A set of nine principles for distributed-design information storing
No full textThe issues of distributed working are many, with problems relating to information access and information acquisition the most common (Crabtree et al., 1997). Keeping track of project and team information is becoming more complex as design is increasingly being carried out collaboratively by geographically dispersed design teams across different time zones. The literature notes that little prescription or guidance exists on information management for designers (Culley et al., 1999) and Hicks (2007) highlights a relative lack of overall principles for improving information management. Additionally, evidence from earlier studies by the author into ‘How information is stored in distributed design project work’ reinforces the need for guidance, particularly in a distributed context (Grierson, 2008). Distributed information collections were found to be unorganised, contained unclear information and lacked context. Storing and sharing of distributed information was often time consuming and the tools awkward to use. This can lead to poor project progress and can impact directly on the quality and success of project outcomes (Grierson et al., 2004, 2006). This paper seeks to address these issues by presenting the development, implementation and evaluation of a set of Principles and a Framework to support distributed design information storing in the context of a Global Design class. Through both quantitative and qualitative evaluation methods the Principles were found to help in a number of ways – with the easy access of information; the structuring and organising of information; the creation of an information strategy; the making of information clear and concise; the supporting of documentation during project work; and the strengthening of team work; all helping teams to work towards project outcomes
From Visual Poetry to Digital Art: Image-Sound-Text, Convergent Media, and the development of New Media Languages
No full textThis research arises from my practice as a professional artist and my concern with issues of language and communication, particularly, the investigation of ways that arouse emotion and rational thought at once through language. Visual Poetry is a form of expression, which provokes both, and I saw the potential to expand its underlining principles further with the emergence of new technologies. With the digital medium, the main elements of visual and sound poetry: image, sound and text, can now be incorporated into the same piece of work.
The aim of this study is to explore new digital communicative systems that interweave visual, oral and semantic elements of language, to produce new media languages where the pre-linguistic and linguistic maintain their symbiotic identities. This study examines theoretical and artistic concerns emerging from the area in-between, which is created by interlacing image, sound and text in the same artwork.
It addresses the following series of questions:
How to transfer the main concepts from Visual Poetry to Digital Art?
How does computer technology transform image, sound and text to create new media languages?
What is the role of the author, reader, writer, producer in these new interactive textualities of image, sound and text?
How has this affected the new conventions of reading, looking, producing, using and thinking?
What does the digital add to the interactivelexts of Visual Poetry? What new meanings and processes of thinking, understanding and interpretation are appearing?
In which way do new technologies enhance the collaborative nature of practice?
This investigation brings knowledge from other disciplines into the art field and it explores different serniotic models such as the linguistic the visual and the aural. It blurs the barriers between the visual and the linguistic: between different art forms such as fine art, visual poetry and sound art/poetry in a new digital and technological arena. It questions the conventions applied to these critical areas with the aid of the new tools and critical concepts available through digital technology. This study challengest he viewer/listener/userw ith an interface of signsf rom different languages and serniotic systems: the visual (still and moving images), the audible and the linguistic, to participate and explore the multiple possibilities within a work. This investigation seeks to contribute to a new body of knowledge in the
development of the areas of Visual Poetry, Digital Art and the new genre of Electronic Poetry, by creating new, innovative, digital artworks for which, as a new form of expression, critical and analytical conventions are still in the process of development
