The research contributes to the uncertainty management of engineering systems by proposing and demonstrating a way to implement flexible platform strategy to respond to future uncertainties. In today's competitive market, where market segments are becoming more fragmented, pressure to develop and market diverse sets of products is increasing. To meet such market needs and reduce production cost at the same time, product platform strategy has been implemented in several different industries. Using a core set of common platform elements and variant-specific unique elements, a family of products can be produced to satisfy various market segments. However, the growing cost of platform development and undesired side effects of the strategy (e.g. performance tradeoff, cannibalization) is forcing companies to design their platforms with flexibility, so they can accommodate product variants, differentiate these variants, and be economically flexible to respond to specified future uncertainties. This thesis introduces a design process to architect flexible product platforms. The proposed process is demonstrated in two automotive application case studies.
(cont.) In the first case study, a vehicle floor pan is designed to satisfy two different length requirements, while being economically robust to future specification change and component demand. The second case study investigates a vehicle platform, where the flexible body in white (BIW) platform is designed for a family of three vehicle variants through identification of critical elements subset. Results showed that the flexible BIW platform is less profitable than the inflexible BIW platform, but when the degree of future uncertainty increases, the flexible design eventually becomes more profitable. This research provides additional examples that yet again confirms the general proposition "flexibility gains value as the degree of uncertainty increases."

In the last decade, there has been a surge in online platforms for providing a wide variety of services. These platforms face an array of challenges that can be mitigated with appropriate modeling and the use of optimization tools. In this thesis, we examine, model, and provide solutions to some of the key challenges. First, we focus on the problem of intelligent SMS routing faced by several online platforms today. In a dynamically changing environment, platforms need to carefully choose SMS aggregators to have a high number of text messages being delivered to users at a low cost. To model this problem, we consider a novel variant of the multi-armed bandit (MAB) problem, MAB with cost subsidy, which models many real-life applications where the learning agent has to pay to select an arm and is concerned about optimizing cumulative costs and rewards.
We show that naive generalizations of existing MAB algorithms like Upper Confidence Bound and Thompson Sampling do not perform well for the SMS routing problem. For an instance with K arms and time horizon T, we then establish a fundamental lower bound of [omega](K¹/³T²/³) on the performance of any online learning algorithm for this problem, highlighting the hardness of our problem in comparison to the classical MAB problem. We also present a simple variant of explore-then-commit and establish near-optimal regret bounds for this algorithm. Lastly, we perform numerical simulations to understand the behavior of a suite of algorithms for various instances and recommend a practical guide to employ different algorithms. Second, we focus on the problem of making real-time personalized recommendations which are now needed in just about every online setting, ranging from media platforms to e-commerce to social networks.
While the challenge of estimating user preferences has garnered significant attention, the operational problem of using such preferences to construct personalized offer sets to users is still a challenge, particularly in modern settings with a massive number of items and a millisecond response time requirement. Thus motivated, we propose an algorithm for personalized offer set optimization that runs in time sub-linear in the number of items while enjoying a uniform performance guarantee. Our algorithm works for an extremely general class of problems and models of user choice that includes the mixed multinomial logit model as a special case. Our algorithm can be entirely data-driven and empirical evaluation on a massive content discovery dataset shows that our implementation indeed runs fast and with increased performance relative to existing fast heuristics.
Third, we study the problem of modeling purchase of multiple items (in online and offline settings) and utilizing it to display optimized recommendations, which can lead to significantly higher revenues as compared to capturing purchase of only a single product in each transaction. We present a parsimonious multi-purchase family of choice models called the BundleMVL-K family, and develop a binary search based iterative strategy that efficiently computes optimized recommendations for this model. We establish the hardness of computing optimal recommendation sets and characterize structural properties of the optimal solution. The efficacy of our modeling and optimization techniques compared to competing solutions is shown using several real-world datasets on multiple metrics such as model fit, expected revenue gains, and run-time reductions. Fourth, we study the problem of A-B testing for online platforms.
Unlike traditional offline A-B testing, online platforms face some unique challenges such as sequential allocation of users into treatment groups, large number of user covariates to balance, and limited number of users available for each experiment, making randomization inefficient. We consider the problem of optimally allocating test subjects to either treatment with a view to maximize the precision of our estimate of the treatment effect. Our main contribution is a tractable algorithm for this problem in the online setting, where subjects must be assigned as they arrive, with covariates drawn from an elliptical distribution with finite second moment. We further characterize the gain in precision afforded by optimized allocations relative to randomized allocations and show that this gain grows large as the number of covariates grows.

