Mobikoli-mobiilisovelluksen äänisuunnittelu

Mobiilisovellusten lisääntymisen vuoksi on yrityksillä tarve sovellusten saamiseksi yritysten hyötykäyttöön kasvanut jatkuvasti. Erilaiset sovellukset tarvitsevat sekä kuvan että äänen osaamista. Opinnäytetyössäni selvitän, mitä asioita on otettava huomioon suunniteltaessa kuunnelmaa mobiililaitteelle. Tutkin mitä vahvuuksia ja heikkouksia mobiililaitteissa on. Työn toiminnallisuus on toteutettu lasten seikkailusatuna, joka pohjautuu GPS-paikannusjärjestelmän avulla toteutettuun karttapohjaiseen tarinaan. Siinä kuuntelija kiertää Kolin kansallismaisemissa saaden määrätyissä pisteissä kuunneltavakseen pienen tarinan. Toiminnallisessa osuudessa oli mukana äänisuunnittelu, karttojen suunnittelu, käsikirjoitus, verkko- ja mobiilisivujen kehitys, sekä ohjelmistosuunnittelu. Mobiilisovellus on julkaistu iOS-, Android- ja Windows Phone 8 – alustoille.Mobikoli – Sound Design for Mobile Application Commissioned by Tourist Guide for Northern Periphery (TG4NP) Summary As mobile applications are increasing, the need for harnessing that potential of applications for the use of companies will continue to increase. In my thesis, the issues considering sound design for mobile devices are investigated: Furthermore, the strengths and weaknesses of mobile devices are examined. The application is a map based adventure game for children where the listener hears a portion of a story while trekking through Koli National Park. The story portions are triggered by reaching specific locations. The application employs GPS technology. The functions included in the application are sound design, map design, scripting, web and mobile publishing and software design. The mobile application is published for iOS-, Android- and Windows Phone 8

Review of Learning in ICT-enabled Networks and Communities

This report is part of a project launched by IPTS with DG Education and Culture to study the innovations for learning, which are emerging in the new collaborative and informal settings enabled by ICT. The report gathers and analyses evidence from learning opportunities that are emerging in ICT-enabled networks and communities. In these new virtual spaces, participation is motivated by an interest to a topic, by creative production and by search for social connection. Online networks and communities emerge both within and across organisations as well as in a completely open and bottom-up manner. Accessing, following, and contributing to the communities can lead to a range of learning outcomes. New technologies afford tools and means for people to participate in communities in a personally meaningful way. However, not all individuals are necessarily equipped with skills or knowledge to benefit from these opportunities for their lifelong learning. Major challenges relate both to the initial barriers for accessing online communities with confident and critical digital competence and skills for self-regulated learning. Finding ways to identify, assess and certify relevant learning and new skills that can be obtained and practiced in these environments is a major task. The report argues that educational institutions should find ways to connect with and learn from these new learning approaches and settings in order to bring about their own transformation for the 21st century, and to support competence building for new jobs and personal development with a learner-centred and lifelong perspective.JRC.J.4-Information Societ

Investigation of the magnetic fluctuations in Tb2_2Sn2_2O7_7 ordered spin ice by high resolution energy-resolved neutron scattering

We have studied magnetically frustrated Tb$_2$Sn$_2$O$_7$ by neutron diffraction and high resolution energy-resolved neutron scattering. At 0.1 K, we observe short range magnetic correlations with a typical scale of 4 \AA, close to the near neighbor distance between Tb$^{3+}$ ions. %(3.686 \AA), This short range order coexists with ferromagnetic correlations and long range spin ice order at the scales of 18 and 190 \AA, respectively. Spin dynamics was investigated at a time scale down to 10$^{-9}$s, by energy-resolved experiments on a backscattering spectrometer. We observe a freezing of the spin dynamics for all length-scales, with a strong slowing down of the spin fluctuations when long range order settles in. We discuss the spin fluctuations remaining in the ground state in comparison with previous data obtained by muon spectroscopy.Comment: 6 pages, 5 figure

Spin dynamics in the ordered spin ice Tb2_2Sn2_2O7_7

Geometrical frustration is a central challenge in contemporary condensed matter physics, a crucible favourable to the emergence of novel physics. The pyrochlore magnets, with rare earth magnetic moments localized at the vertices of corner-sharing tetrahedra, play a prominent role in this field, with a rich variety of exotic ground states ranging from the "spin ices" \hoti\ and \dyti\ to the "spin liquid" and "ordered spin ice" ground states in \tbti\ and \tbsn. Inelastic neutron scattering provides valuable information for understanding the nature of these ground states, shedding light on the crystal electric field (CEF) level scheme and on the interactions between magnetic moments. We have performed such measurements with unprecedented neutron flux and energy resolution, in the "ordered spin ice" \tbsn. We argue that a new interaction, which involves the spin lattice coupling through a low temperature distortion of the trigonal crystal field, is necessary to account for the data