La redazione cristiana del Testamento di Salomone
No full textIn questo studio si riesaminano i vari livelli redazionali del Testamento di Salomone, pseudepigrafo sinora non molto studiato, in cui si narra come Salomone sia stato aiutato da alcuni demoni nell'edificazione del tempio di Gerusalemme. Il testo ha avuto una fase compositiva e redazionale complessa, in cui si sono sovrapposte componenti giudaiche e cristiane. Sono qui presi particolarmente in considerazione alcuni elementi del lessico e, per quanto riguarda temi e contenuti, sono esaminate le riscritture del testo biblico (particolarmente di 1Re 4, 29-12, 24) e i rapporti con la letteratura cristiana antica, di cui l'autore mostra di avere buona conoscenza.The Testament of Solomon (TS) is a Greek pseudepigraphon recounting how King Solomon was helped by some demons to build the Jerusalem Temple. The story deeply reworks 1 Kings 4, 29-12, 24 and displays all the features of the ‘Rewritten Bible’. In the complex textual tradition of TS, various redactional
levels can be detected, both Jewish and Christian. It seems that its textual nucleus, including some demonological and magical materials, originated in Jewish traditions; nonetheless, in its full redaction the text is certainly Christian. The aim of the present study is to show how the vocabulary and concepts shared by TS with the New Testament cannot be ascribed just to the same linguistic background, or to traditions received orally, but that the Christian author had a direct and good knowledge at least of the Synoptic Gospels
Generation&Transmission Planning and Electricity Market: the Role of TSO
No full textIn a competitive environment the generation and transmission systems planning (GS&TS-P) becomes more complex and needs new approaches, criteria and models. Referring to the attribute named flexibility of the transmission system in respect of generation changes, and to some validated indexes for its evaluation (Uncertainty Scenario Flexibility Indexes - USFI), the author proposes the integration of this attribute in a Generation System-follows-Transmission System planning, stressing the importance of this stage for the Highly Developed Power Systems (HDPS) such as the Italian National Transmission System (INTS)
Between panther and the angel: Geir Campos Rainer Maria Rilke’s critical reception in Brazil
No full textA geração de 45 caracterizou-se, entre outras questões, pela eleição de grandes nomes da literatura europeia como paradigma da lírica, como T.S. Eliot, Paul Valéry e Fernando Pessoa. Entre estes, o poeta de língua alemã Rainer Maria Rilke (1875-1926) passou, a partir do final dos anos 40, a ser lido, traduzido e comentado no Brasil. Ainda que parte da crítica defenda que os poetas da geração de 45 baseavam-se apenas na sua obra tardia, de Sonetos a Orfeu e Elegias de Duíno, a leitura dos poemas mostra-se muito mais assistemática e baseada em uma interpretação biografizante. Entre estes poetas, Geir Campos destaca-se pelo trabalho prematuro de traduzir os poemas de Rilke, ao mesmo tempo em que a escolha destes poemas e modificações no trânsito entre a língua-fonte e a língua-objeto forjam uma determinada imagem do autor traduzido, que encontra reflexos na própria obra poética de Campos.The Brazilian post war poets regarded some European authors, like TS Eliot, Paul Valéry and Fernando Pessoa, as paradigms of lyrics. Around the late 1940s, the German poet Rainer Maria Rilke (1875-1926), one of those praised writers, began to be read, translated and commented in Brazil. Even though some critics argue that the Brazilian poets at that time where focused solely in Rilke’s late works, Sonnets to Orpheus and Duino Elegies, those readings uncloak themselves mainly random and biographical. Amongst these Rilke’s Brazilian readers, the poet Geir Campos stands out for his early translations of Rilke\u27s poems. Through selection and small changes between original and translation, Campos builds an image of the translated author. Such imagery reappears in Campos\u27 own poetic work
Novel concepts, systems and technology for sludge management in emergency and slum settings