Full textLa publicitat en línia té un paper important a Internet que permet finançar habitualment l'operació de llocs web que ofereixen contingut lliure als usuaris. A més, la personalització dels anuncis ha tornat la publicitat en línia un servei valuós per als usuaris. Si aconseguirem que hi hagi molts compradors siguin més que possibles, es promourà un negoci milionari. El model d'anuncis vigents es basa en una infraestructura completa que lliura els anuncis personalitzats. Pera això, es pot recopilar una gran quantitat de dades d'ús, agregar, processar i vendre molt ràpidament. Malauradament, aquestes pràctiques generen riscos de privadesa. Donada la complexitat de l'operació de les plataformes d'anuncis, els riscos de privacitat es poden estudiar des de diverses perspectives. Naturalment, els esforços per desenvolupar aquests problemes de privacitat es concentren en una entitat, tecnologia, comportament o context específic. Però aquest enfocament subestima els beneficis d'una perspectiva més àmplia d'un problema integral. Molts mecanismes de protecció han estat proposats des de la indústria i l’àmbit acadèmic. Els més populars apliquen estratègies radicals que obstrueixen la distribució d'anuncis, afectant seriosament l’ecosistema d'anuncis. També es pot modificar significativament l’ecosistema, el que no és factible per la seva conflictivitat. Així, amb la finalitat de fomentar l'adopció de protecció de privacitat, és fonamental plantejar solucions orientades a equilibrar les necessitats de privacitat amb el model de negocis de la web. Inicialment, la tesi ofereix una visió amplia dels riscos de privacitat i els mecanismes de protecció a ecosistema d'anuncis en línia. Això es pot aconseguir basant-se en una revisió de la infraestructura i tecnologies subjacents en aquest context. Analitza sistemàticament les amenaces i potencies atacants. A continuació es revisa exhaustivament els mecanismes de privacitat més rellevants, i es classifica i es compara segons les garanties de privacitat que s'ofereixen i el seu possible impacte a la web. Seguidament, s'estudia els riscos de privadesa derivats de les ofertes en temps real, una tecnologia clau del sistema d'anuncis en línia modern. Experimentalment, s'inverteixen els riscos del procés de distribució de dades d'ús, part del sistema basat en licitacions de la publicitat en línia. Es proposa un sistema que regula la distribució de dades d'ús a tercers, depenent del seu comportament previ. Això consisteix en reduir el nombre d’agències anunciants que rebin dades d'ús. Per mitigar l’impacte sobre els ingressos del sistema d'anuncis, aquesta reducció és malaltia i l'objectiu de maximitzar els declaracions ingressades. Experimentalment, es troba que el sistema proposat corregir els comportaments maliciosos, millorant la privacitat dels usuaris. Finalment, s'analitza l'impacte del rastre i la publicitat en línia des de la perspectiva iberoamericana. Estudiem el rastreig de tercers i allò relacionat amb els anuncis que se generen en llocs web locals en aquesta regió heterogènia. Trobem que la ubicació de l'usuari en aquest context afecta la privacitat de l'usuari ja que aquest rastreig varia de país a país, tot i que el nombre total d'entitats darrere d'aquest transit sembla estable. El tipus de contingut afecta també el nivell de rastreig: llocs web de noticies o de compres generen més transit cap a tercers i aquesta intensitat s'exacerba en els llocs més populars.

