Att bygga hus på stolpar, upplyfta ovanför mark eller vatten, har varit ett traditionellt sätt att bygga i många delar av världen och även i Sverige finns exempel på detta. På senare tid har det lyfts fram som en metod för varsam grundläggning för att bevara naturen i områden med höga natur- och kulturvärden. Liknande grundläggning har även getts som förslag för att klimatanpassa byggnader. Eftersom det finns begränsat med studier om moderna hus på stolpar är det intressant att studera metoden. Det är också intressant eftersom det möjliggör små ingrepp i naturen och kan vara ett sätt att minimera klimatpåverkan från grundläggningen. Syftet med studien är att bidra till en ökad förståelse för hur stolpar som byggnadsmetod fungerar och hur metoden kan användas i Sverige. Målet är att identifiera kunskaper och erfarenheter om stolpmetoden från olika aktörer som medverkat i projektet Emils Backe, ett kuperat område med nybyggda villor på stolpar. Fem personer har intervjuats utifrån aktörsperspektiven arkitekt, konstruktör, byggentreprenör, bygglovhandläggare och projektets initiativtagare. En litteraturöversikt genomfördes för att urskilja redan kända kunskaper inom ämnet och för att skapa en grund för intervjustudien. Fokus under intervjuerna har varit att identifiera när stolphus kan vara en lämplig byggmetod, vad som måste beaktas och vilka potentiella fördelar och nackdelar som finns med att bygga på det sättet. Resultatet från intervjuerna och litteraturöversikten indikerar att den främsta fördelen med stolphus är att naturen och platsens karaktär kan bevaras, vilket handlar om att byggnaden kan anpassas till platsen och inte tvärtom. Detta tack vare att stolpmetoden inte medför lika omfattande mark- och grundläggningsarbeten som konventionella metoder. Resultatet visar även andra fördelar så som att den möjliggör ett lägre koldioxidavtryck och utnyttjandet av mer mark, skyddar mot rinnande vatten och annan fuktpåverkan underifrån samt förenklar vid underhåll. Att lyfta upp hus på stolpar kan även bidra till både högre och lägre boendekvaliteter. Bland nackdelarna visar resultatet att stolpmetoden är sämre ur energisynpunkt jämfört med konventionella grundläggningsmetoder eftersom bjälklaget blir en till yta som gränsar mot uteluft. Det kan även vara svårt med tillgängligheten till huset, svårt att hitta byggare och konstruktörer som kan räkna och bygga stolphus samt att detaljplaner kan försvåra byggandet av stolphus vid krav på låga byggnadshöjder. Resultatet pekar även mot att det är en enkel konstruktion men svårare och dyrare att bygga på grund många byggställningar, den sluttande marken och arbete på hög höjd. På svårbyggda tomter kan det dock vara både enklare och billigare att använda stolpar än att spränga och bereda marken för konventionell grundläggning. Viktiga aspekter att beakta är platsens förutsättningar, det arkitektoniska uttrycket och att se till att vatten och avlopp inte fryser. Även energiaspekten, stolphusets utformning för en lång livslängd och bra bärighet samt hur huset kan monteras ihop för en säker arbetsmiljö under byggtiden behöver beaktas. Sammanfattningsvis pekar resultatet mot att stolpar kan vara särskilt lämpliga att använda på kuperade, sluttande och andra svårbyggda tomter, i områden med risk för översvämning samt i områden med höga naturvärden. Förslag för framtida studier är att se över hur stolphus kan utformas som ett passivhus trots att det är kallt runt hela byggnadens klimatskal samt hur detaljplanerna kan utformas för att möjliggöra stolphusbyggande. / Building houses on stilts, elevated above ground or water, has been a traditional way of building in many parts of the world for centuries and even in Sweden there are examples of this. More recently, it has gained attention as a mindful method for creating a foundation whilst preserving nature in areas with high natural and cultural significance. Similar foundations have also been suggested for climate adaptation of buildings. Since there are limited studies of modern houses on stilts, it is interesting to study the method. It is also interesting as it allows small interventions in nature and can be a way to minimize the climate impact from foundation construction. The purpose of this master thesis is to contribute to an increased understanding of how this building method works and how the method can be used in Sweden. The goal is to identify knowledge and experience about the stilt method from various professionals who participated in the project Emils Backe, a hilly area with newly built villas on stilts. Five people have been interviewed to give the perspective of an architect, a structural engineer, a building contractor, a building permit manager and the founder of the project. A literature