No full textManagement of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focuses on addressing the existing challenges and gaps in sludge management, particularly the management of faecal sludge that is generated in the densely populated areas, through innovative concepts and technological development. To assess the current status of decentralized management of faecal sludge, a review of the existent (emergency) sanitation practices and technologies was conducted. In the study, the gaps and opportunities in technological developments for sanitation management in complex situations was identified. The need for an innovative sludge management system led to the development of the “emergency sanitation operation system, eSOS”. This concept proposed and demonstrated the application of modern innovative sanitation solutions and existing information technologies for sludge management. In addition, as a component of the eSOS concept, a sludge treatment system based on microwave irradiation technology, which forms the core of this research, was developed and tested. The microwave technology study was carried out in two stages. The first stage involved preliminary and validation tests at laboratory scale using a domestic microwave unit to assess the applicability of the microwave technology for sludge treatment. Two sludge types, namely blackwater sludge, extracted from highly concentrated raw blackwater stream, and faecal sludge, obtained from urine diverting dry toilets, were tested. The results demonstrated the capability of the microwave technology to rapidly and efficiently reduce the sludge volume by over 70% and decrease the concentration of bacterial pathogenic indicator E. coli and Ascaris lumbricoides eggs to below the analytical detection levels. Basing on these results, a pilot-scale microwave reactor unit was designed, produced and evaluated using waste activated sludge, faecal sludge, and septic sludge, which formed the second stage of the study. The results demonstrated that microwave treatment was successful to achieve a complete bacterial inactivation like in the laboratory tests (i.e. E. coli, coliforms, staphylococcus aureus, and enterococcus faecalis) and a sludge weight/volume reduction above 60%. Furthermore, the dried sludge and condensate had a high energy (≥ 16 MJ/kg) and nutrient contents (solids; TN ≥ 28 mg/g TS and TP ≥ 15 mg/g TS; condensate TN ≥ 49 mg/L TS and TP ≥ 0.2 mg/L), having the potential to be used as biofuel, soil conditioner, fertilizer, etc. Overall, in this study the existence of a wide range of regular onsite and offsite sanitation options was revealed that have the potential to be applied for sludge management in the emergencies. Situations with more or less similar characteristics to emergencies such as urban slums can also benefit from these technologies. In addition, the shortfalls experienced in the many current emergency sanitation responses were associated with the often used conventional fragmented approach that does not capture the entire sanitation chain, but rather looks at the individual components separately with emphasis on the containment facilities. An innovative emergency Sanitation Operation System (eSOS) concept was thus introduced in this study that uses and promotes a systems approach integrating all components of an emergency sanitation chain. Furthermore, the study demonstrated that a microwave technology based reactor can be applied for the rapid treatment of sludge in the areas where large volumes of sludge are generated such as slums and emergency settlements.Dissertation submitted in fulfillment of the requirements of the Board for Doctorates of Delft University of Technology and of the Academic Board of IHE Delft Institute for Water Education.BT/Environmental Biotechnolog

No full textTrabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2021Introdução: Em abril de 2020, foi descrita, pela primeira vez, uma síndrome pediátrica temporalmente associada ao Coronavírus 2019 (COVID-19), caracterizada por intensa resposta inflamatória sistémica, que partilhava características com a Doença de Kawasaki e a Síndrome de Choque Tóxico. Esta patologia foi primeiramente denominada Paediatric Inflammatory Multisystem Syndrome-temporally associated with SARS-CoV-2 (PIMS-TS). Objetivo: Descrever a experiência com esta nova síndrome na Unidade de Cuidados Intensivos Pediátricos do Hospital de Santa Maria (UCIPed). Métodos: Revisão dos registos clínicos e recolha de dados dos doentes que cumpriram a definição de caso de PIMS-TS entre abril de 2020 e abril de 2021. Resultados: Foram encontrados 16 doentes, mediana de idades 12 anos; 12 eram rapazes, 11 caucasianos e 8 previamente saudáveis. Oito tinham tido um teste RT-PCR SARS-CoV-2 positivo com uma mediana de 26 dias previamente ao início dos sintomas e todos tinham IgG SARS-CoV-2 positiva. À admissão na UCIPed a mediana da duração dos sintomas foi 5 dias. Os sistemas mais frequentemente atingidos foram o cardiovascular, gastrointestinal e mucocutâneo. A maioria tinha elevação muito acentuada dos parâmetros inflamatórios e cardíacos, com disfunção ventricular esquerda (13), choque (11) e alterações coronárias (1). Todos