Enabling type differentiated explainable queries across modalities for different fashion items
No full textOne of the biggest differences between shopping online and in person is the limited scope and expressibility of the queries that current systems allow and can handle. In person, users often employ a combination of linguistic and visual tools at their disposal to create complex queries. Handling such queries requires modeling relationships between products of the same type, products of different types, products and outfits, and products and their attributes. In this paper, we propose a system that models these relationships by: (i) building a robust visual representation of items that captures notions of similarity and compatibility between products, (ii) learning to predict low-level (color, type) and high-level (style, brand) attributes of the items from their visual representations, and (iii) learning segment-wise maps of outfits to items. For each part, we evaluate the model by demonstrating its performance on relevant tasks like outfit completion, item retrieval, etc., and flexibility through example results for complex queries.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-05-01The student, Krishna Dusad, accepted the attached license on 2019-04-26 at 11:30.The student, Krishna Dusad, submitted this Thesis for approval on 2019-04-26 at 11:39.This Thesis was approved for publication on 2019-04-26 at 15:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #13945 on 2019-08-22 at 15:08:49Made available in DSpace on 2019-08-23T20:36:13Z (GMT).

Analyses of contact networks of community dogs on a university campus in Nakhon Pathom, Thailand
No full textFree-roaming dogs have been identified as an important reservoir of rabies in many countries including Thailand. There is a need for novel insights to improve current rabies control strategies in these countries. Network analysis is commonly used to study the interactions between individuals or organizations and has been applied in preventive veterinary medicine. However, contact networks of domestic free-roaming dogs are mostly unexplored. The objective of this study was to explore the contact network of free-roaming dogs residing on a university campus. Three one-mode networks were created using co-appearances of dogs as edges. A two-mode network was created by associating the dog with the pre-defined area it was seen in. The average number of contacts a dog had was 6.74. The normalized degree for the weekend network was significantly higher compared to the weekday network. All one-mode networks displayed small-world network characteristics. Most dogs were observed in only one area. The average number of dogs which shared an area was 8.67. In this study, we demonstrated the potential of observational methods to create networks of contacts. The network information acquired can be further used in network modeling and designing targeted disease control programs
Studies in Logic: A Dialogue Between the East and the West. Homage to Bimal Krishna Matilal
No full textTen essays of this book, two of which are written in Sanskrit, range from modern logic to classical Indian theories of inference. Classical Indian philosophy comprising Pracina and Navya- Nyaya, Sankhya, Buddhist and Jaina logical and philosophical standpoints are discussed in most modern technical terms of western philosophy, often with the aid of terminologies of modern logic. Similarly, western ideas propounded by the ancient Greek philosophers like Aristotle as well as contemporary philosophers such as Frege, Russell, Srawson, Kripke and many others are placed against the backdrop of classical Indian philosophy. The book will be immensely useful to those interested in stimulating meaningful dialogues between philosophical thinkings of India and the West. The book will also be of interest to those who aim at broadening the horizon of logic and philosoph
Applicability of the Global Land Evaporation Amsterdam Model Data for Basin-Scale Spatiotemporal Drought Assessment
No full textDrought directly impacts the living organisms and environment, and thereby, its assessment is essential. Different drought indices require different data, which can be obtained based on models or in-situ measurements, demanding a significant amount of effort. Using remotely sensed (RS) data from satellites can facilitate this data acquisition. Nowadays, more and more satellite techniques are rising, highlighting the need to assess the accuracy of their data and the reliability of the results obtained by employing them. The Wet-environment Evapotranspiration Precipitation Standardized Index (WEPSI) has shown good performance in drought monitoring and assessment, especially for agricultural purposes. This chapter employs the Global Land Evaporation Amsterdam Model (GLEAM) data to investigate its applicability in the Lempa River basin drought assessment using WEPSI. In this order, evaluated data obtained from the Water Evaluation and Planning system (WEAP) were used as the basis for comparison. Precisely, a comparison was made with GLEAM and WEAP-based data as well as WEPSI time series based on these two datasets. The results show a relatively high similarity between these two datasets and calculated WEPSI drought indices. This validates the good performance of GLEAM-based data in drought monitoring and assessment based on WEPSI.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.Water Resource
