Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Narrativas e variações do dia triunfal de Fernando Pessoa
No full textFernando Pessoa described his triumphal day, March 8, 1914, as the epiphanic moment of creation of his master Alberto Caeiro. Whereas philologists have underlined the fictional nature of this description, based on features of the manuscripts left by the author, several interpretations aim to preserve the importance of its meaning, by separating the poetic from the factual dimension. The present essay seeks to analyse, in a dialogue with critical literature and providing a revision of material data from the manuscripts, the several narratives by the author on the triumphal day, conceiving them as variations on a theme. Renouncing both the idea of an imaginative construct by Pessoa and of its perfect correspondence to facts, the article proposes to analyse the descriptions of this epiphany as literary modulations of a real event, whose meaning is decisive for an understanding of the foundations of the work.Fernando Pessoa descreveu o seu dia triunfal, 8 de março de 1914, como o momento epifânico de criação do mestre Alberto Caeiro. Enquanto os filólogos têm evidenciado a natureza ficcional desta descrição, com base nas caraterísticas dos manuscritos deixados pelo autor, diversas interpretações procuram salvaguardar a importância do seu significado, separando o campo poético do factual. O presente ensaio pretende analisar, em diálogo com a literatura crítica e partindo de uma revisão dos dados materiais dos manuscritos, as diversas narrativas do autor a respeito do dia triunfal, entendendo-as como variações em torno de um tema. Renunciando tanto a uma ideia de construção fantasiosa de Pessoa quanto à da sua perfeita adequação a factos, propõe-se uma análise das descrições desta epifania enquanto modulações literárias de um acontecimento real, cujo significado é decisivo para uma compreensão dos fundamentos da obra
The DIA-Method for Navigational Integrity
No full textIn this contribution we present a review of the DIA-method to ensure navigational integrity. The DIA-method rigorously combines parameter estimation and statistical testing for the Detection, Identification and Adaptation of multivariate and multiple model misspecifications. We describe the statistical properties of the so-obtained DIA-estimator together with its probability density function. Numerical examples are given to highlight various aspects of the navigational DIA-estimator.Mathematical Geodesy and Positionin
DIA-datasnooping and identifiability
No full textIn this contribution, we present and analyze datasnooping in the context of the DIA method. As the DIA method for the detection, identification and adaptation of mismodelling errors is concerned with estimation and testing, it is the combination of both that needs to be considered. This combination is rigorously captured by the DIA estimator. We discuss and analyze the DIA-datasnooping decision probabilities and the construction of the corresponding partitioning of misclosure space. We also investigate the circumstances under which two or more hypotheses are nonseparable in the identification step. By means of a theorem on the equivalence between the nonseparability of hypotheses and the inestimability of parameters, we demonstrate that one can forget about adapting the parameter vector for hypotheses that are nonseparable. However, as this concerns the complete vector and not necessarily functions of it, we also show that parameter functions may exist for which adaptation is still possible. It is shown how this adaptation looks like and how it changes the structure of the DIA estimator. To demonstrate the performance of the various elements of DIA-datasnooping, we apply the theory to some selected examples. We analyze how geometry changes in the measurement setup affect the testing procedure, by studying their partitioning of misclosure space, the decision probabilities and the minimal detectable and identifiable biases. The difference between these two minimal biases is highlighted by showing the difference between their corresponding contributing factors. We also show that if two alternative hypotheses, say (Formula presented.) and (Formula presented.), are nonseparable, the testing procedure may have different levels of sensitivity to (Formula presented.)-biases compared to the same (Formula presented.)-biases.</p
How Abnormal Are the PDFs of the DIA Method: A Quality Description in the Context of GNSS
No full textThe DIA-method, for the detection, identification and adaptation of modeling errors, has been widely used in a broad range of applications including the quality control of geodetic networks and the integrity monitoring of GNSS models. The DIA-method combines two key statistical inference tools, estimation and testing. Through the former, one seeks estimates of the parameters of interest, whereas through the latter, one validates these estimates and corrects them for biases that may be present. As a result of this intimate link between estimation and testing, the quality of the DIA outcome x̄ must also be driven by the probabilistic characteristics of both estimation and testing. In practice however, the evaluation of the quality of x̄ is never carried out as such. Instead, use is made of the probability density function (PDF) of the estimator under the identified hypothesis, say x̂i, thereby thus neglecting the conditioning process that led to the decision to accept the ith hypothesis. In this contribution, we conduct a comparative study of the probabilistic properties of x̄ and x̂i. Our analysis will be carried out in the framework of GNSS-based positioning. We will also elaborate on the circumstances under which the distribution of the estimator x̂i provides either poor or reasonable approximations to that of the DIA-estimator x̄.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Mathematical Geodesy and Positionin
Benefits, challenges and success factors of water safety plan implementation: A review