Full textRhapsody is a Model-Driven Development (MDD) tool for embedded and real-time system design. The purpose of this thesis is to determine if Rhapsody can be used for software development on small processor platforms such as the Atmel AVR. Rhapsody is normally used on platforms running an operating system. Therefore certain adaptations are needed in order to use it on platforms without an operating system. These adaptations and their affect on the usability of the tool, advantages and disadvantages are all studied while porting AVR-software to Rhapsody on one of CC Systems products, the robust on-board computer CC Pilot XL II.
Rhapsody är ett verktyg för modelldriven utveckling och design av inbyggda system och realtidssystem. Syftet med detta examensarbete är att undersöka om Rhapsody kan användas för att utveckla mjukvara till små processorplattformar som Atmel’s AVR. Då Rhapsody normalt används till plattformar med ett operativsystem behöver vissa modifieringar göras för att möjliggöra utveckling mot plattformar utan operativsystem. Dessa modifieringar, deras för och nackdelar samt påverkan på utvecklingsprocessen undersöks medan AVR-mjukvara porteras till Rhapsody. Mjukvaran som porteras är en del av styrsystemet till en av CC Systems produkter: CC Pilot XL II, en robust fordonsdator.

Full textKrav på kortare ledtider, kundanpassat byggande och hög kvalitet på leveranser tvingar byggföretagen att systematisera arbetet i sina produktionsled. Genom att återanvända processer och tekniska lösningar kan det dagliga arbetet utvecklas inom plattformar för industriellt bostadsbyggande. Produktplattformar med syfte att stödja effektiv design och produktutveckling baseras på strategier för tillverka mot order produktion. Projekteringsfasen, som en integrerad del avbostadsbyggandets produktionskedja, har identifierats som avgörande för att erhålla en effektiv produktion. I projekteringsfasen kombineras fördefinitioner från plattformen med projektets krav. Syftet med denna avhandling är att beskriva hur bostadsplattformar kan systematiseras, och föreslå ett ramverk för användning och utveckling av plattformar över tid.För att fördjupa kunskapen om hur plattformar används och utvecklas i bostadsprojektering har fallstudier genomförts genom insamling av data via intervjuer, observationer och arkiv hos två olika företag. Ett svenskt industriellt bostadsbyggande företag med hög grad av fördefinering för prefabricerad produktion. Det andra företaget använder flera plattformar och industrialiserade metoder för platsbyggande produktion. Projekteringsarbete har studerats i över sextio bostadsprojekt genom att följa projektledare, ingenjörer och plattformsutvecklare i deras dagliga arbete. Användandet av fördefinierade funktionskrav, komponenter, processer och relationer har analyserats mot plattforms och designteorier.Forskningsresultatet visar att kreativt och systematiskt arbete kombineras i en konstruera-mot-order kontext. Kombinationen är nödvändig för produktens unikitet, och därför är balansen mellan repetition och variation viktigt för förståelse om och andvändande av plattformar i husbyggnadsprojekt. Ständigt föränderliga krav inom byggandet hindrar en fullt fördefinierad plattform. Långa cykeltider i bostadsbyggandet ställer krav på ett kontinuerligt flöde av kunskap mellan plattform och det dagliga arbetet inom byggprojekten. Plattformsversioner och produktvarianter blir ofta icke-funktionella i en konstruera-mot-order kontext, metoder behövs därför för att stödja flödet. Forskningsresultaten visar på att projekteringsarbete, integrerat i bostadsbyggandets leveranskedja, är en källa för erfarenhetsåterföring i utveckling av en plattform.Slutsatserna visar att en förändring mot effektivt kundanpassat bostadsbyggandet är möjlig om plattformar används tillämpade i projekt med stödjande metoder och kontinuerlig erfarenhetsåterföring från byggprojekten till plattformen. Däremot, finns det en risk att plattformar fördefinieras utan att reflektera över konsekvenserna. Användning av fördefinierade processer skulle kunna begränsa innovationsförmågan, öka risken för imitation och skapa förändringsmotstånd inom organisationer. Detaljering av komponenter i en bostadsplattform kan begränsa produktutbudet och minska marknadssegmentet. Studien visar också att fördefinitioner kan leda till obalanserad fokusering på byggbarhet istället för funktionalitet för kunden.

