An experimental HMM-based postal OCR system

It is almost universally accepted in speech recognition that phone- or word-level segmentation prior to recognition is neither feasible nor desirable, and in the dynamic (pen-based) handwriting recognition domain the success of segmentation-free techniques points to the same conclusion. But in image-based handwriting recognition, this conclusion is far from being firmly established, and the results presented in this paper show that systems employing character-level presegmentation can be more effective, even within the same HMM paradigm, than systems relying on sliding window feature extraction. We describe two variants of a Hidden Markov system recognizing handwritten addresses on US mail, one with presegmentation and one without, and report results on the CEDAR data set. 1. INTRODUCTION Any approach to speech and handwriting recognition must take into account that the signal is composed from a succession of alphabetic units (phonemes or graphemes). In the early work on speech recog..

Employing AI Applications to Authenticate People through Neural Networks

Artificial intelligence is used to develop techniques for verifying people by sensory factors. This article aims to design a robot to verify the entry of the authorized persons to the firms. This paper uses neural networks with artificial intelligence applications to authenticate people, while the program is based on testing four factors: the face, eye, voice, and handprint. The AI application depends on a mathematical algorithm to test the authority of staff; meanwhile, neural networks analyse and examine the visual systems that connect imaging devices (camera) with a computer. Moreover, this is done through the huge amount of data in a smart computer database that can be updated, with speed and objectivity, through the Internet to reach accurate results. The results indicate that the model designed for artificial intelligence has economic feasibility; in addition to that, it can help detect diseases that can affect employees by multiple parametric methods of verification

Sensory ways to indigenous multimodal literacies : Hands and feet tell the story

This chapter reports original research that asks the question: What are the ways of knowing, being, and communicating that are valued and practiced in Indigenous communities? Literacy curricula, internationally and nationally, typically do not take into account the multi-sensorial dimensions of non-Western forms of representation that go beyond narrow conceptions of print. For example, literacies are often conceived as drawing on print, visual, spatial, gestural, and audio modes, but the role of haptics and locomotion has typically received little attention. This chapter highlights examples of the multi-sensoriality of Indigenous literacies observed in participatory community research with an Indigenous school. It extends recent theories of sensory studies in the history and cultural anthropology of the senses, applying these principles to literacy education. Sensory literacies is a theoretical perspective that gives priority to the sensorial dimensions of the body and its role in communication in literacy practice, because without a sensing body, we cannot know about or communicate with the world. The data demonstrates how the forgotten role of the hands and feet in dominant theories of communication is central to Indigenous identity and literacies. Written by a white academic with an Indigenous researcher, the chapter problematises the privileging of narrow, logocentric, and Western forms of literacy and its implications for rethinking the role of the whole body in literacy and the literacy curriculum for Indigenous students

E-HOME, A LIFESTYLE AND COMFORTABLE TECHNOLOGY

Technology has become an essential part of our homes, which are places that should be easy and peaceful to live in. That’s why I imagine a concept that take all the technology necessary in your home, integrate it and make it simple and easy to use for everybody. This concept is based on idea that eliminates remote controls or something like this. Also this concept should propose you a lot of possible decision that you could take. These decisions refers on easy living in a normal home, such as climate, water temperature, lightning, multimedia, such as TV’s, VCR’s, DVD’s, but also decisions about eating, paying taxes, investments, interfaces with public institutions and so on. This concept I name it e-Home. I imagine this concept with many modules, refers on easy living in such a home, referring on what do you eat, calories consume, food storage and clothes and about possible decision to take in matter of paying and investments of your family.technology, interfaces, neural network, software, artificial intelligence

Treasure codes: augmenting learning from physical museum exhibits through treasure hunting

Previous studies have highlighted the difficulty that designers face in creating mobile museum guides to enhance small group experiences. In this paper, we report a study exploring the potential of mobile visual recognition technology (Artcodes) to improve users’ experiences in a visitor centre. A prototype mobile guide in the form of a treasure hunt was developed and evaluated by means of a field study comparing this technology with the existing personal guided tour. The results reveal a preference for the mobile guide amongst participants and show significant learning gains from pre-test to post-test compared with the pre-existing personal tour. Our observational analyses indicate how the mobile guide can be used to improve visitors’ learning experiences by supporting active discovery and by balancing physical and digital interactions. We further expand the concept of design trajectories to consider micro-scaffolding as a way of understanding and designing future public technologies

