been applied in practice. The sources of this case include a literature review of education in South Africa, related research documents, and conversations with staff at Funda Wande.

McNaught, Tim. A Problem-Driven Approach to Education Reform: The Story of Sobral in Brazil. Research on Improving Systems of Education (RISE), 2022. http://dx.doi.org/10.35489/bsg-rise-ri_2022/039.
Full textAbstract:
For more than two decades, the Brazilian municipality of Sobral has focused intensively on improving the quality of its public education system; the resulting success has been remarkable. In 2005, the Brazilian federal government started calculating a Basic Education Development Index (IDEB in Portuguese), which measures the quality of education in schools across the country. In the inaugural results in 2005, 1,365 municipalities had a better score for primary education than Sobral. By 2017, Sobral made national news by ranking number one in the entire country for both primary and lower secondary education (Cruz and Loureiro, 2020). These results are even more impressive when considering that Sobral is located in the northeastern state of Ceará, which is the fifth poorest state in Brazil in terms of GDP per capita (Cruz and Loureiro, 2020). The case of Sobral exhibits many elements that are similar to Problem Driven Iterative Adaptation (PDIA), an approach wherein problems are key to driving change (Andrews et al., 2015). The PDIA approach relies on reformers to identify problems that matter, break them down into their root causes, identify entry points, act, stop to reflect, and then iterate and adapt their way to a solution.1 This process of constant feedback and experimentation by local actors allows for the development of a solution that fits the local context. This paper explores the transformation of Sobral’s education system through the lens of PDIA2 , with an emphasis on the early reform period of 2000-2004. Many excellent papers have been written, in Portuguese and English, about the case of Sobral; this paper draws heavily on this existing literature.3 The paper is also supported by interviews from key individuals who either were closely involved with the reform efforts or have studied them. The paper follows the narrative of the Sobral story, starting in 1997, and uses boxes and other diagrams to view the reform efforts through the lens of PDIA. Finally, the paper explains how the reform efforts grew and scaled over the years, not only within Sobral, but also to other municipalities in Ceará and across Brazil.

Full textAbstract:
This guide represents the state of the art of support fluid practice and aims to improve existing design, testing and practices for deep foundation elements – bored piles (drilled shafts), barrettes (LBEs) and diaphragm wall panels. It represents the first time that knowledge of good practice from around the world has been brought together into a single authoritative publication. The purpose of this Guide is to present current understanding on bentonite, other clays, polymers and blended systems, including the advantages and limitations, in order to allow informed selection of the optimum technical solution(s) for the conditions on each individual worksite. This Guide does not recommend any particular type of support fluid as each worksite has specific characteristics and requirements.This Guide will assist individuals and corporations involved in the procurement, design, and construction of deep foundations including Owners/Clients, Designers, General Contractors, Academics and Specialist Contractors. It is intended as a practical addition to existing standards, not a substitute. Project Specifications, Standards and Codes should always take precedence. This first edition details accepted industry good practice and will be followed by a second edition based on a comprehensive R&D program which will carry out a series of field research studies. The studies will collect data from active project sites and develop and conduct non-standard tests in order to establish what testing methods have substantial value and to better understand the validity of the compliance values in use. The task group will then produce a second edition of the guide that promises to be the best authority on the use of support fluids in the industry. This is expected to be published in 2021.

Klammler, Harald. Introduction to the Mechanics of Flow and Transport for Groundwater Scientists. The Groundwater Project, 2023. http://dx.doi.org/10.21083/gxat7083.
Full textAbstract:
Starting from Newton’s laws of motion and viscosity, this book is an introduction to fundamental aspects of fluid dynamics that are most relevant to groundwater scientists. Based on a perspective of driving versus resisting forces that govern the motion of a fluid, the author derives Darcy’s law for flow through porous media by drawing an analogy to Bernoulli’s law for fluid with negligible viscosity. By combining the effects of gravity and pressure, the author identifies hydraulic head as a convenient numerical quantity to represent the force driving groundwater flow. In contrast to the physical derivation of hydraulic head, hydraulic conductivity emerges as a parameter related to the resisting frictional forces between the mobile fluid and the stationary porous medium. These frictional seepage forces also affect the effective stress state of the porous medium, thus establishing a link to soil stability and quicksand formation. Combining Darcy’s law with the law of mass conservation leads the reader to the fundamental equations of saturated groundwater flow. Finally, the effects of capillary forces are included to establish the governing equations for unsaturated and multi-phase flow. Throughout the book, the author focuses on thoroughly illustrating and deriving the equations while applying order of magnitude analyses. This approach makes it possible to extract the most information, for example in terms of the scale of response time, without requiring explicit solutions. A number of boxes and solved exercises contain further details and links to practical applications such as the water table ratio that reflects ‘fullness’ of an aquifer and the performance of slug tests for in situ measurement of hydraulic conductivity. This book makes an important contribution to groundwater science by providing a progressive introductory explanation of the physical mechanics of groundwater flow and the accompanying socioeconomic and ecological problems that may arise.
