Decentralized Approximate Bayesian Inference for Distributed Sensor Network
No full textBayesian models provide a framework for probabilistic modelling of complex datasets. Many such models are computationally demanding, especially in the presence of large datasets. In sensor network applications, statistical (Bayesian) parameter estimation usually relies on decentralized algorithms, in which both data and computation are distributed across the nodes of the network. In this paper we propose a framework for decentralized Bayesian learning using Bregman Alternating Direction Method of Multipliers (B-ADMM).We demonstrate the utility of our framework, with Mean Field Variational Bayes (MFVB) as the primitive for distributed affine structure from motion (SfM).Peer reviewe
Fast ADMM Algorithm for Distributed Optimization with Adaptive Penalty
No full textWe propose new methods to speed up convergence of the Alternating Direction Method of Multipliers (ADMM), a common optimization tool in the context of large scale and distributed learning. The proposed method accelerates the speed of convergence by automatically deciding the constraint penalty needed for parameter consensus in each iteration. In addition, we also propose an extension of the method that adaptively determines the maximum number of iterations to update the penalty. We show that this approach effectively leads to an adaptive, dynamic network topology underlying the distributed optimization. The utility of the new penalty update schemes is demonstrated on both synthetic and real data, including an instance of the probabilistic matrix factorization task known as the structure-from-motion problem.Peer reviewe
A Knowledge Distribution Model to Support an Author in Narrative Creation
No full textAdjusting the knowledge of characters and the reader is a critical task for an author in narrative creation. Throughout a narrative, both characters and the reader experience events according to their own timelines and perspectives. They interpret information accumulated through their experience and update knowledge to the narrative-world which the author constructed. In this paper, we present a Knowledge Distribution Model which supports an author in finely controlling the knowledge of characters and the reader. Within the model, the Knowledge Structure is constructed by connecting event, information, and knowledge. The Knowledge State is evaluated as the degree of belief under the knowledge structure. We adopted a probabilistic reasoning model to calculate the knowledge state. The change in knowledge state, defined as Knowledge Flow, is visually presented to the author. We designed a GUI prototype to implement the proposed modeling process, and demonstrated the knowledge flow with an actual cinematic narrative
Distributed Probabilistic Learning for Camera Networks
No full textProbabilistic approaches to computer vision typically assume a centralized setting, with the algorithm granted access to all observed data points. However, many problems in wide-area surveillance can benefit from distributed modeling, either because of physical or computations constraints. In this work we present an approach to estimation and learning of generative probabilistic models in a distributed context. In particular, we show how traditional centralized models, such as probabilistic principal component analysis (PPCA), can be learned when the data is distributed across a network of sensors. We demonstrate the utility of this approach on the problem of distributed affine structure from motion (SfM). Our experiments suggest that the accuracy of the accuracy of the learned probabilistic structure and motion models rivals that of traditional centralized factorization methods.Technical report DCS-TR-69
Challenges and directions of activity of president Yoon Suk Yeol’s administration
No full textThe purpose of the article is to describe the 2022 South Korean presidential election against the backdrop of a paradigm shift and to show the challenges and directions of Yoon Suk Yeol’s new administration. The author focuses on the research problems present in the new South Korean politics. Elements of change and continuity, which were also present in previous administrations are highlighted. In May 2022, Yoon Suk Yeol was sworn into the South Korea’s highest office. Yoon’s win in the presidential election ended a trend in which a decade of progressive rule was followed by a change to conservative rule. Since 1998, progressive and conservative presidents have alternated every two terms. The minimal difference in votes in favor of the conservative candidate reflected the divisions and social preferences of Koreans who favored a change from progressive to conservative government. The results of the 2022 presidential election revealed the polarization of South Korean society. Yoon will face a series of difficult challenges. In domestic politics, he must confront the housing crisis, widespread dissatisfaction with economic inequality, and generational tensions, among other issues. Yoon will also be challenged by the parliamentary majority currently held by the Democratic Party in the National Assembly. In foreign policy, South Korea’s new president advocates strengthening the alliance with the United States and cooperation with the Quad countries; he promises to improve relations with Japan, and to take steps toward South Korea playing a greater role in the world. In his inter-Korean policy, on the other hand, Yoon follows the traditional position of the conservatives, pledging to strengthen a policy of deterrence against acts of aggression and provocation by North Korea
Continuity and change in Yoon Suk Yeol's positioning of South Korea as a strong, proactive, and global middle power
No full textSouth Korean President Yoon Suk Yeol has stressed marked change with his predecessor in launching the nation as a strong, proactive, and globally oriented middle power. By way of testing four core assumptions on progressives and conservatives' policy proclivities, this article evaluates these (asserted) changes in South Korea's foreign security policy. It finds a sharp change in Seoul's policy toward the North's nuclear and missile program but continuity with the Moon administration in strengthening South Korea's force structure. Fearing potential American abandonment, the Yoon administration has further sought deeper integration with American forces on the Peninsula. Yoon breaking with China is a big policy shift, as is his taking incremental steps toward the tripartite alliance with the USA and Japan that is much-dreaded by Beijing. South Korea establishing ties with European countries and NATO on the other side of the world is also significant.Peer reviewe
STRATEGI KAMPANYE ANTI-FEMINISME YOON SEOK-YOOL DALAM PILPRES 2022 DI KOREA SELATAN
