From Face-to-Face to Online UDeL Camps: Supporting Staff at Higher Education Institutions in Developing Universal Design for eLearning (UDeL)
2021
The TINEL Project is running a series of camps for staff at higher education institution to support them in developing inclusive eLearning. The first camp was conducted face-to-face, but the coronavirus pandemic meant that the second camp was conducted online. This created a case study in inclusive eLearning in itself and allowed us to experience and reflect on the challenges and opportunities of inclusive online teaching and learning. This paper presents the structure and content of the two camps, our reflections on moving from a face-to-face to an online situation and our elaboration how the UDL principles apply to eLearning to create Universal Design for eLearning (UDeL). We found that b…
Improving point matching on multimodal images using distance and orientation automatic filtering
2016
International audience; Speed Up Robust Features SURF is one of the most popular and efficient methods used for image registration task. In order to achieve a correct registration, a good matching of feature point is required. However in the case of multimodal images, the high and non-linear intensity changes between different modalities led to many outliers (mismatching of detected points) and consequently a fail in the registration. Therefore, in this paper we introduce an efficient method devoted to the detection and removal of such outlier. It's based on an automatic filtering of outliers on both distance and orientation between features points. We tested our proposed method on a set of…
ICDAR 2021 Competition on Historical Document Classification
2021
International audience; This competition investigated the performance of historical document classification. The analysis of historical documents is a difficult challenge commonly solved by trained humanists. We provided three different classification tasks, which can be solved individually or jointly: font group/script type, location, date. The document images are provided by several institutions and are taken from handwritten and printed books as well as from charters. In contrast to previous competitions, all participants relied upon Deep Learning based approaches. Nevertheless, we saw a great performance variety of the different submitted systems. The easiest task seemed to be font grou…
A Brief History of Forensic Radiology
2019
During the last two decades, forensic radiology showed, as never before, a rapid, widely diffuse, and substantial change in the legal, medical, anthropological, archaeological, and scientific approach to applications of forensic radiology itself.
Event legacy framework and measurement
2018
This article presents the development of a new approach for measuring mega sport event legacy and is based on the Olympic Games as a reference. The legacy of mega sport events has gained ever more ...
A framework for vertex reconstruction in the ATLAS experiment at LHC
2010
In anticipation of the first LHC data to come, a considerable effort has been devoted to ensure the efficient reconstruction of vertices in the ATLAS detector. This includes the reconstruction of photon conversions, long lived particles, secondary vertices in jets as well as finding and fitting of primary vertices. The implementation of the corresponding algorithms requires a modular design based on the use of abstract interfaces and a common Event Data Model. An enhanced software framework addressing various physics applications of vertex reconstruction has been developed in the ATLAS experiment. Presented in this paper are the general principles of this framework. A particular emphasis is…
Transcribing the "Estoria de Espanna" using crowdsourcing: Strategies and aspirations
2015
This paper examines the specific strategies for recruitment and retention of volunteer transcribers in use in two collaborative transcription projects: Transcribe Bentham (University College, London) and the Estoria de Espanna Digital Project (University of Birmingham). The aim of the paper is to review the strategies used by Transcribe Bentham, a more mature crowdsourced electronic transcription project, with a view to informing the strategies put into place in the Estoria project, which has started transcribing using crowdsourcing more recently. The paper discusses the difficulties faced by crowdsourced electronic transcription projects and how these have been and are being resolved in th…
Print and online newspapers as material artefacts
2014
Traditional newspaper journalism is in a state of crisis and there have been several attempts to overcome this. Many discourses have reiterated the triumphal march of a digital revolution in newspaper journalism and anticipated the end of the print newspaper. This moment calls for an in-depth analysis of reader habits of news consumption and use in order to understand the audiences for journalistic output and their relationship with the journalistic objects. In this study, we adopt a multi-method approach, integrating (1) qualitative content analysis of student essays dealing with the physicality of printed and online newspapers, (2) ethnographic observation of the use practices of readers…
Depth Enhancement by Fusion for Passive and Active Sensing
2012
This paper presents a general refinement procedure that enhances any given depth map obtained by passive or active sensing. Given a depth map, either estimated by triangulation methods or directly provided by the sensing system, and its corresponding 2-D image, we correct the depth values by separately treating regions with undesired effects such as empty holes, texture copying or edge blurring due to homogeneous regions, occlusions, and shadowing. In this work, we use recent depth enhancement filters intended for Time-of-Flight cameras, and adapt them to alternative depth sensing modalities, both active using an RGB-D camera and passive using a dense stereo camera. To that end, we propose …
Efficiency of QuEChERS approach for determining 52 pesticide residues in honey and honey bees
2016
A comparison between QuEChERS and other pesticide extraction procedures for honey and honey bee matrices is discussed. Honey bee matrix was extracted by solvent based procedure whereas solid phase extraction was the protocol for the honey matrix. The citrate buffered QuEChERS method was used for both matrices. The methods were evaluated regarding cost (equipment and reagents), time, accuracy, precision, sensitivity and versatility. The results proved that the QuEChERS protocol was the most efficient method for the extraction of the selected pesticides in both matrices. QuEChERS is the most economical and less time-consuming procedure.SPE and solvent-based extraction procedures show equivale…