review was conducted to identify existing knowledge as a basis for the interview study. The focus during the interviews has been to identify when the use of stilts can be an appropriate construction method, what needs to be considered and what potential advantages and disadvantages there are in building in this way. Results of the interviews and the literature review indicate that the main advantage of stilt houses is that nature and the character of the site can be preserved, which means that the building can be adapted to the site instead of the other way around. This is because the stilt method does not entail as extensive ground and foundation work as conventional methods. Other advantages include: enabling a lower carbon footprint, utilizing of more land, protecting against running water and other moisture effects from below and simplifying maintenance. Raising houses on stilts can also contribute to higher accommodation quality, but the opposite may also occur. Among the disadvantages, the results show that the stilt method is inferior to conventional methods from an energy point of view since the floor of the house becomes yet another surface from which heat loss arises. It can also be difficult to create easy access to the house, and to find builders and structural engineers who can count and build houses on stilts. Local development plans can also make the construction of stilt houses difficult when claiming low building heights. Findings also indicate that it is a simple structure but difficult and more expensive to build due to many scaffoldings, sloping ground and high-altitude work. However, on difficult-to-build sites, using stilts can be both easier and cheaper than blasting and preparing the ground for conventional grounding. Important aspects to consider are the conditions of the site, the architectural expression and to ensure that water and sewers do not freeze. The energy aspect, the design of the stilts for a long service life and good bearing capacity, and how the house can be mounted to ensure a safe working environment during construction also needs to be taken into consideration. In summary, the results indicate that stilts may be particularly suitable for use on hilly, sloping and other difficult-to-build sites, in areas with a risk of flooding and in areas with high natural significance. Proposals for future studies are to consider how stilt houses can be designed as a passive house, even though it is cold around the entire building's climate shell, and how local plans can be designed to enable stilt houses to be built.

Indiana University-Purdue University Indianapolis (IUPUI) / The exportation of institutions from developed economies to developing countries has been a development strategy that international actors have employed for decades. In the 1990s and early 2000s international donors introduced philanthropic foundations into African countries. The Ford Foundation was instrumental in setting up a number of foundations in African countries to promote the mobilization of local philanthropic resources for self-reliant community-driven development. However, more than a decade after their establishment the Ford-founded philanthropic institutions continued to depend heavily on international funding. This dissertation investigates why Ford’s exportation of foundation philanthropy to African countries for the promotion of local resource mobilization was unsuccessful. Current explanations attribute the local resource mobilization ineffectiveness of donor-founded philanthropic institutions to domestic factors --- developing country governments’ failure to provide an enabling environment for the development of nonprofit institutions. Drawing on quantitative and qualitative data, I go beyond the endogenous explanations to examine the role and institutional transplantation strategies of the external actor, the Ford Foundation. Based on in-depth interviews with former staff and consultants of the Ford Foundation, as well as staff of selected Ford-founded African foundations in Kenya, Ghana, and Senegal (namely The Kenya Community Development Foundation, the African Women's Development Fund, and TrustAfrica) I contend that the oft-cited domestic “obstacles” are actually the preexisting local conditions that Ford should have taken into consideration during the formulation and implementation of its philanthropy promotion program in African countries. Using institutional transplantation theories as a framework, I argue that Ford failed to achieve its local resource mobilization goal in African countries because the American-inspired foundation model that it transplanted in those countries for the purpose was incompatible with the local African cultures of giving and philanthropy.