No full textDrinking water supply is a preeminent to public health, environmental protection, quality of life, economic activity, and sustainable development. Many disasters are being recorded due to poor water quality every day. In this case, it is essential to assure safe water demand through continuous enhancement and improvement of all practices and processes related to the water supply. The Water Safety Plan (WSP) concept has become a globally recognized and accepted approach to drinking water supply management and operation. This study aims at reviewing the WSP as a risk management approach and the implementation status around the world. In addition, the four success factors of WSP implementation are discussed. The benefits, difficulties, as well as recommendation from recent studies that implemented WSP is presented. The benefits include Improved operational efficiency, improved water quality, reduced consumers, reduced production cost and reduced potential hazardous incidents. However, the main difficulties for effective WSP implementation were lack of staff training, insufficient time and fund were the main challenges. According to a literature scan, the water utilities in Arab gulf region countries do not implement WSP, thus, the author encourages water utilities in these countries to conduct WSP to improve water quality management. © 2022 Global NEST
Distributional theory for the DIA method
No full textThe DIA method for the detection, identification and adaptation of model misspecifications combines estimation with testing. The aim of the present contribution is to introduce a unifying framework for the rigorous capture of this combination. By using a canonical model formulation and a partitioning of misclosure space, we show that the whole estimation–testing scheme can be captured in one single DIA estimator. We study the characteristics of this estimator and discuss some of its distributional properties. With the distribution of the DIA estimator provided, one can then study all the characteristics of the combined estimation and testing scheme, as well as analyse how they propagate into final outcomes. Examples are given, as well as a discussion on how the distributional properties compare with their usage in practice.</p
The Verreville pottery Glasgow: Ceramic Resource Disk 4
No full textThe ceramic material listed, described, and photographed, on the enclosed ceramic resource disk, comes from an archaeological excavation funded by FM Developments Ltd., and carried out in 2005 on the site of the Verreville glass and pottery manufactury in Glasgow by Headland Archaeology Ltd. The ceramic material recovered dates mostly from the Kidston and Cochran periods (see below), and has been sorted by fabric type, decoration, and form, into (18 Folders and 152 Word Files). The excavation material has been assigned to Glasgow Museums and the shards were catalogued using there accession numbers beginning (GM 2006. 05. 1 to 1194). The ceramic assemblage is significant in that it was produced mainly for the North American export market, and therefore many of its products are extremely rare in Britain. The transfer printed patterns illustrated on (Word Files 102 to 129) have been given temporary names by the author, who would be happy to be contacted by ceramic researchers who could fill in the detail
Setting the stage for expertise and exploration: Reframing COALA’s Digital Intelligent Assistant (DIA) within the Diversey factory
No full textIntelligent and connected services have become essential in the manufacturing industry. The surge of these services has even started a new phase of industry; industry 4.0. The COALA consortium aims to develop a service to assist operators within this new industry. The COALA consortium is an European Union Programme and aims to develop a Digital Intelligent Assistant (DIA). The DIA supports operators in situations characterised by cognitive load, time pressure, and little or zero tolerance for quality issues with trustworthy AI components. Diversey is one of the consortium’s partners and perceives COALA’s DIA as a viable solution to their stoppage challenge on their production lines in the factory. These stoppages can be caused by various bottlenecks, which are hard to determine due to the production lines’ complexity and processes. Therefore, this thesis explores how to prepare for AI service adoption within the factory of Diversey. However, management from the Diversey factory has attempted to identify the bottlenecks by collecting production information through operator data entries. Unfortunately, the operators did not provide the tool with quality data entries. Therefore, replacing this tool with the DIA most likely not succeed, especially when the new tool utilises AI technology that requires learning data to generate insights. In order to explore this resistance toward new tools within the factory, I used the frame creation method of Dorst. This method excels at finding innovative solutions for problem definitions with previously unsuccessful attempts. The method explores underlying themes within the context to reframe the problem definition and find new solution spaces. The themes are formulated from interviews with management, eight support staff employees across four departments, a team lead, and six operators. Four themes are generated by analysing the values, interactions, and ‘currency’ exchanged between stakeholders. These themes regarding new tools describe the unclear contributions to operators’ work, the lack of acknowledgement regarding operators’ role and expertise towards production improvements. These themes result in a lack of trust between operators and management, which diminish the willingness to adopt new tools. Additionally, management expresses concerns about the themes expertise and consistency, which are essential to the manufacturing industry. In order to address these themes, COALA’s DIA is reframed as a stage for expertise and exploration. Instead of simply requesting data entries, operators are put in the spotlight where they can showcase their knowledge and expertise. Additionally, this stage provides a space for operators to explore production improvements through collaboration with COALA’s DIA. The framing of the problem definition addresses the data collection aspect of COALA’s DIA. However, AI systems change over time as the systems adapt to the data input. Additionally, the thesis did not assess the users’ perception of the current DIA interface. Therefore, I recommend further research into human-AI interaction with regards to the system’s evolution over time and the interface. Lastly, the themes are generated from one production line’s operators who are experiencing the most stoppages. The themes cannot directly be generalised to other production lines as the number of stoppages, or other contextual factors can influence the themes.Strategic Product Desig