Full textThis paper describes a system for locating oil rigs based on a general location algorithm. The problem consists in maximizing the net present revenue value of the project arbitrating discharge values for each of the production wells involved. Due to the high degree of uncertainty in determining the initial flow rate of each well it is assumed a percentage that will establish minimum and maximum levels of flow, trying to correct possible errors related to the initial collection and interpretation of data. In addition, a random factor is introduced when calculating the initial flow in order to increase reliability in determining the possible location of the platform. From these initial flow rates and also the flow over the lifetime established for the wells, the net present revenue value of each well and consequently the percentage of participation of these wells in proximity to the platform will be calculated. This percentage represents the weight of each well in determining the final location of the oil platform. The surface of the seabed is assumed similar to a plan, so no barriers are considered on the links between the various wells and the platform. A sample problem is solved to test the system described.

Full textThe objective of this thesis was to develop multifunctional tools for cancer theranosis, particularly based on nanotechnology. The work is based on the premise of monomolecular multimodal platform that aims to create the building blocks that can be used for the synthesis of functionalized nanoparticles, bioconjugates or targeted small molecular imaging probes.The initial work focused on the synthesis of the chelator based silane precursors. These novel precursors were employed for the functionalization of AGuIX nanoparticles and have also been implicated in a one pot AGuIX synthesis. Radiolabelling of these nanoparticles was performed with the aim to evaluate the stability of these nanoparticles under physiological conditions. Furthermore, these nanoparticles were investigated in TSA tumor model in order to evaluate their pharmacokinetics, biodistribution behaviour and value in PET-MRI imaging.In the second part of the work, building blocks/ligands have been developed and successfully deployed for the functionalization of gold nanoparticles. Multimodal ligands containing different combinations of chelators, targeting moieties, functional groups and dyes were synthesized. Gold nanoparticles for PET-MRI and PSMA targeting SPECT imaging were further radiolabeled (64Cu/111In) and showed excellent stability. PSMA targeting ligand exhibited good affinity towards PSMA, whereas the in vivo studies of the gold nanoparticles for PET-MRI in TSA tumor model demonstrated good pharmacokinetics properties, underscoring their potential in cancer imaging and radiotherapy.The latter half of the thesis work focusses on the development of PET-Optical probes for PSMA positive cancer targeting imaging using small molecular probes, and for bioconjugation to antibody fragments and nanoparticles. A PSMA targeting probe based on NODAGA and IR-783 dye has been developed and characterized for its affinity, photophysical and radiolabelling properties. Likewise, a similar probe bearing a maleimide handle has been successfully used for the site-specific labelling of trastuzumab Fab’ fragments and functionalization of AGuIX nanoparticles. These bioconjugates and the nanoparticles have been thoroughly characterized and evaluated in relevant biological models to highlight their value in cancer theranosis

In this thesis, we present two lines of research developing tools that, in addition to being of independent theoretical interest, yield improved protocols for secure out-sourcing of computation: Succinct Garbling Schemes. A garbling scheme is a way to encode a program P and input x as P̃̃ and x̃ such that P̃ can be evaluated on i to obtain P(x), but (P̃, x̃) reveals nothing more than P(x). We devise an efficient garbling scheme, based on the recent notion of indistinguishability obfuscation, in which the RAM running time and space usage of P on x are each the same as for P̃ on ,x̃. No-Signaling Multi-Prover Interactive Proofs. A multi-prover interactive proof (MIP) is a protocol by a which a "verifier" can ascertain the truth of a mathematical statement by interacting with two or more "provers" that cannot communicate with each other. We devise an MIP that achieves better efficiency and stronger soundness guarantees than previous constructions. In terms of efficiency, our MIP allows proving many statements with roughly the same (small) communication complexity as is required to prove a single statement. The soundness guarantee is that the verifier cannot be fooled even by malicious provers that can, in a very limited sense, collude in their messages to the verifier. The latter guarantee crucially enables an application to delegation of computation. Specifically, we obtain a protocol by which a weak device can outsource expensive computations to a powerful but untrusted server, while being assured that the computation is performed correctly.

