LiveSketch: Query Perturbations for Guided Sketch-based Visual Search

LiveSketch is a novel algorithm for searching large image collections using hand-sketched queries. LiveSketch tackles the inherent ambiguity of sketch search by creating visual suggestions that augment the query as it is drawn, making query specification an iterative rather than one-shot process that helps disambiguate users' search intent. Our technical contributions are: a triplet convnet architecture that incorporates an RNN based variational autoencoder to search for images using vector (stroke-based) queries; real-time clustering to identify likely search intents (and so, targets within the search embedding); and the use of backpropagation from those targets to perturb the input stroke sequence, so suggesting alterations to the query in order to guide the search. We show improvements in accuracy and time-to-task over contemporary baselines using a 67M image corpus.Comment: Accepted to CVPR 201

Injectivity radius of manifolds with a Lie structure at infinity

Using Lie groupoids, we prove that the injectivity radius of a manifold with a Lie structure at infinity is positive

Xylitol in Preventing Dental Caries

Abstract Problem: Dental caries is a common form of tooth infection among adults and children. The disease is easily transmissible, and therefore a great focus should be put on prevention to ensure healthy and proper oral hygiene for the population. Xylitol use has been proposed as one of the most effective preventive interventions against dental caries. Methods: The literature review engaged different electronic databases such as PubMed, MEDLINE, Google Scholar, and Cochrane Library in evaluating the effectiveness of xylitol use in preventing dental caries in both children and adults. Articles used in the review were published between 2016 and 2021 to ensure the relevance of the research. Significant findings: Many studies have revealed definitive evidence that xylitol is highly effective in preventing dental caries in both children and adults. Conclusion: Conclusively, dental caries is a common form of tooth infection among adults and children. For this infection, prevention is essential, and one of the most effective strategies for prevention is the application and utilization of xylitol. A large number of studies have demonstrated that xylitol is highly effective in the prevention of dental caries among the population. However, further research should be conducted to develop proper guidelines on its application in preventative interventions.https://scholarscompass.vcu.edu/denh_student/1026/thumbnail.jp

Integrated marketing communications plan for online newspaper : case : ess.fi of Mediatalo Esa

The thesis is designed as an improved integrated marketing communications (IMC) plan for the online newspaper ESS.fi published by Mediatalo ESA, a leading media company in Lahti region. The identified problems are that the awareness of customers of ESS.fi has been low and the competition from big players has been fierce. Analysis of this study is conducted by qualitative method, on the basis of deductive approach. The data collection process consisted of the interviews and informative e-mails with three members of the Marketing Department. The theoretical part provides a framework of the integrated marketing communications planning including promotional tools and a creative brief which describes the requirements of the ad used in the campaign. In the empirical part, the external factors of the Finnish newspaper industry, competitor analysis and internal factors of the case company are examined as a base for the suggested IMC plan. Following every single step of the IMC planning process, the plan tries to raise the awareness level of Mediatalo ESA’s customers of the online newspaper ESS.fi and increase the number of subscriptions by the end of the year 2014