receberam imunoglobulina, 14 corticosteroides, 3 ácido acetilsalicílico e 1 anticoagulação profilática. Catorze cumpriram antibioticoterapia. Oito necessitaram de oxigenoterapia e 2 ventilação mecânica. Doze necessitaram de suporte aminérgico e 1 esteve em oxigenação por membrana extracorporal veno-arterial (ECMO-VA). A mediana da duração do internamento na UCIPed foi 4 dias. Todos os doentes foram transferidos para a enfermaria, de onde tiveram alta para o domicílio, após uma mediana de 8 dias. Na primeira consulta pós-alta, 10 já não apresentavam qualquer alteração cardíaca. Não se registaram óbitos. Conclusão: Nesta série, embora com resultados semelhantes aos publicados na literatura internacional, salienta-se a moderação na utilização de terapêutica farmacológica e a ausência de mortalidade.Introduction: In April 2020, a newly recognised paediatric disorder temporally associated with Coronavirus Disease 2019 (COVID-19) was described, characterised by a significant systemic inflammatory response, sharing features with Kawasaki Disease and Toxic Shock Syndrome. This condition was first named ‘Paediatric Inflammatory Multisystem Syndrome-temporally associated with SARS-CoV-2’ (PIMS-TS). Objective: To describe the experience with this syndrome of the Paediatric Intensive Care Unit of Hospital de Santa Maria (UCIPed). Methods: Review of the clinical records and data collection of patients fulfilling the case definition of PIMS-TS from April 2020 until April 2021. Results: Sixteen patients were found, median age 12 years; 12 were boys, 11 Caucasian, and 8 previously healthy. Eight had a positive RT-PCR SARS-CoV-2 test with a median of 26 days prior to symptom onset and all had positive IgG SARS-CoV-2. The median duration of symptoms at admission to the UCIPed was 5 days. The most frequently affected systems were cardiovascular, gastrointestinal, and mucocutaneous. Almost all showed a very marked elevation of inflamatory and cardiac parameters, with left ventricular dysfunction (13), shock (11) and coronary abnormalities (1). All received immunoglobulin, 14 corticosteroids, 3 acetylsalicylic acid, and 1 prophylactic anticoagulation. Fourteen had antibiotherapy. Eight required oxygen therapy, and 2 mechanical ventilation. Twelve required aminergic support, and 1 was in venoarterial extracorporeal membrane oxygenation (ECMO-VA). The median length of hospitalisation at the UCIPed was 4 days, having all patients been transferred to the ward after that period, where they stayed for a median length of 8 days before being discharged home. At the first post-discharge visit, 10 no longer presented any cardiac abnormality. No deaths ocurred. Conclusion: In this series, although results are similar to those already published, the author outlines the moderation in choosing farmacologic therapies and the absence of mortality

Electromagnetic Transient-Transient Stability Hybrid Simulation for Electric Power Systems with Converter Interfaced Generation
No full textabstract: With the increasing penetration of converter interfaced renewable generation into power systems, the structure and behavior of the power system is changing, catalyzing alterations and enhancements in modeling and simulation methods.
This work puts forth a Hybrid Electromagnetic Transient-Transient Stability simulation method implemented using MATLAB and Simulink, to study power electronic based power systems. Hybrid Simulation enables detailed, accurate modeling, along with fast, efficient simulation, on account of the Electromagnetic Transient (EMT) and Transient Stability (TS) simulations respectively. A critical component of hybrid simulation is the interaction between the EMT and TS simulators, established through a well-defined interface technique, which has been explored in detail.
This research focuses on the boundary conditions and interaction between the two simulation models for optimum accuracy and computational efficiency.
A case study has been carried out employing the proposed hybrid simulation method. The test case used is the IEEE 9-bus system, modified to integrate it with a solar PV plant. The validation of the hybrid model with the benchmark full EMT model, along with the analysis of the accuracy and efficiency, has been performed. The steady-state and transient analysis results demonstrate that the performance of the hybrid simulation method is competent. The hybrid simulation technique suitably captures accuracy of EMT simulation and efficiency of TS simulation, therefore adequately representing the behavior of power systems with high penetration of converter interfaced generation.Dissertation/ThesisMasters Thesis Electrical Engineering 201
