Using eye-movement modelling examples to improve critical reading of multiple webpages on a conflicting topic
2022
This project investigates the effects of an EMME intervention on undergraduates' sourcing when reading conflicting multiple texts on the Internet. Dependent variables: eye-movements on SERP, webs header, texts authors, and texts; use of source information in summaries; ideas from texts in summaries.
Search for supersymmetry in events with photons, bottom quarks, and missing transverse momentum in proton-proton collisions at a centre-of-mass energ…
2013
A search has been performed for the experimental signature of an isolated photon with high transverse momentum, at least one jet identified as originating from a bottom quark, and high missing transverse momentum. Such a final state may originate from supersymmetric models with gauge-mediated supersymmetry breaking in events in which one of a pair of higgsino-like neutralinos decays into a photon and a gravitino while the other decays into a Higgs boson and a gravitino. The search is performed using the full dataset of 7 TeV proton–proton collisions recorded with the ATLAS detector at the LHC in 2011, corresponding to an integrated luminosity of 4.7 fb−1. A total of 7 candidate events are o…
Measurement of the top quark pair production cross-section with ATLAS in the single lepton channel
2012
A measurement of the production cross-section for top quark pairs (t[bar over t]) in pp collisions at √s = 7 TeV is presented using data recorded with the ATLAS detector at the Large Hadron Collider. Events are selected in the single lepton topology by requiring an electron or muon, large missing transverse momentum and at least three jets. With a data sample of 35 pb[superscript −1], two different multivariate methods, one of which uses b-quark jet identification while the other does not, use kinematic variables to obtain cross-section measurements of σ[subscript t bar over t] = 187 ± 11 (stat.) [+18 over −17] (syst.) ± 6 (lumi.) pb and σ[subscript t bar over t] = 173 ± 17 (stat.) [+18 ove…
Monitoring and data quality assessment of the ATLAS liquid argon calorimeter
2014
The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It also provides a crucial input for measuring jets and missing transverse momentum. An advanced data monitoring procedure was designed to quickly identify issues that would affect detector performance and ensure that only the best quality data are used for physics analysis. This article presents the validation procedure developed during the 2011 and 2012 LHC data-taking periods, in which more than 98% of the proton-proton luminosity recorded by ATLAS at a centre-of-mass ener…
DOCUMENT MANAGEMENT USING CLUSTERING ALGORITHMS
2015
Document management systems are complex systems, which offer services as storage, versioning, metadata, security, as well as indexing and retrieval capabilities. Large numbers of documents could be automatically grouped into classes of documents, which contain similar information. Therefor we propose to use clustering methods in order to group the documents. Clustering is an important process in text mining used for groping documents based on their contents in order to extract knowledge. In this paper we will present some requirements for clustering algorithms for a document management system
Verkkoproosa : tutkimus dialogisesta kirjoittamisesta
2007
This theoretical work scrutinizes poetical aspects of writing in the web (blogs, chat, forums). The practice of writing called web prose use the elements of speech and textualize it. This brings web prose near the tradition of literature, not as art, but as style of prose writing. By using H-G Gadamer`s hermeneutics, philosophy of conversation and poetics, I ask how the tradition of writing comes in to the web. Web is scrutinized from the aspects of poetics, dialogue and publicity. The work examines language and genre from the approach of the writing studies. Dialoque has an important function also in the web prose, when writing is getting closer to conversation. At last part I ask what cha…
kLa MEASUREMENT IN BIOREACTORS
2010
For accurately measuring kLa in bioreactors the dynamic pressure method (DPM) was introduced by Linek et al. (1993). In this work a simplified version of the same method is discussed. With respect to the original DPM, the simplified version greatly simplifies data treatment. In fact final constant slope observable in the usual semi-log diagram of residual driving force versus time may be simply corrected to obtain the real kLa value with negligible inaccuracy. Experimental data obtained on a lab-size stirred tank reactor confirm all model predictions, including the feature that the adoption of large pressure changes may lead to a better accuracy.

Vortex shape in unbaffled stirred vessels: experimental study via digital image analysis
2011
There is a growing interest in using unbaffled stirred tanks for addressing certain processing needs. In this work, digital image analysis coupled with a suitable shadowgraphy-based technique is used to investigate the shape of the free-surface vortex that forms in uncovered unbaffled stirred tanks. The technique is based on back-lighting the vessel and suitably averaging vortex shape over time. Impeller clearance from vessel bottom and tank filling level are varied to investigate their influence on vortex shape. A correlation is finally proposed to fully describe vortex shape also when the vortex encompasses the impeller.
A Conceptual Framework for Using and Evaluating Web-Based Learning Resources in School Education
2010
Published version of an article from the journal:Journal of Information Technology Education. Also available from the publisher: http://www.jite.org/documents/Vol9/JITEv9p053-079Hadjerrouit743.pdf Web-based learning resources (WBLRs) have provided teachers with a wide range of new teachingexperiences that are not possible in traditional classroom. However, little research has beendone as to which approach to WBLRs is suitable to address issues that are pertinent to learning.This paper proposes a conceptual framework to explore the design and evaluation of WBLRs inschool education. The paper also examines the way in which the framework is used to evaluatestudents? and teachers? perceptions o…
