Effect of Stem Snapping on Aspen Timber Assortment Recovery in Hemiboreal Forests
2020
Post-disturbance salvage logging mitigates economic loss after windthrow, and the value of salvaged timber is strongly linked to its quality and dimensions. We studied the occurrence of wind-induced damage of aspen in the hemiboreal forests of Latvia based on data from the National Forest Inventory and additional measurements. Individual tree data from three re-measurement periods were linked to follow a tree condition (live, broken, uprooted) and to link tree characteristics to a respective snag. Three linear models were developed to assess factors affecting the snapping height. An assortment outcome was calculated for undamaged and salvaged trees using the bucking algorithm, and timber va…
JaxoDraw: A graphical user interface for drawing Feynman diagrams
2003
JaxoDraw is a Feynman graph plotting tool written in Java. It has a complete graphical user interface that allows all actions to be carried out via mouse click-and-drag operations in a WYSIWYG fashion. Graphs may be exported to postscript/EPS format and can be saved in XML files to be used in later sessions. One of the main features of JaxoDraw is the possibility to produce LaTeX code that may be used to generate graphics output, thus combining the powers of TeX/LaTeX with those of a modern day drawing program. With JaxoDraw it becomes possible to draw even complicated Feynman diagrams with just a few mouse clicks, without the knowledge of any programming language.
Coincidence of a high-fluence blazar outburst with a PeV-energy neutrino event
2016
The discovery of extraterrestrial very-high-energy neutrinos by the IceCube collaboration has launched a quest for the identification of their astrophysical sources. Gamma-ray blazars have been predicted to yield a cumulative neutrino signal exceeding the atmospheric background above energies of 100 TeV, assuming that both the neutrinos and the gamma-ray photons are produced by accelerated protons in relativistic jets. Since the background spectrum falls steeply with increasing energy, the individual events with the clearest signature of being of an extraterrestrial origin are those at PeV energies. Inside the large positional-uncertainty fields of the first two PeV neutrinos detected by Ic…
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…
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…
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…
Elena Pulcini, La cura del mondo. Paura e responsabilità in età globale.
2010
Elena Pulcini offre in questo libro una Zeitdiagnose delle due patologie che caratterizzano l’età globale: l’ “individualismo illimitato”, che coinvolge la struttura antropologica dell’individuo, e il “comunitarismo endogamico”, che interessa le forme di costituzione del legame sociale. Una diagnosi accurata di tali derive patologiche della globalizzazione indica nella sfera emotiva una profonda scissione tra l’assenza e l’eccesso di pathos: questa è la premessa dell’intera indagine filosofico-sociale condotta dall’autrice, che si propone di affrontare il problema in termini normativi. Si presentano a tal fine i lineamenti di un “normativismo eretico”, che ponga in primo piano le motivazion…
Flow Velocity Measurements in Vegetated Channels
2002
Understanding of the hydraulics of flow over vegetation is very important to support the management of fluvial processes. In this paper the flow over flexible bottom vegetation is experimentally studied. A two-dimensional-acoustic doppler velocimeter is used to measure the local flow velocities for different vegetation concentrations, discharges, and flume slopes. The influence of vegetation concentration and the depth/vegetation height ratio on the measured velocity profiles is analyzed. All measured velocity distributions are S-shaped and exhibit a three-zone profile. The relationship between the velocity distribution and the turbulence intensity distribution is also analyzed. The charact…
Open formats and interfaces for exchange of public information
2003
Masteroppgave i informasjons- og kommunikasjonsteknologi 2003 - Høgskolen i Agder, Grimstad Electronic reporting is an important part of all national eGovernment initiatives. XML4DR is a standard based on XML, proposed by a consortium funded by the European Commission. An application used for reporting from municipalities to central government has been developed by Comfact AB. A platform independent application will allow each municipality to freely chose tools such as browser, text processor and operating system. A platform independent application will rely on either open standards or a set of vendor specific pieces of code for the deviation form the standard. In this thesis I have evaluat…