Vid konstruktion av utomhusställverk behöver laster beräknas för dimensionering av fundament, stativ och grundbultar. Dessa beräkningar är tidskrävande och kräver god kunskap i standarder för ställverk. Utvecklandet av ett Exceldokument som beräknar krafterna som verkar på fundament, stativet och grundbultar, samt en ställverksmall med tillhörande stålritningar underlättar och försnabbar arbetet.  Beroende på vilken nätspänning ställverket är konstruerat för, förändras säkerhetsavståndet mellan apparater och till marken. Därför behövs det olika mallar för olika spänningar. Apparaterna som används blir tyngre och större vid högre spänningar därför måste stålet dimensioneras därefter. Dessa mallar är gjorda i Solidworks och består av sammanställning med alla stativ och apparater, samt en fundamentplan som alla delar är parade med för att enkelt kunna ändra utformningen av ställverket.  Standarder för mekanisk dimensionering av ställverkskonstruktion har följts för att göra ett exceldokument som beräknar dimensionerande laster på ställverkets stativ och fundament.  Genom att ange mått från ställverksritningen och teknisk information från beställaren i Exceldokumentet så beräknas böjspänning och vridskjuvspänning i stativen, normal- och skjuvspänning i bultar och hålkantstryck på fotplåten.  Exceldokumentet förväntas spara ca 12 timmar vid beräkning av spänningar i stativ och fundament. För ställverksmallen är förhoppningen att spara ca 80 timmar.  På grund av tidsbrist slutfördes endast en utav de nio påtänkta mallarna. Exceldokumentet skulle kunna vidareutvecklas till att beräkna vindlast på stativen och kortslutningskrafter men med minimal tidsbesparing. / During the construction of outdoor substation, loads need to be calculated to design the foundations, frames, and anchor bolts. These calculations are time-consuming and require a good understanding of standards for substations. The development of an Excel document that calculates the forces acting on the foundations, frames, and anchor bolts, along with a substation template and associated steel drawings, facilitates and speeds up the work. Depending on the voltage for which the substation is designed, the safety clearance between the equipment and the ground changes. Therefore, different templates are needed for different voltages. The equipment used becomes heavier and larger at higher voltages, so the steel must be dimensioned accordingly. These templates are created in Solidworks and consist of an assembly of all frames and equipment, as well as a foundation plan where all parts are paired to easily modify the design of the substation. Standards for the mechanical design of substation structures have been followed to create an Excel document that calculates the design loads on the substation frames and foundations. By entering some measurements from the substation drawings and some technical information from the client into the Excel document, the bending stress and shear stress in the frames, normal and shear stress in the bolts, and edge pressure on the base plate are calculated. The Excel document is expected to save approximately 12 hours when calculating stresses in the frames and foundations. For the substation template, the hope is to save around 80 hours. Due to time constraints, only one out of the planned nine templates was completed. The Excel document could be further developed to calculate wind loads on the frames and short-circuit forces, but with minimal time savings. / <p>Betygsdatum 2023-06-07</p>

<p>This thesis empirically investigates two distinct themes in public economics: tax policy and the economics of the charitable sector. The first chapter of the thesis examines the first theme of tax policy and focuses on how a change in the income tax affects labour market behaviour in Russia. The second theme of the economics of the charitable sector is explored in the final two chapters of the thesis. These chapters analyze the role of Canadian foundations in the provision of charitable goods.</p> <p>The first chapter examines the effect of Russia's flat tax reform on two employment dimensions: primary vs. secondary and official vs. unofficial. The chapter shows that individuals respond to lower taxes by devoting less time to primary and secondary employment. Official and unofficial employment, however, remain unaffected by the flat tax reform.</p> <p>The next two chapters depart from tax policy and study the role of foundations in the Canadian charitable sector. The second chapter of the thesis provides new evidence on the size-based operation of foundations and their financial structure in Canada. A third of foundations operating in Canada are quite small, with assets of less than $25,000. The remaining foundations can be classified as medium (with assets more than $25,000 and never more than one million dollars in a given year) or large (with assets of one million dollars in at least one year). Over the last 20 years, there are only small differences in the growth and use of funding between public and private medium-size foundations. For the large-scale foundations, we observe distinct differences in the expenditures of private and public foundations. Private foundations distribute more of their expenditures to other charities whereas public foundations devote more of their expenditures to internal activities.</p> <p>The final chapter of the thesis explores the impact of foundation grants to charities on the private donations received by these charities. Theoretically, foundation grants have two competing effects on private donations: a negative crowd-out effect and a positive information effect. An overall positive effect prevails only if the positive effect of signaling information about charity quality outweighs the negative crowd-out effect. With data on Canadian social welfare and community charities matched to their specific foundation donors, this chapter empirically examines the overall effect and finds that an additional dollar of foundation grants to Canadian charities crowds-in private giving to these organizations on average by 3.70 dollars.</p> / Doctor of Philosophy (PhD)

