Introduction of Multiflow for HSDPA
2012
This paper introduces a multi-cell transmission scheme for High-Speed Downlink Packet Access (HSDPA) networks, called Multiflow. In this concept, downlink data is transmitted to a user terminal at the border of two cells from one or both of the cells. The cells may belong to same NodeB or to two different NodeBs. The data flows are separated by different scrambling codes used by each associated cell, thus the flows can be treated independently. This provides increased multi-user diversity by means of flexibility in downlink resource management, in addition to the spatial diversity of multiple transmission locations. Another important gain mechanism for this scheme is realized by short-term …
Cluster-Based RF Fingerprint Positioning Using LTE and WLAN Outdoor Signals
2015
In this paper we evaluate user-equipment (UE) positioning performance of three cluster-based RF fingerprinting methods using LTE and WLAN signals. Real-life LTE and WLAN data were collected for the evaluation purpose using consumer cellular-mobile handset utilizing ‘Nemo Handy’ drive test software tool. Test results of cluster-based methods were compared to the conventional grid-based RF fingerprinting. The cluster-based methods do not require grid-cell layout and training signature formation as compared to the gridbased method. They utilize LTE cell-ID searching technique to reduce the search space for clustering operation. Thus UE position estimation is done in short time with less comput…
An Approach for Network Outage Detection from Drive-Testing Databases
2012
A data-mining framework for analyzing a cellular network drive testing database is described in this paper. The presented method is designed to detect sleeping base stations, network outage, and change of the dominance areas in a cognitive and self-organizing manner. The essence of the method is to find similarities between periodical network measurements and previously known outage data. For this purpose, diffusion maps dimensionality reduction and nearest neighbor data classification methods are utilized. The method is cognitive because it requires training data for the outage detection. In addition, the method is autonomous because it uses minimization of drive testing (MDT) functionalit…
The influence of dataset size on the performance of cell outage detection approach in LTE-A networks
2015
The configuration and maintenance of constantly evolving mobile cellular networks are getting more and more complex and hence expensive. Self-Organizing Networks (SON) concept is an umbrella term for the set of automated solutions for network operations proposed by 3rd Generation Partnership Project (3GPP) group. Automated cell outage detection is one of the components of SON functionality. In early studies our research group developed data-driven approach for the detection of malfunctioning cells. In this paper we investigate the performance of the proposed solution as a function of the density of active users and the size of observation interval. The evaluation is conducted in Long Term E…
Visual Distraction Effects of In-Car Text Entry Methods
2017
Three text entry methods were compared in a driving simulator study with 17 participants. Ninety-seven drivers’ occlusion distance (OD) data mapped on the test routes was used as a baseline to evaluate the methods’ visual distraction potential. Only the voice recognition-based text entry tasks passed the set verification criteria. Handwriting tasks were experienced as the most demanding and the voice recognition tasks as the least demanding. An individual in-car glance length preference was found, but against expectations, drivers’ ODs did not correlate with incar glance lengths or visual short-term memory capacity. The handwriting method was further studied with 24 participants with instru…

The world is your oyster! : a material package for teaching handcrafts through CLIL
2014
Globalisoituvassa, verkottuvassa ja monikulttuuristuvassa maailmassa kyky kommunikoida vierailla kielillä ja kulttuurien tuntemus muuttuvat yhä tärkeämmiksi taidoiksi, joita myös suomalaisen koulun on kyettävä välittämään oppilaille. Eräs lähestymistapa tämän tavoitteen toteuttamiseksi on Content and Language Integrated Learning eli CLIL, jonka mukaisessa opetuksessa keskitytään sekä käytetyn vieraan kielen että käsiteltävänä olevan oppiaineen sisällön oppimiseen. CLIL mahdollistaa vieraan kielen käytön paitsi oppimisen kohteena, myös sen välineenä, mikä kasvattaa oppilaiden kommunikaatiotaitoja ja motivaatiota kielen oppimiseen. Tämä opinnäytetyö tarjoaa opettajien käyttöön oppimateriaalip…
Det nøtte itj å vårrå flink ålein : innføring av telemedisinsk samhandling i norske kommuner
2013
Innledning Innføring av telemedisinske tjenester har vist seg å være komplekse, fordi det i en telemedisinsk innovasjon utvikles nye tjenester, prosesser og organisasjonsformer. Det er forsket mye på slike innføringer på sykehus, men vi vet lite om hvordan dette foregår i norske kommuner. Derfor har vår problemstilling vært: Hvordan foregår innføring av telemedisinske tjenester i norske kommuner? Materiale og metode For å besvare problemstillingen har vi brukte en kvalitativ metode med fire fokusgruppeintervju med 24 informanter fra 21 kommuner i tre helseregioner. Vi har brukt implementeringsmodellene Normalization Process Theory og FITT- Framework for å belyse våre funn. Resultater Helsem…
