Online anomaly detection using dimensionality reduction techniques for HTTP log analysis

2015

Modern web services face an increasing number of new threats. Logs are collected from almost all web servers, and for this reason analyzing them is beneficial when trying to prevent intrusions. Intrusive behavior often differs from the normal web traffic. This paper proposes a framework to find abnormal behavior from these logs. We compare random projection, principal component analysis and diffusion map for anomaly detection. In addition, the framework has online capabilities. The first two methods have intuitive extensions while diffusion map uses the Nyström extension. This fast out-of-sample extension enables real-time analysis of web server traffic. The framework is demonstrated using …

Online user survey on current mobile augmented reality applications

2011

Augmented reality (AR) as an emerging technology in the mobile computing domain is becoming mature enough to engender publicly available applications for end users. Various commercial applications have recently been emerging in the mobile consumer domain at an increasing pace — Layar, Junaio, Google Goggles, and Wikitude are perhaps the most prominent ones. However, the research community lacks an understanding of how well such timely applications have been accepted, what kind of user experiences they have evoked, and what the users perceive as the weaknesses of the various applications overall. During the spring of 2011 we conducted an online survey to study the overall acceptance and user…

Research literature clustering using diffusion maps

2013

We apply the knowledge discovery process to the mapping of current topics in a particular field of science. We are interested in how articles form clusters and what are the contents of the found clusters. A framework involving web scraping, keyword extraction, dimensionality reduction and clustering using the diffusion map algorithm is presented. We use publicly available information about articles in high-impact journals. The method should be of use to practitioners or scientists who want to overview recent research in a field of science. As a case study, we map the topics in data mining literature in the year 2011. peerReviewed

End-users Co-create Shared Information for a More Complete Real-time Maritime Picture

2017

European Union Member States are working towards an integrated maritime surveillance and deeper information sharing and implementation of Common Information Sharing Environment. Value networks aiming at co-creation, need active facilitation, and relevant platforms for open cooperation. This study analysed scenario analytics, and narrative documents from projects CoopP, CISE, and MARISA by using a Data Extraction Table to classify both objects and phenomenon relevant to European maritime information sharing systems. The object and phenomenon rows are grouped under a European Coast Guard Functions, CGFs framework, to better understand their occurrence and interdependencies. This paper finds t…

The Relationships between Pre-Service Primary Teachers’ Teaching and Instructing/Coaching Orientations, and Their Perceived Strengths in Teaching Phy…

2014

Abstract. This study explored if the orientations towards instructing/coaching in physical activities (PA) and teaching physical education (PE) affect the perceived strengths in teaching PE at the primary level (PSTPEs). The orientations were considered as socializing factors into teaching PE. In this study, the perceived strengths were divided into discipline - and pupil - focused strengths. Online questionnaire was used to collect the data from 386 first year pre - service primary teachers before their first PE course of formal teacher education, to expose the acculturative influences of the orientations. Cross tabulation and logistic regression were used to analyze the relationships. The…

Edutec : revista electrónica de tecnología educativa

2013

Resumen tomado de la publicación La aparición de pizarras digitales interactivas en las aulas y la posibilidad de asociarlas a las TIC ha permitido investigar nuevos cauces de comunicación entre el profesorado y el alumnado. Las pizarras digitales a parte de utilizar elementos multimedia: imágenes, sonidos, vídeos, etc. también pueden asociarse a las TIC para compartir de manera automática con el alumnado todos los contenidos que se muestran en ellas. Tomando como base esta idea hemos creado la aplicación web “Pizarra digital en casa” URL: http://hortamajor.edu.gva.es/pizarraencasa. ESP

Aprender inglés utilizando una red social: Explorando el uso de la red Ning por parte de estudiantes de segunda lengua

2013

Este artículo describe un estudio piloto llevado a cabo con estudiantes de Inglés 5 (nivel B+) en la Universidad de Valencia, la cual incorporó una red social para estudiar inglés fuera del horario lectivo. La herramienta seleccionada fue la web Ning, porque se centraba en el grupo y ofrecía toda una serie de herramientas interesantes – blogs, chats and foros de discusión – que tenían potencial para el aprendizaje del inglés. Los resultados indican que el uso del Ning en combinación con el contacto cara a cara contribuyó a la comunicación y la discusión en inglés y sirvió para estimular la colaboración de los estudiantes y la motivación a participar. Los miembros del Ning también cumplieron…

Sosiaalisen intranetin käyttö organisaation vuorovaikutusympäristönä : asiantuntijatyötä tekevien käsityksiä ja kokemuksia

2014

Tämän tutkimuksen tavoitteena oli ymmärtää sosiaalisen intranetin käyttöä organisaation vuorovaikutusympäristönä asiantuntijatyötä tekevien näkökulmasta. Tavoitetta lähestyttiin tutkimalla asiantuntijatyötä tekevien käsityksiä ja kokemuksia sosiaalisen intranetin käytöstä ja sosiaalisen intranetin käyttöönotosta heidän organisaatiossaan. Lisäksi pohdittiin sosiaalisen intranetin viestintä- ja vuorovaikutustehtävää organisaatiossa sekä asiantuntijatyötä tekevien näkemyksiä ja odotuksia sosiaalisen intranetin tulevaisuudesta. Tutkimus toteutettiin laadullisia menetelmiä käyttäen. Aineisto kerättiin haastattelemalla kahdeksaa kohdeorganisaation asiantuntijatyötä tekevää teemahaastattelurunkoa …

On Temporal Aspects in Cross-Cultural e-Collaboration Between Finland and Japan Research Teams

2018

Time is an essential dimension in cross-cultural e-collaboration among research project teams. Understanding temporal aspects and project dynamics in cross-cultural research e-collaboration and related processes can improve team members' skills in cross-cultural communication and increase their cultural competence. The present case cultures are Finnish and Japanese, and the case universities are the University of Jyväskylä (Finland) and Keio University (Japan). Three issues are addressed in this article. First, cultural dimensions and time models in the cross-cultural e-collaboration context are discussed. Second, temporal aspects related to e-collaboration activities are introduced. Third,…