L'objectif de ce travail est d'analyser l'influence du renforcement du sol par la method Soil Mixing sur le comportement des fondations superficielles et profondes. Une étude numérique a été effectuée – avec des analyses éléments finis dans ABAQUS - dans le but d'acquérir une compréhension du fonctionnement et une estimation de la performance des fondations améliorées. Pour être en mesure d'utiliser des colonnes SM pour l'amélioration de la fondation, il est nécessaire de bien comprendre leur performance sous charge axiale statique. Par conséquent, une série de simulations reproduisant des essais de chargement d'une seule colonne, et d’un groupe de colonnes ont été réalisées. Les essais à pleine et petite échelle ont été modélisés et leurs résultats comparés avec les observations expérimentales. Un bon accord entre les prédictions numériques et les mesures confirme une bonne calibration des lois constitutives des sols, des colonnes et de l’interface sol/colonne en SM. En outre, cette étude a révélé que la colonne SM agit d'une manière similaire à un pieu en béton, son comportement est régi principalement par l'interface. Ensuite, la modélisation numérique d’une fondation superficielle à petite échelle a été menée. Deux types de renforcement ont été étudiés. Le premier consiste en une seule colonne, située au centre sous la semelle analysée. Le second cas correspond à un groupe de quatre colonnes SM. Deux densités de sol ont été analysés. L'objectif de la modélisation est d'identifier l'efficacité du renforcement en termes de capacité portante de la fondation et de la réduction de son déplacement vertical. Il a été trouvé que la densité du sable a un impact significatif sur le comportement de la semelle. La variation de densité a entraîné une différence significative entre les forces totales portées par les fondations. Mais, il a été constaté que le pourcentage de la force reprise par le sol par rapport à la force total, est indépendant de la densité. L'influence du renforcement obtenu par un groupe de colonnes SM sur une fondation profonde, a été étudiée. La modélisation numérique d'un seul pieu théorique installé dans le sol homogène, a été réalisée. L'objectif de l'étude est de détecter l'impact de divers paramètres, tels que la distance horizontale entre les colonnes de SM, la distance verticale entre les têtes de colonnes et la pointe de pieu, le diamètre et la longueur des éléments SM, sur la capacité portante de la fondation. On a montré que la distance entre les colonnes et leur diamètre ont la plus grande influence sur la force de charge, la longueur de renforcement conduit à une moindre influence. / The aim of this work is to analyse the influence of soil reinforcement executed by the Soil Mixing method on the behaviour of shallow and deep foundations. Numerical investigation has been carried out - with the use of Finite Element (FE) analyses in ABAQUS - in an attempt to identify the mechanisms guiding the performance of supported foundations. To be able to use SM columns as the foundation’s improvement, it is necessary to fully understand their performance under applied static, axial load. Therefore, a set of simulations reproducing loading tests of single and group of columns have been carried out. Full and small scale tests have been modelled and their results compared with experimental observations. Good agreement between numerical predictions and measurements, confirms proper calibration of the chosen constitutive laws of: soils, columns and interactions between them. Moreover, this study has revealed that the SM column acts in a similar way to concrete pile, hence its behaviour is governed mainly by the interface. Afterwards, numerical modelling of small scale shallow foundation has been accomplished. Two kinds of reinforcement have been investigated. The first one consists of a single column situated centrally under the analysed footing. The second kind of improvement involves group of four SM columns. Two densities of soil have been analysed. The goal of the modelling is to identify the efficiency of the reinforcement in terms of: bearing capacity of the foundation and reduction of its vertical displacement. Despite significant difference between total forces borne by the foundation tested on soil with different densities, it has been found that the percentage of the total force that was taken by the soil is density independent. The influence of reinforcement executed by group of SM columns on a deep foundation has been studied. Numerical modelling of a theoretical, single pile, installed in homogeneous soil, has been carried out. The aim of the investigation is to detect the impact of parameters such as: pattern of reinforcing elements, horizontal distance between SM columns, vertical distance between columns’ heads and tip of the pile, diameter and length of SM elements, on the bearing capacity of the foundation. It has been found that the distance between columns and their diameter has the biggest influence on the borne force. However, the length of the reinforcement has shown the least significant influence.

