Mobiiliopetuksen käyttömahdollisuuksia : oppilaiden omien mobiililaitteiden käyttö peruskoulun alakoulun opetuksessa
2015
Muutaman viime vuoden aikana mobiililaitteiden käyttö kouluissa on yleistynyt. Tämä on osittain aiheuttanut ristiriitaista keskustelua laitteiden käytöstä opetuksessa. Osa opettajista on ottanut mobiililaitteet opetuskäyttöön innokkaasti. Mobiiliopetuksen mahdollisuuksia ei kuitenkaan ole vielä kovin paljon tutkittu. Tällä tutkimuksella oli tarkoitus selvittää, mitä mahdollisuuksia oppilaiden omat mobiililaitteet tarjoavat opetukseen. Aineiston analyysissa pyrittiin etsimään tietoa siitä, miten ongelma-perustaisen opetuksen menetelmä ja pelillisyys vaikuttavat opetus- ja oppimisprosessissa, kun opiskelumenetelmänä käytetään mobiilioppimista ja oppilaiden omia mobiililaitteita. Tutkimus teht…
Adaptive Service Offloading for Revenue Maximization in Mobile Edge Computing With Delay-Constraint
2019
Mobile Edge Computing (MEC) is an important and effective platform to offload the computational services of modern mobile applications, and has gained tremendous attention from various research communities. For delay and resource constrained mobile devices, the important issues include: 1) minimization of the service latency; 2) optimal revenue maximization; 3) high quality-of-service (QoS) requirement to offload the computational service offloading. To address the above issues, an adaptive service offloading scheme is designed to provide the maximum revenue and service utilization to MEC. Unlike most of the existing works, we consider both the delay-tolerant and delay-constraint services i…
Digital communication environments in the workplace
2019
Digital communication environments consist of various kinds of communication technologies and collaboration platforms. These enable employees to communicate through text, audio, video, and graphics, often in an open and networked way. Complementing the popular stand-alone communication tools regularly used in workplaces, such as email and instant messaging, digital communication environments enable the sharing, editing, and storing of information publicly within the organization and sometimes externally among its stakeholders. This chapter reviews and analyzes digital communication environments as well as their affordances and constraints for communication and social interaction in the work…
Evaluation of Ensemble Machine Learning Methods in Mobile Threat Detection
2017
The rapid growing trend of mobile devices continues to soar causing massive increase in cyber security threats. Most pervasive threats include ransom-ware, banking malware, premium SMS fraud. The solitary hackers use tailored techniques to avoid detection by the traditional antivirus. The emerging need is to detect these threats by any flow-based network solution. Therefore, we propose and evaluate a network based model which uses ensemble Machine Learning (ML) methods in order to identify the mobile threats, by analyzing the network flows of the malware communication. The ensemble ML methods not only protect over-fitting of the model but also cope with the issues related to the changing be…
Using Sport and Wellness Technology to Promote Physical Activity: An Intervention Study among Teenagers
2019
Life-long physical activity patterns are established during teenage years. Thus, promoting physical activity for teenagers is important. Sport and wellness technology shows promise for promoting physical activity. Yet, its research with teenage populations is sparse. This intervention study focused on whether using a sport and wellness technology application could affect the physical activity intention of teenagers, its antecedents, and the antecedents’ effects on intention by using the theory of planned behavior combined with the concept of self-efficacy as a theoretical framework. The results showed no statistically significant difference between the intervention and the control group in …
Protection against reverse engineering in ARM
2020
With the advent of the mobile industry, we face new security challenges. ARM architecture is deployed in most mobile phones, homeland security, IoT, autonomous cars and other industries, providing a hypervisor API (via virtualization extension technology). To research the applicability of this virtualization technology for security in this platform is an interesting endeavor. The hypervisor API is an addition available for some ARMv7-a and is available with any ARMv8-a processor. Some ARM platforms also offer TrustZone, which is a separate exception level designed for trusted computing. However, TrustZone may not be available to engineers as some vendors lock it. We present a method of appl…
3D-grafiikan optimointi mobiilialustalle Unity-ympäristössä
2016
Mobiilimarkkinoilta löytyy hyvin laaja kirjo erilaisia mobiilipelejä. Mobiililaitteet ovat laajimmalle levinnyt tietokonemuoto. Viimevuosina mobiililaitteiden graafiset ominaisuudet ovat nousseet sellaiselle tasolle, että niillä voidaan renderöidä upeita 3Dympäristöjä reaaliajassa. Silti mobiililaitteet vaativat optimointia sulavaan peligrafiikan laskemiseen. Tämä pro gradu tutkielma paneutuu 3D-mobiiligrafiikan optimointiin keskittyen Unity-pelimoottoriin. Teoriaosuudessa käydään läpi 3D-grafiikan luomisen peruskäytänteitä siirtyen Unityn käyttämään OpenGL ES liukuhihnaan ja sen optimointimahdollisuuksiin. Käytännön osuudessa testataan kolmioiden, valaistuksen, sekä varjostimien vaikutusta…
Seamless Learning Environments in Higher Education with Mobile Devices and Examples
2016
The use of seamless learning environments that have the potential to support lifelong learning anytime and anywhere has become a reality. In this sense, many educational institutions have started to consider introducing seamless learning environments into their programs. The aim of this study is to analyze how various educational university programs implement the design elements for seamless learning environments with mobile devices. For that purpose, three cases involved in a Finnish teaching development project are explored by conducting semi-structured interviews with key participants. The themes of the interviews were related to the theoretical background for (mobile) seamless learning …
Tietotekniikan arkipäiväistymisen vaikutukset organisaatioon ja yksilöön
2015
Työntekijöiden omat laitteet ovat alkaneet viimevuosina yleistyä työkäytössä. Samalla myös organisaatiot ovat alkaneet tarjota työntekijöille vaihtoehtoja oman työlaitteen osalta, jotta työntekijät voisivat työskennellä laitteella joka tukee omaa työskentelyä parhaalla tavalla. Tietotekniikan kuluttajistumisella tarkoitetaan yleisesti kuluttajataustaisten tai yksilön omien laitteiden tuomista mukaan yrityskäyttöön. Lisäksi ilmiöstä on käytetty laajempaa kuvausta, joka ottaa huomioon laitteiden lisäksi sovellukset, teknologiat ja artefaktit. Tässä tutkimuksessa ilmiöllä havaittiin olevan moninaisia vaikutuksia organisaatioi-hin ja yksilöihin. Organisaatioiden tehokkuus ja innovaatio kasvaa t…
Can Digital Coaching Boost Your Performance? – A Qualitative Study among Physically Active People
2019
The use of sport and wellness technology devices among athletes is highly popular. At the same time the demand for easy to understand, clear, and personalized information is also growing. Instead of numbers, users need and want solutions. Digital coaching can offer solutions for this by providing valuable training data and offering guidance and instructions on how to improve the training. This exploratory study focuses on the experiences, needs, and wants regarding a digital coach application among physically active people, more precisely crosscountry skiers. We found that the digital coach was perceived to have motivational elements. It was also viewed having potential to increase the awar…