A relational post-processing approach for forms recognition

Optical Character Recognition (OCR) is used to convert paper documents into electronic form. Unfortunately the technology is not perfect and the output can be erroneous. Conversion then is generally augmented by manual error detection and correction procedures which can be very costly; One approach to minimizing cost is to apply an OCR post processing system that will reduce the amount of manual correction required. The post processor takes advantage of knowledge associated with a particular project; In this thesis, we look into the feasibility of using integrity constraints to detect and correct errors in forms recognition. The general idea is to construct a database of form values that can be used to direct recognition and consequently, make automatic correction

Monitor Sustainable Municipalities Report 2019 Key topic Circular Economy. Bertelsmann Stiftung Study 4 November 2019

At first sight, the concept for a recycling economy appears to be just the latest trend in the field of urban development, but in fact conversion to circular value creation also contains numerous oppor-tunities for the creation of long-term sustainable economic, social and environmental benefits for local communities. We have therefore chosen to look at this topic in this, our fourth, Monitor Report. Recycling Economy, Circular Value Creation and Cradle To Cradle are three concepts which – alt-hough each has a different main focus – basically all describe the same paradigm shift: away from a classic linear economy (“Take, Make, Use, Dispose”) towards a model based on restoration and regeneration. The recycling economy principle is actually anchored in the United Nations’ 17 Sustainable Devel-opment Goals, or SDGs. Goal 12 calls for sustainable consumption and sustainable production patterns. The recycling economy is also associated with a number of other sustainability goals, as it makes a significant contribution to their achievement. We are convinced that it is worth considering the applicability of the concept to local communities in Germany. What does transferring the recycling economy principle to local communities entail? How can towns be converted into “Recycling Cities”? Where are the obstacles and what potential is there? This Monitor Report is a first – it is the first bilingual version. With the kind permission of the Collab-orating Centre for Sustainable Consumption and Production (CSCP) in Wuppertal, we have issued their “Circular Economy Guidebook for Cities” in the original English with a German translation. We hope that, by looking at the bigger picture, we will also generate the impulse to consider how the topic can be adopted in (European) towns and cities, and what the resulting benefits could be. We are fully aware that a one-to-one transfer will not work. “One size fits all” does not apply to local communities. Although something that makes sense in Amsterdam, Copenhagen or Oslo may not necessarily work in towns, districts and local communities in Germany, it is definitely worth looking at how things are done in other countries. I would sincerely like to thank everyone who contributed to the creation of this Report, and especially the CSCP for its trust and invaluable cooperation. We hope you enjoy reading the Report, and look forward as always to your feedback and suggestions

A framework for re-thinking learning in science from recent cognitive science perspectives

Recent accounts by cognitive scientists of factors affecting cognition imply the need to reconsider current dominant conceptual theories about science learning. These new accounts emphasize the role of context, embodied practices and narrative-based representation rather than learners&rsquo; cognitive constructs. In this paper we analyze data from a longitudinal study of primary school children&rsquo;s learning to outline a framework based on these contemporary accounts, and to delineate key points of difference from conceptual change perspectives. The findings suggest this framework provides strong theoretical and practical insights into how children learn and the key role of representational negotiation in this learning. We argue that the nature and process of conceptual change can be re-interpreted in terms of the development of students&rsquo; representational resources.<br /

Comics and authorship : an introduction

If media authorship can be understood "as a site of cultural tension" (Johnson and Gray 2013, 10), then a deeper understanding of comics authorship will also provide clues regarding the sustaining—and constraining— of creative practices in other media ecologies and intermedial interactions (such as, for instance, adaptations). For comics, this implies combining insights from comics scholars, practitioners as well as agents involved in the publication and dissemination of comics. This issue, building on the findings of extant scholarship on authorship in comics and other media, hopes to provide incentive for further adventures into the (almost) unknown of comics authorship