Bridge failures in the past decade due to structural deficiencies demonstrated the clear need for a review of the current bridge analysis approaches. This study focuses on pile-supported bridges under predominantly static loading. A critical review of the current analysis approaches was performed. It was concluded that in the absence of an onerous iteration process, the current approaches often produce inaccurate and, in many cases, unsafe results since the interactions between superstructure and foundation are not fully considered. To address the inherent limitations of the current approaches, a computer program [Soil Spring Module (SSM) 2.0] was developed as a part of the study. SSM 2.0 can be used in conjunction with a frame analysis program to capture nonlinear load transfer from foundation elements to soil in different directions simultaneously. STAAD.Pro was selected for demonstration in this study. Using SSM 2.0 and STAAD.Pro, this study proposes a new analysis approach using the Integrated Analysis Process (IAP). The same methodology can be applied in other frame analysis programs. Kansas Bridge 45 was selected as a case study. Using the IAP approach, a series of integrated analyses including all superstructure elements (e.g., deck, girders and piers) and all foundation elements (e.g., pile caps and piles) were performed on Kansas Bridge 45 for different soil types and properties. Different from the conventional approaches, the full interactions between superstructure and foundation were considered simultaneously in a single analysis using the IAP approach. The analysis results from the IAP approach and the conventional approaches were examined. The advantages of the IAP approach were identified. Comparing to the conventional approaches in current practice, the proposed IAP approach does not involve crude assumptions or intensive iterations. Using the IAP approach, design engineers can complete structural and foundation analysis of pile-supported bridges with good accuracy in a timely manner. The same methodology can potentially be applied to other structure types. / Graduate / 2022-12-15

Few South African students pass Grade 12 Physical Science with symbols required by university science, engineering and health science faculties. A large number of students who sit for Grade 12 Physical Science and Mathematics exams pass with symbols that are well below those required by the mainstream science courses at South African universities. Most South African universities have introduced Science Foundation Programmes with the aim of upgrading those students who failed to obtain university entrance symbols in the relevant subjects. Amongst the courses offered in Science Foundation Programmes is Foundation Physics. This study investigates the influence of Foundation Physics in order to find out if the programmes in different institutions are successful in empowering the students who failed to get the required entrance mark in Grade 12 Physical Science. Four South African Historically Black universities participated in this study. The Force and Motion Conceptual Evaluation test (FMCE) (Thornton & Sokoloff, 1998) and mechanics marks were used to assess students' understanding of Newtonian mechanics. Data was analyzed from socio-cultural perspective. A total of 194 students participated in the study. Two groups of students were compared, i.e. those who did Foundation Physics (Foundation group) and those who did not do Foundation Physics (non-Foundation group). The students were tested after they had completed a mechanics module, which forms a great foundation of Physics I (Introductory Physics). Two focus group interviews were held with selected Foundation and non-Foundation students per institution. Students voiced their experiences in Physics I and Foundation Physics. Students were chosen to represent focus groups according to their performance in the FMCE test. Mechanics class performances were also used to evaluate students' performance. In order to establish how Foundation Physics is taught, Foundation Physics Lecturer interviews were conducted at all four institutions. Analysis of data showed that both Foundation and non-Foundation students performed equally in Physics I mechanics module. Foundation group performed better than the non-Foundation group in the FMCE, which is a conceptual test. Foundation Physics lecturers indicated that there were some differences in the way mechanics was taught in Physics I and Foundation Physics. These differences affected students' performance. The lecturers also indicated that there was minimal interaction between Physics I lecturers and Foundation Physics lecturers pertaining to the teaching of the two courses. What influence does Foundation Physics have on the performance of students in Physics I? This study found that students who did Foundation Physics performed better than those who did not do Foundation Physics in conceptual questions and both the groups perform equally in questions that require memorizing and calculations. This implies that Foundation Physics courses are empowering the students to perform well in Physics I. However, as it is evidenced by this research, the differences in assessment in Physics I and Foundation Physics courses in some institutions hampers Foundation Physics students' learning, because the questions asked require them to memorize without understanding, something they are not used to. The researcher recommends that Foundation Physics staff and Physics I staff should start communicating, not only about how Foundation Physics should be run as was the case in the past, but also on how best Physics I should be run. This might help in making sure that the two courses are assessed similarly at one institution. / Mathematics, Science and Technology Education / D. Phil.