Pesticide Reduction Sustainability of Bt Technology in India
No full textThe primary focus of the study is the changes that occurred in the pesticide-use structure of cotton production sector of India, owing to the diffusion of Bacillus thuringiensis (Bt) technology. Studies from different countries show that transgenic Bt crops can reduce chemical pesticide use with positive economic, environmental, and health effects. However, most of these studies build on cross-section survey data, so that longer term effects are uncertain. Bt resistance and secondary pest outbreaks may potentially reduce or eliminate the benefits over time, especially in developing countries where refuge strategies are often not implemented. Here, data from a unique panel survey of cotton farmers, conducted in India between 2002 and 2008, show that the Bt pesticide reducing effect has been sustainable. In spite of an increase in pesticide sprays against secondary pests, total pesticide use has decreased significantly over time. Bt has also reduced pesticide applications by non-Bt farmers. These results mitigate the concern that Bt technology would soon become obsolete in small farmer environments. The survey data on actual pesticide use in farmers’ fields complement previous entomological research.Crop Production/Industries, Research and Development/Tech Change/Emerging Technologies,
A critical assessment of technical advances in pharmaceutical removal from wastewater – A critical review
No full textUse of pharmaceutical products has seen a tremendous increase in the recent decades. It has been observed that more than thirty million tons of pharmaceuticals are consumed worldwide. The used pharmaceutical products are not completely metabolized in human and animal body. Therefore, they are excreted to the environment and remain there as persistent organic chemicals. These compounds emerge as toxic contaminants in water and affect the human metabolism directly or indirectly. This literature review is an endeavour to understand the origin, applications and current advancement in the removal of pharmaceuticals from the environment. It discusses about the pharmaceuticals used in medical applications such diagnosis and disease treatment. In addition, it discusses about the recent approaches applied in pharmaceutical removal including microbial fuel cells, biofiltration, and bio nanotechnology approaches. Moreover, the challenges associated with pharmaceutical removal are presented considering biological and environmental factors. The review suggest the potential recommendations on pharmaceutical removal.The corresponding author Prof. Vinay Kumar is thankful to all the co-authors for their collaborative efforts in writing this paper.

Synthesis of Indonesian Kaolin-nZVI (IK-nZVI), Evaluation for the Removal of Pb(II) from Waste Streams
No full textRemoval of toxic pollutants such as heavy metals from wastewater is of utmost importance in the current century. Heavy metals have severed a big problem in the world. Several tools have been established to mitigate this problem. In this research paper, Indonesian Kaolin-nano zerovalent iron (IK-nZVI) was synthesized as a model adsorbent for Pb(II) removal from wastewater. The efficiency of IK supported nZVI for Pb(II) removal efficiency was estimated by accompanying batch experiments. The examined parameters included the amount of IK-nZVI, the concentration of Pb(II) removal and the effect of pH. The results revealed that the IK-nZVI was efficient for the removal of Pb(II) from waste water. © 2020 Author(s).The author Lakkaboyana Sivarama Krishna is grateful to the Graduate School and The Thailand Research Fund (IRG578001), Chulalongkorn University for providing financial support, Senior Postdoctoral Fellowship under Rachadapisaek Sompote Fund
Redox-Responsive Nanocapsules for the Spatiotemporal Release of Miltefosine in Lysosome: Protection against Leishmania
No full textLeishmaniasis, a vector-borne disease, is caused by intracellular parasite Leishmania donovani. Unlike most intracellular pathogens, Leishmania donovani are lodged in parasitophorous vacuoles and replicate within the phagolysosomes in macrophages. Effective vaccines against this disease are still under development, while the efficacy of the available drugs is being questioned owing to the toxicity for nonspecific distribution in human physiology and the reported drug-resistance developed by Leishmania donovani. Thus, a stimuli-responsive nanocarrier that allows specific localization and release of the drug in the lysosome has been highly sought after for addressing two crucial issues, lower drug toxicity and a higher drug efficacy. We report here a unique lysosome targeting polymeric nanocapsules, formed via inverse mini-emulsion technique, for stimuli-responsive release of the drug miltefosine in the lysosome of macrophage RAW 264.7 cell line. A benign polymeric backbone, with a disulfide bonding susceptible to an oxidative cleavage, is utilized for the organelle-specific release of miltefosine. Oxidative rupture of the disulfide bond is induced by intracellular glutathione (GSH) as an endogenous stimulus. Such a stimuli-responsive release of the drug miltefosine in the lysosome of macrophage RAW 264.7 cell line over a few hours helped in achieving an improved drug efficacy by 200 times as compared to pure miltefosine. Such a drug formulation could contribute to a new line of treatment for leishmaniasis.A.