Full textIn dense cluttered environments, autonomous physical agents will face many challenges including limited routes, obstructed sensors, and limited communication. Equipping the agents with inter-agent communication alleviates some of the issues, but providing a mechanism for forming groups allows the agents to work together efficiently by avoiding congestion in tight areas and providing redundancy to accomplish a task. This thesis presents a framework for decentralized collaborative group formations and a framework for augmenting that with a more strategic centralized approach. This thesis will investigate a strategy for the formation of hierarchical ad-hoc groups that provide a simple interface for joining and splitting groups. After formation these groups will use peer to peer algorithms to share sensor data and perform distributed task allocation within the group. The groups can either be controlled by a static base-station or use a decentralized framework if communication to the base-station is lost. When communication is restored, the peer to peer algorithms will be used to spread the data to as many agents as possible to avoid data loss. A radio propagation model is also presented to simulate communication in indoor and simulated environments, as well as estimated propagation for use in path planning. This framework will also allow the agent's high level decision making to modify its role depending on group consensus.

Full textOs avanços na tecnologia de fabricação de circuitos integrados tem permitido a implementação de sistemas inteiros em um único chip, combinando alto poder de processamento e baixo consumo em uma pequena área. Os chamados Multiprocessor System-on-Chip (MPSoc) incluem multiplos processadores heterogeneos, estruturas complexas de interconexão e componentes de propriedade intelectual fornecidos por terceiros. Esta tecnologia permitiu o surgimento de dispositivos portateis como telefones celulares, PDAs, dispositivos multimídia que combinam a portabilidade com a capacidade de antigos computadores desktop. Contudo, a especificação e validação destes sistemas se tornou uma tarefa muito difícil. Existe um gap entre a especificação do sistema em alto nível e a implementação em uma plataforma multirprocessador. Este gap entre a especificação e a implementação não é tratado de forma adequada pelas metodologias e ferramentas existentes. Tendo como consequencia atrasos no ciclo de desenvolvimento e erros que podem comprometer o projeto. Nesta tese é atacado o problema de implementação da comunicação modelada a nível de sistema em plataformas multiprocessadores. As contribuições deste trabalho são: (1) uma nova abordagem para a modelagem de plataformas multiprocessador; (2) uma metodologia para o mapeamento de comunicação na plataforma; (3) suporte de análise para avaliação da implementação da comunicação. As metodologias e ferramentas propostas foram validadas utilizando-se dois estudos de caso. O primeiro uma aplicação com múltiplas comunicações e o segundo uma aplicação multimídia