A diminuição das perdas hídricas com a redução das pressões de operação das redes de distribuição é um fenômeno conhecido há muito tempo pelas companhias de saneamento e distribuição de água. Entre as técnicas empregadas para esta finalidade, a setorização apresenta-se, atualmente, como um dos instrumentos mais efetivos de melhoria e otimização dos serviços de abastecimento. A setorização consiste na separação do sistema de abastecimento hídrico urbano em distritos denominados zonas pitométricas, com o objetivo geral de estabelecer um controle mais efetivo das pressões e das vazões de água destas zonas. A ampla difusão desta técnica, no entanto, não seria possível sem a evolução tecnológica dos elementos chave, necessários à implementação deste método de controle de abastecimento hídrico urbano. Visando subsidiar o desenvolvimento de técnicas para problemas enfrentados na setorização de redes de abastecimento hídrico, neste trabalho é relatado um estudo de caso realizado nas dependências da Companhia de Saneamento Básico do Estado de São Paulo (SABESP) por meio do qual são apresentadas soluções implementadas por esta Companhia no decorrer de mais de cinco anos. Este tempo permitiu que os métodos apresentados atingissem o grau de maturação necessário para que fosse estabelecido um modelo de setorização funcional e cada vez mais confiável. Por meio deste estudo são apresentadas, como contribuição original, soluções orientadas à utilização de recursos do protocolo digital Foundation Fieldbus, visando agregar ainda mais autonomia e disponibilidade às instalações do sistema de abastecimento hídrico da superintendência do litoral da referida Companhia e incorporando a este sistema características diferenciais como interoperabilidade, flexibilidade e redundância dos elementos críticos que o compõem. / The decrease of the hydric losses with the reduction of the operation pressures of the distribution nets is a phenomenon a long time known for the sanitation and water distribution companies. Among the used techniques for this purpose, the division in sectors technique comes, now, as one of the more effective instruments of improvement and optimization of the supplying services. The division in sectors technique consists in the separation of the hydric urban provisioning system in districts denominated pitometric zones, with the general objective of establishing a more effective control of the water pressures and flows of these zones. The wide diffusion of this technique, however, would not be possible without the technological evolution of the key elements, necessary to carry out this control method of urban hydric supplying. Looking for subsidize the development of techniques for problems faced in the division in sectors technique of hydric provisioning nets, in this work is described a case study, accomplished in the dependences of the Company of Basic Sanitation of the State of São Paulo (SABESP) through which are presented solutions implemented by this Company which has been carried out for more than five years. This time allowed that the methods presented reach the necessary maturation degree so that a functional and each more reliable model of the division in sectors technique would be established. Through this study are presented, as original contribution, proposals guided to the use of resources of the digital protocol Foundation Fieldbus, looking for aggregate yet more autonomy and availability to the facilities of the hydric provisioning system of the coast superintendency of the referred Company and incorporating to this system differentiates characteristics as interoperability, flexibility and redundancy of the critical elements that composes it.

A tecnologia emergente dos dispositivos móveis como telefones celulares, handhelds e smartphones trouxe um novo paradigma para o uso desses equipamentos, que, além das convencionais chamadas de áudio, hoje suportam vídeo, internet e redes sem fio. Várias aplicações têm sido desenvolvidas para esse ambiente. Por outro lado, na área da automação industrial, os instrumentos de campo modernos contêm embutidos, internamente, conjuntos de informações que proporcionam grande oportunidade para a gestão de ativos. A necessidade do gerenciamento de ativos ocorre na fase de operação da planta industrial e é realizada por meio de ajustes finos, calibrações, alteração de configurações e manutenções, com o objetivo de se evitar paradas indesejadas. Esse trabalho insere-se no contexto de interface entre esses dois mundos: a computação móvel e o gerenciamento de ativos. Nesse sentido, é desenvolvida uma análise dos padrões abertos PROFIBUS PA, HART e Foundation Fieldbus e o uso das suas características aplicado ao gerenciamento de ativos. É apresentada, ainda, uma proposta e verificação de viabilidade técnica de uma arquitetura aplicada ao gerenciamento de ativos a partir de um dispositivo móvel usando-se um canal de comunicação seguro baseado no padrão CyberOPC para acesso à planta industrial / The emerging technology of mobile devices like cell phones, hand helds and smartphones has brought a new paradigm for the use of such equipment, witch, in addition to conventional audio calls, now supports video, internet and wireless networks. Several applications have been developed for this environment. On the other hand, in the industrial automation area, the modern field devices contain embedded information sets that provide great opportunity for asset management. The need for asset management occurs during the operation of the plant and is performed by means of fine tuning, calibration, changes of configuration and maintenance, in order to avoid undesired downtime. This work fits into the context of interface between these two worlds: mobile computing and asset management. In this sense, is made an analysis of open standards PROFIBUS PA, HART and Foundation Fieldbus and use its features applied to asset management. It also presented a proposal and verification of technical feasibility of an architecture applied to asset management from a mobile device using a secure communication channel based on the standard CyberOPC to access the industrial plant