No full textGender issues often become a tool in every political contestation in countries that have not achieved gender equality. Likewise, in South Korea, there is still a strong patriarchal culture and the subordination of women as humans, especially in socio-political aspects. The political campaign carried out by on of the presidential candidates, Yoon Seok-Yeol from the People Power Party (PPP), promised to abolish the Ministry of Gender Equality dan Family because it did not have a high work ethic and was gender unfair. The deletion sparked renewed debate between voters young and old and both men and women. This institution has been around for a long time and has made a significant contribution to the struggle for gender equality in South Korea. This research uses a descriptive qualitative method that attempts to search, sort, and collect relevant information and relies on the author’s analytical strength. By using Dan Nimmo’s concept of Political Communication and Sara Mills’s Critical Discourse Analysis (CDA), the author tries to answer the campaign strategy carried out by Yoon and PPP which used anti-feminist issues to gain votes. The research results obtained were that Yoon and PPP deliberately divided young men and women because they became the voting base of their opposing political. So it promises to abolish the Ministry of Gender Equality and Family in order to attract votes from young men
Biotrickling Filtration for the Reduction of N<sub>2</sub>O Emitted during Wastewater Treatment: Results from a Long-Term In Situ Pilot-Scale Testing
No full textWastewater treatment plants (WWTPs) are a major source of N2O, a potent greenhouse gas with 300 times higher global warming potential than CO2. Several approaches have been proposed for mitigation of N2O emissions from WWTPs and have shown promising yet only site-specific results. Here, self-sustaining biotrickling filtration, an end-of-the-pipe treatment technology, was tested in situ at a full-scale WWTP under realistic operational conditions. Temporally varying untreated wastewater was used as trickling medium, and no temperature control was applied. The off-gas from the covered WWTP aerated section was conveyed through the pilot-scale reactor, and an average removal efficiency of 57.9 ± 29.1% was achieved during 165 days of operation despite the generally low and largely fluctuating influent N2O concentrations (ranging between 4.8 and 96.4 ppmv). For the following 60-day period, the continuously operated reactor system removed 43.0 ± 21.2% of the periodically augmented N2O, exhibiting elimination capacities as high as 5.25 g N2O m-3·h-1. Additionally, the bench-scale experiments performed abreast corroborated the resilience of the system to short-term N2O starvations. Our results corroborate the feasibility of biotrickling filtration for mitigating N2O emitted from WWTPs and demonstrate its robustness toward suboptimal field operating conditions and N2O starvation, as also supported by analyses of the microbial compositions and nosZ gene profiles.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.Sanitary Engineerin
Translanguaging and identities: Bilingual language and literacy practices in a Spanish-English two-way immersion classroom
No full textThe purpose of the present study is to understand the complexity of bilinguals’ language and literacy practices in relation to the dynamics of identity construction in Spanish-English two- way immersion practices. For this reason, using a comparative case study, this study investigates both Spanish-English bilinguals' and English-Spanish bilinguals’ learning to speak and write in two languages. Data show how these bilinguals, who come from Spanish-speaking homes and English-speaking homes, draw upon their linguistic repertoires to make sense of their worlds as well as how their teachers offered “transformative spaces for the performances and embodiment of bilingual (developing) identities that contributed to critical and creative learning” (Creese & Blacklege, 2015, p. 28). Therefore, this study centers on bilinguals’ language and literacy practices in relation to their developing identities, which are performed through the deployment of their linguistic repertoires.
This comparative case study explores four bilinguals’ language and literacy practices in terms of learning through translanguaging as well as their learning to speak and write in a home language and an additional language, in relation to their identities. In the literature on translanguaging, scholars have examined Spanish-English translanguaging practices in relation to their identities in bilingual school settings. Furthermore, scholars have already investigated the relationship between language and literacy practices of emergent bilinguals in relation to their developing identities. However, none of them explored the intersection between primary grade bilinguals’ translanguaging, identities, and language and literacy practices in Spanish-English two-way immersion school contexts. For these reasons, this study attempted to fill the gap.
Drawing on the poststructuralist’s notions of subjectivity and power, this study links bilingual children’s alternating language use, within and across sentences, to the performances of their identities. In this study, identities are defined how people invest in language, how they use language, and how they translanguage between and across two or more languages. Findings point to the assumption that bilinguals enact their bilingualism as a way of identity performance. Bilinguals performed their bilingual identities and/or negotiated their emerging bilingual identities through the deployment of their linguistic repertoires. Findings further indicate that social identities shape and are shaped by language and literacy practices that the students performed in school and at home. The cases of the focal students show that even though language and literacy development are closely related, there are cases that demonstrate that bilingual learning is bidirectional. These bilingual young learners learned to speak and write in both languages when the linguistic, emotional, and social dimensions of their developing identities were legitimized (Norton Peirce, 1995, 2016).
Bi-/Multilingual language policies are required to empower learners of culturally and linguistically diverse groups to express themselves in classrooms. Further study may examine language use and the frequency of translanguaging by presenting its quantitative and qualitative comparison between a two-way immersion classroom and an English-only classroom. The way the teachers and students engage in translanguaging practices as a resource for emergent bilinguals to allow them to socialize into appropriate forms of oral and written languages remains understudied. Additionally, understanding these emergent bilinguals’ writing processes in depth over a longer period of time would allow for educators and stakeholders to implement evidence- based decisions and policies.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-12-01The student, Nakyung Yoon, accepted the attached license on 2019-11-22 at 18:10.The student, Nakyung Yoon, submitted this Dissertation for approval on 2019-11-26 at 16:54.This Dissertation was approved for publication on 2019-12-01 at 10:21.DSpace SAF Submission Ingestion Package generated from Vireo submission #14597 on 2020-02-28 at 17:36:45Made available in DSpace on 2020-03-02T22:38:46Z (GMT).

Abstract:
This project investigates the structural consistency between constitutional axial polarity and elite athletic specialization. Static precision disciplines (archery, shooting) align with Vesicotonic (3S) polarity, sprint propulsion aligns with Cholecystonic (2N) polarity, and aquatic propulsion aligns with Pulmotonic (1N) polarity. The study proposes a layered stabilization-propulsion model rather than a static–dynamic opposition framework.