Full textO fenómeno das plataformas é central para o paradigma socioeconómico atual. Em poucas décadas, o modelo de negócio das plataformas conseguiu alterar fundamentalmente múltiplas indústrias. É um tópico que, embora extensivamente estudado pelos investigadores, ainda produz descobertas. O presente estudo pretende contribuir para esse esforço, explorando o papel das parcerias na internacionalização das plataformas digitais, dos pontos de vista da Gestão Estratégica e de Gestão de Negócios Internacionais. A questão de investigação sobrejacente a este estudo é formulada com base numa revisão de literatura sobre o modelo de negócio das empresas plataforma e o seu processo de internacionalização: Como é que os ecossistemas de plataforma locais são desenvolvidos e estabelecidos? Para responder a esta questão, é desenvolvido um caso de estudo explanatório com base em dois casos altamente contrastantes: a Microsoft Portugal e a Too Good To Go Portugal. Este trabalho descobre que as parcerias podem desenvolver ecossistemas de plataforma e criar oportunidades de negócio em mercados estrangeiros. As plataformas capacitam os seus parceiros com ferramentas e conhecimento por forma a desenvolver e enriquecer ecossistemas. O termo parceiro inclui múltiplas empresas a desempenhar diversos papéis, organizadas de forma hierárquica. As plataformas alavancam parcerias locais e, por vezes, internacionais, aumentando a competitividade local. Ainda assim, parcerias internacionais podem não se traduzir diretamente em parcerias locais. Finalmente, fatores como a credibilidade da empresa plataforma no mercado e o seu alinhamento estratégico com o contexto ético, social e ambiental, podem ter uma influência positiva na sua difusão em mercados e ecossistemas no estrangeiro.
The platform phenomena is central to the contemporary socio-economic paradigm. In a few decades, the platform business model has managed to disrupt and fundamentally change multiple industries. Although this topic is being thoroughly studied by contemporary academia, it still yields discoveries. This research aims to contribute to that effort by exploring the role of partnerships in the internationalization of digital platforms, from the points of view of Strategic Management and International Business. It draws from a literature review on the platform business model and the internationalization process of platform firms to formulate an overarching research question: How are local platform ecosystems established and developed? To answer this question an explanatory case-study based on two highly contrasting cases: Microsoft Portugal and Too Good To Go Portugal is developed. This work finds that partnerships can develop platform ecosystems and create business opportunities in foreign markets. Platform firms invest and empower partners with tools and knowledge. Partner is a catch-all term that includes multiple firms playing diverse roles, organized in hierarchical fashion. Platforms can leverage on local and, sometimes, international partnerships to boost local competitiveness. Yet, international partnerships may not translate directly into local partnerships. Finally, factors such as the market credibility of the platform firm and its strategic attunement to the social, environmental, and ethical context may have a positive influence on platform diffusion in foreign user networks and ecosystems.

Full textLas tecnologías relacionadas con el diagnóstico son un campo importante para el progreso de la medicina y el cuidado de las salud. Por ejemplo, estas tecnologías pueden aportar valiosa información para el tratamiento y diagnóstico temprano de enfermedades, seguridad en alimentos y monitoreo del medio ambiente. En este contexto, los sistemas de biosensado son una herramienta muy prometedora que permite la detección de agentes con interés diagnostico. Dado que la nanotecnología facilita la manipulación y control a la nanoescala, los sistemas de biodetección basados en nanotecnología poseen poderosas capacidades que pueden ser explotadas en las tecnologías relacionadas con el diagnóstico. En esta tesisis se han estudiado las ventajas que aporta la integración de nanomateriales a la tecnología de microarrays, generalmente en términos de sensibilidad. Particularmente, se ha estudiado el desempeño de la integración de nanocristales semiconductores (NS) para la detección de un biomarcador relacionado con Alzheimer en formato microarray. En dicho microarray se ha observado un importante rendimiento, mostrando un excelente limite de detección de 62 pg mL-1, el cual supera a otros metodos convencionales de detección como el ELISA (470 pg mL-1). También se ha analizado un banco de diluciones de una muestra de suero humano con precisión y exactitud aceptables (Anal. Chem. 2012, 84:6821). Por otra parte, ya que el óxido de grafeno (OG) es un material muy novedoso y la tecnología de microarrays depende de señales ópticas, se ha documentado ampliamente el estado del arte sobre el uso de (OG) en en el campo del biosensado óptico (Adv. Mater. 2012, 24:3298). Adicionalmente, se ha estudiado al OG como un desactivador de fluorescencia de NS altamente eficiente, presentando una eficiencia en la desactivación de NS de casi el 100%. Finalmente se ha aplicado dicha interacción entre NS y OG para diseñar un sistema de transducción altamente sensible (Carbon 2012, 50:2987 ). Esta investigación tiene por objetivo demostrar las ventajas y el potencial que posee la fusión entre los nanomateriales y la tecnología de microarrays como un sistema aplicado al campo del diagnóstico

