Data Access Statement: This research did not use any experimentally generated data or data from any publicly available dataset. Model definitions (including the specified probability distributions) and parameter values (including the initialization parameters) provided in the paper are adequate for reproducing the exact qualitative behavior of the algorithms illustrated in the paper.© Copyright 2022 The Authors. Approximate filtering algorithms in nonlinear systems assume Gaussian prior and predictive density and remain popular due to ease of implementation as well as acceptable performance. However, these algorithms are restricted by two major assumptions: they assume no missing or delayed measurements. However, practical measurements are frequently delayed and intermittently missing. In this paper, we introduce a new extension of the Gaussian filtering to handle the simultaneous occurrence of the delay in measurements and intermittently missing measurements. Our proposed algorithm uses a novel modified measurement model to incorporate the possibility of the delayed and intermittently missing measurements. Subsequently, it redesigns the traditional Gaussian filtering for the modified measurement model. Our algorithm is a generalized extension of the Gaussian filtering, which applies to any of the traditional Gaussian filters, such as the extended Kalman filter (EKF), unscented Kalman filter (UKF), and cubature Kalman filter (CKF). A further contribution of this paper is that we study the stochastic stability of the proposed method for its EKF-based formulation. We compared the performance of the proposed filtering method with the traditional Gaussian filtering (particularly the CKF) and three extensions of the traditional Gaussian filtering that are designed to handle the delayed and missing measurements individually or simultaneously.10.13039/501100001409-Department of Science and Technology (DST), Government of India, through Innovation in Science Pursuit for Inspired Research (INSPIRE) Faculty Award (Grant Number: DST/INSPIRE/04/2018/000089

Exporting the Canon: The Mixed Experience of the Dutch Bibliotheca Neerlandica (1954-1969)

In the 1950s, for reasons of cultural diplomacy, a Dutch quasi governmental organisation, the Stichting ter Bevordering van de Vertaling van Nederlands Letterkundig Werk (The Foundation for the Promotion of the Translation of Dutch Literary Works) served by its bestuur (board), was established to raise awareness of its literature abroad. Its first key project involved translating a series of works called the Bibliotheca Neerlandica into English and to do this, the board established contacts with academics, translators and publishing companies. The purpose of this original research is to map the process of the export of Dutch language classics in the 1960s and to ascertain how they relate to the canon of Dutch language and literature. My methodological approach uses qualitative and quantitative research methods and involves isolating the three literary participants of the project, the board, the translators and publishers to enable me to examine their experiences. I use internet analysis and archival research to both scrutinize the micro-history of the board and the formation of volumes for export as well as to clarify the canon of Dutch literature and its role regarding international cultural diplomacy. My findings demonstrate the complexity of such a cross-cultural undertaking where internal strategic and organisational shortcomings and a lack of planning within an unfavourable external context combined to undermine the Bibliotheca Neerlandica’s fortunes. These are underlined by an influential chairman who selected works based on personal preferences, an ambiguous contract which made the onus of the works’press ready and final translations unclear, poor sales figures and the financial instability of the Heinemann publishing company which affected the 17 planned titles of the Bibliotheca Neerlandica

Novalis's idea of "Experimentalphilosophie" : a study of Romantic science in its context.

PhDThis thesis seeks to examine Novalis's philosophy of practical knowledge and to position it within the context of the work of other Romantic natural philosophers and some aspects of contemporary science. His views on Ritter's galvanism and the latter's significance for his thought in general are treated here for the first time in full. Contrary to most previous views, it is argued that a major part of Novalis's outlook stems from his concept of practical knowledge and his reflection over the term "experiment", which proves to be an extremely complex and central idea in his thought. It is shown how this philosophy of his finds most explicit expression in the idea of a symbolic notation or a "phenomenal" calculus. These notions merge in Novalis's idea of productive "Plastisirung". Particular attention is paid to the symbolic use of phosphorus in the pneumatic debate and Ritter's galvanic interpretation of the nerve. Beyond contemporary science, it is further shown how broad an historical base Novalis channels into his notion of practical knowledge. This should lead to a clearer understanding of Novalis's position within Romantic natural philosophy, his debt to tradition, and his originality. In the light of these findings, it is argued that Novalis's concern for practical knowledge provides the basis for a possible form of consensus in his thought. It is shown that there is an increasing tendency in his writings away from a programme for classifying knowledge in general towards the idea of individual knowledge and the case study, as is exemplified in his reception of Ritter's work. It is also advanced that Novalis's notion of practical knowledge is a significant methodological statement of early Romantic science, which also puts a new perspective on thinkers such as Goethe, Humboldt, Schelling and Ritte

The Relational Bases of Lifestyle Similarity and Clustering of Local Populations.

Lifestyle clustering is explored as a form of stratification within local populations. The concept of lifestyle cluster is juxtaposed to concepts of lifestyle segment, class, status group, strata, and other models of social inequality, which are argued to be variants of the lifestyle cluster concept. A relational theory is outlined, explaining lifestyle clustering as a result of basic social and psychological processes operating on the distribution of various forms of capital. Marx’s locus of economic capital in relations of production is expanded to conceive of the locus of all forms of capital in social relations generally. Capital situation is thereby equated to network position, placing the network analytic concept of equivalence at the root of lifestyle clusters and class analysis. The resulting model focuses on lifestyle distinction and habitus, following Bourdieu, but welds this framework to an explicitly social network methodology and perspective of relationality. It is argued that relations with specific others serves as a proxy for relationality generally. A method is developed and undertaken for testing model expectations about the distribution of lifestyle in a local population and how that distribution correlates with positions in the local social network of a rural U.S. community. A Social Network Survey is designed and administered. Relation type equivalence is developed as a alternative to regular equivalence, which is computationally prohibitive for such a large network. Lifestyle data for N=1203 persons in a network that includes partial information for over 13,000 nodes were analyzed. Lifestyle profiles are offered for about 50 clusters. Evidence of lifestyle ‘clumpiness’ is found, but no evidence is found of cluster separation or boundedness. Relation Type Equivalence is found to have moderate predictive power with lifestyle cluster membership and dyadic lifestyle similarity. Occupation, age, and gender are also found to have an impact. Asset ownership variables are found to have very little impact. Methodological limitations of the project are discussed.Ph.D.SociologyUniversity of Michigan, Horace H.