Full textThe latest advances on reconfigurable systems resulted in FPGA devices with enough resources to implement multiprocessing systems with more than 100 soft-cores on a single FPGA. In this thesis I present how to implement solutions based on such systems and I present two scenarios where those kind of sytems would be valuable. FPGAs are increasingly being used in HPC computing as they can bring higher energy efficiency than other alternative architectures such as CPUs or GPGPUs. However, the programmability barrier imposed by HDL languages is a serious drawback that limits their adoption. The recent introduction of OpenCL toolchains for FPGAs is a step towards destroying the barrier, but still produce application specific designs that cannot be reused for other general purpose computing unless the platform is reconfigured. Building many-soft-cores using simple hardware accelerators can bring performance and energy efficiency and still provide a general purpose system to be used for different applications. To make it possible the current FPGA toolchains has been complemented to add support for fast many-soft-core platform description, provide convenient parallel programming models, and efficient methods to optimize the designs. On the other hand I show how the same methods can be applied to implement a system using a task isolation approach to meet the requirements of a hard real-time safety critical system.

Full textThis thesis ties some electrochemical aspects of development and fabrication of an analytical system on a microchip together. These aspects develop through the fundamentals of amperometric detection in microsystems and microfabrication via the interaction of electrochemical detection and electrophoretic separation finally to the interfacing of a microsystem to the macro world.
Paper I deals with amperometric detection in microscale systems and describes the fabrication of the necessary on-chip microelectrodes together with fluidic channels in silicon. It was furthermore studied, if the interelectrode distance of some μm could be used to improve the sensitivity in amperometric detection by employing redox cycling.
Papers II, III and IV deal with the effect of a high voltage field on amperometric detection. In analytical microdevices typically an electrophoretic separation step (e.g. capillary electrophoresis, CE) precedes the detection. The interference of the CE high voltage with the amperometric detection potential is often considered one of the main hindrances for an effective combination of these techniques. In paper II one reason for the observed disturbing potential shift was elucidated. It was shown that positioning of working electrode and reference electrode on an equipotiental surface eliminates this problem. Paper III reports an application of this technique. In paper IV it could be shown that this approach could further be used to significantly reduce the instrumental requirements for amperometric detection in CE.
Papers V, VI, VII, finally discuss the interfacing of low volumetric flows that typically occur on microanalytical devices to other techniques. Both, interfacing from liquid to liquid phase (μLC to CE in paper V) and from liquid to gas phase (CE to MS in paper VI and VII) were discussed. Electrochemical methods are used in this context to evaluate the stability and, in paper VI and VII, to increase the understanding of underlying processes of corrosion.

Full textFrom August 24 to 26 1992, hurricane Andrew moved through the Gulf of Mexico with sustained winds of 140 miles per hour. Thirty-six major platforms suffered significant damage, of these, ten were completely toppled and twenty-six were leaning significantly or had significant topside damage.
Structures "H" and "K" were bridge-connected platforms, located in the ST151 field of the South Timbalier area of the Gulf of Mexico, platform "H" collapsed during Andrew, while "K" survived undamaged. They were both designed, fabricated, and installed in the early 1960's.
A push-over analysis, using the program USFOS was used to estimate the ultimate strength of the two structures in three direction: end-on, diagonal and broadside.
In the first series of analyses, all the primary members such as legs, vertical and horizontal braces, piles, soil, conductors and deck structure were precisely defined with appropriate finite elements as well as secondary members such as conductors guides barge bumpers. In the second series of analyses it was assumed that there was no horizontal or vertical movements at the level of the mudmat. In the third series of analysis the model used in the first series of analysis was modified by increasing stiffness and resistance of the piles 10 times. Finally a fourth model was investigated in which the soil resistance of the mud-level horizontal members is modelled. (Abstract shortened by UMI.)
